引擎中不存在表 'mysql.transaction_registry' (1932)

Question

I am trying to backup a database using mysqldump but I got this error:

Trying to backup MySQL database... mysqldump: Couldn't execute 'show create table `transaction_registry`':
Table 'mysql.transaction_registry' doesn't exist in engine (1932)

the problem first were with innodb_index_stats & innodb_table_stats and followed the instructions and worked well but got another problem

I tried from these 1 - 2 , but still getting the same error, any ideas?

Answer 1

what I ended doing is like that:

Removed corrupted tables:
rm -rf /var/lib/mysql/mysql/transaction_registry.idb

Recreated the table:

CREATE TABLE transaction_registry (
transaction_id bigint(20) unsigned NOT NULL,
commit_id bigint(20) unsigned NOT NULL,
begin_timestamp timestamp(6) NOT NULL DEFAULT '0000-00-00 00:00:00.000000', 
commit_timestamp timestamp(6) NOT NULL DEFAULT '0000-00-00 00:00:00.000000', 
isolation_level enum('READ-UNCOMMITTED','READ-COMMITTED','REPEATABLE-READ','SERIALIZABLE') COLLATE utf8_bin NOT NULL, PRIMARY KEY (transaction_id), 
UNIQUE KEY commit_id (commit_id), KEY begin_timestamp (begin_timestamp), KEY commit_timestamp (commit_timestamp,transaction_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin STATS_PERSISTENT=0 ;
