Reviewing and Managing the PLOG Data Set List

Adabas Event Replicator Subsystem replay processing provides a list of PLOG data sets for which replay processing can be initiated. This list also displays the date and time of the earliest transaction in each PLOG data set. You can use this list to review information about each PLOG and determine which PLOGs you need to replay. You can also delete PLOG data set entries from this list. This might be useful if the PLOG data set list becomes too long. For example, very old PLOG data sets appearing in the list may no longer be of use to you. In this case, you can use this screen to remove their PLOG entries from the list.

Note:
The list of PLOG data sets may not appear or may contain inaccurate information, if the RECORDPLOGINFO initialization parameter is not set to "YES". You can control this parameter setting from the Adabas Event Replicator Subsystem using the Record PLOG information field on the Global Values screen. For more information about the RECORDPLOGINFO initialization parameter, read RECORDPLOGINFO Parameter. For more information about the Record PLOG information field, read Setting Global Values.

    PLOG Data Set Name The name of a PLOG data set for which replay processing can be initiated.
    Replay Enter an "I" in this column to review more information about this PLOG data set. Enter a "D" in this column if you want to delete this PLOG data set entry from the list of PLOG data sets in the Replicator system file as well as all entries for PLOG data sets with transaction dates and time earlier than the deleted PLOG data set entry.
    Time The time of the first transaction in the PLOG data set.

Reviewing PLOG Information

You can review more information about each PLOG data set. This information can help you determine whether you want to replay records from the data set and whether or not you want to remove the PLOG data set entry from the list of PLOG data sets in the Replicator system file.

Start of instruction setTo review more information about a PLOG data set:

  1. Access the list of PLOG data sets from which replay processing can be requested, as described in Listing the PLOG Data Sets.

  2. Locate the PLOG data set for which you want more information, type an "I" in the corresponding Replay column, and press Enter.

    The Replication Replay - PLOG Information screen appears.

    End Date and Time The date and time of the last transaction in the PLOG data set.
    PLOG Session Number The number of the PLOG session for this PLOG data set.
    From Block Number The starting block number in this PLOG data set.
    To Block Number The ending block number in this PLOG data set.
    Last PLOG in session Indicates whether or not the PLOG data set is the last PLOG data set in the session. A value of "Y" in this field indicates that it is the last PLOG data set in the session; a value of "N" indicates that it is not the last PLOG data set in the session.

Deleting PLOG Data Set Entries From the List

You may find it useful to delete PLOG data set entries from the list of PLOG data sets -- especially if the list gets too long and the Replicator system file starts to fill up. For example, very old PLOG data sets appearing in the list may no longer be of use to you. In this case, you can use this screen to remove their entries from the list.

Notes:

  1. When you delete a PLOG data set entry from the list, all earlier PLOG data set entries are also deleted.
  2. When you delete a PLOG data set entry from the list, the PLOG data set still exists. Only its entry in the Replicator system file is deleted.

Start of instruction setTo delete PLOG data set entries from the list of PLOG data sets:

  1. Access the list of PLOG data sets from which replay processing can be requested, as described in Listing the PLOG Data Sets.

  2. Locate the latest PLOG data set entry you want to delete, type a "D" in the corresponding Replay column, and press Enter.

    The PLOG data set entry and all earlier PLOG data set entries are removed from the list.
