Heterogeneous Connectivity :: Change When Moving System Using Gateway ODBC?
Jan 27, 2013
Oracle 11gR2
Linux 6.x
Sybase 12 (on Windows)
unixODBC 3.2.x
Sybase Client 12
------------------------
Given the following files or structures that are important to the proper operation of the ODBC Gateway connecting to a remote Sybase database:
listener.ora
tnsnames.ora
initmydblink.ora ( my version of the initdg4odbc.ini )
dblink (not a file but the dblink in the Oracle database)
odbc.ini
odbcinst.ini
What files (and what properties within those files) may/must be changed if the remote Sybase db and system is different (i.e. the Sybase database source has been changed to something 'new')? For example, I can that the odbc.ini file is going to have to be alterer to point to the new database server IP address, database port, database name?

we have microsoft sql server, oracle gateway server (11G) and database server (10.2.0.5) we already make the full setup, and it's working.
we create materialized view into oracle server to read a data from sql server, but the refresh of MV take long time so we are planing to create the materialized view into oracle gateway server.
create MV into oracle gateway server?i mean i don't want to download oracle database instance for only one MV.

We are planning on interfacing Oracle to SQL server connectivity, I'm researching on how to create a dblink to SQL server 2005. I'm a little confused between Generic connectivity and Transparent Gateways..
I think Transparent Gateway is not free and needs to be licensed, is it better in terms of performance? Also, do I need to configure this gateway on a seperate server?
I think Generic connectivity can be configured on the same Oracle database server itself.. but I see there could be some performance issues with it..
We are running on Oracle 10.2, looks like HSODBC is not available in 10g?

select from the postgre databse works just fine (however when i select data column alone it returns as date, if i select it together with som condition in where clause it returns varchar).
-- this runs ok
select
t."idbill",
t."idpoint"
from "crm"."bills2points"@dl_carecloud t
,"crm"."bills"@dl_carecloud brg
where 1=1
and t."idbill" = brg."idbill"
and t."idbill" = 9685;

What are the steps required to change an ORACLE stored procedure (on a AIX/UNIX machine) using OTG to connect to a DB2 database, to an ORACLE stored procedure that uses ODBC or JDBC connectivity?
All I need to do in the stored procedure is a simple insert statement into a DB2 table.
What kind of ODBC/JDBC driver do I need on the UNIX machine? unixODBC?
What would be different in the ORACLE stored procedure for it to use ODBC connectivity rather than OTG.

We have a requirement to connect from 9.2.0.8 database on AIX to MS SQL 2008R2 .
Source :
----------
Oracle : 9.2.0.8 (64 bit)
OS : AIX - 4.3.3.0/5.3.0.0 (64-bit)
Target :
----------
MS SQL : 2008R2
OS : Windows 2008 (64-bit)
1] Can we use - Database Gateway for SQL Server for the above set up ? If so , does this require a separate license ?
2] Where Do we need to install the "Database Gateway for SQL Server " -- soruce or target server ?
3] Is there any other solution apart from using "Database Gateway for SQL Server " ?

I am working on oracle and pl/sql since some time. so just a novice. I don't know much about sql server or transact sql, etc..I have a requirement to create an interface between Oracle and sql server.
we have a database on oracle and another on sql server. my requirement is to create an interface between oracle and sql server and see how can I update one (or more) tables (I am guessing using pl/sql) on sql server.

My setup is following:
CODEhost22 (Oracle Linux 5.9) | host30 (Windows XP) with SQL Server Express 2008
DB22 | Gateway to MSSQL | DB30
Local Local | |
Capture --> Apply ------> Gateway -----------------> DUMMYUSR.DUMMYTBL
Process Process | |
Capture process on DB22 captures changes made to local DUMMYUSR.DUMMYTBL table, enqueues it to capture queue and propagates to apply queue for local apply process, which, using database link DB30 supposed to apply these changes to table DUMMYUSR.DUMMYTBL on remote SQL Server database DB30.
The problem is that when apply process is executing transaction, it aborts with error:
QUOTE ORA-26713: remote object does not exists or is inaccessible.
ORA-26712: remote object is "DUMMYUSR"."DUMMYTBL"@"DB30".
In trace log I can see the following message:
QUOTE kniNoPrimaryKeyError: ORA-26713, remote obj doesn't exist,
DUMMYUSR.DUMMYTBL@DB30
[code]...
what can cause ORA-26713 error of apply process applying changes to SQL Server database through Oracle Database Gateway, if object to be modifyed exists and accessible from Oracle database for strmadmin user?
By the way, database link and tables were created with following commands: CODEDB22(Oracle): (connected as strmadmin) create database link DB30 connect to "dummyusr" identified by "dummypwd" using 'DB30';
DB22(Oracle): (connected as dummyusr)
create table DUMMYTBL (no number, name char(6), ddate date, payload varchar2(2013));
DB30(MSSQL): (connected as dummyusr)
create schema DUMMYUSR authorization dummyusr;
create table DUMMYUSR.DUMMYTBL (no float(53), name char(6), ddate datetime2(0), payload varchar(2013));

I want to connect ORACLE-11gR2 that is on linux with an MS sql server. DO i need to use some third party drivers like easy soft ? Can i configure the database gateway without any third party drivers ?
Secondly if my oracle is on linux, can i configure the gateway on a seperate windows machine(that will connect to linux oracle and ms sql server) as i have found the gateway installation setup only for windows version.

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:
[code]....
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
SID=ORA-28511: lost RPC connection to heterogeneous remote agent using
[code]....
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. how to connect from Oracle (10g or 11g) to Sybase Adaptive Server Anywhere?

I have trouble reading a field called "Description" from a SQL Server 2008 DB using the gateway:
SQL> select "Description"
from opportunity@mscrm
select "Description"
from opportunity@mscrm
*
Error at line 1
ORA-00904: "Description": ungültiger Bezeichner
My first thought was, that "Description" was a reserved word in Oracle but it's not:
SQL> create table delete_this ("Description" varchar2 (50 char))
Table created.
SQL> select "Description" from delete_this
no rows selected.
So everythings fine here. Then I thought, that I might have mispelled the column name, but no:
SQL> select column_name
from v_mscrm_tab_columns
where table_name = 'opportunity'
and column_name like 'Desc%'
[code]....

What are the pro's and con's to using the APEX Listener vs the Embedded PL/SQL gateway?
We just started using APEX and on a development server, we set it up using the EPG because this seemed like the easier thing to do. However, they now have a couple apps that are approaching production status and I now need to look at placing the APEX runtime on our production Oracle Database server. So I am trying to decide if I should continue using the EPG or if I should use the APEX Listener.
The server is Windows Server 2008 Enterprise R2 (64 Bit) with Oracle 11g R2 (11.2.0.3.0) also running at 64 bit. I am planning on using APEX 4.2.1.
I have also not found information about how to move APEX application from development to production. Do I export the schema from the dev server and import it to the production server? Do I have to recreate the same workspace name on the production server as well?
use a separate dev and production server setup for APEX?

I have following file setup for Oracle heterogeneous services for MS Access. I also need to add one more dsn for MS Excel.
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
#
# HS init parameters
#
HS_FDS_CONNECT_INFO = MyConn
HS_FDS_TRACE_LEVEL = 0
#
# Environment variables required for the non-Oracle system
#
#set <envvar>=<value>
Note: MyConn is for MS Access that I cretaed.
Can we use like this
HS_FDS_CONNECT_INFO = MyConn1, MyConn2,etc.
