Creating runtime Fast Path routing code resource and descriptor definitions with the CREATE command

With dynamic resource definition (DRD) enabled, you can create runtime resources and resource descriptors dynamically, eliminating the need to use the online change process or the batch system definition process with an IMS cold start.

Create runtime Fast Path routing code resources and descriptor definitions using the CREATE RTC and CREATE RTCDESC commands.

Procedure

  1. Optional: Issue a QUERY RTCDESC DEFAULT(Y) SHOW (ALL) command to view the current Fast Path routing code default settings and evaluate whether they meet your requirements for the new Fast Path routing code resource or descriptor definition.
    If the default settings do not meet your requirements, you have the following options:
    • Override the default settings by issuing the CREATE command with parameter values that meet your requirements.
    • Create the resource or descriptor definition based on an existing resource or descriptor definition by using either the LIKE (RSC(resource_name)) keyword or the LIKE (DESC(descriptor_name)) keyword
    • Create a default descriptor by issuing a CREATE RTCDESC NAME() SET (DEFAULT(Y)) command with the settings that meet your requirements.
  2. Issue a CREATE RTC to create Fast Path routing code resources or a CREATE RTCDESC command to create Fast Path routing code descriptor definitions.

For the details about parameters for the CREATE command, see IMS Version 15.5 Commands, Volume 1: IMS Commands A-M.

If you are using the IMSRSC repository or a set of system resource definition data sets (RDDSs) to store your Fast Path routing code resource and descriptor definitions, the routing codes associated with both Fast Path potential FP(P) and FP(E) transactions are maintained in the repository or RDDS.

If it was not specified in the EXPORT DEFN command or in the RDDS to Repository utility (CSLURP10), the routing code for the FP(E) transaction is automatically created in the repository by RM.
