Documentum – Change password – 7 – DB – Schema Owner

By | Entreprise content management | No Comments

In this serie, I completed the passwords I wanted to talk about on the Content Server. Therefore in this blog, I will talk about the only Database Account that is relevant for Documentum: the Database Schema Owner. Since there are a few steps to be done on the Content Server, I’m just doing everything from there… In this blog, I will assume there is one Global Registry (GR_DOCBASE) and one normal Repository (DocBase1). Each docbase…

Recommended DB Parameters on the Oracle Database Appliance (ODA)

By | Database Administration & Monitoring, Database management, Hardware & Storage | No Comments

When creating a DB on the ODA using # oakcli create database -db <db-name> a template is used to set a couple of DB parameters like e.g. _datafile_write_errors_crash_instance=FALSE _db_writer_coalesce_area_size=16777216 _disable_interface_checking=TRUE _ENABLE_NUMA_SUPPORT=FALSE _FILE_SIZE_INCREASE_INCREMENT=2143289344 _gc_policy_time=0 _gc_undo_affinity=FALSE db_block_checking=’FULL’ db_block_checksum=’FULL’ db_lost_write_protect=’TYPICAL’ filesystemio_options=’setall’ parallel_adaptive_multi_user=FALSE parallel_execution_message_size=16384 parallel_threads_per_cpu=2 use_large_pages=’ONLY’ In recent projects I saw a couple of DBs running on ODA, which did not have (all) those parameters set, because the DBs were migrated from a non-ODA-platform and the customer took over…

ODA X6 installation: re-image

By | Database management | No Comments

The Oracle Database Appliance is shipped with a bare-metal installation which may not be the latest version. You may want to have it virtualized, or get the latest version to avoid further upgrade, or install an earlier version to be in the same configuration as another ODA already in production. The easiest for all cases is to start with a re-image as soon as the ODA is plugged. This post is not a documentation, just…

Getting Solaris 8 x86 up and running in Virtual Box

By | Database Administration & Monitoring | No Comments

As this project is going to start soon and I learned that there is a x86 version of Solaris 8, today I thought it would be great if I can get a test setup up and running. First issue: Where to get the Solaris 8 distribution from. This turned out be quite easy, there is a support note which links to all the releases: Where to download Oracle Solaris ISO images and Update Releases (Doc…

You do use the Oracle Trace File Analyzer, don’t you?

By | Database Administration & Monitoring | One Comment

When you do not know what the Oracle Trace File Analyzer (tfa) is or you have heard about it but you don’t know what it is for then you probably should read this, especially when you are working in clustered Oracle environments. You know, Oracle loves to create plenty of trace files in various places (yes, this got much better with the Automatic Diagnostics Repository(ADR)). Now imagine you have a cluster and something goes wrong,…

Workaround for bug 19566227/20563128 doing Cross Platform Migration (MOS Note 1389592.1)

By | Database Administration & Monitoring, Database management | One Comment

In a project I have to move an Oracle 11.2.0.4-DB (around 7TB in size) from Sparc Solaris (called Source in the remainder of this Blog) to Linux x86-64 (called Target in the remainder of the Blog). I.e. a platform migration from Big Endian to Little Endian. A good method to do that is described in My Oracle Support Note 1389592.1: 11G – Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup Basically I copy the…
