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.

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.

Dw cs5 with existing wordpress site hosted on yahoo need help connecting to existing remote database

I am having trouble establishing a database connection. I can connect with test databases but am having trouble using dreamweaver wtih my existing wordpress website. Am I able to use dreamweaver to edit and live view my changes before uploading the changed files to my live site? Am I able to access my existing wordpress database with dreaweaver? I have imported it to my testing server/database but still seem to be having trouble establishing a connection with it (think maybe my folder hierarchy might be off).
macintosh HD/Applications/MAMP/htdocs/nwm/wp/index.php
"nwm" is the name of the folder that I have copied all of my site files to and the folder I have dreamweaver pointing to. "wp" is what I have all of the wordpress files in (the ones I copied from my yahoo server - including all my current theme files etc.)
I am trying to put the info into the mysql connection dialog box:
Connection Name: Testing (i am assuming this name is for my benefit only and doesn't actually matter)
MySQL Server: mysql
User Name: *****
Password: *****
Database: wp
and am getting this message
MySQL Error#: 2013
Lost connection to MySQL server at 'reading initial communication packet', system error 61
did some google seaches of the error. Tried turning off the firewall, and the advance tab allow mysql incoming (there were 2 one was allow one was not allow. I changed both to allow)
Cant really find anything on yahoo to help me out. Looked in phpmyadmin database named wp: wp_users to get the username and password (which due to previous look for help - I think the password was encrypted cuz it looked like a bunch of mumbo jumbo and am fairly certain I know the correct password).
Any help would be greatly appreciated!! I spent $50 on live chat last night trying to resolve the issue only to find out at the end that the guy really didn't understand my problem and doesn't have dreamweaver. I have also watched countless videos on Lynda.com and have been thru forum after forum. While this problem is only a couple weeks old since I just got CS5. I have been having trouble making any headway learning php since I cant seem to make it past the set up parts. I have done the php / mysql essential training on lynda.com with relative success except that I really dont want to work with any more exercise files so I didn't go on to the beyond the basics. I recently went thru most of the Dreamweaver CS5 and Wordpress 3. Also did the first 4 chapters of Dreamweaver CS5 with PHP and MySQL. I need to start integrating things into my live sites. I am also trying to work my way thru the learning php, mysql, javascript book by o'reily media by robin nixon (as fun as reading a math text book) can't get thru it since I can't relate any of it to my current sites/needs
I am on MacBookPro OSX 10.6.6
Installed MAMP to specification on all 20 tutorials I have tried including lynda.com
Tested the testing server and is working
Just installed dreamweaver cs5
have been using wordpress online to create and edit posts (recently upgraded to 3.? whatever the latest update was online which I believe update the files on my yahoo server?)
Have also installed wordpress on my computer (several times thru each tutorial trying to get this right.)
Am I expecting the impossible?

If wordpress controls it's own connection why am I unable to use the live view. I have synced the remote site to my local computer so all the files should be just as they are online with the exception of the DB which contains most of the content.
I have done all of those steps. I have even exported the database from inside internet phpmyadmin and imported into computer phpmyadmin. When I hit live view I get one of couple of errors.
1. "One is that the dynamic related files could not be displayed due to an internal server error"
At some point I was able to view some sample files inside dreamweaver. But I would like to be able to view my real site files. I was able to "connect" to the local databases (not the copy of my real one - I think that maybe that was because it is somehow nested inside another db an am going try to reimport to new location). And then I changed the host/username/password trying to deal with the internal server error. Now instead I get the cannot connect to the database Error 2016 or whatever from the origianl post. Also, I am using yahoo if that matters and all I can find about what their server name is: mysql - is that correct?
I have been thru this so many times with so many different tutorials I am losing track of what is what.
2. Can I access my remote database within dreamweaver? I do not want to create dummy files (seems to be a waste of time). And while if it had worked exporting/importing a duplicate on to my computer would have satisfied me for a little while it also seems some what counter productive. Since every post and page is different if I were doing a daily updates etc how would I be able to change the formating or design of them if I can't access the remote files. Would I re- import everytime I want to work on it to get current database?
I am trying to be clear. I listed all the specs I could think as listed in your "how to get help fast post" (yes I read that at least twice too) of all of the steps and possible reasons for my problems. I also thought that the forum was on a seperate site so I didn't think it would count as a duplicate. I am frustrated to tears and am feeling incredibly stupid that after all this time and all these tutorials yes you are right I obviously am not understanding what is going on which is why I am on this forum.

