Java SDK for VFTP Agents
VitalSigns for FTP Agents use Java to communicate with the VFTP Database Server. Adequate Java support is typically present on z/OS and no maintenance is necessary.
Agents require 31-bit Java SDK at the Server’s host. They cannot work with 64-bit Java.
To learn whether IBM’s Java SDK is installed, look for the file
/bin/javac. To learn which SDK version is available to the VFTP Agent, give the command
JavaSDKdirectory means the directory where the SDK resides. The command’s output will indicate the Java version. It may also provide warning messages.
A new 31-bit SDK is free of charge and simple to install. Follow this link: IBM’s Java Technology Edition. IBM lists several supported versions, in 31-bit and 64-bit forms. VFTP Agents will work with any of the 31-bit versions, and none of the 64-bit versions.
Java applets work much faster when Java files are downloaded to the client machine once, then saved for later use. In addition, a bug in Java 7 causes a VIP 8.0 client to completely fail when caching is disabled.
Enable Java caching as follows:
- Open the Java Control Panel.
In task bars and program lists, look for the coffee cup icon and double-click on it.
- In the control panel, select General, then look for Temporary Internet Files, Settings….
- In Temporary Files Settings check the box labeled
Keep temporary files on my computer.
- In the lower-right, click on OK, then Apply.
- Restart your web browser.
