When CICS Vector Table module (DBCVTPR) is re-assembled and re-linked, recycling CICS region is always the quickest and safest way to refresh it. This is the suggested method.
However, there is a way to accomplish this without shutting down CICS.
Here are the steps required to refresh CVT when CICS is active:
- DBOC SHUTDOWN
- rename/save the old DBCVTPR module
- re-assemble and re-link DBCVTPR
- CECI REL,PROG(DBCVTPR) - repeat until you receive INVREQ, as programs can be loaded multiple times
- CEMT I,PROG(DBCVTPR) to then perform Newcopy
- DBOC STARTUP
In case the DBOC STARTUP doesn't autoconnect to the MUF regions, a DBEC CONNECT must be executed.
