DSMSERV EXTEND LOG (Emergency Log Extension)

Use this command to extend the size of the recovery log when you need additional log space to restart the server. After the server is running, you can do the following:

Syntax

>>-DSMSERV EXTEND LOG--volume_name--megabytes------------------><
 

Parameters

volume_name (Required)
Specifies the name of a new, formatted volume available for use as the recovery log extension.

megabytes (Required)
Specifies the size, in megabytes, of the new volume. The size must be a multiple of 4MB and 1MB less than the size of the volume specified in the volume_name parameter. For example, if the volume is 5MB, specify a value of 4.

Examples

Task

The server halts, and there is not enough recovery log space to restart. After you have formatted a 21MB volume named ADSM.LOGX, extend the recovery log using the new volume.
