Installing the type 2 SVC module

The IMS Type 2 SVC must be incorporated into the z/OS® nucleus.

Attention: The SYS1.NUCLEUS must not have secondary extents. z/OS cannot recognize secondary extents.

To incorporate the IMS Type 2 SVC into the z/OS nucleus, perform one of the following tasks:

Bind the Type 2 SVC with the z/OS nucleus.
You can bind the Type 2 SVC with the z/OS nucleus using one of the two following steps.
1. Invoking the Binder utility through a batch job
2. Creating and then performing a RECEIVE and APPLY for an SMP/E USERMOD
Load the Type 2 SVC from SYS1.NUCLEUS using the Nucleus Module Loader facilities.
1. Create a Nucleus Module List (NML) that contains the list of IMS SVCs that you want loaded into the z/OS nucleus. IMS uses the IEANS001 NML.
2. Assemble and bind the Type 2 SVC into SYS1.NUCLEUS.
This method is included as an example in the IVP materials.
Load the Type 2 SVC from SYS1.NUCLEUS using a SYS1.IPLPARM member, NUCLSTxx.
1. Bind the IMS SVCs from IMS.SDFSRESL into SYS1.NUCLEUS.
  Attention: Determine, from the z/OS systems programmer, the appropriate NUCLSTxx member to use. Note that the LOADxx member and its associated NUCLSTxx member must both reside in SYS1.IPLPARM. If the 2 members are not in this library, IMS will enter a Disabled Wait state and the IPL process stops.
2. Define an INCLUDE statement for the IMS SVC in the NUCLSTxx member of SYS1.IPLPARM.
Load the Type 2 SVC from SYS1.NUCLEUS using a SYS1.PARMLIB member, NUCLSTxx.
1. Bind the IMS SVCs from IMS.SDFSRESL into SYS1.NUCLEUS.
  Attention: Determine, from the z/OS systems programmer, the appropriate NUCLSTxx member to use. Note that the LOADxx member and its associated NUCLSTxx member must both reside in SYS1.PARMLIB. If the 2 members are not in this library, IMS will enter a Disabled Wait state and the IPL process stops.
2. Define an INCLUDE statement for the IMS SVC in the NUCLSTxx member of SYS1.PARMLIB.
