Extending space on a mount point in Virtual Machine

[baig]

Dear Erman,

how are you? hope you are fine.

My Environment :
single node DB : 12.1.0.2 ,
Applications primary node (virtualized) and DMZ node.
Version: R12.2.4

The mount point on which primary applications are installed is almost full. And as per our OS team it cannot be extended as it is a VM.

Can you please advise how to resolve this scenario.

Thanks in advance for your usual support.

Hi Baig,

thanks I m fine.

What mount point is that? Which server is it mounted on?
Please send me a "df -h" output.

What is the virtualization solution used there? OVM, KVM or Vmware? Also, why can't your OS team extend the size?

Also , you can analyze the apps filesystem and find somefiles to be deleted or archived.. This way, you may decrease your footprint..
You may also have a root reserve, and you may consider removing it.. This move can also make you gain some free space on that mount.. (if that mount is not used by root programs...)

Hi,

What mount point is that? Which server is it mounted on?
= The application binaries are installed on the mount point.  Application Server is mounted on it.


Please send me a "df -h" output.

==OVM is used. they say because its a VM specific mount point size cannot be extended but a new mount point can be added.

Thanks

OVM disks can be extended.. You will resize it and then extend the fs..
I suggest you to make a good search for this.. This can be done..

Also, as I said earlier;

You can analyze the apps filesystem and find somefiles to be deleted or archived.. This way, you may decrease your footprint..
You may also have a root reserve, and you may consider removing it.. This move can also make you gain some free space on that mount.. (if that mount is not used by root programs...)
