IMSBSDS Statement

The IMSBDDS statement identifies the high-level qualifier of the IMS bootstrap data set, which is required to retrieve DBD information in DBGEN format from the IMS catalog. This statement also indicates the order of locations, such as the IMS catalog and IMS DBDLIB library, to search for DBD information.

This statement is required for PowerExchange to use the IMS catalog API to retrieve DBD information in DBGEN format from the IMS catalog when the IMS control region is not running or when you use an IMS version earlier than IMS 15. PowerExchange uses DBD information in DBGEN format when you create capture registrations in the PowerExchange Navigator or perform IMS unload processing. This statement is also required for PowerExchange to use the IMS Catalog Library Builder Utility, DFS3LU00, to get DBD information in source format from the IMS catalog when you create data maps from the PowerExchange Navigator.

Use of the IMS catalog is optional. By default, PowerExchange gets DBD information from the DBDLIB library.

Enter this statement in the DBMOVER configuration file on the PowerExchange Listener system.

Required to get DBD information from the IMS catalog

IMSBSDS=(ims_ssid
      ,bootstrap_hlq
     [,search_preference]
)

ims_ssid: Required. The IMS subsystem ID (SSID) for the subsystem that contains the source objects. This value must match the IMS SSID value that is specified in the first positional parameter in an IMSID statement.
bootstrap_hlq: Required. The high-level qualifier of the IMS bootstrap data set that is in the IMS directory associated with the IMS catalog for the IMS SSID.
search_preference: Optional. The order in which PowerExchange searches locations for DBD metadata for source objects. Valid values are:

D
. First search the DBDLIB library and then search the IMS catalog, if available.
C
. First search the IMS catalog and then search the DBDLIB library.
O
. Search the IMS catalog only.

If you do not specify an option, PowerExchange searches only the DBDLIB library by default and does not use the IMS catalog.
