rcdmqimg (record media image)

Purpose

Use the rcdmqimg command to write an image of an object, or group of objects, to the log for use in media recovery. Use the associated command rcrmqobj to recreate the object from the image.

You use this command with an active queue manager. Further activity on the queue manager is logged so that, although the image becomes out of date, the log records reflect any changes to the object.

Syntax

Required parameters

GenericObjName

The name of the object to record. This parameter can have a trailing asterisk to record that any objects with names matching the portion of the name before the asterisk.

This parameter is required unless you are recording a queue manager object or the channel synchronization file. Any object name you specify for the channel synchronization file is ignored.

-t ObjectType

The types of object for which to record images. Valid object types are:

	nl or namelist	Namelists
	prcs or process	Processes
	q or queue	All types of queue
	ql or qlocal	Local queues
	qa or qalias	Alias queues
	qr or qremote	Remote queues
	qm or qmodel	Model queues
	qmgr	Queue manager object
	syncfile	Channel synchronization file
	ctlg or catalog	An object catalog
	authinfo	Authentication information, for use with Secure Sockets Layer (SSL) channel security
	* or all	All the above

Note:

When using WebSphere MQ for UNIX systems, you need to prevent the shell from interpreting the meaning of special characters, for example, *. How you do this depends on the shell you are using, but might involve the use of single quotation marks, double quotation marks, or a backslash.

Optional parameters

-m QMgrName: The name of the queue manager for which to record images. If you omit this, the command operates on the default queue manager.
-z: Suppresses error messages.
-l: Writes messages containing the names of the oldest log files needed to restart the queue manager and to perform media recovery. The messages are written to the error log and the standard error destination. (If you specify both the -z and -l parameters, the messages are sent to the error log, but not to the standard error destination.)
When issuing a sequence of rcdmqimg commands, include the -l parameter only on the last command in the sequence, so that the log file information is gathered only once.
