Hi,

Martin has helped me get this far with a large model. I now get

log4j:WARN No appenders could be found for logger
(org.eclipse.emf.teneo.hibernate.HbHelper).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

I have eclipse set top run with these parameters

D:\eclipse\eclipse.exe -vmargs -Xmx1024M -XX:PermSize=64M
-XX:MaxPermSize=128M

I am using the latest (as of Monday) version of Teneo. I notice the
process doing the work when running my Hib DataStore init (as below)
only uses 100MB. It there some way of increasing the memory available to
this process? There are over 1000 tables being generated.

There is nothing in the error log window from the time I run this.

// the name of the datastore
String hbName = "MyGenSec";
// the name of the database, this database should exist but does not
need to contain tables
String dbName = "gensechib";
// Set the database information, Environment is
org.hibernate.cfg.Environment
final Properties props = new Properties();
props.setProperty(Environment.DRIVER, "com.mysql.jdbc.Driver");
props.setProperty(Environment.USER, "root");
props.setProperty(Environment.PASS, "passw0rd");
props.setProperty(Environment.URL, "jdbc:mysql://192.168.0.3:3306/" +
dbName);
props.setProperty(Environment.DIALECT,
org.hibernate.dialect.MySQLInnoDBDialect.class.getName());
// props.setProperty(PersistenceOptions.ID_FEATURE_AS_PRIMARY_K EY,
"false");
// create the HbDataStore
HbDataStore hbds = HbHelper.INSTANCE.createRegisterDataStore(hbName);

// sets its epackages stored in this datastore
hbds.setEPackages(new EPackage[]{GensecPackage.eINSTANCE});

// set the relational database to use and other properties
// to set Teneo specific options call hbds.setPersistenceProperties
hbds.setHibernateProperties(props);

// initialize, also creates the database tables
hbds.initialize(); }

Hi,
Have you tried with a larger maxpermsize?

Hi,

Yes I tried 256M and 384M and the size of the process doing the work
remains at about 101MB until it gets that OutOfMemoryException, which
made me think the PermSize is not the issue.

What I do not get is that I know you had success ( partial at least
until MySQL threw in the towel) withthe same model?

Hi David,
I should have thought about this earlier: I am not sure how you start the test run but when you do
this from within Eclipse (like with right-mouse click run-ass) then you need to set the -Xmx setting
in the run dialog (so not in the eclipse startup). In Eclipse open the run dialog (under the run
menu), your test program should be listed somewhere, select it and in the second tab (arguments) add
the correct parameters to the VM Arguments field. Press apply and run, normally with subsequent runs
Eclipse will automatically re-use the run settings.

Hi,

I gave it -Xmx768M and watched the process as it ran it took up to 268MB
and then failed silently. Nothing in Error log either.

Still getting this

Hi David,
Are you sure that log4j.properties is copied to the output folder?
If you have a plugin project then my experience is that the log4j.properties has to be specifically
selected in the build.properties (to be part of the binary build).

What I find strange is that the console does not show an exception (as you are not mentioning it).
How do you know that the initialize step actually failed?

gr. Martin

Hi,

Firstly I was following the instructions on the EMF Hibernate
Troubleshooting page and it says :"This file should be placed directly
in the src directory of your EMF Model project." When I moved
log4j.properties to the bin directory, bingo logging worked and so did
everything else it seems so far.

It has now been running for 45 minutes, creating tables etc. I note lots
of ERROR messages in the log, will investigate these when it is done. I
also note that it produces so many log messages that the Console in
Eclipse does not respond, so will set a RollingFileAppender next time.

Thx.

David

Hi David,
Yes you need to place it in the src directory and then you need to tell Eclipse to copy it to the
bin (or build) directory when building. I have added this to the docs, will be visible in the next
release.

I also noticed a lot of errors related to index creation. Often these occur because a table was not
created or because of other database constraints.

Hi,
Have you tried with a larger maxpermsize?

Hi,

Yes I tried 256M and 384M and the size of the process doing the work
remains at about 101MB until it gets that OutOfMemoryException, which
made me think the PermSize is not the issue.

What I do not get is that I know you had success ( partial at least
until MySQL threw in the towel) withthe same model?

Hi David,
I should have thought about this earlier: I am not sure how you start the test run but when you do
this from within Eclipse (like with right-mouse click run-ass) then you need to set the -Xmx setting
in the run dialog (so not in the eclipse startup). In Eclipse open the run dialog (under the run
menu), your test program should be listed somewhere, select it and in the second tab (arguments) add
the correct parameters to the VM Arguments field. Press apply and run, normally with subsequent runs
Eclipse will automatically re-use the run settings.

Hi,

I gave it -Xmx768M and watched the process as it ran it took up to 268MB
and then failed silently. Nothing in Error log either.

Still getting this

log4j:WARN No appenders could be found for logger

log4j:WARN Please initialize the log4j system properly.

Even after adding the HbHelper to the log4j.properties in the project

Hi David,
Are you sure that log4j.properties is copied to the output folder?
If you have a plugin project then my experience is that the log4j.properties has to be specifically
selected in the build.properties (to be part of the binary build).

What I find strange is that the console does not show an exception (as you are not mentioning it).
How do you know that the initialize step actually failed?

Hi,

Firstly I was following the instructions on the EMF Hibernate
Troubleshooting page and it says :"This file should be placed directly
in the src directory of your EMF Model project." When I moved
log4j.properties to the bin directory, bingo logging worked and so did
everything else it seems so far.

It has now been running for 45 minutes, creating tables etc. I note lots
of ERROR messages in the log, will investigate these when it is done. I
also note that it produces so many log messages that the Console in
Eclipse does not respond, so will set a RollingFileAppender next time.

Thx.

David

Hi David,
Yes you need to place it in the src directory and then you need to tell Eclipse to copy it to the
bin (or build) directory when building. I have added this to the docs, will be visible in the next
release.

I also noticed a lot of errors related to index creation. Often these occur because a table was not
created or because of other database constraints.
