Troubleshooting
Problem
Attempts to install IBM Rational Application Developer for WebSphere Software or other Rational Software Delivery Platform products result in the error "JVMJ9VM015W Initialization error for library j9gc24(2)".
Symptom
Steps to reproduce:
- Install IBM Installation Manager (IM) 1.2.x or later.
- Install IBM Rational Application Developer for WebSphere Software v7.5.x
IBM Java Virtual Machine (JVM) displays following error:Could not create the Java virtual machine.
The IM log shows:
Error: JVMJ9VM015W Initialization error for library j9gc24(2): Failed to instantiate heap; 1G requested
Cause
Unknown
Environment
Comodo Firewall, Citrix, and other security software installed.
Diagnosing The Problem
To verify that the issue occurs with all Java applications that request 1GB of RAM or more, run the following command from the command prompt.
java -Xmx1024m
and javaw -Xmx1024m
To find the root cause of this issue, determine which product on your system blocks the JVM's request for 1GB of memory. See the Related Information section.
After finding the non-IBM product that might cause the problem, contact that product's support team to address this issue.
Resolving The Problem
WORKAROUND:
- Disable the Eclipse initialize process/change the heap size:
For Installation Manager 1.3.x, add-Dcic.doNotInitialize=true
and-Dcic.doNotReconcile=true
options to the end of ibmim.ini file.
The ibmim.ini is located in the{InstallationManagerInstallDirectory}\eclipse
directory
Note: You must modify the memory value in the files to reflect your environment settings. For example, if a system only allows a Java process to request 512 Megabytes heap size, the second line in the files must have-Xmx512m
.
- Launch Installation Manager and reinstall IBM Rational Application Developer.
- Remove eclipse.reconciler.ini and eclipse.initialize.ini from IM install location or remove
-Dcic.doNotInitialize=true
and-Dcic.doNotReconcile=true
options from ibmim.ini file.
- Open Rational Application Developer install directory; use a text editor to open the eclipse.ini file and change the -Xmx value from 1024m to 512m.
