Resource change scanner and notifier in drools-server don't start ----------------------------------------------------------------- Key: JBRULES-2947 URL: https://issues.jboss.org/browse/JBRULES-2947 Project: Drools Issue Type: Enhancement Security Level: Public (Everyone can see) Affects Versions: 5.2.0.M1, 5.1.1.FINAL, 5.1.0.FINAL Reporter: Robert Gibbon Assignee: Mark Proctor Please see these offsite links for a detailed explanation of the issue and possible resolution actions: http://drools.46999.n3.nabble.com/Starting-resource-change-scanner-and-no... http://drools.46999.n3.nabble.com/drools-server-resource-change-scanner-n... Basically the execution-server isn't polling Guvnor-server for changes to rule resources...only way to trigger a refresh is to touch the deployment descriptor - which is a dirty hack && takes the service down for a few moments. It would be fantastic to get this implemented in the otherwise excellent execution server 5.2 TIA!! -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (JBAS-8824) Cardinality constraints on children are not enforced after parsing

by Brian Stansberry (JIRA)

Cardinality constraints on children are not enforced after parsing ------------------------------------------------------------------ Key: JBAS-8824 URL: https://issues.jboss.org/browse/JBAS-8824 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: Domain Management Affects Versions: 7.0.0.Alpha1 Reporter: Brian Stansberry Priority: Critical Fix For: 7.0.0.Beta1 The parsers enforce cardinality constraints on child elements in the model, but they aren't enforced thereafter. So, for example, a second "profile" or "socket-binding-group" could be added to a standalone server via a management operation. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JGRP-1317) STABLE: compress STABLE messages

by Bela Ban (JIRA)

STABLE: compress STABLE messages -------------------------------- Key: JGRP-1317 URL: https://issues.jboss.org/browse/JGRP-1317 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.12.2, 3.1 For large clusters, stable messages are quite large, and should be compressed. E.g.: - Don't send the entire view (with all members), but only the ViewId, then the indices of a digest array would point to the rank of a member within the referred-to ViewId - A digest has 3 longs (low, highest_received and highest_delivered). Do we need all 3 every time ? - Compress the 3 longs into 1 long and 2 shorts: the latter 2 are offsets from the first seqno - Use a bit set (consisting of a variable number of ints) to set the 3 variables - If we have a digest (0), 0, 0: send a special marker - Canonicalize digests: if everyone has (14) 20, 22, then we could write it once, give it an ID of (say) 1 and then only refer to 1 again if we encounter the same digest. Actually, as a matter of fact, most of the digests would be the same, so this optimization could have a big effect ! -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (JGRP-1052) Ergonomics

by Bela Ban (JIRA)

Ergonomics ---------- Key: JGRP-1052 URL: https://jira.jboss.org/jira/browse/JGRP-1052 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.0 The goal is to (a) reduce the number of properties needed and (b) determine the values dynamically. Examples: - Determine the best min/max size of a thread pool - Find out what the best timeout values are for retransmission, e.g. based on average retransmission times - Determine the optimal number of credits in FC This is similar to the JVM setting where, starting with 1.5, the initial values can be set, but over time, the JVM dynamically changes them. In the best case, a config contains only a list of protocols without any properties, and JGroups will figure out the correct values. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-2438) loading multiple sheets of single Excel book by one change-set xml

by Toshiya Kobayashi (JIRA)

loading multiple sheets of single Excel book by one change-set xml ------------------------------------------------------------------ Key: JBRULES-2438 URL: https://jira.jboss.org/jira/browse/JBRULES-2438 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Reporter: Toshiya Kobayashi Assignee: Mark Proctor I'm trying to use rules via DecisionTable using change-set. I wrote rules in multiple sheets of single Excel book. Then I configured my change-set xml like: ... <add> <resource source='classpath:data/dtable.xls' type="DTABLE"> <decisiontable-conf input-type="XLS" worksheet-name="sheet1" /> </resource> <resource source='classpath:data/dtable.xls' type="DTABLE"> <decisiontable-conf input-type="XLS" worksheet-name="sheet2" /> </resource> </add> ... But only rules of sheet1 were loaded. As far as I observed source codes, KnowledgeAgentImpl.java puts resource into "Map<Resource, ResourceMapping> resources". But even if multiple resources are configured in change-set, it appears to me like those resources are considered as the same resource and eventually only one resource will be registered. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
