ALTER DUMPS
ON changes the entries for the specified dumps to indicate you no longer need
these dumps. Use this option when recent dumps exist in the catalog but have
been damaged or marked as deleted.
If the catalog shows only one valid dump for a given serial number, and you
release that dump, the entire dump serial number is removed from the catalog.
SERIAL serial-number
directs this ALTER DUMPS command to change the catalog entries for only the
dumps with the specified serial number. You can obtain information about dump
serial numbers by using the INFO DUMPS command, or by examining reports
produced for an audit dump or online dump.
Security Restrictions
You can issue the ALTER DUMPS command only if you are a member of the super
user group.
TMF State Requirement
Before you can enter the ALTER DUMPS command, TMF must be started.
Usage Guidelines
Use the ALTER DUMPS command to change the INVALID flag or the RELEASED flag
for one or more dump entries in the catalog. As an example, if you deleted a file that
also caused a dump to be deleted from the TMF catalog, you could use the ALTER
DUMPS command to correct the catalog entry to recover the file.
A database file is unavailable if it is purged or if the FUP ALTER command is used to
assign the NO AUDIT option to the file. If all files in a dump are unavailable, all
records for the dump are removed from the catalog.
After TMF’s TMFSERVE process completes the changes requested by the ALTER
DUMPS command, it searches the TMF catalog for other candidate dump entries that
might require changing. This search might take a long time, perhaps even appearing
like TMFSERVE is in an endless loop. If you encounter this situation but can
determine that all relevant changes have been applied, you can stop the TMFSERVE
process.
Examples
The following ALTER DUMPS command changes the catalog entry for a dump to
indicate that the dump is not available for use by file recovery. The dump is identified
by Serial Number 137.
