# WL9426: MySQL NG: Single Primary Mode in Group Replication
|
|
# Test SECONDARY(RO) fails gracefully upon executing DDL/DML via mysqlbinlog.
|
|
#
|
|
# Test:
|
|
# 0. This test requires three servers.
|
|
# 1. Bootstrap start GR on server3 (Primary).
|
|
# - Execute some transactions.
|
|
# - Stop GR on server3.
|
|
# - Save mysqlbinlog output in a file.
|
|
# 2. Bootstrap start GR on server1 (Primary). Start GR on server2 (Secondary).
|
|
# 3. Try executing mysqlbinlog output of server3 on server2(RO). Expect Error.
|
|
# 4. Try executing mysqlbinlog output of server3 on server1(RW). Expect Success.
|
|
# 5. Join server3 to the group.
|
|
# 6. Cleanup.
