We have done this before and I did this again today. At the moment there
are no biblionumbers existing in table "deletedbiblio" that also exist
in table "biblio". Menu "About Koha > System information" does not show
errors anymore.

I have checked the currentauto_increment values for all tables, the
values in the normal tables are always higher than the ones in the
respective deleted tables:
147200 - biblio
146933 - deletedbiblio
147200 - biblio_metadata
68588 - deletedbiblio_metadata
147200 - biblioitems
NULL - deletedbiblioitems
73229 - items
NULL - deleteditems
So if I understand right with this setup when using MariaDB 10.5.15 the
problem should no more happen.
Unfortunately I'm quite sure it will happen again anyway (as before). I
will then write to the list again.
PS: This is the 3rd trial to get this e-mail through.
Best wishes: Michael

Onderwerp: [Koha] DBMS auto increment fix not working
Hi
In our library we are using Debian 11 with MariaDB 10.5.15 and Koha
21.05.14.
When deleting bibliographic records in the staff client, some deletions
produce the message: "An error has occurred! Error 500 / This message
may have been caused by any of the following reasons: etc." In such
cases Koha menu "About Koha > System information" shows the message
aubout data problems, saying
Some of your tables have problems with their auto_increment values
which may lead to data loss.
You should not ignore this warning.
The problem is that InnoDB does not keep auto_increment across SQL
server restarts (it is only set in memory). So on server startup the
auto_increment values are set to max(table.id)+1.
To know how to avoid this problem see the related wiki page: DBMS auto
increment fix
According to
https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.koha-community.org%2Fwiki%2FDBMS_auto_increment_fix&data=05%7C01%7Cm.de.rooy%40rijksmuseum.nl%7C5c1a779522df4601c58808da8678d0b4%7C635b05eb66c748e1a94fb4b05a1b058b%7C0%7C0%7C637970150719835805%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=5BkXPF4yrrhvuLP1nFx66eQITkFCQPhoGPDtsdCDWso%3D&reserved=0
the problem
shouldn't appear with MariaDB 10.5.15 but as a trial we have implemented
the solution described there and have restarted everything - still the
problem persists.
In such cases file "plack-error.log" shows the following:
{UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate entry
'6187-marcxml-MARC21' for key 'deletedbiblio_metadata_uniq_key' [for
Statement "
INSERT INTO deletedbiblio_metadata (biblionumber,
format, `schema`, metadata)
SELECT biblionumber, format, `schema`, metadata FROM
biblio_metadata WHERE biblionumber=?
"] at /usr/share/koha/lib/C4/Biblio.pm line 2907
I suspect this behavior indeed looks like the original auto_increment
problem described in bugs 18242, 18651, 18966, 19106 and 20271 but the
reason may in fact not be the same since the described problem shouldn't
appear at all in MariaDB 10.5.15.
Does anyone have an idea what is happening and how we can solve it?
Best wishes: Michael
