Disabling the RMI garbage collector

Getting ready

How to do it...

To disable the RMI garbage collector, consider the following steps:

1. Navigate to the domain's bin directory:

   cd %MIDDLEWARE_HOME%/user_projects/domains/soa_domain/bin

2. Open the script setSOADomainEnv.cmd or setSOADomainEnv.sh in a text editor.

3. Locate the following line:

   SET EXTRA_JAVA_PROPERTIES=%EXTRA_JAVA_PROPERTIES% -Dums.oracle.home=%UMS_ORACLE_HOME% 

   Or the equivalent on a Linux or a Unix system.

4. Edit the previous line to add the following properties:

   • -Dsun.rmi.dgc.client.gcInterval=3600000

   • -Dsun.rmi.dgc.server.gcInterval=3600000

   SET EXTRA_JAVA_PROPERTIES=%EXTRA_JAVA_PROPERTIES...
