I found finally the only oracle node that seems to work on windows 7: node-red-contrib-oracledb-mod
But now I fail to connect to the data base because the tnsnames.ora is not found (I think so). I get following error:
"Oracle-server error connection to myDBserver:1554/P54: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"
PATH-variables for TNS_HOME and TNS_ADMIN are set properly and tnsnames.ora is in the admin directory.
Has anyone any idea of how to solve this? Getting Oracle work is a really hard task.
Thanks in advance.
