Issue/Introduction

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: 

  1. DBOC SHUTDOWN
  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 
  6. DBOC STARTUP 

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