AGGREGATION FIELDS field (ACCUMUID subsystem parameter)

The ACCUMUID subsystem parameter determines the aggregation fields that are to be used for DDF and RRSAF accounting rollup.

Acceptable values: 0–17
Default: 0
Update: option 23 on panel DSNTIPB
DSNZPxxx: DSN6SYSP ACCUMUID

The values are defined in the following table.

Table 1. Values for the aggregation fields that are used for DDF and RRSAF accounting rollup
Value Rollup criteria String of X'00' or string of X'40' considered for rollup?
0 User ID, application name or transaction name, and workstation name Yes1
1 User ID No
2 User application name or transaction name No
3 User workstation name No
4 User ID and application name or transaction name Yes1
5 User ID and workstation name Yes1
6 User application name or transaction name and workstation name Yes1
7 User ID, application name or transaction name, and workstation name No
8 User ID and application name or transaction name No
9 User ID and workstation name No
10 User application name or transaction name and workstation name No
11 User ID, application name or transaction name, and workstation name Yes
12 User ID Yes
13 User application name or transaction name Yes
14 User workstation name Yes
15 User ID and application name or transaction name Yes
16 User ID and workstation name Yes
17 User application name or transaction name and workstation name Yes
Note:
  1. At least one value in the set of criteria must have a value other than a string of X'00's or a string of X'40's.

For example, if a thread has the user ID set to a string of X'00' and the workstation name set to myws, the thread qualifies for rollup if ACCUMUID is set to 5, but not if ACCUMUID is set to 9.

Assume that ACCUMUID is set to 5. The threads in the following table all qualify for rollup.

Table 2. Values for user ID and workstation name
User ID Workstation name
myuser myws
myuser A string of X'40'
A string of X'40' myws
myuser A string of X'00'
A string of X'00' myws

The thread with user ID set to myuser and workstation name set to a string of X'40' and the thread with user ID set to myuser and workstation name set to a string or X'00' are included in the same rollup record. The thread with user ID set to a string of X'40' and workstation name set to myws and the thread with user ID set to a string of X'00' and workstation name set to myws are included in the same rollup record.

Db2 writes individual accounting threads for threads that do not meet the criteria for rollup.

The value of ACCUMUID is ignored if the value of ACCUMACC is set to NO.
