Hi,

Please give me purpose of the parameter “JAVA_MAX_PERM_SIZE” in server.bat file of Integration Server.

I guess this parameter is newly added in wM 7.1 ???

Thank you in advance !

Warm Regards,

It’s for the permanent generation memory space inside the JVM. Here is a good explanation of what it is used for (where all the classes basically, not the objects) - [url]http://blogs.sun.com/jonthecollector/entry/presenting_the_permanent_generation[/url]

Generally you should not have to mess with it unless webMethods recommends it to you or you are getting PermGen out of memory errors. I believe the default they are setting is 128MB instead of the default 64MB.