Need help connecting a remote MySql database from Iphone

Hi, i need to connect to a remote MySql DataBase in windows from IPhone but..... i'm a noob with Xcode and Objective-C.
Can someone help me or explain me the way to do it plz?

I do not think MCPKit will help you on the iPhone. It is just an Objective-C wrapper around the standard mysql libraries which are not available for the iPhone. Your best bet would be to post on the mysql forums and see if you can get any help.
You can try extracting the mysql client library source code into a separate static library project, and see if you can get it to build for the iPhone.

Need help connecting a MS Sql Database in CF Administrator

Good morning,
I`m hoping someone out there can help me.
I simply want to add a MS SQL datasource within Coldfusion Administrator.
I have connected to it successfully with Sql Server Management Studio, using Windows Authentication.
I`m assuming I need to use Windows Authentication to connect within Coldfusion Administrator
How do I fill out these fields then:
because I am getting this error:
Connection verification failed for data source: test
java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Unknown host: local
The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Unknown host: local
I have also tried it with localhost as opposed to local.
Please help?
Thanks;
Rhonda

I believe you DON'T.
ColdFusion, by default, does not run as any type of user that would work with Windows Authentication. It can be set up to do so, through the windows services panel. You configure the ColdFusion service(s) to "Log On As" some windows domain account with the desired permissions. This is normally done to allow CFML code to access network resources for file operations and the like.
But, I don't know if that is good enough for a connection to a SQL server. I've never had to deal with it myself (I have operations and database administrators types who deal with this for me). But I have read many many times on forums like this that the default security configuration of SQL server does not work with ColdFusion. That one has to set up an alternate configuration in SQL, TCP/IP I think?

One Report needs to connect to 20 different databases

Post Author: macgary
CA Forum: Data Connectivity and SQL
We have 20 identical databases - structurally - but differing in their regional data.
We have created some various reports that need to run against various databases in SQL Server. I would like to avoid having to create 20 variations of each report varying only in their database connections.
Does anyone have an idea of how I can pass the database name into the connection so I can make the one report work on any of my structurally similar databases?
Thanks,

Example needed for connecting to 3 Informix databases

I'm attempting to connect and use 2 different informix databases within the same app.
Connection 1 (Sql selects records where status = 'pending'
Connection 2 (Results from connection 1 are passed to a stored procedure
Connection 3 (Updates Database used in con1 with return values from con2
I'm able to successfully code connection 1 but I'm totally confused on the others.
How do you switch back and forth between each connection?
Thanks in advance
Steve

all you need to do is make 2 connections:
//setup code
Connection conn1 = DriverManager.getConnection(url, user, pass);
Connection conn2 = DriverManager.getConnection(url2, user2, pass2);I have made a couple of classes that can simplifiy this. e.g. the entire code consists of
dbConnection oc = new OracleConnection();
dbConnection pc = new PostgresqlConnection();
oc.createConnection("prodops");
pc.createConnection("test");I havn't made an informix class, but they are simple to do. Give me your email address if you want the classes.

Why use Transparent gateway in stead of heterogenous Connectivity

I am looking for a solution to update data in a AS400 environment through a oracle DB.
I found information to do this. I can use transparent gateways or Generic Connectivity.
Generic connectivity is free and for transparent gateways I have to pay.
But what is the different between the two?
What is the limitation of Generic connectivity?

As you stated, Generic Connectivity is for free - from the Oracle license point of view.
But it requires a 32bit ODBC driver from a 3rd party vendor which might require to purchase a license for the ODBC driver.
The big difference is GC (=HSODBC) is NOT availbale for all platforms (only in 10g for Sun Sparc Solaris, AIX, HP-UX RISC, Linux 32bit and Windows) AND it is bundled with the Oracle database. This means you MUST have an Oracle database installed on the machine where you configure generic connectivity.
The gateway (TG4DRDA) or TG4DB2400 is independant from an Oracle db.
TG4DB2400 is installed on the AS400 machine and you can connect from any Oracle db on any platform to the gateway which then handles the connection.
Similar for TG4DRDA; only the platform availibility is different.
The next big difference/advantage of the gateways is the 2PC (2 phase commit) or distributed update control. You can insert something into the Oracle db and without commiting into the foreign db. Now commit your work and the gateway takes care that the transaction is only valid if BOTH inserts went well.

