Unformatted text preview: 73: The enterprise data warehouse routinely receives data from various production OLTP databases. The database block size on the data warehouse is 8192, and in the OLTP databases it may be 2048, 4096 or 8192. The current SGA is 112 MB. Oracle9i has the ability to transport tablespaces with different block sizes. Which two parameters are required in order to "plug in" the OLTP tablespaces into the warehouse database? (Choose two.) A. DB_2K_CACHE_SIZE B. DB_4K_CACHE_SIZE C. DB_8K_CACHE_SIZE D. DB_2K_BLOCK_BUFFERS E. DB_4K_BLOCK_BUFFERS F. DB_8K_BLOCK_BUFFERS Answer: A, B Actualtests.com - The Power of Knowing 1Z0-030 Explanation: DB_2K_CACHE_SIZE and DB_4K_CACHE_SIZE parameters are required in order to "plug in" the OLTP tablespaces into the warehouse database. DB_CACHE_SIZE specifies the database buffer cache sized to the standard block size. Oracle 9i can also support four additional block sizes; you can specify the buffer cache size corresponding to each of these block sizes with the DB_nK_CACHE_SIZE parameter. It this parameter, nK stands for the nonstandard block size; n can take the following values: 2, 4, 8, 16, or 32. Incorrect Answers C: The database block size on the data warehouse is 8192, so DB_8K_CACHE_SIZE does not need to be specified. D: There is no DB_2K_BLOCK_BUFFERS parameter in Oracle. You can specify the buffer cache size with the DB_nK_CACHE_SIZE parameter. E: There is no DB_4K_BLOCK_BUFFERS parameter in Oracle. You can specify the buffer cache size with the DB_nK_CACHE_SIZE parameter. F: There is no DB_8K_BLOCK_BUFFERS parameter in Oracle. You can specify the buffer cache size with the DB_nK_CACHE_SIZE parameter.

A. Create the user account and unlock the account. B. Create the user account and define a password. C. Unlock the user account and define a password. D. Set the 07_DICTIONARY_ACCESSIBILITY parameter to TRUE. Answer: D Explanation: To access a user account in the sample schemas you need to set the 07_DICTIONARY_ACCESSIBILITY parameter to TRUE. This enables anyone who had the ANY privilege to use this privilege on the Data Dictionary. Incorrect Answers A: You don't need to create the user account and unlock the account. B: You don't need to create the user account and define a password. C: You don't need to unlock the user account and define a password.
