fcache_seqlimit_file(5) 					File Formats Manual					   fcache_seqlimit_file(5)

NAME
fcache_seqlimit_file - percent of file cache that can be consumed by sequential accesses, per-file limit VALUES
Failsafe Default Allowed values The minimum value allowed is The maximum value allowed is Specify a positive integer value. DESCRIPTION
This parameter places a per-file limit on how much memory can be consumed in the file cache by sequential accesses. It is important to note the relationship between this tunable and the system-wide limit tunable, These two tunables, in conjunction, control how much memory in the file cache can be consumed by sequential accesses. When sequential accesses to a file has exceeded the per-file limit AND the system-wide limit, the excess file cache pages are paged out. Note that both limits have to be reached in order for page stealing to occur. For example, a file can exceed its limit if the limit has not been reached. Similarly, no page stealing occurs if none of the files on the system has exceeded the per-file limit, even if the sys- tem-wide limit has been hit. The page stealing feature is specific to improving sequential I/O performance for large files. Limiting the file cache memory consumption helps alleviate memory pressure in the file cache. It also prevents cache wiping -- a single thread sequentially accessing a large file can wipe out the existing contents of the file cache. Who is Expected to Change This Tunable? System administrators that run applications which do large sequential file I/O's. Typically, these files are larger than the size of phys- ical memory on the system. Restrictions on Changing Changes to this tunable take effect immediately. When Should the Value of This Tunable Be Raised? When you wish to allow greater file cache consumption due to sequential accesses. Setting and to 100 effectively disables the sequential access page stealing feature. What Are the Side Effects of Raising the Value? Setting the tunable too high may yield poor performance for large sequential I/O's for large files (larger than physical memory size). and should be tuned appropriately for the anticipated workload. When Should the Value of This Tunable Be Lowered? When you wish to limit file cache consumption due to sequential accesses. Setting and to 0 forces sequential access page stealing to always occur. What Are the Side Effects of Lowering the Value? Could cause more pageouts to occur in an attempt to limit the file cache consumption. What Other Tunable Values Should Be Changed at the Same Time? and should be changed at the same time. 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. 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.