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

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

Query the data dictionary to figure out the 'HOST'
specified for the database link:
select db_link, host from user_db_links;

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.

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.

cathnohs.sql and caths.sql to recreate the HS data

How to connect to a MySQL database in another server

Dear friends,
I am using Oracle SQL Developer 1.5.3 and I need to connect to a MySQL database located in another server.
I am trying to create a new connection, informing connection name, username and password. Supposing that "Hostname" is the IP server address, I click on "Choose database", but I always receive the following error message: "Status : Failure - Cannot connect to MySQL server".
Please tell me what I should do to solve this situation. Thanks in advance.
Best regards,
Franklin

You need to configure your mysql database to accept connection from your PC for the user you used.
For example,
GRANT ALL ON *.* TO 'someuser'@'somehost';
FLUSH PRIVILEGES;

Connection String to Local Database Problem

I just copied a database on the development server which I am not owner of, but I have rights to the database. I copied it to my local server. Now I need to connect to the local database and I don't know how.
Dim MM_cnnName_STRING
MM_cnnName_STRING = "Provider=SQLOLEDB.1;Password=xxx;Persist Security Info=True;User ID=xxx;Initial Catalog=DBName;Data Source=DevComputerName"
The above is what I used to connect to the development server. How can I figure out the string for my local MS SQL Server

Now I have this error once I try to bring up a page that calls the db
Microsoft OLE DB Provider for SQL Server error '80004005'
Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
/CourseList.asp, line 9

Unable to connect to the specified database

I am evaluating the Oracle Report Builder and I am trying to connect to a Sybase database using ODBC.
I have successfully made a connection with the Query Builder but have not been able to connect with Report Builder.
I get the following error:
REP-0501 unable to connect to the specified database
ORA:00021:invalid session id: access denied.
Any help on this as to what I need to connect to a sybase database would be most appreciated

# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, HOSTNAME, LDAP, EZCONNECT, ONAMES)
so ,what to do ,what to add here??please the problem come back again ,all the offices are ok except that office and they format the machine and change every thing but it stil cant run the report.

Can I use the 10402 oledb provider to connect to an 8i database?

I have a win2008 x64 server with the oracle 92 client installed, and I installed the 10402 client and oledb provider.
I need to connect to an 8i database.
Is this possible? If so, how do I setup my environment to make this work?
Thanks,

Is it possible that the "ALTER SESSION" error (just when the application try to connect to the database) is due to change of the client? in this case 11?Possible? Sure. We'd need to see the actual error and the actual SQL statement that is being issued, however. It could be any number of things.
If I have not other option that to use the client Oracle 9.2.0.4 or higher, can I set something in the Oracle 11 instance configuration in order to accept the "ALTER SESSION" sent by the application?
By the way, there are any "ALTER SESSION" option that was deprecated in Oracle 11 vs Oracle 8?Oracle 8 could mean a bunch of different versions. If you mean, for example, Oracle 8.0.5, there were eleven major releases between Oracle 8.0.5 and Oracle 11.2. You could look through the New Features guides of each major release to look for parameters that were deprecated. But it probably makes more sense to tell us the actual SQL statement that is failing so we can let you know what options you have.

Query about multiple connection pools under one database

Hi,
I have s query about connection pool, now we have a requirement,
we have two schemas in one db, some data store in one schema, some in another schema,
all tables are the same, but data is different, we want to retrive all data under two schemas,
so we need two connection pools under one database,
I have set two system DSN, and each connection pool was mapping to one DSN,
but after I importing tables into RPD, when I view data, there is a dialog let me select connection pool. so If this, when we drag columns in answer, it will definitely get wrong.
so how to realize this function about multiple connection pools under one database and we can get data normally.

Hi,
Try this step
1)Better to create two different DSN for the same database with different user id and password
2)now create multiple connection pool in the same database in u r RPD physical layer .
also refer this link : for imporving performance

Did you go through the various steps in the doc?
There is a gateway specific forum below;
