The following steps are required only for SAS Visual Investigator 10.8 releases from Hot Fix 6 onwards.

For SAS Visual Investigator 10.8 releases before Hot Fix 6, refer to SAS Note 69756, "Updating the Java Development Kit (JDK) instructions for Elasticsearch with SAS^® Visual Investigator 10.8.”

To update the JDK, complete the following steps:

1. For SAS Visual Investigator 10.8 only, Java 11 is a prerequisite to support OpenSearch 1.3. That OpenSearch distribution is not used by other SAS^® Viya^® 3.5 products. The Java 11 requirement applies only to OpenSearch and not to SAS^® Visual Investigator. 

To ensure that the Java version is supported by OpenSearch, see the following link: https://opensearch.org/docs/1.3/install-and-configure/install-opensearch/index/#java-compatibility.

2. Note the path to JDK 11 installation. You can verify the JDK 11 path by running a command similar to the following:

Note: You should perform steps #3 and #4 on all the nodes in the OpenSearch cluster.

3. Set the OPENSEARCH_JAVA_HOME variable to the installation directory of Java 11.

1. Do the following for a new deployment:  

1. Create a file called sas-viya-svi-elasticsearch-default.service.conf within the /etc/systemd/system/sas-viya-svi-elasticsearch-default.service.d directory.
2. Populate the file with the following:

3. Run this command to apply the changes:

2. Do the following for an existing deployment: 
   1. ​​​​Back up and edit the /opt/sas/viya/config/etc/sysconfig/sas-svi-elasticsearch/default/sas-svi-elasticsearch file.
   2. Then, add the following line:

4. Restart the sas-viya-svi-elasticsearch-default service on all the nodes in the cluster, if applicable.

5. Check the /opt/sas/viya/config/var/log/svi-elasticsearch/sas-opensearch.log file for any errors. You can also verify whether the JDK 11 path is used by reviewing the sas-opensearch.log file, as shown in the example below:
