# This test evaluates both recovery policies on when a member should become
|
|
# online.
|
|
#
|
|
# Test:
|
|
# 0. The test requires two servers.
|
|
#
|
|
# Phase 1: Recovery only waits for the certification of all cached transactions
|
|
# 1. Create 2 tables (t1,t2) on both servers
|
|
# 2. Start group replication on server1 with some data inserted on t1
|
|
# 3. Lock table t1 on server 2 and start group replication
|
|
# Recovery will get stuck as the member can't execute data on t1
|
|
# 4. Lock table t2 on server 2 and insert some data on t2 on server 1
|
|
# Recovery application of cached data is blocked as t2 is locked
|
|
# 5. Unlock t1 and recovery first phase will unblock.
|
|
# The member should become online as it does not wait for the application
|
|
# of cached transactions, only its certification.
|
|
# 6. Clean up.
|
|
#
|
|
# Phase 2: Recovery waits for the execution of all executed transactions
|
|
# 1. Create 2 tables (t1,t2) on both servers
|
|
# 2. Start group replication on server1 with some data inserted on t1
|
|
# 3. Lock table t1 on server 2 and start group replication
|
|
# Recovery will get stuck as the member can't execute data on t1
|
|
# 4. Lock table t2 on server 2 and insert some data on t2 on server 1
|
|
# Recovery application of cached data is blocked as t2 is locked
|
|
# 5. Unlock t1 and recovery first phase will unblock.
|
|
# The member should still be on recovery as the server is waiting for the
|
|
# execution of cached transactions and t2 is locked.
|
|
# 6. Unlock t2 and the application of cached transactions will unblock.
|
|
# The member should become online.
|
|
# 7. Clean up.
