Known Issues

The HP-UX 11.0 default value for maximum threads per process is 64, which may be too low for WebLogic Server and many Java server applications in general. When the value is too low, WebLogic Server may have problems starting up.

BEA recommends 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 (the maximum number of kernel threads). The following table provides some examples. Parameter Old Value New Value Description max_thread_proc 64 1024 Maximum threads per process maxfiles 60 256 Soft file limit per process maxusers 32 256 Influences other parameters nkthread 499 3635 Number of threads total on the system nproc 276 2068 Maximum number of processes ncallout 292 2084 Number of pending timeouts

The cacerts file under ${BEA_HOME}/jdk141_01/jre/lib/security is corrupt. For a new version, see HP's developer site. For demonstration purposes use the following file: ${WL_HOME}/server/lib/cacerts.
To avoid OutOfMemory exceptions or JVM crashes, increase the values of three Java options: -Xms, -Xmx, and -XX:MaxPermSize.

Parameter	Old Value	New Value	Description
`max_thread_proc`	64	1024	Maximum threads per process
`maxfiles`	60	256	Soft file limit per process
`maxusers`	32	256	Influences other parameters
`nkthread`	499	3635	Number of threads total on the system
`nproc`	276	2068	Maximum number of processes
`ncallout`	292	2084	Number of pending timeouts

The following values are suggested: -Xms200m, -Xmx512m, and -XX:MaxPermSize=128m.
