FMDSIZE
starting. Lowering the parameter increases the time for the complete processor
memory to be returned to system operation.
Example
This example sets the FMD post-reload PRDUMP priority to 150:
FMDPOSTPRIORITY 150
FMDSIZE
The FMDSIZE command sets the initial dump size in megabytes.
Initial-Partial-Dump-Size
is the initial partial dump size in megabytes. The default is 2 gigabytes. The
maximum value is 3 gigabytes. The minimum value is 1 gigabyte.
Guidelines
•
You can use the abbreviation fs in place of FMDSIZE.
•
The default value has been tuned by software development to provide the best
balance of information needed for rediscovery, the best speed of the dump, and
the appropriate amount of memory to return to the system as soon as possible.
•
ALTERNATE VOLUMES ALLOWED must have been specified on the
DUMPVOLUME command to allow use of the volumes specified in the
ALTERNATE-VOLUMES command.
Example
This example sets the fast dumping initial dump size to 1 gigabyte:
FMDSIZE 1000
FMDUMP
This command activates the FMD process within TFDS. This feature is OFF by default
but is automatically enabled at TFDS startup if any processors (that are online) within
the system have a memory size greater than two gigabytes.
FMDSIZE Initial-Partial-Dump-Size
FMDUMP { ON | OFF }
