Issue/Introduction

Introduction: 

CA TPX manages its own storage, which eliminates the operating system overhead of GETMAIN/FREEMAIN. You can improve efficiency by specifying how it handles this storage both above and below the 16-megabyte line. The two types of storage areas it manages include:

  • Dynamic Storage Area (DSA):  Used mainly for large requests and screen images.
  • Slot Pool Storage: Series of fixed-length slots used mainly for internal control blocks.

 

Background:  

When any of the TPX slot pools overflows, a TPX300 message is written to the TPX LOG DD as well as Health Checker message TPXH3002E.

TPX can usually manage one slot overflow by using alternate slot pools for the purpose.  When multiple slot pools overflow, then TPX users can be impacted.

Crucial information to diagnose the situation are TPXOPER displays of storage below and above the line (D STOR & D STORXA).  These commands are not available for submission from the system console, only by using TPXOPER.

If users are being impacted and the TPX administrator cannot sign on to TPX, there was no way to obtain this information.

TPX 5.4 has been enhanced to eliminate the need for manual intervention in this situation.  Storage display information is automatically written to the LOG whenever a TPX300 message has been generated.  This is identified by a new message:  TPBL0300 or TPXL0300 STORAGE STATISTICS BELOW/ABOVE 16M LINE.  The storage displays follow using message id TPXSTRG.
