OUD 11.1.2.3 – How to recover a lost entry in a replicated OUD environment

By | Database Administration & Monitoring | No Comments

By accident, it could happen that someone dropped an OUD entry in your replicated environment and of course, the entry is deleted on all replicas as well. And besides that, you got no logical ldif export of your OUD. Not a good situation, but if you have a done regular backups, there is a way out without resetting the whole OUD environment to an old timestamp. The idea is, to create a second empty OUD…

OUD 11.1.2.3 – Patch 25840309: OUD BUNDLE PATCH 11.1.2.3.170718

By | Database Administration & Monitoring | 3 Comments

A new OUD bundle patch was release at the 18th of July 2017, and this gives me the opportunity to show how fast an OUD can be patched, if configured correctly. In case you have an OUD multi master replication with a load balancer virtual IP on top, then zero downtime patching is possible. This is the configuration that I usually recommend. Not only for high availability, but also for maintenance. A typical OUD installation…

OUD 11.1.2.3 – ODSM Session Timeout

By | Application integration & Middleware, Database Administration & Monitoring | No Comments

The ODSM is a quite powerful tool for managing the Oracle Unified Directory, and quite a lot of default settings are very reasonable. But there is one that disturbed me from the beginning. It is the ODSM Session Timeout. You might see a message like the following. Or maybe this one. It just says, that the page will expire unless a response is received within 2 minutes. Doing some complex searches or similar stuff often…

OUD 11.1.2.3 – How to create an OUD Start/Stop/Status script on Oracle Linux 6

By | Database Administration & Monitoring | No Comments

One of the questions that pops up immediately, after you have installed your OUD successfully is how to integrate it into the automatic startup routines of the OS. My example here show how to do it on Oracle Linux 6. On Oracle Linux 7 it looks a little different. Fortunately, Oracle delivers a script called “create-rc-script”, which can be found in your asinst home directory. It lets you specify the user name under which the…

OUD – Oracle Unified Directory 11.1.2.3, How to change the Java version of OUD 11.1.2.3 with Weblogic and ODSM

By | Application integration & Middleware, Database Administration & Monitoring | No Comments

In this blog, I would like to show how to change the Java version used by OUD and WebLogic, in case you use the ODSM. The OUD (Oracle Unified Directory) is written purely in Java, not like OID for example, and so, it relies heavily on your installed Java version. From a security point of view, updating the Java version is a task that you might do frequently and you want to do it as…

OUD – Oracle Unified Directory 11.1.2.3, Oracle generates more and more LDAP lookups with every release

By | Database Administration & Monitoring | One Comment

After installing OUD some time ago, I was doing some tests to see how it performs, and as long as I do ldap searching on the command line it looks very good. I am running Unified Directory 11.1.2.3.170117 (latest PSU), just for the protocol and I use the OUD only for TNS resolving and nothing else. However, Oracle clients are not connecting with “ldapsearch”, they are using “sqlplus” and the TNS name is resolved automatically…

OUD – Oracle Unified Directory 11.1.2.3 Tuning, It is not always the servers fault

By | Database Administration & Monitoring | No Comments

The default configuration which is shipped with OUD is not meant to be ready for enterprise usage. The default settings of OUD are targeted at evaluators and developers who run equipment with limited resources, and so it is quite likely that you run into performance issues if you don’t change anything, before going into production. The OUD performance depends on a lot of things like Network configuration/routing/firewalls/bonding OUD version and configuration (Replication, TLS) Java version…

OUD – Oracle Unified Directory 11.1.2.3 Backups Tips and Tricks

By | Database Administration & Monitoring | No Comments

Backing up an OUD consists of several components The OUD software itself The OUD back end data The OUD configuration The OUD logical export as a ldif file However, in this post I would like to take a closer look at the back end data. Unlike the old OID, the OUD directory server uses the Berkeley DB Java Edition (JE) as its primary back end. The OUD backup command allows you to backup all back…
