Also set derby.system.home on the server side, not the client side.

I don't think you need to pass all the system properties
to DriverManager.getConnection(). Try changing the above line to:

Properties props = new java.util.Properties();

Does that help?

New to Derby: Modifying Single User App to Server/Client

2009-11-23T10:12:53Z

I'm attempting to modify a Java desktop application (with embedded Derby) into a server/client configuration and I'm having trouble getting the client to connect to the server. I've been trying to follow the examples in SimpleNetworkServerSample.java and SimpleNetworkClientSample.java but since I'm new to both networking and Derby, I'm not sure I'm doing it correctly. For testing, I created an executable for the server and am running the client from Eclipse 3.4. I'm using Derby 10.5.3.

When I start the server, it appears to be working correctly.
======================
Server Code:
try {
NetworkServerControl server = new NetworkServerControl (InetAddress.getByName("localhost"),1527);
server.start(null);
} catch (Exception e){

}

========================
Client Code:

Properties props = System.getProperties();
props.put("derby.system.home", "C:/Apache/");
props.put("user", "user");
props.put("password", "pw");

try {
Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/MyDatabase",props);
} catch(SQLException ex) {
System.out.println("\n ------- SQL Exception");
while (ex != null) {
System.out.println("Message: " + ex.getMessage()+ex);
System.out.println("Error Code: " + ex.getErrorCode());
ex = ex.getNextException();
System.out.println("");
}
}

When I try to connect, I get the error below. This is just a sampling of the error (the actual error is very long):

------- SQL Exception
Message: A connection could not be established because the database name 'MyDatabase;java.runtime.name=Java(TM) SE Runtime Environment;sun.boot.library.path=C:\Program Files\Java\jre1.6.0_05\bin;java.vm.version=10.0-b19;java.vm.vendor=Sun Microsystems Inc.;java.vendor.url=http://java.sun.com/;path.separator=;;java.vm.name=Java HotSpot(TM) Client VM;file.encoding.pkg=sun.io;user.country=US;sun.java.launcher=SUN_STANDARD;sun.os.patch.level=Service Pack 3;java.vm.specification.name=Java Virtual Machine Specification;
...
is larger than the maximum length allowed by the network protocol.
Error Code: 40000
=========================

I did a test case where I didn't start the server, ran the client code and got a "server not found" error.

Thanks in advance,

Carol

Re: using XmlTreeWalker

2009-11-23T08:44:55Z

Hi Flavio,

I think that the AST you prefer would be equivalent to what the parser
actually does. Both representations give the compiler the information
which it needs for the tricky, later phases of rewriting the AST--the
compiler considers many re-writes when it tries to optimize the
execution of the subquery. Note that an IN list is much simpler than a
subquery and the compiler has fewer options for re-arranging an IN list
than a subquery.

I'm going on vacation now. Please don't be put off by my radio silence
for the next week.

Cheers,
-Rick

AW: AW: OOM with millions of weakly-referenced Derby objects

2009-11-23T01:55:30Z

Yes this is the API I am reffering to.
Well actually it says that, but in my case it did not do it.
It needed a long time, several minutes. Reason as it turned later out, after getting the output in a file a lot of IOExcceptions. I never got those on windows nor on Solaris. Thr original logic of the routine calling the runScript Method was asking for the return code but either it never hit this if statement and crashed somewhere within ij without giving the Exception to the caller or ij gave something like 0 so the output never was given to the logger.
So there is something phony with ij.runScript using it with AIX 5.3 and a SQL-Script not coded UTF8 but declaring in the parameters as UTF8. Of course that is a fault by my own, but it should tel me about it.

Is this the API signature you are referring to?

http://db.apache.org/derby/docs/10.5/publishedapi/jdbc4/org/apache/derby/tools/ij.html#runScript(java.sql.Connection,%20java.io.InputStream,%20java.lang.String,%20java.io.OutputStream,%20java.lang.String)

It says:

Returns:
Number of SQLExceptions thrown during the execution, -1 if not
known.

