Hello,
I have recently upgraded ArcGIS from 10.2.1 to version 10.3. Before the upgrade, I was able to connect to our oracle database using direct connect, after the upgrade I am not able to connect to the same database. Has anyone else experienced this problem? Nothing has changed in our environment and I have checked my co-workers systems to ensure they can still connect to oracle. The version of oracle we are using for direct connect is oracle 10g, 32bit. Any assistance or ideas would be great.
Hi Daniel,
Can you uninstall the Oracle 10g client and install the Oracle 11g full or instant client?
There is a known issue with 10.3 not being able to use the Oracle 10g client. Please see the following GeoNet post: ORA-01455 after upgrading to 10.3
Please let us know the results of the client update.
