[Quoted] Hi All,
Have few questions related to Oracle RAC, Please provide your inputs on these :
- Based on what condition load balancing is happening between 3 Nodes?
- Suppose 10 queries are executed from the application to the Database, how the load balancing happens in this scenario :
- The first 3 queries will go to Node1, the next 3 queries will go to Node2 and next 3 queries goes to Node3; and the last query goes to Node1 again? [Quoted]
- The first 4 queries will go to Node1, the next 3 queries will go to Node2 and next 3 queries goes to Node3 ?
- Any limit that can be set to a node on the No.Of queries executed, like 20 queries can be executed in Node1 and 30 queries on Node2 ? [Quoted]
- Any other comments related to this scenario ?
- I have 2 databases (Database1 and Database2) and i need to configure to configure the 3 Node RAC as below :
- Node1 to take INSERT and DELETE statements alone from Database1,
- Node2 to take SELECT and UPDATE statements alone from Database1, and
- Node3 to take all operations from Database2
- Is this possible, If yes how/where to configure these ? ii) How to identify that this scenario is working properly. Is there anything, other than AWR Reports to check this? iii) RAC configuration files are placed in which server of this 3 Node RAC scenario ? iv) For Database1, data is stores in 3 places, Node1 server local storage, Node2 server local storage and Shared Storage (where Node1 and Node2 data syncs up). If yes, When does the data sync happens ? [Quoted] v) Any other comments ?
Thanks in Advance,
Raja
