How to create a generalized version of the detailed polygons?

How to create a generalized version of the detailed polygons?
I have a table of detailed polygons (100+ vertices) and I want to get generalized version of these polygons.
For example, assume I have a polygon with 100 vertices. Distance between vertex n and n+1 is 1.0.
I want to get geometry (generalized polygon, line or point) where distance between vertex n and n+1 is 10.0 or more (I want vertices to be considered as one vertex if distance between them is less then 10.0).
Is it possible to create generalized version of polygons on the fly?
Any help is appreciated.
Thanks.

Scenario A:
If all of your polygons have no interaction among them (No polygon shares any boundary with any other ones).
In this case you can use the sdo_util.simplify in 10g to reduce the vertices in your polygons which returns new polygon geometries on the fly.
If you found that simplify is not doing exactly what you want, you can always roll out your own implementation using PL/SQL or the new SDOAPI JGeoemtry class in Java. Both will give you complete access to the coordinate arrays in a polygon and update them back to the database after you have simplified them in your code.
Scenario B:
If your polygons share boundaries, then the above methods will not work since the simplification process may not preserve the topology among your polygons. What you can do then is to use the Java topo package to create a new topology by adding all of your polygons to to an empty topology (which you first create in the database and then load into memory using oracle.spatial.topo.TopoMap). Once you have a topology built in the memory, you can use methods such as oracle.spatial.topo.TopoMap.changeEdgeCoords() to simplify the edges of your polygons. You can then recreate the simplified polygons from the topology. This is just a rough guide; for more details you need to check out the java doc for the various packages mentioned above which are shipped with 10g spatial.

Solaris 11 IPS: How do you post multiple versions of the same package?

How do you post multiple versions of the same software package on a single IPS instance(port)? Oracle was able to do it here with versions 151 and 175 of S11:
http://pkg.oracle.com/solaris/release/
Unfortunately, based on my searches, no where in the documentation (http://www.oracle.com/technetwork/server-storage/solaris11/technologies/ips-323421.html) does it explain to the development community how this is done. The best I can do is create pkg repo instances on different ports to host each different software version.
We are trying to deploy an IPS repository for our drivers and utilities that our customers can link to and pull updates from. We have been able to post a software package to the repository using the command:
pkgsend publish -s http://localhost:1234 -d ./ Appv1.p5m
This posts the package on the IPS repository instance at port 1234 on the server. However, we would like to post multiple versions of the package on the server at the same URL. Why the same URL? So that our customers and end-users need only point to a single URL to pull down our software rather than having to add a new URL to the publisher list each time we have an update. We want at least 5 of the previous software versions to be available on the server. Posting each version of the application or driver on a different IPS instance on a different port will require customers to add multiple URLs to their publisher list and they also will not be able to initiate remote scans for updates.
Has anybody been able to do this? Is any documentation forthcoming?

dhduvall: Thanks for your response. Yes, one would think that as long as the version numbers are different, you should be able to accumulate multiple versions of a package in a repository. It looks like Oracle has done it in their S11 repository unfortunately, as far as I know, they have not shared the steps on how to do this. I would like to publish two versions of the same package. I.E. two different manifests with two different fmri.pkg version strings and two different binaries.
If I publish one package after another like this:
pkgsend publish -s http://localhost:1234 Appv1.p5m
pkgsend publish -s http://localhost:1234 Appv2.p5m
Then only the second package shows up in the repository, as if it over-wrote the first one.
Running pkgsend with two manifest, like this:
pkgsend publish -s http://localhost:1234 Appv1.p5m Appv2.p5m
Will cause pkgsend to combine the packages and manifests as if they were a single package... not what I am trying to do.
Both approaches are complete without errors but neither achieves what I am trying to do.
alan.pae: Thank you. Unfortunately, the link didn't really help. I've read Oracle's white papers and IPS developer guide so I'm familiar with the topics covered.
Lex: Yes, I know. I specified the versions in the pkg.fmri value string.

How do I have multiple versions of the same .chm?

Our developers recently were required to make changes to an earlier version of our software (thank goodness for backups). So I'm having to revert to that earlier version, make changes, and create a revised .chm. HOWEVER, I already had completed the upcoming release's .chm and don't want to lose all of those changes. To make matters more complicated, I also have requests for changes to the Help for the future release.
So, how does everyone have multiple versions of the .chm on their system at the same time and keep them separate, yet compile the right files with the right version? I had thought I could just create a new folder with the files that changed for the various versions, but updating them in Word 2007 is not a pretty proposition. I'll then have to import them in and replace the "old" ones. There has to be an easier way! I'm sure other people do this on a regular basis, but this is the first time I've had to go back a version, maintain the next version, and start work on a yet-to-be-released version all at the same time.

