We’ve already discussed how to migrate databases from a standalone 12.2 database to a pluggable database (PDB) in a 19c container in the Oracle cloud. But what if the target container database (CDB) is already part of a Data Guard configuration and has several PDB in it? I will try to go through the main steps on how to do that without breaking the replication.Continue reading “Migrating a new PDB to the existing 19c DataGuard on ExaCC.”
Today I would like to discuss the block storage allocation in a VM based Oracle DBCS system. Several times in different conversations it was mentioned that the block storage will be allocated with triple redundancy on the ASM level. Let’s check it out.
Oracle Database as a service (DBCS) on Oracle Cloud Infrastructure (OCI) had been traditionally built based on Oracle Grid Infrastructure with ASM as the main storage layer for the database, however Oracle recently has started to offer a Linux LVM as the storage alternative. Which option is the better alternative? Let’s review some of the differences between the two options.
