Configuring Services on Oracle RAC and Oracle RAC One Node Databases

You must add services to the PDBs after installation, if you add PDBs after installation.

If you do not add services to pluggable databases (PDBs), and then the Oracle RAC One Node multitenant container database (CDB) fails over to another node, or you manually relocate the CDB to another node, then by default, all PDBs associated with the CDB that do not have registered services are restarted in MOUNTED state.

PDBs are opened in Read-Write mode after failover, in case of Oracle RAC One Node database, or relocation in case of any Oracle RAC database, only after you have configured the PDBs to have associated services. If you have not associated services to PDBs, then the PDBs remains in MOUNTED state when the CDB instance restarts.

Use the following srvctl command syntax to add services to a PDB, where cdbname is the name of the CDB, service_name is the name of the service, and pdbname is the name of the PDB:
```
srvctl add service -d cdbname -s service_name -pdb pdbname
```
After you add services to your PDBs, if you relocate the CDB with which the PDBs are associated, or the CDB fails over for Oracle RAC One Node databases, then the PDBs associated with that CDB automatically open in Read-Write state.
