By Franck Pachot . In the previous blog posts I explained how to create, and stop/start the Autonomous Data Warehouse Cloud service. And I didn’t show yet how to connect to it. It is easy, from sqlplus or SQL Developer, or SQLcl. But there’s something more exciting to run some SQL queries: the Oracle Machine Learning Notebooks based on Apache…
By Franck Pachot . In the previous post, I explained how to create an Autonomous Data Warehouse with PSM (PaaS Service Manager Command Line Interface). The most common operation you want to do with it is starting and stopping the service. This is the best way to save credits for hourly billed services. And PSM is the easiest: run from…
By Franck Pachot . 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.

For the last conference day, after the Keynote about “JavaScript: The next Language YOU should learn” by Dan McGhan , I decided to attend presentations on following topics: – Upgrade your APEX app with zero downtime by using EBR – Understand and make use of CSS(3) – Best Practices for APEX Administrators – APEX Version Control and Team Working –…
By Franck Pachot . 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…
By Franck Pachot . Oracle Database licensing can be based on two metrics: Processor or Named User Plus (NUP). NUP also necessitate to count the processors because there is a minimum number of NUP per processor. Then it is very important to know how to count processors. The time where a machine had 1 socket with 1 processor with 1…
By Franck Pachot . I usually explain that the main point about Multitenant Architecture is the separation of roles between a system DBA who manages the container, and is responsible for its availability, and application DBA who owns all the application objects, and is responsible for data integrity and performance. The Exadata Express Cloud Service is the implementation of that:…
By Franck Pachot . Oracle Transparent Data Encryption is available without option on the Oracle Public Cloud: Standard Edition as well as Enterprise Edition (EE, EE-HP EE-EP, ECS). More than that, the DBaaS enforces TDE for any user tablespace even when not specifying in the CREATE TABLESPACE. It you are not familiar with TDE key management (wallets) then you have…
By Franck Pachot . You love the Oracle Public Cloud with its simple Web interface? Great. But what if you want to automate a database creation from command line? Easy with the CURL and REST API.

Everything is documented: https://apicatalog.oraclecloud.com/ui/views/apicollection/oracle-public/database/1.1/serviceinstances $ cat createrequestbody.json …
Azure offers two deployment models for cloud components: Resource Manager (RM) and Classic deployment model. Newer and more easier to manage, Microsoft recommends to use the Resource Manager. Even if these two models can exist at the same time in Azure, they are different and managed differently: in PowerShell cmdlets are specific to RM. In order to be able to…
By Franck Pachot . This morning I wanted to test a patch (18633374) in the Oracle Cloud Service. The DBaaS was created as an ‘Enterprise Edition Extreme Performance’ which comes with all options, including multitenant option. I applied my patch. My test required to create a new tablespace but it failed with: ORA-65010: maximum number of pluggable databases created This…
By Franck Pachot . When you create a DBaaS on the Oracle Cloud services you have to provide an administration password in the database configuration form. You do not need a password to connect to the VM. You use SSH key for it: on creation you provide the public key that will allow you to connect as the oracle user…
