remove does not remove node when using optimistic locking and called on an instance which does not contain the node. -------------------------------------------------------------------------------------------------------------------- Key: JBCACHE-1545 URL: https://jira.jboss.org/jira/browse/JBCACHE-1545 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Replication Affects Versions: 1.4.1.SP13 Reporter: Dennis Reed Assignee: Manik Surtani With optimistic locking, remove ( String fqn ), and remove ( String fgn, Object key ) do not remove from other cluster members if the node does not exist in the local cache. This can happen when using invalidation, or when the node has been evicted. -- 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: (JBCACHE-1577) Cannot clear a distributed cache locally

by Nicolas Filotto (JIRA)

Cannot clear a distributed cache locally ---------------------------------------- Key: JBCACHE-1577 URL: https://jira.jboss.org/jira/browse/JBCACHE-1577 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 3.2.3.CR1 Reporter: Nicolas Filotto Assignee: Manik Surtani Attachments: removeNodeFix.diff I have a distributed cache and I would like to be able to clear it locally so I used the following code: {code} cache.getInvocationContext().getOptionOverrides().setCacheModeLocal(true); cache.removeNode(Fqn.ROOT); {code} Unfortunatelly, all the nodes are removed in all the cache instances in my cluster. After a deeper investigation, it seems to be a bug in CacheInvocationDelegate.removeNode that doesn't properly set the option overrides since it reuse the same option object that is reset after each call. I attached a unit test and a patch for this bug. -- 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: (JBCACHE-1565) Locking doesn't work when replication is used

Locking doesn't work when replication is used --------------------------------------------- Key: JBCACHE-1565 URL: https://jira.jboss.org/jira/browse/JBCACHE-1565 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 3.2.1.GA Environment: Linux, Sun Java 5.0 Reporter: tbech Assignee: Manik Surtani Priority: Critical Attachments: exc.txt During performance tests of JBossCache, I've tried to test transactions with cache.getInvocationContext().getOptionOverrides().setForceWriteLock operation ('select-for-update'). I've used standard jbosscache benchmark from svn. I've created new product jbosscache3.2.1 based on 3.1.0 and new test. Basicaly it did: try { long startTime = System.nanoTime(); if (concurrentWrites) { cacheWrapper.startTransaction(); cacheWrapper.setForceWriteLock(true); } ObjectInCache o = (ObjectInCache) cacheWrapper.get(path, key); o = new ObjectInCache(Integer.valueOf(o.getVal().intValue() + 1), randStr[taskNumber%randStr.length]); cacheWrapper.put(path, key, o); if (concurrentWrites) { cacheWrapper.endTransaction(true); } long statValue = (System.nanoTime() - startTime); descriptiveStatistics.addValue(statValue); } catch (Throwable e) { log.error("Error appeared whilst writing to cache:" + e.getMessage(), e); try { if (concurrentWrites) { cacheWrapper.endTransaction(false); } } finally { } } finally { logRunCount(taskNumber); } concurrentWrites was set to true. This tests passes nicely in one node (local mode). However in 2,3,4 nodes it fails after first usage of the same object by different node with exception: org.jboss.cache.lock.TimeoutException: Unable to acquire lock on Fqn [/concurrent/Intermediate-0/Node 0] after [240000] milliseconds for requestor [GlobalTransaction:<10.118.236.212:40325>:0]! Lock held by [GlobalTransaction:<10.118.236.211:8112>:40] at org.jboss.cache.mvcc.MVCCNodeHelper.acquireLock(MVCCNodeHelper.java:159) It looks like, in replication the node is not beeing releases after transaction commit. -- 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
