setting up oracle native encryption in web.config file - c#

We need to setup following properties in config file to enable native encryption of oracle
SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT = (MD5)
SQLNET.ENCRYPTION_TYPES_CLIENT = (AES256)
SQLNET.ENCRYPTION_CLIENT = required
SQLNET.CRYPTO_CHECKSUM_CLIENT = required
Below is the link where I found out it can be done through config file (search for the above properties in link page e.g. ENCRYPTION_CLIENT)
https://docs.oracle.com/cd/E63277_01/win.121/e63268/InstallManagedConfig.htm#ODPNT8164
I was not able to find any good example till now.
Can anyone provide an example or link to see how to enable encryption from config file.

In Configuration section add the below lines.
<configSections>
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.19.1, Culture=neutral, PublicKeyToken=89b483f429c47342" />
</configSections>
Connection String:
<add key="ConnectionString" value="Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=server name)(PORT=XXXX))(CONNECT_DATA=(SERVICE_NAME=service name)));" />
Add the below section under runtime section:
<oracle.manageddataaccess.client>
<version number="*">
<settings>
<setting name="sqlnet.encryption_types_client" value="aes256" />
<setting name="sqlnet.encryption_client" value="required" />
</settings>
</version>
</oracle.manageddataaccess.client>

How to retrieve the value for the Key in the Web.Config using DictionarySectionHandler

How to fetch the corresponding value of a key that I would get dynamically. I wish to use the system defined DictionarySectionHandler to do the job, of fetching the data from my custom built config section in the Web.config file
Code block in Web.Config
<section name="domainsource" type="System.Configuration.DictionarySectionHandler"/>
<domainSource>
<add key="0" value="170" />
<add key="1" value="171" />
<add key="2" value="172" />
<add key="3" value="173" />
<add key="12" value="174" />
</domainSource>
Sourcecode in the main cs file from where I wish to retrieve the data from the Web.Config
Hashtable statusCodes = ConfigurationManager.GetSection("domainSource") as Hashtable;
vDomainSource = statusCodes[vDomainID];
This is where I am stuck vDomainID would be a value 0/1/2/3/12, based on this value I need to fetch its respective Source from the Web.Config. Any help on this aspect would be really appreciated.
You have a missspelling in the defintion of the section domainsource -> domainSource. Further ensure that the elemnt is defined in an element. Then it should work.
<configuration>
<configSections>
<section name="domainSource" type="System.Configuration.DictionarySectionHandler"/>
</configSections>
<domainSource>
<add key="0" value="170" />
<add key="1" value="171" />
<add key="2" value="172" />
<add key="3" value="173" />
<add key="12" value="174" />
</domainSource>
</configuration>

Paypal: Configuration.GetApiContext -> VS: Cannot resolve Issue

If I install .Net SDK and uses Sample Code, VS says: Cannot resolve symbol 'Configuration' at this line:
var apiContext = Configuration.GetAPIContext();
So, what DLL or namespaces did I missed?
It is a wrapper class around the configuration section.
Please look into \PayPal-NET-SDK-develop\Samples\Source\Utilities\Configuration.cs and create it to suit your configuration.
Don't forget to modify your web.config or app.config
<configSections>
<section name="paypal" type="PayPal.SDKConfigHandler, PayPal" />
</configSections>
<!-- PayPal SDK settings -->
<paypal>
<settings>
<add name="mode" value="sandbox" />
<add name="clientId" value="youclientid" />
<add name="clientSecret" value="yoursecret" />
</settings>

