The OpenLDAP Directory Service service terminated with service-specific error 21 (0x15).

Biasanya error seperti ini timbul setelah server crash, gejalanya service OpenLDAP tidak bisa dijalankan. Cara mengatasinya lakukan recover databasenya.

Rumusnya seperti ini:

db_recover [-ceVv] [-h home] [-P password] [-t [[CC]YY]MMDDhhmm[.SS]]]

-c
Perform catastrophic recovery instead of normal recovery.
-e
Retain the environment after running recovery. This option will rarely be used unless a DB_CONFIG file is present in the home directory. If a DB_CONFIG file is not present, then the regions will be created with default parameter values.
-h
Specify a home directory for the database environment; by default, the current working directory is used.
-P
Specify an environment password. Although Berkeley DB utilities overwrite password strings as soon as possible, be aware there may be a window of vulnerability on systems where unprivileged users can see command-line arguments or where utilities are not able to overwrite the memory containing the command-line arguments.
-t
Recover to the time specified rather than to the most current possible date. The timestamp argument should be in the form [[CC]YY]MMDDhhmm[.SS] where each pair of letters represents the following:
CC
The first two digits of the year (the century).
YY
The second two digits of the year. If “YY” is specified, but “CC” is not, a value for “YY” between 69 and 99 results in a “YY” value of 19. Otherwise, a “YY” value of 20 is used.
MM
The month of the year, from 1 to 12.
DD
The day of the month, from 1 to 31.
hh
The hour of the day, from 0 to 23.
mm
The minute of the hour, from 0 to 59.
SS
The second of the minute, from 0 to 61.
If the “CC” and “YY” letter pairs are not specified, the values default to the current year. If the “SS” letter pair is not specified, the value defaults to 0.

-V
Write the library version number to the standard output, and exit.
-v
Run in verbose mode.

Contoh:

C:\OpenLDAP>db_recover -v -h C:\OpenLDAP\CNOOCSES -t 200905291609
Finding last valid log LSN: file: 50 offset 8923232
Recovery starting from [42][48670]
Recovery complete at Mon Jul 13 08:21:47 2009
Maximum transaction ID 800201f3 Recovery checkpoint [50][8923140]

C:\OpenLDAP> : Directory dimana file db_recover.exe berada

C:\OpenLDAP\Data : Directory dimana file database OpenLDAP berada (cirinya berextension *.bdb)

Note:

Data yang akan direcover yaitu data yang pada terakhir kalinya OpenLDAP berjalan normal.

Kemudian start service OpenLDAP…Insya Allah jalan….
