I am trying to connect from ArcGIS Desktop 10.2.2 to Oracle 12c database but the ArcCatlog just crashes every time. here are my environment settings
ArcGIS Machine :
ArcGIS Deskop 10.2.2
Oracle client 12c R1 32 bit
Instance :myserver:1522/orcl ( I have tried using all the usernames and passwords but still fails not only sde)
Oracle Database 64bit 12c
Oracle client 12c R1 32bit
ArcSDE 10.2.2 ( only installation but the schema is not upgraded to 10.2.2, the whole exercise is to upgrade it from ArcCatlog)
Please not that i am able to connect through command prompt to the oracle database without any problems in the ArcGIS Machine.
I have even tried using Oracle client 11g.
Can you please take a look into that and I could not know if ArcGIS 10.2.2 is supporting 12c or not.
Thanks a lot
