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


 

• If you upgrade from 8.1 SP3 to 8.1 SP4 by using SmartUpdate or the Upgrade Installer on an HP-UX 11i V2 on PA-RISC configuration, and then try to use the same tool to downgrade from 8.1 SP4 to 8.1 SP3, the downgrade attempt may fail.

BEA recommends that you set the maxdsiz kernel parameter to a minimum value of 2 GB. This problem is being tracked by CR204521.
