    Description:
    - There are 1,568,541 z309/circ logs are attached to the same patron
    - As a result: system performance slows down when we try to retrieve patron's information + system error pops up when click on the "Circulation log" link on the patron window.

     

    Resolution:  

    The article  "GUI Circulation Log maximum" ( https://knowledge.exlibrisgroup.com/Aleph/Knowledge_Articles/Recent_changes_not_showing_up_in_ARC/Item_shows_as_unavailable_in_Primo_--_even_after_reshelved/Like-item_logic/Hold_requests_slow_for_certain_serials_items/GUI_Circulation_Log_maximum ) describes a maximum of 64,000 z309's which can display in the GUI for a particular patron.

     

    The following article shows how to determine which z309 records cir-78 is not deleting:  "cir-78 is stalled" ( https://knowledge.exlibrisgroup.com/...-78_is_stalled )

     

    The following articles address the topic of deleting old z309 records....

     

    "v21/v22 cir-78 runs longer than previously, not removing z309 records it should"

     

     

     

     

    Additional Information

    The z309_rec_key is 27 bytes, consisting of the Z309-ID plus the Z309-SEQUENCE.

    The Z309-ID is the 12-byte patron ID and the Z309-SEQUENCE is 15 bytes, with the format yyyymmddnnnnnn.

    So there's a limit of 999,999 z309's per patron, per day -- but that's the only limit to the number of z309 records.
