	An 8-engine Adaptive Server is undergoing a high rate of Logical I/Os and spinlock contention in the default data cache. The DBA has used Sybase ASE Monitor and has found that two 4MB tables are table-scanning within the application. This is causing 50% of the server's Logical I/Os. The code within the application cannot be changed. The task for the DBA is to increase throughput of the Adaptive Server and lower the amount of spinlock contention without changing indexes, tables or the application. Which two are valid operations which should be done to meet this objective? (Choose 2.) A. Create two named caches of 2 MB each and then recycle the Adaptive Server to activate them. B. Create two named caches of 5 MB each and then recycle the Adaptive Server to activate them. C. Create two 5MB 16KB Page Pools within the default data cache. Bind the two small tables to these page pools. D. Bind the two tables to their own newly-created and active named cache. E. Compress the tables which join to the two small tables so that they are chosen as outer tables. This will eliminate the need to table scan the small tables.	View Answer
