    What is database failure scenario in DB2??

    Can we detect database failure by looking at any process or something else??

    all is in diaglog - the forum would not have enough space to mention all failures you can get..
    there are many docs in that document failing scenarios (and for testing) and how db2/hadr/tsa act on these
    db2pd -d xx -hadr returns some status --- lssam for tsa or db2pd -ha

    Good DBAs are not formed in a week or a month. They are created little by little, day by day. Protracted and patient effort is needed to develop good DBAs.
