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


 

• When you start a server the following entry appears in the server log file:

####<Apr 25, 2003 4:04:13 PM EDT> <Critical> <EmbeddedLDAP> <mymach>
<server1> <main> <<WLS Kernel>> <> <BEA-171517> <An error occurred
while attempting to get exclusive access to the embedded LDAP data
files directory - .//server1/ldap/ldapfiles. The exception thrown is
java.io.IOException: Invalid argument.>

This message is not critical; it is a known issue with the HP-UX SDK that should be fixed in HP-UX SDK 1.4.1.02.

• The cacerts file under ${BEA_HOME}/jdk141_01/jre/lib/security is corrupt. For a new version, visit 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.

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