If so, are you seeing 0 or -1 returned here?

using XmlTreeWalker

2009-11-22T08:05:04Z

Hi Rick (i hope you will answer to me),
i found a strange behavior in XmlTreeWalker using the "in" keyword connected
to a select ;
look at the following sql string :
"update eurofile.tdepro set dpcdpr = ?, dpcdst = 'T', dpcdme = ? where
dpcoti = ? and dpprsk = 0 and dpflag in(select aatipo from eurofile.tabtipo
where aatipo = ?)"
i thought that the "dpflag" field should not be inside a subquery while
running XmlTreeWalker it is. Am i wrong ?
I tried with a "in" connected to constant fields and the result is as i
expected.
Can you give me a hint ?
Thanks a lot.
Flavio
ps below are both examples.

Re: Derby 10.5.3: subquery performance using "IN"

Does it help if you first SELECT the inner rows into a temporary
table, and then do a SELECT * from that tmp table in the IN subquery?

If you're looking for a transaction aware connection pool, along with
associated JTA transaction manager, I really like Bitronix (open
source). C3P0 is not transaction aware.

Is this the API signature you are referring to?

http://db.apache.org/derby/docs/10.5/publishedapi/jdbc4/org/apache/derby/tools/ij.html#runScript(java.sql.Connection,%20java.io.InputStream,%20java.lang.String,%20java.io.OutputStream,%20java.lang.String)

It says:

Returns:
Number of SQLExceptions thrown during the execution, -1 if not
known.

If so, are you seeing 0 or -1 returned here?

AW: OOM with millions of weakly-referenced Derby objects

2009-11-20T04:04:11Z

Hi to all again,

I could analyse and solve the problem.

Originally I thought that if ij findes something phony it would give a return code as its signature suggests it.

Actually after finding out that the trouble stays somehow within ij after minutes of processing and that I have to set another IO-Stream and put it out I found exceptions-traces like this

That gave me the Idea that the sql-script I am trying to play on the database is probably not UTF-8.

And .. voilà … after converting this script into UTF-8 all works fine, finally.

There are 2 things to learn about.

IJ seems not work with problems as I would aspect it as normal user, intuitively there should be either an exception or a returncode that tells you that something is going wrong instead of producing 5 mb ouput for a 3 kb script in my case.
here is obviously an os-specific java behaviour (or may be its just the behaviour of the different JVM) on how to read text files since the very same sql-script worked on Solaris and Windows with a Sun-JVM (JDK 5) that seems to be a bit more tolerant.

In other words I would count that situation as not nice behaviour of ij, since the return code should have been given as I would suppose it looking at the method signature.

Betreff: AW: OOM with millions of weakly-referenced Derby objects

Hi to all,

I have somehow a problem using derby on AIX 5.3

Derby is used as embedded DB by a little program. The database is constructed when it is not there using the specific driver property. That seems to work. Then I am using ij to create the tables etc if the first statement crashes because of having not table. This strategy works perfectly on Windows and Sun-Solaris as well, but now I am facing trouble on an AIX-machine.

Following program method uses ij

private void runScript(String fileName) throws FileNotFoundException, UnsupportedEncodingException, IOException, SQLException

{

BufferedInputStream iStream = null;

PrintStream pStream = null;

try

{

FileInputStream fileStream = new FileInputStream(fileName);

iStream = new BufferedInputStream(fileStream);

ByteArrayOutputStream bOut = new ByteArrayOutputStream(512);

pStream = new PrintStream(bOut);

logger.info("running Script '"+fileName+"'");

int result = ij.runScript(m_conn, iStream, "UTF-8", pStream, "UTF-8");

logger.debug("Result code is: " + result);

pStream.flush();

if (result!=0)

{

logger.error(bOut.toString());

throw new RuntimeException("problems running "+fileName+" rc:"+result+"\n see logs for more information");

}

finally

{

if (pStream!=null)

{

pStream.close();

}

if (iStream!=null)

{

iStream.close();

}

Obviously concerning the logs ij is called as in this line

int result = ij.runScript(m_conn, iStream, "UTF-8", pStream, "UTF-8");

after several minutes the program seems to crash without any exception I could see the derby.log got following entries (I usually expect

but does not show any of ij as it does when I use it on Window or Solaris)

following JVM is used on our AIX 5.3:

