Error description
DFHSJ1007 JVMSERVER is being disabled and restarted by CICS because it is in an inconsistent state. JVMserver goes into inconsistent state and does not respond to CEMT SET JVM(JVMNAME) disable/enable/purge/forcepurge. At this point the JVMServer is hung and tasks involved are in a deadlock. Previous joblog messages show the following abend: DFHSJ0001 An abend (code ---/AKEA) has occurred at offset X'0C82' in module DFHSJIN Additional Symptom(s) Search Keyword(s): KIXREVCTC added new trace point 0B22 tid_sjjs_statscol_error

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: JVMSERVER cannot be re-enabled due to * * hung task holding SJGLOBAL. * **************************************************************** A request is made to collect statistics about an enabled JVMSERVER. This causes a call to be made into the JVM server to execute Java code. Whilst the Java code is executing the JVMSERVER is disabled. The logic to disable a JVMSERVER will not wait for the task collecting statistics to complete, so it is possible for the JVM to be destroyed before the Java code collecting statistics finishes. If this occurs the task collecting statistics will hang indefinitely. If execution of the statistics request went through DFHSJST, the hung task will hold the SJGLOBAL lock which will prevent JVMSERVER resource actions, such as the re-enabling of the disabled JVMSERVER.
Problem conclusion
DFHSJJS has been modified so that disabling of a JVMSERVER will wait if statistics collection is in progress.
