Upgrading Oracle 9i Software to Oracle 10g
UPGRADING ORACLE 9I SOFTWARE TO
ORACLE 10G
IMPORTANT: It is strongly recommended that you clone your database and perform a test upgrade on the
clone database first. This allows you to become familiar with the process without risking
loss or corruption of data if problems occur during the test upgrade.
PREREQUISITES
Your database server and application server(s) must meet the system requirements described in the
appropriate version of the Installation Guide.
PRE-STEPS
Before you begin the upgrade, do the following:
•
Perform a full back up of the WebCT database.
•
Perform a system backup of the database server, including the directory that contains the Oracle
software.
•
On Solaris and Linux, you should also back up /etc/oratab and /etc/oraInst.loc.
•
On Windows, you should also back up the Windows Registry.
•
Make sure that you have installed Application Pack 1 for Vista 4 or Campus Edition 6 as described in
either the release notes (for an upgrade) or the Installation Guide (for a new installation).
•
If Oracle is running on Linux, make sure /etc/sysctl.conf contains the following lines:
kernel.sem = 250 32000 100 128
kernel.shmmax = 4294967295
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
IMPORTANT: The kernel.shmmax parameter specifies the maximum shared memory segment size.
The value given here (4294967295, approximately 4 GB) assumes that your database
server machine has 4 GB of physical memory. If you have more than 4 GB, this value
should be adjusted so that it is greater than or equal to half the server's physical
memory. Otherwise, the Oracle installer will issue a warning.
3
Upgrading Oracle 9i Software to Oracle 10g
After making these changes, you must either reboot or execute /sbin/sysctl -p as root.
•
If Oracle is running on Solaris, make sure /etc/system contains the following line:
set noexec_user_stack=1
After making this change, you must reboot.
•
Check for invalid objects in the database and recompile them if necessary.
•
Gather schema statistics.
•
Edit privileges for the wctsupport and connection pool users.
Gathering Schema Statistics
Before you perform the upgrade, it is strongly recommended that you collect optimizer statistics for the
standard schemas. Start SQL*Plus and execute the following:
connect / as sysdba
spool gdict
grant analyze any to sys;
exec dbms_stats.gather_schema_stats('WMSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('CTXSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('XDB',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('OUTLN',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('DBSNMP',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('SYSTEM',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
exec dbms_stats.gather_schema_stats('SYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
spool off
Editing User Privileges
Oracle 10g includes changes to the privileges for the CONNECT and RESOURCE roles. As a result, it is
4
Upgrading Oracle 9i Software to Oracle 10g
necessary to modify the permissions for the connection pool users and wctsupport.
1. Start SQL*Plus and execute the following:
connect / as sysdba
revoke connect from <connection_pool_user>
/
revoke resource from <connection_pool_user>
/
grant create session, alter session to <connection_pool_user>
/
grant create sequence, create synonym, create table, create view,
create procedure, create trigger, create type to <connection_pool_user>
/
grant create cluster, create database link, create operator,
create indextype to <connection_pool_user>
/
grant query rewrite, unlimited tablespace to <connection_pool_user>
/
revoke connect from wctsupport
/
revoke resource from wctsupport
/
grant create session, alter session to wctsupport
/
grant create sequence, create synonym, create table, create view,
create procedure, create trigger, create type to wctsupport
/
grant create cluster, create database link, create operator,
create indextype to wctsupport
/
where <connection_pool_user> is the name of the database connection pool user.
NOTE:
You may see errors after the revoke statements are executed. They can be ignored.
2. Execute the following:
connect ctxsys/<ctxsys_password>
grant execute on ctxsys.webct_clob_search to <connection_pool_user>$PF
/
grant execute on ctxsys.webct_blob_search to <connection_pool_user>$PF
/
where <ctxsys_password> is the password of the ctxsys database user and
<connection_pool_user> is the name of the database connection pool user.
UPGRADING TO ORACLE DATABASE 10G
The general steps to upgrade Oracle 9i to Oracle 10g are:
1. Install the Oracle Database 10g software and all required patches.
2. Upgrade the database using the Database Upgrade Assistant.
3. Apply Oracle patch 5005469.
4. Update the initialization parameters.
5
Upgrading Oracle 9i Software to Oracle 10g
Installing Oracle Database 10g Software
For detailed information on installing the Oracle 10g software and required patches, see the appropriate
version of the Vista or CE Installation Guide.
Upgrading the Database
1. Make sure the WebCT application has been shut down.
2. Log in the database server machine.
NOTE:
On Windows, log in under an account that has administrator privileges on the
machine. On Linux and Solaris, log in as oracle.
