Hi Jozef,

short answer: No.

We currently have the two agents SAPInstance and SAPDatabase. But both are 
not valid to manage a SAP LiveCache.
If you don't want to monitor the LiveCache, I would suggest to include the 
LiveCache start/stop commands to the USEREXITS of the SAP Central Instance 
(if in the same resource group).
Monitoring would need a new resource agent, because LiveCache needs a 
complete different command set, than all the other SAP things. Currently I 
don't know, if it is important enough for many people.

I would expect SAP to support LiveCache in the future with saphostctrl. I 
have prepared (for already a long time ) the changes to the SAPDatabase RA 
to work with saphostctrl. But not yet posted, because I'm still missing 
some features in saphostctrl to use it really as a HA tool.
If both would be the case, you may be able in the future to use 
SAPDatabase for LiveCache (including monitoring).

Best regards,
Alex