$ /usr/java5_64/bin/java –version

java version "1.5.0"

Java(TM) 2 Runtime Environment, Standard Edition (build pap64dev-20061003a (SR3))

IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc64-64 j9vmap6423-20061003 (JIT enabled)

J9VM - 20060915_08260_BHdSMr

JIT - 20060908_1811_r8

GC - 20060906_AA)

JCL - 20061003

Questions:

1. have derby and ij ever run successfully on AIX (e.g. 5.3) with Java5 (64 bit)?

2. is there a possibility to activate logs from ij so we can better see what is happening?

3. Did anybody face a similar problem and maybe got a workaround?

Thanks in advance

If running in embedded mode then don't worry too much about it. If in server

Hi Malte,

I'm changing the subject of this thread (I couldn't find it again
because you tacked it onto (hijacked) a message about an OOM error.)

1. I've tested ij and found it works - I've run the derby functional
tests some of which do run ij.runScript, and activating
org.apache.derby.tools.ij manually, on AIX with IBM 1.5.
But on my machine, although the CPU is 64 bit, the AIX Kernel is 32 bit.
I've most recently run with IBM 1.5. SR9 ( and there's now SR10 out) -
also for 32 bit, of course.

2. ij or any other derby tool will start logging when there's any
connection to a database. Judging from your actual log, it seems the
program, and logging, *is* getting started.
There is an error that occurs both in your expected log and the actual log:
delete from MEMO_RECORDS
2009-11-19 11:32:25.127 GMT Thread[main,5,main] (XID = 145),
(SESSIONID = 1), (DATABASE = DB), (DRDAID = null), Error compiling
prepared statement: delete from MEMO_RECORDS where TMPST_IN < ? :End
prepared statement
I'm not sure why, do you have an explanation for this?

One way to get more info out of derby/ij is to create a simple text
file called "derby.properties" (or modify it if you have one already)
in the dir where you start your program from and add the following:
derby.infolog.append=true
derby.language.logStatementText=true
derby.stream.error.logSeverity=0

Note, in the code snippet I see you're doing a try/finally - but I
don't see a catch of any exception. I wonder what's happening in the
method that's calling this - are you catching any exceptions there? A
printStackTrace() might be able to shed some light.

3. I've never heard of this particular problem. But problems do occur.
It's also possible there's something wrong with that particular jvm
version also. If you can get a simple repro together I can try it out
on my machine...

Since you are stopping the SQL interpreter after the parsing phase, the

AllResultColumn node does not belong to any table. Consider the
following query:

select * from s, t

The parser turns the * into an AllResultColumn node. The AllResultColumn
node can't be assigned to either table--it actually applies to both of
them. It is only during the name-binding phase that the interpreter
expands the AllResultColumn node into columns for each of the tables. I
am attaching xml showing the shape of the AST for this query after all 3
major compilation phases: parsing, binding, and optimization. You can
ignore the last 3 query trees in this file. They correspond to another
query (the procedure call which tidies up and closes the xml output).

Hope this helps,
-Rick

Performance Problems: Derby & Hibernate - Update of many entries in a table with foreign key constraints

2009-11-19T09:25:25Z

Hi there,

I'm using Derby and Hibernate (coupled to EMF & Teneo) in an Eclipse rich
client application. The Derby version is 10.5.3.0, the Hibernate tools
version is 3.2.4.GA-R200905070146-H18.

My application implements a synchronization mechanism, which pulls Objects
off a Webservice. There are master data objects which need to be completely
synchronized every time because there are no version or change information
available. This results in a lot of updated rows in the tables.

