  <chapter id="Buildin-HPCC-from-Source">
    <title>Using Configuration Manager</title>

    <para>Configuration Manager is the utility with which we configure the
    HPCC platform. The HPCC platform's configuration is stored in an XML file
    named <emphasis role="bold">environment.xml</emphasis>. When you install a
    package, a default single-node environment.xml is generated. After that,
    you can use the Configuration Manager to modify it and add nodes and
    configure components.</para>

    <para>The Configuration Manager Wizard creates a similar file, but after
    it is generated, you must rename it and put it into place on each
    node.</para>

    <para>Configuration Manager also offers an <emphasis role="bold">Advanced
    View</emphasis> which allows you to add instances of components or change
    the default settings for components. Even if you plane to use Advanced
    View, it is a good idea to start with a wizard generated configuration and
    use Advanced View to finish it.</para>

    <para>This document will guide you through configuring an HPCC environment
    using the Configuration Manager.</para>

      use that environment or experienced users can then use the <emphasis

      There is also the option of using <emphasis role="bold">Create blank
      environment</emphasis> to generate an empty environment that you could
      then go in and add only the components you would want.</para>

          <para>This section describes the Thor Cluster Attributes tab.</para>

          <para>
            <graphic fileref="images/CM-img18-1.jpg" vendor="configmgrSS" />
          </para>

          <para>
            <emphasis role="bold">Thor Memory Settings</emphasis>
          </para>

          <para>If <emphasis role="bold">globalMemorySize</emphasis> is left
          unset, Thor[master] detects total physical memory and allocates 75%
          of it. If there are multiple slaves per node (slavesPerNode&gt;1) it
          divides the total among the slaves. If globalMemorySize is defined,
          then it allocates that amount of memory to each slave. The
          masterMemorySize attribute allocates memory for the Thor master. If
          omitted, Thor master uses globalMemorySize, or the default 75% of
          memory.</para>

          <para>On systems with a lot of memory, the default 75% of physical
          memory is probably too conservative and reserving total physical
          minus 2GB (for the OS and other processes) is sensible. You should
          then divide that number by the number of slavesPerNode.</para>

          <para>If there are multiple Thors sharing the same nodes, then
          globalMemorySize must be configured to take that into
          account.</para>

          <para>For example, if there are 2 Thors each with 2 slaves per box,
          that will mean there are 4 slaves per physical node. So you should
          use a formula similar to the following in your calculations when
          configuring globalMemorySize:</para>

          <programlisting>globalMemorySize = (total-physical-memory)-2GB / (2*2) </programlisting>

          <para>Without any specified setting, Thor assumes it has exclusive
          access to the memory and would therefore use too much (because each
          Thor is unaware of the other's configuration and memory
          usage).</para>

          <para>if <emphasis role="bold">localThor</emphasis> is set to true
          and <emphasis role="bold">masterMemorySize</emphasis> and <emphasis
          role="bold">globalMemorySize</emphasis> are unspecified, then the
          defaults will be 50% for <emphasis
          role="bold">globalMemorySize</emphasis> (divided by <emphasis
          role="bold">slavesPerNode</emphasis>) and 25% for <emphasis
          role="bold">masterMemorySize.</emphasis></para>

          <para>Although a configuration may be set using upper memory limits
          that exceed total physical memory, Thor will not actually reserve
          the memory ahead of time and will only hit memory problems when and
          if your jobs use all of memory. So, for example, two Thors that are
          configured to use all available memory could peacefully co-exist
          until a query on each are simultaneously using more memory than the
          node has available.</para>
