4.7.2 Procedure to move the time back on the JP1/AO server

To move the time back on the JP1/AO server, you must restart the product.

In a cluster system, change the time on both the active server and the standby server. For the procedures to start and stop the JP1/AO system, follow the instructions in the JP1/Automatic Operation Administration Guide.

To move the time back on the JP1/AO server:

  1. In the Tasks window, check the tasks. If any tasks are in execution status (In Progress, Waiting for Input, In Progress (with Error), In Progress (Terminating), or Long Running), stop execution of the tasks or wait until the task status changes to the ended status.

  2. Stop the JP1/AO service.

    For non-cluster systems:

    Execute the hcmds64srv command with the stop option specified.

    For cluster systems:

    Use the cluster software to bring the service offline.

  3. Note the current time indicated on the JP1/AO server.

  4. Move the time back on the JP1/AO server.

  5. Wait until the time you noted in step 4 is reached, and then start the service.

    For non-cluster systems:

    Execute the hcmds64srv command with the start option specified.

    For cluster systems:

    Use the cluster software to bring the service online.

If you use NTP to automatically correct the time, do not allow it to correct the server time retroactively when the time indicated on the server is ahead of the actual time. In the NTP function for correcting the time automatically, if the time difference falls within a predetermined range, the time is adjusted incrementally, whereas if it exceeds that range, the time is adjusted retroactively all at once. Set the frequency of time adjustments in such a way that the time difference will not exceed the range within which the time can be adjusted incrementally.
