Can some one tell me the ressolution for the error. I was not able to answer this question in wipro interview.
"The transaction exceeded the maximum number of rowhash locks allowed"

Answer Posted / dotnetchampion

This error is returned when a transaction has exceeded the number of rowhash locks allowed. The threshold on the number of rowhash locks allowed is defined in DBSControl via the General field ’MaxRowHashBlocksPercent’. This is done so that one transaction does not fill up the lock table with rowhash locks. The number of control blocks/locks that can fit into an AMP lock table is defined by STDMAXLOCKBLOCKS which is currently ~51860.
