Cust were collecting MQ data in SYSVIEW logger MQSDATA--but decided to
recreate it in order to change the logger LS/STG size and retention. After
recreating the logger file SYSVIEW stopped writing data in it--and
cust could not find the reason. MQSDATA logger file is empty.
Cust could not find an error message and the logger looked like working well.
It started the MQSDATA started task--the only thing cust noticed is that is
does not occur the message of the MQ connection.
The problem was solved changing the parm MONITOR-MQS-REQUESTS from No
to Yes in PARMLIB MQSDATA member.
Probably it was set dynamically to Yes and when cust executed re-start with Cold it
got the parm from PARMLIB--that was set to No.
