Create, or modify as needed, entries in the SRTT and then reassemble and relink the module RHDCSRTT for the security domain. An example of the external class and external name construction rules to secure OCF is:

#SECRTT TYPE=ENTRY,RESTYPE=TASK,SECBY=OFF,                                    X
  EXTNAME=(RESTYPE,RESNAME),EXTCLS='CA@IDMS'
#SECRTT TYPE=OCCUR,RESTYPE=TASK,RESNAME='OCF', SECBY=EXT
Consult with the security department to ensure that the ESM contains the correct rules to secure the entries and permit access to the appropriate users.

After making the above changes, assemble and link RHDCSRTT to create a new SRTT. To implement the new SRTT, either recycle any CVs that use the SRTT or issue these commands:
 
   DCMT VARY NUCLEUS MODULE RHDCSRTT NEW COPY 
   DCMT VARY NUCLEUS RELOAD