Upon saving the Hibernate EMF resource, the program grinds to a halt in the
following place:
Thread [ModalContext] (Suspended)
UpdateResultSet.foundRow(ExecRow, int[], TemporaryRowHolderImpl)
line: 1013
UpdateResultSet.runChecker(boolean) line: 975
UpdateResultSet.open() line: 264
GenericPreparedStatement.executeStmt(Activation, boolean, long)
line: 416
GenericPreparedStatement.execute(Activation, long) line: 297

EmbedPreparedStatement30(EmbedStatement).executeStatement(Activation,
boolean, boolean) line: 1235

EmbedPreparedStatement30(EmbedPreparedStatement).executeStatement(Activation
, boolean, boolean) line: 1675
EmbedPreparedStatement30(EmbedPreparedStatement).executeUpdate()
line: 302
NonBatchingBatcher.addToBatch(Expectation) line: 23

CollectionUpdateAction.execute() line: 41
ActionQueue.execute(Executable) line: 250
ActionQueue.executeActions(List) line: 234
ActionQueue.executeActions() line: 144

DefaultFlushEventListener(AbstractFlushingEventListener).performExecutions(E
ventSource) line: 298
DefaultFlushEventListener.onFlush(FlushEvent) line: 27
SessionImpl.flush() line: 1000
HbSessionWrapper.flush() line: 171
HibernateResource.saveResource(Map<?,?>) line: 375
HibernateResource(StoreResource).save(Map<?,?>) line: 430
SynchronizationWizard$1.run(IProgressMonitor) line:
ModalContext$ModalContextThread.run() line: 121

There are two nested while loos in runChecker and foundRow which iterate
over the same data. One call of foundRow takes about 3 seconds. The result
sets contain >2000 elements as far as I can see.

Is there any way to disable these checks or to make them faster (ie utilize
the index on the primary key of the table)?

Kind Regards,

Josef

Hi to all,

I have somehow a problem using derby on AIX 5.3

Following program method uses ij

BufferedInputStream iStream = null;

PrintStream pStream = null;

try

{

FileInputStream fileStream = new FileInputStream(fileName);

iStream = new BufferedInputStream(fileStream);

ByteArrayOutputStream bOut = new ByteArrayOutputStream(512);

pStream = new PrintStream(bOut);

logger.info("running Script '"+fileName+"'");

int result = ij.runScript(m_conn, iStream, "UTF-8", pStream, "UTF-8");

logger.debug("Result code is: " + result);

pStream.flush();

if (result!=0)

{

logger.error(bOut.toString());

throw new RuntimeException("problems running "+fileName+" rc:"+result+"\n see logs for more information");

}

finally

{

if (pStream!=null)

{

pStream.close();

}

if (iStream!=null)

{

iStream.close();

}

Obviously concerning the logs ij is called as in this line

int result = ij.runScript(m_conn, iStream, "UTF-8", pStream, "UTF-8");

after several minutes the program seems to crash without any exception I could see the derby.log got following entries (I usually expect

but does not show any of ij as it does when I use it on Window or Solaris)

following JVM is used on our AIX 5.3:

$ /usr/java5_64/bin/java –version

java version "1.5.0"

Java(TM) 2 Runtime Environment, Standard Edition (build pap64dev-20061003a (SR3))

IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc64-64 j9vmap6423-20061003 (JIT enabled)

J9VM - 20060915_08260_BHdSMr

JIT - 20060908_1811_r8

GC - 20060906_AA)

JCL - 20061003

Questions:

1. have derby and ij ever run successfully on AIX (e.g. 5.3) with Java5 (64 bit)?

2. is there a possibility to activate logs from ij so we can better see what is happening?

3. Did anybody face a similar problem and maybe got a workaround?

Thanks in advance

Hi Steve,

I don't know what's wrong exactly. [1] describes how to work with a
Derby database in general in NetBeans.
However, to use Derby in a project I think you have to add it as a
library yourself and then add that library to the project. Simply adding
derby.jar to the project should also work (but see my comment further
down regarding the driver).

I know there was some changes / issues when going from 6.5 to 6.7, but I
thought that was for the client driver only.

With Java SE 6 the driver would normally be auto-loaded, but I'm not
sure if that happens in an IDE (i.e. due to classloader issues).
Are you already calling
Class.forName("org.apache.derby.jdbc.EmbeddedDriver")* before you try to
obtain the connection through DriverManager?

