• Detector for DB2 for z/OS

Issue/Introduction

Issuing Detector for Db2 for z/OS (PDT) modify command and expected one output file for 10 minutes but get 2 files of 5 minutes:

START(DTR),DYN(Y),SDE(Y),CHV(Y),SCA(Y),SQT(Y),SQLT(Y),PRF(<collection profile>),DB2(<ssid>),INT(0010),RND(Y),PLEXINTV(N),EXT(Y),
DST(<datastore>),HLVL(<hlq>),DUR(0010),AUTO(N),POOL(2000),TRG(Y),KEYS(Y)

Resolution

The PDT collection started at 7:45 and the first interval ends at 7:50 because of the round up RND(Y) option.
At 7:55 the following message PDT0144 DETECTOR COLLECTION TIME LIMIT EXPIRED DB2=ssid is displayed because of the 10 minutes specified for interval time (INT).


Here is how the RND(Y/N) round interval keyword works:
Specify one of the following operands to indicate whether to end the collection interval on a time boundary
that is an integral multiple of the interval time.

Y
Rounds the end of the interval to an integral boundary. If you specify Y, also specify INT(Y).

N
Does not round the end of the interval.

Default: Y
