Error description
Under CICS, execution time performance is increased with COBOL V6.1
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Enterprise COBOL users running programs * * that make dynamic calls between COBOL V5+ * * and pre-COBOL V5 programs under CICS. * * * **************************************************************** * PROBLEM DESCRIPTION: Run time Performance: When running * * under CICS, dynamic call performance * * can be degraded for calls between V5+ * * and pre-V5 programs. The effect may be * * more noticeable when there are many * * programs involved in the transaction. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** In the COBOL runtime, various dynamic call fast path logic and call caching available under batch were not enabled when running under CICS.
Problem conclusion
Dynamic call overhead has been reduced for the following scenarios under CICS (COBOL V5+ means COBOL V5 and later programs, pre-COBOL V5 means COBOL V4 and earlier programs): - V5+ to V5+ - V5+ to pre-V5+ - pre-V5+ to V5+
