Trying to track down the source of some persistent performance issues under load with 6.2 RC 1 (haven't had time to upgrade to 6.2 final yet). I'm maxing out at about 30 or so users before dying on a system with 4GB of RAM. The java interpreter is getting pegged to 100% of the CPU, and about 70% of the calls in the stack trace are futex lock errors. A good chunk of the remainder are gettimeofday calls. Potentially useful info (sorry for formatting): % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 72.75 5361.592109 45075 118947 14045 futex 12.28 905.064191 466 1943354 gettimeofday 4.83 356.110745 3709487 96 45 restart_syscall 2.88 212.173358 836 253729 clock_gettime 2.71 199.867690 8802 22706 recvfrom 2.10 154.843342 37841 4092 poll 1.14 84.282371 580 145307 130153 stat Any ideas? thanks, aaron

[xwiki-users] Failed to execute the [groovy] macro while creating an app within a minute

by Peter Duever

Hello XWiki Community, while creating an App within a Minute I get groovy executing failures for each element of the form. It is possible to save and finish the process but I cannot access the editor for the content field. That means I cannot enter default entries. You can see the full failure message at the end of the mail. I googled the problem and found entries for Confluence. Maybe they can guide a way: Now I added the "-XX:ReservedCodeCacheSize=64m" option into JAVA_OPTS. (https://bobswift.atlassian.net/browse/SCRP-129) and It worked for me, I just added XX:ReservedCodeCacheSize to my setenv.sh and until now everything is ok. (https://answers.atlassian.com/questions/13535/problem-with-the-script-runne…) I am running version 5.4.5 Thank you for your time! Best regards, Peter Here is the error which is displayed when I reenter the wizard page for step 2: Failed to execute the [groovy] macro: java.lang.VerifyError: (class:

[xwiki-users] XWiki 5.4.6 standalone: Failed to extract Entity Resource from URL

by Holger Zimmermann

Hello everybody, I just started to check out XWiki 5.4.6 in the "standalone" package (Win7, 32bit). It installed fine and I can play with it locally (http://localhost:8080). If I put "http://<hostname>.<domain>:8080/" in a browser on a _remote_ machine, I get a HTTP error 500 telling me: "Error number 11007 in 0: Failed to extract Entity Resource from URL [http://ricardo_tubbs.eboek.local:8080/xwiki/bin/view/Main/]" Is the standalone version meant to work just locally and that's it? If not: what should I check or fix in any way? Thanks, Holger

[xwiki-users] Monitoring an Xwiki stack

by Bryn Jeffries

Having made my XWiki site available to other users, I was concerned to find that the site became unusable at one point with client connections eventually timing out. I had no way to diagnose the problem, but eventually I managed to make a (slow) SSH connection to the server and restarted Tomcat, and things seemed to settle back to normal. The problem is I have no real sense of what happened and how to prevent it happening again. To that end, I'd appreciate any suggestions for monitoring the server and diagnosing poor performance. What do others typically use? I have an Apache2 server passing wiki page requests to Tomcat7 via an ajp connector, and a PostgreSQL database. My guess is that Tomcat is doing most of the work here so that's probably what I need to monitor the most.

[xwiki-users] [Proposal] Statistics

by Andreea Popescu

Hello everyone, If you’re wondering what kept the QA team busy during the last few days, the answer is a lot of testing and a brainstorming effort in order to devise a series of statistics for the product, which would be featured with the product version 6.2. We believe that the statistics ought to be implemented for the following reasons: a) They would allow for better communication between us and the community b) Each version would be more easily evaluated this way c) The product’s evolution would be more easily observable by tracking the changes in these statistics from one version to another d) A more complete overview on the long-term evolution of the product would be possible, with an opportunity to analyze a series of items in detail We consider some of the above-mentioned items to be quite important. Here is a list of the most important ones: - No. of downloads - No. of active installs - No. of tests executed / added - Jira issues fixed - by resolution, by priority, by type - Jira issues opened - by priority, by type - Closed vs open tickets - Stats for important tags: e.g. ie10, mobile, flamingo - Stats for major features: e.g. flamingo, extension manager, solr - Top overall issues reporters - Top non-XWiki SAS issues reporters - Extensions quality: issues reported (top 10 extensions) - Extensions quality: issues closed (top 10 extensions) - l10n translations: existent, missing - Performance stats Therefore, your opinion on the following issues would be of great use to us: a) The list offered a number of items that we deem important for our measurements and assessments. We would like to know whether you agree with the list and we would like to have your opinion regarding other items that we would consider inserting in the list? b) Where would you like us to publish the statistics and the conclusions that would result from their analysis? We were thinking about the following: - On a ‘Project Health’ page - On a page designated to each product version (each version would have its own page with statistics) - In the test.xwiki.org - Within a blogpost - A mix of the above We await your reply and feedback regarding the viability and usefulness of our proposal. Thank you for your time -- Andreea Zenovia Popescu QA Engineer @XWiki SAS

[xwiki-users] XWiki 6, Java 7 and Red-Hat

by Jeremie BOUSQUET

Dear community, I tried to migrate a test xwiki instance to 6.x on my red-hat linux server, and encountered a (fatal) issue: as it requires java 7, in turn, it requires RHEL >= 5.5 (and I'm on an old RHEL 4.6) due to glibc (thank you, java...). Upgrading red-hat on this server is not an option for now, even if it's way too old I agree, so I hope I'll be able to do this upgrade one day ... :/ But my point is, do you think interesting to add this information in installation guide somewhere ? [1] Maybe there's a better place, or maybe it's not needed at all I don't know... There's already info about java 7 obviously, I'm talking about specific impact for red-hat. WDYT ? Best regards, Jeremie [1] - http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation

[xwiki-users] XWIKI Enterprise Installation Issues

by wolfmav

Hello All: I am running into issues with setting up xwiki enterprise platform on my network. Basically it starts and loads to 100% and not much else I am thinking it's a configuration issue with something I have left out. Here is what I am using for xwiki. Win2012R2 SQL2012 Tomcat/JDBC/JTDS Is their a definitive install guide for using windows/sql server? The stuff I have come across isn't as specific as I would like to see. Any thoughts would be much appreciated and would be happy to post java output from tomcat. -- View this message in context: http://xwiki.475771.n2.nabble.com/XWIKI-Enterprise-Installation-Issues-tp75… Sent from the XWiki- Users mailing list archive at Nabble.com.
