NAME
acctsuspend, acctresume - suspend and resume accounting when available disk space reaches threshold VALUES
Failsafe Default. Default acctsuspend: acctresume: Allowed values acctresume: acctsuspend: Recommended values acctsuspend: acctresume: (But more than acctsuspend) DESCRIPTION
The and tunables control when accounting stops and resumes due to disk space constraints. When free disk space on the file system being used by accounting reaches the suspension threshold, which is the percentage relative to the percentage of disk space available only to the superuser, accounting is suspended until such time as the free disk space reaches the resumption threshold, which is the percentage rela- tive to the percentage of disk space available only to the superuser. Note: Since the and values are specified relative to the percentage of disk space available only to the superuser, negative values of these parameters can make sense. For example, if the superuser has reserved 10 percent of the disk space on the file system at file system creation time, and acctsuspend is -5 and acctresume is 0, the suspension threshold will be 5 percent of the total disk space and the resumption threshold will be 10 percent of the total disk space. Who Is Expected to Change This Tunable? Anyone using accounting. Restrictions on Changing Changes to this tunable take effect at the next reboot. When Should the Value of This Tunable Be Raised? Increasing either variable should be considered when it is necessary to maintain a higher percentage of free space on the accounting filesystem. What Are the Side Effects of Raising the Value of This Tunable? The higher either value is, the less accounting data may be captured. The further the values are separated, the greater the amount of potentially lost accounting data. When Should the Value of This Tunable Be Lowered? If additional disk space is needed for accounting data, and it cannot be obtained by moving files off of the filesystem, then the value of should be lowered. What Are the Side Effects of Lowering the Value of This Tunable? Filesystem performance (writing accounting records) decreases as the filesystem fills up. In turn, this will decrease the overall perfor- mance of accounting processes. What Other Tunables Should Be Changed at the Same Time? When changing either of these tunables, both should be considered. 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. For information about optional kernel software that was factory installed on your system, see at AUTHOR

audit_memory_usage(5)						File Formats Manual					     audit_memory_usage(5)

NAME
audit_memory_usage - percentage of physical memory that can be used by audit subsystem VALUES
Failsafe Default Allowed values Recommended values DESCRIPTION
The tunable defines the percentage of physical memory that can be used by audit records. If the audit record memory usage exceeds the limit, the audit subsystem blocks the system call until memory usage comes down inside the limit. Who Is Expected to Change This Tunable? Administrator with proper privileges can change the value of Restrictions on Changing This tunable value can be changed any time, as this is a dynamic tunable; but its value can not be lowered below the memory currently used by the audit subsystem for records. When Should the Value of This Tunable Be Raised? When the system to be audited is critical and generates many records. What are the Side Effects of Raising the Value? If the system is generating great number of records, and the value is raised, then it can create a lot of unflushed memory and might slow down the system. When Should the Value of This Tunable Be Lowered? When the audit subsystem is not generating many records. What are the Side Effects of Lowering the Value? If many audit records are generated, then the auditing subsystem might block the system call. What Other Tunable Values Should Be Changed at the Same Time? None. WARNINGS
