The patch was pushed to 5.0.44 + 5.1.20
[25 Jun 2007 18:50] Jon Stephens
Noted that the new scripts are available in the 5.0.44 and 5.1.20 changelogs. However... according to http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-sci-sockets.html,

"It is possible to use SCI Sockets with any version of MySQL Cluster. No special builds are needed because it uses normal socket calls which are already available in MySQL Cluster."

So why are special build scripts needed? Do the -max builds not include  --with-ndb-sci=/opt/DIS as the statement in the Manual would seem to suggest?

Are there any other errors/inconsistencies on that page that need to be corrected?

There is a difference between using SCI Sockets and using SCI Transporter.
SCI Sockets uses TCP/IP sockets and can be used with any MySQL Cluster version.
However SCI Sockets (SuperSockets) are currently only available on Linux so
on other platforms like Solaris one still has to use SCI Transporter and this
requires a special build since it uses a special SCI Transporter.

I'm sorry, your explanation appears to contradict itself.
[26 Jun 2007 16:31] Mikael Ronström
There is no contradiction, you can read the current doc's also to find out more about
the difference.
What is it that isn't clear?

Thank you for your bug report. This issue has been committed to our source repository of that product and will be incorporated into the next release.

If necessary, you can access the source repository and build the latest available version, including the bug fix. More information about accessing the source trees is available at


Thanks, I didn't realise there was a difference between "SCI Sockets" and "SCI Transporter".

Updated mysql-cluster-sci-sockets section of 4.1/5.0/5.1/5.2 Manuals, with references to resolved issues and new scripts where applicable.
