Create dblink in Oracle/Linux (RHEL4) to MS SQL Server/Windows?

Hi,
Can anyone share me the procedure to Create dblink in Oracle/Linux (RHEL4) to MS SQL Server/Windows?
Thanks

Hi,
to access non-Oracle systems you must use Oracle Heterogeneous Services.
You have to follow the instructions from Heterogeneous Connectivity Administrator's Guide to perform it.

Oracle 9i on LINUX Transparent Gateway for SQL Server

Does anybody know if there is a Transparent Gateway available for Oracle 9i on LINUX to connect to SQL Server? I have run the installer and cannot seem to find the install options for any Transparent Gateways. I am familiar with their location in the universal installer as I have installed the Oracle/SQL Server Transparent Gateway with Oracle in WinNT. Perhaps Transparent Gateways for Oracle/LINUX are not available?
Thanks in advance.

I have the same issue - we want to upgrade our 9.2 to 10g Linux, and need to maintain connectivity to some legacy sqlserver databases. I can't find any mention of tg4msql for linux. What gives? Anyone know the answer to this? thanks, michael

Oracle Transparent Gateway for MS SQL Server

Hello,
I successfully installed the Oracle transparent Gateway for MS SQL Server for Oracle 8i. Now I am doing the same for Oracle 9i.
Does anyone know how to 'create a new gateway service' on 9i???
This is how you would do that on 8i on the Windows box...
1) At the MS-DOS prompt, enter:
> set GTW_EXE=TG4MSQL.EXE
2) To create a new gateway service name, enter:
> GTWSRV73 sid -CREATE | MORE
-where sid is the gateway sid.
Does anyone know how to do those steps for 9i Oracle Transparent Gateway?
Thank you.

Hi

The distribution agent failed to create temporary files in 'C:\Program Files\Microsoft SQL Server\110\COM' directory. System returned errorcode 5.

One of my replication job failed with below error, which means job failed because of permission issue on the folder. To resolve that, I have granted the permission and it started working fine. Now the question is as my job was running fine since long time
without any issue then how suddenly the permission of the folder got omitted automatically? I am sure that no one deleted the permission from the folder and as the server is part of SQL cluster no failover occurs.
Error:-The distribution agent failed to create temporary files in 'C:\Program Files\Microsoft SQL Server\110\COM' directory. System returned errorcode 5.
Rahul

Hi Rahul,
Error code 5 indicates that the error is "access is denied." Please make sure that the COM folder is excluded from any antivirus scan that occurs on the system.
If the issue still persists, I recommend you use
Process Monitor to find out a bit more about the accounts and access requests involved. Then grant write permission to the exact COM folder for the account that is running the SQL Server Agent service. For more details, please review the following similar
thread.

What are the advantage of using Oracle Database when compare to SQL SERVER

Hi all
Please tell anyone about

Hi,
There are various differences between the two.
1. SQL Server is only Windows, but Oracle runs on almost all Platforms.
2. You can have multiple databases in SQL Server, but Oracle provides you only one database per instance.Given that the very term 'database' has s different meaning in the two products, this "difference" is absolutely meaningless.
3. SQL Server provides T-SQL for writing programs, whereas Oracle provides PL/SQLWhich means what? Both products have a procedural programming language. They named them differently, and the languages are not interchangeable. Means nothing in comparing the features/strengths/weaknesses/suitability to purpose.
4. Backup types in both are the same. (Except Oracle provides an additional backup called Logical Backup.)You make that sound like "Logical Backup" is something more than it is. It is nothing more than an export of the data and metadata. Many experts don't even consider it a backup. I'm sure SQL Server provides the same functionality though they probably call it by some other name.
5. Both provide High Availability.Well, I guess they both have a suite of features they refer to as "High Availability". But what does that really mean? The devil is in the details. Remember, the two products don't even agree on what constitutes a "database".
6. Both come in various distributions.???

If you are going for an Implementation, you can try SQL Server Express Edition and Oracle XE which are free to use.
Then you can choose whichever is comfortable for your needs.

Specifying Partner Failover in odbc.ini for Linux ODBC driver for SQL Server

Hi,
We are trying to specify the partner failover when making connections via Linux ODBC driver for SQL Server. Do you know a way to specify partner failover in the DSN entry in odbc.ini?
We are using Linux ODBC driver for SQL Server and unixODBC DriverManager.
Our DSN is:
[MyDSN]
Driver=ODBC Driver 11 for SQL Server
Description=MyDSN
Server=MySERVER,<port>
I also tried to use the following connection string in Python (via pyodbc) bypassing the DSN and connecting using the server name.
cnxn = pyodbc.connect("Server=server1,<port>;UID=sa;PWD=<pwd>;Driver=ODBC Driver 11 for SQL Server;Failover_Partner=Server2,<port2>;Database=MyDB")
If the standby DB is on server1 connection fails. It doesn't try server2. If the DB is principal on server1 connection succeeds.
Thank you,
Liviu
LLL

Hello,
Did you use ODBC Driver for SQL Server to connect to database that uses database mirroring?
According to
the BOL,it does not list "Failover_Partner" as ODBC Driver for Linux connection string keywords.
But ODBC driver for Linux supports
AlwaysOn Availability Groups or Failover Cluster Instance by specify MultiSubnetFailover=True when connecting to a SQL Server 2012 availability group listener or SQL Server 2012 Failover Cluster Instance.
The following case is about similar issue and it seems that ODBC Driver on Linux does not recognize Failover_Partner in connection string. (Not test myself).You can refer to:

Is Oracle still actively creating AMIs for Oracle Linux?

