Introduction In the Oracle Cloud, every newly created database from 12c onward uses the Oracle Multitenant Architecture. Transparent Data Encryption is also enabled by default. So, as soon as you use Data Guard and create new PDBs, you have to take care of copying the wallets to the standby server. We already discussed two approaches…
Introduction Creating and cloning PDBs in a multitenant environment is a simple and straightforward task, also when TDE is enabled. However, in a Data Guard environment where primary and standby use their own TDE wallets, it becomes challenging. In a previous blog post, we discussed how creating the master encryption key on the primary PDB…
Introduction A customer is having long upgrade times on-premises. As they are moving to the Cloud, I got the question whether their upgrade in the Cloud would be faster. First of all, when it comes to patching, upgrade, and migration, I can only encourage you to read the blogs by Mike Dietrich and Daniel Overby…
Introduction Oracle Multitenant architecture makes it possible to effortlessly move PDBs from one CDB to another, even though the source and target CDBs were of different release versions, e.g. 18c and 19c, and even of different editions like moving from SE to EE. In the previous blog we discussed how patching can be done with…
Introduction Oracle Multitenant allows you to clone PDBs from one CDB to another easily, even though the source and target CDBs were of different patch levels, e.g. 19.9 and 19.10, and even different editions like moving from SE to EE. The only thing you’ll need is to run datapatch afterwards. Unplug and Plug the PDB…
Introduction See what happens and how to proceed after creating or cloning a PDB in a Data Guard environment while Transparent Data Encryption (TDE) is enabled. If you are new to TDE, have a look at this blog post first. The Environment I’m using Oracle Database Cloud service Enterprise Edition Extreme Performance. The database version is 19.8.…
Introduction In this blog post we are going to have a step by step instruction to Enable Transparent Data Encryption (TDE). Create an encrypted tablespace. Create an auto-login wallet/keystore. Create a Secure External Password Store (SEPS). Clone PDBs from local and remote CDBs and create their master encryption keys. I’ll try to keep it as…
No, not necessarily. All Oracle databases from version 12.1 in the Oracle Cloud are automatically deployed using the Multitenant architecture. This is probably the reason why this question is asked. Let’s have a deeper look. Database Cloud Service (DBCS) License Included Oracle provides four pre-defined software editions in the Oracle Cloud to choose from. Each…
In this part we will introduce the following migration methods using Multitenant Architecture: Unplug & Plug Remote Cloning Remote Hot Cloning PDB Refreshable Clone PDB Relocate Multitenant Architecture The multitenant architecture provides easy and powerful features to move databases across platforms, even with just one single SQL command. It’s almost magic! The multitenant option was…
Oracle Database Standard Edition in the Cloud offers additional features including: All versions: Transparent Data Encryption, which is available only for Enterprise Edition on-prem. 18c onwards: Refreshable PDB Switchover, which is available only for EE on Engineered Systems (Exadata and ODA) on-prem. Additionally, in the Cloud you benefit from Automatic Backups, one-click Restore, one-click CPU up/down Scaling, and Simplified Patching. This…
