Hi, We configured ElasticSearch with Oracle CMS(WCC 12c) for a Single Node Elasticsearch on Linux. and migrated ~4 Million contents to this newer CMS. The configurations seems correct and username is set however noticed below errors in logs. We are also facing issues running the Full collection rebuild for indexing. So, if it is the same issue that is causing this? esConnStrings -\> :; username -\> null; certPath -\> es01.p12 java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.elasticsearch.client.RestClient.(RestClient.java:99) at intradoc.elasticsearch.client.ElasticSearchConnectionClient.initSecureElasticSearchRestClient(ElasticSearchConnectionClient.java:246) at intradoc.elasticsearch.client.ElasticSearchConnectionClient.init(ElasticSearchConnectionClient.java:118) at intradoc.elasticsearch.indexer.ElasticSearchCollectionHandler.validateConfiguration(ElasticSearchCollectionHandler.java:751) at intradoc.server.SearchLoader.refreshCollectionData(SearchLoader.java:799) at intradoc.server.subject.DynamicQueriesSubjectCallback.checkSearchIndexDesign(DynamicQueriesSubjectCallback.java:418) at intradoc.server.subject.DynamicQueriesSubjectCallback.refresh(DynamicQueriesSubjectCallback.java:53) at intradoc.server.IdcSystemLoader.loadCachedTables(IdcSystemLoader.java:1501) at intradoc.server.IdcSystemLoader.loadCaches(IdcSystemLoader.java:1333) at intradoc.apps.shared.StandAloneApp.finishLoad(StandAloneApp.java:345) at intradoc.apps.shared.StandAloneApp.initSystem(StandAloneApp.java:282) at intradoc.apps.shared.StandAloneApp.init(StandAloneApp.java:113) at intradoc.apps.shared.AppLauncher.init(AppLauncher.java:253) at IdcAnalyze.main(IdcAnalyze.java:67) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at intradoc.loader.IdcClassLoader.invokeMain(IdcClassLoader.java:392) at intradoc.loader.IdcClassLoader.startMain(IdcClassLoader.java:187) at intradoc.loader.IdcClassLoader.main(IdcClassLoader.java:152) Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory ---

Thanks. This error comes when trying to run IdcAnalyzer which is a WebCenter Content (WCC) Tool used to Check if the Database, File System, and Index are all in Sync. We running this tool since we are getting another error while Full collection rebuild for Indexing . I earlier noted that the cert es01.p12 mentioned was of 0 bytes before and i replaced it the correct certificate. Is their a way to check if there any issues with the certificate ---

Sorry but we don't support that tool ourselves, and given that error is coming from there it's nothing that we can help with unless there is an actual Elasticsearch error reported somewhere. ---
