Transaction Manager Log Files

TIBCO recommend that you do not replicate the transaction data that is logged by Transaction Manager on each node.

Each BPM node (for example, BPMNode), and the System node (SystemNode), has an embedded Transaction Manager (TxM), which logs its transaction state to files in the following directories:

CONFIG_HOME/tibcohost/Admin-enterpriseName-adminServerName/nodes/nodeName/work/HowlLogs

CONFIG_HOME/tibcohost/Admin-enterpriseName-adminServerName/nodes/nodeName/work/GeronimoTMID

Although transaction state data is stored in the file system, it changes as rapidly as other operational data. Consequently, if the primary site fails, some in-progress transactions may be lost.

To ensure data consistency between the primary and DR sites, TIBCO recommend that you do not replicate the HowlLogs and TxM GeronimoTMID log directories to the DR site.

If you do replicate the HowlLogs and TxM GeronimoTMID log directories to the DR site, you must remove any files from the HowlLogs and TxM GeronimoTMID log directories on the DR site before starting TIBCO ActiveMatrix BPM. See Before Starting TIBCO ActiveMatrix BPM on the Secondary Site.
