Impact of MC Service Guard on Performance

[Ramesh.K.R.]

Hi,

We are using different versions of MC Service Guard(for example 11.08 & 11.12). Does the diffrence in version cause any performance variations on supported applications.(i.e. the applications running HA using MCSG)

Thanks in advance,
Regards,

There should be no performance issues from using the different versions of MCSG, but there may be issues with compatibility of options in the event of a failover being carried out. Having different versions is only considered "correct" when you are performing a rolling upgrade of the software.

Hi,

There is no difference in the operations & everything is working fine. The customer had some apprehensions about the impact on performance during load test etc. Otherwise, everything is fine.
So, i can take it from you that there will not be any impact on performance ??

Thanks & Regards,

Hi,

With 11.13 ( current ) you are able to create more packages defauld 60 and with patches 150. Per package you can create memory is reserved, but this parameter is tunable
MAX_CONFIGURED_PACKAGES 40

'top' reveals that Serviceguard uses barely any CPU time.

Vrijhoeven mentioned the one thing that could possible consume more system memory, and possible affecting performance, but simply upgrading from an older version of SG to a newer one without changing the MAX_CONFIGURED_PACKAGES parameter won't change performance
