-=== How to recover from a corrupted ODB ===
+Instructions moved to [[FAQ]]
-* Stop your front-ends, [[mlogger]], [[mhttpd]], etc.
-* Remove the shared memory associated to ODB buffer. Find the shared memory segment by doing
- ls -l /dev/shm
-then remove the segment that will be something like /dev/shm/*_test_ODB_SHM
-* Move the old ODB files. These will be in the location given by [[Exptab]], e.g. ~/online
- cd online
- mv .ODB.SHM .ODB.SHM.BAD
-* Restart ODB with larger size using [[odbedit]] e.g.
- odbedit -s 100000000
-* Reload the last saved ODB dump you have (see [[ODB#Save and reload the ODB|save and reload the ODB]]). These dumps are typically called something like 'online/history/*.xml'.
-So from  {{Utility|name=odbedit}} you do something like
- odbedit> load history/run00071.xml
-* Your ODB should now be fixed.
-Note that sometimes it seems that you also need to remove the buffers associated with the system messages (called SYSMSG) as well as the buffers associated with the ODB.
