Using a relational database
i want to develop a dictionary midlet. i have to use a database, since there will be about 70000 entries. is there any free or open-source database i can use with CLDC-MIDP-1.0?
how about if I use RMS? How will be the performance with so many entries; especially searching and sorting??
Performance would suck big time with RMS (RMS is one of the slowest things in MIDP). And I don't know how many entries you'll be able to put in there (unless you're target device is a high end phone with a lot of RMS memory). I think you should use a remote database and connect via the network to look up words...

Web Analysis Reports using a Relational Database
I would like to create a Web Analysis report using data from an Oracle database. From Web Analysis, I try to create a new database connection. I select Oracle as the Driver type. In the Database Connection String field, I replace {HOST-NAME} with the Host information from the TNSNAMES.ORA file. I've confirmed the Port number is correct. When I test the connection, it fails. What am I missing? The format of the Database Connection String that is defaulting into the field is:
jdbc:oracle:thin:@{HOST-NAME}:1521:ORCL
Is there anything else I need to include besides the Host name and Port number, for example, do I need to include the SID?
Thanks.
Terri T.The ojdbc14.jar currently exists in the following directories:
bea\weblogic81\server\lib
oracle\product\10.2.0\client_1
bea\weblogic81\server\ext\jdbc\oracle\920
There is a ojdbc14_g.jar that exists in:
bea\weblogic81\server\ext\jdbc\oracle\10g
bea\weblogic81\server\ext\jdbc\oracle\920
The classes12.jar file exists in:
oracle\product\10.2.0\client_1\oui\jlib
So from your response, I assume I need to copy classes12.jar to a directory under bea\weblogic81?
Thanks.

Need Recommendation of Online Sources in Learning to Use the Relational DBs
Please recommend some online sources in learning to use the relational databases; such as the ways relational databases are different from flat files, how to retrieve data from relational database tables. Thank you.
Actually I figured the OP was looking for a source that would instruct one in building ones own database rather than using an existing one.
Myself I would just buy a book (or read the one I already have.) I wouldn't expect to find to many sources like that online althoug one might find some college course materials for a class. -
Embedded LDAP Server or relational database
Hi,
I'm pretty new to this subject, but I do have a question. Here is the situation.
I need to set up a login portal (in weblogic 8.1) for a webapplication. Customers
(in the future) can login into a secure part of the website, where they can modify
their personal settings and information. We are talking about < 100.000 users.
Now I was thinking of using the embedded LDAP server to set up the authorisation
and identification, but because 2 variables are needed to see if it is a customer
of the company, I am also looking into the possibility of using a relation database
(oracle) to set up the username - password authentication table.
Can somebody tell me the (dis)advantages of using LDAP instead of the relational
database (oracle)? Or give me advise which authorisation method is the best one?
Your help is needed!
Thanks in advance,
Hans
the customer more information is needed toEnsure that the managed server is running with "Managed Server Independence Enabled" flag checked.
It can be checked on console via Environment --> Servers --> <ServerName> --> Configuration --> Tuning
For more information, please check
http://docs.oracle.com/cd/E14571_01/web.1111/e13708/failures.htm#START169
The above flag is required for the managed server to use the local LDAP repository.

Essbase as a source in OBIEE 11g and using lookup to Relation database
Hello All,
We are trying to implement Essbase as primary source for our obiee 11g repository and using relational database as secondary source of data.
I was using a lookup functionality in repository to lookup value from one of the Essbase's Dimension's attribute to relational database, however, there is error when testing this in OBIEE Dashboards.
And tried to look this error in support.oracle and googled it but was not able to find anything on it.
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 46008] Internal error: File server\Query\Src\SQLookupUtility.cpp, line 145. (HY000)
Have you had any such issue and how can we pass this issue?
I am trying to find if there are any quick resolution before going to oracle support.
TIA.
ParishIs Essbase 11.1.1.3 supported as a source for OBIEE 11g?From the certification matrix (http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/bi-11gr1certmatrix-166168.xls) we can see that only Essbase 9.3.3+ and 11.1.2+ are supported, not 11.1.1.3

