The FILEMAPPED_MEMORY_DIR statement specifies the directory that stores temporary file-mapped memory files for PowerExchange Listener statistics on AIX PPC64, i5/OS (IBM i), and Solaris SP64 systems. If you set the STATS statement to MONITOR in the DBMOVER configuration file, the memory statistics are generated when either the optional monitoring interval in the MONITOR parameter elapses or when you issue the DISPLAYSTATS or pwxcmd displaystats command.
Informatica strongly recommends that you use this statement to specify a directory that is dedicated to the storage of temporary file-mapped memory files for PowerExchange Listener statistics. Specify a directory that is on a locally mounted disk for better performance and to avoid complications that result from network mountings, such as name clashes, disk usage problems, and the unnecessary inclusion of NFS files.
AIX, i5/OS (IBM i), and Solaris
By default, temporary file-mapped memory statistics files are written to the current directory of the user, or if the current directory is not available, to the top-most root directory of the file system.
  • Monitor the directory that the FILEMAPPED_MEMORY_DIR statement specifies. On AIX or Solaris, you can use the
    command to delete the files that are not being used by an active PowerExchange process.
  • If you cancel a Listener task by using an operating system command such as
    kill -9
    , the memory files are orphaned.
