We have no issues while running WLS on HP-UX, however on virtual machines (HPVM) the following warning is typical:
<Warning> <Store> <AdminServer> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1296644210931> <BEA-280101> <The persistent file store "_WLS_AdminServer" is forced to use buffered I/O and so may have significantly degraded performance. Either the OS/hardware environment does not support the chosen write policy or the native wlfileio library is missing. See store open log messages for the requested and final write policies. See the documentation on store synchronous write policy configuration for advice.>

HP-UX 11.31 / IA64 / JDK 1.6.0.09 / WLS 10.3.4
This looks like unable to find the wlfileio.so file. Please check this file present there @ wlserver10.3/server/lib/native/hpux or not.
IF the file is available,you need to set LD_LIBRARY_PATH as JAVA_OPTIONS
After including the LIBRARY PATH, still the problem is reoccurs. Its a product bug.
IF the file not available, might be a installation problem.
