Problem when loading data with Data integrator 12.2.0.0 to BW 7.0 - RFC

Hi Experts (Data integrator with SAP BW 7.0)

We are facing a problem when loading data from Data integrator to BW 7.0 as a target.

BW = 7.0 SP 14 and Data integrator = Data Services version 12.2.0.0

The dataflow is the following ... ORACLE > DI > BW 7.0

In BW side we have a process chain with 10 or more infopackages, in the other side (Data integrator) we have 10 or more jobs waiting for the Bw trigger. When starting the Process chain some infopackages works fine, but frequently the RFC connection in Data integrator fails and in BW side the error message is "Error when opening an RFC connection".

Sometimes only the first infopackage runs correctly and the others are cancelled.

In the Management console in DI we can verify that the RFC is locked. If we try to stop and restart the following message appears "Could not get JCo server: DI_SQW@UIPABI50:Server configuration for

DI_SQW@UIPABI50 is already used for a running server".".

Somebody knows if we can not run a process chains with several infopackages in sequence requesting data from a Data Integrator Server ? Is it a Constraint ?

Best Regards

Mauro.
