Assuming that Navicat has been installed and configured, what if I want to connect to an Oracle database? Suppose this Oracle database is the 11g version of the Linux version.
Usually, you will not connect successfully. When testing the connection, Navicat will report an error to you. The error is as follows:
The root cause of this error is that the version of the Oracle client that comes with Navicat is higher than the version of the remote Linux Oracle currently connected. In other words, Navicat supports the server connection of Oracle18 and above by default. Now the Oracle server version of the remote Linux is 11g, which is obviously a lot lower version. To put it bluntly, Navicat 15 does not support the too low version of Oracle.
So, how to configure Navicat so that Navicat supports lower versions of Oracle?
