Allows you to display the in-memory contents of a row cache for
    an open database.

1  –  Description

    The RMU Dump Row_Cache command is intended for use as a
    diagnostic aid that allows you to display the in-memory contents
    of a row cache for an open database. Use this command to display
    the following information for each row in the specified cache:

    o  GRIC - Address of the GRIC data structure for the cache slot

    o  GRIB - Address of the GRIB data structure for the cache slot

    o  SLOT - Slot number within the cache

    o  NXTGRIC - Slot number of the next slot within the hash chain

    o  LHMTE - Flag values indicating:

       -  L - Row is latched

       -  H - Row is marked Hot (modified since last checkpoint or
          sweep)

       -  M - Row is marked Modified

       -  T - Row is marked Too Big for (or removed from) the cache

       -  E - End of on-disk checkpoint file; should never be seen
          with the RMU Dump Row_Cache command

    o  SNAPPNO - Snapshot pointer (either snapshot page number or
       snapshot slot number

    o  LEN - Length of the row in cache; 0 indicates row has been
       deleted

    o  ACTLEN - Actual length of allocated space on the database page
       for the row

    o  DBK - Database key for the row

    o  REFCNT - Reference count: number of processes with this row in
       a cache working set

    o  UPD_PID - Process ID of process currently updating the row in
       memory

    o  RVNO - In-memory row modification count

    o  TSN - Transaction sequence number of last transaction to
       modify the row
