ALTER-DOMAIN Command
Considerations
•
The ALTER-DOMAIN command is a combination of SERVER commands. When
one of the SERVER commands fails to execute, the ALTER-DOMAIN command
terminates abnormally. However, the SERVER commands executed till the failure
occurs are irreversible.
•
During ALTER-DOMAIN command execution, the server entry is locked such that
no other STOP, START, FREEZE, THAW, ALTER, or ALTER-DOMAIN command
can be issued for this server throughout the domain. When these commands are
issued from PDMCOM, the entry locked error is displayed.
•
After a successful or failed completion of the command, the entry is unlocked. This
enables further STOP, START, FREEZE, THAW, ALTER, or ALTER-DOMAIN
commands to the same server.
Example
Configure a PDMCOM, %pdm, with $PM1, $PM2, $PM3, and $PM4 and then execute
the ALTER-DOMAIN command:
PDMI 1>> open %pdm
PATHMON : \ACS.$PM3
PATHMON : \ACS.$PM1
PATHMON : \ACS.$PM2
PATHMON : \ACS.$PM4
PDMI 2>> alter-domain server svr2,maxservers 3
PATHMON : \ACS.$PM3
$Z11M: SERVER SVR2, FROZEN
$Z11M: SERVER SVR2, STOPPED
\ACS.$Z11L: INFO - *1602* New Request Queuing Started
PATHMON : \ACS.$PM1
$Z11M: SERVER SVR2, FROZEN
PATHMON : \ACS.$PM2
$Z11M: SERVER SVR2, FROZEN
PATHMON : \ACS.$PM4
$Z11M: SERVER SVR2, FROZEN
PATHMON : \ACS.$PM3
$Z11M: SERVER SVR2, THAWED
\ACS.$Z11L: INFO - *1603* New Request Processing Started
PATHMON : \ACS.$PM3
$Z11M: SERVER SVR2, STARTED
PATHMON : \ACS.$PM1
$Z11M: SERVER SVR2, STOPPED
$Z11M: SERVER SVR2, THAWED
$Z11M: SERVER SVR2, STARTED
PATHMON : \ACS.$PM2
$Z11M: SERVER SVR2, STOPPED
Note. When the SERVER commands are issued from PATHCOM, the lock status with the
ACS subsystem is not validated. However, it is recommended that you do not use
PATHCOM.
