Reset the GeoServer
Occasionally the GeoServer instance will lockup due to being several versions out of date. To reset the GeoServer:
- Login to the machine EIS (DL OTT SC TFS Programs Apps Administrators group has access)
- Open the Services Panel
- Find GeoServerService and open it's Properties.
- Click Stop Service, wait for it to complete.
- Click Start Service, wait up to 30 minutes for the server to restart.
- Navigate to http://eis/ and select maps - if the Icons load correctly the server instance has been reset successfully.
You must uninstall the NuGet Package SlowCheetah in order for the application to compile.

History
- Initial Release : 2009
- Original code name was "Rose" or "Crimson".
- 3 Contracts over the course of 7-10 years, all awarded to "Esper Consulting" (now defunct)
- AMS was not responsible for EIS until around 2014~.
How Authentication Works
The way the EIS works with User Authentication is as follows:
- The Server demands Windows Authentication (either NTLM or Kerberos v5 – I’m not bothering with that low level of security implementation to identify which of the two it is.)
- The user responds with the info needed to prove the user is part of the TC Network.
- The EIS then checks the username is the correct size.
- The EIS then checks if an IMPERSONATE flag is set.
- The EIS then connects to the Oracle DB using a “proxy user” piggybacking off the “EISWeb” user. If it can retrieve the Build Number, it considers connection a success. Otherwise an error occurs.
- The users roles are then read by the EIS via the AC005_USER_ROLE table, and a dictionary of grants is created from the XML files realproperty.roles.xml, tank.system.roles.xml, environmental.protection.roles.xml, contaminatied.site.roles.xml, and application.roles.xml. Off of the following “role” types defined in the Oracle DB
- EIS_ADMIN, CONTACT_ADMIN, IMAGE_ADMIN, EDOC_ADMIN, NOTE_ADMIN, USER_ADMIN.
- CS_VIEWER
- EP_ADMIN, EP_UPDATER, EP_VIEWER, RP_ADMIN, RP_ADMIN_LL, RP_VIEWER
- TK_ADMIN, TK_UPDATER, TK_UPLINKER, TK_VIEWER
- The EIS then defines page access off these defined roles in the XML files based on each page (and some individual elements on the page) checking “PageLoadPermissions” a variable (that’s really more of a constant) on each page.
