Re: vvr

You don't need to stop the replication to swap the roles.

I'd normally use the vradmin migrate command to swap the roles, it does wait until the SRL is synchronised before swapping the roles. Otherwise you can use vradmin takeover if you understand what are you doing, because this can lead to some data loss if there are outstanding writes in the SRL

Re: vvr

hi,

when do i need to use the commands i specified?

tnx

Re: vvr

Stoprvg will stop replication, which I think is self-explanatory?

 

Re: vvr

hi,

yes it is self explanatory but i think those commands are used when you need to break the connection between the rvg in primary and rvg in secondary.Pimary rvg will carries on with normal work and secondary is used to test things.right?

tnx
