Provide means to ignore selected DB recovery errors
When recovering a damaged database, it is sometimes necessary to ignore constraint errors resulting from damaged indexes.
This update provides command line options to support this:
1. -i or -f - Ignore DB check errors / Force acceptance
2. -p - When importing viewstate from another DB, purge duplicate counts.
(Use with extreme caution).

|

v1.0.9
|

|
||||
- When recovering a damaged database, it is sometimes necessary to ignore constraint errors resulting from damaged indexes.
|
||||
|
||||
This update provides command line options to support this:
|
||||
|
||||
1. -i or -f - Ignore DB check errors / Force acceptance.
|
||||
2. -p - When importing viewstate from another DB, purge duplicate counts.
|
||||
(Use with extreme caution).
|
||||
|
||||
Usage: DBRepair.sh [Options] commands
|
||||
Example: DBRepair.sh -i -p start auto stop exit
|
||||
|
||||
|
||||
v1.0.8
|
||||
- Require root UID (super user).
|
||||
Requiring root UID gives the script the privilege necessary to set the database ownership