3. Make sure that the WebCT database is running.
4. Change the ORACLE_HOME environment variable to point to the Oracle home directory that was
created during the Oracle 10g database software installation.
5. Launch the Oracle Database Upgrade Assistant (dbua).
Linux/Solaris
From a terminal window, execute $ORACLE_HOME/bin/dbua
NOTE:
Windows
Make sure that $ORACLE_HOME points to the new Oracle 10g
home directory.
From the Windows Start menu, choose Programs->Oracle ORACLE_HOME_NAME->Configuration and Migration Tools->Database
Upgrade Assistant
6. From the Welcome screen, click Next.
7. From the Databases screen, select the WebCT database you want to upgrade and click Next.
8. The dbua performs various checks on the database to ensure that it can be upgraded. During the
course of these checks, you may see warning messages. Follow the on-screen instructions and
perform any necessary steps to correct problems if required.
NOTE:
You may see warnings that the default privileges for the CONNECT role have changed
and that the optimizer statistics are stale. Click Yes to ignore the warnings and
continue the upgrade.
9. From the Creating the SYSAUX Tablespace screen, click Next.
6
Upgrading Oracle 9i Software to Oracle 10g
NOTE:
The new SYSAUX tablespace will be used to store Oracle product-specific data that was
previously stored in separate tablespaces, including statspack statistics. For more
information, see the Oracle Database Administrator's Guide for Oracle 10g (available
from Oracle).
10. From the Recompile Invalid Objects screen, make sure Recompile invalid objects at the end of
upgrade and Turn off Archiving, for the duration of upgrade are both selected. Make sure Degrees of
Parallelism is set to 1. Then click Next.
11. From the Backup screen, make sure I have already backed up my database is selected and click Next.
12. From the Management Options screen, make sure Configure the database with Enterprise Manager is
not selected and click Next.
13. In the Summary screen, review the summary information. If you need to make any changes, click
Back to return to the appropriate screen. Otherwise, click Finish. The upgrade begins.
NOTE:
During the upgrade, you may see a warning about a unique key constraint violation on
CTXSYS.DRC$OAT_KEY. This error can be ignored.
14. When the upgrade is complete, the Upgrade Results screen appears. Review the upgrade results. Then
click Close.
Applying Oracle Patch 5005469
IMPORTANT: Currently, the OPatch utility cannot be used to apply this patch. You must apply it
manually as described in this section.
To apply patch 5005469, do the following:
1. Extract the patch to a temporary directory.
2. Open a console window and change to the temporary directory.
3. Execute the following:
Windows
sqlplus "/ as sysdba" @.\5005469\files\ctx\sample\script\drkorean.sql
Linux/Solaris
sqlplus "/ as sysdba" @./5005469/files/ctx/sample/script/drkorean.sql
Updating Initialization Parameters
7
Upgrading Oracle 9i Software to Oracle 10g
1. Create the following directory:
Windows
%ORACLE_BASE%\admin\<oracle_sid>\adump
Linux/Solaris
$ORACLE_BASE/admin/<oracle_sid>/adump
where <oracle_sid> is the Oracle SID of the upgraded database.
2. Start SQL*Plus and execute the following:
Windows
Linux/Solaris
connect / as sysdba
create pfile='c:\pfile.ora' from spfile;
connect / as sysdba
create pfile='/tmp/pfile.ora' from spfile;
This creates the pfile.ora text file, which contains all the database's initialization parameter
settings.
3. Open pfile.ora in a text editor. Then search for and remove the following initialization
parameters:
•
*.sessions=<value>
•
*.log_buffer=<value>
•
*.log_archive_dest_state_2=<value>
4. Add the following lines:
*.audit_file_dest='<oracle_base>/admin/<oracle_sid>/adump
*.db_recovery_file_dest='<oracle_base>/flash_recovery_area'
*.db_recovery_file_dest_size=2147483648
*.recyclebin='OFF'
where <oracle_base> is the new Oracle base directory and <oracle_sid> is the Oracle SID of
the upgraded database.
5. Make the following changes:
*.compatible='9.2.0.0.0' -> *.compatible='10.2.0.1.0'
*.log_archive_format='%t_%s.log' to *.log_archive_format='%t_%s_%r.log'
6. In SQL*Plus, execute the following:
Windows
shutdown immediate
connect / as sysdba
create spfile from pfile='c:\pfile.ora';
startup
8
Upgrading Oracle 9i Software to Oracle 10g
Linux/Solaris
shutdown immediate
connect / as sysdba
create spfile from pfile='/tmp/pfile.ora';
startup
This updates the database with the changes made to pfile.ora.
