The Composite Platform Installation Tool fails with an out-of-memory error

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 Platform Installation Tool, complete the following steps:
  1. 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
  2. Delete the contents of the decompressed folder to ensure that there is enough space to rerun the Composite Platform installation Tool:
    1. Navigate to the C:\Program Files (x86)\IBM\cpit\decompressed folder and delete the TDS, CE, WAS, and WPXT subfolders.
    2. Empty the Recycle Bin.
  3. Replace the cpit.properties file:
    1. Delete the cpit.properties file from the cpit folder where you ran the 5.2.1-CPIT-WIN.exe file.
    2. 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.
  4. Run the 5.2.1-CPIT-WIN.exe file.
