Is Transparent Gateway (4.1.1.1) supported in Oracle 8i

Hi We are having some RDB databases running in conjunction with Oracle 8.0.6.0.0 databases. We have installed Oracle 8.1.7.0.0 recently, and I am wondering if this 8i version is supporting Oracle Transparent Gateway ???
I ran an export in the existing DB 8.0.6, and I get this error during the import to 8.1.7.0.0:
Export file created by EXPORT:V08.00.06 via direct path
import done in US7ASCII character set and US7ASCII NCHAR character set
. importing OPS$2PC61's objects into OPS$2PC61
IMP-00017: following statement failed with ORACLE error 4052:

ORA-00604: error occurred at recursive SQL level 1
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from ICICMSR
This "GTW_SQL" is a object resides on serverside of the gateway and not in the databases (8i or RDB).
I am lost at this point. Any help would be of great use, and appreciated.

Linking to SQL Server using Transparent Gateways

I want to use the Transparent Gateways to link to a SQL Server DB.
I downloaded Oracle Enterprise Server from OTN.
As far as I can tell, the Transparent Gateways are supposed to be bundled with Oracle Enterprise Server, but I can't find them from the Universal Installer.
Does anyone know how I install the Gateways? Are they included with the downloaded Oracle Enterprise Server? If not, do I need to get the Oracle Enterprise Server CD Pack?
Thanks
Mike

You did create a DUAL table in the Sqlserver database?

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
I need oracle Tranparent Gateway for Microsoft Sqlserver (tg4msql) for oracle 10g on linux x86-64 bit. I have searched for it on otn.oracle.com and on edelivery.oracle.com. But couldn't find it.
Can any one help me in this regard.

Are the Oracle Transparent Gateways SAP approved

Gentlemen: Thanks in advance for your reply. I am new on this gateway world and I am trying to find the best solution for us.
Situation ... DB Migration of SAP 4.5B from MSSQL to Oracle8 in Sun Solaris (No problem with this).
We run a VB application that connects to SAP using SAPComm to read from SAP and update, asl well.
Problem: We will do the migration but the developer of the application in VB may not be open to change their coding, and we found the option of replicating db tables from Oracle to MSSQL, once we migrate, with the Oracle Gateway, which produce something transparent to the VB application.
Questions:
1. Does SAP approve this kind of accesses/replications to their DBs without us affecting our license agreement with them? I should ask this question to SAP, but if you know already, that will defenitely help?
2. I understand this tool (Oracle Transparent Gateway) is available as of Oracle9i. Our migrated SAP system will be running on Oracle8, but it is my understanding it does not matter the version of Oracle we are running our db, because what we procure is the Oracle9i to be installed separately to interact with both SAP (Oracle8) and MSSQL. Is that right? Could I build that scenario? If yes, how much is for the Oracle9i license. Should acquire it through SAP (I guess not)?
Thanks,
Juan-Carlos

You can use Oracle Streams to replicate from Oracle to SQL Server. This is a feature of Oracle 9.2.
This feature uses the Oracle Transparent Gateway for SQL Server to communicate between Oracle and SQL Server.
This is licensed separately from the database. Oracle 8 can communicate with Oracle 9i using DB links.
You can purchase a license for the each of these products at http://oraclestore.oracle.com/

Migration from 9i to 11g Transparent Gateway results in a) ORA-12704: character set mismatch b) ORA-02070: database ... does not support SYS_OP_C2C in this context

