When things go wrong on an iSeries or AS/400, one thing you might check is what PTFs were installed recently. Unless you keep a written log of all items installed on your machine (yeah, right) or have a REALLY good memory, it's hard to determine exactly when a PTF was installed over the last month or two.
As was presented elsewhere, you can get more out of the DSPPTF command by directing the output to an *OUTFILE instead of the screen or a print queue:
DSPPTF OUTPUT(*OUTFILE) OUTFILE(QTEMP/PTFINFO)
Then start interactive SQL and run the following query:
select scstdate, scsttime, scppid, scptfid,
sclib, scxpfid, scstatus, scsptf
from ptfinfo
where substr(scstdate, 7, 2) = '02'
order by scstdate desc, scsttime desc
The resulting display will be all PTF activity in the year '02' in descending order by date and time.
If you want to see a history of your cumulative PTF installs, run this query:
select scstdate, scsttime, scppid, scptfid,
sclib, scxpfid, scstatus, scsptf
from ptfinfo
where substr(scstdate, 7, 2) = '02'
and scptfid like 'TC%'
order by scstdate desc, scsttime desc MORE INFORMATION ON THIS TOPIC
