Scenario - Define path for alternate index on the employee KSDS file.

Input KSDS File - MATEPK.EMPL.KSDS

Input Alternate Index - MATEPK.EMPL.DEPTAIX

JCL -

----+----1----+----2----+----3----+----4----+----5----+
//MATEPKP JOB (123),'MTH',CLASS=A,MSGCLASS=A,
//             MSGLEVEL=(1,1),NOTIFY=&SYSUID
//********************************************
//* DEFINE PATH
//********************************************
//STEP10   EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN    DD  *
  DEFINE PATH (NAME(MATEPK.EMPL.DEPTAIX.PATH) -
               PATHENTRY(MATEPK.EMPL.DEPTAIX) -
               UPDATE)
/*

Output -

Once the above JCL is submitted, check the MAXCC of the job for any errors. If the MAXCC is 00 or 04, then DEFINE PATH is successful.

The PATH should load with all the keys from the base cluster, and the alternate key should highlight as shown below -

Explaining Example -

In the above example,

• NAME(MATEPK.EMPL.DEPTAIX.PATH) specifies the AIX path.
• PATHENTRY(MATEPK.EMPL.DEPTAIX) specifies alternate index defined earlier.
• UPDATE specifies the alternate indexes should be updated when records are added, modified, or deleted to the base cluster.
