Community Insight
Tests knowledge of Oracle Clusterware behavior with PDBs, specifically distinguishing between local listener registration and global OCR registration, while highlighting limitations on automated startup.
Identifies the true statements regarding the default service created upon Pluggable Database (PDB) creation in an Oracle RAC environment. The page establishes that this service is not automatically registered in OCR and cannot be used by Clusterware to automate opening the PDB.
Candidates often incorrectly assume the default service is automatically registered in the Oracle Cluster Registry (OCR) or uniformly available across all instances without specific configuration.

Expert Analysis
Why the Answer Is Correct
The default service created for a PDB behaves differently than the database-level services in terms of automation and registry management. Statement B is correct because the default service does not have the necessary attributes set to allow Clusterware to automatically open the PDB; manual intervention or explicit configuration is required. Statement E is correct because the default service is not automatically registered in the Oracle Cluster Registry (OCR). While it registers with the local listeners on the instance where it is running, it does not appear as a managed resource in the OCR by default.Why the Other Options Are Wrong
Option A is incorrect because the availability of the service depends on the configuration (administered vs policy-managed) and whether the PDB is open on that specific instance. Option C is incorrect because, as noted, automatic registration in OCR does not happen for the default PDB service without specific commands likesrvctl modify service or enable. Option D is misleading; while policy-managed databases distribute resources, the key distinction tested here is the lack of OCR registration and automation capability, making E and B the definitive technical truths.Community Comment Notes
Community consensus strongly supports options B and E. Users note that for OCR registration, you typically need to runsrvctl commands explicitly, confirming that it is not automatic. One commenter verified the documentation stating that the default service lacks the automation capabilities for opening the PDB, reinforcing option B. Official Reference
Exam Strategy
Focus on the differences between how the default PDB service operates versus manually configured services. Remember that 'default' often implies 'minimal' functionality, meaning less automation and fewer automatic registrations in cluster components like OCR.
Frequently Asked Questions
Why is the default PDB service not registered in OCR?
It is not registered automatically; you must use srvctl to add or enable it in the OCR.
Can Clusterware open a PDB using its default service?
No, the default service lacks the configuration needed for Clusterware to automate the opening process.
