Beginner question: There is no EPSG SRID for my data. What do I do?

Hi, I am pretty much an absolute beginner with Oracle and Oracle Spatial. I need to use a spatial reference system that is not included by default in 11g. I have read chapter 6 of the Spatial Developers Guide but am finding it difficult to determine the correct parameters to insert into SDO_COORD_REF_SYSTEM. Can anyone help??? This is the wkt from the .prj from my shapefile.
PROJCS("Albers Conical Equal
Area",
GEOGCS("GCS_North_American_1927",
DATUM("D_North_American_1927",
SPHEROID("Clarke_1866",6378206.4,294.9786982)),
PRIMEM("Greenwich",0.0),
UNIT("Degree",0.0174532925199433)),
PROJECTION("Albers"),
PARAMETER("False_Easting",0.0),
PARAMETER("False_Northing",0.0),
PARAMETER("Central_Meridian",-105.6855555555556),
PARAMETER("Standard_Parallel_1",40.38611111111113),
PARAMETER("Standard_Parallel_2",47.27722222222222),
PARAMETER("Latitude_Of_Origin",37.0),
UNIT("Meter",1.0))

These are the steps I used. Does this look right? It seems to have worked.

Is there any VIEW or FM for pulling data from VBAK, VBAP?also for VBEP,VBBE

Hi Experts,

Edited by: Srinivas on May 9, 2008 5:36 PM

Hi Srinivas,
You can use the view WB2_V_VBAK_VBAP2 for fetching data from VBAK and VBAP instead of using a JOIN. Note that, in the view, item data fields will have a I following the field name (POSNRI, MATNR_I are the item data fields from VBAP). The master data fields of VBAK are the same.
As far as i know, there are no standard views provided by SAP for VBEP and VBBE. Not sure if FM exists either.
While using FOR ALL ENTRIES clause make sure that you specify the entire primary key (EX. if selecting from VBAP specify VBELN and POSNR) as fields for selection or in the selection criteria. Its much better if you have the primary key in both. This is really important because without specifying the entire key and using FOR ALL ENTRIES will drastically bring down the performance. And also, If you are fetching not more than 100 or 200 entries using the clause it is fine, beyond that its same as using a select statement within LOOP...ENDLOOP.
So, you have to decide whether to use FOR ALL ENTRIES or a JOIN while selecting data depending on the requirement. If you don't have the entire key either in fields for selection or selection criteria, then its better to use a JOIN or VIEW.
The following is an example for using FOR ALL ENTRIES clause effectively.
         Select VBELN
                    POSNR
                    MATNR
            From VBAP
              into Table T_VBAP
          For All Entries in T_DATA
          Where VBELN eq T_DATA-VBELN
              And POSNR eq T_DATA-POSNR.
I hope this helps, Please let me know if you need further assistance.

Question about converting to Quicktime: "Searching for movie data"

Hi All -
I converted several clips on FCP to Quicktime files onto my MacBook Pro. They play just fine. However, when I send these files to someone else or try to play them when my external hard drive is disconnected from my MacBook, I get the following message: "Searching for movie data in file sequence Sequence1-FIN-0000006".
The sequence number changes from one movie to the next, of course. Either way, the QT file will not play unless my external hard drive is connected to my laptop.
Why is this? Am I converting wrong? I'm using the top Convert to Quicktime when exporting the footage.
Any insight would be very helpful.
Thanks!!

Don't mean to disagree David, but that's not it. What was exported were REFERENCE QT files...not SELF CONTAINED. Meaning that smaller files were made that reference the media on the Capture Scratch. They will work fine on your system, as the media being referenced is there. When someone else tries to open them, they get that error, because they don't have the media being referenced.
When you export QT Movies, you need to check the SELF CONTAINED box.

Is there settng source system level for master data delta loading perfo

Hi Viwers,
Good Morning,
I am loading data from the source to target level for Master data it is taking too much time,I would like to know the how to increase the master data delta loading performance.
I would like to know the source system level is there any setting requited & target system level also.
Please give your inputs..........
Thanks & Regards,
Venkat Vanarasi.

Venkat -
Are u deleting the indexes of data target before delta loading ? If not,delete the indexes of data target before delta loading and recreate them after delta loading is done.This procedure increase load performance.You can perform whole procedure in process chain.

