ARCSDE & ARCIMSMr. David A. Perini
ARCIMS Internet Mapping Server
Distribute GIS information over the Internet
Integrates with addition ESRI software ArcSDE, ArcGIS, ArcInfo, ArcMap etc…
Available Extensions Route map enables routing ($) Site starters (free)
Written in ASP (active server pages)
How do I install it? For IIS need to run Java Servlets
Tomcat(free) ServletExec by New atlanta($)
Can be very difficult. Install is a learning experience Need administrative privileges ESRI install documentation poor ESRI’s user forums are excellent.
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 MXD’s 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
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
MetaData in IMS? Data about the data
Use GIS data more efficiently
Metadata Explorer Included with ARCIMS

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”
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: Geomedia’s (Intergraph) has ActiveX plug-in that works better with IE. –Competitor to IMS
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
Part 2 :ArcSDE ArcSDE
Spatial Database Engine STORE GEOGRAPHIC DATA STORE GEOGRAPHIC DATA
IN A RELATIONAL IN A RELATIONAL DATABASE!DATABASE!
Transparent to user that data is Transparent to user that data is in database.in database.
Uses GIS Gateway to relational
databases Also can be used to manage
data in databases Insert/ Delete etc…

What databases can I use? Oracle SQL Server DB2 Informix Spatial extension for DB2 AND Oracle also
work with SDE
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
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.
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-
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 @ same time.
Connecting IN ARC CATALOG Database connection>Add spatial
database Connection
User must have correct permissions Server :ltl6 < our SDE server Service: Port # 5151 default Database (optional) Account info
TEST first Now you can READ from the data.
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.
IT DOESN’T 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- don’t bother e-mailing them
