SVC2= parameter for procedures

Specifies the Type 2 SVC number that IMS uses.

You can specify a value in the range 200 - 255 for this parameter in one of the following locations. If you do not specify this parameter, IMS uses a default value of 254.
Important: If you use the Open Database Access (ODBA) interface or the database resource adapter (DRA) and you do not want to use the default value of 254 for the type 2 SVC number, you can define the number only by using the DFSIDEF macro of the DFSIDEF0 module.
  • In the DFSPBxxx member of the IMS PROCLIB data set
  • In JCL
  • On the DFSIDEF macro of the DFSIDEF0 module. If you specify the type 2 SVC number on the DFSIDEF macro, assemble and bind the DFSIDEF0 module into the IMS execution library.
The value that is specified in the DFSPBxxx member or in JCL overrides the value that is specified on the DFSIDEF macro.
