Issue/Introduction

I am getting a coupling facility error message IXC585E even though I have CA ACF2 set higher.  Why?

 

 

 

Environment

Release:
Component: ACF2MS

Resolution

This document describes why the IXC585E message is generated even though the ACF2 GSO SYSPLEX record has FULL THRESHOLD set to a higher percentage then what the message indicates.

Sample message:

 *10.27.51 DEV   *IXC585E STRUCTURE ACF2_DEV IN COUPLING FACILITY DEV1                                                    
 *IS AT OR ABOVE STRUCTURE FULL MONITORING THRESHOLD OF  85%.  

 ACF2 GSO SYSPLEX record has FULL THRESHOLD-89%

The message is generated by z/OS processing because the threshold set in the CFRM policy when the structure was created has been reached.

Below is an excerpt of the CA ACF2 Admin Guide, page 23-4.

Pay close attention to the fact that there are two places to specify a full threshold value.

The first is when the structure is created via the CFRM policy.

The second is the FULLTHSH() field in the GSO SYSPLEX record.

If the full threshold value in the CFRM policy is set lower than the value in the GSO SYSPLEX record, the system will always try to rebuild the structure first. If the value in the FULLTHSH() field is set lower than the full threshold specified in the CFRM policy, the action specified in the FULLACTN() field of the GSO SYSPLEX record will be executed.

The bottom line is that either the IBM parm needs to be increased to match the CA ACF2 parm, or the CA ACF2 parm lowered to match the IBM parm.
