I noticed today that the upload photos feature of Facebook has been changed to use Java.  May be they were using Java earlier for uploading photos as well but hey now it is crystal clear!  And need I say that it is far better than uploading 5 at a time?!  Java, the pervasive!

I am facing a strange behaviour when trying to setup a node which has 2 different versions of mysql running.  The second instance tends to ignore the "socket" directive and uses /tmp/mysql.sock instead of the defined /tmp/<hostname>.sock.  The system has multiple virtual interfaces and conflict is not the issue.

bash-3.00# /global/db/bin//mysqld --defaults-file=/global/db/my.cnf --user=root --pid-file=/global/db/logs/my.pid --basedir=/global/db/ --datadir=/global/db/ &
[1] 13773
bash-3.00# 090427 12:09:40  InnoDB: Started; log sequence number 0 46409
090427 12:09:40 [Note] Event Scheduler: Loaded 0 events
090427 12:09:40 [Note] /global/db/bin//mysqld: ready for connections.
Version: '5.1.24-rc'  socket: '/tmp/mysql.sock'  port: 3306  MySQL Community Server (GPL)

The datadir is owned by the mysql user and problem occurs even if the datadir and the basedir are different.

If you have an idea on what the problem might be, please drop me a note.

In OpenSolaris 11.08, the savecore utility is disabled by default.  Refer to the release note

http://www.opensolaris.org/os/project/indiana/resources/relnotes/200811/x86/#5003

So to enable it, create the /var/crash/<hostname> dir and execute "dumpadm -y".  If you don't do it, you might miss out on finding valuable info on why nodes crashed!

Beware of the sys-unconfig issue in OpenSolaris that results in system boot failure.

I couldn't see the grub menu being loaded as mentioned in the bug report.  So if you are using NIS, then go for a static binding for the first reboot.  :(
