Hello Experts,
we tried to connect a Firebird Database form a third party as source via Data Services. After some time of trying, the connection over JDBC is working fine. We are able to take a look on tables and views from the source system. The only problem is, that it is not possible to get data. There is no possibiltiy the use the data preview on source objects (not on the ojects as such or as result over a query). The following failure apperar:
(14.2) 10-12-15 10:31:19 (E) (18112:19576) RUN-058107: |Data flow __DF_DS_JIT_VIEWDATA_|Reader REP_ISOLATION__JITSampling
- Fehler beim Lesen von <REP_ISOLATION__JITSampling>: <Cannot connect to JDBC driver.>.
(14.2) 10-12-15 10:31:30 (E) (13452:5428) RUN-058107: |Data flow __DF_DS_JIT_VIEWDATA_|Reader REP_ISOLATION__JITSampling
- Fehler beim Lesen von <REP_ISOLATION__JITSampling>: <Cannot connect to JDBC driver.>.
If I load it into a taget structure, there will be nothing inside, comprehensibly.
It is not totally clear to me, why I can access but not read data. We had suspected permissions in the source system. The strange thing is that, for example, I can retrieve data by using DB Visualized over JDBC. We do not quite understand what is happend here in the background of Data Services. The driver seems to work, because we can access the structure and DB Visualizer is working fine by using the same driver (there it works completely inkl. Data perview). Apparently there is maybe a called function in Data Services that the driver is not able to provide?
Is there anybody who has experience on connecting third party systems via JDBC on Data Services (particular Firebird DB)? Or someone who can tell me something about the error?
