Hi,
I'm trying to connect from Oracle 11g (11.2.0.1.0) to Sybase Adaptive Server Anywhere (9.0.2.3527). My Oracle environment is running on Linux Centos 5.3, the sybase database runs on a Windows Server.

All my attempts have failed so far - both through Oracle Database Gateway for Sybase and via Oracle Database Gateway for ODBC in combination with freeTDS. Using either way I'm ending up with apparently the same error:

ASA Error -611: Transact-SQL feature not supported

When I use db link created via dg4sybs (Oracle Database Gateway for Sybase) I get this:
SQL> SELECT * FROM aaa@hvx;
SELECT * FROM aaa@hvx
*
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
OracleODBC Sybase Wire Protocol driverSybase ASEASA Error -611:

ORA-02063: preceding 2 lines from HVX

My agent init file {$ORACLE_HOME/dg4sybs/admin/initdg4sybs.ora} contains:
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Sybase

#
# HS init parameters

HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER

When I use db link created via dg4odbc (Oracle Database Gateway for ODBC) and freeTDS driver I get this:

SQL> SELECT * FROM aaa@hvx1;
SELECT * FROM aaa@hvx1
*
ERROR at line 1:
ORA-28511: lost RPC connection to heterogeneous remote agent using

ORA-02063: preceding line from HVX1
Process ID: 12664
Session ID: 49 Serial number: 21020

In the ODBC trace file I can see the same error:
...

My unixODBC & freeTDS configuration should be OK - I can sucessfully connect via isql:

It seems both drivers use Transact-SQL instructions which are then denied by ASA. I'm not familiar with Sybase products at all, but as far as what my googling revealed the Transact-SQL is only supported in Adaptive Server Enterprise (enterprise-class version of Sybase's database). I couldn't figure out if there's a way how to disable Transact-SQL in the driver configuration. Has anybody faced (solved) this problem? Is there a proved way how to connect from Oracle (10g or 11g) to Sybase Adaptive Server Anywhere?

Thanks a lot in advance.

hi zdenek,

were u able to find a solution for this issue. we are facing exactly the same issue with connection from oracle to sybase.

insert into ttable(select * from STAN_STG where rownum<100000)
this statement works fine and inserts all the rows, but when i try to get 1000000 records it errs out as shown below.

ERROR at line 1:
ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1551))(CONNECT_DAT
A=(SID=dg4sybs)))
ORA-02063: preceding line from TDB
ORA-06512: at line 9


can u tell me if you found any way to solve the issue.

thanks,
c

Hi,
my solution was simple - I moved to a MS Windows XP box where the connection from Oracle (both 10gXE and 11g) to Sybase ASA works like a charm. I'm using ODBC driver Adaptive Server Anywhere 9.0 in combination with Oracle Database Gateway for ODBC.
