Can the data storage location be defined?

For instance, can the location of the application be installed in one location on the file system and the location of the directory for the database (db) be defined in another location on the file system?

Let us say that OpenDs has been installed at

C:\Users\james\OpenDS\

Can the db directory be defined as some thing other than

C:\Users\james\OpenDS\db

?

Such as

d:\db

?

I found a link that talks about how to do this.

http://lists.forgerock.org/pipermail/opendj/2011-February/000069.html

A copy and paste from there is as follows:

It is possible to separate the installation directory (i.e. scripts, libraries, etc) from the instance directory (i.e. configuration, db files, logs, etc).

The easiest way to do this that I know if is to modify the contents of the instance.loc file so that it contains the path "/var/opt/opendj". You should then copy the following directories over from your install directory except for the core schema files:

cd echo "/var/opt/opendj" > instance.loc cp -r changelogDb config locks logs db /var/opt/opendj rm /var/opt/opendj/config/schema/*.ldif

You should then be able to do the following once you've configured the server according to your needs (e.g. the LDAP port):

cd /var/opt/opendj /bin/start-ds

If anybody else has anything else to say about this topic I am all ears.

  • The procedure above is actually moving the whole OpenDJ instance to another location, not just the database files. Both are possible, and depends on what you're trying to achieve. Moving DB files can be useful if you have multiple DBs and want to have them on separated disks. – Ludovic Poitou Mar 26 '12 at 14:39

Yes, the DB location may be explicitly set when creating a new Database Backend. However, once defined, it is not possible to change it.

This was discussed in OpenDJ mailing list in December 2011. See the thread starting here: http://lists.forgerock.org/pipermail/opendj/2011-December/001140.html

An alternate possibility, at least on Linux, is to move the db directory to another location and recreate OpenDS/db as a symbolic link to the new location.

Kind regards,

Ludovic.
