Backward Compatibility of IDS v9.4
Hongsing Tan asked which Client SDK versions work with IDS 9.4, having CSDK 2.3, and wanted an IBM document for management. Jonathan Leffler said CSDK 2.30 should connect to 9.40, but it is out of support and an upgrade is due. He doubted any official statement exists and suggested asking Tech Support. No document was provided.

Hi all, Currently my application is using Client SDK v2.3, while server is going to be upgraded to IDS v9.4. Would anyone have the information about the list of Informix Client SDK version in which the IDS v9.4 is backward compatible to? Your help is much appreciated. Thanks.

CSDK 2.30 should connect to IDS v9.40 without problems. However, you should aim to upgrade to a more nearly current version of CSDK as soon as feasible. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2005.02 -- http://dbi.perl.org/
Thanks for the reply, Jonathan. However is there any release document from IBM about this? I need a solid document in order to have Management approval. Thanks.

I need a solid document in order to have Management approval. Please include enough context for people (such as me) to be able to see what is being discussed.

CSDK 2.30 was released with ESQL/C version 9.21 - hence just about he turn of the millennium. It is therefore high time you upgraded to a newer version, and rebuilt your application. If you want to look at the IBM web site, you'd probably find that CSDK 2.30 is out of support and therefore the upgrade is in order. Further, you are unlikely to find any official statement that you may use it with IDS 9.40. However, empirically and practically, unless you run foul of a bug, the code is likely to continue to work - older versions of ESQL/C have connected successfully to newer servers. If you can't find a document on the IBM web site about it that covers the information you want, try asking Tech Support. If you don't have Tech Support, then you have other problems too, don't you? -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2005.02 -- http://dbi.perl.org/
