Before you run the script, you have to make sure that the following environment variable is populated correctly:
OWHOME
OWSYSSID
ORACLE_HOME
OW_HOME_DIR

From your linux shell, please run the following:
Bash$ ${OWHOME}/jre/bin/java \
-classpath ${OWHOME}/jar/com_lgc_ow_devkit.jar \
com.lgc.ow.credentials.OracleWallet \
${OWSYSSID} ${ORACLE_HOME} ${OW_HOME_DIR}

If it’s not exist, it will create ${HOME}/wallet directory with user and password entry. The password created by the script has to be equal as the user. If you have different password value, you’ll need to use the default OpenWorks user dialog.

Before setting up the default temporary tablespace, you have to create the temporary tablespace:
SQL> CREATE TEMPORARY TABLESPACE temp TEMPFILE '/oradata/tempfile_01.dbf' SIZE 10M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 10M;
The tablespace has to be ‘Temporary’ type.

The command to set the default temporary tablespace:
SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp;

And to see if the default temporary tablespace has been configured correctly:
SQL> SELECT * FROM DATABASE_PROPERTIES where PROPERTY_NAME='DEFAULT_TEMP_TABLESPACE';
You’ll see the temporary tablespace there.

In R5000, end user is still able to logon without password but the method is slightly different. R5000 uses Oracle Secure External Password Store. There’s a good tutorial on this created by oracle-base.com.

The wallet directory is set by ${OW_HOME_DIR} environment variable. By default the value is equal as ${HOME}. You would see wallet directory in your home directory. So, if your R5000 environment is set correctly, you will able to do:
sqlplus /@openworksdb

From Control Panel –> Windows Firewall :
1. “Add Port” => 1521
2. “Add Program => browse to the ORACLE_HOME/bin for ” oracle.exe” and “tnslsnr.exe”

Ok, now try to reconnect your client to the Oracle Server, and feel that your firewall configuration works… good luck!

1. Login as sysdba
[ora9i@training01 ~]$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Mon Nov 13 16:23:56 2006
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production

2. Note the user dump directory
SQL> show parameter user_dump
NAME TYPE VALUE
------------------------------------ -----------------------------------------
user_dump_dest string /apps/ora9i/OraHome1/admin/ora
sid/udump

3. Switch logfile several times using the following command.
SQL> alter system switch logfile;
SQL> alter system switch logfile;
SQL> alter system switch logfile;

4. Create the basic SQL script for renaming the SID.
SQL> alter database backup controlfile to trace;
Database altered.

5. Shutdown the database
SQL> shutdown
SQL> exit

6. Find the file created from step 4 in directory in step 2, and rename it to appropriate name.
[ora9i@training01 ~]$ cd /apps/ora9i/OraHome1/admin/orasid/udump
[ora9i@training01 ~]$ ls –ltr
-rw-r----- 1 ora9i dba 1617 Nov 3 16:05 oldsid_ora_7120.trc

[ora9i@training01 ~]$ mv oldsid_ora_32410.trc renameorasid.sql

7. Delete unwanted lines and update as necessary, the result appears as below. Please notify the one in bold.
[ora9i@training01 ~]$ vi renameorasid.sql

8. Create/move directories and rename the datafiles.
[ora9i@training01 ~]$ mkdir -p /apps/ora9i/OraHome1/admin/orasid
[ora9i@training01 ~]$ mkdir /apps/ora9i/OraHome1/admin/orasid /cdump
[ora9i@training01 ~]$ mkdir /apps/ora9i/OraHome1/admin/orasid/udump
[ora9i@training01 ~]$ mkdir /apps/ora9i/OraHome1/admin/orasid/bdump
[ora9i@training01 ~]$ cd /apps/ora9i/OraHome1/database/datafiles/
[ora9i@training01 ~]$ mv oldsid orasid
[ora9i@training01 ~]$ cd orasid
[ora9i@training01 ~]$ mv logg1m1oldsid.log logg1m1orasid.log

[ora9i@training01 ~]$ mv useroldsid.dbf user orasid.dbf
[ora9i@training01 ~]$ mv tempoldsid.dbf temporasid.dbf

9. Update initialization parameter file
[ora9i@training01 ~]$ cd /apps/ora9i/OraHome1/dbs/
[ora9i@training01 ~]$ vi initorasid.ora
*.compatible='9.2.0.0.0'
*.control_files='/apps/ora9i/OraHome1/database/datafiles/orasid/control1orasid.ctl','/apps/ora9i/OraHome1/database/datafiles/ orasid/control2orasid.ctl','/apps/ora9i/OraHome1/database/datafiles/orasid/control3orasid.ctl'

*.shared_pool_size=54525952
*.sort_area_size=524288
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS'
*.utl_file_dir='*'

9. Create password file
[ora9i@training01 ~]$ cd /apps/ora9i/OraHome1/dbs/
[ora9i@training01 ~]$ orapwd file=orapw password=o entries=10

10. Update the environment file in ora9i home directory, and then relogin
[ora9i@training01 ~]$ cd ~
[ora9i@training01 ~]$ vi .login
setenv ORACLE_SID orasid
setenv ORACLE_OWNER ora9i
setenv ORACLE_BASE /apps/ora9i
setenv ORACLE_HOME ${ORACLE_BASE}/OraHome1

11. Running the script.
[ora9i@training01 ~]$ sqlplus "/ as sysdba"
SQL> startup nomount
SQL> @renameorasid.sql
SQL> recover database using backup controlfile;
SQL> alter database open resetlogs;
SQL> alter database rename global_name to orasid;

12. Restart the database
[ora9i@training01 ~]$ sqlplus "/ as sysdba"
SQL> shutdown
SQL> startup

13. Setting up the client
[ora9i@training01 ~]$ cd /apps/ora9i/OraHome/network/admin
[ora9i@training01 ~]$ vi tnsadmin.ora
orasid =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orasid)
)
)

You see that the main steps are step 4 and 7, which create the script and rename.
Okay, you’re now ready with your new name of the database instance. Good luck.
