Replacing the existing open source Java Azul Zulu JRE installation with another / newer Java Azul Zulu JRE version
To install the migRaven.24/7 we always deliver a Java based Neo4j graph database.
Neo4j strongly recommends using the Java Azul Zulu JRE.
Upgrading the existing Java Azul Zulu JRE installation:
Java Azul Zulu JRE runs on the migRaven.24/7 server needed for the Neo4j database.
Updating the Java version without registering the Windows service again leads to malfunctions.
In this case, the migRavenDB - aikuxGraph service can no longer be started.
Please proceed in the order below:
Verify your currently installed Java version in the Windows command prompt by running the command line.
Java -version
Complete the below migRaven.24/7 services in the order presented.
1. migRavenResource Scan Service Host
2. migRavenADScanServiceHost
3. migRavenCore Service Host
4. migRavenDBServiceHost
5. migRavenDB – aikuxGraph (up to incl. migRaven.24/7 of version 7.2.22207.1)
5a. Neo4j Graph Database – migRavenGraphDB (from incl. migRaven.24/7 of version 7.2.22271.1)
Uninstall the migRavenDB – aikuxGraph service by running the following command line in the Windows command prompt:
