    Description:

    When the bib library tab_fix has a "UE_01 fix_doc_ref_1 Y" entry each item update generates a CAT L $$aBATCH-UPD …” field.  This is a problem with serial ISSUE items where a whole group of items can be updated at once, flooding the bib record with redundant CAT fields.

    Resolution:
    For each item update, if the field updated is one indexed in an xxx01 index, each update creates an xxx01 z07 indexing request. (Note: the Cataloging programs do *not* allow multiple z07's for the same bib record at the same time, but if ue_01 processes the z07 generated by the first item update, that z07 will be removed and the update of the second item *will* generate another z07, etc.) 


    If a 
     UE_01 fix_doc_ref_1 Y 
    line in present in tab_fix, each processing of a z07 will cause an update of the headings fields in the record. Each of these appears as a “CAT L $$aBATCH-UPD …” field. 

    Conduct the following test: 
    * stop the xxx01 ue_01 
    * update the item records 
    * restart the xxx01 ue_01 

    You *should* now find that just a single xxx01 z07 was created and the processing of that z07 has resulted in a single “CAT L $$aBATCH-UPD …” field being added to the record. 

    Assuming so, and if it's possible to cluster these serial item updates, then turning ue_01 off at the times they are occurring could be a permanent solution to this problem.

    If, however, they occur randomly throughout the day, a more complicated solution, such as the following, will need to be used:

    * Comment out the UE_01 fix_doc_ref_1 line in tab_fix  (while leaving INS fix_doc_ref_1 Y line alone). 
    * Create a local script to do the following: 

    1. On a daily basis, mine the ue_08 log file for any doc numbers that have appeared since the last time the script was run 

    2. Use that list of doc numbers as the input for print-03, giving an unaltered Aleph sequential snapshot 

    3. Use that Aleph sequential file as the input/input type with manage-37 applying the INS fix routine (which still includes fix_doc_ref_1 Y) 

    4. Compare the original print-03 output with the manage-37 output to find only the doc numbers that have been changed by fix_doc_ref_1 Y, e.g.: 
    -004207948 7001 L $$aGallo, Stefano 
    +004207948 7001 L $$aGallo, S.$$q(Stefano) 


    5. Feed that list of "changed" doc numbers back to manage-37, this time applying the INS fix routine to the database directly
