1954.0. "Fatal MIR I/O error" by RDGENG::PRATT () Mon Dec 16 1991 13:30

Whilst using graph to monitor npdu stats on a phaseV routing csmacd-0 circuit, 
the window I called the iconic map from logged the following errors...
 
Fatal MIR I/O error, repository=mcc_pa_instance.mir, errno=1
Fatal MIR I/O error, repository=mcc_pa_attributes.mir, errno=1
Fatal MIR I/O error, repository=mcc_pa_instance.mir, errno=1
Fatal MIR I/O error, repository=mcc_pa_attributes.mir, errno=1
Fatal MIR I/O error, repository=mcc_pa_instance.mir, errno=1
X Toolkit Warning: BadDrawable - parameter not a Pixmap or Window
Exception in Mgt Module (id=6), CMA code = 408184

I'm not sure if the last two errors were a result of doing something else, but I
have seen the Exception error a number of times.

Running risc T1.2.3  on a DS5200 32Mb and local NS.

1954.1You need write access to the MIRsRAMPAL::MINTZErik MintzMon Dec 16 1991 14:4128
Please fix the MIR protection, then we can see if the CMA error
is related or not.

From the release notes:

        3.7.1  DECmcc Local Instance Repository Files

        When using the local implementation of the Instance portion of the
        MIR, there are some special considerations.

        For non-root users to access the DECmcc Instance Repository, the
        repository files in /var/mcc must be made accessible.  otherwise,
        the error messages
 
            Fatal MIR I/O error, repository=mcc_dns_ent, errno=1

        and

            The requested operation cannot be completed

            MCC Routine Error = %MCC-E-IO_ERROR, error was returned by I/O
            facility

        will be received.

        See Section 3 of "Planning and Installation for ULTRIX" for
        information on changing access rights.
1954.2Cannot create domain - related problemRDGENG::PRATTTue Dec 17 1991 11:5435
Erik,

I fixed the access to the /var/mcc and I no longer get that error when using the
graph utility. What I cannot do though is to create a new domain from a non root
account - I still get the same error. I have created a group as the book says, and
even opened up the files to be world writable (chmod 777) but still it will not
work. What am I missing?

Is it possible that the domain FM was running at the time you changed
the repository protection?  If so, please stop all of your DECmcc
processes (use mcc_kill), and then try again.

1954.4Okay nowRDGENG::PRATTTue Dec 17 1991 12:467
Erik,

I killed all the mcc processes and restarted them, it now works correctly.

Thanks

Ian
