Display Database Instance Name in the System Message

Question

Greetings,
I am looking for a way to display the database instance name on each page in the Application Builder. Using the System Message would work for me and I can hard code the instance name, but I was wondering if there is a variable that I can specify that will accomplish the same thing.
Thanks a lot,
Larry

Hi Tony,
I did find that plug-in during my investigation. Some of the plugins sound interesting but I hesitate to anything to the base APEX install since I am not sure if this will affect supportability from Oracle if something goes wrong later on. Do you know if these plug-ins can be installed/deinstalled without affecting the base APEX install? There is also something called ApexLib which looks interesting. Do people use this? Any idea if it is still supported? I checked the forums and noticed there is not much recent activity. I wonder if it has been abandoned.
Hi Ashish,
I do have the application displaying the current environment. I set it up using Page 0 as you suggested. It works great. In fact, I have set up an 'About' page that grabs information from the WWV_FLOWS table which will display information about the current application. Here is my query:
SELECT ALIAS
     , AUTHENTICATION
     , CREATED_BY
     , to_char(CREATED_ON,'mm/dd/yyyy hh24:mi:ss')
     , DATE_FORMAT
     , DISPLAY_ID
     , FLOW_VERSION
     , ID
     , LAST_UPDATED_BY
     , to_char(LAST_UPDATED_ON,'mm/dd/yyyy hh24:mi:ss')
     , NAME
     , OWNER
     , PUBLIC_USER
  FROM apex_040000.wwv_flows
where ID = :APP_ID;
select substr(global_name || '.' ,1,instr(global_name || '.' ,'.') -1)
  into :P999_DATABASE
from global_name;I use GLOBAL_NAME to get the database SID instead of v$instance so I don't have to grant special privileges on v$instance.
If you find a way to grab the database SID from a query and put it in the System Message field, please let me know. In the interim, I have hard coded this in the System Message field.
<span style="padding:10px 20px 10px 20px; font-weight:bolder ;font-size:1.2em; background:#D96E1C;color:white">Development: TheInstanceName</span>Not exactly what I want, but it will get the job done.
Thanks for all your help,
Larry
