Socket error - Connection reset by peer

0 votes
532 views

I have a simple housekeeping session that deletes data prior to one month from teradata tables.This is done using SQL transformation.The mapping has logic such that it handles 3 types of files (daily , monthly first week ,monthly -last week).logic for all 3 types is same.Deleting data prior to 1 month.Router is used to handle this.

The session executes properly for low volume of data(daily file) but when the table has higher volume of data in production , it gives below error :

TRANSF_1_1_1> pmsql_50065 [ERROR] ODL error: FnName: Close -- [Teradata][Unix system error] Socket error - Connection reset by peer FnName: Execute Direct -- [Teradata][Unix system error] 104 Socket error - Connection reset by peer ODBC call to SQLError failed. . TRANSF_1_1_1> CMN_1761 Timestamp Event: [Fri Aug 08 09:45:01 2014]

We have tried re-executing the session but no luck. Weird part is the delete command is being executed in database as we could see data deleted as required but the session is failing.

Please let me know what is the issue here and also the solution.Thank you.

Can you check the QueryLog for the exact error? In worst case your session gets automatically killed by some workload management rule using too much resources.

I went through an article of diameter, it mentions " Diameter standard advises that a diameter node to maintain two connection primary and secondary connection". Diameter node uses first connection in normal conditions and go for second one if primary connection is abrupted or not available. How far it is correct and where it is used exactly ?
