When starting confluence service, an error about MySQL session isolation level was raised

YY哥 Community Leader Apr 29, 2022

This Exception is as follows:


MySQL session isolation level 'REPEATABLE-READ' is no longer supported. Session isolation level must be 'READ-COMMITTED'.


I know the resolution is as follows, but I don't know why the db config was changed. Could anyone to figure it out? Thanks.

-- 解决办法:
-- 查看InnoDB会话级别的事务隔离级别:
-- SELECT @@tx_isolation;
-- 修改事务隔离级别:
set global transaction isolation level read committed;
set session transaction isolation level read committed;

Hi @YY哥 ,

Welcome to Atlassian community. 

Yes, as rightly pointed out by @Nic Brough _Adaptavist_ you should change it to read-committed. Actually we have a detailed KB regarding the same. You can go through the below page.

I hope above info helps. Have a good weekend.!

I've run into this too, I managed to get away with swapping the database to read-committed.

If I were you, I would test that change to read-committed works
