DSNB546I PREFERRED FRAME SIZE preferred-size buffer-count BUFFERS USING frame-size FRAME SIZE ALLOCATED
Explanation
This message is a section of output from the DISPLAY BUFFERPOOL command, which is part of message DSNB401I.
DSNB546I: Frame size allocation
Message DSNB546I describes the frame size allocation status of the buffer pool. If the specified number of buffers with the specified frame size are not available, Db2 allocates some of the buffers with a different frame size. In that case, Db2 issues multiple instances of this message to show the number of buffers that are allocated with each frame size.
DSNB546I - PREFERRED FRAME SIZE preferred-size buffer-count BUFFERS USING frame-size FRAME SIZE ALLOCATED - preferred-size
- The requested frame size. If you used the ALTER BUFFERPOOL command with the FRAMESIZE option, the specified FRAMESIZE value is displayed as preferred-size.
This value can be 4K, 1M, or 2 GB.
- buffer-count
- The number of buffers that are allocated with the frame-size value.
This value might include storage frames that have been logically removed from the buffer pool, but which Db2 cannot yet free.
- frame-size
- The actual frame size that Db2 used for the buffers.
This value can be 4K, 1M, or 2 GB.