Insert XML file into Relational database model without using XMLTYPE tables
Dear all,
How can I store a known complex XML file into an existing relational database WITHOUT using xmltypes in the database ?
I read the article on DBMS_XMLSTORE. DBMS_XMLSTORE indeed partially bridges the gap between XML and RDBMS to a certain extent, namely for simply structured XML (canonical structure) and simple tables.
However, when the XML structure will become arbitrary and rapidly evolving, surely there must be a way to map XML to a relational model more flexibly.
We work in a java/Oracle10 environment that receives very large XML documents from an independent data management source. These files comply with an XML schema. That is all we know. Still, all these data must be inserted/updated daily in an existing relational model. Quite an assignment isn't it ?
The database does and will not contain XMLTYPES, only plain RDBMS tables.
Are you aware of a framework/product or tool to do what DBMS_XMLSTORE does but with any format of XML file ? If not, I am doomed.
Constraints : Input via XML files defined by third party
Storage : relational database model with hundreds of tables and thousands of existing queries that can not be touched. The model must not be altered.
Target : get this XML into the database on a daily basis via an automated process.
Cheers.
Luc.Luc,
your Doomed !
If you would try something like DBMS_XMLSTORE, you probably would be into serious performance problems in your case, very fast, and it would be very difficult to manage.
If you would use a little bit of XMLType stuff, you would be able to shred the data into the relational model very fast and controlable. Take it from me, I am one of those old geezers like Mr. Tom Kyte way beyond 40 years (still joking). No seriously. I started out as a classical PL/SQL, Forms Guy that switched after two years to become a "DBA 1.0" and Mr Codd and Mr Date were for years my biggest hero's. I have the utmost respect for Mr. Tom Kyte for all his efforts for bringing the concepts manual into the development world. Just to name some off the names that influenced me. But you will have to work with UNSTRUCTURED data (as Mr Date would call it). 80% of the data out there exists off it. Stuff like XMLTABLE and XML VIEWs bridge the gap between that unstructured world and the relational world. It is very doable to drag and drop an XML file into the XMLDB database into a XMLtype table and or for instance via FTP. From that point on it is in the database. From there you could move into relational tables via XMLTABLE methods or XML Views.
You could see the described method as a filtering option so XML can be transformed into relational data. If you don't want any XML in your current database, then create an small Oracle database with XML DB installed (if doable 11.1.0.7 regarding the best performance --> all the new fast optimizer stuff etc). Use that database as a staging area that does all the XML shredding for you into relational components and ship the end result via database links and or materialized views or other probably known methodes into your relational database that isn't allowed to have XMLType.
This way you would keep your realtional Oracle database clean and have the Oracle XML DB staging database do all the filtering and shredding into relational components.
Throwing the XML DB option out off the window beforehand would be like replacing your Mercedes with a bicycle. With both you will be able to travel the distance from Paris to Rome, but it will take you a hell of lot longer.

The error below makes absolutely no sense! I'm using Enterprise Core...yet I'm being told I can't use remote data sources:
w3wp!library!8!03/05/2015-19:08:48:: i INFO: Catalog SQL Server Edition = EnterpriseCore
w3wp!library!8!03/05/2015-19:08:48:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: , Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: The feature: "The edition of Reporting
Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services.;
Really? This totally contradicts the documentation found here:
https://msdn.microsoft.com/en-us/library/ms157285(v=sql.110).aspx
That article says remote connections are completely supported.
ARGH! Why does this have to be so difficult to setup?!?Hi jeffoliver1000,
According to your description, you are using Enterprise Core edition and you are prompted that you can’t use remote data sources.
In your scenario, we neither ignore your point nor be doubt with what you say. But actually we have met the case before that even though the SQL Server engine is Enterprise but the reporting services is still standard. So I would recommend you to find the
actual edition of reporting services you are using. You can find Reporting Services starting SKU in the Reporting Service logs ( default location: C:\Program Files\Microsoft SQL Server\<instance name>\Reporting Services\LogFiles). For more information,
please refer to the similar thread below:

By the way, have you installed the other SQL Server edition before?

Web Analysis Report prompted for relational database login
We have given access to the WA reports and everything works fine in general. One of the user trying to open same report(s) document(s) via Workspace and its getting prompted with relational database login? I have verified for the access and everything seems to be fine.
I do not know the reason for this. Can anyone help me? Thanks.From the forums, i got the below MAXL commands to sync the user access :
alter system resync sss; --> this command will sync all the users, groups.
alter group <group name> sync security with all application; --> This can be used to individually sync the required group
alter user <user name> sync security with all application; --> This can be used to individually sync the required user
Will check it up with user on any change in her access.

