Overview
We try to keep the need to install PTFs to a minimum for QSystem Monitor. Unfortunately, sometimes this need cannot be avoided if the APIs that we use have errors that require correction. The topic provides a brief explanation of which API or MI interface the PTF is fixing, whether it is a mandatory or an optional requirement, and the impact if not applied.
V7R2M0
SI52785, superseded by SI56826
Recommended
When Collection Services cycles, Management Central monitors using job data may fail with message MCH0601 sent to the associated QZRCSRVS job. See APAR SE57930 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
V7R1M0
MF48890, superseded by MF59685
Mandatory
A problem was noticed whilst running the Disk Collection routines. The underlying problem was caused by a deadlock situation between #MNCOL and #MNMATC, when a seize on a library was not being properly released. See APAR MA38790 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
SI52471, superseded by SI56900
Recommended
When Collection Services cycles, Management Central monitors using job data may fail with message MCH0601 sent to the associated QZRCSRVS job. See APAR SE57930 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
MF56844, superseded by MF59539
Optional
If you're using the Cache Battery monitoring feature the Telnet SSL may fail new secure connections. QTVTELNET shows message CPDBCA9. See APAR MA42715 for IBM’s explanation.
Impact: The PTF prevents an underlying OS problem.
V6R1M1
MF48670
Mandatory
A problem was noticed whilst running the Disk Collection routines. The underlying problem was caused by a deadlock situation between #MNCOL and #MNMATC, when a seize on a library was not being properly released. See APAR MA38790 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
MF56845, superseded by MF59538
Optional
If you're using the Cache Battery monitoring feature the Telnet SSL may fail new secure connections. QTVTELNET shows message CPDBCA9. See APAR MA42715 for IBM’s explanation.
Impact: The PTF prevents an underlying OS problem.
V6R1M0
MF48669
Mandatory
A problem was noticed whilst running the Disk Collection routines. The underlying problem was caused by a deadlock situation between #MNCOL and #MNMATC, when a seize on a library was not being properly released. See APAR MA38790 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
MF55269, superseded by MF59537
Optional
If you're using the Cache Battery monitoring feature the Telnet SSL may fail new secure connections. QTVTELNET shows message CPDBCA9. See APAR MA41895 for IBM’s explanation.
Impact: The PTF prevents an underlying OS problem.
V5R4M5
MF41414
Mandatory
Large temporary storage growth was noticed on a couple of systems. The growth was linked to the use of DSPFD with the *MBRLIST option. See APAR MA34693 for IBM’s explanation.
Impact: The PTF prevents errant disk storage growth.
MF48668
Mandatory
A problem was noticed whilst running the Disk Collection routines. The underlying problem was caused by a deadlock situation between #MNCOL and #MNMATC, when a seize on a library was not being properly released. See APAR MA38790 for IBM’s explanation.
Impact: The PTF avoids a potential object deadlock problem.
MF56394
Optional
If you're using the Cache Battery monitoring feature the Telnet SSL may fail new secure connections. QTVTELNET shows message CPDBCA9. See APAR MA42467 for IBM’s explanation.
Impact: The PTF prevents an underlying OS problem.

SI27805
Optional
You only need to install this PTF if you're using the QTEMP monitoring feature.
