The tungsten_post_process command was added in versions 5.4.0 and 6.0.5
The tungsten_post_process assists with the graceful maintenance of the static cross-site replicator configuration files on disk.
The tungsten_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:
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:
Below is an example INI file showing section identifiers only:
[defaults] [defaults.replicator] [east] [east.replicator] [west] [east_from_west] [west_from_east]
Of the above example section identifiers, only the following would be used by tungsten_post_process:
The remaining example section identifiers (
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.
Filter out any files that are not static replicator configurations.
The tungsten_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.

Below is a sample session:
tungsten_post_processAbout to update the following config file(s): /opt/continuent/tungsten/tungsten-replicator/conf/static-east_from_north.properties /opt/continuent/tungsten/tungsten-replicator/conf/static-east_from_west.properties Do you wish to continue? [y/N]
yDone! 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
From release 6.1.6 onwards, the tungsten_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
