SUP_SYSTEM_SYMBOL_TABLE_SIZE

Description:

Checks to see whether the size of the static system symbol table has exceeded the threshold. The check is initially run once and is also run when the SETLOAD xx,IEASYM command is successfully processed.

Reason for check:

Monitor the size of the system symbol table.

z/OS® releases the check applies to:

z/OS V2R1 and higher.

Type of check (local or remote):

Local

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Parameters accepted:

LIMIT( {n | p%} ) which defines a threshold value. The value of n may be a decimal number in the range 1 to 57088. The value of p% identifies a percentage p in the range 1 to 100, from which the system calculates the threshold value, based on the system maximum symbol table size of 57088 bytes.

Output:

Example of success message:

IEAVEH110I The system symbol table size is 264 bytes. This has not
exceeded the installation-specified threshold of 264 bytes. 
The maximum size is 57088 bytes.

Example of exception message:

IEAVEH111E The system symbol table size is 268 bytes. 
The installation-specified threshold of 264 bytes has been exceeded.         
The maximum size is 57088 bytes.                                   
                                                                     
  Explanation:  The check determined
    that the system symbol table size has exceeded the                
    installation-specified threshold.                                
                                                                     
  System Action:  The system continues processing.

  System Programmer Response:  If you think you will need to add     
    additional symbols in the future, see if you can consolidate or  
    eliminate ones that already are defined.
