We have successfully installed MCC 1.2.7 on Ultrix 4.2. We are getting the following error when doing a MANAGE ; register node4 frsold ... etc Fatal MIR I/O error... This case is specifically mentioned in the release notes as being related to the access rights granted on the files in the /var/mcc directory (page 3-6, section 3.7.1). We tried to follow the instructions given page 3-9 of the installation guide, which are supposed to alleviate this problem. These in- structions would not work exactly as written. Ultrix will not create a group called "mcc_users" using addgroup, but will print a message to the effect that this name is too long. We tried to get around this by creating a group named "mcc_user" which ULTRIX created. We then performed the change in group acc- ess rights mentioned in the above mantioned section, but this had no effect within MCC - the register command still failed with the same msg. We must be doing something wrong here as others have apparently installed and run MCC on ULTRIX. Any ideas? Also, I want to install INGRES on my Decstation, and want to remove ULTRIX/ SQL, which is effectively dead anyway. Will this cause any compatibility issues with MCC? The environment variables are the same for both products, but MCC may have its hooks buried deeper in ULTRIX/SQl than that.

You must stop all of your DECmcc processes (mcc_kill) and let them re-start after changing file protections. You may also need to log out and back in to make the new group effective. >Also, I want to install INGRES on my Decstation, and want to remove ULTRIX/ >SQL, which is effectively dead anyway.

We have not tested the exporter on ULTRIX with any database other than ULTRIX/SQL (the exporter is the only part of DECmcc that uses SQL or INGRES). However, I don't believe we are using any hidden interfaces, so it is likely to work. | |||||
