Issue/Introduction

We are receiving the message below, all reports that can be purged have been, so what is the process to increase the size of the file queue?

ESF078    91 % FILE QUEUE UTILIZATION 

Additional symptoms in case the utilization reaches 100 %:

ESF765  JES->ESF INTERFACE - ESF FILE OPEN  FAILED, RC=01, JOBnnnnn xxxxxxxx, 
ESF769  JES->ESF INTERFACE HAS BEEN TERMINATED

 

Environment

Release : 12.0 14.0

Component : Spool

Resolution

The process to increase the size of the file queue requires a cold start so you need to create a backup of the spool contents before following the procedure.

Basically you need to increase the value of the parameter NUMFQES. 
So, the procedure is:

1) Update the ESFPARM to increase the value of the parameter NUMFQES.

  • There is a formula to estimate the size of the checkpoint dataset based on the value of some parameters and number of spool datasets basically. See the link below for details:

    OM Spool - Storage Estimates

  • The allocation of the checkpoint file is performed with a simple IEFBR14. A sample JCL can be found in the CBQ4JCL library member BQ4JALOC.
  • The new file is formatted when you start OM Spool with the COLD option.


2) Perform a full backup of the spool contents. See the link below for a procedure to be followed:

Quiesce Spool input/output file activity for a full backup

3) Stop OM Spool

4) Start OM Spool with the COLD option

5) Restore the files using the sample provided in the link above.
