Mapviewer caching on WMS and WFS

Does the tile cache do any good for WMS?
e.g.: only same result for same parameters like simple HTTP caching?
or can it do nice things like assembling cached tiles as required?
What about WFS caching? I assume every requests hits the database. Since moving the query window 5m to the left ... :-)
---

Just to be clear then, if someone is accessing my MapViewer instance using WMS i.e they are sending requests such as
http://host:7001/mapviewer/wms?REQUEST=GetMap&LAYERS=...
MapViewer does not cache these and will generate the map each time (even for identical consecutive requests). Is this correct?

Oracle MapViewer 12.1.3 and WFS-T (Transaction) Service

Hello,
I am new to Oracle MapViewer.
Does Oracle MapViewer 12.1.3 supports WFS-T (Transaction) Service similar to ArcGIS Server 10.2?
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
"WFS is a specification published by the Open Geospatial Consortium, Inc. (OGC), for serving geographic features on the Internet.
A WFS service with transactions (WFS-T) allows WFS clients to apply edits (inserts, deletes, and updates) to the data in the source database through the WFS service."

Hello,
I am also having a hard time to understand all the required software and installation process to create a simple WFS service, the documentation is not very clear.

10.3 Setting Up the Client for Spatial Web Services
Before anyone can use Spatial and Graph web services, you, as an administrator with the DBA role, must ensure that:
•The $ORACLE_HOME/md/jlib/sdows.ear file is deployed into an OC4J instance.
•The necessary database connections are defined (if you accepted the default location for the sdows.ear file deployment) in the <j2ee_home>/home/applications/sdows/META-INF/data-sources.xml file. This file defines database connections available for use with all web services, including OpenLS and WFS.
You should then examine and modify the <j2ee_home>/home/applications/sdows/sdows/WEB-INF/conf/WSConfig.xml file, which controls web services behavior. Example 10-1 shows the Oracle-supplied WSConfig.xml file, which you should modify as needed for your system environment. For more information about how to modify this and other files, see the Readme.txt file for the wsclient.jar demo file (described in Section 10.4, "Demo Files for Sample Java Client").
What do I need to install? How do I deploy OC4J? How I deploy this in Weblogic or Glassfish? How do I deploy the .ear file in OC4J?
I am a beginner and need more clear instructions .

But how I do the same in OC4J/Weblogic/Glassfish? and in 11gR2 and 12c?
Any help is appreciate.

Mapviewer serving out wms and cache

When I use openlayers and point to the wms from mapviewer, it is not using the cache. Is there a setting to make this possible?
Rob

I am not familiar with OpenLayers, but if you point to a WMS from Oracle Mapviewer you can define the WMS as an "external" Layer which is cached then....
Pls see my BLOG how to setup an external cache:
http://oracle-maps.blogspot.com/search?q=wms
(its in German, but you may get an indea from the screenshots)
Start with Mapviewer --> ADMIN --> "Manage MapTileLayers "(in 10.1.3.1) or "Manage Mapcache" (earlier) --> Create --> external --> etc.
Good Luck !

Mapviewer javabean, sessions, state and related

Hi,
i am a scratching my head a little bit regarding the way I use MapViewer.
We are building a web-app using a mapviewer for rendering the map, doing queries etc. We are using AJAX for user-interaction, including the map window, identifying objects, searches etc.
I have currently implemented a singleton class which holds one instance of MapViewer. This instance recieves parameters from the session, and then executes run();
However, since the MapViewer bean is stateful, and I want to make use of identify() etc, I realize that this is probably a wrong way of doing it ?
Would it me more appropriate to alloc a new MapViewer instance for each session ? And would this be a very memory-consuming way ?
kind regards,
Oyvind

Thanks, Andrejus.
I tried to do some memorytesting, with results:
100 instances:
com.powel.mapviewer.MapViewerFactory produced [Ljava.lang.Object; which took 1403184 bytes
1000 instances:
com.powel.mapviewer.MapViewerFactory produced [Ljava.lang.Object; which took 14086016 bytes
10000 instances:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
Seems like this is a memory-eating way of doing it, so I think I will try to create a pool of mapviewers instead.
Oracle Maps is an interesting feature, but in our case I believe it will complicate things (we dont want tiles, and we use WMS background etc)
Regards,
Oyvind

My iPhone 4s keeps showing more space being used for photos than i have - i have deleted cache folders, unselect and reselect in iTunes and nothing appears to work my iPhone still shows 6.5 gig use of photos when i only have the camera roll listed

my iPhone 4s keeps showing more space being used for photos than i have -
i have deleted cache folders, unselect and reselect in iTunes I read one post
where they said keep syncing and in a couple days it would correct itself, that
hasnt happened. I have see others have the same issue but no solution and nothing
appears to work my iPhone still shows 6.5 gig use of photos when i only have the camera roll listed

i thought the photo stream only holds 1000 i usuaaly take each month and save them to iphoto but if thats the my ipad should say the same amount and it doesnt - it shows 2.5 gig which is correct for iphoto. and i havent ever had that much but if for some reason icloud has that much saved how do i delete and again if it does why doesnt ipad show that amount _ HELP!

I used to be able to download a lot of cd's, now I cannot download more than one or two cd's at a time. I am told that my 'cache' is full and I need to re-start iTunes to clear some of the 'cache' memory. What is the cache and how do I resolve this?

