Issue/Introduction

Datacom Server is running out of memory/storage, getting S878-10 abends:

IEA705I ERROR DURING GETMAIN SYS CODE = 878-10

Resolution

Perform the following:

1. Apply all the latest PTFs to the Server mainframe component.
   
   
2. In the JCL EXEC statement specify REGION=0M or if more than 32M above the line is needed, specify a large value like REGION=64M.
   
   
3. Ensure the Datacom Server startup JCL has a CEEOPTS DD statement with the recommended LE runtime options. These include a HEAPPOOLS statement to control the allocation of storage.
   
   
   • For Datacom/DB:

     //CEEOPTS  DD DSN=hlq.CAYTMAC(CEEUOPT),DISP=SHR

   • For Datacom/AD:

     //CEEOPTS  DD DSN=hlq.CAAXMAC(CEEUOPT),DISP=SHR

4. If this is a Datacom/AD Server that's being used by the CA 7 REST API then change the HEAPPOOLS setting in the CEEUOPT member to the following: 

   HEAPP(ALIGN,                                          
         384,79,624,15,1880,90,4176,90,5752,54,9560,90,  
         11016,35,13904,86,20048,90,30816,90,32760,90,   
         64000,90)
   
   

5. If the problem is still not resolved, then tune the LE heap storage allocations as explained in the IBM documentation section Tuning Heap Storage.
   The optimal HEAPPOOLS settings are dependent on the traffic in Datacom Server and the queries being sent to/from MUF. This can only be tuned at the customer site.
