DB2 FOR LUW / DB2FORLUW / B10 - DB2

In the environments where a rotating Db2 diagnostic log is
enabled, i.e. where:
$ db2 get dbm cfg | grep DIAGSIZE
shows a non-zero value, certain messages from db2havend process,
which is responsible for the interaction between Db2 engine and
high availability software (e.g. IBM TSAMP), will always be
logged to the default file named db2diag.log and not the
rotating one (one, with a numerical suffix, e.g.
db2diag.10.log). This is an example of a message of this kind
(note PROC : db2havend):

2018-11-02-05.26.49.624162-420 I2105E413             LEVEL:

db2haEnableResourceGroup, probe:10359
MESSAGE : Issuing unlock request against resource group.
DATA #1 : String, 29 bytes
db2_db2v111_db2v111_SAMPLE-rg

This APAR will address this behavior.
