Viewing or Editing IMS Options for a Table

The options defined on the

IMS Options

tab in the

Table Properties

dialog box indicate how data is written to an IMS database, and provide default values for optimal performance when working with IMS.

These options are set to default values that cause PowerExchange to:

Treat IMS as a relational target

Behave like an IMS COBOL application program

Editing the default values for these options impacts the amount of data sent to the database and the time required to write the data.

To view or change IMS options:

Open an IMS data map.

On the

Data Map

tab in the

Resource Explorer

, right-click a table and select

Properties

On the

IMS Options

tab in the

Table Properties

dialog box, define IMS options for the table.

Do not edit the default value for the

Delete Options

option unless you are familiar with the IMS hierarchy. Changing these settings can result in loss of IMS data.
