Connection to h2 drops after 1/2 hour of inactivity
Hello everybody,
I have a problem with a h2 defined as JNDI resource in JBoss. When I run my application it connects perfectly to the h2. However if I do not use the app during approximately 1/2 hour then I am not able to connect the database again
I get the following error:
Caused by: java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/jdbc/ORA_BQWJB001

My resource is defined as follows:
<datasources>
<datasource jta="false" jndi-name="java:/jdbc/ORA_BQWJB001" pool-name="QWJB2" enabled="true" use-ccm="false">
<connection-url>jdbc:h2:mem:elara;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=RUNSCRIPT FROM 'D:/ENTORNO_LOCAL_APX/dirBaseEjecucion/qwjb/online/multipais/multicanal/sql/QWJB_DDL.sql'</connection-url>
<driver>h2</driver>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>20</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>admin</user-name>
<password>admin</password>
</security>
</datasource>
Does anybody the reason for that behaviour? Or is there a way to define a keep alive time in order not to shut down the connection after a time?
Thank you very much in advance!
