lagging behind if the difference between the time of last read audit trail

record and the time of the current audit trail restart position is equal to or

greater than CHKPTWARNTDIFFB. In release v3.980B the Collector was

enhanced to produce EMS warning messages if the bi-directional restart

position is not advancing within a threshold defined by the

CHKPTWARNTDIFFB parameter plus 12 more bi-directional flush

intervals (1 additional hour by default). A message will be generated if the

bi-directional restart position falls out of tolerance. A message will be

repeated every CHKPTWARNRATE interval if it remains out of tolerance.

When it is determined to be back within range, a message is generated to

indicate this. In v4.090 the maximum value was increased from 32767 to

2147483647 (from a 16-bit value to a 32-bit value).

CHKPTWARNTDIFFB is specified in seconds, from 0 to 2147483647.

The checking is disabled when CHPTWARNTDIFFB is set to 0. The

default is 8100 seconds (2.25 hours). 2.25 hours is the standard window

that the HP Shadowbase Collector maintains for the bi-directional restart

position. Note that CHKPTTIME must be set for the check to be

performed. CHKPTTIME is also used for the check associated with the

existing CHKPTWARNTDIFF parameter (used to check the normal restart

position to make sure it is advancing).

1.000 None Valid CPU number Yes

Specifies the processor where the Collector runs. It is required to add a

Collector. Cpu_number must be a valid CPU for your system.

Note: That the CPU can be altered at any time. If altered, the new value

will be used in the event a restart is performed.

4.080 -1 Valid CPU number list Yes

This parameter specifies a list of processors to be used for starting the

related COLL or CONS object process. Up to 16 can be specified (0

through 15). The order of usage is the order of the cpu list. If a processor

is not available, the next in the list will tried. Note that when the CPULIST

is specified, the CPU and BACKUPCPU will not be considered. An

appropriate EMS messages will be logged to indicate if a problem

occurred attempting to use a processor. A message will be logged to
