The server refuses the requested statement because global transaction identifiers are disabled (GTID_MODE=OFF).
MySQL error 3062 ER_GTID_MODE_OFF appears when you try to run a GTID-dependent statement, such as START SLAVE or RESET MASTER, while GTID_MODE is OFF. Turn GTID_MODE to ON (or ON_PERMISSIVE) and retry the command to resolve the issue quickly.
ER_GTID_MODE_OFF
Error 3062 occurs when a statement that relies on global transaction identifiers (GTIDs) is executed while the server variable GTID_MODE is set to OFF. The server blocks the command to preserve replication consistency.
The error was introduced in MySQL 5.7.5 alongside GTID enhancements. Typical commands that trigger it are START SLAVE, RESET MASTER, and any statement that writes binary log events expecting GTID metadata.
The error arises immediately when the server parses a GTID-dependent statement and GTID_MODE is OFF. It can occur on standalone instances, primary servers, or replicas.
Because GTID-based replication requires unique transaction identifiers, MySQL enforces the check early to avoid inconsistent replication states.
Leaving the system in this state blocks replication setup, failover automation, and point-in-time recovery workflows. Production replicas will not start until GTIDs are enabled or the command is omitted.
Resolving the error restores replication health and protects against data divergence across nodes.
The primary cause is issuing a replication or binary-log maintenance command while GTID_MODE=OFF. This setting disables GTID generation and prevents MySQL from assigning unique identifiers to transactions.
Common situations include migrating an old server to GTID-based replication, cloning instances, or restoring from backups where GTID_MODE was never enabled.
Enable GTIDs on the server, restart if required, and rerun the blocked command. MySQL supports a rolling upgrade path that minimizes downtime.
If GTIDs are not desired, remove or rewrite the offending statement so it no longer depends on GTID metadata.
During replica setup, the START SLAVE command fails with error 3062. Enabling GTIDs in the my.cnf file and restarting the replica resolves the issue.
During log maintenance, RESET MASTER triggers the error. Temporarily switching GTID_MODE to ON_PERMISSIVE allows the operation to succeed without breaking existing non-GTID replication.
Standardize on GTID-based replication across all environments. Set GTID_MODE=ON from installation to prevent drift.
Automate configuration checks using Galaxy or other CI pipelines to validate GTID settings before running replication scripts.
Error 1782 ER_GTID_MODE_REQUIRES_BINLOG indicates that binary logging is disabled while GTIDs are requested. Enable log_bin to fix it.
Error 1780 ER_GTID_NEXT_TYPE_UNDEFINED_GROUP occurs when a wrong GTID_NEXT value is supplied. Set GTID_NEXT to AUTOMATIC before running normal transactions.
Fresh installations on older MySQL defaults or after disabling GTIDs for troubleshooting.
Primary runs GTIDs while the replica still starts with GTID_MODE=OFF, causing START SLAVE to fail.
Automation issues GTID-dependent commands before the ALTER INSTANCE statement that turns GTIDs on.
Occurs when GTID_MODE is ON but binary logging is disabled.
Raised when GTID_NEXT is set to a specific UUID not matching any known group.
Triggered by CREATE TABLE ... SELECT under GTID enforcement without row-based logging.
Yes - use the OFF_PERMISSIVE and ON_PERMISSIVE transition states, then set GTID_MODE=ON. A restart is only needed to make the change persistent.
The overhead is minimal for most workloads. Benchmark in staging if you run extremely high write throughput.
While not required, enabling GTIDs early simplifies future replication or point-in-time recovery setups.
