Table 7.7 . db2index Opt ions

Option Description

-n backendInstance Gives the name of the instance to be reindexed.

-s includeSuffix Gives suffixes to be included or the subtrees to

be included if -n has been used.

-t attributeName{:indextypes(:mathingrules)} Names of the attributes to be reindexed.

Optionally, this can include the index type (eq,

pres, sub, approx) and a matching rule OID.

-T vlvAttributeName Gives the names of the VLV attributes to be

reindexed. T he name is the VLV index object's

common name in cn=config.

7.3.6. dbve rify (Checks for Corrupt Data bases)

Verifies the backend database files. If the server crashes because of a corrupted database, this

command can be used to verify the integrity of the different database files to help isolate any problems.

IMPORTANT

Never run dbverify when a modify operation is in progress. This command calls the

BerkeleyDB utility db_verify and does not perform any locking. This can lead to data corruption

if the script is run at the same time as a modify. If that occurs, an entry will be recorded in the

error log:

DB ERROR: db_verify: Page 3527: out-of-order key at entry 42

DB ERROR: db_verify: DB->verify: db/mstest2/uid.db4: DB_VERIFY_BAD: Database

verification failed

Secondary index file uid.db4 in db/m stest2 is corrupted.

Please run db2index(.pl) for reindexing.

Run db2index -t uid to avoid rebuilding all of the indexes or export and reimport all of the

databases using db2ldif and ldif2db.

dbverify is a shell script wrapper of verify-db.pl to set the appropriate library path.

dbverify [ -a /path/to/database_directory ]

Options

Table 7.8 . dbverify Options

Option Description

-a path Gives the path to the database directory. If this

option is not passed with the verify-db.pl

command, then it uses the default database

directory,

/var/lib/dirsrv/slapd-instance_name/db.

For information on the equivalent Perl script, see Section 7.4.21, “verify-db.pl (Check for Corrupt

Databases)”.

7.3.7. ds_removal

The ds_removal tool removes a single instance of Directory Server. The server instance usually must

be running when this script is run so that the script can bind to the instance. It is also possible to force

the script to run, which may be necessary if there was an interrupted installation process or the instance

is corrupted or broken so that it cannot run.

When the instance is removed, it is shutdown and all of its configuration files are removed. Certificate

database files, like cert8.db and key3.db, are not removed, so the remaining instance directory is

renamed removed.slapd-instance.
