Because the work requires a new database instance in the Oracle 11gR2 database. We recommend that you use oracle to perform the following operations. The order is as follows:
1. Create a parameter file for instance startup. Modify the default parameter file of the program: Rename the rule initSID. ora.
In the/u01/oracle/product/11.2.0/db_1/dbs/directory, use absolute paths as much as possible, and use environment variables such as ORACLE_BASE to report errors.
Example: initcrm. ora
Db_name = 'crm '-- modify
# Memory_target = 500 m -- Comment out
Sga_target = 200 m -- add
Pga_aggregate_target = 60 m -- add
Processes = 150
Audit_file_dest = '/u01/oracle/admin/crm/adump' -- create a directory
Audit_trail = 'db'
DB _ block_size = 8192
Db_domain =''
Db_recovery_file_dest = '/u01/oracle/flash_recovery_area' -- create a directory
Db_recovery_file_dest_size = 2G
Diagnostic_dest = '/u01/oracle' --- modify
Dispatchers = '(PROTOCOL = TCP) (SERVICE = ORCLXDB )'
Open_cursors = 300
Remote_login_passwordfile = 'clusive'
Undo_tablespace = 'undotbs1'
2. Create a directory:
Mkdir-p/u01/oracle/admin/ora11g/adump
Mkdir-p/u01/oracle/admin/ora11g/dpdump
Mkdir-p/u01/oracle/flash_recovery_area
3. Create a password file: The naming rule orapwSID. The directory is still/U01/oracle/product/11.2.0/db_1/dbs/
LinuxLower orapw + Instance name
WindowsUnder pwd + Instance name
$ Orapwd file = orapwora11g password = oracle 4. Create a database instanceSet the environment variable export ORACLE_SID = crm and execute the following command sqlplus/nolog

At this point, the database instance has been created. 6.

If the requirement is not high, we recommend that you use the original listener. The advantage is that the listener changes slightly. The disadvantage is that the public listener of different instances may be inconvenient. Listener. ora SID_LIST_LISTENER =

Note: The Yellow background must be corresponding and cannot be the database instance name. Note that the listener port corresponds to the tns port. When the listener mode is used, @ crm or toad login appears ORA-12537 connection close error, but tnsping crm is normal, set sqlnet. ora parameter TCP. VALIDNODE _CHECKING = no: the problem persists. It should be determined that the listener Configuration problem should be solved in the first way. 7. Stop the instance, start the instance, stop the listener, and start the instance.
