Cron script

Ciao,

i have the following script call by Cron service.

# set up stone environment
export GS_HOME=/opt/oodb/gsDevKitHome
stonePath=$GS_HOME/gemstone/stones/gestionale
pushd $stonePath >& /dev/null
source $stonePath/stone.env
popd >& /dev/null

if [ -s $GEMSTONE/seaside/etc/gemstone.secret ]; then
. $GEMSTONE/seaside/etc/gemstone.secret
else
echo 'Missing password file $GEMSTONE/seaside/etc/gemstone.secret'
exit 1
fi

date=`date +%Y%m%d_%H%M%S`
backupfile=${GEMSTONE_DATADIR}/backups/${GEMSTONE_NAME}_backup_${date}.dbf

echo "Starting backup: " `date` >> $GEMSTONE_LOGDIR/${GEMSTONE_NAME}_backup.log

cat << EOF | $GEMSTONE/bin/topaz -l -T50000 >> $GEMSTONE_LOGDIR/${GEMSTONE_NAME}_backup.log 2>&1

set user DataCurator pass $GEMSTONE_CURATOR_PASS gems $GEMSTONE_NAME

First questions is relative to topaz call.

When this script call the topaz it required a netldi service run on the server ?

If yes it required a specific netldi port ?

How the system manage this link?

If i launching a direct topaz session i need to define the netldi port with : set gemn !tcp@scandella#netldi:50xxx#task!gemnetobject

Second question:

My environment use the default Seaside maintenance VM.

Now the script, before the backup, call:

run

ObjectLogEntry emptyLog

%

commit

It's correct ?

I think the backup is cleaned without Object entry.

Or the system required a markForCollect cycle before ?

Thanks for any considerations,

Dario

No, because if you run topaz on the same machine as the server, you
can just run topaz and log in.

ObjectLogEntries are persisted and emptyLog just disconnects log
entries. If you have an epoch gc running, it will garbage collect
them, but because you're running a script like here, the log entries
themselves will not be GC'ed.

You have to run markForCollection but then wait for the reclaim as
well (or do reclaimAll).
