Re: [Sblim-devel] Copying huge size files from Provider to client

[Chris B. <buc...@li...>]

Hi Arun,

SFCB does not provide a method for log file retrieval.

To do it via the CIM interface, you would need to have a provider with 
that functionality. You may be able to use HTTP chunking to reduce the 
size of the buffers SFCB creates when returning data. The chunking 
feature is enabled by default for SFCB, but the request needs to send 
"TE: Trailers" as an HTTP header for SFCB to chunk the response.

Another way to to this (if you have a provider that supports it) is to 
issue an ExecQuery request to return a subset of the log file lines (for 
example, all the log lines for a given date). Alternatively if EQ 
requests aren't supported, issue a lot of GetInstanceRequests for 
RecordInLog (or whatever class is relevant to the log file).
