Thousands of Z07's created; p_manage_62 changes date in all z30 records

Description:
The queue of ABC01 Z07 records suddenly grew this morning from around 100 to more than 200,000. What might have caused this?

Resolution:
See SKB's 4093 and 8192-2743 for how to diagnose the source for z07's in the bib library. In this case, it was found that the source was abc50.

The abc50_p_manage_62.02381, running at 8:13 this morning, created the Z07s. It was submitted with the following parameters:

setenv p_active_library "ABC50"
setenv p_input_file ""
setenv p_adm_number_x "000000000"
setenv p_from_sublibrary ""
setenv p_to_sublibrary ""
setenv p_from_status ""
setenv p_to_status ""
setenv p_from_process_stat ""
setenv p_to_process_stat ""
setenv p_from_depository_id ""
setenv p_to_depository_id ""
setenv p_from_collection ""
setenv p_to_collection ""
setenv p_from_year ""
setenv p_to_year ""
setenv p_from_location ""
setenv p_to_location ""
setenv p_from_location_2 ""
setenv p_to_location_2 ""
setenv p_from_material ""
setenv p_to_material ""
setenv p_from_arrival_date "19000101"
setenv p_to_arrival_date "19000101"
setenv p_from_order_number ""
setenv p_to_order_number ""
setenv p_from_copy_seq_x ""
setenv p_to_copy_seq_x ""

The intention was to specify a particular input file. (SQL shows that there are no records with z30_arrival_date = '19000101'.) But the input file name was inadvertantly omitted.

The result, as shown by the following SQL, was that 436,000 z30's were given an update-date of 20070129 -- though no real change has been made to the record:

SQL> select count(*) from z30 where z30_update_date = '20070129';

**Please note that p_manage_62 will change the z30_update_date of any record which is in the input file to today's date. If no input file is specified, it will update the z30_update_date in *all* z30 records.**

Since the Z07s created by this p_manage_62 are of no real use (since no update occurred), the following SQL was used to delete them:

SQL> delete from Z07 where z07_history like "ABC50%' and z07_sequence like '20070129%';

Note: Though util c/1 didn't show any p_manage_62 process still running, "ps -ef | grep manage_62" did:

aleph 19730 1 6 08:13 ? 00:29:31 /exlibris/aleph/a18_1/aleph/exe/rts32 b_manage_62

That process needed to be killed.

And the ue_01 in the abc50 library *also* needed to be stopped (see step #2 in SKB 8192-2743) and the delete of the z07's done there.
