About every few weeks, we will have received a distress call DBA, complaining about performance issues. “Our Web site as slow as a snail,” they complain, “We are losing customers in serious condition. Can you help?”

To answer these questions, I developed my consulting an analytical process, it allows us to quickly find the cause of performance problems, develop remedial measures and adjustment proposed. The caller inquired about fees and costs very little – they only care about stop loss. When the Certified Specialist or e-commerce application running not achieve the desired performance, organizational and financial benefits will suffer great losses.

Certified Specialist Certification DBA to help avoid disaster and get high performance, and I for our customers, users, and IBM Certified Professional colleagues summarize a fault diagnosis process. The following detailed description of the Certified Specialist and OS / 2 environment using DB2 UDB OLTP e-commerce application 10 of the most important performance improvement skills – and the end part of the conclusion of this article.

1. Monitoring Switch
Make sure the monitor switch is open. If they do not open, you will not be able to get the performance you need information. To turn the monitor switch, issue the following command:

2. Agent
Ensure that adequate IT certification Web site best agent to handle the work load, (such as search 000-550, can be found online). To find out the information agent, issue the command:
db2 “get snapshot for database manager”
And find the following line:
High water mark for agents registered = 7
High water mark for agents waiting for a token = 0
Agents registered = 7
Agents waiting for a token = 0
Idle agents = 5
Agents assigned from pool = 158
Agents created from empty Pool = 7
Agents stolen from another application = 0
High water mark for coordinating agents = 7
Max agents verflow = 0
If you find Agents waiting for a token or Agents stolen from another IBM Certification application is not 0, then the database manager can be used to increase the number of agents (MAXAGENTS and / or MAX_COORDAGENTS take appropriate).
