Step 1: Authorizing the load library

After you install the Decision Server for z/OS® data sets, you must make the ++HBRHLQ++.SHBRAUTH load library APF-authorized.

About this task

Important: If Decision Server Events is the only Decision Server for z/OS execution environment you plan to use is, omit this step.

If the load library is not already authorized, add the Decision Server for z/OS load library to the list of authorized libraries.

If you execute your rules in a CICS® or IMS environment by using WebSphere® Optimized Local Adapters (WOLA), the WOLA load libraries must also be APF-authorized. For more information, see Configuring CICS to run rules through WOLA and Configuring IMS to execute rules through WOLA.

Add the ++HBRHLQ++.SHBRAUTH load library to the list of APF-authorized libraries by using the following command:
```
SETPROG APF,ADD,DSNAME=++HBRHLQ++.SHBRAUTH,SMS
```
where ++HBRHLQ++ represents the high-level qualifier that is assigned to Decision Server data sets during installation.

Consider adding a definition to the system parameter library (parmlib) member PROGxx to make it permanent. For example:
```
APF ADD DSNAME(++HBRHLQ++.SHBRAUTH) SMS
```
Provide RACF® authorization for the ++HBRHLQ++.SHBRAUTH load library by using the following commands:
```
RALTER PROGRAM * ADDMEM('++HBRHLQ++.SHBRAUTH'//NOPADCHK)
```
