Hello,

I’m trying to use the Natural Native Interface to call a NATURAL subprogram.  
In this subprogramm everything works fine, when there is no access to the database.

When a do a FIND or anything else in this subprogram I get the following message:

```auto
...Done. Return code = 3148.
MessageNumber: 3148.
MessageText: NAT3148 Database 1 is not active or not accessible
Library: TGAP50.
Member: LON-PLDA.
Name: .
Method: .
Line: 2560.
```

I think the Database number 1 is wrong, but how can I tell the NNI the right Database number?  
The subprogram works if I call it from a NATURAL program

Thanks  
D.E.

What does your call to nni\_initialize look like? Do you initialize the Natural session in the NNI program with the same parameters as the Natural session where the database access works? Please check. Regards, +o:-]

😃 That’s it, Natural had to know the database-number with udb=NNN and now it works.

Thanks
