[jboss-user] [Performance Tuning] - What is the Maximum Connection Pool size if nothing is configured in the -ds.xml file?

jduran [https://community.jboss.org/people/jduran] created the discussion "What is the Maximum Connection Pool size if nothing is configured in the -ds.xml file?" To view the discussion, visit: https://community.jboss.org/message/792414#792414 -------------------------------------------------------------- Does anyone know what the default value is of the max pool size within the -ds.xml file?  As you can below we only have minimum set to 0 with no entry for maxium.  I'm worried the vendor who configured this was thinking no maximum entry means unlimited.  Im wondering if no entry takes the default value Jboss assigns. I'm not sure what that value is.  Reason i'm concerned is because I'm getting this error: Njavax.transaction.TransactionRolledbackException: Error obtaining connection: org.jboss.util.NestedSQLException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] )); My -ds.xml file     datasources>     <local-tx-datasource>     <jndi-name>SabaSite</jndi-name>     <connection-url>saba:jdbc:JSQLConnect://********/database=######/asciiStringParameters=false</connection-url>     <driver-class>com.saba.mssql.SabaJNETMSSQLDatabaseDriver</driver-class>     <min-pool-size>0</min-pool-size>     <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>     </local-tx-datasource>     </datasources> Thanks, Justin -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/792414#792414] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
