Migration of Ops Center analytics

Hello All,

 

We are in process of migration of our Ops Center analytics from Solaris Server to newly built VM on Linux OS.

In past we were having some issue related to low memory on our existing ops center server and we decided to build a new VM and migrate the ops center to newly created VM.

 

I had couple of doubts to perform this migration, below are the steps that i had prepared to follow the migrartion.

1) Take the backup of Ops Center using DB backup script

2) Built the new VM and install the ops center server software and patch it to old ops center server version

3) Perform the restore using the dbbackup script by prefexing "restore switch"

Below are my doubts.

a) Due to some internal organization process we cannot give the same name to newly created VM. We will built a new VM  by another name, but we can give it the Canonical Name as the old ops center name.

b) How many mount points we will need to create in New VM.

    A new name is fine - it doesnt need to have the same name

    I use this approach

    1. Install new one and patch to same level as old

    2. shut down old and new (opsadmin stop)

    3. move database files on new one to a safe place

    4. copy database files from old one to new one

    5. add new one as an opscenter server in master host properties (should need a re-start of NBU on master here really)

    6. start up new one

    That should all work unless you used any domain authentication on the old one which will need the authorisation exporting / importing too

    Is your old Solaris based OpsCenter Server on Solaris SPARC or on Solaris x64 ?

    .

    Chaps does it matter that Solaris SPARC is big-endian and Linux is little-endian?  Can a set of OpsCenter database files be copied between different 'endian' architectures?

    I think Mark was implying to copy the DB backup, not the actual files. If not, then that is what should be done.

    Thanks Mark for detailed step by Step instruction for migration of ops center to new VM.

     

    It would be great if you can give me the ports that needs to be opened between new ops center and Master servers, also how much directory size we would be requiring on our new VM (Considering our ops Center DB is of 18 GB).

     

    Thanks

    If you take a look at the OpsCenter Admin Guide there is a section outlining all ports used, along with a diagram of how it all fits together .. go to the "About communication and firewall considerations" section

    The sizing depends on how you want to use it. As you have analytics it could grow very large .. i am surprised it is only 18GB but perhaps your pruning is set fairly low

    The "About designing your OpsCenter Server" section in the guide givs a few ideas but it is very much down to what you want it to do and how long you want to keep the data.

    To clarify the copy part .... 

    On Windows you can actually copy all of the files held within the Program Files\Symantec\OpsCenter\server\db\data\ directory from the old to the new server.

    On *nix of the same type you can do the same (via the appropriate paths)

    On different O/S type where a simple file copy is not possible then the db backup and restore option can be used ... note in this case you would leave the original database files in place and just make a copy of them "just in case"

    This dbbackup method has even been used to move from Windows to Linux so should be fine for Solaris to Linux
