Introduction Cloning PDBs in Multitenant environments is an easy way to migrate a PDB from one CDB to another or to create multiple copies of that PDB for test and development purposes. The data files are being read from the source and transferred to the target CDB. Hence, cloning a PDB also means generating workload…
Introduction Oracle Multitenant enables you to migrate and consolidate multiple databases as PDBs into one CDB. However, these databases might be of different character sets. Starting with Oracle Database release 12.2.0.1, PDBs within the same CDB can be of different character sets, provided the CDB is created with the AL32UTF8 character set. By the way,…
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 straight forward 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 we discussed how creating the master encryption key on the primary 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 first. The Environment I’m using Oracle Database Cloud service Enterprise Edition Extreme Performance. The database version is 19.8. TDE…
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 For EE-HP and EE-EP, you can create up to 4096 PDBs. For SE and…
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…
