Exercise 2: Adjust Tuning Parameters for Archive Management

Version 2

     

    Exercise 2 - Once you have viewed the videos on managing your archive files, change the appropriate tuning parameter for Auto Archiving to move auto-generated archive files to the E: drive. Then, force an archive shift to create a new primary archive in the new directory on the E: drive. Finally, move your other existing archives to the same location and be sure to register them with the PI Data Archive.

     

    The following tuning parameters are discussed in KB 3223OSI8 to be used to limit the amount of data and the number of threads for calls to the PI Archive from a single client to prevent heavy hitters or rogue consumers: ArcMaxCollect and Archive_MaxQueryExecutionSec.

     

    For the tuning parameters above, answer the following questions:

    • What is the purpose of this tuning parameter?
    • What are the defaults?
    • Under what conditions do you think you would have to alter the values?
    • What considerations would you have in resetting this?
