odacli create-database error DCS-10802: Insufficient disk space on file system: database

By | Database Administration & Monitoring, Database management, Operation systems, Oracle | No Comments

Introduction I was reimaging an X6-2M ODA after various patching troubles, and everything was fine. After several databases created, the next ones could no more be created. DCS-10802: Insufficient disk space on file system: database. Expected free space (MB): {1}, available space (MB): {2} I’ve spent some time on it, and finally found the cause of the problem. And the solution. Context After successfully reimaged an X6-2M ODA with 18.5, and applied the patch for…

Adding a dbvisit standby database on the ODA in a non-OMF environment

By | Database Administration & Monitoring | No Comments

I have recently been working on a customer project where I had been challenged adding a dbvisit standby database on an ODA X7-2M, named ODA03. The existing customer environment was composed of Oracle Standard 12.2 version database. The primary database, myDB, is running on server named srv02 and using a non-OMF configuration. On the ODA side we are working with OMF configuration. The dbvisit version available at that time was version 8. You need to…

Connecting to ODA derby database

By | Database Administration & Monitoring | No Comments

ODA light (ODA X7-2S, X7-2M, X8-2S, X8-2M) come with an internal derby database to manage ODA metadata. From time to time, there is a need to check or update some information within it, as for example when facing database deletion issue. I would like to strongly advise that updating manually the ODA repository should only be done after getting Oracle support guidance and agreement to do so. Neither the author (that’s me 🙂 ) nor…

Migrating Oracle database from windows to ODA

By | Database Administration & Monitoring | 2 Comments

Nowadays I have been working on an interesting customer project where I had to migrate windows oracle standard databases to ODA. The ODAs are X7-2M Models, running version 18.5. This version is coming with Red Hat Enterprise Linx 6.10 (Santiago). Both windows databases and target ODA databases are running PSU 11.2.0.4.190115. But this would definitively also be working for oracle 12c and oracle 18c databases. The databases are licensed with Standard Edition, so migrating through…

ODA X8-2: the new generation

By | Database Administration & Monitoring, Hardware & Storage, Oracle | 2 Comments

Introduction ODA X7-2 marked the maturity of the Oracle Database Appliance evolution, with 3 models suitable for nearly all customers using Oracle databases. The X7-2M was my favorite, with a lots of cores available (and restrainable), enough memory for dozens of databases, and strong storage performance and capacity (with a maximum of 50TB RAW NVMe). And taking up only 1U of space in your rack. Today, 2 years later, Oracle just introduced the new generation…

Moving oracle database to new home on ODA

By | Database Administration & Monitoring | No Comments

Moving database to new ORACLE_HOME is a common dba task. Performing this task on an ODA will need an additional step knowing ODA Lite is using an internal Derby database for the metadata. ODA HA will not be a problem here, knowing we do not have any Derby database. Through this blog I would like to give you some guidance and work around to move database to a new home (of same major release). In…

Patching or reimaging your ODA?

By | Database Administration & Monitoring, Hardware & Storage, Operation systems, Oracle | No Comments

Introduction One of the key features of the ODA (Oracle Database Appliance) is the ability to patch the entire stack every three months, the goal being to keep all the components up-to-date. Most of the customers won’t patch so often, but one patch a year is quite a good average. But when comes the time for patching, comes the time for anxiety for the DBA. And it’s totally justified. Why ODA patching can eventually be…

Why ODA reimaging doesn’t work on the first try?

By | Database Administration & Monitoring, Database management, Oracle | No Comments

Introduction Reimaging an ODA is a good practice for a lot of reasons. To make your ODA cleaner if it’s running for many years and if you patch regularly. To simplify patching because if you’re late you could have to apply multiple intermediate patches to reach the target version. Or simply because you need to change the configuration (for example network configuration) and you want to make things clean, and be sure that future patches…
