IO exception: The Network Adapter could not establish the connection

Hello All,

I am facing some problem with one JDBC receiver communication channel.

Here is the error which i am getting,

"Message processing failed. Cause:

com.sap.aii.af.ra.ms.api.RecoverableException: Error when attempting to

get processing resources:

com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to

create new pooled resource: DriverManagerException: Cannot establish

connection to URL 'jdbc:oracle:thin:@147.1.248.42:1526:AIMQ':

SQLException: Io exception: The Network Adapter could not establish the

connectio"

Can anyone please help me in this regard,

Thanks.
