4689.0. "Help on HISTORIAN please" by STKHLM::BERGGREN (Nils Berggren EIS/Project dpmt, Sweden DTN 876-8287) Mon Mar 15 1993 06:11

Hi,

On the queue SYS$BATCH (owner=[SYSTEM]) the MCC_HISTORIAN_BACKGROUND 
is executing for the domain tvt-sverige.

If I (not logged in as SYSTEM) do a 

MCC> show recording Node4 MALEN part=counters, in domain tvt-sverige

I get Recording state = ACTIVE and all arguments about the recording.

If I try to start recording on another partition like:

MCC> record node4 malen partition = status, poll=0:5:0, -
	in domain tvt-sverige

I get "Background recording process for this domain is not set up"

How come?  

When I read in the Historical Data Services Use, DECmcc v1.3, 
page 1-8, it states that 

	"The uic parameter... The group number of this UIC must 
	be the same as the group number of the UIC assigned to 
	the domain."

This is not the case here, but I ask myself, why?

On the other hand, logged in as SYSTEM, I can start recording, even
though the domain's owner is myself (UIC group # 102).

If I can do a SHOW RECORDING, why can't I start recording?  Why the 
restriction on UIC-code.


Have I missed something here?

    In the Historian FM all polling operations are done in the Background
    process. So even if you see in the Show Recording command status = active
    data are not collected if the background process is not running.
    Because of this the Record command can not be successfully executed without
    background process.

    By the way, one of the arguments of the Show Recording command indicates
    that the Background process is not running:
 
        Last expiration failure reason = "Background recording process for this domain is not set up",
  
    The requirement for MCC process, Historian background process, and Domain 
    to be from the same UIC group came from security reasons: once recording 
    is set up only the user from the same group can delete/disable/modify it.

    Hope this helps,
