You're welcome.
I use the notation $OTM_HOME, simply to reference the OTM install directory. This variable doesn't need to be defined within your environment for OTM to startup. So, you should be fine.
After restarting OTM, you can verify that the memory values have increased by watching the $OTM_HOME/logs/oas/console.log file. The Java GC statements should look like this:
Code:
[Full GC 1024447K->815040K(2048896K), 3.4803020 secs]
Wh
ere 2048896K is the amount of memory assigned to OAS.
