ims_ssid

The IMS subsystem ID (SSID).

If you import source DBD information from the IMS catalog, this

ims_ssid

value is required and must match the

ims_ssid

value in an IMSBSDS statement.

For IMS log-based CDC, this

ims_ssid

value must match the

Recon Identifier

value specified in the registration group.

If you create data maps that use the

IMS ODBA

access method, this value is required for PowerExchange to connect to the IMS subsystem to access data.

dbdlib

or DD:

XXXXXXXX

Provides PowerExchange access to the IMS DBD which is required for activities such as reading IMS unload files, registering IMS sources for CDC, and running utilities, including DTLURDMO and DTLUCBRG. In this parameter, you can either specify the IMS DBD library dataset name in line or specify a DD name for PowerExchange to search. By specifying DD:

XXXXXXXX

, where

XXXXXXXX

is the DD name coded in the JCL for the component requiring access, you can have one or more DBD libraries for a system allocated to the specified DD name.

If you use the DD:

XXXXXXXX

, PowerExchange uses the first DBDLIB it finds in the concatenated list and continues processing. Ensure that you place this DD with the one or more DBD libraries in the appropriate JCL or started task.

RECON=(

recon1

,[

recon2

],[

recon3

])

Optional. The RECON data sets for IMS log-based CDC. If you include the RECON parameter, you must specify at least one data set name. You can enter each data set name on a separate line in the DBMOVER member.

You can specify up to 10 IMSID statements in a DBMOVER member.
PowerExchange does not require the IMSID statement to create data maps if you import DBD information for source objects from the DBDLIB library. However, when you perform IMS bulk data movement operations, PowerExchange matches the
ims_ssid
in the IMSID statement against the
IMS SSID
value in the data map to determine the DBDLIB data set to use. Also, for IMS log-based CDC, PowerExchange matches the
ims_ssid
value in the IMSID statement against the
ims_ssid
value in the
Recon Identifier
field in the registration group.
If you create data maps by importing DBD information for source objects from IMS catalog, the
ims_ssid
in the IMSID statement is required to find a matching IMSBSDS statement. If you create a registration group for IMS log-based CDC, the
ims_ssid
value in the
Recon Identifier
field matches against the
ims_ssid
value in an IMSBSDS statement.
