Command Overview
ALTER
The ALTER command changes the setting of the specified parameter in the RDF
configuration file to the supplied value.
extractor-option, monitor-option, purger-option, global-option,
receiver-option, netsynch-option, and updater-option
are described under the SET RDF, SET EXTRACTOR, SET MONITOR,
SET RECEIVER, SET PURGER, SET RDFNET, and SET VOLUME commands,
respectively.
Where Issued
Primary system only.
Security Restrictions
You can issue the ALTER command only if you are a member of the super-user group.
RDF State Requirement
While RDF is running, the only configuration parameters you can alter are the log file,
the purgetime, the RDF updaterdelay, and the priority of each RDF process. The RDF
updateropen can be changed with RDF running but updating stopped. To change the
setting of any other parameter, you must first stop RDF.
Usage Guidelines
Before entering the ALTER command, you can display the current configuration
parameters with the INFO RDF command. After entering ALTER, you can confirm
your changes by again entering INFO RDF.
If you use an ALTER RECEIVER command to change the EXTENTS parameter, the
change will occur on the next RDF image file rollover, unless RDF has never been
started since its last reinitialization.
Although you can use the SET RECEIVER RDFVOLUME command to specify the disk
volume used for the master image trail, you cannot respecify this volume by entering
an ALTER RECEIVER RDFVOLUME command. To change this volume, you must
ALTER {RDF global-option }
{MONITOR monitor-option }
{EXTRACTOR extractor-option }
{RECEIVER receiver-option }
{PURGER purger-option }
{RDFNET netsynch-option }
{VOLUME updater-option }
