DAS restarting function of OutOfMemoryError

DAS sometimes stop the function.

Customer need to call us about the trouble.

The DAS process is running but "das-nohup.out" shows "Out of memory".

Title CPACS: Using DAS Monitor Script to help improve DAS Performance

KM URL https://gehealthcare-svc.lightning.force.com/lightning/articles/HCIT_Knowledge_Article/DAS-Monitor-Script

We have das_mon.sh but it can not use on CPACS7.0 because those are have the similar function.

**Not intended for CPACS 6.0 SP10 or greater versions, which have a DAS Monitor-like feature built in.

In addition, das_mon.sh is check the Out of memory issue but it catches "Out of Memory", not "OutOfMemory".

# Out of Memory Check

echo "`date` - Checking das-nohup for memory alerts..." | tee -a $LOGFILE

if [ -f /flamingo/log/das/das-nohup.out ];then

if [ `tail -10 /flamingo/log/das/das-nohup.out | grep "Out of Memory" | wc -l` -gt 0 ];then

echo "`date` >>>ALERT 128: The das-nohup.out is showing Out of Memory messages!" | tee -a $LOGFILE

SaveDasLog

das_restart

BOUNCE_TRIG=$((BOUNCE_TRIG+1))

chk_proc

else

echo "`date` - No [Out of Memory errors] found in das-nohup.out." | tee -a $LOGFILE

fi

else

echo "`date` >>>INFO 129: The das-nohup.out is not found!" | tee -a $LOGFILE

exit

fi

I don't know the detail of "a DAS Monitor-like feature built in".

However I hope to add DAS restarting function when it catches "Out of Memory" or "OutOfMemory".