How can I use an Express database build with RAA in Express Objects???
Hello, everybody!
I have installed Express Server and Client on my computer. I've build an Express database With Relational Access Manager mapping data from an Oracle database.
Now I want to use this express database in Oracle Express Objects.
I understand that an express database build with understand can be used by defining a connection to Express Server and using the option Relational Access Manager Connection.
But, I didn't understand the settings of this option. I open the settings window and there it is :
- the MASTER DATABASE Box where I have to write the name of the CUBE from the express database build with understand?
- the RDC File Box : what do I have to write here? I've read the HELP but I didn't understood. There is no file with the RDC extension in my computer.
Thank you for your help!
Anca.
[email protected]you can extend it, very easly, with an Airport Express.
once you connect the AExpress, on the App Airport Utility, in Wireless tab choose to "Extent a Network", you will be able to select your Network enter your Network Password and it is done
i have 2 AExpress to extend my signal and also to Airplay to Remote Speakers and works perfectly
good luck -
Not able to create XML from an existing relational database
Hi,
I am trying to create and xml from an existing relational database. I am not able to get any XML data, I receive "XMLTYPE()" as the result.
Here's the query -
SQL> select o.order_id, XMLELEMENT("order", XMLATTRIBUTES(o.order_id as ID)) AS "result" from order_
info o where order_id=2793;
ORDER_ID
result()
+2793+
XMLTYPE()
I was expecting to get +<order id=2793 />+ instead of XMLTYPE().
I am using -
SQLPlus: Release 9.0.1.0.1*
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
I have also run some checks to confirm XML DB installation -
SQL> select 1 from all_users where username = 'XDB';
+1+
+1+
SQL> desc RESOURCE_VIEW;
Name Null? Type
RES SYS.XMLTYPE
ANY_PATH VARCHAR2(4000)
RESID RAW(16)
I think, I have something wrong with installation or configuration.
Any idea about what have I done wrong here?Works fine now. Got the result "<order ID="2793"></order>".
Thanks. :-) -

What can be passing in this case... ?
Thanks in advanceThanks both
Really the problem initially was because of this:
[INS-06006] Passwordless SSH connectivity not set up between the following node(s): [node1, node2]. CVU may reports "PRVF-4007 : User equivalence check failed for user "user"" for same error
and I had to install node1 first and after node2 manually and perhaps for this the product was not well linked.
I resolved the problem establishing the keys with the wizard and after copying the following files from node1 to node2
/home/grid/.ssh -------> /home/grid/.ssh
authorized_keys
known_hosts
This is the procedure if you run the wizard at the node1.
The problem is that the wizard creates the keys incompletely...

How to store, in an effective way, analyzer data into a relational database?
We want to store the "sweep traces" of a network analyzer in a relational database in a way that it saves as much as possible space without loosing resolution.
The solutions were we thinking on are to separate the x-axes information from the y-axes information and store it in different tables of the database.
Because the repeating character of the measurements the data in the x-axes will be nearly all ways the same. So we want to store only new data in the x-axes table as a different x-axes is detected.
In a third table we want to save the relation between the x and y data and other data that belongs to the measurement.
Question is are there other or better possibilities to solve this proble
m?Hi Ben,
Thanks for you help.
The use of a third table that links the X-axe and y-axe table together depends on if I store the datapoints in the y-axe table sequential, so I need an identification of the points belonging together and I can have a varying number of data-points, (i.e. 401 of 801 ...) or I save it in one record.
The problem here is I have to save a varying nummer of points in tables with a lot of "datapoint columns".
Another solution is save the datapoints as a semicolon ( separated text string in one field.
Problem now is the limitation in the max. text field length.
In my Oracle Rdb database I can use "Varchar" fields.
(is here no limitation??)
In other databases a "Note field" will maybe give a solution.
The question sti
ll is: What is the best solution and uses the smallest amount of space?
In the next week I will do some tests with the solutions mentioned.
Please let me know what DSC is??
Greetings Huub -

CITADEL DATABASE NOT CONFIGURED AS A RELATIONAL DATABASE
HI:
I have the same problem described by another member before, and I haven't found any resolution of this problem:
The problem was:
>I enabled database logging, and configured the shared variables that I wanted to log. Then I deployed the variables. When I try to read alarms and events (Alarm & Event Query.vi), I get this message:
>Error -1967386611 occurred at HIST_RunAlarmQueryCORE.vi,
Citadel: (Hex 0x8ABC100D) The given Citadel database is not currently
configured to log alarms to a relational database.
Please help me with this topic
Thanks in advanceI'm configuring the variables to be logged in the same way that appears on the file you send, but it doesn't work... I don't know what else to do.
I'm sending you the configuration image file, the error message image and a simple vi that creates the database; after, values are logged; I generate several values for the variable, values that are above the HI limit of the acceptance value (previously configured) so alarms are generated. When I push the button STOP, the system stops logging values to the database and performs a query to the alarms database, and the corresponding error is generated... (file attached)
The result: With the aid of MAXThe data is logged correctly on the DATA database (I can view the trace), but the alarm generated is not logged on the alarms database created programatically...
The same vi is used but creating another database manually with the aid of MAX and configuring the library to log the alarms to that database.... same result
I try this sabe conditions on three different PCs with the same result, and I try to reinstall LabVIEW (development and DSC) completelly (uff!) and still doesn't work... ¿what else can I do?
I'd appreciate very much your help.
Ignacio
