Activating IMS Index Builder

After you complete the SMP/E installation, activate IMS™ Index Builder.

About this task

To activate IMS Index Builder, you must configure the environment so that IMS Index Builder can perform the following actions:

Start some subordinate address spaces for scans and sorts.
Allocate stripe data sets to pass data between its address spaces; the data includes the WTO messages, the sort messages, the index records, and the duplicate keys. IMS Index Builder allocates one or more stripe data sets in each address space.

Configure the environment so that IMS Index Builder can start some subordinate address spaces.
1. Ensure that the target load library SIIULMOD is APF authorized.
  For more information, see Enabling inter-region communication (APF authorization).
2. Copy the procedure, IIUBSRT, from the target library, SIIUPROC, to your started task procedure library.
3. Optional: Specify the job names for the subordinate address spaces.
  For more information, see Defining the subordinate address space procedure.
4. Define RACF® authorization to establish security authorization for subordinate address spaces.
  For more information, see RACF considerations.
Configure the environment so that IMS Index Builder can allocate stripe data sets.
1. Optional: Specify the high-level qualifier of stripe data sets. The default is IIU.STRIPE.
  For more information, see the explanation of the IIURDFLT CLASS entry in Defining runtime parameters.
2. Optional: Set up the SMS environment to associate the high-level qualifier of stripe data sets with the SMS-managed volumes.
3. Define RACF authorization to establish proper access to stripe data sets.
  For more information, see RACF considerations.
Configure the environment so that IMS Index Builder can issue DBRC commands and send DBRC API requests.
For more information, see Configuring for DBRC command authorization.