Hi All,
I was wondering if any of you knows if Oracle is still actively creating new Oracle Linux AMIs for Amazon EC2? I can see the most recent one is Oracle Linux 6.1 while we are already at 6.3.
Now that Oracle has announced they are in the IaaS and PaaS business as well, do they stop supplying Amazon AMIs?
Bart.

I would never deploy the first point release of a major release into production. In my experience, Oracle rolls out 2 "releases" of each major version. The SECOND release tends to be production-ready for shops with serious HA requirements. Usually, this Second release also contains sneak previews of the important features of the next major Version--but these should be considered version 1.0 features and not relied upon. The FIRST release of a major version will contain those important features in a strong form suitable for the vast majority of shops--but it will still have lots of bugs. If you have to bounce your instance even once a month to work around a bug, you aren't getting close to HA.
My advice--the most stable version will always be the terminal release of the last version--currently 9.2.0.6. Similarly, the last point release of R1 will be quite stable. Realistically, 98% of the customer base can live with occasional downtime and bug problems, and will enjoy the new features of the latest software. Even for them, I'd wait for the second point release or higher for production. QA and DEV are different stories--jump on the latest wave and write code using the newest features. But wait for the second point release before going into production. Typically it will be out in a few months and will fix the glaring bugs.

Using Oracle Heterogenous services to access sql server database table

I have created a dblink 'POC_HS' from oracle to sql (implemented heterogeneous services) and I am able to successfully pull out data from the default database that the DSN(for sql server) is connected to.
So this 'select * from Test@POC_HS' is working perfectly fine on the Oracle database as 'Test' table resides in the default database (which the System DSN is connected to).
But when I do 'select * Abc.Test@POC_HS' where Test table resides in 'ABC' database which is not the default database throws an error as follows:
ORA-00942: table or view does not exist [Generic Connectivity Using ODBC][Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'Abc.Test'.[Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared. (SQL State: S0002; SQL Code: 208)
I have also tried this 'select * from Abc.dbo.Test@POC_HS' but oracle throws this exception "ORA-00933: SQL command not properly ended".
The dblink user and System DSN account has access to the 'Abc' database.
Thoughts?

Thanks for the info.
But suppose if we have DB link 'POC_HS' where POC_HS is a DBlink between oracle servers, I can do the following -
1. select * Abc.Test@POC_HS
2. select * Def.Test@POC_HS
where Abc,Def are the schemas which the Dblink user has access to. I can execute the above perfectly fine.
I wanted the achieve the same functionality from Oracle to Sql where database keep on changing dynamically . So according to you that's not possible right?
We will have to keep on changing the ODBC connection to a different database or create a new odbc/listener/tnsentry each time query uses a different database right?

Oracle AS connect to MS SQL server - help please.

hi there
can anyone tell or show me how to connect Oracle app server to MS sql server? thanks

Hi Tom,
For stand-alone OC4J (any version), you need to add an appropriate entry to the "data-sources.xml" file (in the "j2ee/home/config" subdirectory) and put the JDBC driver file(s) into the "j2ee/home/lib" subdirectory. On my OC4J 9.0.3 distribution (on my Windows XP machine), there already is a "ms-sql.xml" file in the "j2ee/home/config/database-schemas" subdirectory. If you don't have one, then you may need to create one, or if you do already have one, you may need to modify it. More information can be found at these Web sites:
http://www.orionserver.com
http://www.orionsupport.com
http://www.atlassian.com

Hope this helps you.
Good Luck,
Avi.

Oracle forms and reports in SQL Server

My company has developed a application in Oracle forms and reports that works with a Oracle database. In the database also exist a lot of triggers, procedures, functions and packages.
The application is working perfectly with the Oracle database but I have a request from a very promissing potencial client that has the restriction that could only use a SQL Servr database.
I know that we have to create a new version of the all database objects, including triggers, function, procedures but my main question is if is possible and if works a forms/reports application connected to a SQL Server database?
Thank you for your help

MichaelFerrante,Thank you for your help.
I have already used the HS services to connecto to external databases from our main Oracle database, and the solution works fine.
But unfortunally for this particular client he cannont have installed a Oracle database due to internal policies restrictions.
I can not migrate the full application to another technology like ADF in less than 6 or 8 months.
Do you thifnk that there is any other solution?
