Heterogeneous Services with HTMLDB

Hi All,
I was wondering if HTMLDB exposes Heterogeneous Services connectivity to other datasources?
For example...if I create a DB Link to DB2 via a gateway is this information exposed in HTMLDB?

Howard,
Nothing HTML DB-specific about your question. You might try this forum:Heterogeneous Connectivity

Please help me to get over this.

Help with heterogeneous services

Hello.
I have been asked to try to create a dblink from an oracle 9.2 database on a solaris machine to a mysql 5.1 database on a windows xp machine.
I need to know what software I need to get and install on both machines and what settings on the oracle server are needed.
I just hope that someone who has done this before can help me.
Thanks in advance.

Hi,
If you are looking for a tutorial sort of thing for Heterogenous Services than this thread over Asktom is a good resource. Look inside it an example given by Tak Tang for connecting Oracle Database with MS Excel. Take it as a reference to do your work.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:4406709207206
And for the Heterogenous Services, look at the doc guide of it here,

I have checed the tnsnames.ora / listener.ora and they are seems OK
tnsping is also working fine on HS
Thses are the steps that I followed :
1. setup system DNS
2. configure Oracle HS Initialization File under $ORACLE_HOME/hs/admin
3. configure tnsnames.ora under $TNS_ADMIN
4. configure listener.ora under $TNS_ADMIN
5. craete db link
6. querying db link gave the following error

Hi,
The gateway file initMYSQL_LOCAL.ora should be placed in the directory -
$ORACLE_HOME\hs\admin
which is the expected location. In your setup this should be -
C:\app\product\11.2.0\dbhome_1\hs\admin
If the file is already in that location then make sure that in the listener.ora and tnsnames.ora that in each section every line except the first line starts with at least one space -
SID_LIST_LISTENER =
<space>(SID_LIST =
<space>(SID_DESC =
LISTENER =
<space>(DESCRIPTION_LIST =
Tnsnames.ora
MYSQL_LOCAL =
<space>(DESCRIPTION =
<space>(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
However, there is also a problem with the tnsnames.ora file. You have -
Tnsnames.ora
MYSQL_LOCAL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_LOCAL)
(HS = OK)
) <=== move this bracket
but it should be -
Tnsnames.ora
MYSQL_LOCAL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_LOCAL)
) <=== bracket moved here
(HS = OK)
Of course, with spaces as shown above. They are often lost in the forums.
You may also need to change -
(HOST = localhost)
to -
(HOST = <actual host name>)
but it depends on your setup.
Try these changes and let me know what happens.
Regards,
Mike

Generic Heterogeneous Services

I’m trying to implement Heterogeneous Services using the generic
ODBC driver supplied with Oracle 8.1.7. I am attempting to
connect to a ForPro database running on a NT server from Solaris
5.7 running Oracle 8.1.7. Up to this point I have not been able
to properly configure the Listener so that it will run with the
non-Oracle listener information in the Listener.ora file. I get
an error (TNS-12545) “Connect failed because target host of
object does not exist”
Has anyone tried to connect to FoxPro on an NT server?
Were you able to do this with the generic ODBC driver supplied
by Oracle?
Can you post a copy of the relevant sections of the Listener.ora
and tnsnames.ora files?
If using an after-market ODBC driver, which one did you use?
Any help supplied will be greatly appreciated. I have very
little time to determine if it is possible to make this
connection and to get it working.

I wouldn't think so these days ... however, you could try posting this in the heterogeneous services - which is somewhere on OTN.
If it we me, I'd convert the DBF into something easier to use with Oracle : like XML or CSV

Heterogeneous Services & SQL Server

I understand that connecting an Oracle database to a SQL Server database can be done using the Heterogeneous Services which will set up a Transparent Gateway to the SQL Server data. Where can I get the agent needed to connect the two though? Are there different agents for different Oracle/SQL Server version combinations?
I have the paper 'Oracle8 Distributed Database Systems Release 8.0 A58247-01, Chapter 7: Administering Oracle Heterogeneous Services', and it is very helpful in getting the basics, but I need more info for my particular situation. Supposedly the agent has an Installationand User's Guide which would assist me also.

Do you have any pending statements in dba 2pc pending?
Your init parameters seems good. you need to check with the network guys for the packages sent from Oracle is received by sql server and vice versa. Hope there is no block on redirect ports.
You can enable tracing and see if you get any valid points in this direction.
As you said about trigger, look for the privileges in sql server does the user you are connecting has all the privilege on the associated tables. Also the conditions on the trigger has to be satisfied for the execution.
Also you need to add some HS parameters for the recovery in case you may need.

