ERDAS Apollo Application pool is not starting in IIS

Hi Team,

 

Greetigns for the day,

 

We have deployed ERDAS Apollo 2015 on Windows server R2 Standard with  H/w Configuration of 16 cores with 128GB RAM.

No of images (ECWS): Total number of images are serving around 120 images 

No. of Concurrent users: Currently 400 and going to be expected to increase to 500+ 

Approximate size of the images after compressing around 200MB to 20GB

 

ISSUE:

In IIS Manager, ERDAS Apollo Application pool is not starting itself we are starting it manually on everyday. Remaining all other application pools are starting itself. Kindly do the needful.

 

There are no errors recorded in the log file!!!

No sure why you have two application pools for Apollo essential?
"ERDAS APOLLO Essential ADMDP" doesn't look like the one created by Apollo.

Re: ERDAS Apollo Application pool is not starting in IIS

Thanks for the reply Haiyan,

 

We have created the new application pool for serving the imageries (around 120 Different satellite images) and now this application pool ("ERDAS APOLLO Essential ADMDP") stopping on irregular intervals!

 

Do we need to serve the images through default application pool to avoid this issue?

 

Anticipating more discussion from other members.

 

Cheers

Re: ERDAS Apollo Application pool is not starting in IIS

You can run Apollo from any application pool, as long as the Application pool is configured properly.

Does Apollo run properly from the standard Application Pool? If it does, compare the configuration of the new application pool with the origial one created by the installer.

 

You will find the reason it is stopping in the Apollo Log

C:\Program Files\Hexagon\ERDAS APOLLO\log\APOLLOCore.log or C:\Program Files\Hexagon\ERDAS APOLLO\log\APOLLOEssentials.log

 

or if IIS is killing your new application pool you should find the reason in the Windows Event Viewer (Rapid Fail Protection can do this).

 

 

If you still cant figure out why it is not working and the Installer created Application Pool works, you may want to switch it back.

 

 

I hope this helps.

 

Regards,

Phil
