Editor's Notes
- Be a better DBA
- How does it work? – Facets, Conditions, Policies, Demos, CMSEPM – Enterprise policy based management frameworkWhat is coming – Denali + Azure
- Brent Ozar:TEST - PASS OR FAIL
- Limited functionality – CMS, on-demand only (no Agent in Express)No all facets are available for all versions. No all features are available in all version, so test! In 2000 – no DDL triggers! On change prevent – does not work! EPM – Стъпва на SQL Server, Reporting Services, MDW and Powershell (and policy-based management)
- On change – log – only if an event is generated! On prevent – only AFTER trigger! The example of index rebuild! The trigger fires after finished :D DDL Trigger
- Auto close will be deprecated!
- Execution modeMessage numberOn change: prevent (if automatic) 34050On change: prevent (if On demand) 34051 On schedule 34052On change 34053
- Count the suspect pages – executeSQLCheck the freespace on the drive WQLCheck if a counter is below a threshold or a data file has slow response time (in ms!)
- How to add the instance that is the Central server to the monitored -> check donev’s blog!
- MSDB - backup, SPs! Queries
- On-change: prevent mode will fail or perform unexpectedly.DDL triggersCDC and Transactional replication – systanschemas no indexes
- Do the import of all policies -> C:\\Program Files (x86)\\Microsoft SQL Server\\110\\Tools\\PoliciesDatabase Backups and CMS – ADD the central to the tree. How? – Donev’s blog! Checking table names and preventing!
- Only microsoft can add facets! Cannot fail over with the policies – server-based objects! CMS is for that!
