Am I a DBA 3.0 or just an SQL*DBA?

By | Oracle | No Comments

There are currently a lot of new buzz words and re-namings which suggest that our DBA role is changing, most of them escorted with a #cloud hashtag. Oracle Technology Network is now called Oracle Developer Community. Larry Ellison announced the database that does not need to be operated by humans. And people talking about the death of DBA, about the future of DBA, about DBA 3.0,… Those are all generalizations and universal statements, and I…

Oracle Cloud: script to stop all PaaS services

By | Cloud, Oracle | No Comments

With metered cloud services, keeping all your instances running may become expensive. The goal is to start them only when you need them. Here is a script that stops all instances you have on the Oracle Cloud Service PaaS. You can schedule it for example to stop them at the end of the business day, or when they are not active for a long time. The scripts use the REST API called with curl, JSON…

Google Cloud Platform instances and Oracle Database

By | Cloud, Database Administration & Monitoring | No Comments

When it comes to choose a cloud instance to run Oracle Database, you want to be able to run your workload on the minimum CPU cores. This is why in a previous post I measured how many logical reads per seconds can be achieved with a SLOB workload, on AWS which is often the first considered, and will probably do it on Azure in the future. I did the same on the Oracle Cloud which…

Oracle 12cR2, RAC, Cloud, ACFS, PDB thin clones and asmadmin

By | Cloud, Database Administration & Monitoring | No Comments

In the Oracle Public Cloud, fast provisioning gets all its meaning when creating a RAC database service: in one hour you can get an operational highly available multitenant database. You can even create it in Data Guard for Disaster Recovery. Now, Oracle is pushing ACFS to store the datafiles rather than direct ASM. Especially in multitenant because a great feature is thin cloning: CREATE PLUGGABLE DATABASE AS SNAPSHOT COPY. However, I encountered an error when…

Oracle Public Cloud 12cR2: TDE is not an option

By | Cloud, Database Administration & Monitoring | No Comments

In Oracle Public Cloud, Transparent Data Encryption is not an option. You can use it because it is included in all database services for all editions. You have to use it because the database won’t allow you to create, or import, non encrypted tablespaces. This is controlled by a new parameter, encrypt_new_tablespaces, which defaults to CLOUD_ONLY;

Exadata Express Cloud Service: MAX_PDB_STORAGE

By | Cloud, Database Administration & Monitoring | No Comments

The separation of roles between system DBA and application DBA is the way to go for agile development and the PDBaaS managed service is an excellent way to play with this concept: You are PDB administrator but not the CDB administrator. Here is an example about tablespace creation/deletion, and the kind of problems that may arise with this architecture.

Running SLOB on Exadata Express Cloud Service

By | Database Administration & Monitoring | One Comment

The Exadata Express Cloud Service is a managed PDBaaS: Oracle is the system admin and the CDB database administrator, you are the PDB administrator. You connect with a local user, PDB_ADMIN, which is no SYSDBA privilege but has a PDB_DBA which has nearly all DBA rights, but with some features disabled by lockdown profile. I have no worry about the performance on this service: it is an Exadata X5 half rack bare metal (my guess),…
