Hi all, I've been trying the SRW module (http://code.google.com/p/oclcsrwdspacelucene/) with dspace 1.7 and i've being facing a problem when I repetitively make the same query:
http://10.0.102.1:8080/SRW/search/?query=dc.creator+%3D+%22smith%22&version=1.1&operation=searchRetrieve&recordSchema=info%3Asrw%2Fschema%2F1%2Fdc-v1.1&maximumRecords=10&startRecord=1&resultSetTTL=300&recordPacking=xml&recordXPath=&sortKeys= i will get: 404: Document not found (No searchRetrieveResponse) OCLC SRW/SRU Server after 3 minutes or so it will restart working. With some extra debugging (thanks to Ralph): ORG.oclc.os.SRW.HouseKeeping=DEBUG ORG.oclc.os.SRW.DSpaceLucene.LuceneQueryResult=DEBUG log4j.logger.ORG.oclc.os.SRW.HouseKeeping=DEBUG log4j.logger.ORG.oclc.os.SRW.DSpaceLucene.LuceneQueryResult=DEBUG i will get the following exception in dspace.cfg: 2011-03-10 16:15:33,978 DEBUG ORG.oclc.os.SRW.SRWServlet @ exit processMethodRequest 2011-03-10 16:15:33,978 DEBUG ORG.oclc.os.SRW.SRWServlet @ Exit: doGet() 2011-03-10 16:15:34,318 ERROR ORG.oclc.os.SRW.DSpaceLucene.SRWLuceneDatabase @ java.lang.InstantiationException: Cannot get a connection, pool error Timeout waiting for idle object java.lang.InstantiationException: Cannot get a connection, pool error Timeout waiting for idle object at ORG.oclc.os.SRW.DSpaceLucene.LuceneQueryResult.<init>(LuceneQueryResult.java:113) at ORG.oclc.os.SRW.DSpaceLucene.SRWLuceneDatabase.getQueryResult(SRWLuceneDatabase.java:209) at ORG.oclc.os.SRW.SRWDatabase.doRequest(SRWDatabase.java:598) at gov.loc.www.zing.srw.srw_bindings.SRWSoapBindingImpl.searchRetrieveOperation(SRWSoapBindingImpl.java:138) at gov.loc.www.zing.srw.srw_bindings.SRWSoapBindingSkeleton.searchRetrieveOperation(SRWSoapBindingSkeleton.java:68) at sun.reflect.GeneratedMethodAccessor71.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.axis.providers.java.RPCProvider.invokeMethod(RPCProvider.java:397) at org.apache.axis.providers.java.RPCProvider.processMessage(RPCProvider.java:186) at org.apache.axis.providers.java.JavaProvider.invoke(JavaProvider.java:323) i've been suggested to try with resultSetTTL=0 in the URL and the configuration, but i didn't see any improvements, does anybody faced/resolved the same issue? thanks Kocisky ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ DSpace-tech mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/dspace-tech
