Troubleshooting
Problem
The MVS LOAD of a program object from a PDSE data set fails with RC24 RSN2708043D. The failure can occur in any batch job or started task in an environment running CA-Program Manager Optimizer Release 4.4 (CA-PMO for OS/390) with the product's DESERV EXIT implemented
Symptom
Repeated CSV031I LIBRARY SEARCH FAILED FOR MODULE xxxxxxxx, RETURN CODE 24, REASON CODE 2708043D, DDNAME yyyyyyy.
RSN2708043D translates to DESRS_CONNID_OVERFLOW and it is an indication that 65,536 connection identifiers are allocated and a request to add another connection identifier failed.
This reason code does not generate a system software LOGREC error, nor is an SVC dump taken for the reason code.
Cause
A DESERV exit in the CA-Program Manager Optimizer Release 4.4 (CA-PMO for OS/390) is issuing a BLDL macro calls without the NOCONNECT parameter.
The failure to specify the NOCONNECT BLDL option results in an increasing number of connections and eventually the CSV031I LIBRARY SEARCH FAILED RC24 and RSN2708043D message.
Environment
Running CA-Program Manager Optimizer Release 4.4 (CA-PMO for OS/390).
Diagnosing The Problem
- Running CA-Program Manager Optimizer Release 4.4 (CA-PMO for OS/390) with the DESERV EXIT implemented
- Repeated CSV031I LIBRARY SEARCH FAILED FOR MODULE xxxxxxxx, RETURN CODE 24, REASON CODE 2708043D, DDNAME yyyyyyy being issued for an executing task.
Resolving The Problem
- A temporary circumvention is to add the following DD statement to the task that is incurring the failure:
//PMONODSV DD DUMMY
Including this DD statement disables the PMO DESERV exit. - A second temporary circumvention is to stop and restart the affected initiator, WLM stored procedure or started task. This action closes and releases PDSE member connections from the task.
- Contact Computer Associates for a permanent resolution.
