How do I install it?

• For IIS need to run Java Servlets
• Tomcat(free)
• ServletExec by New atlanta()
• Can be very difficult.
• Install is a learning experience
• Need administrative privileges
• ESRI install documentation poor
• ESRIs user forums are excellent.

5
Three Parts of ARCIMS

• Administrator- Used to manage ArcIMS
• Service is equivalent to a virtual directory in
  IIS
  
• AXL or MXD can be turned into a Service
• WARNING MXDs as a service do not work often
• Author- Used to design ARCIMS services
• Similar to ArcGIS
• Add data to AXL project
• Designer
• Create sites in IIS server

6
Administrator

• Start Stop Services
• Can stop individual services
• Add New service
• Launch Author/Designer
• Can Manage Multiple Servers
• Three types of Services
• Feature- TRUE GIS on web
• Image- Images of maps
• Metadata- Share GIS Metadata

7
MetaData in IMS?

• Data about the data
• Use GIS data more efficiently
• Metadata Explorer Included with ARCIMS

8
Designer

• Very limited version of ARCGIS
• Design contents of a Service
• If you can use ARCGIS 8.x you will have no
  trouble producing AXL files for use with IMS.
  
• DATA allowed
• Coverage
• Shape
• SDE data connection
• Can mix and match data sources in one Project
• Warning -Not recommended
• Works sometimes

9
Author

• Wizard
• Create new site under IIS
• www.us.com/Ims/index.html
• HTML or Java Viewer?
• HTML works always
• Java doesn't work well with IE
• HTML browser is very good
• Note Geomedias (Intergraph) has ActiveX plug-in
  that works better with IE. Competitor to IMS
  

10
How can I customize IMS?

• Extensions
• RouteMap (for routing)
• Site starters
• Written in ASP
• Fairly easy to customize
• Multiple free ones available
• ActiveX connector
• Tough to program but very versatile
• For advanced users
• Used to add IMS to other web site
• JavaScript to directly customize IMS

11
Part 2 ArcSDE

• ArcSDE
• Spatial Database Engine
• STORE GEOGRAPHIC DATA IN A RELATIONAL DATABASE!
• Transparent to user that data is in database.
• Uses
• GIS Gateway to relational databases
• Also can be used to manage data in databases
• Insert/ Delete etc

12
What databases can I use?

• Oracle
• SQL Server
• DB2
• Informix
• Spatial extension for DB2 AND Oracle also work
  with SDE

13
How do I install it?

• Latest version is 8.2.
• Big jumps between 8.x revisions so use current
• Wizard is very good
• Create user, database etc on SQL server easily.
• Program has no GUI.
• Command line OR ARCGIS to manipulate database

14
Database considerations

• One or many databases
• One database is easy to administer.
• Use many if
• you have lots of different data
• have lots of different users of the data.

15
Privileges Privileges

• SDE is VERY particular about permissions
• SDE user(s) MUST have some high level database
  permissions to work.
  
• If all else fails use administrator and take
  privileges away until you find the failure.
  
• Documentation on this is short but specific
• See configuration tuning guides-

16
TUNING SDE

• TUNING IS NOT OPTIONAL
• Big guides for each DBMS
• Small adjustments can yield 25 speed
  improvements with SDE
  
• SDE is STILL slow with LARGE coverage's (over
  300meg)
  
• DO NOT log more then a few users with same
  username. Read write log file is the same file
  
• Imagine having 20 people read write to same text
  file _at_ same time.

17
Connecting

• IN ARC CATALOG
• Database connectionAdd spatial database
  Connection
  
• User must have correct permissions
• Server ltl6
• Service Port 5151 default
• Database (optional)
• Account info
• TEST first
• Now you can READ from the data.

18
EDITING data in SDE database

• Must be versioned
• In Arc Catalog
• Open list of shapes in database
• Select a record (shape, coverage)
• Right click and set register as versioned
• What is versioning?
• Stores a backup while you edit so more then one
  person can edit same record at the same time.

19
IT DOESNT WORK

• Common issues with ESRI software
• There are BIG steps between 8.x and 8.2
• Make sure you use all the latest stuff
• ARCIMS 4.X will ONLY work with ArcSDE 8.2
• ArcGIS 8.X must line up with your 8.x of SDE or
  you could be in for trouble
  
• Next step is to check file/user permissions
• After that check ESRI user forum
• Next try and call a friend
• Call ESRI- dont bother e-mailing them
