Reducing block sizes can be *very* costly in performance. Same for buffers. Don't do that.
Technically, it is very easy to change a few compile options and recompile. And that is the better choice by far. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of JONES, CHARLIE Sent: Wednesday, November 09, 2005 12:17 PM To: [email protected] Subject: COBOL Program exhausting below the line storage Compiler: PP 5655-G53 IBM Enterprise COBOL for z/OS and OS/390 3.2.0 We have a LARGE COBOL application program that is exhausting below the line storage and abending. There are 16 QSAM files and an IDMS Database. Sub Pool 0 (File Buffers 1.5meg) and Sub Pool 2 (Working Storage 2meg) are using about 3.5meg total Are there any easy tricks to make the entire program run above the line? Or will we simply have to reduce file buffer sizes (Blocking Factor) and reduce Working Storage array sizes?
