SAP ERP 6.0 or SAP ECC 6.0 or it might also called mySAP ERP 2005 was powered with some new transacion code. Some code are for Basis. Some tcode is created to simplified Basis work. One of tcode which I have found is DBACOCPIT.
DBACOCKPIT is new tcode but actually old ones since it actually only summarize some tcode and gather them on one screen. From DBACOCKPIT screen you can go to ST04 screen, DB02 screen, DB13 screen, and etc. You can get information and statistics of your database since database startup on ST04 screen. DB13 gave you access to database schedule activities such as database backup (whole, full, or incremental), archive log backup, database update statistic, database check, and etc. DB02 gave you information about current size of database, tablespace, critical tables and indexes, and etc.
Well, DBACOCKPIT is very useful tcode for Basis.
