Sybase DB upgrade from 12.5 to 15

Author: (discooctopus)


We are on U9.3.02.

We plan to upgrade our Sybase version 12.5 to version 15.

U9 requires SYB driver U4.0 for Sybase 12.5 and SYB driver U4.1 for Sybase 15.

I would like to know if anyone has performed such an upgrade, and if there are any tips, tricks, or issues that people have encountered that may be of help / concern?



  1. Hi,

    I migrated last year from 8.3.02 to 9.3.01 and at the same time from Sybase 12.5 to Sybase 15.0.3.
    The migration to Sybase 15 was very easy and I don't have any problems.
    The only things I did in Uniface 9.3 was to change the driver to U4.1

    There was a lot of work for migrating sybase (installation, modifying scripts and so on) but I can
    tell you that there really no problems within Uniface.

    Many luck

  2. Hi, I run into an error while I was trying to upgrade from 8.4.04 to 9.5.1 with Sybase 15.5. The new 9.5.1 version seems to work with U4.0 but if I update the driver version to U4.1 then it fails with the error below: Unable to load usyb41; error 126 ('The specified module could not be found.') *** The DLL could not be loaded either in the USYSBIN directory or via the PATH variable. *** Check if its directory is in the correct place in the PATH variable. Current PATH shown below. Any thoughts? Thanks, Zoltan

  3. Hi Zoltan To use U4.1 driver for Sybase 15 I need to set the following: In Path I add C:\sybase15\OCS-15_0\lib3p;C:\sybase15\OCS-15_0\dll;C:\sybase15\OCS-15_0\bin; and I also need the following two environment variables: SYBASE C:\sybase15 SYBASE_OCS OCS-15_0 At least patch E107 is needed. Most recent patch for Uniface 9.5 is E117. You can download it from Regards, Peter
