Siebel IP19 Parameters - for SQL Server Host Name Change

Hi,

We have Siebel IP19.9 version with database MS SQL Server 2014.

If we change the SQL server host name, say example the SQL Server host name is earlier was

"vmsbldbd01" and this is changed to sqlsbldev.

Question:

1) How to i change the "Gateway Security Profile" in Siebel Management console to point to the new host name "sqlsbldev"?

Please refer screen shot.

2) Same is the case for "Enterprise Profile", how do change the "Microsoft SQL Server Host Name" from "vmsbldbd01" to "sqlsbldev"?

Please refer screen shot.

3) Is there any other place in Siebel i need to change the host name?

Thanks
