Replication Guide and Reference

Operating the Apply program

This section describes what you need to know before you start the Apply program and how to use the Apply program for forward recovery. For information about operating the Apply program (for example, starting, stopping, or scheduling) in a specific operating system environment, see Operations.

Before you start the Apply program, ensure that:

• The control tables are defined.

• For Windows and UNIX: A password file has been created, if necessary, for end-user authentication at the source server. See Providing end-user authentication at the source server for more information.

• At least one subscription is created and activated.

• The Apply program package is created.

  See the Apply for OS/390 program directory for information on BIND programs to create the Apply program packages. You must bind the Apply program to both the source and target databases.

  See Configuring Apply for Windows and OS/2 for information on bind programs to create the Apply packages for Windows and OS/2.

  See Configuring the Apply program for UNIX platforms for information on bind programs to create Apply packages for UNIX platforms.

  See Creating DPROPR/400 packages to use with remote systems for information about the CRTDPRPKG command, which creates the packages that are necessary for DataPropagator Relational for AS/400 to work with remote systems.

• The Capture program is started, and the ASN0100I initialization message was issued (if you are running a Capture program).

• You have proper authorization.

• For OS/390:

  • Ensure that all STEPLIB libraries of the Capture for MVS RUN JCL (if you are running Apply for OS/390) are APF-authorized.

  • Customize and execute the following JCL:

    • The link-edit sample JCL

    • The sample JCL to build the VSAM message file

    • The Apply bind sample JCL

    • The Apply Run/Invocation sample JCL

  • You must have SYSADM or DBADM privileges at the source, control, and target server. You must also have the proper authorization to run the Apply program, including EXECUTE privileges for Apply program packages.

  • You must have DBADM or CONTROL or SELECT authority that meets all requirements for defining a replication source and target.

• For AS/400: For Version 5, the Capture program is started on the source server before you start Apply for the first time. The Capture program updates the SYNCHTIME and SYNCHPOINT columns in the ASN/IBMSNAP_REGISTER table before the Apply program is started. The Apply program assumes that if a GLOBAL record is present in the ASN/IBMSNAP_REGISTER table, the SYNCHTIME and SYNCHPOINT columns are not null. For Version 1, the Apply program can be started before the Capture program.
