Unformatted text preview: Benjamin, p. 273-275 Chapter 5: Language Enhancements Oracle 9i New Features, Robert Freeman, p. 141 Chapter 5: Miscellaneous Oracle9i Features and Enhancements QUESTION 97: Which two are true regarding a list-partitioned table? (Choose two.) A. It is possible to partition an index-organized table using the LIST method. B. It is NOT possible to have multiple columns as the partition key of a listpartitioned table. C. The keyword NULL can be specified as a partition literal value for one partition of a list-partitioned table. D. The keyword MAXVALUE can be specified as a partition literal value for one partition of a list-partitioned table. Answer: B, C Explanation: It is NOT possible to have multiple columns as the partition key of a list-partitioned table. It's possible to specify the keyword NULL as a partition literal value for one partition of a list-partitioned table: the set of values that specifies a partition cannot be empty; it must contain at least one value. Incorrect Answers A: List partitioning is supported for heap tables only. IOTs do not support this feature. D: You cannot specify MAXVALUE. You can specify a NULL value.

A. Define a new buffer pool by setting the DB_nK_CACHE_SIZE parameter where n is the new block size. B. Redefine the buffer pool by setting the DB_mK_CACHE_SIZE and DB_nK_CACHE_SIZE parameters, where m is the standard block size and n is the new block size. C. Rebuild the control file using an instance with an initialization file containing two DB_BLOCK_SIZE parameters, one for the standard and one for the new block size. D. Rebuild the control file using an instance with an initialization file containing two DB_nK_CACHE_SIZE parameters, one for the standard and one for the new block size. Answer: A Explanation: Before adding a nonstandard block size to your database you must define a new buffer pool by setting the DB_nK_CACHE_SIZE parameter where n is the new block size. To create tablespaces with multiple block sizes, you must first configure database buffer caches corresponding to the required block sizes. To support this feature, Oracle9i has introduced new initialization parameters. DB_CACHE_SIZE specifies the database buffer cached to the standard block size. Oracle9i 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 B: You cannot redefine the buffer pool by by setting the DB_mK_CACHE_SIZE an...
