Can Informix access Sql Server table?

Informix: HPUX 11.31 (iiiv3) on HP BL870c IA server IDS 11.70.FC4 SQL Server: W2k8 r2 SP1 on Vsphere 5 cluster SQL Server 2008 r2 One of our developers has asked me to help him setup "whatever is needed" so from Informix he can access data on a SQL Server table. We already have the other direction (SQL server accessing Informix data) setup and working using odbc on the sql server. I'm still clarifying with the developer if he needs only read access or read/write access to the SQL server table from Informix. I don't know if this is possible, is it? If so how do I connect the two databases? What tools/software do I need? A SQL server friend said I might be able to use SQL Server Integration Service (SSIS) but he has never used it so wasn't sure. I have never heard of it so know even less. :-) John Adamski, Sr. Network Specialist Graceland University, 1 University Place, Lamoni, IA 50140 adamski@graceland.edu

The only product that can do Informix "see" other databases, is named Informix Enterprise Gateway. The official link is here: http://www-01.ibm.com/software/data/informix/tools/egm/ Check with your local IBM partner for more informations about it. Regards.

Oh, pooh, we looked at EGM for another project about 5 years ago and was out of our price range. That was what I was thinking that was not going to be able to help the developer. Thanks everyone, I now go get to rain on the developer's parade. :-) John -----Original Message----- From: ids-bounces@iiug.org [mailto:ids-bounces@iiug.org] On Behalf Of Art Kagel Sent: Monday, March 04, 2013 11:12 AM To: ids@iiug.org Subject: Re: Can Informix access Sql Server table?

There is another option. You can use CDC (Change Data Capture) to replicate the SQL Server table(s) to Informix either by coding it yourself - the CDC API is an open one and supported by both SQL Server and Informix so you could make it bi-directional - or using a 3rd party tool - DbMoto comes to mind or IBM's CDC product. This will be less expensive than EGM. Art Art S.

Just one thing - does this need to be from *within* the informix engine ? There are things like FreeTDS which allow access to a SQL Server database from unix platforms via some C code, it should be possible to use that to connect to SQL Server - while being able to talk to Informix using ESQL/C or 4GL (using some C interface functions) On 5 March 2013 13:51, John Adamski <adamski@graceland.edu> wrote: > Oh, pooh, we looked at EGM for another project about 5 years ago and was > out > of our price range.

You wanna' bet :-) CDC is licenced by CPU on both source and target, get any more than one CPU at either (or both) ends and pricing goes though the roof !! It is also not very good at handling a slow WAN link or network interruptions (however brief :-(. Keith On 5 March 2013 14:06, Art Kagel <art.kagel@gmail.com> wrote: > There is another option.

I assume you are referring to the IBM CDC product, but the CDC API and libraries are included in the engine for free and you can use them to develop your own data capture and replication or audit applications. Also DbMoto was certainly less expensive than EGM last time I inquired about it. It will do one-way or bi-directional replication between almost any DBMS and any other DBMS using CDC where it's available and triggers where CDC is not available (the Informix module for earlier releases that did not include CDC uses triggers).

Art, Thanks for this info will research and also pass on to the developer. He is now trying to do what he needs from the SQL server side but is getting and error which I'm guessing has to do with the way SQL server triggers work and it is not 'opening' a connection to Informix. Here is the developers last email to me. Since it sounds like going from Informix to SQL is going to take a while and may include some costly purchases I am trying to go the other way SQL to Informix. Basically just using a simple trigger that takes any rows inserted into the SQL table and writing them to a table in Informix. If I run this code manually with a where clause it works fine insert into CX.cars.informix.cus_cf_answers (SubmissionID, ItemID, AnswerValue) select SubmissionID, ItemID, AnswerValue from CUS_CF_Answers where SubmissionID = '64166500-0CD4-40FF-8989-046263B6E83C' but as a trigger using the INSERTED table I get the error below. The trigger code: CREATE trigger [dbo].[i_cus_cf_answers] ON [dbo].[CUS_CF_Answers] AFTER INSERT AS --do not return any results SET NOCOUNT ON BEGIN insert into CX.cars.informix.cus_cf_answers (SubmissionID, ItemID, AnswerValue) select SubmissionID, ItemID, AnswerValue from INSERTED END Here is the error I get when I insert into the SQL table. The operation could not be performed because OLE DB provider "Ifxoledbc" for linked server "CX" was unable to begin a distributed transaction.

Sounds like a perfect application of CDC and the API is not complex. You create a stand-alone app which uses the API to connect to the SQL Server database, register the tables and operations it wants to be notified about with a callback function for each and wait for messages. It would trap for inserts, updates, and/or deletes take the data it gets and either add it directly to the Informix side with a direct connection, hand it off to a separate thread connected to Informix, or pipe the data to a separate app connected to Informix to handle that side.

Hmmmm, looks like you need to run syscdcv1.sql to generate a database to use CDC API, which if I'm reading right comes with Informix since 11.50. It looks like our ERP did not provide that with the Informix installer they sent us. Oh, yippee I get to go beg them for it and have them turn me down like they did with the data blades. It does seem to be exactly what the developer needs. Thanks everyone for your suggestions.

From what I understand the developer needs from Informix side to read a record on the SQL Server table then update Informix table(s) based on the SQL server record and then finally update the SQL server record it was processed. He's also is trying this from the SQL server side and has the sql that works, but only if he manually runs the sql. If he puts the sql in a job or trigger he gets errors as the ODBC connection to Informix is not opened. At least that is my understanding of the situation/problem.

OK, to maintain the two ODBC connections simultaneously he will have to spawn separate threads before connecting and connect to SQL Server in one thread and Informix in the other passing data and control information between the threads using memory and mutexes. If that doesn't work, he will have to use separate processes, one for each database, communicating via shared memory and semaphores or global mutexes. Either way, I think that he will only need to use CDC on the SQL Server side. Art Art S.

Oops forgot, because SQL Server and Informix use different communications protocols and therefore different libraries, I suspect that you will have to go the separate tasks route. Art Art S.
