Control-Flow Statement into "action nodes" (RULEFLOW)
-----------------------------------------------------
Key: JBRULES-1403
URL: http://jira.jboss.com/jira/browse/JBRULES-1403
Project: JBoss Drools
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Eclipse IDE
Affects Versions: 4.0.3
Environment: Eclipse Europa 3.3.1.1
Reporter: Massimiliano Magistri
I tried to add the following (stupid) statement into the action node "textual editor":
if (true) int i=0;
and I got back an exception as follows:
org.mvel.PropertyAccessException: unable to resolve property: if ( true )

[JBoss JIRA] Updated: (JBAS-1436) Improved management
by Vicky Kak (JIRA)
[ http://jira.jboss.com/jira/browse/JBAS-1436?page=all ]
Vicky Kak updated JBAS-1436:
----------------------------
Fix Version/s: (was: JBossAS-4.2.3.GA)
> Improved management
> -------------------
>
> Key: JBAS-1436
> URL: http://jira.jboss.com/jira/browse/JBAS-1436
> Project: JBoss Application Server
> Issue Type: Task
> Security Level: Public(Everyone can see)
> Components: JCA service
> Reporter: Adrian Brock
> Assigned To: Vicky Kak
> Priority: Minor
> Fix For: JBossAS-5.1.0.CR1

>
> Forum Discussion Thread: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=48682
> **This is a holder issue. Each section should be raised as a new issue as it is
> developed with a link from this issue.**
> There are a number of areas in JCA that need better management capabilities.
> Some of these stats may also reveal the need for new configuration/tuning parameters.
> In core JCA:
> 1) Better visibility on the ManagedConnectionFactory.
> This is currently a DynamicMBean that provides basic config parameters, but we could also
> provide a proxy/wrapper to provide statistics of operations on the factory and its
> ManagedConnections.
> a) createManagedConnections
> b) matchManagedConnections
> c) events on from the listeners
> 2) Better visibility of the Pool(s)
> Only top level statistics are provided (you cannot see the subpools).
> The statistics are also not synchronized with the pool (for performance reasons
> and also the fact that each stat is retrieved on individual MBean getAttribute requests)
> Additional statistics could include wait times when requests are waiting on an empty pool,
> idle time of unused connections, etc.
> 3) Better visibility of the ConnectionManager
> Currently this has no visibility for management.
> Its main responsibilties are transactions enlistment and security.
> e.g. This could show how long is wasted because <track-connection-by-tx/> does not
> return the connection the pool until transaction completion.
> 4) JDBC resource adapter
> PreparedStatementCache stats
> Query time stats
> etc.
> 5) JMS resource adapter
> Message send/receive stats
> 6) Inbound messaging
> Stats for message delivery
> 7) Transaction inflow
> Stats for transaction inflow and also display a list of current inbound transactions
> 8) Work management
> Stats for the work management pools and timers