* You may want to add .newInstance() here. This is normally only
required if the engine is unloaded by doing a Derby system shutdown.

This sounds like a great next step, please let us know what you find.

As another useful step, you could run that command using the Derby "ij"
tool, and set derby.language.logQueryPlan=true, and then post the
query plan information from your derby.log.

thanks,

EmbeddedDriver is not a library, it is a class.

Can you post your code? That would make it easier to see what you are doing wrong.

Can you compare your code against the Derby embedded example program in
demo/programs/workingwithderby/WwdEmbedded.java
(http://db.apache.org/derby/docs/10.5/getstart/rwwdactivity3.html#rwwdactivity3)

If there are sections of that web page that are confusing, ask some questions
about the confusing parts and we'll be glad to help!

thanks,

bryan

RE: OOM with millions of weakly-referenced Derby objects

2009-11-18T13:25:03Z

Kristian,

The query is approximately this:

SELECT * FROM t WHERE (some criteria) ORDER BY y;

'y' is defined as a foreign key so has an index generated. Could it be that Derby is bringing the rows internal to do the sorting?

As for maximum page cache size, it’s the default. Is there a good reference for Derby performance tuning, because I sure could use some help with that. It is currently being run as an embedded server with vm parameters -Xmx256m.

I will attempt running the command via ODBC directly, with the FETCH syntax, and produce a heap histogram (is there anything in particular you are looking for or a specific tool output -- I generally use jprofiler).

Thanks so much for your help!
Eric

Hi,

Derby now supports the OFFSET/FETCH clause. See [1] for some examples,
or consult the reference manual. I think some work is also being done on
improving the ROW_NUMBER implementation.
Regarding your OOM, that is generally not to be expected. However, it is
hard to say if it's a Derby bug without knowing what is going on in your
application, and how Derby is configured.

For instance, what is your maximum page cache size set to, and what size
is the heap of the JVM?
Posting the heap histogram might give us some clues.
Have you tried reproducing this without iBATIS?

java.sql.SQLException: No suitable driver found for jdbc:derby:jdbcDemoDB;create=true

2009-11-18T13:20:14Z

I just started using Derby. I am using NetBeans 6.7.1 with JDK 1.6.0_17. I have included Derby.jar in my IDE libraries however the system does not seem to be able to find the embedded driver. I cannot find a library called "Embedded Driver". Can anyone see what I am doing wrong? I have checked the FAQs to no avail.

Many thanks,

Steve

using ASTParser and TreeWalker

2009-11-18T09:24:28Z

Hi Rick,

i wrote some little classes trying to interpret the data provided by
XmlTreeWalker, when used with insert statement.

I'm happy to attach them, hoping somebody could find them useful or improve
them.

I found really hard to figure out the sequence of the nodes, to get the
infos i need, regarding the different sintax of the statement.

I've tested (successfully for me) with some use cases inserted in the class
MyTreeWalker, but i think there are many of them i've not imagined.

One question : how can i find the table owner of the AllResultColumn node ?

Any suggestion would be appreciated.

Flavio

Hi,

Derby now supports the OFFSET/FETCH clause. See [1] for some examples,
or consult the reference manual. I think some work is also being done on
improving the ROW_NUMBER implementation.
Regarding your OOM, that is generally not to be expected. However, it is
hard to say if it's a Derby bug without knowing what is going on in your
application, and how Derby is configured.

For instance, what is your maximum page cache size set to, and what size
is the heap of the JVM?
Posting the heap histogram might give us some clues.
Have you tried reproducing this without iBATIS?

Re: OOM with millions of weakly-referenced Derby objects

The expected behavior is really dependent upon the underlying JDBC driver.

Using the maxRows parameter is a last resort option, IMO.

Limit the results with the SQL if at all possible, here's an example:

OOM with millions of weakly-referenced Derby objects

2009-11-17T10:39:56Z

All,

I have a Derby table with up to a million rows. Some large subset of those rows may be returned by a SELECT query.

I am using IBATIS quertyForList with the embedded Derby driver. I am using the version which has a maxRows parameter. I call that method and receive back the proper “maxRows” java.sql.ResultSet objects. For example, the select would match 100,000 rows, but I only get the first 200. That all works fine.

