Execute the COMM function with the following command format:
►►─ COMM OPTION=STATUS ─┬──────────────────────────┬──────────────────────────► └─ ,DEST= ─┬─ PRINTER ◄ ─┬─┘ └─ CONSOLE ───┘ ►─┬──────────────────────┬───────────────────────────────────────────────────►◄ └─ ,IGN68= ─┬─ NO ◄ ─┬─┘ └─ YES ──┘
Command
Invokes the function to pass communication to the MUF.
Required Keyword
Requests that the current status of tasks in MUF be displayed.
Note: In z/OS, when DBUTLTY is executing on the same System as the MUF, the data is returned directly from memory with no MUF request. Also note that the DBUTLTY COMM OPTION=STATUS provides more information than the console STATUS, and this additional information may or may not be important to see.
Optional Keywords
Specifies the destination for the status report. CONSOLE causes the report to appear on both the console and SYSPRINT. PRINTER causes the report to appear on SYSPRINT only.
Note: When routing print to the console, headings do not appear.
CONSOLE (may be abbreviated as CON) or PRINTER (may be abbreviated as PRI)
PRINTER
Specify IGN68=YES to ignore a return code 68. IGN68= is allowed for every ACCESS and COMM function. By ignoring return code 68, you can set up and run JCL that incorporates a stack of DBUTLTY functions without requiring that the MUF be enabled. IGN68= would therefore be useful, for example, if you wanted to load a database without first enabling the MUF, perhaps to allow restart to properly occur. Following is an example showing a stack of DBUTLTY functions that use IGN68=.
ACCESS STATUS=UTLTY,DBID=997,USERS=WAIT,IGN68=YES COMM OPTION=CLOSE,DBID=997,IGN68=YES INIT AREA=IXX,DBID=997 INIT AREA=A01,DBID=997 LOAD AREA=A01,DBID=997,FORMAT=NONE,KBYTES=9999,SORT=1 ACCESS STATUS=WRITE,DBID=997,IGN68=YES
Note: If the CXX is externally secured, the INIT and LOAD functions do not execute without the MUF being available, and IGN68=YES is therefore not recommended.
A function or functions specified with IGN68=YES generates message DB13001E to note that the function did not occur. Because no error was recognized, however, other functions in the stack continue to execute, and the DBUTLTY step ends without a recognizable error. Message DB13001E signals that the MUF was not enabled.
Note: For details about DB13001E, see the CA Datacom/DB Message Reference Guide.
The DBSYSID macro parameter DELAY68= can be used to specify the number of minutes that the MUF connection can wait if the MUF is not currently available. But if IGN68=YES is specified, DELAY68= is ignored and the function continues. If the delay is desired, however, either do not specify IGN68=, in which case it defaults to NO, or specify IGN68=NO.
NO or YES
NO
