IBM DB2 for z/OS as Replicate Data Server

Learn about the primary database issues and considerations specific to the DB2 UDB for z/OS data server in an SAP replication system.

For information about basic replication system administration, see the Replication Server Administration Guide Volume 1.

• DB2 UDB for z/OS Replicate Data Server Environment
  As a replicate data server in a gateway environment, DB2 UDB for z/OS interacts with the Mainframe Connect DirectConnect for z/OS Option database gateway, which accepts commands from the replicate Replication Server and applies those commands to a replicate DB2 UDB database.
• DB2 UDB for z/OS System Management
  With the introduction of heterogeneous datatype support (HDS) in Replication Server version 12.0, the create connection command’s dsi_sql_data_style parameter is now invalid.
• Replication Intrusions and Impacts in DB2 UDB for z/OS
  The only significant intrusions or impacts to the replicate DB2 UDB are the database objects created by the connection profile that creates three tables in the replicate database to support Replication Server operations.
• DB2 for z/OS Replicate Database Permissions
  Replication Server requires maintenance user ID that you specify in the Replication Server create connection command to apply transactions in a replicate database.
• Replicate Database Connectivity for DB2 UDB for z/OS
  A Replication Server database connection name is made up of two parts: a data server name (server_name) and a database name (db_name).
• Replicate Database Limitations in DB2 for z/OS
  Replication of large object (LOB) datatypes (BLOB and CLOB) is supported directly by MainframeConnect DirectConnect for z/OS Option.
• DB2 for z/OS Replicate Database Configuration
  The heterogeneous datatype support (HDS) feature of Replication Server provides configuration information that allows you to set up the HDS feature in the replicate Replication Server and the DB2 UDB for z/OS replicate database.
