Using oracle in combination with the mean-stack

Hi all,
I have been exploring the mean stack and saw the oracle-nodejs-passing by.
I am wondering what the best way is to replace/combine the mongodb with an oracle db (11g).
At this moment I have tried using mongoose for schema's and an json to XML parser to retrieve an xml-representation of the object I want to save.
To do some dml in the db I created some procedures which uses the xmltype in combination with xquery to update/insert.
Although it is working I am wondering this is the way to go. What are your experiences?
Regards,
Romano

The way to go is to use node-oracledb with Oracle 12.1.0.2 JSON datatype support: http://docs.oracle.com/database/121/ADXDB/json.htm
However, since you are still on 11g, using stored procedures to encapsulate logic seems like a good start.
You'll lose some performance using any ORM: do you really need one?

Using mod_alias in combination with dispatcher

Hi all,
In the example dispatcher configuration there is a setting called DispatcherDeclineRoot which has a comment saying: if turned to 1, request to / are not handled by the dispatcher, use the mod_alias then for the correct mapping. Can anyone explain how to use mod_alias in combination with the dispatcher module? For example, how can I configure it to serve static content for a specific alias and go to CQ for other requests? Can someone provide an example configuration?
Many thanks,
Jan

Hi,
It still doesn't quite work the way I want it to... Indeed, when you deny it in the dispatcher config, apache is trying to serve it. However, apache is looking for the file under /var/www/html which is the docroot configured in the dispatcher config. But my files are somewhere else, and there's an Alias defined for this in my apache config file. For some reason apache is not using this alias definition, the dispatcher docroot setting seems to be taking precedence. I tried several of the dispatcher settings (like DispatcherDeclineRoot and DispatcherUseProcessedURL) but to no avail. The reason why I'm not just putting my static files under /var/www/html is because I don't want them to get mixed up with the CQ cache. I want to be able to clear everything in the cache without touching these files I want to serve statically.
Any thoughts?

Jabn

Workaround for using Oracle JDBC extension with WLS pooling

Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.

Hello Eugene Voytitsky,
Thanks Eugene Voytitsky for your idea
I have tried the solution suggested by You, but it did not work.
It still throws ClassCastException.
I am sorry for posting the whole code of two classes below.
I did this to give you more clarity.
I am also indicating the place where the exception was thrown..
Please let me know if I am doing something wrong.

I'm having this same issue. I also have this line in my log, which is curious:

Is this related to the problem? What does it mean?

Can you use external hard drives with the HP Omni 10 5600US

Since this a Windows tablet, can you use external hard drives with the HP Omni 10 5600US?
I know there is a micro-sd reader for additional storage but can you use the usb for external hard drives like a regular pc?
I tried looking at the spec's for this tablet and it said the usb port was host only. I'm not sure what that means exactly.

Yes you can. You'll need to purchase a USB OTG (on-the-go) cable. I recommend using a drive that has its own power supply but I've successfully used small USB powered drives also.

Hi,
In such case I think is better to create a view an perform the delete using it. Example (using HR schema):

