Thanks for help Tyveleyn, but neither that connection string works, and I got the same error
I'm sure that database name is correct, because if I rename database file (cms.dbs) on server, I got error "database not found or no system permission"
I noticed a strange behaviour by INFORMIXSERVER variable: I thought it defined only the hostname, but if I change it from:
INFORMIXSERVER=cms -> INFORMIXSERVER=only_for_test
I got no errors; so my question is: is an important variable?
I ask this because when informix has been installed, the hostname was different; then we have to change it for network reason, and we replace hostname in solaris config files, in informix config file and in environment variables.
There could be any references to old name written in any binary files or so on, which cause the problem?
Thanks again
Clara
