ARCSDE & ARCIMS Mr. David A. Perini

ARCIMS  Internet Mapping Server Distribute GIS information over the Internet Integrates with addition ESRI softwareESRI  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) Tomcat  ServletExec by New atlanta($)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 *Image courtesy of ESRI

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   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 IN A RELATIONAL DATABASE! STORE GEOGRAPHIC DATA IN A RELATIONAL DATABASE! Transparent to user that data is in 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…  *Image Courtesy of ESRI

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  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 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 ing them
