Maximum Heap Size in Java 5

843829Jan 12 2007 — edited Jan 12 2007
When migrating an application from JDK1.4.2_12 to JDK1.5.0_10,it was seen that the max. heap size that was set using -Xmx had to be reduced from 1.5 GB to 1.3 GB on a win32 machine inorder to create JVM successfully. Any pointers to what in Java 5.0 could have brought about this change is highly appreciated.

(Please note that I understand how heap size allocation works w.r.t virtual memory on win32.)

Please provide the following information so we can help:

What version of SQL Developer are you using?

What are the results of opening the properties for the connection and doing a test?

Does the navigation tree open correctly?

Are you having trouble with all of your Oracle connections?

When running those queries are they using the same connection as the export?

Provide the details of the NPE when using the Export Wizard.

Exactly what steps are you taking to do the export? (eg, from the Navigator/tools...)

Are there any other errors in the SQL Developer log?
