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
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?
