Re: jt400.jar in use

I am rather curious too.

But, people in the stream file world often do a lot of deletes. For
example,
data20130129082938.log
may get purged automatically. You may not want to restore these. However,
I can see where not keeping track of this stuff shouldn't be a default.
I'll withhold further comment pending outcome of your pmr.

Another thought, if you truly do a FULL system save, and that file was
deleted before the full system save then the BRMS recovery report
shouldn't include any previous save. It just shouldn't restore it. But
if you did a wrklnkbrm it should retain the older volumes until those
volumes are expired and reused.

Does it think your library save was incremental, but your stream file save
was full? In that case, I can see it acting like what you've experienced.

Today, a different single file was not saved. It was:


/QIBM/ProdData/OS/OSGi/LWI71/runtime/isc/eclipse/plugins/com.ibm.isclite_7.1.1.6.jar

The jt400.jar file that was NOT saved yesterday WAS saved today. I made
no
changes.

And the BRMS recovery report run this morning says I need both yesterday's
and today's tape for recovery. I thought "good news!" in that it would
tell me I needed yesterday's tape to recover the file mentioned above. But
it was not to be. The reason BRMS says I need yesterday's tape is because
I deleted an old test library yesterday. I need yesterday's tape to
restore that now deleted library. No reference to needing it for *LINK
restore.

Evidently BRMS doesn't keep data to the same level of granularity on
*LINK.
I may just open a PMR later and see what the IBM BRMS people have to say
on this.

Dan & Jim,

I understand what you are saying with regard to not worrying about

saving

this file, jt400.jar, but I'm just not comfortable with it. I don't

want

to start a list of files that I have to go find somewhere when a

recovery

is necessary. Not even one.

In addition, the recovery report generated by BRMS after this morning's
backup states the only tape I need for recovery is the tape I used this
morning. Even though jt400.jar was not saved. The recovery report

should

also tell me that I need the tape used yesterday morning when jt400.jar

WAS

saved. Why doesn't it tell me that? I simply don't understand why.

What

else isn't BRMS telling me? I looked at the WRKLNKBRM command and

drilled

down to the jt400.jar file in question. It is listed on the tape used

this

morning as size 0 bytes, and says it was NOT saved. It does show under
yesterday's tape as being saved. Again, why doesn't BRMS tell me I need
yesterday's tape? This situation, all by itself, really makes me

nervous.

People keep telling me not to worry about this file or that file or that
directory. Performance data and log files I understand. I just can't

make

myself go further with it.

My goal was to do a complete 100% save of the system 5 mornings a week,
with as little downtime as possible. I'm slowly coming to the

conclusion

it cannot be done, unless I do the entire backup completely restricted.
That's what I'm doing now without all this study and testing. I'm not
sure where I'm heading now. Do this "new" BRMS control group Mon-Thu

and

do the old, completely restricted, BRMS control group on Fridays? I

just

don't know.

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

It

is easily recovered if necessary.

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.