Migration from 9i to 11g Transparent Gateway results in a) ORA-12704: character set mismatch b) ORA-02070: database ... does not support SYS_OP_C2C in this context
What Transparent Gateway (TG) 11g configuration steps prevent the following errors?:
a) ORA-12704: character set mismatch
b) ORA-02070: database <DB_link_name> does not support SYS_OP_C2C in this context
Hints:
The current 9i TG works with the existing views and packages. These same db objects will not compile using the new 11g TG.
The db objects are on an Oracle 10g database linked to an SQL Server 2008 R2 database.
Since the 9i TG works I assume a configuration to the 11g TG will get it working same as before. But what...
Is is something controlled by these parameters? (Sorry, I don't know how this stuff works. I'm the application developer. My DBAs setup the Transparent Gateways.):
Parameters in the Gateway Startup Shell script:
    ORA_NLS33
    NLS_LANG
Parameters in the initsid.ora file:
    HS_LANGUAGE
    HS_NLS_DATE_FORMAT
    HS_NLS_DATE_LANGUAGE
I'm avoiding the known workaround to refactor the VIEWS and PACKAGES to contain CAST() statements to explicitly match the data types. A server side fix to the 11g TG is preferred.
Sample code:
a) ORA-12704: character set mismatch
   ... is caused by SQL that works with my 9i TG but not with my 11g TG. It's a snippit from my view that won't compile:
                  select status_code                  -- Oracle VARCHAR2(30)
                  from   ora_app_interfaces
                 UNION
                  select "StatusCode" as status_code -- SQL Server NVARCHAR(30)
                  from   SqlAppInterfaces
   Example workaround that I'm avoiding:
                  select status_code
                  from   ora_app_interfaces
                 UNION
                  select CAST("StatusCode" as VARCHAR(30)) as status_code
                  from   SqlAppInterfaces
b) ORA-02070: database <DB_link_name> does not support SYS_OP_C2C in this context
   A line of code in the procedure that compiles correctly but fails to execute:
           -- Insert into SQL Server from Oracle
           insert into PatientMedRecNum (
              "PatID",         -- SQL Server INT
              "MedRecNum",     -- SQL Server NVARCHAR(11)
              "Hospital")      -- SQL Server NVARCHAR(30)
           values (
              pi_pat_id,       -- Oracle NUMBER
              pi_med_rec_num, -- Oracle VARCHAR2
              pi_hospital);    -- Oracle VARCHAR2
I'd guess the errors are caused by the TG's implicit conversion between the Oracle VARCHAR2 and the SQL Server NVARCHAR... but this works fine on the 9i TG... how do I set it up to work on the 11g TG?
Thanks!

Trace of 11g TG... generating errors due to lack of automatic mapping from SQL NVARCHAR to Oracle NVARCHAR, where the previous 9g TG mapped from SQL NVARCHAR to Oracle VARCHAR2.

Is transparent gateway needed to connect to IS Cache database?

Hello,
I have been asked by one of our developers how to create a connection from his Oracle 11.2 database to SQL Server and also InterSystems Cache' databases without having to use Transparent Gateway?
Is this possible, and if so, how can it be done?
(thanks in advance)

Hi,
You say - "I guess it means that Oracle Database Gateway is FREE (per se)" but to make the point again - only the Database Gateway for ODBC (DG4ODBC) is free. The other gateways need a license.
If you run on Windows then many of the Microsoft ODBC drivers are free or included as part of other products so you do not need to pay for them, and also many non-Oracle database providers include an ODCB driver as part of the product, so again you do not need to pay for anything else to use DG4ODBC, for example MySQL.
To interface with a Cache database you can use Dg4ODBC but you need to provide the ODBC driver. There is not a 'dedicated' database gateway for that product. That is why we provide the DG4ODBC which can interface with any non-Oracle database or datastore for which a compatible ODBC driver is available.
This note available on My Oracle Support has information about the install notes on various platforms -

Transparent gateway to Sybase: connection error

I have been trying with little success to set up a transparent gateway to a sybase server.
The gateway is an NT 4 workstation, with an oracle server 8.1.7 installed. The sybase server is an ASE 12.0 on a Solaris 8 box.
Are these versions of the products supported? In the gateway documentation only Sybase 11 is mentioned...
Moreover all the examples/schemas given refer to an installation of the gateway on the same machine as the sybase server, whereas in my case the gateway is installed on a separate machine (but it is also stated that this configuration is allowed, provided a sybase client is installed togheter with the gateway).
From what I can make of the error messages / trace files, the problem lies in the gateway not finding the sybase server. But from the sybase client installed on the gateway machine I can connect to the same remote sybase server without hassles, so the sybase client is configured correctly.
Thanks for help,
Gaetano Giunta

