9.5.13. tpm purge-thl Command

The tpm option purge-thl is designed to assist with identifying the safe removal of THL based on the following rules:

  • Gather the last applied seqno from all Replica nodes and take the lowest one

  • Find the current THL file which contains that seqno, then locate the previous one

  • construct a thl purge command to remove thl thru the last seqno in the prev file

A replicator service name name may be optionally specified as the last argument, for example:

shell> tpm purge-thl -A alpha

The default behavior is to display the needed commands for the admin to execute manually.

The tungsten_purge_thl can be used as a read-only option to generate the commands required to purge manually.
