Limitations

The following limitations apply when using the IBM for DB2 iSeries endpoint as a source in a Replicate task:

  • Multi-member (Partitioned) tables are not supported

  • Field level encryption is not supported
  • Journal receivers must be System Managed rather than User Managed.

  • Journals containing minimized data are not supported.

    The MINENTDTA parameter should be set to: MINENTDTA(*NONE)

  • All tables must be in the same journal
  • The DROP TABLE DDL is not supported
  • The RENAME TABLE DDL is not supported
  • The XML data type is not supported
  • The DBCLOB data type is not supported
  • Row size cannot exceed 32740 bytes
  • When the Use table and schema system names option is enabled (in the Advanced tab), only table/schema names that contain uppercase letters, digits, and underscores (_) are supported.

    For more information on this option, see Replicating System Names.

  • Usually, Replicate only applies source database changes to the target if the transactions with the changes were committed before the Full LoadClosedCreates all defined files or tables at the target endpoint, automatically defines the metadata that is required at the target, and populates the tables with data from the source. started. However, due to a known issue with the DB2 iSeries database, records that were deleted from the source as part of an uncommitted transaction will not be replicated to the target during Full Load.

  • DELETE operations in auto-commit mode will be ignored for tables journaled with *AFTER images. In such cases, DELETE operations will only be captured if one of the Add RRN column options is enabled and is set as the only Primary Key.
  • When auto-commit=ON, the timestamp of the last committed transactions will be displayed as "01-01-1970 00:00" in the SOURCE_CURRENT_TIMESTAMP column of the attrep_status Control table.
