• Database Location—Select the location of the database server from the list, local host or other
server.
• Database Server Address—Enter the IP address of the database server. This field is editable only
when other server is selected as the database location.
• Listening Port—Enter the listening port of the database server. The default is 1433.
• Installation Location—Enter or browse to the local directory where the IMC installation package is
stored.
• Data File Location—Enter or browse to the local or remote directory where the database files are
stored. If a remote database server is used, make sure the directory exists on the database server.
Envcheck verifies read and write access to this directory.
• HTTP Port—Enter the HTTP port number for IMC's webserver.
• HTTPS Port—Enter the HTTPS port number for IMC's webserver.
Superuser account
IMC installation requires a superuser account. You can use the default superuser account sa (for SQL
Server) or another account who has the superuser privileges.
IMC uses this superuser account to create database files and user accounts for IMC Platform
subcomponents and service components during deployment. After deployment, IMC Platform
subcomponents and service components use their respective user accounts for database access, instead
of the superuser account.
If the password of the superuser account changes after IMC deployment, update the password by
clicking Change Password on the Environment tab of the Intelligent Deployment Monitoring Agent.
Otherwise, you cannot view database information on the Environment tab, deploy new components, or
update existing components.
Setting the system time
H3C recommends the following settings:
• Set the time zone to GMT or Coordinated Universal Time.
• Do not enable seasonal time adjustments such as daylight savings time.
• Before installing IMC, check that the system time, date, and time zone settings on the server are
correct.
• When deploying IMC in distributed mode, make sure the time zone settings of all servers are the
same.
• Use the Network Time Protocol (NTP) to synchronize the time on all servers.
After IMC is started, do not modify the system time of the server; otherwise, intermittent problems can
occur such as:
• When jumping to a future time, the system can take a long time to process a large amount of data.
It can exceed the maximum time that the data can be saved in the database.
This affects the current data sampling speed and results in delay. After the processing of such data
is complete, the delay is gradually recovered.
