[jira] Commented: (TUSCANY-1997) Axis binding does not allow external configuration to increase the number of the maximum connections opened.

["Jean-Sebastien Delfino (JIRA)" <tu...@ws.apache.org>]

    [ https://issues.apache.org/jira/browse/TUSCANY-1997?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12570553#action_12570553 ] 

Jean-Sebastien Delfino commented on TUSCANY-1997:
-------------------------------------------------

Using a custom HTTP connection manager with a bigger connection pool per host solves the problem, but we need a clean mechanism to allow a system administrator to provide that kind of policy configuration, on a reference and binding basis, without requiring custom policy intents or changes to the logical composition.

Here are the steps that I think we need to perform to provide that capability:

1. Support multiple definitions.xml files in an SCA domain (done by Venkata).

2. Implement proper handling of PolicySet appliesTo attributes with xpath expression matching against composite elements (recently done by Venkata).

3. Support the ability to externally attach PolicySets to composite elements. I've proposed a simple interim solution for this until the OpenCSA policy spec workgroup defines a more general policy attachment mechanism in [1].

4. Define a Tuscany-specific PolicySet for configuring the Axis2 HTTP connection pool.

(1) and (2) are done, I think we should target (3) and (4) for release 1.2.

> In a high volume situation the default setting for Axis2 is 2 connections per host.
> The default protocol being HTTP 1.1 , this means that only 2 POST requests can be issued at the same time.
