Hi,

Problem:
Database error text........: "ORA-02019: connection description for remote database not found?"

We have Database link between two database QA1 and ATSQ.

QA1
RDBMS Version: 7.3.3
OS: IBM/AIX RISC System/6000: Version 2.3.4.0.0

ATSQ:
RDBMS Version: 8.0.5
OS: IBM/AIX RISC System/6000: Version 2.3.4.0.0

We created database link between QA1 to ATSQ. and then we created Public synonym for some of the table for ATSQ.
When access table from SQL prompt It works fine.

SQL> CONN SAPR3/@QA1
Connected.

SQL> SELECT COUNT(*) FROM AT_TERM@QA1ATSQ;

COUNT(*)
---------
241

1 row selected.

SQL> SELECT COUNT(*) FROM AT_TERM;

COUNT(*)
---------
241

1 row selected.

Here AT_TERM is public synonym for AT_TERM@QA1ATSQ Link.
A problem is that when SAP program access this table it gives error "ORA-02019".

Also same program access data from ATSD thru DV1. (DV1 has link to ATSD.)
This link is working fine. but program unable to UPDATE data of ATSD.

Can anybody help...?
