PowerExchange IMS Data Map Creation

Step 2. Add a Data Map

Enter a short description of the task here (optional).

Start the PowerExchange Navigator.

On the

Resources

tab, right-click

Data Maps

and select

Add Data Map

The following image shows this right-click menu:

The wizard for creating a data map starts and displays the

Name

dialog box:

Enter the following information:

In the

Schema Name

field, enter a user-defined name of up to 10 characters in length.

You can initially use the name of the data map developer as the schema name. After the data map has been created and tested, you can change the schema name to a schema name that you use for other data maps. Often, the schema name represents the PWXPC application.

In the

Access Method

list, select

DL/1 BATCH

. This setting enables you to use either DL/I or BMP batch access to an IMS database. Both of these access types require that you configure a netport job.

You can select

IMS ODBA

if ODBA is activated for the IMS database. However, subsequent steps in this article assume that you select

DL/1 BATCH

In the Data Map Name
field, enter a user-defined name for the data map of up to 10 characters in length. This name must begin with a letter.

Usually, this name matches the NAME parameter value in the DBD statement in the DBD file. For example, the following DBD statement specifies a NAME value of IMSSAMDB:

DBD   NAME=IMSSAMDB,ACCESS=(HIDAM,VSAM)

Based on this example, you would enter a data map name of IMSSAMDB.

Select

Import Record Definitions

to be able to import a DBD and copybooks into the data map.

Click

The

DL/1 Batch Access Method

dialog box appears:

Enter the following information:

In the

IMS SSID

field, enter an IMS subsystem ID, such as IMS9. Maximum length is four characters.

For DL/1 BATCH access, this value is a logical SSID that matches the SSID that is specified in an IMSID statement in the DBMOVER configuration member and in the registration group. This logical SSID is not used for DL/I access to the IMS database.

In the

DBD Name

field, enter a DBD name.

In the

PCB Number

field, enter the relative PCB number for the DBD in the PSB. If the PSB specifies COMPAT=YES, add 1 to the PCB number.

A PCB number is required for DL/I and BMP access to IMS data. The PSB that is specified in the NETPORT statement in the DBMOVER member on z/OS must contain a PCB entry for the DBD.

You can override the IMS PSB name in the NETPORT statement in one of the following ways:

Explicitly declare it as follows:

PSB=<psb_name>

In the netport JCL, specify the following input substation variable to pass a PSB name override at execution time:

PSB=%PSBNAME

The PSB name override is specified in the PowerCenter

IMS PSBNAME Override

session property for a source or target or in the PowerExchange Navigator

PSB Name

advanced parameter for a database row test. The override value replaces the substitution variable for the session or row test. By using the substitution variable with an override, you can use the same JCL and same set of NETPORT and LISTENER statements for multiple PSBs

In the

Default Codepage

and

Skip First

fields, accept the

Default

values.

Click

Finish

If you selected the

Import Record Definitions

option, the

Import Copybook - Source Details

dialog box appears.
