Friends and Experts,
Linux SUSE Server 11 sp 3
Hana 102 on AWS
Multi Host x 4
imdbmaster
imdbworker01
imdbworker02
imdbworker03
Amazon Load Balancer with cookie setting 'sapxslb'
all workers are behind Load Balancer except imdbmaster.
When doing many transaction against the Load balancer I am receiving many 401 responses from the servers? Of about 300 requests i am getting about 150 of those requests are HTTP 401 responses?
I have double checked the packages the .xsjs files reside and they are set with basic, form login.
The distribution of the .xsjs files seems random, where the HTTP 401 response does not pick one .xsjs file over any others.
Another question..
I am running a cron job that is running updates on a very active table, would an update on the table prevent inserts from getting through.. THe cron job runs every 2 minutes. I believe it is blocking other inserts and/or updates to this particular table.. I have turned off the cron job for now and running manually periodically..
Is there a way to trace back what transaction is blocking all the other transactions after i have corrected the errors, Percentage of transactions Blocked..
In the hana cockpit Monitor statements is showing blocked transactions, but during the event I am canceling the longest running requests, which crashes the xsengine server, then I restart the service and repeat the process for these long running transactions.
After the fact is there a way to go back and find the culprit, as this is a production system, and I am more worried about getting it back online than finding the culprit at the moment.
Any and all insight is appreciated.
Thank you for your diligence,
-Z-