Gaetano,
The supported products that we list in the manual is only what we have tested at print time. However we update our certification matrix regularly.
Please refer to the certification matrix on Technet.com ( http://otn.oracle.com/products/gateways/pdf/certmatrix2.pdf) for the latest certified configurations.
It looks like you have installed the gateway in the same Oracle home as the database. With v8.1.6 of the gateway this is not possible. With v9.x onwards this is possible.
You can either reinstall the gateway in another Oracle home or upgrade to v9.x.
I recommend that you upgrade to v9.x, since v8.x will be desupported shortly.
As of v9.x the Sybase gateway is located on the database CD and you can install it by doing a custom install.

Accessing SQL Server from ORACLE using Transparent Gateway

So I had downloaded the gateway installer and was following the guide here to set up the Transparent Gateway for SQL Server: http://www.orafusion.com/art_orahs.htm
After I had created the database link, I was prompted the following error when trying to do a simple select statement from the SQL Server DB:
>
ORA-12154: TNS:could not resolve service name
12154. 00000 - "TNS:could not resolve the connect identifier specified"
*Cause:    A connection to a database or other service was requested using
a connect identifier, and the connect identifier specified could not
be resolved into a connect descriptor using one of the naming methods
configured. For example, if the type of connect identifier used was a
net service name then the net service name could not be found in a
naming method repository, or the repository could not be
located or reached.
*Action:
- If you are using local naming (TNSNAMES.ORA file):
- Make sure that "TNSNAMES" is listed as one of the values of the
NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
(SQLNET.ORA)
- Verify that a TNSNAMES.ORA file exists and is in the proper
directory and is accessible.
- Check that the net service name used as the connect identifier
exists in the TNSNAMES.ORA file.
- Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
file. Look for unmatched parentheses or stray characters. Errors
in a TNSNAMES.ORA file may make it unusable.
- If you are using directory naming:
- Verify that "LDAP" is listed as one of the values of the
NAMES.DIRETORY_PATH parameter in the Oracle Net profile
(SQLNET.ORA).
- Verify that the LDAP directory server is up and that it is
accessible.
- Verify that the net service name or database name used as the
connect identifier is configured in the directory.
- Verify that the default context being used is correct by
specifying a fully qualified net service name or a full LDAP DN
as the connect identifier
- If you are using easy connect naming:
- Verify that "EZCONNECT" is listed as one of the values of the
NAMES.DIRETORY_PATH parameter in the Oracle Net profile
(SQLNET.ORA).
- Make sure the host, port and service name specified
are correct.
- Try enclosing the connect identifier in quote marks.

Can anyone assist me? thanks!

Hi kgronau,
>
After changing a listener.ora file you need to STOP and START the listener to get the changes loaded. It looks like your listener is not serving the 1524 port which could be related to the fact that you didn't stop/start the listener after you've edited the listener.ora file.
... But as stated earlier - please do not use a 10.2 listener to start an 11g gateway. Instead configure the listener of the gateway home.
>
I did restart my listener under services.msc whenever I make the changes but there are no effect. Please also note that I can only find "OracleOraDb10g_home1TNSListener" under my services.msc. There is no 11.2 Listener. I did install the gateway and the installation was successful as far as I can tell. But perhaps because there's no 11.2 Listerner under my services.msc, could that mean it was a bad installation?
>
Next point is the tnsping you've used is 11.2. You need to make sure that you use the tnsping of the Oracle Database home as the database initiates the gateway connection so the database home tnsnames,ora needs the tns entry for the gateway.
>
My current PATH environment variables setting is as follow: C:\oracle\product\11.2.0\tg_1\bin;C:\oracle\product\10.2.0\db_1\bin; So perhaps, I just need to ensure the 10.2 ORACE home is the first?
>
As a final tip: There are so many web sites explaining how to configure DG4ODBC - many of them are faulty. If you need a reliable configuration, please have a look at "My Oracle Support" => How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install     [Document 466225.1]     )

Can I join two tables from two different dbs by using transparent gateway?

