Command Overview
ALTER
The ALTER command changes the setting of the specified parameter in the RDF
configuration file to the supplied value.
global-option, extractor-option, monitor-option,
receiver-option, purger-option, netsynch-option,
trigger-option and updater-option
are described under the SET RDF, SET EXTRACTOR, SET MONITOR,
SET RECEIVER, SET PURGER, SET RDFNET, SET TRIGGER, and SET
VOLUME commands, respectively.
trigger-type
is REVERSE or TAKEOVER. This command parameter alters a trigger that has
already been added to the RDF configuration.
Where Issued
These commands can be issued only at the primary system, except ALTER TRIGGER,
which can be issued at the backup system if the primary system is not available.
Security Restrictions
You can issue the ALTER command if you are a member of the super-user group.
ALTER {RDF global-option }
{EXTRACTOR extractor-option }
{MONITOR monitor-option }
{RECEIVER receiver-option }
{PURGER purger-option }
{RDFNET netsynch-option }
{TRIGGER {trigger-type } {trigger-option } }
{VOLUME updater-option }
Note. If you alter one or more trigger attributes on the backup system while the primary
system is down and the primary system once again becomes available, you should perform the
same alter operation(s) on the primary system before starting RDF. If you don’t do that the
changes are lost because, when it starts, RDF automatically copies configuration information
from the primary system to the backup system.
