################################################################################ # Validate that XA transactions do work on Group Replication. # # Test: # 0. The test requires two servers: M1 and M2. # 1. With both the members ONLINE. Create a table on M1. # 2. Execute a XA transaction that does commit on M1. # - Verify GTID_EXECUTED and data in table on M1. # - Verify GTID_EXECUTED and data in table on M2. # 3. Execute a XA transaction that does rollback. # - Verify GTID_EXECUTED and data in table on M1. # - Verify GTID_EXECUTED and data in table on M2. # 4. Clean up. ################################################################################ --source ../inc/have_group_replication_plugin.inc --source ../inc/group_replication.inc --echo --echo ############################################################ --echo # 1.