How can I use oracle function to decode the encode value

Hi everybody,
If the data is encode value how can I decode this value

DBMS_OBFUSCATION_TOOLKIT
DBMS_OBFUSCATION_TOOLKIT allows an application to encrypt data using either the Data Encryption Standard (DES) or the Triple DES algorithms.
The Data Encryption Standard (DES), also known as the Data Encryption Algorithm (DEA) by the American National Standards Institute (ANSI) and DEA-1 by the International Standards Organization (ISO), has been a worldwide encryption standard for over 20 years. The banking industry has also adopted DES-based standards for transactions between private financial institutions, and between financial institutions and private individuals. DES will eventually be replaced by a new Advanced Encryption Standard (AES).
DES is a symmetric key cipher; that is, the same key is used to encrypt data as well as decrypt data. DES encrypts data in 64-bit blocks using a 56-bit key. The DES algorithm ignores 8 bits of the 64-bit key that is supplied; however, developers must supply a 64-bit key to the algorithm.
Triple DES (3DES) is a far stronger cipher than DES; the resulting ciphertext (encrypted data) is much harder to break using an exhaustive search: 2**112 or 2**168 attempts instead of 2**56 attempts. Triple DES is also not as vulnerable to certain types of cryptanalysis as is DES. DES procedures are as follows:
DESEncrypt Procedure
DESDecrypt Procedure
Oracle installs this package in the SYS schema. You can then grant package access to existing users and roles as needed. The package also grants access to the PUBLIC role so no explicit grant needs to be done.
This chapter discusses the following topics:
Overview of Key Management
Summary of DBMS_OBFUSCATION Subprograms
Overview of Key Management
Key management, including both generation and secure storage of cryptographic keys, is one of the most important aspects of encryption. If keys are poorly chosen or stored improperly, then it is far easier for a malefactor to break the encryption. Rather than using an exhaustive key search attack (that is, cycling through all the possible keys in hopes of finding the correct decryption key), cryptanalysts typically seek weaknesses in the choice of keys, or the way in which keys are stored.
Key generation is an important aspect of encryption. Typically, keys are generated automatically through a random-number generator. Provided that the random number generation is cryptographically secure, this can be an acceptable form of key generation. However, if random numbers are not cryptographically secure, but have elements of predictability, the security of the encryption may be easily compromised.
The DBMS_OBFUSCATION_TOOLKIT package does not generate encryption keys nor does it maintain them. Care must be taken by the application developer to ensure the secure generation and storage of encryption keys used with this package. Furthermore, the encryption and decryption done by the DBMS_OBFUSCATION_TOOLKIT takes place on the server, not the client. If the key is passed over the connection between the client and the server, the connection must be protected using Oracle Advanced Security; otherwise the key is vulnerable to capture over the wire.
Key storage is one of the most important, yet difficult aspects of encryption and one of the hardest to manage properly. To recover data encrypted with a symmetric key, the key must be accessible to the application or user seeking to decrypt data. The key needs to be easy enough to retrieve that users can access encrypted data when they need to without significant performance degradation. The key also needs to be secure enough that it is not easily recoverable by an unauthorized user trying to access encrypted data he is not supposed to see.
The three options available to a developer are:
Store the key in the database
Store the key in the operating system
Have the user manage the key
Storing the Key in the Database
Storing the keys in the database cannot always provide bullet-proof security if you are trying to protect data against the DBA accessing encrypted data (since an all-privileged DBA can access tables containing encryption keys), but it can provide security against the casual snooper, or against someone compromising the database files on the operating system. Furthermore, the security you can obtain by storing keys in the database does not have to be bullet-proof in order to be extremely useful.
For example, suppose you want to encrypt an employee's social security number, one of the columns in table EMP. You could encrypt each employee's SSN using a key which is stored in a separate column in EMP. However, anyone with SELECT access on the EMP table could retrieve the encryption key and decrypt the matching social security number. Alternatively, you could store the encryption keys in another table, and use a package to retrieve the correct key for the encrypted data item, based on a primary key-foreign key relationship between the tables.
A developer could envelope both the DBMS_OBFUSCATION_TOOLKIT package and the procedure to retrieve the encryption keys supplied to the package. Furthermore, the encryption key itself could be transformed in some way (for example, XORed with the foreign key to the EMP table) so that the key itself is not stored in easily recoverable form.
Oracle recommends using the wrap utility of PL/SQL to obfuscate the code within a PL/SQL package itself that does the encryption. That prevents people from breaking the encryption by looking at the PL/SQL code that handles keys, calls encrypting routines, and so on. In other words, use the wrap utility to obfuscate the PL/SQL packages themselves. This scheme is secure enough to prevent users with SELECT access to EMP from reading unencrypted sensitive data, and a DBA from easily retrieving encryption keys and using them to decrypt data in the EMP table. It can be made more secure by changing encryption keys regularly, or having a better key storage algorithm (so the keys themselves are encrypted, for example).
Storing the Key in the Operating System
Storing keys in the operating system (that is, in a flat file) is another option. With Oracle8i you can make callouts from PL/SQL, which you could use to retrieve encryption keys. If you store keys in the O/S and make callouts to retrieve the keys, the security of your encrypted data is only as secure as the protection of the key file on the O/S. Of course, a user retrieving keys from the operating system would have to be able to either access the Oracle database files (to decrypt encrypted data), or be able to gain access to the table in which the encrypted data is stored as a legitimate user.
User-Supplied Keys
If you ask a user to supply the key, it is crucial that you use network encryption, such as that provided by Oracle Advanced Security, so the key is not passed from client to server in the clear. The user must remember the key, or your data is nonrecoverable.

