java - hibernate cached query not updated when new record inserted -

-

we have ehcache cluster, hibernate , mysql.

everything working fine. criteria searches being cached , when records modified on other members of clusters cached queries updated instantly on other servers.

however, problem when new records inserted. cached queries on table not know until cached query expired.

i have missed on ehcache.xml configuration, have no idea be.

any ideas?

ehcache.xml follows:

`

<!--<diskstore path="java.io.tmpdir"/>-->  <!-- means cache replication -->  <cachemanagerpeerproviderfactory     class="net.sf.ehcache.distribution.jgroups.jgroupscachemanagerpeerproviderfactory"     properties="connect=         tcp(bind_port=10700):         s3_ping(...):         merge2(max_interval=30000;min_interval=10000):         fd_sock(start_port=0):         fd(timeout=3000;max_tries=3):         verify_suspect(timeout=1500):         barrier():         pbcast.nakack(use_mcast_xmit=false;gc_lag=0;retransmit_timeout=300,600,1200,2400,4800;discard_delivered_msgs=true):         unicast(timeout=300,600,1200):         pbcast.stable(stability_delay=1000;desired_avg_gossip=50000;max_bytes=400k):         pbcast.gms(print_local_addr=true;join_timeout=300;view_bundling=true):         fc(max_credits=2m;min_threshold=0.10):         frag2(frag_size=60k):         pbcast.streaming_state_transfer()"     propertyseparator="::" />      <!-- default query cache used queries without explicit cache -->  <cache     name="org.hibernate.cache.standardquerycache"     maxelementsinmemory="100"     eternal="false"     timetoliveseconds="600"     overflowtodisk="false"     statistics="true">     <cacheeventlistenerfactory         class="net.sf.ehcache.distribution.jgroups.jgroupscachereplicatorfactory"         properties="replicateasynchronously=true, replicateputs=true,         replicateupdates=true, replicateupdatesviacopy=false, replicateremovals=true" /> </cache>      <!-- timestamps of particular last update time tables -->  <cache     name="org.hibernate.cache.updatetimestampscache"     maxelementsinmemory="5000"     eternal="true"     overflowtodisk="false"     statistics="true">     <cacheeventlistenerfactory         class="net.sf.ehcache.distribution.jgroups.jgroupscachereplicatorfactory"         properties="replicateasynchronously=true, replicateputs=true,         replicateupdates=true, replicateupdatesviacopy=false, replicateremovals=true" /> </cache>  <!-- default cache use cacheable entities without explicit cache -->  <defaultcache         maxelementsinmemory="10000"         eternal="false"         timetoidleseconds="600"         timetoliveseconds="600"         overflowtodisk="false"         maxelementsondisk="10000000"         diskpersistent="false"         diskexpirythreadintervalseconds="600"         memorystoreevictionpolicy="lru"         statistics="true">         <cacheeventlistenerfactory             class="net.sf.ehcache.distribution.jgroups.jgroupscachereplicatorfactory"             properties="replicateasynchronously=true, replicateputs=true,             replicateupdates=true, replicateupdatesviacopy=false, replicateremovals=true" /> </defaultcache>

i'm afraid it's little late author, thought answer can useful else same problem.

you should remember how standardquerycache , updatetimestampscache work. when query cache checked query, time query cached compared timestamps of last update of tables in query. if tables updated after query cached, cached result gets discarded , database used instead. timestamps of last update each table stored in updatetimestampscache.

in above configuration values updatetimestampscache not copied other members of cluster, hibernate looks @ old timestamps , thinks cached query up-to-date. result newly inserted records neglected. fix set replicateupdatesviacopy updatetimestampscache true.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
