ctquiet options to support incremental backup restore points

The ctquiet utility will put the FairCom Server into a quiet state using the c-tree ISAM ctQUIET() function.

Several changes have been made to ctquiet to support restore points necessary to carry out an incremental backup strategy:

  • The -r feature can be used to generate the restore point files necessary to carry out an incremental backup strategy.
  • The ctQTfailAfterTimeout mode has been extended to apply to restore point checkpoint creation for incremental forward rolls.
  • The -x option applies the ctQTfailAfterTimeout mode to the already existing options.
  • The -t timeout output has an effect only if -f or -r is specified.
  • The default timeout has been changed to match the server's maximum.

The new syntax is:

ctquiet [-s server][-f][-r][-u][-x][-t timeout][-w command] {-p password|-a authfile}

  • -s - Server (default: FAIRCOMS@localhost).
  • -f - Full consistency (default: crash consistency).
  • -r - Create an incremental backup restore point. Automatically unquiets server.
  • -u - Unquiet server.
  • -x - Abandon Quiet request if timeout exceeded. (Default: abort long transactions).
  • -x - Apply ctQTfailAfterTimeout mode. This mode has been extended to apply to restore point checkpoint creation for incremental forward rolls.
  • -t - Seconds to wait before aborting transactions (the default timeout matches the server's maximum). This option has an effect only if -f or -r is specified.
  • -w - Execute command on successful quiet. Waits for SIGINT to unquiet server.
  • -a - Authentication file name.
  • -p - Admin Password.
