NAME

max_acct_file_size — defines the maximum accounting file size

VALUES

Failsafe

2,560,000 bytes

Default

2,560,000 bytes

Allowed values

Between 2,560,000 and 2,147,483,647 bytes.

Recommended values

2,560,000 bytes

DESCRIPTION

max_acct_file_size is a dynamic tunable that limits the maximum accounting file size. See acct(2) and acct(4). If max_acct_file_size was set to a value that is not a multiple of the accounting record size, the tunable will be rounded up to the next full record silently unless the maximum limit is reached. In this case, the tunable will be rounded down to the nearest full record silently.

The only exception to this rule is when the max_acct_file_size is set back to its default value. The system will accept 2,560,000 without rounding up even if it was not a multiple of the accounting record size. This is done to preserve binary compatibility with previous releases of HP-UX.

Who is Expected to Change This Tunable?

System administrators that wish to allow accounting files to grow beyond the default.

Restrictions on Changing

None.

When Should the Value of This Tunable Be Raised?

If there is a need for larger accounting files than the default.

What Are the Side Effects of Raising the Value?

Accounting tools that assume accounting files no more than 2.5 MB in size might not be able to handle larger files.

When Should the Value of This Tunable Be Lowered?

The default value is also the minimum value. If the value of max_acct_file_size was raised it can be lowered again if large accounting files were not desired.

What Are the Side Effects of Lowering the Value?

None.

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.

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 tunable values, consult the documentation for the kernel software being installed. For information about optional kernel software that was factory installed on your system, see HP-UX Release Notes at http://docs.hp.com.
