10.5.15. tpm post-process Command

The tpm post-process Command assists with the graceful maintenance of the static cross-site replicator configuration files on disk.

The tpm post-process command performs the following steps:

  • Locates, reads and parses the various INI configuration files.

    Below is the list of possible INI files and file match patterns:

    • {$HOME}/tungsten.ini

    • /etc/tungsten/tungsten*.ini


      Please note that all files in the /etc/tungsten directory starting with tungsten and ending in .ini will be used.

    • /etc/tungsten.ini

  • Identifies cross-site services that are local to the node, as well as the main local service.


    Only Replicator options and properties for specific entry types are currently supported.

    The supported stanzas are as follows:

    • {service}.replicator
    • {service}_from_{service}

    Below is an example INI file showing section identifiers only:


    Of the above example section identifiers, only the following would be used by tungsten_post_process:

    • east.replicator
    • east_from_west
    • west_from_east

    The remaining example section identifiers (defaults, defaults.replicator, east and west) would be ignored.

  • Gathers configuration options and properties defined for each identified local service.

  • Locates the associated configuration file on disk and gets the existing value for the option key.

  • Interactively prompts for confirmation. This may be bypassed using the -y option to tpm post-process.

  • Filter out any files that are not static replicator configurations.

  • The tpm post-process command will then do one edit-in-place per ini option per local service.

  • The script will check to make sure the value has been updated.

  • Finally, there will be a summary message and helpful instructions about next steps. This may be bypassed using the -q option to tpm post-process.

Below is a sample session:

shell> tpm post-process
About to update the following config file(s):


Do you wish to continue? [y/N] y


tungsten_post_process updated 0 configuration options successfully and skipped 6

Pick one node and set Maintenance mode so the manager does not try to bring the replicator online when you don't want it to: 

  echo "set policy maintenance" | cctrl

Then take the Replicator offline gracefully on one node:

  trepctl -all-services offline

Restart the Replicator:

  replicator restart

Bring all services online:

  trepctl -all-services online

Check the status:

  trepctl services

Repeat as needed.

When all nodes are done, pick one node and execute:

  echo "set policy automatic" | cctrl


The post-process will be automatically called by tpm during update and install to ensure any cross-site specific configuration is applied at the correct time
