I am looking for validation of a procedure, Sorry if this is rudimentary, but I inherited this issue because our DBA flew the coop, and I got stuck holding the reigns.
We have an SQL 2012 installation with many instances. The default instance MSSQLSERVER has a TCP/IP protocol assignment for port 1433, the rest of the instances just have Dynamic ports assigned for TCP/IP.
We can connect just fine using the hostname\instancename with the default port of 1433
We have a vendor that is demanding a static port that connects to the specific instancename.
My inkling is to go to sql server configuration manager, drill down to SQL server network configuration, select protocols for {instancename}, select TCP/IP, IP addresses tab, and in the IP one setting change it:
FROM:
- Active: yes
- Enabled: no
- IP address: {ip address}
- TCP Dynamic Ports: 0
- TCP Port: null
To:
- Active: yes
- Enabled: yes
- IP address: {ip address}
- TCP Dynamic Ports: null
- TCP Port: 11433
I would like to know if this is 1) correct and 2) safe to do without impact to any other instances, some of these run very mission critical apps and I have to be sure I am not going to mess any of them up before making this change. BTW... I will verify that the choose port is not in use by any other processes.
Thanks in advance,
John R
