portal load test: optimize DB query ----------------------------------- Key: JBPORTAL-1211 URL: http://jira.jboss.com/jira/browse/JBPORTAL-1211 Project: JBoss Portal Issue Type: Bug Security Level: Public(Everyone can see) Components: Portal Core Affects Versions: 2.4.1 SP1 Reporter: Prabhat Jha Assigned To: Julien Viet During portal load test, we found some bottlenecks related to call to DB. At 500 simultaneous user thread, we start seeing org.jboss.util.NestedSQLException: No ManagedConnections available within configured blocking timeout with min pool size of 20 and max pool size of 40. I am not sure but the following query which does join of 6 tables probably also needs to be optimized select portalobje0_.PK as PK20_0_, portalobje0_.LISTENER as LISTENER20_0_, portalobje0_4_.INSTANCE_REF as INSTANCE2_27_0_, case when portalobje0_1_.PK is not null then 1 when portalobje0_2_.PK is not null then 2 when portalobje0_3_.PK is not null then 3 when portalobje0_4_.PK is not null then 4 when portalobje0_.PK is not null then 0 end as clazz_0_, declaredpr1_.OBJECT_KEY as OBJECT1_2_, declaredpr1_.jbp_VALUE as jbp2_2_, declaredpr1_.NAME as NAME2_, modes2_.PK as PK3_, modes2_.name as name3_, windowstat3_.PK as PK4_, windowstat3_.name as name4_ from JBP_PORTAL_OBJECT portalobje0_ left outer join JBP_CONTEXT portalobje0_1_ on portalobje0_.PK=portalobje0_1_.PK left outer join JBP_PORTAL portalobje0_2_ on portalobje0_.PK=portalobje0_2_.PK left outer join JBP_PAGE portalobje0_3_ on portalobje0_.PK=portalobje0_3_.PK left outer join JBP_WINDOW portalobje0_4_ on portalobje0_.PK=portalobje0_4_.PK left outer join JBP_PORTAL_OBJECT_PROPS declaredpr1_ on portalobje0_.PK=declaredpr1_.OBJECT_KEY left outer join JBP_PORTAL_MODE modes2_ on portalobje0_.PK=modes2_.PK left outer join JBP_PORTAL_WINDOW_STATE windowstat3_ on portalobje0_.PK=windowstat3_.PK where portalobje0_.PK=?