Procedure with out parameter (SYS_REFCURSOR) with Entity Framework

I'm performing a migration of database, SQL Server to Oracle, in a C# application. The application mentioned, is using Entity Framework to access the database.
In this database there's a procedure that returns a "ComplexType", I researched and found that Oracle does not understand the "ComplexType" and I need to perform the mapping of the output parameter in web.config, then:
<oracle.manageddataaccess.client>
<version number="*">
<implicitRefCursor>
<storedProcedure schema="ALERTA_MPLUS" name="PR_CONSULTA_DADOS_ROBO">
<refCursor name="CV_1">
<bindInfo mode="Output" />
<metadata columnOrdinal="0" columnName="Broker" baseColumnName="Broker" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="50" />
<metadata columnOrdinal="1" columnName="Companhia" baseColumnName="Companhia" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="100" />
<metadata columnOrdinal="2" columnName="Metrica" baseColumnName="Metrica" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="50" />
<metadata columnOrdinal="3" columnName="Q1" baseColumnName="Q1" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="4" columnName="Q2" baseColumnName="Q2" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="5" columnName="Q3" baseColumnName="Q3" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="6" columnName="Q4" baseColumnName="Q4" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
</refCursor>
</storedProcedure>
</implicitRefCursor>
</version>
</oracle.manageddataaccess.client>
This mapping worked perfectly in the development environment, but when I passed the application for approval gave the following error:
I've tried some solutions but none was successful:
ODAC installed on the server approval;
Searching, I found the Oracle documentation that indicates the mapping that way:
<oracle.dataaccess.client>
<settings>
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursor.CV_1" value="implicitRefCursor bindinfo='mode=Output'" />
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursorMetaData.CV_1.Column.0" value="implicitRefCursor metadata='ColumnName=Broker;BaseColumnName=Broker;BaseSchemaName=ALERTA_MPLUS;BaseTableName=tt_Resultado_Final;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursorMetaData.CV_1.Column.1" value="implicitRefCursor metadata='ColumnName=Companhia;BaseColumnName=Companhia;BaseSchemaName=ALERTA_MPLUS;BaseTableName=tt_Resultado_Final;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursorMetaData.CV_1.Column.2" value="implicitRefCursor metadata='ColumnName=Metrica;BaseColumnName=Metrica;BaseSchemaName=ALERTA_MPLUS;BaseTableName=tt_Resultado_Final;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />

<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursorMetaData.CV_1.Column.5" value="implicitRefCursor metadata='ColumnName=Q3;BaseColumnName=Q3;BaseSchemaName=ALERTA_MPLUS;BaseTableName=tt_Resultado_Final;NATIVEDATATYPE=NVarchar2;ProviderType=NVarchar2'" />
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursorMetaData.CV_1.Column.6" value="implicitRefCursor metadata='ColumnName=Q4;BaseColumnName=Q4;BaseSchemaName=ALERTA_MPLUS;BaseTableName=tt_Resultado_Final;NATIVEDATATYPE=NVarchar2;ProviderType=NVarchar2'" />
</settings>
</oracle.dataaccess.client>
This is code return the following error (in all environments):
ORA-06550: line 1, colunm 8: PLS-00306:
wrong number or types of arguments in call to
'PR_CONSULTA_DADOS_ROBO' ORA-06550: line 1, colunm 8: PL/SQL:
Statement ignored;
I published the application on another machine (another developer) and also worked;
Some information that I think are necessary:
Visual Studio 2013;
Oracle.DataAcess.dll version 4.121.1.0;
Oracle.ManagedDataAccess.dll version 4.121.1.0;
ISS 7.0;
Pool - Enable 32-bit Applications true;
If you can help me...
Very thanks in advance!
After many trials and errors managed to solve. I do not know if it is the best solution but worked.
In machine.config exists a definition of <oracle.manageddataaccess.client>:
<configSections>
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
</configSections>
So I added this declaration in web.config and it worked perfectly.
I had the same issue and this showed me the way to a solution.
The cause of the issue was that I had installed the OracleManagedDataAccessClient through NUGET but someone else had done a native install of the client. When the client was installed, it created an entry in the Machine.Config. When NUGET installed it created an entry in the Web.config. When trying to execute, I received an error that the section for:
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
Already existed. I commented it out and my service worked but Oracle would fail with the error:
"PLS-00306: wrong number or types of arguments in call"
When the client was installed it was an earlier version of Oracle so the entry in the Machine.config was:
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.**1**.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
Since I commented the entry in web.config, the application used the machine.config entry which did not match the actual version.
I modified the entry in the machine.config to match the web.config and everything now works.

