There may be times when users of SYSVIEW will receive the following message which prevents them from accessing Sysview:
GSVX086E*Allocate dsname failed, error 043C0000
To prevent/eliminate this from occurring, ensure that a value is coded for the DYNAMNBR= parameter in the EXEC PGM=GSVXMAIN in the SYSVUSER proc.
From IBM's JCL Reference manual: "If no DYNAMNBR parameter is specified, the default is 0."
The SYSVUSER proc in SAMPJCL is shipped with a value of 1000, i.e.
//SYSVIEW EXEC PGM=GSVXMAIN,REGION=0M,TIME=1440, // DYNAMNBR=1000,PARM='&MEM'