2 system PLM setup question - Connecting to another ECC system for master data

I have been tasked with setting up the latest version of PLM in our environment. We have a free standing PLM Server (ECC 6.0 EHP7, SP2 with PLMWUI 747, SP3) that we would like to connect to another ECC system (ECC 6.0 EHP5, SP4 with PLMWUI 701, SP4) for its master data. In trolling around google and the marketplace, there isn't any setup guide or anything that really explains what the options are. Does anyone know what the possible setup options are or even better provide links to documents that show how to set this up? Can PLM be setup in the way that we want it to be?
Thanks in advance.

Hello Steve,
Unfortunately there isn't a lot of PLM documentation available.
I'm not sure I really understand what you need, but in essence, the PLM framework was developed using the SPI technology. That is, the Service Provider Infrastructure, which is a technology to split the UI from the business logic behind it. The idea is, in the end, you can have one single DB, connected to multiple systems and different types of UIs. (you can find some more details here: http://wiki.scn.sap.com/wiki/display/SPI/Home)
As far as I know, you have to do some customization in SPRO and maintain views /PLMB/V_RFC_DEST and /PLMB/V_RFC_LSYS. Everything else is done by the PLM framework via RFC connections.
Hope this helps you...

HT5312 I dont even remember when i answered the security questions but i put in all the right answers but it locked me out of my account. i see some people using "reset security questions" but that option isnt available for me. What do I do?

I cant buy anything on my phone or computer with my apple id.

The 'send reset info' only shows it you have a rescue email address (which is not the same thing as an alternate email address) set up on your account - if it's not showing then I assume that you don't have one, and you won't be able to add one until you can answer 2 of your questions. In which case see if the instructions on this user tip helps you get the questions reset : https://discussions.apple.com/docs/DOC-4551

A question on DataSource for Master Data example 0plant,0customer etc...,

I can get the field names of a standard data source for master data (say for example 0plant_attr) using table ROOSFIELD .
Now i want to know from which tables these fields are coming from.
How to get the table name for a each field in standard data source for master data .
For transaction data, transaction LBWE is there,similarly is there something like this for master data.
Another Question:
How to see communication structure for standard data source for master data ?

Hi,
the entire documentation for standard things in bi is avaialable in business content of net weavers in help.sap.com..... please refer this for any standard thing the entire documentation will be available.....

Is there an object like StringBuffer, but for binary data?

I like the performance of StringBuffer, it's very fast when I use the indexOf() and lastIndexOf() methods.
Is there an equivalent buffer object for binary data so that I can quickly search for byte sequences fast instead of looping through it?
Thanks.

I like the performance of StringBuffer, it's very fast when I use the indexOf() and lastIndexOf() methods.You mean fast as in O(n)?
Is there an equivalent buffer object for binary data so that I can quickly search for byte sequences fast instead of looping through it?A ByteBuffer might be useful, though you will have to loop - (thats what StringBuffer does)

Aggregates for master data & Line item Dimension

Hi i have question
1 Can we create Aggregate for Master Data?
2 Can we create Aggregate with Navigational Attributes?
3 Can we create Aggregate with Line Item Dimension?
4 How many dimension we can add with how many characteristics in it if we create a new Aggregate

1 Can we create Aggregate for Master Data? - No
2 Can we create Aggregate with Navigational Attributes? - No
3 Can we create Aggregate with Line Item Dimension? - No
4 How many dimension we can add with how many characteristics in it if we create a new Aggregate - You can create a maximum of 13 dimensions in the cube.You can add as many characteristics for an aggregate,adding many characteristics in the aggregate is as good as having the query fetch data from the Cube instead of the aggregates.
Aggregates are subsets infocubes derived from the main InfoCube to increase the query performance.You can create as many aggregates you want in an InfoCube.
For each aggregate,internally dimensions are created based on the selected characteristics.
Take a look at this link for detail information...

Is there an issue with incorrect tracking of data usage?

I just upgraded from a 4gig shared plan to 6. I never went over the previous plan, but now that I have more data, I've gone over. There is no difference in how we are using our phones, and when I look at the data usage for each phone on the plan (there are 4, all different phones) the times don't make sense - in some cases it appears that data is being used in the early morning hours when we are sleeping. In other cases, the are duplicate entries for the same dates and times. What the hell is going on? I don't even dare try to call Verizon customer service b/c I know I'll be on the phone with them for hours with no resolution or explanation that makes sens to me (it makes perfect sense to them, however). Anyone else experienced this?

