Date Jan 4th 2018 As a dba, I will be executing various scripts in multiple databases. Mostly in non-productions databases. In the event, if any of these scripts were executed inadvertently in the production database, it will be disastrous. There is always a possibility of executing scripts inside a wrong window/terminal, completely wiping out schemas/databases. To deal in such risky situations, I modified the glogin script and color coded the display of environment details as sqlprompt. Before executing any command, I just look at the prompt and make sure, I am logged into the right database. cd $ORACLE_HOME/sqlplus/admin $ cat glogin.sql define _editor=vi column global_name new_value gname set termout off /***PLS MODIFY THE BELOW SQL AS PER YOUR REQUIREMENT OF VARIABLES AND COLOR ***/ select --chr(27)||'[32m'||chr(27)||'[1'||to_char(0)||'m'|| --GREEN COLOR --chr(27)||'[33m'||chr(27)||'[1'||to_char(0)||'m'|| --YELLOW COLOR --chr(27)||'[34m'||chr(27)||'[1'||to_char(0)||'m'|| --VIOLET COLOR chr(27)||'[35m'||chr(27)||'[1'||to_char(0)||'m'|| --PINK COLOR upper(sys_context('USERENV','HOST'))||'-'||sys_context('USERENV','DB_NAME')||'-'||sys_context('USERENV','DB_UNIQUE_NAME') global_name from dual; /***PLS MODIFY THE ABOVE SQL AS PER YOUR REQUIREMENT OF VARIABLES AND COLOR***/ set termout on set sqlprompt '&gname> ' The glogin.sql script provided by Oracle is just right for most of the environments. I only modified the display varialbes in my sql prompt and added required color display as per my requirement. Pls modify the script as per your requirement and test it thoroughly in a lower environment, before using in production dbs. Readers' discretion is advised.
