Direct QSAM access through a CICS task-related user exit

z/OS® Debugger can use two methods to access the following types of files:
  • Enterprise COBOL and Enterprise PL/I separate debug files (SYSDEBUG)
  • C/C++ separate debug files (.dbg and .mdbg)
  • assembler and LangX COBOL EQALANGX files
  • listing and source files
  • command and preference files
  • save settings and save breakpoints and monitor specification files
  • log files
The following list describes both access methods:
  • CICS® Extrapartition Transient Data (default method)
  • Direct QSAM access through a CICS task-related user exit

If you want the access method to avoid using CICS SPI and API to access these files, enable the QSAM access method.

To enable the QSAM access method, use the following INITPARM in your CICS start up parameters: 
INITPARM=(DFHLETRU='USEQSAM')
You also need to apply the following PTFs to the appropriate products:
  • For CICS Transaction Server for z/OS, Version 3.1, apply the PTF for PK67329
  • For CICS Transaction Server for z/OS, Version 3.2, apply the PTF for PK68401
  • For Enterprise COBOL compilers, apply the PTF for PK71852 to Language Environment®, Version 1.8 through 1.10
  • For Enterprise PL/I compilers, apply the PTF for PK93564 to Language Environment, Version 1.8 through 1.11
