Troubleshooting¶
Notification; Unexpected error message¶
If you receive a notification message about an unexpected error message,
check the Failover Manager log
file for an
OutOfMemory message. Failover Manager runs with the default memory
value set by this property:
# Extra information that will be passed to the JVM when starting the agent.
jvm.options=-Xmx128m
If you’re running with less than 128 megabytes allocated, increase the value and restart the Failover Manager agent.
Confirming the OpenJDK version¶
Failover Manager is tested with OpenJDK. We strongly recommend using OpenJDK. You can use the following command to check the type of your Java installation:
# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
