Issue/Introduction

Trying to increase the ENF IXX700 database size using the procedure documented at: 

Manage ENF Database Full Conditions

Steps executed: 
Stop the Broadcom products that are currently using ENF for recording events.
Stop ENF. If the site is running with an external MUF, shut down the MUF.

Then run the CAW0JCL CADB007 DBUTLTY job to backup the ENF database but that end with ABEND U0004 with messages: 
DB13001E - UNEXPECTED RETURN CODE 68 (1) MULTI-USER IS NOT UP (OR EOJ IN PROCESS)   
DB10045E - ABNORMAL TERMINATION DUE TO ERROR(S)                                     

Since the JCL seems to suggest that the MUF needs to be up, trying above job with ENF running but the job also fails with ABEND U0004 this time with messages:
DB13001E - UNEXPECTED RETURN CODE 51 (1) INVALID MIX OF DATACOM/DB UTILITIES            
DB10045E - ABNORMAL TERMINATION DUE TO ERROR(S)

About the CADB007 job: 

It seems that it is a case of the Database being up and in used by ENF when running these jobs.

The MUF needs to be up but it must be running independent from ENF.  

The  r14.1 PTF RO54507 description explains how to bring the MUF up but it could not be in use by ENF.

So ENF must be stopped, start Datacom DBxxxSTRT and run the jobs with the MUF not in use by ENF.

Looking at  r14.1 PTF RO54507, the hold actions state that the MUF needs to be active but not in use with ENF. 

 

About the CADB008 job: 

There is a problem in the JCL: 

//ENF700  DD DSN=SYSS.ENF.AD.IXX0700,   -- should be ...   //IXX700
