High CPU usage when Disk Queue is very high. (Domino + Windows)

    Kenio Carvalho  15 July 2015 17:12:26
    A customer has one Domino cluster with 2 members on a virtualized environment (VMWare). it is not a big environment (1600 users) but after 3 months working well some thing happened and the system does not work well.

    During a period of 4 hours (9 am to 13 pm) the CPU of one cluster member goes to 100% and the cluster does not send users to the another member.

    I check everything possible (this server has 800 GB of mailboxes) and run some administrative commands.  I raise a PMR and sent NSD's.

    IBM told me  that the windows kernel is consuming a lot of CPU and Domino was not the cause, but this machine only run Domino.

    We talk a lot about the problem an after some verification at the windows 2012 level, we saw a high disk queue lengh (between 8 and 12).

    The solution:   The VMWare administrator put each disk on different LUN (We have 3:  OS, Data and Tranlog).

     Until now the machine works well and the disk queue length is bellow 1,2

      IBM Domino Web Server Cross-site Scripting Vulnerability

      Kenio Carvalho  18 June 2015 11:41:40
      IBM Domino Web server configured for Webmail is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials. Note that Domino servers configured for iNotes are not vulnerable to this attack.

        Performance problems with Full Text Indexer

        Kenio Carvalho  17 June 2015 11:07:13
        Last week two clustered servers are facing performance problems. The cpu was very high for 2 hours and the disk queue above 5,48.

        During the problem the command set config UPDATE_NO_FULLTEXT=1 was issued and the cpu and disk queue decrease

        To schedule the full text index i use the this TN

            I like the IBM Knowledge Base

            Kenio Carvalho  2 June 2015 21:00:43
            On April IBM stop the updates for IBM Knowledge Base  (lotuskb.nsf). I use this database on a daily basis. But now the beloved database was not updated anymore.

            The new way to work is Google or IBM Support Portal
            I like  the database.
            I need offline access, some customers doesn't allow aliens laptops on their networks.

            I build a java project to update the legacy lotuskb.nsf.  

            1 - I get the URLs of the support feeds
            2 - Read the feeds and extract the URL's to technotes
            3 - Parse the html of the technotes and store them into the lotuskb.nsf.

            I use several packages like JSOUP and JERICHO to parse and render the html. It is not perfect but i got the documents again on the lotuskb.nsf

            Thanks to Nathan Freeman for the article about running Domino API on eclipse

            The eclipse project is here

                Google are removing support for Java, and other plugins that use NPAPI

                Kenio Carvalho  7 May 2015 21:13:57
                Google are removing support for Java, and other plugins that use NPAPI, from Chrome 45, which is available in September 2015.
                http://www.chromium.org/developers/npapi-deprecation

                Oracle are not providing an alternative interface for Java and recommend users use a browser that does support NPAPI.

                Impact to IBM Web Content Manager 8.5 customers


                Customers using Chrome will not be able to use Ephox EditLive! from September onwards. It is possible to re-enable the Java plugin in Chrome before then. See the resolution section for instructions.

                Impact to users of IBM Web Content Manager 8.0.0.1 and earlier


                Customers using Chrome will not be able to use Ephox EditLive from September onwards.

                Additionally, the import function of rich text fields, which is used to import an HTML file and it's images from the local workstation, will no longer function on Chrome regardless of the editor used. This is applicable to all design and markup fields, including rich text elements and components as well as menu and navigator designs. A fix for this is in development and will be available for WebSphere Portal 8.0.0.1 as an iFix and in a cumulative fix (CF) when complete. This fix will not be available on versions earlier than 8.0.0.1.


                  Setup IBM Traveler for IBM Verse App from Zero to Verse Hero

                  Kenio Carvalho  1 May 2015 21:42:33
                  I follow the steps bellow to setup my IBM Traveler 9.0.1.4 to allow the IBM Verse App.

                  My Domino and Traveler is on the same machine using Linux.

                  1 - Install or upgrade the Domino server 9.0.1 FP3

                  2 - Install or upgrade IBM Traveler 9.0.1.4

                  3 - Configure Domino HTTP for SSL.  This link was very useful for self cert.

                  4 - I am using iPhone. The easiest way to import the self cert was sending the cert by mail and then install the cert on the iPhone.

                  5 - Upgrade the Domino Directory ( http://www-01.ibm.com/support/docview.wss?uid=swg21699618). The current Domino Directory Template does not have a tab for IBM Verse.

                  6 - Download the IBM Verse App from the store and be happy :-)