It never ceases to amaze me how questions on the forum are like buses, none for an hour then three come along. Not your fault but this was asked just a couple of days ago.
When your developers issue a new version you need to save a copy of the source, we just zip it up. Then you carry on editing for the next version and zip that up and go again.
Then when a change is required to an older version, you dig it up, amend it and zip it again.
Not sure how it works with source control. The above is easier and reliable, assuming you manage it tightly.

How to create a temp table in the memory, not in disk?

in sql server, you can create a temp table in the memory instead of disk,
then you can do the insert, delete,update and select on it.
after finishing, just release it.
in Oracle,
I am wonderfing how to create a temp table in the memory, not in disk?
thanks,

Thanks for rectifying me Howard.
I just read your full article on this too and its very well explained here:
http://www.dizwell.com/prod/node/357
Few lines from your article
It is true, of course, that since Version 8.0 Oracle has provided the ability to create a Keep Pool in the Buffer Cache, which certainly sounds like it can do the job... especially since that word 'keep' is used again. But a keep pool is merely a segregated part of the buffer cache, into which you direct blocks from particular tables (by creating them, or altering them, with the BUFFER POOL KEEP clause). So you can tuck the blocks from such tables out of the way, into their own part of the buffer cache... but that is not the same thing as guaranteeing they'll stay there. If you over-populate the Keep Pool, then its LRU mechanism will kick in and age its contents out just as efficiently as an unsegregated buffer cache would.
Functionally, therefore, there can be no guarantees. The best you can do is create a sufficiently large Keep Pool, and then choose the tables that will use it with care such that they donâ€™t swamp themselves, and start causing each other to age out back to disk.
Thanks and Regards

How to create an alternative bom for the same product

Hi expert,
I want to know how to create an alternative bom for the same product. Can i use the different bom usage to create or use the same bom usage? In addition, how can i use the production version to link the alternative bom for the same product?
Please help me solve the problem.
Thanks in advance for any assistance.
George shi

HI
you can go with t-code CS01
if you have the BOM already and you want to create the alternative BOM then just goto create BOM
and enter the material and plant and uasge system will auto matically prapose the next numner ie, if you have Alt BOM1
then next system will prappose 2.
then you can enter the components as per you requirement
if you go to different BOM usage then sytem will not go for alternative BOM it gives again alt bom 1.
prodcution version you need to craet from mateial master
each version you can go woith alternative BOMS
Version 1 will have alt BOM1
Version 2 can haev ALT BOM2

How to create a record based on the name of a file in the file-system?

Hi,
With a lot of pictures I want to have a database to gather some information about these pictures.
First question is how to generate a record based on a file in the file system?
e.g. the pictures are "c:\fotos\2009\01\disc_001.jpg" to "c:\foto\2009\01\dis_98.jpg" .
now i want to create records with as one of the attributes the name of the picture (not the picture itself). how to create these records (based on the information of the file-ssytem). i.e. the number of records should be the same as the number of pictures.
any suggestions?
any reaction will be appreciated.

How to create multi garnishment order for the same garnishment document

Hi,
Can anyone tell me how to create multi garnishment order for the same garnishment document. I tried to copy the entry in IT0195 but the sequence field is grayed out so it will just delete the old record. What configuration should I do to make this possible?
Thanks a lot in advance.

hi,
As far as I got it.
You cannot have multiple Garnishment order but if a need arises you have to maintain it in IT216.
For that follow this path goto PA30->pernr->194->change->Garnishment->adjustment.
Since like order you cannot maintain adjustment also directly.

Can anybody help me how do I design such report....
Thanks

Hi Developer life,
According to your description that you want to dynamically increase and decrease the numbers of the columns in the table, right?
As Jason A Long mentioned that we can use the matrix to do this and put the year field in the column group, amount fields(Numric values) in the details, add an filter to filter the data base on this column group, but if
the data in the DB not suitable to add to the matrix directly, you can use the unpivot function to turn the column name of year to a single row and then you can add it in the column group.
If there are too many columns in the column group, it will fit the page size automatically and display the extra columns in the next page.

If your still have any problem, please try to provide us more details information, such as the data structure in the DB and the table structure you are currently designing.

I was refering to the "sample rate", normally 44.1 KHz, the iPod might not be able to play tracks with a non-standard rate. Otherwise I'm not sure what the issue might be.

Hello,
I think you can try two things : the soft reboot, and if it does not work, the hard reboot. Don't worry, you can't lose data with these two reboots.
Soft reboot :
1) Hit the three following keys at the same time :
- Alt
- Right Shift
- Delete
2) wait 2 minutes for the Blackberry to wake up.
Hard reboot :
1) your Blackberry device is on
2) remove the battery and wait for a minute
3) Put the battery back
4) wait 5 minutes for the device to wake up.
Please tell us if it works for you.
