During provisioning of virtual pluggable databases (VPDB's), Delphix will establish an auxiliary container database in which it will perform recovery of the VPDB, the VPDB is then unplugged from this temporary container database and plugged into the the destination container database. By default this auxiliary container database will have its memory structures sized based around the size of the dSource container database. This size may cause issues for the target host if resources allocated in dSource environment far outweigh those in the target VDB host environment. Controlling the SGA sizing in the auxiliary container database is performed through what are known as repository templates. The repository template essentially override the default behaviour and are used to set the desired Oracle database parameters you would like to see used in the auxiliary database during the provisioning process.
The process to perform the provisioning of a VPDB using a repository template as a part of the process is the following:
1. Create a VDB configuration template using the Delphix GUI called aux_cdb_params with the following parameters set as a bare minimum.
compatible = 184.108.40.206 enable_pluggable_database = true sga_target = 1551892480
The parameters required may differ given a specfic environments requirements from this but this should allow the startup of the auxiliary database.
2. Create a repository template called aux_cdb_templ using the CLI
delphix repository template> create delphix repository template create *> set name=aux_cdb_templ delphix repository template create *> set container=PDB12C1 delphix repository template create *> set repository=OELC9/'/u01/app/oracle/12.1' delphix repository template create *> set template=aux_cdb_params delphix repository template create *> commit
delphix repository template 'pb12c1rt'> ls Properties type: SourceRepositoryTemplate name: aux_cdb_templ container: PDB12C1 reference: REPOSITORY_TEMPLATE_REF-4 repository: OELC9/'/u01/app/oracle/12.1' template: aux_cdb_params
name is what you want the template name to be.
container is the source VPDB.
repository is the target environment/ORACLE_HOME that the CDB target is running from.
template is the name of the database template created in the GUI.
3. Provision a virtual pluggable database (VPDB) via the Delphix GUI using the source PDB defined as the container in the repository template and provision the VPDB to the target environment defined by the repository (target environment/Oracle Home combination) in the repository template.
