Should I make backups of the database?

Yes, You are responsible for making periodic backups of the database. It is important to note that you should not back up or restore individual tables but rather the database as a whole.


The BIMcollab space is not online

  1. Is IIS running?
    1. Check if the BIMcollab space is started. Do this in IIS.
    2. Check if the BIMcollab space Pool is running. Do this in the Windows task manager.
    3. Check if the BIMcollab MailDigestService is started. Do this in IIS.
    4. Check if the BIMcollab MailDigestService Pool is running. Do this in the task manager.
  2. Is the database server running?

  3. Is SMTP server running?

The BIMcollab space is very slow

There are a number of reasons why your BIMcollab space could be slow.
  1. Reason: The MailDigestService is not working or very slow.
    Solution: restart the MailDigestService in IIS.
  2. Reason: There is a very heavy task running on the server which uses all CPU and/or RAM. This task can be a BIMcollab task itself like import/export a huge amount of issue’s.
    Solution: wait until these tasks are finished and check again.
If you are still not able to identify the cause for the diminished performance then please contact BIMcollab support via support@bimcollab.com.

Users can't find or connect to the space

In most cases this is caused by the DNS server not correctly resolving the space name.

Note that there are several ways to resolve such issues.
A simple solution is to add the local IP address of the server into the hosts file on the local machines. In the case that users are unable to connect via a BCF Manager you should check if the BCF Manager service is running on the server. To check, please enter the following URL into a internet browser on the computer which cannot connect:
https://.bimcollab.com/ webservice-010302/kubusbcfservice.svc (* enter your space prefix here)
If the service is properly running, you should see a webpage as shown in the example below.
