RE: OPS questions

    I had done some research on the various of HA options. From the reviews and experiences of other companies who have implemented OPS. 1. The OPS architecture is implemented on the expensive Hardware Cluster that has to be purchased from the HW vendor. A cost factor involved here. 2. OPS is a specialized skill that need the expertise of a Senior DBA both with the OPS experience to install, implement and support the architecture. 3. OPS has load-sharing properties so that is a definite advantage. 4. OPS software is an add-on and SW has to be purchased separately so another cost consideration.

     Evaluating all pros and cons we decided to go for the Veritas HA solution for Oracle. If you interested I can elaborate on the comparative analysis.
Hope that helps.

I am looking for some truthful information on OPS (Oracle Parallel Server).

Some questions I have are:

• Are people really using this as a failover solution?
• Is this a better solution than a standby database?
• How are tnsnames.ora (at the client level) entries resolved if one server goes down?
• Does OPS have any load balancing features?
• It appears that OPS is good if a server crashed due to a bad CPU, etc - but the database is still a single point of failure. If an object runs out of space, or the archive directory fills up, OPS does not buy you anything.
• Is it difficult to maintain multiple SGAs on all the servers?

Anyone have any experiences to share?  

Thanks....
