2631.0. "Polling Failures" by NEWPRT::SCHOOLER_CH (Cheap? thrill...Jump a horse) Wed Mar 25 1992 21:41

With 1.2.15 on a VAX6610, I am getting poll failures when using the Historian
FM.  Last poll failure reason is:  MCC specialized exception code: 335. 
Polling interval is 02:00.00 and the entity partion is "*".
Anyone have any idea what this is or where it may be documented.  As always
any help is appreciated.

2631.1how to translate exception codeTOOK::SHMUYLOVICHThu Mar 26 1992 09:4847
What do you mean by "entity partition is "*""? Show Recording gives you 
information for every partition which has a recording requests.

What entity are you polling? 

The specialized exception is on per entity per verb basis.

Assuming that you are polling node4 specialized exception 335 means 
"Node could not open required file".
This usually happens when you do "Show Initial Attributes" and don't 
have privileges to read permanent database.

Try the following:


MCC> show <your_entity> all <partition_which_gives_you_problem>

I think that you will see something like this:

Node could not open required file: Permanent Database.
                                   File = Permanent Database,
                   System Error Message = "%NML-E-OPENIN, error opening SYS$COMMON:[SYSEXE]NETNODE_LOCAL.DAT; as input
                                          -RMS-E-FNF, file not found"

The future release of Historian will translate exception code into readable
message. In v1.2 the user has two possibilities to find out the meaning of the
exception reported by the Show Recording/Exporting command:

	1. specify the corresponding Show command from MCC

          MCC> show <your_entity> all <partition_which_gives_you_problem>

	2. use DAP utility:
	   
	  a. for specialized exception:

	      DAP> show class <your_entity_class> directive show -
              _DAP>exception code <code-of_exception> definition reply_text

	  b. for common exception:

	      DAP> show class common directive common -
              _DAP>exception code <code-of_exception> definition reply_text
