Registration Tag Names

A registration tag name is a unique identifier that PowerExchange generates and assigns to a data source registered for CDC.

PowerExchange uses these registration tags to identify the change records of interest for CDC processing. The PowerExchange Logger for z/OS, PowerExchange Condense, and PowerExchange Logger for Linux, UNIX, and Windows store a registration tag name with each change record in their log or condense files.

For z/OS data sources that are processed by the z/OS ECCRs and PowerExchange Logger for z/OS, the registration tag name is also referred to as the EDMNAME.

When you create a capture registration, PowerExchange assigns the same registration tag name to the capture registration and the corresponding extraction map that PowerExchange generates. If you manually add another extraction map for the capture registration, this additional extraction map has the same registration tag name.

The registration tag name format varies depending on the source type. The following list describes the format of the registration tag name for each source type:

In this list, the different types of values that compose the registration tag name are separated by underscores for legibility. The underscores do not appear in the tag names.

VSAM: The registration tag name that is assigned to a VSAM data set depends on the length of the VSAM data set name in the data map.

If the VSAM data set name is less than or equal to 28 characters, the registration tag name has the following format:

VSAMdatasetName

For example, the data set name of USERID1.VSAM.EDMSRCV.MAKEITA is 28 characters in length. For this data set, PowerExchange generates the following registration tag name:

VSAMUSERID1.VSAM.EDMSRCV.MAKEITA

If the VSAM data set name is equal to or greater than 29 characters, PowerExchange truncates the data set name to 23 characters and appends an ascending numeric value, nnnnn, to create the registration tag name. The registration tag name has the following format :

VSAMdataset_namennnnn

For example, the data set name of USERID1.VSAM.EDMSRCV.MAKEITAB is 29 characters in length. For this data set, PowerExchange generates the following registration tag name:

VSAMUSERID1.VSAM.EDMSRCV.MA00001

if you have subsequent data set names that are longer than 28 characters and have the same first 23 characters as a previous data set name that is longer than 28 characters, the PowerExchange Navigator increments the appended numeric value nnnnn by 1:

VSAMUSERID1.VSAM.EDMSRCV.MAnnnnn+1

For example, if the data set name is USERID1.VSAM.EDMSRCV.MAKEITAV, PowerExchange generates the following registration tag name:

VSAMUSERID1.VSAM.EDMSRCV.MA00002
