Plex Media Server Database Repair Utility
Select
1. Check database
2. Vacuum database
3. Reindex database
4. Attempt database repair
5. Replace current database with newest usable backup copy
6. Undo last successful action (Vacuum, Reindex, Repair, or Replace)
7. Import Viewstate / Watch history from another PMS database
8. Show logfile
9. Exit
Enter choice:
This utility can only operate on PMS when PMS is in the stopped state.
If PMS is running when you startup the utility, it will tell you.
A. Database is malformed (Backups of com.plexapp.plugins.library.db and com.plexap.plugins.library.blobs.db available)
1. Check - (Option 1) - Confirm either main or blobs database is damaged
2. Replace - (Option 5) - Use the most recent valid backup -- OR -- Option 4 (Repair). Check date/time for best action.
-- If Replace fails, use Repair (Option 4)
-- Replace can fail if the database has been damaged for a long time.
3. Reindex - (Option 3) - Generate new indexes so PMS doesn't need to at startup
4. Exit - (Option 8)
B. Database is malformed - No Backups
1. Check - (Option 1) - Confirm either main or blobs database is damaged
2. Repair - (Option 4) - Salavage as much as possible from the databases and rebuild them into a usable database.
3. Reindex - (Option 3) - Generate new indexes so PMS doesn't need to at startup
4. Exit - (Option 8)
C. Database sizes excessively large when compared to amount of media indexed (item count)
1. Check - (Option 1) - Make certain both databases are fully intact (repair if needed)
2. Vacuum - (Option 2) - Instruct SQLite to rebuild its tables and recover unused space.
3. Reinex - (Option 3) - Rebuild Indexes.
4. Exit - (Option 8)
D. User interface has become 'sluggish' as more media was added
1. Check - (Option 1) - Confirm there is no database damage
2. Repair - (Option 4) - You are not really repairing. You are rebuilding the DB in perfect sorted order.
3. Reindex - (Option 3) - Rebuild Indexes.
4. Exit - (Option 8)
E. Undo
Undo is a special case where you need the utility to backup ONE step.
This is rarely needed. The only time you might want/need to backup one step is if Replace leaves you worse off
than you were before. In this case, UNDO then Repair. Undo can only undo the single most-recent action.
Special considerations:
1. As stated above, this utilty requires PMS to be stopped in order to do what it does.
2. *TRICK* - This utility CAN sit at the menu prompt with PMS running.
- You did a few things and want to check BEFORE exiting the utility
- If you don't like how it worked out,
-- STOP PMS
-- UNDO the last action and do something else
-- OR do more things to the databases
3. When satisfied, Exit the utility.
- There is no harm in keeping the database temp files (except for space used)
- ALL database temps are named with date-time stamps in the name to avoid confusion.
4.The Logfile (Option 7) shows all actions performed WITH the timestamp so you can locate intermediate databases
if desired for special / manual recovery cases.
Certain platforms don't provide for each command line access. To support those products, this utility can be operated by adding command line arguments.
Another use of this feature is to automate Plex Database maintenance ( Stop Plex, Run this sequence, Start Plex ) at a time when the server isn't busy
The command line arguments are the same as if typing at the menu.
Example: ./DBRepair.sh 1 4 3 9
This executes: Check, Repair, Reindex, and Exit commands
When exiting, you will be asked whether to keep the interim temp files created during this session. If you've encountered any difficulties or aren't sure what to do, don't delete them. You'll be able to ask in the Plex forums about what to do. Be prepared to present the log file to them.
This sample session shows all the features present. You won't use :
- PMS exclusive access to the databases interlock protecting your data
- Basic checks, vacuum, and reindex
- Full export/import (repair) which also reloads the database in perfect order
- Importing viewstate (watch history) data from another database (an older backup)
- What the log file details for you.
