18.5.10.21 The ndbinfo restart_info Table

The restart_info table contains information about node restart operations. Each entry in the table corresponds to a node restart status report in real time from a data node with the given node ID. Only the most recent report for any given node is shown.

The following table provides information about the columns in the restart_info table. For each column, the table shows the name, data type, and a brief description. Additional information can be found in the notes following the table.

Table 18.356 Columns of the restart_info table

Column Name Type Description
node_id integer Node ID in the cluster
node_restart_status VARCHAR(256) Node status; see text for values. Each of these corresponds to a possible value of node_restart_status_int.
node_restart_status_int integer Node status code; see text for values.
secs_to_complete_node_failure integer Time in seconds to complete node failure handling
secs_to_allocate_node_id integer Time in seconds from node failure completion to allocation of node ID
secs_to_include_in_heartbeat_protocol integer Time in seconds from allocation of node ID to inclusion in heartbeat protocol
secs_until_wait_for_ndbcntr_master integer Time in seconds from being included in heartbeat protocol until waiting for NDBCNTR master began
secs_wait_for_ndbcntr_master integer Time in seconds spent waiting to be accepted by NDBCNTR master for starting
secs_to_get_start_permitted integer Time in seconds elapsed from receiving of permission for start from master until all nodes have accepted start of this node
secs_to_wait_for_lcp_for_copy_meta_data integer Time in seconds spent waiting for LCP completion before copying meta data
secs_to_copy_meta_data integer Time in seconds required to copy metadata from master to newly starting node
secs_to_include_node integer Time in seconds waited for GCP and inclusion of all nodes into protocols
secs_starting_node_to_request_local_recovery integer Time in seconds that the node just starting spent waiting to request local recovery
secs_for_local_recovery integer Time in seconds required for local recovery by node just starting
secs_restore_fragments integer Time in seconds required to restore fragments from LCP files
secs_undo_disk_data integer Time in seconds required to execute undo log on disk data part of records
secs_exec_redo_log integer Time in seconds required to execute redo log on all restored fragments
secs_index_rebuild integer Time in seconds required to rebuild indexes on restored fragments
secs_to_synchronize_starting_node integer Time in seconds required to synchronize starting node from live nodes
secs_wait_lcp_for_restart integer Time in seconds required for LCP start and completion before restart was completed
secs_wait_subscription_handover integer Time in seconds spent waiting for handover of replication subscriptions
total_restart_secs integer Total number of seconds from node failure until node is started again

Defined values for node_restart_status_int and corresponding status names and messages (node_restart_status) are shown in the following table:

Table 18.357 Status codes and messages used in the restart_info table

Column Name Type Description
0 ALLOCATED_NODE_ID Allocated node id
1 INCLUDED_IN_HB_PROTOCOL Included in heartbeat protocol
2 NDBCNTR_START_WAIT Wait for NDBCNTR master to permit us to start
3 NDBCNTR_STARTED NDBCNTR master permitted us to start
4 START_PERMITTED All nodes permitted us to start
5 WAIT_LCP_TO_COPY_DICT Wait for LCP completion to start copying metadata
6 COPY_DICT_TO_STARTING_NODE Copying metadata to starting node
7 INCLUDE_NODE_IN_LCP_AND_GCP Include node in LCP and GCP protocols
8 LOCAL_RECOVERY_STARTED Restore fragments ongoing
9 COPY_FRAGMENTS_STARTED Synchronizing starting node with live nodes
10 WAIT_LCP_FOR_RESTART Wait for LCP to ensure durability
11 WAIT_SUMA_HANDOVER Wait for handover of subscriptions
12 RESTART_COMPLETED Restart completed
13 NODE_FAILED Node failed, failure handling in progress
14 NODE_FAILURE_COMPLETED Node failure handling completed
15 NODE_GETTING_PERMIT All nodes permitted us to start
16 NODE_GETTING_INCLUDED Include node in LCP and GCP protocols
17 NODE_GETTING_SYNCHED Synchronizing starting node with live nodes
18 NODE_GETTING_LCP_WAITED [none]
19 NODE_ACTIVE Restart completed
20 NOT_DEFINED_IN_CLUSTER [none]
21 NODE_NOT_RESTARTED_YET Initial state

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.

The restart_info table was added in NDB 7.4.2.
