In Response To: Re: IDS 940 64-Bit / 32-Bit conversion question (David Griffiths)

Hello David,

No. I have installed the 32-bit Informix into a dedicated directory,
different than the directory were was installed the 64bit version.
I set my new environment to point to the 32bit installation. Under 32bit
environment, I rise the 'oninit -v' command and I'm expecting to bring
up the 32-bit instance using the 32bit Informix binaries.
I do not want to create a new database instance ( a new rootdbs ....). I
would like to access the database I had under 64bit instance only to be
sure that the 32Bit instance it is started well.

I will follow the Art's advice and I will came back here if I still have
problems.

Thank you All.

Best regards,
Elena