However, I am getting OOM’s when the select would match nearly a million rows and after profiling with JProfiler the culprit seems to be millions of weakly referenced org.apache.derby.iapi.types.SQL objects (SQLLongInt, for example) that appear to be created far faster than they can be GC’ed. This particular performance test run would return a million records, of which I am only wanting to retrieve the first 200.

My questions are:

1. Is this expected behavior?

2. Is IBATIS properly using a cursor, or what is the right way to limit the number of Derby objects created (the ResultSet count is correct)

3. Are there Derby or IBATIS parameters that can be employed to correct this behavior?

Derby version is 10.5.3, IBATIS version is 2.3.4.726, and Java version is 1.6. I have cross-posted to both the Derby and IBATIS lists since I don’t know where the root problem resides.

Thanks so much for your help!

Best Regards,

Eric

I just compared the query using "IN" and "EXISTS".
The original "IN" query took a total of 5.244 sec to complete.
The "EXISTS" query took a whopping 305.567 sec to complete!

Thanks for the suggestion, but I don't think that's gonna be an option.

Any other ideas?

Is it possible that this has nothing to do with Derby, but is instead
some other behavior on your app or system?

Since Derby is just running as ordinary Java code in your JVM, it can
be affected by starvation of resources if for whatever reason your
application or system is busy.

If the overall query plan is basically identical between the "bad" run
and the "good" run (same overall query plan, same number of records/pages
touched, etc.), then perhaps when you get the slow runs, the reason is
that some other Java code in your application is stealing all the CPU
time, or some other process running on your system is stealing all the resources.

Try hooking up a tool like VisualVM to your application while it's running,
and see if you can see any differences in overall JVM behavior between
the slow runs and the fast runs.

thanks,

bryan

Thank you guys for your response.
Didn't mention earlier, I am running Derby 10.5.5 as an embedded DB.

That would be derby.storage.pageSize. Increasing the page size will
allow more records to fit onto a single page. Normally you would also
make sure the page cache is large enough to fit the most commonly used
pages, otherwise Derby will have to swap pages in and out of the cache a
lot.

derby.storage.pageSize is set before you issue 'CREATE TABLE/INDEX' statement, correct?
Also, if my table (initially set with 8KB size) grows (more row inserts) then does the file size grows? Or a derby file is added for this table of size 8KB, if so then can I change this setting and increase the size to 32KB?

What exactly do you mean with the first time?
The very first time you execute the query?
If so, and you shut down the JVM in between, the following have to
happen the very first time you run a query:
- load all the Derby classes (this is a significant number)
- compile the SQL query (i.e. parsing, binding, optimization, code
generation)
- fetch all data from disk (the caches are empty)
- to get optimal performance, you must run the queries enough time to
allow Java HotSpot to optimize them

Assuming you have run the application for a while and the caches are
warmed up, you don't have to do any of those steps.

Besides from the factors above, I would investigate the query plans as
Bryan mentioned.

Sorry for the certain level of obscurity in my question. I will re-frame my question.
I run my app on an embedded Derby DB. Closing and starting the app. implies to closing and starting JVM.
For example, this morning I started my app and did few 'app stuff', the queries took much longer. I closed my app/JVM, started again and did the exact same 'app stuff', and the queries were much faster.

P.S. I compared the Query Plans, and they are the same moreover because i am overwriting the Query Plan for Indexes and Joins (has been very helpful in my case).

Does this implies that between the first and second app/jvm start and shutdown the indexes in file are optimized, files compressed? Couldn't find answer to what exactly happens.

The weird part - for the whole day I will not have that slow query issues until next day morning. I don't shutdown my system.

> Q4) Calling CALL SYSCS_UTIL.SYSCS_COMPRESS_TABLE(?, ?, ?) right after the

Again, just the very first time or for an extended period of time after
you have compressed the table?

I start my app, call compress table and then until i close down my app/JVM all the qureies take longer to execute. The next time I start my app the same queries are much faster.