Heterogeneous Services ODBC to MS SQLSvr - ORA-00904 error

Hello, I have successfully setup a heterogeneous Services ODBC to MS SQLSvr using the steps outlined at http://www.orafusion.com/art_orahs.htm.
My problem is, the only queries that run without errors are SELECT * FROM tablename@xxx. When I try SELECT colname FROM tablename@xxx I get an ORA-00904: "colname": invalid identifier. Any thoughts?
Also, will I be able to update MS SQLSvr tables using this link?
Thanks.

Hello, Your suggestion worked. Even though all the column_names are lower case, if I surrounded the column names with double quotes the query would work.
Another question. I'm wanting to update a SQLServer table with data from a Oracle table using a query like:
INSERT INTO sql_table@xxx
SELECT * FROM oracle_table ;
Is this possible? I'm getting a "ORA-02025: all tables in the SQL statement must be at the remote database" error message which looks like I can't.
Thanks.

Heterogeneous Services & Oracle Generic Connectivity For DBF file?

Dear All,
Can We Create dbf file directly means without using CSV file?
Can we use Heterogeneous Services & Oracle Generic Connectivity for creating dbase DBF file or Writing in dbase DBF file?
I have used it for Excel and Access for connectivity with Oracle 9i
but I dont have any idea about dbase DBF file?
Any help in this reagards will be highly appriciatalble.
Thanks
Rana

HSODBC/DG4ODBC is generic connectivity and you find the generic setup in:
Note.109730.1 How to setup generic connectivity (HSODBC) for 32 bit Windows (Windows NT, Windows 2000, Windows XP, Windows 2003)
There is nothing sepcial for DBF's. Just define a system ODBC DSN using a DBASE ODBC driver pointing to the DBF file.
The rest is absolute similar to the note.
If you have already a running HSODBC/DG4ODBC the quickest test is to just define a new system dsn for the DBF file, then change in the init>hsodbc/dg4odbc>.ora file the HS_FDS_CONNECT_INFO parameter pointing to the newly created system DSN. Last step is within the Oracle db to define a database link.

Running INSERT into SQL Server using Heterogeneous Services

I am running into a show stopping issue trying to insert into a SQL Server table via Oracle.
Basically, I have my Heterogeneous Services set up correctly and I am able to hit the SQL Server database with my INSERT statement. But what is happening is I seem to be manually controlly row locks. I believe HS is issuing the following to the server before my INSERT statement is run:
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
SET IMPLICIT_TRANSACTIONS ON
Also, it does not seem that I ever issue the COMMIT TRANSACTION
command. This leaves the row locked forever... unable to complete the
insert generating an error and not inserting my record.
I would GREATLY appreciate any help you could provide, this is a critical issue.
Thanks in advance,

Oracle heterogeneous services in 10g r2

The dba configured oracle heterogeneous services to connect to a SQL Server database.
The purpose of doing this is to select from a view in SQL Server.
We are able to select. But as soon as a where clause is introduced, the session just hangs.
So we thought it might be because we are accessing a view.
We then created a table in SQL Server and inserted all the data into the table. However, the select with a where clause does not work.
We then created a table in Oracle and selected from the view in SQL Server to insert data into the oracle table . Once the data is in an Oracle table, we are able to select and use a where clause. We do not want to bring data into Oracle as the data architect is trying to avoid a duplication scenario.
The DBA is not able to find what is wrong. Can someone please help. Have you seen a similar issue?
The oracle version is 10.2.0.4 and sql server is 2000.
Thanks,
ksd

If the application is using sequences, it cannot require that values are not skipped. Oracle sequences will never be gap-free. And assuming that there are multiple users, the order of transactions and the order of sequence generated values cannot be guaranteed.
I suppose that if your failover process was manual and scheduled and the downtime window was sufficient (i.e. you're failing over because you're taking one server down for scheduled maintenance, not because there was an unexpected fault), you could set up a script that would shut down the application, iterate over the sequences on the master getting the next value, alter the local sequences (presumably by altering the increment, selecting the next value from the local sequences, and returning the increment to 1), and then allow the application to start on the new server. If your downtime window is sufficient, when the primary has an unscheduled failure, you could potentially do a SELECT MAX(primary key) on each table on the local system (while the application is down), alter the sequences and then allow the application to start running. Neither is a particularly pretty option, and the latter option can be quite expensive if there is a lot of data.
