Updating Midserver URL/Instance Rename

[jonathan_77]

Hey all, 

We just changed our DEV instance URL name.  Following the instructions on KB0550841, it states:

"When using MID server note that you will have to change the MID Server configuration to have the MID to point to the new Instance URL."

I am attempting to update the Value field under "MID Server Configuration Parameter" from within ServiceNow.  When I I update the URL to reflect the new name and click save/update, I  am getting an error:  

Error Message

You are attempting to add or modify a read-only parameter -- not allowed

Error Message

Invalid update

Any suggestions on what I am doing wrong?  Do I need to sign onto the actual server that the Midserver was installed on and make the change from there?

Thanks,

Jonathan

Hello,

Whenever it happened to me, I've always logged into the server to reconfigure the config.xml file.

got to config.xml 
===========
for URL verify :

<parameter name="url" value=

check the username and password:
<parameter name="mid.instance.username" value="xyz"/>
<parameter name="mid.instance.password" secure="true" value="encrypted:test"/>

Check the sys_id also if it is changed to new value:

<parameter name="mid_sys_id" value=

Thanks,

Thanks!

I changed the URL in the config file and it has not updated the midserver configuration parameters??  Any other suggestions on what I need to do?

Thanks,
