Tabel with more than 1 acces

[Torsten Schumann]

Hello,
one more problem. we have some tables on which more than one application will select or write in this table. Sometimes we get following Error: "Beim Warten auf eine Sperre wurde die zul�ssige Wartezeit �berschritten. Bitte versuchen Sie, die Transaktion neu zu starten"
SQL: update eledb.t_ordathistory set time_created = str_to_date('04.11.2013 13:00:14','%d.%m.%Y %H:%i:%s') where ordat_sequence = 2264375;

translated:"While waiting for a lock tolerances on the waiting time was exceeded. Please try to retry transaction"

can anyone help and tell me what is wrong???

On this table working 4 Applications with read and write options.
It's a Mysql Cluster db

Thx T.Schumann
