Concatenation of Operator CLIST

Edit online

Currently, the OPLIST can only be defined in the initialization parameter, MCS.CLIST. This does not allow the user to concatenate their own OPLIST.

The current syntax for the initialization parameter (initparm) is

MCS.CLIST = oplist_dsn

The MCS.CLIST and MCS.SIGNON syntax remains unchanged. However, if the startup JCL contains the DD statement DGAOPLS, IBM® Connect:Direct® builds and saves the dsn list from the JCL instead of using the MCS.CLIST parameter. The JCL statement provides an override of the initialization parameter.

//DGAOPLS DD DSN=oplist_dsn_1
//DD DSN=oplist_dsn_2
//DD DSN=oplist_dsn_n

Note: If the IBM Connect:Direct Server initialization finds the DGAOPLS DD allocated, the MCS.CLIST initialization parameter is ignored. However, the MCS.SIGNON initialization parameter is still required.
