Agent configuration parameters
The main file on the Agent side of things with configuration parameters is the emd.properties file. This file is located in the /sysman/config directory.
A lot of parameters are quite useful in an enterprise environment. Just to hi-light some of these, I've compiled a list of 10 common parameters that can get potentially changd and tweaked.

The EMHOME directory is the directory the Agent will use for all files it needs at runtime. The value of that directory can be obtained by issuing this command:

$ emctl getemhome

The Countdown...

10. EMAGENT_PERL_TRACE_LEVEL
Use this parameter in combination with the
All PERL metrics scripts the Agent executes can be told to provide more tracing details in the emagent_perl.trc file with this parameter.
The default setting for the PERL tracing is WARN

9. EMD_URL
The URL the Agent will use to identify itself with. This is the unique identifier the OMS and repository will use to contact this Agent. The value of this parameter is determined at install time, and should never be changed afterwards.
The name of the Agent (oracle_emd target) should match the host and port part of this URL.
If the Agent is secured, both this EMD_URL and REPOSITORY_URL parameter should both be using the HTTPS URI.

When you are familar with the Oracle Database and Middleware stack, chances are that you came across the Enterprise Manager. It comes in many versions for the database or the middleware and differs in its features. If meet someone who talks about Enterprise Manager, it might be possible that this person is talking about something completely different - Enterprise Manager Grid Control. Enterprise Manager Grid Control is the Oracle product for the data center that monitors all databases - and middleware components as well as operating systems. Since the database part is taken for granted, is needs some additional steps to get into the world of centralized middleware management. That's what this book is for - bringing you in the world of middleware management.

The Authors

This book is written by Debu Panda, former Product Management Director of the Oracle Fusion Middleware Management development team, and Arvind Maheshwari, Senior Software Development Manager of the Oracle Enterprise Manager development team.

The Book

Oracle Enterprise Manager conceptionally works for many different management areas. As a user you often think of managing databases with it. This is a wide area and deserves another book. The least known area is the middleware management and that's what the booked aimes for. The first 3 chapters cover the key features of Enterprise Manager Grid Control, Installing Enterprise Manager Grid Control, and Enterprise Manager Key Concepts and Subsystems. The foundation you need to understand the whole software and the following chapters. Read them in order and you are well prepared for the next 10 chapters on managing the various bits and pieces in your data center.

Eighteen years after the world’s first modern cellular phone network went on air in Finland and twenty-two years after the Internet was opened to commercial use, the global explosion of the Internet, of wireless networks, and the rise in broadband capacity has transformed how we connect to the world. New and innovative services can be delivered anytime, anywhere – everything from applications emailing you scans from the copier, to location-based services on your in-car navigation system, to Internet-based services that we use every day. New SAP software enables providers to charge and bill for all these new services.

We have long moved on from using mobile phones just to make calls. We write e-mails, check the headlines, watch videos on YouTube, upload photos to our Facebook profiles, buy the latest apps, pay for bus tickets, or donate money to charity using our mobile phone.

We expect all of these services to be available wherever we are in the world, be it at home using our usual mobile network or on vacation in Venice, in the Bahamas, or the Himalayas. And of course, our mobile phone provider may also be our Voice over IP (VoIP), IPTV, and home Internet provider and we have high expectations for all these services too.

We can upload hundreds of photos to Flickr while downloading a video on demand movie to our television and if we suddenly have a medical emergency, we expect the call to go through. Digital communications has become our gateway to countless new services.

Control room of the future

In a research project, SAP showed how networked software can assist the command center in future cases of civil protection. In the scenario presented at CeBIT – involving a powerful storm front – all the information is gathered in a fictitious control room. There, the emergency services have access to weather data and people’s movements, among other things, so that they can identify the regions likely to be most affected and take preventive action.

In the test scenario, the storm caused several serious accidents. Thanks to the software connection with the hospitals in Berlin, the control center can decide which emergency services should transport what number of patients to which clinics. The software also displays the shortest route to the nearest hospital with free beds, taking the current traffic conditions into account. The SAP Investigative Case Management for Public Sector package forms the cornerstone of the solution, which is usually deployed at police stations and is based on the SAP Customer Relationship Management application. In around two years, it is conceivable that the software will be used in real-life control rooms.

Especially for Patchset 2 of SOA Suite 11g we have put a focus on java development and the developer, which might not have skills to employ WSDL / XSD or XML every day, yet still wants to use the platform for monitoring, versioning and what not.

This, kind of obviously, implies no need to create a WSDL in case you want to wire to an EJB / exposed Spring bean (via ) or want to expose a service Java friendly.

This day is way to nice to run an upgrade workshops :-) 32°C outside (approx 90°F) and the beaches close by sounds VERY tempting. Nevertheless a lot of people came in so we might go for a swim after the workshop as our flight to the Philipines tonight just leaves at 2am in the morning.

We refer in our upgrade talk to gather system (aka workload) statistics to give the optimizer some good knowledge about how powerful your IO-system might be. The optimizer since Oracle 9.2 takes CPU and IO costing into consideration. If you never have taken care on these stats you'll find default values in AUX_STATS$. These values have been defined a few years back. So it might be a good idea right a few days after upgrading to the new release to create them while a real workload is running. Taking these stats does not generate any overhead or performance degredation on your system.

You'll create the system stats while there's workload on the system with:

exec DBMS_STATS.GATHER_SYSTEM_STATS('start');
exec DBMS_STATS.GATHER_SYSTEM_STATS('stop');

You could run this for several hours and you could revert with:

exec DBMS_STATS.DELETE_SYSTEM_STATS;

to the default values.

Zappos.com, the recently acquired online apparel retailer, is known for its quirky company culture, from the top down. Their CEO, Tony Hsieh, has some of the most entertaining tweets. And their new series of commercials featuring the Zappets reflect their fun personality.

Zappets are puppets modeled after actual customer service employees. The callers were actors, but the employees were not in on the joke. Zappos.com is known for their excellent customer service, as I pointed out in this posting. You can read more about the ad campaign here.
