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: 

  2. rename/save the old DBCVTPR module
  3. re-assemble and re-link DBCVTPR 
  4. CECI REL,PROG(DBCVTPR) - repeat until you receive INVREQ, as programs can be loaded multiple times 
  5. CEMT I,PROG(DBCVTPR) to then perform Newcopy 

In case the DBOC STARTUP doesn't autoconnect to the MUF regions, a DBEC CONNECT must be executed.
