Question: Which clauses in the CREATE DATABASE command specify limits for the database?

Answer: The control file size depends on the following limits (MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, MAXDATAFILES, MAXINSTANCES), because Oracle pre-allocates space in the control file.

MAXLOGFILES - specifies the maximum number of redo log groups that can ever be created in the database.

MAXLOGMEMBERS – specifies the maximum number of redo log members (copies of the redo logs) for each redo log group.

MAXLOGHISTORY – is used only with Parallel Server configuration. It specifies the maximum number of archived redo log files for automatic media recovery.

MAXDATAFILES – specifies the maximum number of data files that can be created in this database. Data files are created when you create a tablespace, or add more space to a tablespace by adding a data file.

MAXINSTANCES – specifies the maximum number of instances that can simultaneously mount and open this database.

If you want to change any of these limits after the database is created, you must re-create the control file.
