Upgrade Path

Direct Upgrade to Oracle Database 10g from 8.0.6, 8.1.7, 9.0.1, 9.2.0 (all patch releases)

“Double-hop” upgrade from other releases– 7.3.4 -> 9.2.0 -> 10.1.0– 8.1.6 -> 8.1.7 -> 10.1.0

Upgrade to latest patch release (e.g., install 10.1.0.3 before upgrading)

Upgrade Methods

Database Upgrade Assistant (DBUA)– Adjusts configuration automatically

Initialization parameters Tablespace sizes Creates files in new ORACLE_HOME

– Interacts with DBA for decisions– Displays upgrade progress– Reports errors– Provides upgrade summary

Upgrade Methods

Manual Upgrade– Run Pre-Upgrade Information Utility

utlu101i.sql Make some adjustments in existing environment,

others in new environment

– Run upgrade script (e.g., u0902000.sql)– Review upgrade results– Run utlrp.sql to recompile invalid objects

Upgrade Methods

Export/Import– Create new 10.1.0 database– Import specific schemas or all schemas– New physical organization

SQL statements– CREATE TABLE .. AS SELECT– INSERT .. SELECT

Upgrade Testing

Testing the upgrade– Use full or subset copy of database– Analyze invalid objects before/after– Test basic application functionality

Testing the upgraded database– Application functional tests– Performance tests– Stress tests

New Oracle Database 10g Features

Component Registry– Tracks version and status of all database

components (e.g., JAVAVM, interMedia, etc.)– Automates conditional component upgrades

Open UPGRADE– Prepares DB instance for upgrade

RESTRICTED SESSION Disables system triggers Enables error suppression for “normal” errors DB operations aware of upgrade

Motorola Upgrade Experiences

Motorola Printrak

Biometrics Identification Solution (BIS) (formerly Omnitrak AFIS)

An integrated suite of applications that allow for the capture, processing, search and storage of fingerprints, palmprints, facial images and other biometric data.

Printrak BIS Overview

1-6 TB of mostly LOB data Application built with:

– J2EE architecture– Java Stored Procedures– Oracle Text– Advanced Queuing– Oracle XDK for Java

Printrak BIS Upgrade Path

Previous generation BIS – Oracle8i (8.1.7.4)– HP Tru64 Unix 5.1B– HP AlphaServer

New generation BIS – Oracle10g – Red Hat Enterprise Linux 3.0– HP Itanium or Xeon

Data Transfer Challenges

Data on different OS and hardware platforms Run by non-DBA personnel Minimize downtime to support

rapid customer system deployment– Original Export/Import, which is the typically used

method in such upgrade scenarios, would take about one week for the larger systems

Recommended process

Upgrade in-place 8i system to 10g Use Oracle Database 10g features to move

data to LINUX– Cross-Platform Transportable Tablespaces– Data Pump Export/Import

In-placeUpgrade New Database

Upgrade on HP Tru64

Used experience gained from new deployments in 10.1.0 before upgrading existing 8i systems

Pre-Upgrade Information Utility– Ran on a reference system to create base scripts

and guidelines– Ran on each deployed system to compare with

reference system and adjust scripts if necessary

Upgrade on HP Tru64 (cont)

Manual upgrade process– Greatly simplified from previous releases– Only marginally different than using DBUA– Finer control of the upgrade process than DBUA– Minimal amount of steps– Easier than installing a patchset in previous

releases

Move Data to LINUX Systems Data Pump

– 7 times faster than original Import for our application– Very easy to use– Recommend to use in small / medium systems

Transportable Tablespaces– 12 times faster than original Import for our application– Involves a more elaborate procedure– Requires Enterprise Edition on the source system– Recommend to use in large systems (if EE installed on the source system)

Lessons Learned

With the greatly simplified 10g upgrade process and new 10g features such as Data Pump and Cross-Platform Transportable Tablespaces, the “indirect” approach we described is much more efficient than the original method of Export / Import for migrating large databases to 10g across different hardware platforms and operating systems.

Lessons Learned (cont)

Read Metalink note 263809.1

“Complete checklist for manual upgrades to 10g” in conjunction with the Oracle 10g Upgrade Guide, even if using DBUA to perform the upgrade.

Lessons Learned (cont)

Special consideration needs to be given to components from later releases that are installed in an 8i database

e.g. 9.2 XDK
