Error description
Error Description After upgrading to CICS TS 4.2. during shutdown you get message DFHFC0002 A severe error (code X'0435') has occurred in module DFHFCST (base). What is happening is DFHFCST, File Control Statistics Program, is collecting statistics for the LSRPOOL's. It is going through all 255 LSRPOOLs. When it gets to POOL_ID(FF) it is getting an error of SHRCTL_BLOCK_NOT_FOUND. In the CICS internal trace table you see: AP 0430 FCST ENTRY - FUNCTION(COLLECT_POOL_STATISTICS) POOL_ID(FF) AP 0435 FCST *EXC* - DISASTER DETECTED FUNCTION(COLLECT_POOL_STATISTICS) REASON(SHRCTL_BLOCK_NOT_FOUND) Prior to CICS TS 4.2 CICS only used LSRPOOLs 1-9, now at CICS TS 4.2 CICS may use all 255 LSRPOOLS.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: On shutdown CICS issues the following * * message: DFHFC0002 A severe error (code * * X'0435') has occurred in module * * DFHFCST. * **************************************************************** * RECOMMENDATION: * **************************************************************** A program is run within CICS which accesses a file using an LSRPOOL, but it does so without using CICS File Control. CICS is then shutdown, during which DFHFCST is driven to gather statistics on all LSRPOOLs. DFHFCST checks for a VSAM Shared Resource Table (VSRT) for each LSRPOOL ID. The LSRPOOL used by the program has been built, so the VSRT pointer is non-zero. Procesing continues and DFHFCST attempts to establish addressability to the SHRCTL block for this LSRPOOL. However as CICS File Control has not used this LSRPOOL the block doesn't exist and a disaster response is returned. This escalates and the error message is issued despite the fact that no erroneous events have occurred. ADDITIONAL KEYWORDS: msgDFHFC0002 msgFC0002 FC0002
Problem conclusion
DFHFCST has been modified so that in the previously described scenario a new exception type is returned. No action is taken based on this response and therefore no error message is issued.
