Step 5: Creating the working datasets

After you have customized the variables for your site, you must then create the working datasets for your topology.

1. In the ++HBRHLQ++.SHBRJCL(HBRUUPTI) data set member, customize the value of ++HBRHLQ++ which represents the product installation high level qualifier.
2. Ensure that ++HBRHLQ++.SHBRPARM(HBRINST) has been configured correctly for your environment and required topologies.
3. Ensure that ++HBRHLQ++.SHBRPARM(HBRCTRL) has been configured correctly for your environment and required topologies:
   For example:

   CREATE ZRES HBRMODE=CONSOLE HBRSSID=HBR1 HBRWORKDS=RULES.WORK.HBR1

   creates a single Rule Execution Server console

   CREATE ZRES HBRMODE=RULE HBRSSID=HBR2 HBRWORKDS=RULES.WORK.HBR2

   creates a single zRule Execution Server for z/OS instance.

   The HBRMODE variables:

   • CONSOLE: The server starts the Rule Execution Server console for managing the other servers in the group. The server does not accept connections from local clients.
   • RULE: The server accepts and processes rule executions from local clients. This mode is used when you run and manage rules from a mainframe.
   • ADS: The server serves as an endpoint that handles Decision Intelligence Client Managed Software decision requests from COBOL programs.
   • HTDS: The server starts the Hosted Transparent Decision Service (HTDS) to enable rule execution via REST or Web Services.
   • TEST: The server is being used for testing and does not accept connections from local clients. This mode is used to start SSP and run rules only from the console.
   • NATIVE: The server does not start a JVM to do any work. Instead, it is a lightweight address space to provide authorized services to embedded zRule Execution Server for z/OS® instances.
4. Submit ++HBRHLQ++.SHBRJCL(HBRUUPTI).
5. If an error occurs, check the HBRUUPTI job output.
   In particular check the following points:

   • All mandatory variables are set.
   • Variable pairs do not have identical values where this is not permitted.
   • Variables that must be set to integer values are set correctly.
   • Variables that are case-sensitive are set using uppercase, lowercase or mixed case as required.
