MODIFY FDBRPROC

The MODIFY fdbrproc commands are used for an IMS Fast Database Recovery region: to display its status, to stop it, and to recover from failures.

F fdbrproc,DUMP

Format

Read syntax diagramSkip visual syntax diagram>>-F fdbrproc,DUMP---------------------------------------------><

Usage

Use this command to stop IMS Fast DB Recovery functions and request a dump for the region. The region ends with a return code X'0020'.

F fdbrproc,RECOVER

Format

Read syntax diagramSkip visual syntax diagram>>-F fdbrproc,RECOVER------------------------------------------><

Usage

Use this command to initiate an IMS Fast DB Recovery of tracked IMS databases. Use this command, for example, after a time-out during XCF or log surveillance.

This command is not accepted if an IMS Fast DB Recovery region is currently starting or if it is recovering databases.

F fdbrproc,STATUS

Format

Read syntax diagramSkip visual syntax diagram>>-F fdbrproc,STATUS-------------------------------------------><

Usage

Use this command to display status for an IMS Fast DB Recovery region. The output displayed includes the following information:

PHASE
This field indicates the phase of the Fast DB Recovery region. The following are possible values for the phase:
LOG-TIME
Time of the log record currently being processed by the Fast DB Recovery region. The length of time the Fast DB Recovery region lags behind IMS in reading the log is the difference between the current time, as shown by the time stamp, and the log time. This field displays N/A during FDBR initialization.
ACT-ID
The IMSID of the IMS subsystem that Fast DB Recovery is tracking. This field displays N/A during FDBR initialization.
GROUPNAME
XCF group name used for XCF monitoring. This field displays N/A during FDBR initialization.
TIMEOUT
XCF timeout value. This field displays N/A during FDBR initialization.
AREA01
The sharing level for DEDB areas. The following are possible values for AREA01:

You specify the sharing level for AREA01 in the DFSFDRxx member of IMS.PROCLIB.

| |
SVSOOPEN
|
Specifies that all areas requiring redo processing in an FDBR |system will be serially processed. This option is ignored for /ERE |and XRF TKO processing. It is used to reduce the number of structures |being allocated by FDBR for redo processing. |
| |
FPBUFF
|
Specifies that the control blocks for Fastpath DEDB processing |are to be gotten from the FDBR private region rather than ECSA. | |

The LOCAL parameter is specified in the DFSFDRxx member. If |this option is selected, the control blocks for DEDB processing |are taken from the FDBR control region private storage.

| |

If this option is not specified, the control blocks for DEDB |processing are taken from ECSA. This is the default.

|

|Example:  |

|
F FDR1,STATUS
|DFS000I PHASE: TRACKING  LOG-TIME: 17:48:41  FDR1
|DFS000I     ACT-ID: SYSS3    GROUPNAME: FDRSYS3  FDR1
|DFS000I TIMEOUT: 060 SEC AREA01: NORECOV     FDR1
|DFS000I SVSOOPEN: SERIAL FPBUFF: LOCAL       FDR1

F fdbrproc,STOP

Format

Read syntax diagramSkip visual syntax diagram>>-F fdbrproc,STOP---------------------------------------------><

Usage

Use this command to stop an IMS Fast DB Recovery region. The region ends with a return code X'0020'.

F fdbrproc,TERM

Format

Read syntax diagramSkip visual syntax diagram>>-F fdbrproc,TERM---------------------------------------------><

Usage

Use this command to stop IMS Fast DB Recovery tracking activity.

This command is not accepted if an IMS Fast DB Recovery region is currently starting or if it is recovering databases.
