      IBM XPages DatabaseName URL Parameter Whitelist

      Kenio Carvalho  12 August 2015 18:32:23
      In IBM Notes/Domino 9.0.1 FixPack 4 and in releases containing the fix for SPR#MKEE9TKDEM, you may see an error page with the following error message:

      CLFAD0382E: The databaseName URL parameter value is not one of the allowed database names. The parameter is &databaseName=otherserver!!app.nsf.

      The allowed names are configured in the option xsp.data.domino.param.databaseName.whitelist.
      There has been a change in the XPages default behavior, that now requires that the allowable databaseNames be configured in a whitelist. The white list is an option that lists allowed databaseNames. Where the whitelist has not been configured, the error above will occur for remote applications (i.e., applications that are not on the current server). There is an option to revert to the previous behavior but there are security implications associated with that decision.

        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

              Multiple vulnerabilities in IBM Java 6 SR16FP3 IF1 affect IBM Notes and Domino

              Kenio Carvalho  3 June 2015 17:34:49
              There are multiple vulnerabilities in IBM® SDK Java™ Technology Edition, Version 6 SR16FP3 IF1 that is used by IBM Notes and Domino. These issues were disclosed as part of the Oracle April 2015 Critical Patch Update and are resolved by IBM Java 6 SR16FP3 IF2.

                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
