40 PDB Upgrade using Fleet Maintenance
This chapter covers the PDB Upgrade using Fleet Maintenance feature. It contains the following sections:
Introduction
Fleet Maintenance provides solution for upgrading PDBs provisioned on Enterprise Manager DBaaS cloud. This solution implements an out of place upgrade of a PDB by relocating the target PDB to a Container Database at a higher version and other existing PDBs running in the container are not impacted.
Pre-requisites
-
Create a successor pluggable database pool containing CDBs at a higher version to which the target PDB will be relocated as part of upgrade. For example, if you want to upgrade PDB version 12.1.0.2 to 12.2.0.1, create a successor PDB pool with CDBs at DB version 12.2.0.1.
-
Create a successor service template which is configured to provision in the successor pool.
-
Oracle Application Express version on the source CDB hosting the target PDB and CDBs in the successor pool must be same.
-
PDB pool must have privileged credentials configured.
-
Update implication of request settings to the discovered instance.
Pre-Configuration for Upgrade
This section provides pre-configuration details for upgrade:
Configure a successor pool running following command:
$ emcli db_cloud_maintenance -performOperation -purpose="ATTACH_POOL" -pool_name="<Pluggable Database Pool name hosting the target PDB>" -pool_type="pdbaas_pool" -name="Attach successor pool" -description="Attach pool" -destPool="<EM Target name of the successor Pluggable Database Pool >" -destPoolType="pdbaas_pool"Configure a successor service template running following command:
$ emcli db_cloud_maintenance -performOperation -purpose="ATTACH_ST" -stName="<Name of the service template associated with PDB target to be upgraded>" -name="Attach successor ST" -description="Attach ST" -destST="<Name of the successor service template"Upgrading PDB
This section provides details on upgrading PDB using EMCLI command:
$ emcli db_cloud_maintenance -performOperation -purpose="UPGRADE_PDB" -pool_name="<Pluggable Database Pool name hosting the target PDB>" -pool_type="pdbaas_pool" -name="Upgrade PDB to new CDB" -target_type=oracle_pdb -description="Relocates the PDB" -target_list="<EM Target name of the PDB to be upgraded>" -input_file="data:<absolute path to input file> " –destCDB=<EM Target name of the destination CDB>Optional Parameter:
destCDB=<EM Target name of the target CDB to which PDB target is relocated as part of upgrade process.>Input file Parameters:
WORKLOADS=<Workload size name from the successor service template to be associated with upgraded PDB>
USE_SAME_STORAGE_LOCATION=Y #Optional parameter to be used only with –destCDB, when PDB is to be upgraded without moving the datafiles.
