Error description
Using the default DFH0STAT program. When running the STAT transaction. This completes fine, and produces the reports fine, however there is also an abend0c4 pic11 taken in DFHDSWR at offset + x'0868', when the following set of options are used: - CICS region is started with SIT override TCPIP=NO - STAT transaction, statistics panel's Report Selection has TCP/IP set to Y. In this case a couple of dumps are taken similar to the following: DUMP TITLE=CICS DUMP: SYSTEM=appl-id CODE=DS0002 ID=2/0001 +DFHDU0202 appl-id SDUMPX COMPLETE. SDUMPX RETURN CODE X'00' +DFHDS0001 appl-id An abend (code 0C4/AKEA) has occurred at offset X'0868' in module DFHDSWR. . DUMP TITLE=CICS DUMP: SYSTEM=appl-id CODE=DS0001 ID=2/0002 +DFHDU0202 IYCKZCDK SDUMPX COMPLETE. SDUMPX RETURN CODE X'00' . Then the dump with code=DS0002 shows Kernel stack entry for the STAT transaction with similar to: . DFHEIQMS DFHSOST COLLECT_RESOURCE_STATISTICS DFHDSWR INQ_RESOURCE SEVERE_ERROR . A CICS internal trace taken, shows the abend occurred while collecting resource statistics for resource type TCPIP, followed by an invalid token got back for an INQ_RESOURCE. . ..QR SO 0A01 SOST ENTRY COLLECT_RESOURCE_STATS RESOURCE_TYPE(TCPIP) RESOURCE_STATISTICS_DATA.. ..QR DS 1100 DSWR ENTRY INQ_RESOURCE RESOURCE_NAME(S8TLSHS) TOKEN(00000000 , 00000000) [[[[[[[[[[[[[[[[[[[ ..QR DS 110A DSAC *EXC* INVALID_TOKEN FUNCTION(INQ_RESOURCE) RESOURCE_NAME(S8TLSHS) TOKEN(00000000 , 00000000) (This is the DSWR token). Additional symptoms: During shutdown of your region, you receive the following error: DFHDS0002 A severe error (code X'110A') has occurred in module DFHDSWR In the dump Module DFH0STPR + X'6D06' has issued EXEC CICS EXTRACT STATISTICS. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: STAT transaction, EXTRACT STATISTICS * * TCPIP and COLLECT STATISTICS TCPIP * * abend with messages DFHDS0002 and * * DFHDS0001 when SIT override TCPIP=NO. * **************************************************************** CICS region was started with SIT override TCPIP=NO but STAT transaction, statistics panel's Report Selection has TCP/IP set to Y. The statistics report was printed for TCP/IP as a result, but with the uninitialized values in the TCP/IP SSL handshake fields. Abend can be observed with commands EXTRACT STATISTICS TCPIP and COLLECT STATISTICS TCPIP, when SIT override TCPIP=NO. Abend messages DFHDS0002 and DFHDS0001 were printed in job log while collecting resource statistics for TCP/IP.
Problem conclusion
CICS has been changed to populate the TCP/IP SSL handshake fields with zeroes when SIT override TCPIP=NO.
