• Question 25:

  Which of the following is true regarding disk offload?

  A. The amount of disk space to use cannot be specified.
  B. On server startup, DynaCache loads the entire disk cache into memory.
  C. The number of cache entries that are offloaded to disk cannot be specified.
  D. Disk offload can be enabled to have a cache entry copied to the file system at a configurable location.
  A. The amount of disk space to use cannot be specified.
  C. The number of cache entries that are offloaded to disk cannot be specified.
  D. Disk offload can be enabled to have a cache entry copied to the file system at a configurable location.

  ---

  AC: Before you enable disk offload, consider the following:

  You cannot specify the number of cache entries that are offloaded to disk.

  You cannot specify the amount of disk space to use.

  D: You can enable disk offload to have a cache entry copied to the file system (the location is configurable).

  High Performance Extensible Logging (HPEL) is a log and trace facility that is provided as a part of WebSphere?Application Server. HPEL provides a log data repository, a trace data repository, and a text log file. The HPEL LogViewer is an easy-to-use, command-line tool provided for HPEL users to work with the log data and trace data repositories. Use the following command to view the full contents of your log and trace repositories: [Windows] (Windows) logViewer.bat [AIX HP-UX Solaris] (Unix- full profile) logViewer.sh [AIX HP-UX Solaris] (Unix- Liberty profile) logViewer

• Question 30:

  An administrator has deployed an application that uses 30 unique SQL statements with a maximum data source connection pool size of 10. What is the recommended prepared statement cache size for the application?

  A. 10
  B. 30
  C. 40
  D. 300
  B. 30

  ---

  To determine the highest value for your cache size to avoid any cache discards, add the number of uniquely prepared statements and callable statements, as determined by the SQL string, concurrency, and the scroll type, for each application that uses this data source on a particular server. This value is the maximum number of possible statements that can be cached on a given connection over the life of the server. Setting the cache size to this value means that you never have cache discards. In general, configure a larger cache for applications with a greater number of statements.
