One of the things that need to be done before really starting to install CA Mainframe Software Manager - MVS is the need of a zFS aggregate.

In this document is provided sample JCL to create such an aggregate.


Please change the JCL according you jobcard, datasetname and other JCL requirements and submit to job to create a zFS aggregate.

//  Insert Jobcard 
//* Allocate a zFS aggregate (actually a VSAM linear dataset with 8     
//* KB blocks).                                                         
//* Notes: - There are 6 8 KB per track -> 90 8 KB per cyl.             
//*        - When the total size of a file is greater than 4 GB         
//*          (extended format) the DFSMS DATACLASS must provide         
//*          extended addressability. Add DATACLASS(LSEXT).             
//STEP1   EXEC PGM=IDCAMS                                               
//SYSPRINT  DD SYSOUT=*                                                 
//DISK      DD DISP=OLD,UNIT=3390,VOL=SER=volser                        
//SYSIN     DD *                                                        
  DEFINE CLUSTER (NAME(datasetname) VOL(volser) -                  
                 LINEAR CYL(600 100) SHAREOPTIONS(2))  -                
         DATA (CISZ(4096))                                              
//* Format the zFS as a compatibility mode aggregate. The zFS           
//* aggregate contains 1 zFS file system. The zFS file system has the   
//* same name as the zFS aggregate (and the VSAM LDS).  
//* Specify the datasetname of the CLUSTER NAME defined in the 
//* previous step in the PARM field below.                
//STEP2   EXEC PGM=IOEAGFMT,                                            
//             PARM=('-aggregate datasetname -compat ')            
//STDOUT    DD SYSOUT=*                                                 
//STDERR    DD SYSOUT=*                                                 
//SYSPRINT  DD SYSOUT=*                                                 
//CEEDUMP   DD SYSOUT=*
