3266.0. "Copying a Ultrix MIR?" by AZUR::RECHT (Ancien enfant de choeur) Mon Jun 29 1992 13:32

My system manager has installed DECmcc T1.2 on an Ultrix V4.2A (Rev. 47) test
system (with DECdns).  It works fine for non-root users when 'other write' is
added to the files in /var/mcc .

However, I'd really like to have my own local copy of the files.
So far, I have been unable to find a procedure for doing this that works.
Has anyone tried it and succeeded?

First problem:  maybe I'm misinterpreting the English, but in the
release notes,

	- Section 3.9.1 says you can't copy these files in an ordinary
	way since they are sparse files.

	- Section 3.9.2 says you could copy the files if you wanted to,
	which would fill in the holes, thus wasting space, without 
        invalidating the file.  It then goes on to describe the mcc_ndbm 
        unload/load utility. 

Well, which is it, folks?

After verifying that simple copies don't work,  I then produced my own local
copies through the following process, including the dictionary.   The following
3 environment variables were defined:

	MCC_MIR_LOCATION=/usr/usrs/recht/mymcc
	MCC_NS_LOCATION=/usr/usrs/recht/mymcc
	MCC_ALARMS_LOCATION=/usr/usrs/recht/mymcc

mcc_ndbm -u /var/mcc/mcc_00.mcc_exp_attr012_pms x.x
mcc_ndbm -l x.x mymcc/mcc_00.mcc_exp_attr012_pms

mcc_ndbm -u /var/mcc/mcc_00.mcc_exp_inst012_pms x.x
mcc_ndbm -l x.x mymcc/mcc_00.mcc_exp_inst012_pms

mcc_ndbm -u /var/mcc/mcc_alarms_attribute_mir x.x
mcc_ndbm -l x.x mymcc/mcc_alarms_attribute_mir

mcc_ndbm -u /var/mcc/mcc_alarms_instance_mir x.x
mcc_ndbm -l x.x mymcc/mcc_alarms_instance_mir

mcc_ndbm -u /var/mcc/mcc_dns_att x.x
mcc_ndbm -l x.x mymcc/mcc_dns_att

mcc_ndbm -u /var/mcc/mcc_dns_ent x.x
mcc_ndbm -l x.x mymcc/mcc_dns_ent

# already done a while ago...
# mcc_fdictionary.dat

mcc_ndbm -u /var/mcc/mcc_mir_repo_table x.x
mcc_ndbm -l x.x mymcc/mcc_mir_repo_table

mcc_ndbm -u /var/mcc/mcc_pa_attributes.mir x.x
mcc_ndbm -l x.x mymcc/mcc_pa_attributes.mir

mcc_ndbm -u /var/mcc/mcc_pa_instance.mir x.x
mcc_ndbm -l x.x mymcc/mcc_pa_instance.mir

mcc_ndbm -u /var/mcc/mcc_target_data_mir x.x
mcc_ndbm -l x.x mymcc/mcc_target_data_mir

mcc_ndbm -u /var/mcc/mcc_target_inst_mir x.x
mcc_ndbm -l x.x mymcc/mcc_target_inst_mir

Under all circumstances the following error comes up.

> mcc
Can't open master repository table: No such file or directory
Waiting: MM mcc_notification_fm has not completed startup
Waiting: MM mcc_notification_fm has not completed startup
Waiting: MM mcc_notification_fm has not completed startup
	(ad infinitum)

Can anyone shed any light on this?  Thanks,

    I meant to say *without* DECdns.  Just local MIR files.

Section 3.9.2 is correct.

There are files called mcc_mir_repo_table.*
which point to the other repositories.  You may need to re-create this
file by re-enrolling a management module that creates a MIR (eg registration).

BTW, these environmental variables are intended for use by developers,
and may note be robust enough for users.
