CICS JVMServer stuck in ENABLING state with CEMT Enablestatus Disabled

Question & Answer


Question

Why would a JVMServer get stuck in an ENABLING state when I try to install it in my CICS Transaction Server for z/OS (CICS TS) region. A CEMT INQ JVMServer command shows "Enablestatus( Disabled )".

I checked the various places for JVMServer errors and cannot find anything indicating what could be causing the JVM to stall. During CICS startup, the region issues message "DFHSJ0102I SJ domain initialization has ended". Regarding the JVMSERVER the only message I have found is :

DFHSJ0910 01/22/2017 04:54:06 CICSCTCA CICSCTCA JVMSERVER CTCJVM has been created. There is nothing after that in the region or in the workdir in zfs.

The SJ domain in the system dump of the CICS regions shows a State of "enabling":

 ==SJ: JVM SJ JVMSERVER SUMMARY     
 JCB number installed : 00000001    MAXTHRDTCBS :  00000010     
  SJ JSR fields 
     JVMSERVER Name      : CTCJVM              JVM Process ID      : 00000000          
     LE Runtime Options  : DFHAXRO             JVM Profile         : HBRJVM            
     State               : enabling         

Here is the output from CEMT INQ JVMServer:

Answer

Install CICS supplied group DFHJAVA and the status of the JVM should change to Enabled. In this case, a CEDA install of the group DFHJAVA allowed the JVM to complete initialization.
