MS-DOS – asadmin.bat start-domain –debug domain1
Linux – ./asadmin start-domain –debug domain1

Glassfish starts in 9009 debug port. In MS-DOS mode you can see the following console output,

Waiting for DAS to start ………………………….
Started domain: domain1Domain location: D:\glassfishv3\glassfish\domains\domain1
Log file: D:\glassfishv3\glassfish\domains\domain1\logs\server.log
Admin port for the domain: 4848
Debug port for the domain: 9009
Command start-domain executed successfully.

2. Right click the “Servers” and select “Add Server” menu option in NetBeans if there are no servers connected. Provide the admin user name and password to connect to the remote Glassfish server instance

3. Right click on the project and select “Debug” menu option. Your web project will start in debug mode.

Servers Alive is one such a monitoring tool. With Servers Alive you can have full set of features in evaluation copy and unlimited evaluation time frame. It is easy to install and configure. This is a simple evaluation of this tool. Servers Alive available for download from  http://www.woodstone.nu/salive/download.asp. They have a good documentation online as well as it comes with the installation.

Initial configuration is easy and do it according to the documentation. When you need to configure Servers Alive to monitor your remote system I found 2 ways to do it.

1. Using a remote agent
2. Using Remote DF COM

It is not possible to do much with remote agent and on top of that you need to open ports in your remote system, do some agent installation in the remote system, etc — that’s bad investment with low ROI !!!. Remote DF COM is a small piece of software that need to install where you install your Servers Alive software tool. Then do the 5 min configuration. You can get this add on from http://www.woodstone.nu/salive/addons.asp and download Remote DF COM.

Start Servers Alive and hit Add button from the main window. Then go to General tab. Fill remote server ip address and give it a meaningful name.

Then  go to Check tab. Select External COM and click configure button.  Provide user name and password for the remote server. Then click the small button with few dots next to Check and it pops a dialog box with remote servers partitions.

Select the partition that you need to monitor. Provide monitoring criteria as you want. Ex: less than 20% of hard disk space. Then hit OK button.  Go to Alert, Output and Logging tabs and configure them according to your requirements. Then hit Add button.

Now your remote system is under your monitor !!!

Advantages
* Reduce network usage between clients and servers – stored procedures perform intermediate processing on the database server reducing unnecessary data transfer across the network
* Improved security – database administrator can control the users who access the stored procedure
* Reduced development cost and increased reliability
* Stored procedures are tunable to improve the performance. When same stored procedure executed again, it can use the previously cached execution plans
* Separate or abstract server side functions from the client side
* Access to other database objects in a secure and uniform way
* Can prevent SQL injection attacks
* Unit testable (http://sourceforge.net/apps/trac/tsqlunit/)
* Encapsulation of business logic – less chances to data become corrupted through faulty client programs.

Disadvantages
* Writing and maintaining stored procedures requires more specialized skills.
* There are no debuggers available for stored procedures
* Stored procedure language may differ from one database system to another.
* Poor exception handling
* Tightly coupled to the database system
* Not possible to use objects
* Sometimes it is hard to understand the logic written in dynamic SQL

If you have a KML file, you can load it into your browser like this. This is a simple aspx file that load a KML file.

The same way you can load a KMZ (archive file) file into the browser. All you have to do is just change the file name to your KMZ file.

example :
link.setHref(‘http://localhost:4484/GoogleEarth/doc.kml’);

to

link.setHref(‘http://localhost:4484/GoogleEarth/MyKmzFile.kmz’);

Enjoy Google earth !

You can create a new job and execute this SP periodically.
