Linux

To upgrade an existing Fusion installation on Linux:

Place the fusion-4.2.6-service-pack-patch.jar and fusion-4.2.6-sp3.tar.gz on each server hosting Fusion services.
The script does not update external Solr and Zookeeper installations.
Shut down all Fusion services on each server that will receive the patched upgrade.
Run the fusion-4.2.6-service-pack-patch.jar jar (java -jar fusion-4.2.6-service-pack-patch.jar) and follow the prompts.
Start the Fusion services.

Windows

To upgrade an existing Fusion installation on Windows:

Place the fusion-4.2.6-service-pack-patch.jar and fusion-4.2.6-sp3.zip on each server hosting Fusion services. The script does not update external Solr and Zookeeper installations.
Shut down all Fusion services on each server that will receive the patched upgrade.
Run the fusion-4.2.6-service-pack-patch.jar jar (java -jar fusion-4.2.6-service-pack-patch.jar) and follow the prompts.

Enable the Tika parser service

Fusion 4.2.6 SPs include an asynchronous Tika parser service. This service is not automatically enabled upon upgrading. To enable the Tika parser service:

Open fusion/conf/fusion.properties in a text editor.

Add the following Tika entry to the end of the file.

# Tika parser service
tika-server.port = 8889

# If your tika server is properly secured behind a firewall, then you can then set the
# -Dtika.server.allowLocalFileOptimization=true to allow you to use the "local file optimization" which reduces
# http overhead during local tika parses.
tika-server.jvmOptions = -Dtika.MAX_HEAP_MB=1000 -Dtika.NUM_PROCESSES=2 -Dtika.ALLOW_LOCAL_FILE_OPTIMIZATION=true

In the log-shipper section of the file, add the following in a new line:
```
log-shipper.logs.tika-server = java
```
Save the file.
Download the tika-server-log4j2.xml file.
Add the TikaServer logging configuration to the fusion/conf directory.

To automatically start the Tika parser service when starting Fusion, add tika-server to the group.default line. Otherwise, you can start the Tika parser server with the $fusion/bin/tika-server script.
