//****************************************************************
//*
//*  $SEG(CBRISQLX) COMP(OSR) PROD(OAM):
//*
//*  OAM DB2 Database Definition Job (for Administration
//*  Databases).
//*
//*  This job will create the OAM Administration databases,
//*  tables, and indexes in DB2.
//*
//*  Before running this job, you must change the following:
//*
//*  1. Change "cat_name" to the DB2 VCAT name used
//*     for defining the VSAM data sets in CBRIALCX.
//*
//*  2. Change "auth_id" to the identifier(s)
//*     authorized for the respective group.
//*
//*  3. Change the name in the DSN SYSTEM(DB2) statement to
//*     the name of the DB2 Subsystem in your installation.
//*
//*  4. Change the data set name in the RUN statement
//*     LIB('DB2.RUNLIB.LOAD') phrase to the data set name used
//*     in your installation for the DB2 RUNLIB.LOAD data set.
//*
//*  5. Change the PLAN name (DSNTIA51) in the RUN statement to
//*     match your current DB2 version and release level.
//*
//*
//*  CHANGE ACTIVITY:
//*    $L0=JDP3227 320 890601 TUCJRL: Initial Release
//*    $L1=HDZ11D0 140 970331 TUCSPP: Specify TYPE 1 INDEX for
//*                                   DB2 4.1 or above level
//*    $L2=HDZ11G0 R13 001016 TUCLJT: Removed reference to type 1
//*                                   indexes, no longer supported
//*                                   by DB2 and removed SUBPAGES
