There are a lot of new powerful features in the 12c database but don’t forget about the little features that can make a DBA happier on the day to day basis 🙂
One of my favourites is a new approach to use a DBCA command line interface to create a database in silent mode:
oracle@ryba:~$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName rico -sid rico -createAsContainerDatabase false -sysPassword Oracle123 -systemPassword Oracle123 -emConfiguration DBEXPRESS -datafileDestination /u01/app/oracle/oradata -storageType FS -characterSet AL32UTF8 -nationalCharacterSet AL16UTF16 -listeners LISTENER -sampleSchema true -automaticMemoryManagement false -totalMemory 4096 -databaseType MULTIPURPOSE Copying database files 1% complete 3% complete 11% complete 18% complete 26% complete 37% complete Creating and starting Oracle instance 40% complete 45% complete 50% complete 55% complete 60% complete 61% complete 62% complete 65% complete Completing Database Creation 69% complete 73% complete 76% complete 88% complete 91% complete 100% complete Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/rico/rico.log" for further details.
Nice, isn’t it?
