After launching dmSQL, there are some default settings, such as AUTOCOMMIT, LOCK TIMEOUT, and LINEWIDTH and so on. Some of these settings are saved in the dmconfig.ini file and some of them are saved in DMSQLENV.INI file. So when starting dmSQL, these settings will be loaded from the dmconfig.ini and DMSQLENV.INI file.
When saving settings in dmSQL, these settings also will be updated into these two files, and dmSQL will load them when next starting.
In addition, dmSQL does not allow user to choose which parameter would be saved, so before save settings, user should check that all the current settings are the expected ones.
