Displaying the VSAM Data Sets from Which Changes Are Captured

Use the EDMC transaction with the DISPLAY or DISP keyword to display the VSAM data sets from which changes are being captured.

From a CICS terminal, enter the transaction:

EDMC DISP

The following sample output indicates that no VSAM files are participating in change data capture:

EDMC DISP           PWXEDM CICS/VSAM Change Capture         Init Date: 09/15/16

 No files are currently participating in CICS/VSAM Change Capture

The following sample output indicates that six VSAM data sets that are participating in change capture, but three data sets are not participating because the

DSN=dataset_name
,NOCAPTURE

override is specified for them in the EDMKOVRD DD data set:

This PWXEDM CICS/VSAM Change Capture report includes the following fields:

Init Date
. The date, in mm/dd/yy format, on which the ECCR initialized.

ID
. The ECCR name.

Time
. The time, in hh:mm:ss format, at which the ECCR initialized.

File Name
. The names of the VSAM files that participate in change data capture.

Dataset Name
. The fully-qualified data set names of the VSAM source data sets that participate in change data capture.

Type
. The type of VSAM data set. Valid values are:

KSDS
. A key-sequenced data set.

ESDS
. An entry-sequenced data set.

RRDS
. A relative record data set (RRDS) or variable-length relative record data set (VRRDS).

Path
. An alias path to a VSAM data set.

P/AX
. A CICS alternate index (AIX) path to a VSAM data set.

Warn/Error
. A warning or error flag. Valid values are:

(During PLTPI)
. Indicates the ECCR automatically initialized during the third stage of CICS initialization because you specified the EDMKOPER module name in the PLT initialization list.

NoCapture
. Indicates that the data set is not participating in change capture because the

DSN=dataset_name
,NOCAPTURE

CAPTURE_
vsam_dataset_type
=OFF

override option is specified in the EDMKOVRD DD statement in the CICS region startup JCL or in the data set to which the DD statement points.

Rcv (None)
. Indicates that the VSAM file was defined as RECOVERY(NONE). This RECOVERY option is allowable if you specify CCERR=CONTINUE in the EDMSDIR options module and AllowRecoveryNone in the INITPARM for EDMKOPER, or if you specify CCERR=ABEND in the EDMSDIR options module.

Reg Err
. Indicates that the change capture status of the VSAM data set cannot be determined. The capture registration for the VSAM data set might have an error.
