What Happens

Object needs to be reorganized – DB2 PerfImproper file used for batch run – Log MasterNeed to add several new columns to tables for regulatory compliance purposes – DBA Test tables need to be refreshed – UNLOAD/LOADChange from above needed in production by Mon. – DBA Poorly performing system – Sys and App PerfRequest to fix data – one-off program vs. table editor in Catalog ManagerSpace failure during change on weekend – DBA add space and automatic restart where it left off


But What Does it all Look Like from the DBA’s Point of View?

Let’s take a walk in the DBA’s shoes for a week…


7:00 AM Monday Morning

DBA trudges into his office, coffee cup in hand, only to be greeted by a ringing telephone before he can even switch on his computer:

It’s one of the users in the claims department complaining that she can’t get any work done because the system is so slow…

SmartDBA and BSM

“If there is no immediate need to implement SLM/BSM technologies, companies should focus their attention during the next 12 months on centralizing and consolidating the underlying network, systems, application management technologies and implementing end-user response time measurements. This will enable them to implement fully fledged SLM/BSM projects quickly, once the vendor landscape

has become more stable and more robust best practice scenarios are available.”

Giga Information Group, Thomas Mendel Market Overview 2003: Service-Level Management and Business Services Management Technologies,

Start Implementing BSM today with SmartDBA


The Problem BSM is Solving

› SmartDBA Detects a Problem on a Managed Object, End Users May or May Not be aware anything happened!

› Event is transmitted to DBA Enterprise View Phone Call Pager/Email Alert

› Action is taken Importance or relevance of alarm not always clear No prioritization or scheduling Other stakeholders not aware or informed of the situation

SmartDBA Detects and Alerts(PATROL, Mainview)

DBA acts on InformationManual or Automatic – Uses DBA Tools

Subjective prioritization

End Users UnhappyWhat’s wrong???

SmartDBA and BSM in Action – A Case Study

The Scenario: Trading Floor Application› Processing an order requires customer, quote, order_type,

and order detail information› Business must process thousands of orders a day within trading

guidelines to meet service goals… Failure to meet SLA results in lost revenue, upset customers, and damaged reputation

The Challenge› Deep in the infrastructure, a key

table in the order detail database is filling up, with the potential of halting processing during the most active trading period

› Let’s see how BSM and SmartDBA can keep the business running!


How SmartDBA Works for Business

!

Deep in the infrastructure, a key table in the order_detail database is filling up, which could potentially halt trading!This event is automatically detected and routed to the service model and the DBA.


Business Priorities are Pre-defined

Business relevance criteria is proactively identified in advance to ensure that issues will be resolved seamlessly, based on the priority of the business service that is affected.

!


Business Impact is Assessed

The business service impact of the database event is assessed by the service model.

The service model ensures that the appropriate action is scheduled and prioritized, updating management systems.!


Tasks are Assigned

A work ticket is automatically generated and tasks are assigned to the Database and Storage Administrators with HIGH priority.

!


Action is Taken

then the Database Administrator adds more storage to the problem table.

The Storage Administrator allocates the space,

!


The Result

Bottom-Line: The Trading Floor Application DID NOT MISS A BEAT!

› The database condition was detected before the outage occurred

› The operations team immediately recognized the potential impact to a key business service

› The help desk and support groups reacted to ensure a work ticket was generated and work scheduled and prioritized

› The database administration team had the information and tools to address the problem right away

› The ticket was closed, the system kept running, and the entire IT team was aligned on the highest priority work, ensuring the high availability of a mission critical business service


› SmartDBA Solutions provide a source of rich, intelligent database events today (mainframe and distributed), accessible to BSM through PATROL and MAINVIEW.

› The Service Impact Manager provides a robust toolkit for building models relating IT assets to Business Services.

› Remedy provides a suite of process management tools including Help Desk, Asset Management, and Change Management.

› BMC SIM provides business oriented monitoring and alerting based on events in the infrastructure.
