IBM DB2 10.1 Advanced DBA for Linux UNIX and Windows Set 3

1.

In which situation would you NOT use a redirected restore?

To redefine the paths of a defined storage group. To move table space containers onto different physical devices. To restore a backup image from one operating system to another. To restore a backup image to a target machine that is different from the source machine.

2.

After starting a series of LOAD operations it appears that one LOAD is failing. What diagnostic tool would you use to determine which LOAD operation is being problematic?

db2pd db2dart db2fodc db2ls

3.

If the AUDIT_BUF_SZ configuration parameter is set to zero (0), what will happen?

The audit facility writes records to disk at the same time the statements generating the audit records are executing. Statements generating audit records must wait for the records to be written to disk before they cancomplete execution. The writing of audit records to disk will be delayed until a minimum number of records (based on recordsize and memory available in the database heap) have been generated. There is no limit to how many audit records can be stored in an internal memory buffer for one singlestatement generating audit records.

4.

Which constraints are used to tell the DB2 Optimizer to consider business rules that are not enforced by the database manager?

Check constraints Default constraints Informational constraints Referential integrity constraints

5.

Which procedure is used to Explain an SQL statement using information obtained from the package cache or the package cache event monitor?

EXPLAIN_FROM_DATA

EXPLAIN_FROM_ACTIVITY

EXPLAIN_FROM_SECTION

EXPLAIN_FROM_CATALOG

6.

Which statement about the initiation of parallel I/O is correct?

For list prefetching, each list of data pages is divided into smaller lists according to extent boundaries and assigned to different I/O servers. For read-ahead prefetching, each list of data pages is divided into smaller lists according to extentboundaries and assigned to different I/O servers. For sequential prefetching, parallel I/O is initiated when the prefetch size is a multiple of the extent sizefor a table space. Each prefetch request is divided into smaller requests and assigned to different I/O

servers. For sequential prefetching, parallel I/O is initiated when the extent size is a multiple of the prefetch sizefor a table space. Each prefetch request is divided into smaller requests and assigned to different I/O

servers.

7.

What will occur when a database administrator adds a new automatic storage path to an existing storage group?

New table spaces will start consuming storage on the new path. Existing table spaces will not consume storage on the new path. The storage group will be placed in "Rebalance Pending" mode. DB2 will verify that space is available on the storage path specified.

8.

Which monitoring tool can be used to obtain stripe set information for database managed storage table spaces?

The MON_GET_CONTAINER table function.

The SNAP_GET_TBSP_PART table function.

The SNAPTBSP_RANGE administrative view.

The TS_GET_CONTAINER administrative view.

9.

Which statement about value compression is correct?

To use value compression, you must have a license for the DB2 Storage Optimization Feature. Value compression uses a page-level dictionary based compression algorithm to compress data basedon repetition of values found in a single column. Value compression involves removing duplicate entries for a value, only storing one copy, and keepingtrack of the location of any references to the stored copy. When value compression is used, the byte count of compressed NULLs, zeros, and blanks might belarger than that of the uncompressed version of the same values.

10.

What advantage do block-based buffer pools offer compared to regular buffer pools?

They improve the performance of sequential prefetching by reading contiguous pages from disk and writing them into contiguous pages in a buffer pool. They improve the performance of random I/O by reading non-contiguous pages from disk and writingthem into near-contiguous free space in a buffer pool. They improve the performance of vectored reads by retrieving non-contiguous pages from disk,combining them into extent-sized blocks, and writing the blocks into contiguous pages in a buffer pool. They improve the performance of scattered writes by retrieving non-contiguous pages from a bufferpool, combining them into extent-sized blocks, and writing the blocks into contiguous pages on disk.
