Error description
You have four transactions in a dead lock. Three of the transactions are waiting to obtain the JVMSRVLK lock and the other transaction is waiting to obtain the STLOCK. The owner of the STLOCK is a transaction without a TCA and is currently suspended in an LMQUEUE waiting to obtain the SJGLOBAL lock. The transaction owner of both the JVMSRVLK and SJGLOBAL locks is currently dispatchable waiting to run on T8 TCB. So why is this task unable to run on the T8 TCB for so long? Well the JVM and associated LE enclave have terminated but CICS still thinks that the JVMSERVER is enabled and that the T8 TCB is able to be used. The root of the problem is why the JVM went away.

Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: JVMSERVER becomes unresponsive after * * initial pthread TCB ( IPT ) abends * * unexpectedly. * **************************************************************** * RECOMMENDATION: * **************************************************************** The initial pthread TCB for a JVMSERVER is unexpectedly abended. CICS has no recovery environment to intercept the abend of this TCB so no diagnostic message or dump information is produced.
Problem conclusion
The JVM server initialisation module DFHSJPTI has been changed to establish an ESTAE exit when a JVMSERVER is installed and enabled. If the ESTAE exit is driven due to an unexpected abend of the initial pthread TCB, new message DFHSJ0005 is issued to report the error. DFHSJPTI will then attempt to take a system dump with dump code KERNDUMP. Diagnostic information from the SDWA will be saved into new pointers anchored from the sj_kernel_ipt_data block. The CICS Transaction Server for z/OS Version 5 Release 1 CICS Messages and Codes Vol 2 ( GC34286200 ) will be updated. In Chapter 4, new message DFHSJ0005 will be added as follows :- DFHSJ0005 APPLID AN UNEXPECTED ABEND HAS OCCURRED ON THE INITIAL PTHREAD TCB FOR JVMSERVER: JVMSERVER EXPLANATION: The initial pthread TCB for JVMSERVER resource jvmserver has abended unexpectedly. SYSTEM ACTION: CICS attempts to take a system dump with dumpcode KERNDUMP. USER RESPONSE: The JVMSERVER resource jvmserver will become unresponsive and it will not be possible to restart it. You should cancel CICS if you cannot run without the JVM server. NOTE: This message cannot be changed with the message editing utility. DESTINATION: Console MODULE: DFHSJPTI The CICS Transaction Server for z/OS Version 5 Release 2 CICS Messages and Codes Vol 2 ( GC34728400 ) will be updated. In Chapter 4, new message DFHSJ0005 will be added as follows :- DFHSJ0005 APPLID AN UNEXPECTED ABEND HAS OCCURRED ON THE INITIAL PTHREAD TCB FOR JVMSERVER: JVMSERVER EXPLANATION: The initial pthread TCB for JVMSERVER resource jvmserver has abended unexpectedly.
