Using H2 storage in oxd#

H2 configuration in oxd#

The storage used in oxd can be either H2 or Redis. To use H2 database as storage in oxd-server we need to follow below step:

  • Log into Gluu CE server (oxd is installed in chroot of CE).

  • In /opt/oxd-server/conf/oxd-server.yml file of installed oxd-server set following parameters.

    storage: h2
storage_configuration
  dbFileLocation: /opt/oxd-server/data/oxd_db

By default, the oxd-server persists data inside H2 embedded database. On your disk, it should look like an oxd_db.mv.db file. In dbFileLocation parameter of oxd-server.yml the path is set where oxd_db.mv.db is generated.

H2 tools to view/edit data in H2 DB#

The oxd-server persists data inside H2 embedded database, it should look like an oxd_db.mv.db file on disk. You can use any convenient database viewer to view/edit data inside the database. We recommend to use the browser-based viewer H2:

  • Download http://www.h2database.com/html/download.html
  • Run it (in "Platform-Independent zip" case it is as simple as hitting h2.sh or h2.bat)

In the browser, you will see connection details; please specify details as in oxd-conf.json file. If all is filled correctly, upon "Test Connection" you should see a "Test successful" message like in the screenshot below:

After hitting the "Connect" button, you will be able to view/modify data manually. Please be careful not to corrupt the data inside. Otherwise, oxd-server will not be able to operate in its normal mode.

We can use Sql clients like DBeaver to view and edit data in database. The steps are:

  1. Download, install and start DBeaver.
