Status: Verified
SYMPTOM(s):
Error occurring adding more agents for unified broker
Error occurred during initialization of VM Could not reserve enough space for object heap
The error keeps displaying on the screen using any unified broker management utilities
Only have free memory 117 Meg on the system
-Xmx java heap size did not change and is of default setting
FACT(s) (Environment):
WebSpeed 3.x
OpenEdge 10.x
CAUSE:
This error indicates that the JVM has not been able to acquire enough virtual memory to configure -Xmx for the setting chosen. Following are default mx settings for different version of JVM on difference platforms
Default sizes for -Xmx (maximum heap size)
* 1.4.2
* Windows: Half the real storage with a minimum of 16 M
and a maximum of 2 G
* AIX, and z/OS: 64 M
* Linux: Half the real storage with a minimum of 16 M and
a maximum of 512 M
* Solaris: 64 M
* HP-UX: 64 M
Default sizes for -Xms (minimum heap size)
* 1.2.2 and 1.3.0
* Windows: 4 M
* AIX, z/OS, Linux, Solaris: 1 M
* 1.3.1
* Windows, AIX, Linux: 4 M
* z/OS: 1 M
* Solaris: 3584k
* HP-UX: 2 M
* 1.4.1
* Windows, AIX, Linux: 4 M
* z/OS: 1 M
* Solaris: 1 M
* HP-UX: 2 M
* 1.4.2
* Windows, AIX, Linux: 4 M
* z/OS: 1 M
* Solaris: 3670k
* HP-UX: 2 M
FIX:
Add more memory to the machine so the default setting can be satisfied or
decrease Xmx setting for Java heap.
