Many software on windows have good alternative software under Ubuntu. Oracle client software PL/SQL is a very powerful software. In ubuntu, the best Russian alternative should be dbvisualizer. The two have their own advantages. The former is quite powerful for Oracle, the latter is a Java application and compatible with multiple databases.
Dbvisualizer on my Ubuntu has always had a problem, that is, the Chinese character is always a "Mouth", whether it is an interface or a dataset. The method for searching from the Internet is either to add the charset to cp936 attribute in the data driver, that is, to modify the Java JDK font. I tried it one by one and ended in failure. This made dbvisualizer the biggest regret on Ubuntu.
This evening, I was planning to port PL/SQL to Ubuntu, but I accidentally found a JRE subdirectory under the dbvisualizer directory, think about whether the modified JDK character set is invalid because dbvisualizer uses its own JRE? So after deleting the JRE subdirectory, we found that dbvisualizer could display Chinese normally. It seems that my guess is correct. When dbvisualizer is started, its own JRE is used by default, and the system's JRE is not used. I just don't know where to set the JRE selection method, or is this method originally a Java application startup method?
