Time outs issue in Synchronous Interface

Hi Experts,

We have an SAP ECC to JDBC synchronous interface. We are using 7.1.

A jobs triggers Proxies from SAP which fetches data from JDBC and returns to SAP in a synchronous call.

The issue happens mostly after downtime's where in when the SAP jobs are triggered after the downtime we run into fetch huge amount of data and face time out issue resulting in failed messages.

What steps can be taken to prevent this?

What I want is how can we fetch huge amount of data in a single synchronous call without the interface failing.

What all timeout parameters should we work on?

Can setting XMBWS.Timeout in the receiver JDBC Channel solve the issue?

Thanks,
