3. Lesson: Migration Methods
Single Step Migration (Not Supported)
Two Step Migration/ Upgrade

4. Single Step Migration (Not Supported)
Siebel 7.x
Build 3701
Oracle 10
Siebel 8.x
Build 16177
SQL Server 2008
Large Effort to Perform Manual Mapping for Schema Changes
Tables added, merged, split, in-activated, renamed
Columns added, renamed, deleted, moved to other tables
Likelihood of Making Mapping Errors Very High

5. Two Step Migration/ Upgrade
Siebel 7.x
Build 3701
Oracle 10
Siebel 8.x
Build 16177
Oracle 11
Siebel 7.x
Build 3701
SQL Server 2005
Siebel 8.x
Build 16177
SQL Server 2008

7. Lesson: Migrating Siebel Data
Migrating Repository Data
Migrating all Non-Repository Data
Process of Migrating all Non-Repository Data
Migrating User Names / Passwords (Manual Process)
Indexes

8. Migrating Repository Data
Database Configuration Utility in Siebel 7.7
Versions prior to Siebel 7.7 utilized utilities:
Exprep, imprep
Migrate only when repository changes are frozen

9. Migrating all Non-Repository Data
Migrate Seed and Customer Data as one
Insure Siebel Logging, Audit Trail, Triggers are disabled
Migration Tools
Dataexp / Dataimp (Slow but can run concurrent streams) [31 hours for 120 GB in serial migration]
Insert / Select SQL [13 hours for 80 GB in serial migration]
EIM (Does not retain Siebel row IDs)
Consider Vendor Tools on very large tables
BCP
Bulk Loader

10. Process of Migrating all Non-Repository Data
Build the SQL Server environment, configure SQL Server parameters, create the Siebel database (INSTALL.KSH), but don’t install the default Repository
Import customized Repository to SQL Server database and apply any schema extensions (DEV2PROD)
Export data using 1+ DATAEXP process(es) from existing Siebel database for all non-Repository Tables, including EIM, LOVs, Users, etc.
Truncate all non-Repository Tables in SQL Server Siebel database (remove the default seed data)
Import data from DATAEXP process(es) to SQL Server Siebel database using DATAIMP
Audit row counts between DATAEXP and DATAIMP
Collect statistics on SQL Server Siebel Tables
Reconfigure Siebel Server and Client .CFG files to use SQL Server Siebel database
Test
Celebrate!

11. Migrating Usernames and Passwords (Manual Process)
Siebel Logins in S_EMPLOYEE (v6.x) or S_USER (v7.x) are migrated with the process, but not Passwords
Passwords are never stored in the Siebel Tables
Typically use a Database UserID, Windows Active Directory, or some other LDAP solution
Requires additional work if moving from Oracle UserID to any other authentication solution
Likely requires changing Password for each UserID if moving from Oracle UserID to any other authentication solution

12. Indexes Unique indexes should be in place to enforce uniqueness
No demonstrated advantage to building non-unique indexes after the loads
Review low-cardinality Indexes after loading all data
(Information on Index scripts can be found on Technote 6 and 16 on the Student CD)

13. Lesson: Post Migration Issues
General Guidelines
Testing
Tuning

14. General Guidelines
Keep catalog statistics current so Optimizer can do it’s job

15. Testing Execute multiple dry runs to debug the process
Regression testing to ensure functionality has not changed
Perform load and stress testing based on real live environments
Test performance under load by using tools such as Load Runner

16. Tuning Tuning will be needed
How much tuning was done for current implementation?
Oracle uses rule based optimizer
SQL Server uses cost based optimizer
Perform stress testing with full sized database and expected full workload
Avoid having test data fully cached when stress testing – Mimic real production - Do a full tablespace scan on a key table every minute to flush bufferpools

17. Lesson: Migration Tools
Services for UNIX (SFU)
