lucene - RCA needs more information, using Hibernate Search -


one of our customers, whom did custom development facing weird issue. though still in pre-uat, see not conforming known lucene behavior.

we using hibernate search 5.5.2, apache lucene 5.3.x; using filesystem index. running inside weblogic 12c container, oracle 12c database.

we have 2 different virtual machines host 2 different weblogic 12c instances (thereby application) point same database (thereby same data); @ start of application, index data on filesystem on each of nodes. same query, yields different results on each of nodes!

has faced similar issue? indexing mechanism in way tied hardware or specific machine? cannot fathom reason behavior.

also, next question if there non-replicated (no form of replication) clustered nodes (weblogic 12c) - ok index on each of nodes separately,the same data? or necessary use master-slave replication? not need answer maintainability point of view, rather view of correctness of results?

see original question on official hibernate search forum at: https://forum.hibernate.org/viewtopic.php?f=9&t=1043314

it appears if store index on each node containing data modified through node. query results vary depending on node executing query.

you should options clustered set-ups, master/slave set-up using jms or infinispan-based backend. both make sure there single index containing data.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
