Split devel and a "backports" project

Hallo, I've got a request from Frank to add CentOS, Mandriva and openSUSE 11.4 into Java:packages. I personally do not like this idea - J:p is intended to be a devel project for Factory. On the other hand, there might be someone will be interested and will take a care. And I don't want to block our community from that. So I am thinking about following concept 1.) create new Java:Factory project -> this will be the devel project for Factory, so only openSUSE_Factory repository will be added 2.) make project link [1] from Java:Factory - Java:???. In this project more targets can be enabled and it can have more maintainers taking a care about such distributions. 3.) the changes in Java:??? will be submitted back to :Factory. If not, then :??? project won't be synced with :Factory. This is a responsibility of those will do the change. I'm waiting on a comments, especially some nice name instead of ???, which is probably not allowed in OBS ;-) [1] http://en.opensuse.org/openSUSE:Build_Service_Concept_project_linking Regards Michal Vyskocil

Better support for third-party JREs
by Michal Vyskocil 24 Sep '12

Hallo all, from time to time I got the complaints from the users want to use our Java packages, but not the JVM itself. As Oracle retired the permission to distribute their own JVM, most of the users want to manually install the Oracle JVM instead of openjdk we distribute. In a past, we have changed a logic of alljava.sh, so it search for jvm in /usr/java/latest and /usr/java as well, so can setup the proper JAVA_HOME for third-party JVM. The next unsolved problem are dependencies. In a bug#776951 I've got an proposal to introduce the fake package with java, but I do not like that approach. We don't need to deal with a dependencies at all, if we intentionally break them. https://bugzilla.novell.com/show_bug.cgi?id=776951 Instead of it, I propose following - change all Requires: java in openSUSE:Factory to Recommends: java. For default openSUSE setup, it won't make any difference. For people wanting to have third-party java installed, they can add lock for distributed JVMs and put their preffered JVM. There is only one problem - users can turn the recommends off, but I don't see that as a probable case for Java software, so I would go forward. Any objections, or other ways to go? Regards Michal Vyskocil

Well, I tried, and failed. This is why I'm asking for help. I created a "java" directory.

As soon as > you know what's required you know what the pseudo package has to provide. Well, I assume that the people that did the packaging of JRE in the past would know how to create that rpm in an instant. For me it is next to impossible. > But this only makes sense if someone is willing to maintain this as I tried to outline in > the mail accessible from the archive URL quoted above. But this fake rpm doesn't need maintenance, it stays the same for the entire life of a distro, I believe. You don't even need to bump versions, because the real rpm containing java is installed by the user, it is his responsibility. The task of this rpm is only to fool yast (or whatever word you like) so that we do not need to install another java. If someone wants to provide one that also does the fetching and installing, that would be wonderful - but it is not really needed. - -- Cheers / Saludos, Carlos E. R.

Question on concurrent disk access
by Uma Maheswara Rao G 10 Sep '12

Hi Experts, I am using Linux for my production clusters. I know When we access the disk concurrently, performance will go bad. (ext3 file system) What are the best practices to avoid this problem? one point I read to tune the schedulers. Other than this, If there are any best practices, Please share. I am trying from my application to reduce the concurrent access.
