The Composite Platform Installation Tool fails on WebSphere® Application
Server because of insufficient
memory.
Symptoms
The Composite Platform Installation Tool fails on WebSphere Application
Server with error messages in
the cpit.install_std.out file when the C:\Program
Files (x86)\IBM\cpit\install-scripts\configPE.bat script
runs.
Causes
The Java Virtual Machine for WebSphere Application
Server exhausts its heap space
when the Composite Platform Installation Tool runs.
Environment
Windows
Diagnosing the problem
Review the cpit_install_stdout.txt and SystemOut.log files
for the exceptions and log entries. The java.lang.OutOfMemoryError:
Java heap space error message in the SystemOut.log file
for WebSphere Application
Server indicates
that the Java Virtual Machine ran out of heap space.
Resolving the problem
To resolve the out-of-memory error and rerun the Composite

- Increase the maximum and minimum heap sizes for the Java Virtual Machine
to the following values on the system where you ran the Composite
Platform Installation Tool:
- Initial heap size: 512 MB
- Maximum heap size: 1024 MB
- Delete the contents of the decompressed folder
to ensure that there is enough space to rerun the Composite Platform
installation Tool:
- Navigate to the C:\Program Files (x86)\IBM\cpit\decompressed folder
and delete the TDS, CE, WAS,
and WPXT subfolders.
- Empty the Recycle Bin.
- Replace the cpit.properties file:
- Delete the cpit.properties file from the cpit folder
where you ran the 5.2.1-CPIT-WIN.exe file.
- Copy the cpit.properties file from the C:\Program
Files (x86)\IBM\cpit\install-scripts folder to the cpit folder
where you ran the 5.2.1-CPIT-WIN.exe file.
- Run the 5.2.1-CPIT-WIN.exe file.
