Status numbers 0 through 12 apply on master nodes only; the remainder of those shown in the table apply to all restarting data nodes. Status numbers 13 and 14 define node failure states; 20 and 21 occur when no information about the restart of a given node is available. 

## 23.5.14.44 The ndbinfo server_locks Table 

See also Section 23.5.4, “Summary of NDB Cluster Start Phases” . 

The server_locks  table is similar in structure to the cluster_locks  table, and provides a subset of the information found in the latter table, but which is specific to the SQL node (MySQL server) where it resides. (The cluster_locks  table provides information about all locks in the cluster.) More precisely, server_locks  contains information about locks requested by threads belonging to the current mysqld instance, and serves as a companion table to server_operations . This may be useful for correlating locking patterns with specific MySQL user sessions, queries, or use cases. 

The server_locks  table contains the following columns: 

• mysql_connection_id 

MySQL connection ID 

• node_id 

ID of reporting node 

• block_instance 

ID of reporting LDM instance 

• tableid 

ID of table containing this row 

• fragmentid 

ID of fragment containing locked row 

• rowid 

ID of locked row 

• transid 

Transaction ID 

• mode 

Lock request mode
