Mapviewer/Oracle Maps Licensing

Due to Oracle's strategic change from the Oracle Application Server (OC4J) to the BEA Weblogic Server some questions came up re the licensing.
MapViewer is now also included in the WebLogic licenses.
It is also included in the TopLink/ADF standalone license for deployment on other supported J2EE servers (ie: other than WebLogic and Oracle Application Server).
Recap:
Following Software does include the Mapviewer/Oracle Maps:

• TopLink/ADF
• Weblogic Server Standard Edition
• Weblogic Server Enterprise Edition
• Weblogic Suite
• Internet Application Server Standard Edition One
• Internet Application Server Standard Edition
• Internet Application Server Enterprise Edition

for the pricelist suggest to check the Oracle Store or contact your Oracle Sales Rep.

online Geocoder

A forgotten Link to Oracle Spatial Geocoder is here.
And here is a JSP with a small demo page.
There one can see how the GEOCODER is queried and the result being printed out.
A good page to illustrate an SQL Query on Geo-Data !

Reverse Geocoding here (lower part) and usage of the XML Format here:

Give it a try !

Spatial Join = (German: Verschneiden)

One of the most important tasks of a GIS application is the "Spatial Join" or "das Verschneiden" (in German):



Oracle Maps may fully take advantage of the inbuilt Oracle Spatial Technology as part of the database. The functions ANYINTERACT and/or SDO_RELATE are used to calculate above e.g. which FOI (customer) is located in the Polygon (REGIERUNGSBEZIRK = County).
When you click ('mouse_click') on the polygon the Spatial Function is invoked and no timeconsuming calculations are carried out - and you have the result within a second.

SpatialDB Advisor

I today came across a very useful site/BLOG of Simon Greener, an "independent Spatial Advisor". I will add a link in my "Spatial BLOG's" - so if you like to "deepdive" into Spatial and/or GIS terminology and functions, procedures, tipps and tricks (and not only Oracle, but also MSql-Server, MySQl, PotGIS, etc.) you will find a lot of stuff on his site/BLOG "SPATIALDB-Advisor"
Good luck !

More Memory for the MapTileServer (Mapcache) !!

Especially when generating detailed tiles by the MapTileServerCache (Mapcache) in Oracle Maps the OC4J needs more Memory to be allocated !!
When you do start the Mapviewer without an explicit command to allocate Memory, only 128 MB will be assigned to the OC4J.
The side effect with too less memory: The MapTilServer will generate tiles, but these are just containing the background color and no details from the layers.

Now, when you like to generate the tiles (*) for the Mapcache (either during runtime, when the user interacts with the map or if you like to prefetch the tiles) the Mapviewer needs more Memory !
So I recommend to start the Mapviewer like:

C:\mv10131_qs\oc4j\j2ee\home>java -Xmx512M -jar oc4j.jar

and you can play around with the Xmx512M to increase like Xmx1024M when needed.
For standard operation 256 might be sufficient.
Parameters like ZoomLevel and tile-size are influencing the memory consumption (during generation!).

(*) the generated tiles are stored in the file system in a directory like:
C:\mv10131_qs\oc4j\j2ee\home\applications\mapviewer\web\tilecache\

and looks like:



Have fun !

Force Mapviewer to use the right JAVA directory

I recently again came across JAVA errors/exception referring to JSP's when starting the Mapviewer with Java exceptions.
The reason was, that the Mapviewer startup batchfile did not include the
SET JAVA= path.... and a JAVA runtime version cud not complie the respective JSP's.
I was able to access the Mapviewer ADMIN Page but some other pages seem to have gone (cud not be compiled properly during runtime)
To overcome this obstacle recommend to include the JAVA SET command as follows:
(my startup batchfile assigning 512 MB RAM to the OC4J(Mapviewer)


Good luck !

Oracle BI EE and Oracle Maps

I just came across this perfect Step-by-step description of the Integration of Oracle Maps in Oracle BI Suite.

Oracle MAPS-Workshop 14. Mai 08 in Darmstadt

Eine eigene „MAPS“-Anwendung im Intranet mit Kartendaten, Luftbildern und integrierten fachlichen Informationen?

Kein Problem – auf dieser InGeoForum-Veranstaltung am 14. Mai 2008 erfährt man, wie das geht.

Die Oracle Geodaten-Technologie kommt mehr und mehr bei Kunden und Partnern an. Als nächstes werden wir (Carsten Czarski) sie beim InGeoForum vorstellen - das InGeoForum dient der Information und Kooperation zwischen Anbietern und Nutzern von Geodaten, -Informationssystemen und -Dienstleistungen.
In der eintägigen Veranstaltung wird unter anderem vorgestellt, wie man eine Karte mit Oracle MAPS in 15 Minuten ins Internet oder Intranet bringen kann. Neben Oracle werden auch die Oracle Partner Mettenmeier und GDV den Einsatz unserer Technologie vorstellen.

Ein MUSS für jeden Kunden, der an Geodaten interessiert ist (und wer hat noch nie Google Maps genutzt?)

Oracle Maps und der JDeveloper 11g

Auch wenn ich nicht gerne Content produziere durch einfaches Verlinken, möchte ich meine Besucher und speziell JAVA Entwickler hier auf diese 2 neuen (Februar und März 2008) BLOG Beiträge von Andrejus Baranovski hinweisen:

1. Oracle Maps in JDeveloper 11g - Even More Simple (Febr. 2008)

2. Oracle Maps in JDeveloper 11g - Perfectly Fits into Enterprise (März 2008)

Mit Suchergebnis neben der Karte.

Beides beruht auf den neuen Visualisierungs-Komponenten des Oracle JDeveloper 11g - Technical Preview 3"out-of-the-Box".