Although I am not a conspiracy theorist I am reading more and more on the web that ever sense the Unlimited data went to shared or metered data, people that never exceeded data use previously are now seeing high overages. Of course Verizon will tell you nothing is wrong and it is all your problem. I can remember the old days when people were seeing phamton charges of data use at 99 cents and in the lawsuit that followed Verizon admitted it was an error. They made millions on that error but the class action settlement was peanuts. They still made millions even after admitting the practice.
I personally do not believe that the data counters are 100% accurate. Amazing that people on unlimited that used a few gigs of data if that n ow complain of excessive data over 3, 4, and 8 GB and up. Yeah the phones that were not using a whole lot of data before are suddenly data hogs. again I am sure there is a logical reason for the data jumps.
And no lets not just blame the users, or the device brand this situation is happening across all brand lines. Some more than others such as iPhone's but again this is all about the money.
And don't fall for the Verizon now has plans with double data for the same price, it is a ploy to garner more business. They see this as their answer to the Sprint & T-Mobile and now AT&T plans being offered.
You see with 99% cellular penetration Verizon and other providers have to do anything they can to get and keep customers.
It is big business. You must expect they have ways to generate as much money out of you they can.
Good Luck

Beginner question: Configure Tomcat for JAAS?

Hi,
This is a beginner question :-(. I'm trying to get JAAS to work on my Tomcat (6.0.12) installation. I used code from a Javaworld article (http://www.javaworld.com/javaworld/jw-09-2002/jw-0913-jaas.html)
Of course I had to configure my Tomcat to work together with JAAS. The document I used is: http://tomcat.apache.org/tomcat-6.0-doc/printer/realm-howto.html
According to the Tomcat doc I have to do the following steps before I can use JAAS to authenticate a user:
1. Develop your code. Place the compiled classes in Tomcat's classpath
2. Setup a login.config file for Java, and tell Tomcat where to find it (set JAVA_OPTS)
3. Configure the JAASRealm in your server.xml
1 Develop code: I use the following classes:
PassiveCallbackHandler.java
RdbmsCredential.java
RdbmsLoginModule.java
RdbmsPrincipal.java
These classes I put in the package rdbmsjaas.
In the %CATALINA_HOME%/webapps/Javaworld_Jaas/WEB-INF/lib directory I created the rdbmsjaas.jar file.
The jsp is called jaas.jsp, and is stored in %CATALINA_HOME%/webapps/Javaworld_Jaas
2. Setup login.config
In %CATALINA_HOME%\conf I saved the file Javaworld_all_that_Jaas.config, containing:
Example {
 RdbmsLoginModule required
 debug="true"
 url="jdbc:mysql://localhost/jaasdb?user=javauser&password=javadude"
 driver="com.mysql.jdbc.Driver";
};I created an XP Environment Variable JAVA_OPTS with the value <-DJAVA_OPTS=-Djava.security.auth.login.config==C:/Program Files/Apache Software Foundation/Tomcat 6.0/conf/JavaWorld_All_That_Jaas.config> (excluding < and >)
I used the fully qualified address, instead of $CATALINA_HOME/conf/JavaWorld_All_That_Jaas.config. I think XP balks when it sees $CATALINA_HOME).
3 Configure JAASRealm in server.xml
In %CATALINA_HOME%\conf\ I changed web.xml. I added the following lines:
 <Realm className="org.apache.catalina.realm.JAASRealm"
 appName="jaas"
 userClassName="rdbmsjaas.RdbmsPrincipal"
 debug="99"
 />If I run the jsp from http://localhost:8080/JavaWorld_Jaas/jaas.jsp, I can enter my username/password, but when I click the Submit button, I get:
Caught Exception: java.lang.SecurityException: Unable to locate a login configurationWhere did my configuration go wrong?

You will need a JSP/servlet engine such as Tomcat - Apache alone won't do it.
I haven't seen any tutorials on set-up but the Tomcat documentation includes info on how to link to Apache. There are also books you can buy - check out the online book stores such as Amazon.
There's also a lot of info on this forum.

You won't be able to change your rescue email address until you can answer your questions, you will need to contact Support in your country to get the questions reset.

Thanks. So there's no means of knowing whether a text message has been delivered, not to mention time of delivery. Perhaps I've gone for the wrong phone. It might do a lot but seems to miss out on some basics.

I forgot one of the answers to my security questions and my account was locked for 8 hours. Is there anyway around this? I am trying to change the questions.

I forgot one of the ansers to a security question and my account was locked for 8 hours. Is there anything I can do or do I have to wait 8 hours? I will probably get locked out again for providing the wrong answer. Can I change the security questions?
