Env:  Ubuntu 20.04  When install too many versions of docker on the same machine,  it could have a weird mount behavior. I have a folder called /media/xxx/uuid/prod/db, hereafter, "local db folder".   and I mount this folder to the /db folder inside container, hereafter "container db folder".    I start container like this:  docker run --rm --mount type=bind,source=/media/xxx/uuid/prod/db,target=/db image:latest As you can expected, something happened. the container was  up and running.  the mount seemed not right. If I add a new file to the local db folder , the new file was not available in container db folder ,  and vice versa,  if I add a new file to the container db folder ,  the file wasn't available in the local db folder either.   Looks like the local db folder and container db folder wasn't mapped.   Run docker inspect, I could see the mount configure was correct, from  /media/xxx/uuid/prod/db to /db However, if I stopped the container, and create

  Automation and optimization are high on the list for all organizations. A key part of this in SCD is the Transaction STP feature which enables you to automate the way transactions are processed and only deal with exceptions. In this piece, we will take a look at some of the tools that can be used to help users handle the process. Start by looking at the Message Queue window where the STP queues are defined (Message queue type = STP queue). In this window, we want to point to the field Maximum Age . As with other message queues, this defines the number of days after which a ‘Finished’ message will be deleted (provided this has not been disabled in the Service Options window). For an STP queue, this means the number of days after a transaction has reached the highest status possible, which at many client installations is ‘Final GL’. However, the transaction is of course not deleted, rather the message status is changed from ‘Queued’ to ‘Removed’ and it is no longer part of the STP. F

Although I am highly regarded and respected, I want to make sure that my leadership style continues to be one of encouragement, motivation, and development versus one that turns people off and they therefore do not want to follow me and my vision.” must learn to recalibrate to a definition of success based on the team’s collective performance  have a broader vision and a deeper sense of the strategic and competitive landscape . They noted that the technical and functional skills that enabled high potentials to excel may in fact impede their ability to see the “big picture.”   Paradoxically, while empathy tends to decline as one moves up, that is when it is most needed, especially when one is leading and not doing.
