The End

This is my final Margin Notes entry at Oracle. The last 11 years and 11 months have been great. I am ready to change horizons. My last day is today, January 14, 2011.

Thanks much for all your comments, questions, and answers. Thanks to everyone I had an opportunity to work with at Sun and now Oracle.

See you around. If you like, you can still follow me on Twitter, or connect with me at LinkedIn.

Enterprise Manager Plug-In for DSEE Now Available

Happy New Year!

Some of you have already seen the news elsewhere, but here it is again if you missed it. Congratulations to Pedro Vazquez, Gary Williams, Guillaume Andru, and the whole team from Enterprise Manager and Directory Server Enterprise Edition who made this release possible.

Last year, just in time for Christmas in fact, Oracle published a plug-in for Enterprise Manager Grid Control. This plug-in is another win for Oracle and Sun integration, adding monitoring capabilities through Enterprise Manager for both the latest Sun and Oracle versions of Directory Server. What follows is a summary excerpt from the documentation.

The System Monitoring Plug-in for Oracle Directory Server collects and displays information and performance metrics for your target Oracle Directory Server including:

  • Directory Server information
  • Performance data about the LDAP operations
  • Performance data about Directory Server instance connections
  • Performance data about Directory Server internal queues
  • Performance data about Directory Server internal resources (caches, locks, transactions, etc.)
  • Data about LDAP errors

You can download Oracle System Monitoring Plug-in for Oracle Directory Server Enterprise Edition at http://www.oracle.com/technetwork/oem/grid-control/downloads/plugin-directory-server-198363.html. The plug-in install guide is available through a link on that page as well.

OpenDS 2.3.0-build002

Download OpenDS Ludo posted the announcement yesterday to the users and dev aliases for the OpenDS project:

We've been pretty quiet since Oracle finalized the acquisition of Sun Microsystems. But as announced by the new owners, the OpenDS project continues as open source. We've been actively working on the code and I'm really happy to say that we are now sharing the result of this work.

This build includes a number of improvements over 2.3.0-build001, as Ludo describes in his mail and on his blog.

The amusing side effect after setting up replication with a previous build on this laptop is that Symantec Client Firewall appears to recognize something in the replication protocol as signature "iNi Killer Trojan horse" activity when using port 9989, and then blocks replication traffic. If only the firewall configuration GUI were as easy to work with as the OpenDS Control panel.

Fast Track to Top Performance

Download DSEE free of charge

For ultimate Directory Server performance you know from reading the Deployment Planning Guide that, "Ideally the hardware on which you run Directory Server allows you to devote enough space to cache all directory data in physical memory."

So once you have the memory in the server, including flash where it makes sense, how do you get all that data into cache as expediently as possible?

Brad Diggs has taken a deep dive into Directory Data Priming Strategies, and come back up to share what he found with all of us. Brad looks at the benefits and trade offs of priming over protocol, and priming with the dd command. He gives you what you need to start getting top performance to your LDAP clients as soon as possible after a server restart.

ZFS For Best Import Rates With DSEE 7

Download DSEE free of charge Wajih Ahmed writes in his blog entry from yesterday on Improving DSEE7 Import Rate Through ZFS Caching about how good a file system ZFS can be for Directory, and how to tune your pool when you have a lot of entries to import from LDIF. Wajih finds the primary cache to be very important to speeding up import. In his blog he describes how he tuned ZFS for best performance, including an appendix with all the nitty gritty details.

DSEE 7 Compression Squeezes Out More Performance

In December and early January,Download DSEE free of charge Brad Diggs took DSEE 7.0 into Sun's Benchmark Center to evaluate performance and scalability on Sun's latest hardware including F20 PCIe flash cards.

Brad's first write up describes how much DSEE 7 compression rocks, "Reducing storage footprint by more than 50% and extending search performance by more than 50%." All the key results are explained in detail. Brad provides the commands to run to get the benefits from DSEE 7.0 in your lab or production environment. A must read for all of you aiming to get the best results from Directory Server 7.0, and to get the most out of your server hardware.

Registering Directory Server Enterprise Edition 7.0 With Windows Services

Download DSEE free of charge This entry covers registering servers and components as Windows Services, so you no longer need to start them by hand on reboot.

  1. Install as described in Installing Directory Server Enterprise Edition 7.0.

  2. Log on as Administrator or a member of the local group of Administrators.

  3. Register Directory Server instances.

    This same procedure also works with dpadm for Directory Proxy instances.

    C:\\Program Files\\Sun\\dsee7\\bin>dsadm stop C:\\DirectoryServer
    Directory Server instance 'C:/DirectoryServer' stopped
    
    C:\\Program Files\\Sun\\dsee7\\bin>dsadm enable-service --type WIN_SERVICE C:\\DirectoryServer
    Instance C:/DirectoryServer registered in WIN_SERVICE
    
    C:\\Program Files\\Sun\\dsee7\\bin>dsadm info C:\\DirectoryServer
    Instance Path:                 C:/DirectoryServer
    Non-secure port:               1389
    Secure port:                   1636
    Bit format:                    32-bit
    State:                         Stopped
    DSCC url:                      -
    Windows service registration:  Enabled
    Instance version:              D-A10

    Do not forget the DSCC Registry instance.

    C:\\Program Files\\Sun\\dsee7\\bin>dsadm stop ..\\var\\dcc\\ads
    Directory Server instance 'C:/Program Files/Sun/dsee7/var/dcc/ads' stopped
    
    C:\\Program Files\\Sun\\dsee7\\bin>dsadm enable-service --type WIN_SERVICE ..\\var\\dcc\\ads
    Instance C:/Program Files/Sun/dsee7/var/dcc/ads registered in WIN_SERVICE
  4. Register your Application Server as a Windows Service.

    How to do this depends on your Application Server. With GlassFish this was so easy I have already forgotten.

  5. Register the Common Agent Container as a Windows Service.

    C:\\Program Files\\Sun\\dsee7\\bin>cacaoadm enable --instance default --file pwd.txt

    The pwd.txt file contains the password of the current user, such as Administrator.


    Important Note: As of this writing, Nov. 20, 2009, Sun is still working on an issue with Common Agent Container in DSEE 7.0 that can crash upon system restart. So until there's a service pack for that, you will need to restart the Common Agent Container by hand after reboot.


    For belt-and-suspenders style administration, after this works you can also provide the password through the Log On tab of the Properties window for the Common Agent Container service in the Services management console. (Run... services.msc)
