Checking the agent prerequisites on UNIX
Before you install the agent, make sure that all the necessary prerequisites are met. See the following sections for supported operating systems and platform architectures and other necessary prerequisites:
Supported operating systems and platform architectures
The following table shows the operating systems, versions, and architectures that are supported by the Instana agent on UNIX:
OS | Version | Architecture | Bitness |
---|---|---|---|
AIX [1] | 7.x | PowerPC | 32 bit |
AIX [1:1] | 7.x | PowerPC | 64 bit |
Solaris | 10+ | SPARC | 32 bit |
Solaris | 10+ | SPARC | 64 bit |
Prerequisites
The Instana host agent requires a Java Software Development Kit (Java SDK) installed on the host. You can set up the Java SDK for the host agent in two ways:
-
Place or link the Java SDK into the
<instana-agent-dir>/jvm
folder so that the location<instana-agent-dir>/jvm/bin/java
is created. -
Export an environment variable called
JAVA_HOME
to point to the Java SDK. You can also set this environment variable by adding it to the<instana-agent-dir>/bin/setenv
file.
The Instana agent supports the following Java SDKs:
- IBM OpenJ9 JDK 11 (Preferred)
- Azul Zulu JDK 11 (Preferred on Solaris SPARC)
- Oracle Hotspot JDK 11
- IBM J9 11
- OpenJDK 11
- AdoptOpenJDK 11
- Amazon Corretto JDK 11
Ensure that the Java Virtual Machine (JVM) can be used by any user on the system. Use the latest available patch release of the Java distribution of your choice. The host agent requires a Java SDK that supports TLSv1.3 (available in all current
Java SDK 8 and Java SDK 11 builds). If you use a Java SDK package that does not support strong encryption, you might get errors such as java.lang.RuntimeException: Could not generate DH key pair
