I have a system that is running IBM i 7.1, and decided to install--
5761JV1 option 14 for SE 7 32 bit, since I needed to load a Java based
tool called Talend ETL in order to do a POC. The install went fine
and I was unaware of any problems until the next day. Our BI
reporting site was down and I discovered that DB2 Web Query (Std Ed)
failed to start- siting various prerequisite PTFs were not installed.
It mentioned a few, so I looked at the PTF group levels. Turns out
that 4 groups had levels that now said "Not Installed'.
I reasoned there might be two causes. Either Web Query automatically
switched to using Java 7, or perhaps it only checks PTF group levels
at startup instead of only what it actually needs. I should be able
to test this on the weekend, but in the interest of getting our BI
site up as quickly as possible, I did not think to see which version
it was using at the time. I did however check that the system default Java was still 1.6.
To get things up and running again, I uninstalling Java 7 and
fortunately the PTF groups all went back to "installed" status. I
restarted web query and it was fine. The four PTF groups that went to
"uninstalled" after installing Java 7 were SF99710 (Cum), SF99647 (DB2
Web Query), SF99572
(Java) and SF99368 (HHTTP).
I've installed new LPP and/or options many times before, and never had
previously installed LPP's fail by installing another new LPP or new
option. I always realized I would have to apply PTF's again for newly
installed products before using them, but never thought it would
affect existing products. Have anyone ever experienced this before?
