mlogchk

The mlogchk command performs consistency checks on the persistency directory installationDirectory/pw/server/varcellName. This directory could be in an inconsistent state after abnormal cell or StateBuilder termination. It is an interactive tool that tells the operator what is wrong and what must be corrected.

You must shut down the cell before running the checks because a running cell might modify the log directory during a check.

The mlogchk command does the following:

  • Determines whether an mcdb.lock file exists and, if so
    • Checks for a running statbld and waits for termination 
    • Reports the trailing lock file and removes it (after confirmation) 
  • Determines whether an xact.1 file exists and, if so, reports and instructs the user to run statbld 
  • Determines whether an mcdb.0 file exists and, if so, reports and proposes to rename or remove it
