New version of Oracle Solaris Pre-Flight Application Checker

Some very hard-working folks in my organization, Oracle Systems ISV Engineering, have just released a new version of the Solaris Pre-Flight App Checker. You can get it for free from the Solaris Download Page

As with the original release, this tool is the single easiest way to check your application for Solaris 11 compatibility issues while still running on Solaris 10. This latest release incorporates several improvements:

1. Fully globalized product, currently with support for English,  Simplified Chinese and Japanese 
2. Now detects issues due to static linking of system libraries
3. Now detects mutex alignment issues
4. Now checks usage of private kernel interfaces (binary as well source scanner) 
5. An improved script scanner to flag issues due to usage of removed, relocated commands as well as issues due to usage of new shell ksh93 (instead  of old ksh88 )

Oracle Solaris Binary Application Guarantee extended to Solaris 11

This is Good News.

The Oracle Solaris Binary Application Guarantee now covers both Oracle Solaris 10 and Oracle Soalris 11. Oracle has extended the program through 2013. The program covers a source code guarantee as well as a binary guarantee. Details can be found in the program description.

Today's coolness: ZFS Snapshots and Reproducible test states

I had a lovely 'aha' moment today. This 'aha' is nothing new, except to me.  Today, I tried ZFS snapshots for the first time, and it made my life SO much easier! My thanks to colleague Tom Daly for the suggestion!

We're testing Drupal on Webstack on OpenSolaris. The MySQL database we're using totals about 20GB on disk - not big, but heretofore it was created via a script of MySQL commands, including lots of inserts. To populate the database to a 'fresh' state took about 50 minutes on a Sun SPARC Enterprise T5120.

"Why not try ZFS rollback," asks Tom, nonchalantly. Ding! Aha!

OpenSolaris uses ZFS for everything, even booting. It's the default filesystem type. Our database resides on a ZFS mount (in a Zone, no less, back-mounted from the global zone!). This is a perfect use of the ZFS 'snapshot' and 'rollback' commands. To wit:

First, we need re-instantiate the database only once, and get it to just the place we want as our 'unsullied starting-point' database. 

Time: 1 hour.

Snapshot the ZFS mount in the global zone (before the '@' is the ZFS volume, after is the snapshot name):

bash# zfs snapshot /tank2/db0/data@freshdb      
bash# zfs list -t snapshot
NAME                             USED  AVAIL  REFER  MOUNTPOINT
tank2/db0/data@freshdb              0      -  13.5G  

Time: 10 seconds

Test to your heart's content, mess up the database all your want. Ready for a fresh, unspoiled MySQL database? Well, just roll it back!


bash# zfs list -t snapshot
NAME                             USED  AVAIL  REFER  MOUNTPOINT
tank2/db0/data@freshdb           166M      -  13.5G  -

bash# zfs rollback /tank2/db0/data@freshdb

bash# zfs list -t snapshot
NAME                             USED  AVAIL  REFER  MOUNTPOINT
tank2/db0/data@freshdb              0      -  13.5G  -
Time: 8 seconds

Do this as many times as you need. Fresh databases in seconds, not upwards of an hour.

Just wanted to share...

Drupal on OpenSolaris

The folks over in the Webstack area of OpenSolaris are experimenting adding some higher-level packages to the Webstack repository. Jyri recently added Drupal 6.3 to the repository. If you are using or investigating OpenSolaris, check out the repository. It's a first cut, and intended for now for demos and to solicit input from the Drupal and OpenSolaris communities. Nonetheless, it already installs easily within the pkg framework for OSOL 2008.05 or one of the later development snapshots.

Drupal Performance: Solaris vs Linux

I posted final numbers today as to how Drupal 5 performs on a small Sun server, comparing Solaris 10 to SLES 10 (two of the OS offerings available from Sun on this server). The intent of this test was to see how Drupal behaved under increasing load (in this case, Guest hits on the Main Page). I'm pleased to report that Solaris (with the latest CoolStack) appears to provide better throughput, better response time, and lower incidence of 'Server Busy' errors under load.

Let me, at this point, state for the record.. yes, I would have published these results even if the outcome had been the other way 'round. One of the rules we live by in Sun ISV Engineering Open Source is that of transparency. If we set out to test something, it's to determine and share the reality, not the spin. We had a hunch that CoolStack would provide a huge performance improvement, but that was only a hunch. I'm sure that, at some point in the future, we could also find that a well-tuned Drupal-on-LAMP offering meets or beats this Solaris performance - it is, after all, the same hardware.

Lots more Drupal testing to come from from us in the weeks and months to come. Wanna see something in particular? Let us know here or here or right here in the Blog Comments!

Booting Indiana from USB Flash while in Michigan...

Finally got around to trying the OpenSolaris Developer Preview (aka Project Indiana) this morning... it's cool, it's partial, it's a step in the Right Direction... what really caught my eye was that I could place this CD-sizes image on USB Flash Drives and Boot Live... and it Just Worked in seconds... although on my Toshiba Satellite A205:

  1) Sound doesn't work
  2) Time of day wasn't correct (or asked for initially)

But, really, it's not disappointing at all for Preview 1... I like it!

Second Life goodness

Come see Sun in Second Life... I'm gonna start spending more time there... not surprisingly, I'm "EricReid SunMicrosystems" there...

And, yes, thanks to Dana, I now run Second Life exclusively on Solaris!
