Logs from batch job
As per the documentation on
https://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.html. We have implemented
Tomcat Connection pool in our project. It is a Java batch job and we are using
below properties.
maxTotal="100"
maxIdle="20"
removeAbandoned="true"
removeAbandonedTimeout="1800"
Our batch job abruptly ends with below logs:
exitDescription=org.springframework.transaction.TransactionSystemException:
Could not roll back JPA transaction; nested exception is
org.hibernate.TransactionException: Unable to rollback against JDBC
Connection\n\tat org.springframework.orm.jpa.JpaTransactionManager.doRollback
I need to understand what should be the combination of these params?
removeAbandoned as per documentation is for longest running query but this
fails even the queries run less than 5 mins.
Is there a different param like maxAge we need to use?
Also attcahed complete logs too.
Pls help as this is impacting our batch jobs.
Thanks
Angadpaul
