Invoking Backward Recovery from JCL

Describes how to invoke Backward Recovery from JCL.

To recover a database using JCL, you can invoke Backward Recovery.

To invoke Backward Recovery from JCL, include the following as part of a data SYSIN card:

TLOG=$ES_IMS_TLOG_PATH\tlogName.TLOG

where tlogName is the name of the TLOG file to be used in the recovery. For example:

//DBUJCL01 JOB 'IMS DATABASE UTILITY',CLASS=A,MSGCLASS=A
//*--------------------------------------------------------------------
//* Copyright (C) 1991-2010 Micro Focus (IP) Limited.
//* All rights reserved.
//*-------------------------------------------------------------------
//*
//* This job demonstrates using JCL to invoke Backward Recovery.  
//*
//STEP01  EXEC PGM=MFDBUJCL,PARM='ROLLBACK'
//SYSOUT  DD SYSOUT=*
//SYSIN   DD *
TLOG=$ES_IMS_TLOG_PATH\DMOAPPL-13070111330849.TLOG       
/*     
//

Note: As an alternative, you can recover a database from JCL using the Rebuild utility. See Rebuild Utility for details.
