2496410 - z/OS: INSUFFICIENT SPACE IN STRUCTURE during the installation of the SAP ENQ Replication into System z Coupling Facility

Symptom

During the installation of the SAP ENQ Replication into System z Coupling Facility as described in the PDF document SAP_ENQ_REP_Inst.pdf that is attached to SAP Note 1753638,
the enqueue server fails during startup.

The z/OS system log shows the following error:

IXC471I UNABLE TO CREATE NOTE PAD SAPSSS.ENQUEUE.NN 955                   
 REQUESTER JOB NAME: jobname  SYSTEM NAME: sysname                           
 REASON: NO SUITABLE HOST STRUCTURE FOUND                                  
 HOST STRUCTURES CONSIDERED:                                               
 STRUCTURE NAME    STATUS/FAILURE REASON              DIAG                 
----------------  ---------------------------------  --------             
IXCNP_SAPSSSxx    INSUFFICIENT SPACE IN STRUCTURE    0000191C             

BPXF024I (SSSADM) SAPENQ00 STARTUP ERROR : Creating XCF note pad 958      
SAPSSS.ENQUEUE.NN by service IXCNOTE failed with return code 0x000C       
and reason code 0x18050CA5.

 

Also in the enqueue server trace file dev_enqrepl file:

>>> REPSTORE CF (repstzOSCF.so): STATISTICS - Note pad as replication table for SAP system SSS and instance number NN has maximum of 56415 entries
>>> REPSTORE CF (repstzOSCF.so): ERROR (function <repstCreateTable(REPST_TABLENAME *, REPST_TABLEINFO *, int *)> line 725): unable to create new XCF note pad in CF. CFNPCRE return code 0x000C - reasonCode 0x18050CA5.
No coupling facility structure suitable to create XCF note pad as replication table for SAP system SSS
Modifying existing (most probably increasing their size) or defining additional structures to the CFRM policy might solve the problem
