Hard disk drive space management

Buffer Pool Analyzer needs to keep its input files (the buffer pool data files and trace data files) on the client's local hard disk drive to perform its functions. Further, Buffer Pool Analyzer keeps its results (from object placements, simulations, and long-term analyses) also on its local hard disk drive. Over time, you might have collected a multitude of input files and results that unnecessarily use up hard disk space.

Buffer Pool Analyzer does not perform any cleanup. All files and results remain on the hard disk until you delete them. Use the following guidelines to delete no longer required files and results:

Input files

Buffer pool data files (*.bpd) and trace data files (*.trace) are stored in optional folders, which are determined by you when these files are downloaded.

Delete these files by using the client's functions (Windows Explorer).

Output files

Results from different Buffer Pool Analyzer functions are stored in folder C:\Documents and Settings \<userid> \db2pev<version> \… \… and various subfolders. Do not delete individual files from these folders; they are also used by other DB2® Performance Expert functions and as temporary work area. If required, use them only to determine how much hard disk space they use (Windows' Properties function).

To delete results, use the Buffer Pool Analyzer main window. Refer to one or more of the following sections for a description:

This process ensures that all files belonging to a report or result are properly deleted.
