3. Agenda Why Scope of session Review current process
What this process handles
Practices to be avoided
Demo

4. Why Space full on data drive Space full on log file
Simple recovery during re-indexing
SQL restarts taking very long time to recover
Log backup fails, Backups drive full
Re-indexing caused blocking to multiple session

5. Not performance tuning but maintenance
Scope
Not performance tuning but maintenance
Automating the process for highest uptime
Top to bottom approach
DBA provide recommendations

6. Review current process
Selective re-indexing - All or nothing?
Rebuilding multiple databases
Hardcoded (Do not manage new tables/ fill factor)
Rebuild Vs Reorganize
Online vs Offline indexing
Job fails if one index fails
Weekly schedule, maintenance period
Read only database
Separate script for each server

7. Smart re-indexing What this process handles Selective Reindexing
Handles online vs offline indexing
Reorganize Vs Rebuild
Default set to 90% for fill factor
Clustered and non-clustered index sequencing
Handles blocks/Locks efficiently
Automatically stop itself beyond a threshold

8. What this process handles
Job continues if one index fails
Handles Read only database
Post troubleshooting logs
Can be scheduled daily
Minimize system downtime due to log disk full
Automated log backups
Network backups
Centrally managed
Can be implemented on most of the SQL servers regardless of application type or data size

9. Simple Recovery is not an option
Practices to be avoided
Simple Recovery is not an option
Truncating transaction Log
Shrinking data file
Shrinking log file
Script Review

10. Don’t take everything you hear as true
Summary
Don’t take everything you hear as true
Not tested against XML/Spatial indexes
Better with each release
Keep up to date
Engage with user groups
