You plan to migrate an existing production database supporting online transaction processing (OLTP) workloads to the Exadata Database Machine. The database currently supports an application requiring fast response times, which satisfies stringent requirements, and most of the application queries use index access to the tables in the application schema.
For which case would you consider dropping indexes to allow Smart Scans to occur?
Identify the correct sequence of commands to completely power off a Database Machine in an Orderly fashion:
1. Execute ''crsctl stop cluster --all'' as the grid user from one database server.
2. Execute ''crsctl stop cluster --all'' as the root user from one database server.
3. Power off all network switches using their power switch.
4. Execute ''crsctl stop cluster --all'' as the root user from one database server.
5. Execute ''crsctl stop cluster --all'' as the grid user from one database server.
6. Power off the rack using the power switches on the PDUs.
7. Execute ''shutdown --h now'' on all database servers.
8. Execute ''shutdown --h now'' on all Exadata storage servers.
9. Execute ''shutdown --h now'' on all servers.
Which three must be true for Smart Scans to be done?
A table in one of your database schemas contains only varchar, number, and date data types for the columns.
Which three operations can be offloaded to the Exadata storage servers when doing a smart scan against this table, if no other situations arise that prevent Smart Scan from occurring?
You are checking the status of the ports on the one of the InfiniBand switches in your Database Machine.
You have run the getportstatus as shown:
You have 36 ports to check.
Which two methods would you use to check the status of all 36 ports?
