hi padmey,
How to mininize down-time?
Major factors depend on your call center operation hours and active running Geneys components.
If it is a 24-hour operation and Genesys CCA are being used, it can be a little messy.
Genesys configuration database
- freeze Genesys configuration a day or so before data migration
- backup/copy the frozen database to new server and restore it before data migration
Genesys log database
- depends on its size and how "critical" this information is in your site
- if it is not classified as critical, freeze and treat it similar to configuration database
- if last-minute messages must be retented, follow steps for "Genesys ODS/DM databases" below
Genesys ODS/DM databases (and other similar databases if applicable)
- it is a dynamic database with respect to call traffic
- agree a cut-off time with end-users and operations
- for non 24-hour operation, let it be the normal non-office start time
- for 24-hour operation, make up a cut-off time
- at the "cut-off" time, do not start database migration yet
- allow around 15 to 30 minutes (assuming default 15 minute reporting interval in CCA) for Data Sourcer to transfer in-memory statistics to database tables
- shutdown Genesys components and start databases migration
Well, if incomplete or missing reports during migration is not a issue (not likely in most sites!), the downtime can be further mininized.
Other advices when performing Genesys databases instances
1. perform some tests before actual data migration
2. list all databases instances, owner IDs, usernames and passwords in current environment
- make sure that identical security settings above is properly configured in new database server
- the TSQL command sp_change_users_login AUTO_FIX, 'my_username' may be needed
(had trouble once related to MS SQL username when transfer database instance from SQL 2000 to SQL 2000;
this command helped to resolve the problem)
3. Estimated backup/restore and verification transaction times
- need to align with normal operation maintenance window
- if not, special arrangement for longer maintenance duration is required
