################################################################################ # WL#6833: GCS Replication: Read-set free Certification # Module (DBSM Snapshot Isolation) # # Scenario 2: Replicate from a server into a group # # Verify Group Replication behavior when we establish a # asynchronous replication connection from a server to a group. # # Test: # 0. The test requires three servers: M1, M2 and M3. # 1. Bootstrap start a group on M1. Start GR on M2. # 2. Setup a asynchronous replication connection from M3 into group(M1) # i.e. M3 -> M1. # 3. Execute some transactions on M3. # 4. Wait until transactions executed on M3 are applied on group. # 5. Execute a transaction on the group(M1). # 6. Validate data on M3. # 8. Validate data on M1. GTID_EXECUTED on M1 must have GTID_EXECUTED from M3. # 9. Validate data on M2. GTID_EXECUTED on M2 must have GTID_EXECUTED from M3. # 10. Clean data. # 11. Stop asynchronous replication connection from M3 into group(M1). # 12. Stop Group Replication on M1 and M2. ################################################################################ --let $group_replication_group_name= 8a94f357-aab4-11df-86ab-c80aa9420000 --source ../inc/have_group_replication_plugin.inc --let $rpl_skip_group_replication_start= 1 --let $rpl_server_count= 3 --source ../inc/group_replication.inc --echo --echo ############################################################ --echo # 1.
