Testing the replica
Testing p4 pull
To confirm that the p4 pull
commands (specified in the
Replica1
startup.N
configurations) are
running, issue the following command:
$ p4 -u super -p replica:22222 monitor show -a
18835 R service00:04:46 pull -i 1
18836 R service00:04:46 pull -u -i 1
18837 R service00:04:46 pull -u -i 1
18926 R super 00:00:00 monitor show -a
If you need to stop replication for any reason, use the p4
monitor terminate
command:
$ p4 -u super -p replica:22222 monitor terminate 18837 process '18837' marked for termination
To restart replication, either restart the Helix server process, or manually restart the replication command:
$ p4 -u super -p replica:22222 pull -u -i 1
If the p4 pull
and/or p4 pull -u
processes are terminated, read-only commands continue to work for
replica users as long as the replica server’s p4d
is
running.
Testing file replication
Create a new file under your workspace view:
$ echo "hello world" > myfile
Mark the file for add:
$ p4 -p master:11111 add myfile
And submit the file:
$ p4 -p master:11111 submit -d "testing replication"
Wait a few seconds for the pull commands on the replica to run, then check the replica for the replicated file:
$ p4 -p replica:22222 print //depot/myfile
//depot/myfile#1 - add change 1 (text)
hello world
If a file transfer is interrupted for any reason, and a versioned file is not present when requested by a user, the replica server silently retrieves the file from the master.
Verifying the replica
When you copied the versioned files from the master server to the
replica server, you relied on the operating system to transfer the files.
To determine whether data was corrupted in the process, run p4
verify
on the replica server:
$ p4 verify //...
Any errors that are present on the replica but not on the master indicate corruption of the data in transit or while being written to disk during the original copy operation.
Run p4 verify
on
a regular basis because any server’s storage is vulnerable to corruption.
