SHPBK Prolog
Name : HCPSHPBK DSECT : SHPBK Description: Map or Generate sys def table for CSE Notes : Invocation - HCPSHPBK LNAME=system-name, TYPE=M|S TQ1=tq1, IND=ind, CVMID=cvmid, ALIAS=alias, GENCODE=YES|NO where: "system-name" is the cross system node name of an associated system. TYPE=M means that the system being described is the main system, that is, the system on which this copy of the VM/XA SP control program with CSE active will run. TYPE=S means that the system being described is a secondary system, one associated with the main system in the complex. "tq1" is the number of seconds that associated system "system-name" will wait for a response before assuming that the system it was communicating with is down. The default timeout value is 12 seconds. "ind" is a numeric value from 1 to 8, the index of this entry in the associated system tables. "cvmid" is the user-id of the CSE Communication Virtual Machine (CVM). "alias" is another name for "system-name". GENCODE=YES will cause the actual table to be built. Otherwise a DSECT is generated, since GENCODE=NO is the default.
