When SCC Monitor gets control, the product will search the DD statements associated with the job step or TSO session. Several functions within the product are controlled by the existence of special DD statements.
The DEFPROD statement in the rules language defines the default reserved DD names. These reserved DD statements can be used to bypass Monitor control, or enable debug- ging facilities. The default reserved DD names follow:
MONIGN All SCC Monitor processing will be bypassed for any job step or TSO session that contains MONIGN. To disable the ability to bypass Moni- tor processing, place an invalid DD name on the DDNAME IGNORE(...) subparameter on the DEFPROD statement. Note: this DD is primarily used by SCC Monitor/Realtime.
MONLOG This DD statement can be used by the product to write logging mes- sages produced by DIF common service routines. The MONLOG DD statement is used for SCC Monitor problem determination, and should only be used when requested by technical support. The DDNAME LOG(...) subparameter on the DEFPROD statement can be used to mod- ify this reserved DD name.
MONMSG This DD statement can be used by SCC Monitor to disable message level processing used by internal and rules messages. The MONMSG DD statement is usually used for problem determination, and should only be used when requested by technical support. The DDNAME MSG(...) subparameter on the DEFPROD statement can be used to modify this reserved DD name.
MONTRACE This DD statement can be used to enable the rule tracing facility. When this DD statement is encountered in a job step or TSO session, messages will be written about the compare operations that occur during rules pro- cessing. The DDNAME TRACE(...) subparameter on the DEFPROD statement can be used to modify this reserved DD name.