can not find schema info when configuration quartz.net

When i add this code to app.config in Windows service program:
<quartz>
<add key="quartz.scheduler.instanceName" value="ExampleDefaultQuartzScheduler"/>
<add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz"/>
<add key="quartz.threadPool.threadCount" value="10"/>
<add key="quartz.threadPool.threadPriority" value="2"/>
<add key="quartz.jobStore.misfireThreshold" value="60000"/>
<add key="quartz.jobStore.type" value="Quartz.Simpl.RAMJobStore, Quartz"/>
</quartz>
it tips:
Could not find schema information for the element `key`.
Could not find schema information for the attribute `quartz`.
Could not find schema information for the element `value`.
I am sure i have using job_scheduling_data_2_0.xsd file in background.
And predefine the quartz:
<configSections>
<section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
Where is the problem?And where to find the schema info?
And when is the label <quartz> namespace?
Where should i find the xsd file of quartz.net?
Normal reason is your config file lack of schema file like *.xsd in:..\Microsoft Visual Studio\Xml\Schemas folder.
You can omit these tips,it could not affect your program running.
Or you can write the xsd schema file by yourself.

How to use ConfigurationManager.AppSettings with a custom section?

I need to get "http://example.com" from using App.config file.
But at the moment I am using:
string peopleXMLPath = ConfigurationManager.AppSettings["server"];
I cannot get the value.
Could you point out what I am doing wrong?
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<configSections>
<section name="device" type="System.Configuration.SingleTagSectionHandler" />
<section name="server" type="System.Configuration.SingleTagSectionHandler" />
</configSections>
<device id="1" description="petras room" location="" mall="" />
<server url="http://example.com" />
</configuration>
I think you need to get the config section, and access that:
var section = ConfigurationManager.GetSection("server") as NameValueCollection;
var value = section["url"];
And you also need to update your config file:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<configSections>
<section name="device" type="System.Configuration.NameValueSectionHandler" />
<section name="server" type="System.Configuration.NameValueSectionHandler" />
</configSections>
<device>
<add key="id" value="1" />
<add key="description" value="petras room" />
<add key="location" value="" />
<add key="mall" value="" />
</device>
<server>
<add key="url" value="http://example.com" />
</server>
</configuration>
Edit: As CodeCaster mentioned in his answer, SingleTagSectionHandler is for internal use only. I think NameValueSectionHandler is the preferred way to define config sections.
The SingleTagSectionHandler documentation says:
This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
You can retrieve it as a HashTable and access its entries using Configuration.GetSection():
Hashtable serverTag = (Hashtable)ConfigurationManager.GetSection("server");
string serverUrl = (string)serverTag["url"];
string peopleXMLPath = ConfigurationManager.AppSettings["server"];
gets the value from the appSettings part of the app.config file but you are storing your value in
<server url="http://example.com" />
Either put the value in the appSettings section as below or retrieve the value from its current location.
You need to add a key value pair to your config's appSettings section. As below:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="server" value="http://example.com" />
</appSettings>
</configuration>
Your reading code is correct but you should probably check for null. If the code fails to read the config value the string variable will be null.
You're defining a configuration section instead of a value in AppSettings. You can simply add your setting to AppSettings:
<appSettings>
... may be some settings here already
<add key="server" value="http://example.com" />
</appSettings>
Custom config sections are typically used for more complicated configurations (e.g. multiple values per key, non-string values, etc.
If you want to get the value from the app settings your appsetting element in configuration file must have a key.
define your sever value as mentioned below under configuration section:
<configuration>
<appSettings>
<add key="server" value="http://example.com" />
</appSettings>
...
...
...
</configuration>
Now execute below code line to get the server url:
string peopleXMLPath = ConfigurationManager.AppSettings["server"].ToString();
