Be aware of what you can do to optimize availability and
performance of disk stores.
- When you start your
system, start all the members that have persistent tables in parallel. Create
and use startup scripts for consistency and completeness.
- Shut down your system using the gfxd
shut-down-all command. This is an ordered shutdown that shuts down
all data stores and accessors, but leaves locators running. When
shutting down an entire system, a locator should be the last member to shut down
(after all data stores have successfully stopped).
- Decide on a file
compaction policy and, if needed, develop procedures to monitor your files and
execute regular compaction.
- Decide on a backup
strategy for your disk stores and follow it. You can back up by copying the
files while the system is offline, or you can back up an online system using
gfxd backup command.
- If you drop or alter any
persistent table while your disk store is offline, consider synchronizing the
tables in your disk stores.
