Manually create an Oracle 10 Gb database on Linux

After installing the OOracle software on the Linux platform, you do not need to use dbca to create a database, but manually create a database. The main purpose is to understand the operations performed during database creation. 1. First set the SID of the ORACLE to be created. If this variable is set in the. bash_profile file, you do not need to set it.
$ Echo $ cancel_sid
Mdy
If you do not set it, set it manually. If you want to run multiple ORACLE instances on one server, you also need to set it manually.
Export ORACLE_SID = mydb2. create the required diagnostic directories, which are required by the ORACLE process in case of errors or manual tracing.
Mkdir-p $ ORACLE_BASE/admin/mydb/adump
Mkdir-p $ ORACLE_BASE/admin/mydb/bdump
Mkdir-p $ ORACLE_BASE/admin/mydb/cdump
Mkdir-p $ ORACLE_BASE/admin/mydb/udump
Mkdir-p $ ORACLE_BASE/admin/mydb/pfile
Create an oracle data file directory

6. After the database is created, create an ORACLE data dictionary.

SQL> @? /Rdbms/admin/catproc. SQL
SQL> @? /Rdbms/admin/catexp. SQL: the manual creation process of ORACLE is complete.
