can you please advise?
Thanks.

Answer 1

Can you share the WSO2 SP version you were using when you got this exception?
Also please check whether the AUTO_SERVER=TRUE
config is avaiable in the jdbc url of WSO2_METRICS_DB datasource configuration, which can be found in
{WSO2_SP_HOME}/conf/worker/deployment.yaml
eg :
jdbcUrl: 'jdbc:h2:${sys:carbon.home}/wso2/dashboard/database/metrics;AUTO_SERVER=TRUE'

Answer 2

I configured all datasource in mysql, and i can running all SP componnent.
the issue is related to H2 datasase, that not allowed to share connection with default configuration.
i will check default H2 connection parametrs, and test again.
