Infrastructure at your Service
When a customer wanted to take the challenge to migrate an oracle database 9.2.0.6 (the prehistory in the Oracle world) to Oracle 19c using Oracle GodenGate, I saw more problems than add value for different reasons: Â Oracle 9.2.0.6 database is out of support (final 9.2 patch was Oracle 9.2.0.8). The customer Operating Systems was AIX 7.4 and only Oracle GoldenGate 11.1.1.1.2 for Oracle 9.2 for AIX 5.3 is available on https://edelivery.oracle.com. The Patch 13606038: ORACLE…
In the last post we had a look at the installation and setup of pg_auto_failover. We currently have one primary cluster and two replicas synchronizing from this primary cluster. But we potentially also have an issue in the setup: The monitor is running beside the primary instance on the same node and if that nodes goes down the monitor is gone. What happens in that case and how can we avoid that? We also did…
In a previous blog I talked about the domain creation, we saw at the end that some server groups and servers are created by default which usually are not what we need. Through this blog, I will show you how to clean this unneeded configuration and how to configure your domain according to your defined architecture.
I had a case today where all Documentum components were up and running, including D2 but while accessing its login page, the repositories wouldn’t appear and a message “An unexpected error occurred. Please refresh your browser” would pop-up in the lower-right corner and disappear quickly. Refreshing the browser or opening a private window wouldn’t do anything. In such cases, of course the first thing to do would be to make sure the docbroker and repositories…
I got the question if it is possible to have a the WebLogic JDBC Data Source to be resolved by an LDAP entry. The answer is yes; since WebLogic 12.2.1.3 a JDBC connection pool URL declaration can point to an LDAP entry. This can be done by simply editing an existing JDBC data source. jdbc:oracle:thin:@ldap://vm01.dbi-workshop.com:1389/cn=orcl,cn=OracleContext,dc=DatabaseConnection,dc=com Of course the LDAP server needs to have been configured to store the TNS entries. I explained how to do…
Using a LDAP server to store the TNS connection strings can be a single point of declarations for all client tools. Note that it can be a single point of failure too, thus, a High Availability LDAP configuration is recommended for production use. In my case, I was interested in using a LDAP as TNS connections repository for the WebLogic Domains Data-Source connections. I used a Oracle Unified Directory (OUD). The first step is to…
Everybody familiar with Documentum knows that just starting the JBoss/WildFly hosting an IndexAgent isn’t really enough to have the indexing working: the IndexAgent must be started from the UI (or via DA or via the job or via iapi or automatically via the Repository startup or …). Starting the IA in “normal mode” is usually something that takes a few seconds. I faced a few times an IA that apparently didn’t want to start: whenever…
In relation to my previous blog about custom facets not showing up after full reindex, a customer was doing a migration that just completed. After the full reindex, there were no facets because of what I explained in the blog. Knowing that the online rebuild is normally faster than a full reindex, I helped to start this operation but after a little bit more than a day of processing, it failed on a document. The…
Beginning of the year, while performing a migration from a Documentum 7.3 environment on VM to Documentum 16.4 on Kubernetes, a customer had an issue where their custom facets weren’t showing up on D2 after a full reindex. At the end of the migration, since xPlore has been upgraded as well (from xPlore 1.5 to 16.4, from VM to K8s), then a full reindex has been executed so that all the documents are indexed. In…
I wrote this blog in conjunction with the one about the Solr Sharding – Concepts & Methods a year ago and it was 95% completed but then I had other stuff to do and just forgot I didn’t publish it. It might be a little bit late but well, better late than never… It will complete the overview I wanted to share around the Alfresco Clustering and in particular around the Solr Sharding. In this…
