JAVA support in iDRAC
About this task
- Oracle version of Java is supported.
- Java version 8 or later is required.
- If you are using Firefox or Internet Explorer, and want to use the Java viewer to access iDRAC, configure the browser to use Java plug-in.
NOTE:On a 64-bit operating system, both 32-bit and 64-bit JRE versions are supported. On a 32-bit operating system, only 32-bit JRE version is supported.
- On Linux, Java is the default plug-in type for accessing the Virtual Console.
- When the iDRAC firmware is updated, launching Virtual Console with Java plug-in may fail. Delete the Java cache and then launch the Virtual Console.
- When using the Virtual Console, if you face issues such as out-of-range errors, synchronization issues, and so on, clear the browser’s cache to remove or delete any old versions of the viewer that may be stored on the system, and then try again.
NOTE:You must have administrator privilege to clear the browser’s cache.
- To clear older versions of Java viewer in Windows or Linux:
- Using the command prompt, run javaws-viewer or javaws-uninstall. The Java Cache viewer is displayed.
- Delete the items titled iDRAC Virtual Console Client.
- To clear older versions of Java viewer in Windows or Linux:
- If SSL encryption is set to 256-bit or higher and 168-bit or higher, the cryptography settings for your virtual machine environment (JVM, IcedTea) may require installing the Unlimited Strength Java Cryptography Extension Policy Files to permit usage of iDRAC plugins such as Virtual Console with this level of encryption. For information about installing the policy files, see the documentation for Java.
- While launching the Virtual Console using Java plug-in, you may occasionally see a Java compilation error. To resolve this, go to Java control panel > General > Network Settings and select Direct Connection.
