Known Issues

This section provides recommendations and workarounds for the following issues:

• Maximum Threads Setting
• Maximum Kernel Setting
• QuickStart Does Not Invoke Netscape 4.7x
• Apache Server Hangs If ld and libdld.sl Are Obsolete

For more information about known issues with any components of this release, see the appropriate Release Notes document. For a complete list of Release Notes supporting WebLogic Platform 7.0, see:

http://download.oracle.com/docs/cd/E13196_01/platform/docs70/interm/relnotes.html

Maximum Threads Setting

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

Maximum Kernel Setting

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 shows recommendations for kernel configuration parameters.

Table 5-2 Recommended HP-UX 11.0 Kernel Settings

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

 

QuickStart Does Not Invoke Netscape 4.7x

If the LANG environment variable is set to C on your system (LANG=C) and you select Netscape 4.7.x as your browser, then QuickStart may fail to start. To fix this problem, terminate QuickStart, unset the LANG environment variable (manually or by using a wrapper function), and restart the QuickStart application.

This problem is reported in CR082062.

Apache Server Hangs If ld and libdld.sl Are Obsolete

If the Apache server hangs when you are trying to use the BEA Apache plugin mod_wl_20.so on an HP-UX platform, then you are probably using an obsolete version of ld and/or libdld.sl. Apache binaries require the B.11.32 (or higher) version of ld and libdld.sl.

To determine which version of ld is installed on your system, complete the following procedure:

Enter: ld -V
Enter: what /usr/lib/libdld.sl

The version numbers of ld and libdld.sl are displayed.

• If both ld and libdld.sl have the same version number and that number is 11.32 or higher, then you are using the appropriate versions and you can quit this procedure; you are ready to run the mod_wl_20.so plugin.
• If the version numbers for ld and libdld.sl do not match, or if the numbers match and that number is lower than 11.32, then you need to install an HP patch. For instructions, proceed to step 3.
Determine which patch you need for your system:
• For an HP-UX 11.00 platform you need PHSS_26559.
• For an HP-UX 11i (11.11) or higher platform, you need PHSS_26560.
