DRAFT KB-XXXX How to tell how many transactions are left to replay


Appian engines will replay transactions in an event of an unexpected shutdown. In an event of such occurrence, the engine startup time will depend on how many transactions the engines have to replay, such that a higher number of replays can delay the engine start up time.

This article outlines how to find out how many transactions are left to replay and how much time will it take for the Appian engines to boot up.


Navigate to <APPIAN_HOME>\logs\service_manager.log and search for log entries of the following type which have details on the engine name, number of transactions to replay and the approximate time this will take:

[KomodoEventBus-50] INFO  com.appian.komodo.engine.status.ReplayStateProvider - download-stats 15 of 142 transactions replayed (10%). Approximately 00:57 remaining.

Affected Versions

This article applies to Appian 17.3 and later.
