Hi Ruchit I was just checking some other log files, actually the APP server is trying to call the DB server name with the hostname, but we have not included the IP's in DNS, so we need to change the hostname to IP address. See the below error in system.log file:
#1.5^H# #1221844546278#/System/Database/sql/jdbc##com.sap.sql.jdbc.NativeConnectionFactory#######Thread[main,5,main]##0#0#Error#1#com.sap.sql.jdbc.NativeConnectionFactory#Java#com.sap.sql_0002#com.sap.sql.log.OpenSQLResourceBundle#SQL error occurred on connection : code={0,number,integer}, state="", message="".#5#17002#<null>#Io exception: The Network Adapter could not establish the connection#jdbc:oracle:thin:@omtr-sap-ddbp:1527:DBP#<null>#
Is there anything that we need to change the jdbc:oracle:thin string ?
Thanks
