https://dbagenesis.com/p/oracle-11g-advanced-dba DBA Genesis provides all you need to build and manage effective Oracle technology learning. We designed DBA Genesis as a simple to use yet powerful online Oracle learning system for students. Each of our courses is taught by an expert instructor, and every course is available on demand. A listener is a separate process than your database processes which runs on the database server to accept incoming connections. Any client connection first lands on to database listener and then its handed over to the PMON process. All the databases running on a server must have their services registered with the listener or else listener will not be able to accept the incoming connections.

A listener is configured with one or more listening protocol addresses, information about supported services, and parameters that control its run-time behavior. The listener configuration is stored in a configuration file named listener.ora. Because all of the configuration parameters have default values, it is possible to start and use a listener with no configuration. This default listener has a name of LISTENER, supports no services on startup, and listens on the following TCP/IP protocol address: (ADDRESS=(PROTOCOL=tcp)(HOST=host_name)(PORT=1521)) The listener forwards client requests to supported services. These services can be configured statically in the listener.ora file or they can be dynamically registered with the listener. This dynamic registration feature is called service registration. The registration is performed by the PMON process, an instance background process of each database instance that is configured in the database initialization parameter file. Dynamic service registration does not require any manual configuration in the listener.ora file. Service registration offers the following benefits: Simplified configuration Service registration reduces the need for the SID_LIST_listener_name parameter setting, which specifies information about the databases served by the listener, in the listener.ora file.

Configuring the listener The listener is the utility that runs constantly in the background on the database server, listening for client connection requests to the database and handling them. It can be installed either before or after the creation of a database, but there is one option during the database creation that requires the listener to be configured

In 2012, details of a vulnerability in the Oracle Database listener were published that allows an attacker to register with the database listener and to intercept and modify TNS network traffic between the client and database server. This “TNS Poison” attack allows an unauthenticated attacker with only network connectivity to compromise most database accounts. The fix to prevent TNS Poison attacks was announced in April 2012, but was not fixed by the Critical Patch Update securtiy patch. Instead, manual changes are required to the database listener prior to 12c. Even though this vulnerability is four years-old, Integrigy routinely identifies vulnerable Oracle databases during our security assessments – hence the purpose of this webinar. This education webinar demonstrates a TNS poison attack and how an Oracle database can be compromised without any database authentication. Required remediation steps for each database version are discussed as well as methods for checking if a database is protected or if it has been compromised.

