One command database upgrade on ODA

By | Database Administration & Monitoring | 4 Comments

The 12.2 finally arrived on ODA and is now available on all generations. Modern ODAs are now supporting, and database engines, and these 3 versions can work together without any problem. You probably plan to upgrade some old databases to the latest engine, at least those still running on 11.2. As you may know, 11.2  is no more supported with premier support since January 2015: it’s time to think about an upgrade….

ODA – VLAN Management

By | Database Administration & Monitoring | 2 Comments

Virtual Local Area Network (VLAN) have become since several years a standard in enterprise class networks.

Recommended DB Parameters on the Oracle Database Appliance (ODA)

By | Database Administration & Monitoring, Database management, Hardware & Storage, Oracle | 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…

By Franck Pachot . 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.

By | Database Administration & Monitoring | 5 Comments

It also has the possibility to create a database, but this is for next blog post. In this post I’ll show which information are displayed once the ODA is installed.
