Editing an Index for a Source Table

Editing an Index for a Source Table

You can optionally edit indexes that are defined for a mapped source table.
  1. On the
    Map Tables
     tab, select a mapped source table. Then click the
    Show Indexes
     icon button above the source tables filter field, or right-click a mapped source table and click
    Show Indexes
    .
    The
    Indexes
     dialog box appears.
    The Indexes dialog box lists all indexes that are defined for the source table.
    The upper list box lists all of the indexes that are defined for the source table. If you select an index row in the upper list box, the index column or columns appear in the lower list box. By default, index columns are displayed in the order in which they are defined in the source table.
    You can click the
    Index Columns
     heading to sort the list of index columns in alphabetical order. Click the column heading a second time to sort the list in reverse alphabetical order.
  2. In the upper list box, edit the parameters in an index row, as needed.
    The following table describes the index parameters:
    Parameter
    Description
    Unique
    Select this option if the index is unique.
    Primary key
    Select this option to use the index as a primary key. You can specify only one primary key for a table. If you select more than one primary key, the Informatica Data Replication Console displays an error and ignores the current primary key.
    Supplemental logging
    Select this option to enable supplemental logging for the index columns. Data Replication enables supplemental logging for all index columns by default.
    If you use SQL Apply mode, supplemental logging for columns that are mapped to target index columns help preserve the proper order of updates for multi-threaded apply processing.
    User defined
    Select this option to enable user-defined mode. In user-defined mode, you can set the
    Unique
    ,
    Primary key
    , and
    Supplemental logging
     parameters to values that are different from those that are defined for the index in the source database. You might need to change these parameters to correctly replicate changes to the target.
    User-defined parameters have priority over the index definitions in the source database and do not affect those definitions. If you revert a user-defined index, all of the index parameters revert to the index definitions in the source database.
    You cannot edit the
    Not Null
     check box in the lower list box. This check box indicates whether or not the column can contain nulls.
  3. Click
    OK
    .
