The batch VSAM ECCR does not capture change data for the following items:

Environments with multiple task control blocks (TCBs)
Natively updated alternate indexes
Records that are larger than 32,660 bytes
Spanned ESDSs
Paths defined over ESDSs
Control interval (CI) mode updates
VSAM data sets that are opened with record-level sharing (RLS) protocols
Applications that use request parameter lists (RPLs) that are coded with OPTCD=ASY for asynchronous processing for VSAM files
If you use these applications, unpredictable results can occur.

The batch VSAM ECCR uses an internal exclude table to exclude VSAM data sets that have certain names or prefixes from change data capture. The exclude table contains the following types of entries:

Complete load module names
Prefixes for load module names
Prefixes for data set names

Data sets that begin with any data set prefix in the internal exclude table.

Data sets that are opened by load modules that match the specific load module names or prefixes in the internal exclude table.

The following table lists the load module names and prefixes in the internal exclude table:
