Oracle 11g EM Dbconsole reconstruction tutorial, 11 gdbconsole
Overview: You can use command lines and graphical interfaces to manage the daily management of oracle databases. command lines include commands such as sqlplus, srvctl, and crsctl, the graphic interface includes 10 Gb EM dbconsole, 11 gb em dbconsole, grid control centralized management, and EM express and cloud control in 12c; this article describes how to install the EM dbconsole tool on 11g.
Tutorial ideas:
1. re-build em
2. Open the em management interface to view
