Experience with IDS 15
Tomas Hulek asked for practical experience migrating large IDS 12.10/14.10 databases in place to IDS 15 without upgrading CSDK/JDBC/4GL. Art Kagel said native mode (infrastructure version 1) needs recompiling because sqlca values grew from INT to BIGINT, possibly affecting printf formats. Sebastien Flaesch offered help with Genero clients. Tomas wanted real-world migration experience; none was given.

Hello, is there someone to share practical experience of migration of IDS 12.10 or IDS 14.10 to IDS 15? The path we are now interested in is: in place migration of existing large databases without upgrading CSDK/JDBC/4GL, ie. possibly with switch to native mode, but without using large tables. Thank you Tomas Hulek ------------------------------ Tomáš Hůlek ------------------------------
Tomaz: I can likely help you. If you run v15.0 in native mode (ie infrastructure version 1), even if you only use SMALL tables, you will have to recompile your code due to changes in the sqlca structure where some values have increased from INT to BIGINT. That may also require you to change some printf() format codes if you are using "C" or C++ and printing error reports. Otherwise, no code changes will be required.

Hello Thomas, We have Informix 15 installed for QA / testing purpose with Genero BDL, using CSDK 4.50 and CSDK 15. Feel free to contact me regarding client applications adaptations. Sebastien FLAESCH FOURJS ------------------------------ Sebastien FLAESCH ------------------------------
Hi, thanks very much - this is what is needed according to documentation. But I was also interested in info from the battlefield - has anyone experience o migration of large databasese/applications? What is the practical experience? Any hiccups? Tomas ------------------------------ Tomáš Hůlek ------------------------------
