NAME
fs_symlinks - maximum number of symbolic links used to resolve a path name VALUES
Failsafe Default Allowed values The minimum value allowed is 20. The maximum value allowed is 1024, or 1K. Specify a positive integer value. DESCRIPTION
The tunable represents the maximum number of symbolic links followed by the kernel when resolving a path name. Applications that create symbolic links and/or parse path names should also now use this limit represented by to be consistent with the kernel. Who Is Expected to Change This Tunable? Anyone expecting to run applications using path names that may expand to a large number of symbolic links. Restrictions on Changing None. The tunable is dynamic (tuning will take effect immediately on the running system). When Should the Value of This Tunable Be Raised? This tunable value should be raised when applications are expected to create and/or parse path names that may expand to a large number of symbolic links. What are the Side Effects of Raising the Value? None. When Should the Value of This Tunable Be Lowered? This value rarely needs to be lowered, unless there is a reason to limit the number of symbolic links in an expanded path name. What are the Side Effects of Lowering the Value? The kernel will not be able to resolve path names with more symbolic links than the limit represented by What Other Tunable Values Should Be Changed at the Same Time? None. WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. NOTE: The define traditionally defined in is now obsolete and should not be used. This limit (number of symbolics links that may be expanded in a path name) is now available to applications via this new tunable parameter, The interfaces provided by the tunable infra- structure should be used to obtain the value of At the application level, use the gettune(2) or kctune(1M) interface. Applications using the define may not be consistent with the kernel. The define will be removed in post-HP-UX 11i Version 2 releases. Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed.

NAME
maxuprc - limits the maximum number of concurrent user processes per user VALUES
Failsafe Default Allowed values Recommended value DESCRIPTION
is a dynamic tunable that limits the maximum number of processes per user. Only root can have more than the number of processes limited by Who is Expected to Change This Tunable? System administrators can change the value of depending on the usage of the system. Restrictions on Changing None. This tunable is dynamic. When Should the Value of This Tunable Be Raised? The value of should be changed if users require more processes than what they are currently allowed by If fails with an error value of it could be an indication that was reached by that particular user. However, that is not the only reason that could cause to fail with an errno value of may be returned if system tunable has been reached or memory on the system has been exhausted. What Are the Side Effects of Raising the Value? Raising the value of allows a single user to consume a greater percentage of the system resources. When Should the Value of This Tunable Be Lowered? The value of should be lowered when individual users are monopolizing system resources by running too many concurrent processes. What Are the Side Effects of Lowering the Value? Applications that depend on a large number of processes may behave differently or fail. Existing processes will continue to run but new process creations which would result in the user exceeding will fail. What Other Tunable Values Should Be Changed at the Same Time? When tuning you should keep in mind the value of WARNINGS
