Troubleshooting Q&A

Q: What fixes are available for my installed RPE version.
Fix packs are available from IBM Fix Central. Check if there is a fix pack published for your current release.
Example: the fixpacks applicable to the RPE 1.2 release are listed here.
Check the RPE Support Page for a list of known defects and possible workarounds or hotfixes.

Q: Where can I find a list of supported operating systems ?
A: See the Systems Requirements Page. If you ever loose this link you can find it on the links section.

Q: What do the Xmx and Xms flags do in the ini ?
A: Xms specifies the amount of memory the JVM should allocate at start. I am yet to find a scenario where this is useful/required to chage from the default value.
Xmx – sets the maximum ammount of memory the JVM can use. For 32 bit processes ( Launcher/Studio) this is limited to ~1.5GB on Windows. See this for more details on how to set this value:

Q: How would a user get a log file to send to support ?
A: RPE log files are located in the %TEMP%\RPE folder. On Windows if you open Windos Explorer and put this in the address bar (%TEMP%\RPE) you will be taken to that folder where you will find a number of log files called rpe*.log.

With the default settings shipped with RPE a maximum of 5 log files is kept and each file has a maximum of 1 MB. You can change the max number of log files RPE keeps and their max size by changing the in %RPE_HOME%\config\
More information on log4j can be found here:

The official RPE Support Page from the RPE Product Page at IBM is also very useful as it contains all the technotes published by the RPE dev&support teams.