CD download problems:
I used to be able to download numerous cd's at a time but now I can only do one or two until I restart iTunes. I have been told that my 'cache' is full and will only empty a little a each restart. I did look at the properties and the 'cache' is showing full How do I correct or improve
this?

Final Cut is a separate, higher end video editor. The pro version of iMovie.
Give iPhoto a look at for creating the slideshow. It's easy to assemble the photos in an album in iPhoto, put them in the order you want and then make a slideshow of them. You can select from various themes and transitions between slides and add music from your iTunes library.
When you have the slidshow as you want use the Export button at the bottom of the iPhoto window and export with Size = Medium or Large.
Save the resulting Quicktime movie file in your Movies folder.
Next, open iDVD, choose your theme and drag the QT movie file into the menu window being careful to avoid any drop zones.
Then follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
The reason I suggest iPhoto is that I find it much easier to use than iMovie (except for the older iMovie 6 HD version). Personal preferences showing here.

How do I delete caches in Lion and which can I delete?

How do I delete caches in Lion and which ones can be deleted?

you can delete all of them, they will be recreated as soon as the app opens again.
Clearing Local Caches
quit all open apps
open Finder press "shift+command+G" and type ~/Library/Caches
Drag all files and folders to the trash
Enter login password when prompted
Reboot
your system may seem slower after reboot, this is because the caches are being rebuilt.
Clearing Application Caches
quit all open apps
open Finder Press "shift+command+G" and type /Library/Caches
Drag all files and folders to the trash
Reboot

What is a cache monitoring? and what it is used for?

what is a cache monitoring? and what it is used for? how safe it is to execute the transaction RSRCACHE in development?
Thank you,

Hi Les,
Cache is a temporary storage for recently accessed data.
Used to enhance query performance.
Use t-code RSRT to view more on cache.
Please see this link:
http://help.sap.com/saphelp_nw04/helpdata/en/41/b987eb1443534ba78a793f4beed9d5/content.htm
Cache helps to improve query performance. As it can save data in memory, flatfile, cluster table or BLOB.
You can remove cache per query or inactivate it for perticular info provider or inactivate it overall.
But which is not recommended. Yes if u know that certain queries you dont use often and its not accessing large number of records then you can inactivate it for those queries. you can manage cache via three t-codes RSRT or RSRCACHE or SPRO>SAP Reference IMG>SAP Busines Wearhouse--> Reporting relevent setting -->General Reporting Setting in BEX -->Global Cache Setting.
please follow the link which has few good documents on cache. which will clear your complete concept for cache.
https://service.sap.com/bi -->Product information previous releases -->BI InfoIndex --> OLAP --> you will get bunch of documents in that.
Look at the following threads :
OLAP Cache
what is cache?
also check RSRT and OLAP cahce docs

Mapviewer cache server security

I have an Oracle Application Server with MapViewer deployed
There are some map tile layers prefetched so all the files are in <tile_storage default_root_path> directory.
Also there is an application that uses mapviewer
but if I write in the browser host:port/mapviewer/mcserver?request=gettile&format=PNG&zoomlevel=0&mapcache=name&mx=1&my=2, I get the image.
How can I restrict access to mapviewer cache server to nonauthenticated users, so the prefetched images could be accessed only through my application.
Thanks.

Hi!
First of all you can enable security constraints for +/mapviewer/*+ pages in you app server.

Disk cache javascript functions and images

Hi,
How can I force client browsers of my web application to cache the images and other javascript entities like css, functions, js files, etc.
By default it is not caching, though it should have. I have not written any code saying not to cache. Any help.
Environment : Tomcat server - java beans - jsp [struts framework]
In Netscape 7 if I say 'page view' it shows images and media files of my applications are not cached. Thats why application is really slow. If I compare this to some other web application which is fast, I see that media files, js files and images gets 'DISK CACHED'.]
Can anyone explain me what is disk cache and how to get it disk cached?
Thanks,
sunil

Thanks. I now understand whats the concept of disk cache.
But after lot of analysis also my problem still remains the same. Just that there are some patterns available.
I have some images in my own application. I also have some images which reference another site [application]. Interestingly all images which reside in my appication are not getting cached. All image which I refer into other site are getting cached. Can anyone makeout anything from this?
I looked into META tag generated for resulting htmls. But they dint have anything which says browser not to cache.
Can anyone list any java/jsp/html instructions which can tell browser not to cache stuff.
Or more importantly is there any setting or instruction or command which I can write in my java/jsp/html which can override any such setting done.
Thanks,
Sunil

In preferences what does "Override automatic cache management" mean and do?

I was wondering what "Override automatic cache management" means and does.

Firefox normally manages the size of it's cache, and can cache more or less information depending on various factors.
Checking this option allows you to specify the maximum size of the Firefox cache, in MB.
There isn't usually any need to enable this option.

Cant open pages that need log in info. I've cleared cache, disabled extensions and deleted all cookies to no avail....help!!!

Any page that requires a username and password will not open, this started last Thursday and at that time I was able to reinstate by clearing cache, disabling extension and deleting cookies. Subsequently that fix failed and now doing all those things has no effect.

I found the answer: http://forums.adobe.com/thread/1018071?tstart=0 It was a conflict with RealPlayer. Incidentally, in order to find this thread again, I had to use a google search. Is there really no way to find a person's own questions via our own profile???
