No Rest For The Wicked
The wicked fast open source code browser OpenGrok has been updated like crazy lately. First of all the team of Trond, Jorgen, and Knut has set up a Hudson at the famous Norbye site, and fixed a lot of bugs and style for OpenGrok. Myself have made some contribution by adding the ability to run OpenGrok as a JMX agent, and also a TrayIcon based client to connect to it, and by the way adding some bugs as well ;)
To start using the JMX agent, you currently have to check out the source code, but hopefully it will be available soon in the 0.7 release.
Here is a short howto...first you have to set up opengrok and create a configuration file, then start the agent:
java -cp opengrok.jar org.opensolaris.opengrok.management.OGAgentThe agent will now start running indexing, by default every 2 mins. By starting the system tray client as well:
java -cp opengrok.jar org.opensolaris.opengrok.management.client.OpengrokTrayAppAn OG icon will show up in your system tray, where it will mainly be black when everything is ok, red if you are not connected to the agent, and yellow if the opengrok source repository has been updated. Right click to change settings if needed to connect, and if yellow click notifications to see what files have been updated in the indexing of opengrok.
This is just a first implemented task for the client-agent app, we hope to add more features shortly

Delivering The Goods
Mysql Connector/J (5.1.5, JDBC Driver) is delivered to the OpenSolaris source as part of the Webstack project, and should show up in build 92. The JDBC driver will be located at
/usr/mysql/connectors/jdbc/5.1So check out OpenSolaris at build 92 ;)

Rock Hard, Ride Free
Got back from a looong holiday yesterday, which ended with a very good concert with Judas Priest. Here you can watch a video from the concert. As they are one of my musical favorites from ...eh ... 25 years ago, it was great to see them still rocking :)

Cluster One
Check out the new OpenSolaris page and download the new OpenSolaris binary distribution.
You can easily download the integrated MySQL packages by using the Package Manager GUI or simply
pkg install SUNWmysql5
As part of the MySQL packages the MySQL Cluster (NDB) storage engine and management binaries are included. You can use the general documentation available at MySQL.comfor setting up a Cluster . Then you should be ready for high availability MySQL.

When I'm Sixty Four
64 bit MySQL (5.0) is now integrated into OpenSolaris. It will be available in build 87. 64 bit should work with 32 bit generated data-files and vice versa, although MySQL recommends you to do a full dump and reload, at least in production. To enable the 64 bit server in SMF do:
% svcadm disable mysql:version_50 % svccfg svc:> select mysql:version_50 svc:/application/database/mysql:version_50> setprop mysql/enable_64bit=true svc:/application/database/mysql:version_50> quit % svcadm refresh mysql:version_50 % svcadm enable mysql:version_50Also check out the latest Netbeans 6.1 beta with integrated MySQL support.

Let's Get It Up
Some tips around MySQL and SMF on OpenSolaris. You can enable the MySQL server by starting it through svcadm
% svcadm enable mysqlAlthough for current builds since the integration on build 79, you need to do this manual stuff first:
% su - % cd /var % mkdir mysql % /usr/sbin/groupadd mysql % /usr/sbin/useradd -g mysql -d /var/mysql mysql % chown mysql:mysql mysqlSo if your MySQL service is going into maintenance:
% svcs | grep mysql maintenance 11:03:45 svc:/application/database/mysql:version_50You could find out more what happened by doing:
% svcs -x svc:/application/database/mysql:version_50 (MySQL RDBMS) State: maintenance since February 15, 2008 2:25:49 PM CET Reason: Restarting too quickly. See: http://sun.com/msg/SMF-8000-L5 See: MySQL 5.0.45(1) See: http://dev.mysql.com/docs See: /var/svc/log/application-database-mysql:version_50.log Impact: This service is not running.This will lead you to the above log-file, where you could get some useful information.
Another tip is that you can change where your datafiles should be, by doing:
% svcadm disable mysql:version_50 % svccfg svc:> select mysql:version_50 svc:/application/database/mysql:version_50> setprop mysql/data=/export/home/tmp/mysql/data svc:/application/database/mysql:version_50> quit % svcadm refresh mysql:version_50 % svcadm enable mysql:version_50Remember that the directory specified need to be owned by mysql user and group!
Also you can read more about the MySQL integration and SMF at Ritu's blog

Have A Drink On Me
Today I have been at a student day at the Trondheim university, NTNU called ITDagen. The Sun place draw a lot of attention, mostly because we were giving away coffee, but also we were lucky to demo the cool Sun SPOTs.
We also gave away the new Solaris Developer Express 01/08 DVD and a lot of them was really interested. This release also includes the Webstack, so hopefully we can get some users there :)
A lot of students had a lot of interest in Sun technologies, and specially we tried to convince them to use NetBeans instead of certain other products they were using..

Get It Hot
PostgreSQL version 8.3 has been released today. You can find the Solaris bits here. Among new features is the Heap Only Tuple (HOT), which should give substantial throughput improvements.

The Thing That Should Not Be
All things come to an end, and so do old software. By removing the older version of the EOL version 4.0 of MySQL from OpenSolaris, we encourage users to go on to 5.0. From build 79 MySQL 5.0 is now integrated into OpenSolaris. Btw, MySQL 4.0 will not go away unless the ARC case is accepted of course.

Escape
Using SecurityManager with Java and Socket's is not always as easy as it first seems. You would think that when creating a DatagramChannel and operating on that (ie send and receive), you will get the SecurityException if you don't have the right permissions. But no, you have in fact to an explicit check for the permissions you need like this:
SecurityManager security = System.getSecurityManager();
if (security != null) {
security.checkXXX(argument, . . . );
}
And it is the calling Thread that should be checked before doing a DatagramChannel.receive call as this call will hang forever if it doesn't have the right permissions.

Hit The Lights
Hi, I work in the Database Technology Group at Sun Microsystems, and I am located in Trondheim, Norway. I'm currently working with HADB. I'm also doing some work on the OpenSolaris Webstack project with integrating MySQL into OpenSolaris.
