We are running on ECC 6.0 system.
We have connected to three different external databases which are Oracle databases only.
We have created Z programs and we are running those programs in background which are connecting to these external databases. Some of the programs finishes successfuly while spome of them finishes with the ABAP dumps EXSQL_UNKNOWN_CONNECTION and DBIF_DSQL2_OBJ_UNKNOWN.
What could be the problem?
Is it the connectivity problem, as sometimes the job finishes and other times it terminates with the above mentioned ABAP dumps?
If yes, then how to test the connectivity with the external databases from SAP system.
Thanks & Regards,
