Re: jt400.jar in use

I agree with Dan. Exclude it from your save since it is easily
recovered in other ways, and does not change very often. Your
monthly/Quarterly full system saves should be plenty. (or after a
group/cumulative installation)

jt400.jar is the Toolkit for Java. It contains the JDBC database drivers

for Java as well as a whole bunch of java classes for accessing IBMi API's.
It might have been in use from iNav or one of the HTTPSVR instances.

Subject: jt400.jar in use

All,

I've spent a couple of weeks re-engineering our nightly BRMS backup to

be as much save-while-active (SWA) as possible (the subject of a rather
long thread here).

I put it in production today and it ran flawlessly except for one little

hiccup. This *LINK object, /QOpenSys/QIBM/ProdData/acsi/lib/jt400.jar, was
not saved because it was in use. This was at 4:19am with no users signed
on. Controlling subsystem would have been started about 1 hour earlier,
and subsystem QHTTPSVR would have been ended when the error occurred.

When I drilled down in Navigator, it did indicate the file had been used

today, but does not give a time. There is no WRKOBJLCK equivalent for IFS
files, but I found this online CALL QP0FPTOS PARM(*LSTOBJREF
'/ifspath/ifsfile' *FORMAT2) that showed me there were no locks on it now.

<g>

I had tested the *LINK save as SWA close to a dozen times over the past

10 days and this particular file never showed up as being in use. My
question is, essentially, why today? Was this a fluke? How can I find out
what was using this file at that time?

I did download and stage the latest Java group PTF yesterday afternoon,

to be applied the next IPL, if that makes a difference.

I just don't want this file getting missed every day.
