System Status Components and Related Exceptions

 

 

 

Description

Code

Explanation

 

 

 

DDF bytes received

TRCV

The amount of data received by a requestor (allied) or server

 

 

(distributed) DB2 thread in response to SQL requests

 

 

exceeds the threshold.

 

 

 

DDF bytes sent

TSND

The amount of data sent by a requestor (allied) or server

 

 

(distributed) DB2 thread in response to SQL requests

 

 

exceeds the threshold.

 

 

 

DDF remote CPU

RCPU

The amount of CPU time used by a distributed data access

time

 

thread exceeds the specified threshold.

 

 

 

Active thread exceptions

The following exceptions apply to active threads.

Description

Code

Explanation

 

 

 

Archive log mount

ARCM

Thread backout processing is waiting for an archive tape

needed

 

mount.

 

 

DB2 requires the archive tape mount during abort

 

 

processing to backout changes made in the current unit of

 

 

recovery. The thread does not do any processing until the

 

 

tape is mounted. It holds DB2 resources until the abort

 

 

request is complete.

 

 

 

CPU utilization %

TCPU

CPU utilization for an address space that has DB2

 

 

connections and threads exceeds the specified threshold.

 

 

 

Getpage/read ratio

GETP

The ratio of logical page read (getpage) requests to physical

 

 

page read (read I/O) requests is less than the specified

 

 

threshold.

 

 

 

In-DB2 CPU time

IDBC

The amount of CPU time used by DB2 to process a thread is

 

 

greater than the specified threshold.

 

 

 

In-DB2 time

IDBT

The length of time that DB2 has been processing a thread is

 

 

greater than the specified threshold.

 

 

 

Page lock owned %

LKUS

The percentage of page locks owned by an active thread to

 

 

the total allowable number of held page locks exceeds the

 

 

specified threshold.

 

 

 

Page update rate

PGUP

The number of row updates per second on behalf of a

 

 

thread exceeds the specified threshold.

 

 

 

Resource limit

RELM

The ratio of the resource limit high water mark (CPU

percent

 

seconds) to the resource limit in effect (CPU seconds) is

 

 

greater than the current threshold value of nn.n%.

 

 

 

Sequential prefetch

PREF

The number of sequential prefetch requests per second

rate

 

exceeds the specified threshold.

 

 

 

Synch read I/O rate

RIO

The physical read I/O rate per second on behalf of a thread

 

 

exceeds the specified threshold.