Can I use Oracle app server with mysql

Can I use Oracle app server with mysql. I seem to have the following error when trying to create a datastore. I have mysql.jar in my classpath. Can any one tell me what's wrong.
Error initializing data-source 'jdbc/topup': DriverManagerDataSource driver 'org.gjt.mm.mysql.Driver' not found

Yes you can forward requests from your own apache to the iAS. This can be done using mod_proxy. Some hints about how to do this are availlable on this forum.
mod_oc4j is not a standard apache module, and therefore is not availlable when you download apache. There is no apparent reason to use mod_oc4j on a "regular" webserver (unless you want to build your own iAS). Also there might be some licenseing issues with using mod_oc4j module on a standard apache.
You can encrypt data that is passed from a random Apache to you iAS.

Advantages and Disadvantages of Using Oracle 7 Client with Oracle 9 Server

Hello,
I was wondering what are the advanatges of using Oracle 7 client with Oracle 9 Server versus using Oracle 9 Client with Oracle 9 server.

Some years ago I used 7.3 Client with 9i DB, and I don't remember of particular problems, but I'm speaking of Sql*Plus only. Are there specific problems ?
Of course the best thing is to install one 9i Client (did you already do it ?) : if there are same problems, then that's not compatibility issue.
And what are advantages of using 9 Client with 9 server other than 7 is no longer supported.You're sure you won't have compatibility problems.

Hi Boris,
Looks like you have not run the post upgrade script for 10.1.3.4.
You need to install SOA 10.1.3.4 Basic Installation. Then start following : http://download.oracle.com/docs/cd/E12524_01/core.1013/e13058/weblogic.htm#BHCIIBFB
You basically, first install 10.1.3.4 basic SOA install, Apply the Opatch 7337034 (HOTPLUG: SOASUITE 10.1.3.4 ON WEBLOGIC 9.2 - CHANGES FOR HOTPLUGGABILITY). Install WLS 9.2 MP3.
Now, Download the Oracle SOA Suite 10.1.3.4 WebLogic Server 9.2 : patch : 7490612.
Then , Modify the following mandatory installation properties in the Weblogic_SOA10134_Base\SOADomain.properties file as per the documentation above.
Cheers

Can't use certain filters- "problem with the filter module interface"

Hello,
I frequently use the BPelt Flatten and Multifill plugins and they have always worked perfectly until today. Now I get the following error: "Could not complete the [Multifill/Flatten] command because of a problem with the filter module interface."
I use Photoshop CS6 Extended with the Creative Cloud membership, and just recently updated to version 13.1.1 x64. I believe this may be related, as the plugins worked before the update and nothing else has changed. Any recommendations on how to fix this? Is it possible to undo the update?

Usually this means a bug in the third party plugin that you are using.

Is it possible to use Oracle Forms 10g with Oracle 10g Lite Database?

Hi All,
We are in process of migrating our forms from 6i to 10g environment.
We have two kinds of applications, one set run on general Oracle 11g database and the other set of forms run at the client machine using Oracle lite database.
We dont have any problem with Forms 6i to connect to Lite database as it allows to connect through ODBC:DSN names. When we try to connect to a lite database (10gR3) from Forms 10g through ODBC/DSN, it's not allowing and throwing the below error.
ORA-03121 : no interface driver connected - function not performed
Can someone tell me if there is something wrong in our approach? Also advise how to use Oracle Lite database with Forms 10G.
Sincerely,
Praveen Manthena

Hi,
I have experience with 6i with lite database 10g. There are two version of lite database one is multi language support and other one in english. There lang problem in connectivity with multi language 10g lite database. I done connectivity with single language connectivity of 6i with 10g lite database. You should try this one with forms 10g.

how can i use my apple ID with the itune store over my windows laptop

If you don't have iTunes installed on your laptop then you can download and install it from here : http://www.apple.com/itunes/download/
You can then log into your account on it via the Store > Sign In menu option (on iTunes 11 on a PC you can get the menus to show via control-B) :
And you can then select the Store on the left-hand sidebar (you can enable the sidebar via control-S), and then browse items in the store and buy them by clickin on their price.

How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

The Guest Network function of the Time Capsule and AirPort Extreme cannot be enabled when the device is in Bridge Mode. Unfortunately, with another router...the Telus...upstream on your network, Bridge Mode is indicated as the correct setting for all other routers on the network.
If you can replace the Telus gateway with a simple modem (that performs no routing functions), you should be able to configure either the Time Capsule or the AirPort Extreme....whichever is connected to the modem....to provide a Guest Network.