E.g.:
select * from t1@rdb1, t1@rdb2
Can this work?

As previously stated you options depend on your Oracle version and platform and the target version and platform for the remote non-Oracle (well in this case mySQL) database.
Oracle replaced HS or Generic Connectiivy with a new name and support module on 11g and maybe in 10g. You can see your manual CD or check the online documentation.
For that matter you need to check to see if the Transparent Gateway product has a mySQL driver.
The following Oracle support articles may be of interest.

BLOB datatypes in Transparent Gateways

Hi,
Is the BLOB datatype supported in Transparent Gateway data conversions between Oracle 10g R2 and SQL Server?
I couldn't find any information on this in the Documentation on OTN.
Thanks, Ila

Hy,
you never could view blobs via sqlplus
you only could use utl_raw.cast_to_varchar2 if there ist text inside your blobs.

Any benefits of Oracle Transparent Gateway to connect to MSSQLServer ?

What are the benefits of Oracle 10G's Oracle Transparent Gateway to connect to MSSQL Server ?

Please be aware all gateways including the free component hsodbc up to release 10.2 have been desupported by 15th of Marcg 2008 and customers should use the follow up products.
The follow up product of TG4MSQL is Database gateway for MS SQl Server v11 and the follow up product of HSODBC is Database gateway for ODBC V11. The V11 gateway are certified with older Oracle database - but you might apply a gateway compatibility patch to the Oracle database release.
There are a lot of differences between DG4MSQL (TG4MSQL) and DG4ODBC (HSODBC):
- DG4MSQL supports many more functions it can directly map to SQl Server equivalents - DG4ODBC only suppors a few functions it can directly map to the equivalenst of a foreign database and all other functions are post processed. Post processing means ALL records from the remote table are fetched into the Oracle database and the result is then processed locally. Depending on the amount of data in the foreign table it might take a while
- DG4MSQL can call remote stored procedures
- DG4MSQL can participate in distributed transactions. This for example allows you to pass data changes in an Oracle table directly in the same transaction to the SQL Server side using triggers. Or you can also use STREAMS to replicate data between both databases.

Hi Felix,
Please take a look at note 234517.1 on metalink (copied below).
This note explains how to resolve the following error messages when using Transparent Gateways or Generic Connectivity:
ORA-3113; ORA-2019; ORA-2085; ORA-12154; ORA-28545; ORA-28546; ORA-28509; ORA-942; ORA-904; ORA-28500;ORA-28528
SCOPE & APPLICATION
This note should help to solve common error messages when using generic
connectivity or gateways.
Common errors with gateways or generic connectivity
Here are the English descriptions of each error; to compare your message
with the message below, you can alter your current SQL*Plus session
and compare your message with the messages listed in this note:
alter session set nls_language=american;
ORA-3113:
SQL> connect system/manager@tg4msql;
ERROR:
ORA-03113: end-of-file on communication channel
Resolution:
You can't connect with SQL*Plus directly to the foreign
data store. HS or Gateways are only designed to work with
a database link from an Oracle database to the foreign
data store

Resolution:
This problem is related to GLOBAL NAMES.
The simplest way to disable global naming is to alter
the current session.
alter session set global_names=false;
The other solution is to add a global_name to the
gateway/hs:
HS_DB_NAME = <datasource>
HS_DB_DOMAIN = <DOMAIN>
But the HS_DB_NAME must not exceed 8 characters and
must not contain any extra characters. If this is not
possible, the globale naming can be disabled by setting
GLOBAL_NAMES = FALSE in the init.ora of the database
as well
ORA-12154:
SQL> select * from all_catalog@demo;
select * from all_catalog@demo
ERROR at line 1:
ORA-12154: TNS:could not resolve service name
Resolution:
The database link uses a SQL*Net alias not specified
in the TNSNAMES.ORA of the database server.
Query the data dictionary to figure out the 'HOST'
specified for the database link:
select db_link, host from user_db_links;
or
select db_link, host from dba_db_links;
The 'HOST' value is the alias of the SQL*Net.
Please make sure it exists in the TNSNAMES.ORA file
present at the Oracle database server.
ORA-28545:

ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
NCRO: Failed to make RSLV connection
ORA-02063: preceding 2 lines from DEMO
Resolution:
There's something wrong with the SQL*Net connection:
- checking the SQL*Net -> Listener configuration with TNSPING:
tnsping <SQL*Net alias>
TNS-12545: Connect failed because target host or object
does not exist
The HOSTNAME specified in the TNSNAMES.ORA is invalid
Try with the OS ping to resolve the hostname / IP adddress
TNS-12541: TNS:no listener
The hostname specified in the listener.ora points to a
machine without an Oracle listener, the listener on that
machine is not running or the port number is wrong.
NO ERROR with TNSPING:
This might be caused by an invalid SID configuration.
Please make sure, that the SID in the listener refelects the
SID specified in the TNSNAMES.ORA. Make sure you don't mix
SID syntax with SERVICE_NAME syntax.
If everything is configured well, please make sure that
lsnrctl status shows at least one service handler for
hsodbc. Probably restart the listener AFTER changing
the listener.ora file.
Still no error found, then please enable listener tracing
(level support) and have a look at the listener.trace file
after retrying the same select statement again.
In the file you should see the connect from the Oracle
database to the listener. After a few lines you should see that
the listener tries to open 2 pipes. Does this work or does it
fail and again a few lines later you see a hex/ascii block that
conatins an error stack like:
ERR=12500, CODE=12500, EMFI=4, CODE=12560, EMFI=4?
Then please check again the listener.ora file; is the
ORACLE_HOME directory specified within the listener.ora file
correct? Or if you are using environment variables in the
listener.ora please replace them with absolute paths.
ORA-28546

Resolution:
This error might be caused by a misplaced 'HS=' or 'HS=OK' key
word in the tnsnames.ora.
Make sure HS= or HS=OK is present and that the SID Connect String
looks like:

Resolution:
This behaviour can be found in situations with a version missmatch.
For example the Oracle database is release 9.2.0.4 and the gateway
itself 9.2.0.1
=> The fix is to apply the same database patchset (gateway patches
are part of the database patchsets) to the gateway home as well;
or if the gateway 9.2.0.1 was installed into a 9.2.0.4 database
directory to reapply the database patchset.
ORA-28509:
Older gateways report this error instead of giving a
deltailed error description.
Resolution:
This error indicates the same as the errors described above.
They can be solved by checking the SQL*Net configuration
for the gateway / generic connectivity setup.

Resolution:
This special combination of errors might occure after applying
the Oracle database and gateway patchset 9.2.0.5 WITHOUT
running catpatch (=the upgrade script of the database).
=> Please run catpatch. If it ran successfully but connectivity
still fails you may run
cathnohs.sql and caths.sql to recreate the HS data
dictionary tables. BUT BE CAREFUL: Running CATHNOHS drops ALL
gateway/generic connectivity related database links!
Hope this helps,

Nvarchar fields using Transparent Gateway for MS SQL

We are using TG to make a number of tables/views available in an Oracle database. The tables in question contain a number of nvarchar fields which are expected to contain Unicode data. These fields cause a number of problems when accessed in Oracle. Firstly, queries returning any nvarchar(x) (for some x) fields hang when they are run in Oracle and it is necessary to reset the connection before running another query! Fields with type nvarchar(max) do come through, however they come through as type LONG, which is very difficult to do anything useful with in Oracle and cannot be searched on.
We are working around the problem by creating views in MS SQL on top of our original tables/views which cast nvarchar(x) to varchar(x). We are then able to query these new views in Oracle, search on text fields etc. However, MS SQL does not properly support UTF-8 in varchar fields and the conversion results in downgrading our data to the latin-1 character set. Note casting nvarchar(x) to nvarchar(max) in MS SQL does not work, the queries still hang. We also have a problem where the length of the nvarchar field in MS SQL is longer than the max supported varchar2 length in Oracle. In this case TG will again provide a LONG converted field.
We would like to know how to get full Unicode data to come across Transparent Gateway. We would be happy to get our data in the Oracle nvarchar2 type, or varchar2 with utf8 would also be fine, ideally with clob/nclob for over-length fields. Alternatively any solution which allows us to access full Unicode data would probably be acceptable. We only need to query the data from inside one ETL package, which will store the transformed data in Oracle, so a solution which involves a cast at this stage would also be acceptable, although obviously having the data show up correctly directly through TG would be better.

