Problems with solr6 index rebuild and alfresco 6.x

[cartif]

Dear support,

My name is Ángel and I am writing to you from Fundación CARTIF. As I indicated in the thread issue, we have problems with the SOLR 6 engine in our Alfresco Community 6.x

Specifically, we saw the following error in the alfresco.log and tried to rebuild the entire solr6 indexing but it didn't work.

2020-06-08 12:10:23,615 ERROR [org.alfresco.repo.site.SiteServiceImpl] [http-nio-8080-exec-23] LuceneQueryParserException with findSites()
org.alfresco.repo.search.impl.lucene.LuceneQueryParserException: 05080032 Request failed 500 /solr/alfresco/afts?wt=json&fl=DBID%2Cscore&rows=5&df=TEXT&start=0&locale=es_ES&alternativeDic=DEFAULT_DICTIONARY&fq=%7B%21afts%7DAUTHORITY_FILTER_FROM_JSON&fq=%7B%21afts%7DTENANT_FILTER_FROM_JSON

The symptoms are as follows:
- When accessing a site's repository a popup appears with the previous error.
- We get different results with different users when we do a document search in the whole repository. Add that after trying a rebuild of the index now no user finds anything.

We have followed these links:
https://docs.alfresco.com/5.1/tasks/solr-reindex.html
https://www.zylk.net/en/web-2-0/blog/-/blogs/performing-a-full-reindex-with-solr-for-alfresco-ecm

Any idea what might be happening and how to fix it?
Thank you very much for your attention.

Best regards,

Ángel.

Hi @angelborroy ,

Thanks for your suggestion. With Java SE11 or Java OpenJDK 11 I get this error on Tomcat logs:

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
NOTE: Picked up JDK_JAVA_OPTIONS:  --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED
-Djava.endorsed.dirs=/opt/alfresco/tomcat/endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.

The only way I can run Alfresco 6.x is with Java version 8.

Thank you.
Best regards,
Ángel.

Sorry, the upload of the log file "solr.log" has failed. It has now been attached.

You are not using Java 11.

[cartif]

Hi,

As I said here, the problem when I use Java 11 is the "endorsed" module. I don't know how to solve that.

Best regards,
Ángel.

[angelborroy]

You could use Java 11 for SOLR and Java 8 for Alfresco Repository.

But Alfresco Repository should be working also with Java 11.

Hi @EddieMay 

Thank you very much for the link! Obviously I just registered for the webinar as it is directly related to this thread.

Best regards,

Ángel.
