Command Overview
COPYAUDIT
This command is only for use with the triple contingency feature.
If the primary system fails, you must execute two takeovers: one on each backup system
involved in the triple contingency protocol. Upon successful completion of both
takeovers, the databases on the two backup systems will almost assuredly not be
identical: one of the extractors will have been further ahead of the other in its RDF
processing when the failure occurred.
The COPYAUDIT command copies missing audit information from the backup system
that was further ahead in its RDF processing (had the most amount of audit data) to the
system that was further behind (had the least amount of audit data).
REMOTESYS name
specifies the name of the backup system that has the most audit information (that
was further ahead in its RDF processing).
REMOTECONTROLSUBVOL subvol
specifies the name of the RDF control subvolume on the remote system.
Where Issued
Backup system only (the backup system that has the least amount of audit information).
Security Restrictions
You can issue the COPYAUDIT command only if you are a member of the super-user
group and have remote passwords on both systems.
RDF State Requirement
After an RDF takeover operation has completed successfully on both backup systems,
you must issue the COPYAUDIT command while RDF is stopped.
Usage Guidelines
Upon successful completion of the two takeovers, examine the EMS event log on both
backup systems for a 735 message. That message, which follows the 724 message in the
log, specifies the last position in the MAT that was seen by the receiver process.
Compare the MAT positions in the two 735 messages and determine which of the two
systems was further behind in its RDF processing when the failure occurred (that is,
which system had received the least amount of audit data from the extractor by the time
the primary system was lost). Then issue a COPYAUDIT command on the system that
is behind, specifying the name of the other backup system and its RDF control
subvolume.
