WebLogic HP-UX Platform Support
Latest Certified Release
For general information about HP-UX, see Hewlett-Packard's website.
If you encounter problems locating or loading the HP-UX shared libraries supplied with the WebLogic distribution, see Troubleshooting problems with shared libraries on UNIX.
The latest certified release is WebLogic Server Version 5.1.0. For more information, see Platform certification detail.
For WebLogic Server Versions 3.x and 4.0.x, the jdbcKona/Sybase Type 2 JDBC driver is available for HP-UX 11.0. This is a 32-bit driver, built with Sybase DB-Library. Since DB-Library is not a thread-safe library, jdbcKona/Sybase is supported only with green threads. Green threads do not scale well, and so we do not recommend using jdbcKona/Sybase with green threads in a production environment. Using the Sybase jConnect pure Java JDBC driver with the native threads JVM is a better alternative for a production environment.
For WebLogic Server Versions 4.5.x and above, we recommend that you use the JConnect Type 4 driver available free from Sybase, as the jdbcKona/Sybase driver was deprecated beginning with this release.
The HP-UX 11.0 default value for maximum threads per process is 64, which may be too low for the WebLogic Server and many Java server applications in general. When the value is too low, your WebLogic Server may have problems starting up. We recommend that you use the maximum kernel setting for the max_thread_proc and maxusers parameters. Setting maxusers to a higher value increases other machine-wide limits, such as nkthread (max number of kernel threads).
For example, we have reconfigured our kernel as follows:

WebLogic Server is certified and supported on HP-UX 10.20 using the 1.1.6 HP-UX 10.20 JDK.
The WebLogic Server has known limitations on HP-UX 10.20, primarily due to the lack of native thread support:
We suggest the following kernel parameter configuration for HP-UX 10.20:
