How I can raise this two variables: maxUpdateConnections,

One way to handle this is the shardHandlerFactory setting in 
solrconfig.xml.  I think you'd need it on the /update handler and any 
other handlers you want to modify.  I don't think I'd do it this way ... 
solr.xml lets you set these values globally.

http://wiki.apache.org/solr/SolrConfigXml#Configuration_of_Shard_Handlers_for_Distributed_searches

Looking at the code for handling the old style solr.xml, it looks like 
you can set these as parameters on the <cores> tag, which is inside the 
<solr> tag.  Here's the code:

    storeConfigPropertyAsInt(CfgProp.SOLR_MAXUPDATECONNECTIONS, 
"solr/cores/@maxUpdateConnections");
storeConfigPropertyAsInt(CfgProp.SOLR_MAXUPDATECONNECTIONSPERHOST, 
"solr/cores/@maxUpdateConnectionsPerHost");

Code in another place sets the default values if these are not present, 
which are 10000 for maxUpdateConnections and 00 for 
maxUpdateConnectionsPerHost.

  public int getMaxUpdateConnections() {
    return get(CfgProp.SOLR_MAXUPDATECONNECTIONS, 10000);
  }

  public int getMaxUpdateConnectionsPerHost() {
    return get(CfgProp.SOLR_MAXUPDATECONNECTIONSPERHOST, 100);
  }

Thanks,