Heya,
Here is an example table in SQL Server:
CREATE TABLE [dbo].[tblPnLCostNames](
     [ID] [int] IDENTITY(1,1) NOT NULL,
     [Name] [nvarchar](2048) NOT NULL,
     [Group] [nvarchar](50) NULL,
      [nvarchar](50) NULL,
     [Description] [nvarchar](1024) NULL,
CONSTRAINT [PK_tblPnLCostNames] PRIMARY KEY CLUSTERED
     [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
And in Oracle I did this:
CREATE TABLE "FOR_DW_DEV01"."UNICODE_COST_TEST"
   (     "ID_" NUMBER,
     "NAME_" LONG,
     "GROUP_" VARCHAR2(50 CHAR),
     "CODE_" VARCHAR2(50 CHAR),
     "DESCRIPTION_" VARCHAR2(1024 CHAR)
Now I want to be able to say:
insert into unicode_cost_test ( id_, name_, group_, code_, description )
select "ID", to_lob( "Name" ), "Group", "Code", "Description" from tblPnlCostNames@my_link;
The other fields are shorter and will go straight in to varchar2 fields as UTF-8 with no problems following some tweaks to the gateway ini file. Anything over 2000 characters comes across as a LONG, but trying to use the to_lob function results in "ORA-00997: illegal use of LONG datatype". Doing the same thing using a local table with a LONG field as the source works fine. Is to_lob supposed to work on LONG fields that come across the gateway?
I found this in the 11.2.0.2.2 bugfix list:
10157402 - lob segment has null data after long to lob conversion in parallel mode
(ftp://ftp.hj.se/Oracle/Patchar/11.2.0.2/psu_april_2011/download.htm#BABDIEDD)
Could this be related?
The only way I have found to read the LONG fields so far that works is to use select into, and read each value individually!

SQL Server 2005 (64-bit) - 10.1/10.2 via Transparent Gateway

From what I gather, there is no 64-bit Transparent Gateway for SQL Server. Has anyone used the 32-bit gateway with a 64-bit SQL Server instance? Will this even work?
Also, what are the ramifications for the Oracle instances -- will this setup work with both 32-bit & 64-bit 10.1/10.2 instances?
Thanks!

Can you provide some context as to whay you think this will not work? The gateway is just a client to the 64 bit SQL Server. I'm sure that 64 bit server supports access from clients that are running 32 bit operating systems.

How to know Transparent gateway version

dear all,
Facts:
WIN 2008 AND MSSQL SERVER 2008
AIX 5.3 AND ORACLE 10.1
how i know the version of Oracle Transparent Gateway from :
- Oracle MS SQL Server 2008
- Oracle 10.1
how can i view that ???
thanks a lot !!!

Sorry, but it is not really clear what yo mean with:
how i know the version of Oracle Transparent Gateway from :
- Oracle MS SQL Server 2008
- Oracle 10.1
You can check the vesion of an installed gateway using Oracle Universal Installer which can list which products are installed or you can use opatch lsinventory -detail.
You can also check the listener - it contains PROGRAM=<executble> and now type the name of the executable on the command line. It will now report which gateway and which version you've installed.
If you're interested in which gateway can be used - then the only supported release is 11g which is certified with Oracle 10.1.0.5 + an additional gateway compatibility patch.

Is Transparent Gateway (4.1.1.1) supported in Oracle 8i
