    Default Use of SQL query and dimension lookup/update together

    hi all....

    In my transformation i want to use both sql query and dimension lookup / update.. sql query for updating the rows and dimension lookup/update for the insert due to the requirements. But this combination is creating problem and giving error after running for long time, like" Lock wait timeout exceeded; try restarting transaction"
    What exactely this error means.??
    Is this combination is not applicable in kettle , due to some technical issues???
    Please help....

    Thanks in advance

    Hi meenaiyer,

    I did work that similar to your case. in my case,
    DMBS is Oracle and PDI's version is 3.1 RC1.

    I try it using Combination lookup/update and Update step.
    first time, I got a wired error. I think its a transaction problem. so, I enabled 'unique connection' on transformation' configuration.
    after that, it works as I would expected.

    please see wiki doc,

    yw kim.
