Hi Helmut,
As per sap note Note 1006496 - Feature list for SAP MaxDB/liveCache 7.7
Please refer to the following:
The old 'plain text' file format for knldiag, knldiag.err, and other database log files is no longer supported. The new files KnlMsg or KnlMsgArchive are written in 'Pseudo XML'. To read those files, they must first be converted using PROTCONV (automatic process in Database Studio, Database Manager GUI, or transactions DB50 and LC10).
For additional information, see SDN:
'HowTo - knldiag Message File Format in MaxDB7.7' https://wiki.sdn.sap.com/wiki/x/PwErAg)
(7.7.00. 00)
This has examples, and will assist you in your quest.
Kind Regards,
Johan
