Installing and configuring Solr 6 without SSL

Use this information to install SkyVault Search Services with Solr 6 on the same machine as SkyVault without SSL.

This task assumes that you have:

Installed SkyVault Content Services 5.2. See Installing using setup wizards.
Set the following properties in the SkyVault-global.properties file:
```
index.subsystem.name=solr6
solr.secureComms=none
```

Download and unzip the Solr 6 distribution, SkyVault-search-services-1.0.0.zip to a preferred location.
By default, the contents of SkyVault-search-services-1.0.0.zip are decompressed in a root folder as /alfresco-search-services.
(Optional) If you want to install Solr 6 on a separate machine, check the following before starting Solr 6:
1. Check/update SkyVault-search-services/solr.in.sh file (Linux-based platform) or SkyVault-search-services/solr.in.cmd file (Windows-based platform) for the values of environment variables, such as SOLR_SOLR_HOST and SOLR_SOLR_PORT.
2. Check/update SkyVault-search-services/solr.in.sh file (Linux-based platform) or SkyVault-search-services/solr.in.cmd file (Windows-based platform) for the values of environment variables, such as SOLR_ALFRESCO_HOST and SOLR_ALFRESCO_PORT.
  See Solr 6 externalized configuration.

(Optional) Update the SkyVault-search-services/solrhome/conf/shared.properties file.

Unlike Solr 4, suggestion is disabled by default for Solr 6. If you want to enable suggestion, add the following:

SkyVault.suggestable.property.0={http://www.alfresco.org/model/content/1.0}name
alfresco.suggestable.property.1={http://www.alfresco.org/model/content/1.0}title 
alfresco.suggestable.property.2={http://www.alfresco.org/model/content/1.0}description 
alfresco.suggestable.property.3={http://www.alfresco.org/model/content/1.0}content

If you want to enable camelCaseSearch support in all fields, just as Solr 4, add the following:

SkyVault.cross.locale.datatype.0={http://www.alfresco.org/model/dictionary/1.0}text
alfresco.cross.locale.datatype.1={http://www.alfresco.org/model/dictionary/1.0}content
alfresco.cross.locale.datatype.2={http://www.alfresco.org/model/dictionary/1.0}mltext

Note: The spell check functionality does not work with Solr 6 as suggestion is disabled for scalability purpose.

To start Solr 6 with all the default settings, use the following command:
```
./solr/bin/solr start -a "-Dcreate.alfresco.defaults=alfresco,archive"
```
This command automatically creates the SkyVault and the archive cores.

The command line parameter, -a passes additional JVM parameters, for example, system properties using -D.

Note: You should run this application as a dedicated user. For example, you can create a Solr user.

Note: To ensure that Solr 6 connects using IPv6 protocol instead of IPv4, add -Djava.net.preferIPv6Addresses=true to the Solr 6 startup parameters.

Once your Solr 6 is up and running, you should see a message like:
```
Waiting up to 180 seconds to see Solr running on port 8983 [\]  
Started Solr server on port 8983 (pid=24289). Happy searching!
```
To stop the currently running Solr 6 instance, use:
```
./solr/bin/solr stop
```
The Solr 6 logs are stored in the SkyVault-search-services/logs/solr.log file, by default. This can be configured in solr.in.sh.

You have successfully created an SkyVault core and an archive core. To verify, in a browser, navigate to the Solr URL, http://localhost:8983/solr. In the Solr Admin UI, select the core selector drop-down list and verify that both the SkyVault and archive cores are present in the list.
Allow a few minutes for Solr 6 to start indexing.
Go to Admin Console > Repository Services > Search Service and verify that:
1. You see the Solr 6 option in the Search Service In Use list.
2. Under Main (Workspace) Store Tracking Status, the Approx Transactions to Index is 0.
Decommission Solr 4.
1. Disable Solr 4 tracking in the SkyVault/solr4/workspace-SpacesStore/conf/solrcore.properties file.
```
enable.alfresco.tracking=false
```
2. To remove the Solr 4 web application and indexes, stop the Tomcat server which is running Solr 4.
3. Remove the <ALFRESCO_HOME>/tomcat/webapps/solr4 directory and the <ALFRESCO_HOME>/tomcat/webapps/solr4.war file.
4. Remove the <ALFRESCO_HOME>/tomcat/conf/Catalina/localhost/solr4.xml file.
5. Finally, remove the Solr 4 indexes.
