Installation Prerequisites
java -version
Note:
Oracle NoSQL Database is compatible with Java SE 11 (64 bit) or later versions. It is tested and certified against Oracle Java SE 17 (64 bit). It is recommended that you upgrade your systems to the latest Java releases to take advantage of all bug fixes and performance improvements. See Release Notes - Overview for more details on Java requirements.Linux is the officially supported platform for Oracle NoSQL Database. Running the Oracle NoSQL Database requires a 64-bit JVM. You do not
necessarily need root access on each Storage Node for the installation process. Be sure
that the jps
tool is working. Installing the JDK makes the
jps
tool available for use by the Storage Node Agent
(SNA). The jps
tool can be used to verify the Oracle NoSQL
Database processes that are currently running in your Storage Node.

16216 Jps
Note:
You must run the command listed above as the same OS user who will run the Oracle NoSQL Database SNA processes.Finally, make sure that each of the Storage Nodes is running some sort of reliable clock
synchronization. Clock synchronization is necessary for timestamp continuity and
synchronized coordination between storage nodes. Generally, a synchronization delta of
less than half a second is required. Network Time Protocol (ntp)
is
sufficient for this purpose.
