DB2 connection problem in WebSphere

DB2 connection problem in WebSphere

I am getting below issue while server startup.

DSConfigHelpe W   DSRA8200W: DataSource Configuration: DSRA8020E: Warning: The property 'connectionAttribute' does not exist on the DataSource class com.ibm.db2.jcc.DB2ConnectionPoolDataSource.

com.ibm.commerce.wc.appmanagement.exception.WCAppManagementException: com.ibm.websphere.ce.cm.StaleConnectionException: [jcc][t4][10380][11951][4.19.66] Required property "mydbhost.com" is unknown host. ERRORCODE=-4222, SQLSTATE=08001 DSRA0010E: SQL State = 08001, Error Code = -4,222

Solution : Please check hostname used in resources.xml and wc-server.xml files are correct. 

WCDE_V9\workspace\WC\META-INF\ibmconfig\cells\defaultCell\applications\defaultApp\deployments\defaultApp\resources.xml

<resourceProperties description="The name of the server, used with thin driver setup" name="serverName" required="false" type="java.lang.String" value="mydbhost.com" xmi:id="J2EEResourceProperty_1123801797694"/>

After updating value, Please restart server.
