Problem

Integration Engine shows 'Stopped' in the B2Bi UI and the Integrator/data/trace/8 logs show the following lines looping:

INFO :20260329:03.08.53.94:r4edi(b2bx_server):clusterconfig.s4m:352:* Unified is waiting stop *

INFO :20260329:03.08.53.94:r4edi(b2bx_server):clusterconfig.s4m:352:* Unified is terminated *

The Integrator/data/log/unified.log shows the following error:

2026-03-30 11:32:05 [Thread-0 ] ERROR L140 UnifiedMain.lambda$execute$2 - Error for /export/axway/b2bi/Integrator/java/lib/jfiler-loader.jar in thread

Caused by: java.lang.RuntimeException: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

The Integrator/data/log/dblogger.log shows the following error:

2026-03-30 11:38:56 [-mainpool-4-thread-3] ERROR L157 StartupManager.lambda$startLogger$5 - Exception while initializing/running the dynamic instance 2; entire logger process will die

java.lang.RuntimeException: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

Resolution

Edit the Shared/local/config/runtime/runtimedb.properties file so that the db.url contains "serverTimezone\=<TIME_ZONE>" which should match the database timezone configuration.