Hi everyone, Andy from Easysoft Limited here, what I want to show you today is how to get data from SQL Server into Oracle. Now for this we will be accessing SQL Server 2014 from Oracle 12 and getting data across. This could be quite easily be any SQL Server version from 2008 and any Oracle version from 11.2, the configuration and process is the same. We can obviously get access to data on SQL Server prior to 2008 and Oracle prior to version 11.2 but it will need a different configuration to what I am going to show you today The plan is also to add more data to the SQL Server table and show this new data back in Oracle. To start off you'll need access to ensure that you have access to your SQL Server and Oracle databases. You'll also need the Easysoft SQL Server ODBC Driver available from www.easysoft.com; just download it, install it and request the free 14 day trial licence. Before we start we need to make some changes to the standard Easysoft config files. cat /etc/odbc.ini Here I have changed Mars Connection to Yes. It must be set to "Yes" if you are connecting to SQL Server 2005 or newer. Easysoft supports all SQL data types from the version of SQL Server from version 7. Oracle supports data types that are common to most ODBC Drivers, but not some of the SQL Server ones. If you intend to access VARCHAR(MAX) for example, then there are some additional settings that need to be set up. Now as I would like to show you VARCHAR(MAX) data moving from SQL Server to Oracle, I have made the relevant change. As you can see, VarMaxAsLong says "Yes" We now need to create a link from Oracles Database Gateway (DG4ODBC) to the ODBC datasource that we already have, this is done in an init(sid) oracle file; let's have a look at our file. cat $ORACLE_HOME/hs/admin/initsqlsrv.ora Please note that HS_NLS_NCHAR must be set to UCS2 Oracle assume that most database vendors use UTF-8 for wide characters, however Easysoft, like almost all ODBC Driver vendors (including Oracles own ODBC Driver) uses UCS2 for wide characters. So that's the link between DG4ODBC and the datasource setup correctly. Next we need to set up the Listener entry The Oracle Listener waits for incoming requests from the Oracle database. For the Oracle Listener to listen for requests, information about DG4ODBC must be added to the Oracle Listener configuration file, listener.ora cat $ORACLE_HOME/network/admin/listener.ora The PROGRAM=dg4odbc tells the Listener that we are wanting to use the Oracle database gateway to communicate with ODBC. The ENVS=LD_LIBRARY_PATH tells Oracle what library to load Now that's all set up and OK we need to tell Oracle which server to attach the listener entry to. This is done in tnsnames.ora, and he is the file that we ensured was set up earlier. cat $ORACLE_HOME/network/admin/tnsnames.ora The Oracle Listener now needs to be restarted. lsnrctl stop lsnrctl start OK, that's now started the Listener up again. So we have ensured that all the configuration files are set up correctly. The Listener and tnsnames.ora both set up OK. The final step is to create a link from the Oracle database to the "tnsnames.ora" entry. CREATE PUBLIC DATABASE LINK ODBC CONNECT TO "test" IDENTIFIED BY "test" USING 'sqlsrv_ptr'; Right, that's all done. Let's access the data in SQL Server now. select * from [email protected]; Where 'demo' is the name of the SQL Server table and 'odbc' is the public database link name. OK, there we have the data. So to recap, I'm in Oracle and we have managed to read the data from SQL Server. Let's just add an additional row in that SQL Server table and retrieve the new data in Oracle. quit; /usr/local/easysoft/unixODBC/bin/isql.sh -v sqlsrv insert into demo values (2,'Easysoft') select * from demo select * from [email protected]; And there is the new data. Easysoft Limited can help you with your data access ... for our full range of ODBC and JDBC Drivers, Bridges and Gateways visit easysoft.com Be sure to let us know if you have any comments or questions. Until next time, thanks again and we'll see you again soon.

Oracle clients communicate with oracle databases using Oracle Net Services over TCP/IP. On database server, oracle Net Services has a component called LISTENER that listens connection request on a port. A Listener has a configuration file called listener.ora in $ORACLE_HOME/network/admin folder. Sample listener.ora file:

Step 1: Go to dbhome --- hostname_SID --- Sysman --- Config --- open emd.properties in notepad and set the value agentTZRegion=+06:00 to the value of your timezone and click save. You can also do it using export and time zone reset commands. Step 2: ALTER DATABASE SET TIME_ZONE='+06:00'; according to your time zone. You can check DB TIME Zone using " select dbtimezone from dual ; ". Step 3: In step 2 if you get the error "ORA-30079: cannot alter database timezone when database has TIMESTAMP WITH LOCAL TIME ZONE columns" then please FOLLOW following steps SQL--- select count (*) from dba_tab_columns 2 where data_type like 'TIMESTAMP%WITH LOCAL TIME ZONE' ; COUNT(*) 1 In this case there is only one table. The owner and name can be determined by: SQL--- select owner, table_name from dba_tab_columns 2 where data_type like 'TIMESTAMP%WITH LOCAL TIME ZONE'; OWNER TABLE_NAME ------------------------------ OE ORDERS SQL--- desc oe.orders ; Name Null? Type -------- ORDER_ID NOT NULL NUMBER(12) ORDER_DATE NOT NULL TIMESTAMP(6) WITH LOCAL TIME ZONE ORDER_MODE VARCHAR2(Cool CUSTOMER_ID NOT NULL NUMBER(6) ORDER_STATUS NUMBER(2) ORDER_TOTAL NUMBER(8,2) SALES_REP_ID NUMBER(6) PROMOTION_ID NUMBER(6) This oe.orders is just a table in the example schema of OE so this colums can be dropped. So please dont install sample schemas if you dont need them. SQL--- alter table OE.ORDERS drop column ORDER_DATE ; Table altered. Now the Time Zone can be altered using above command. Step 4: Also check the value of " SELECT SESSIONTIMEZONE FROM DUAL; " and if the value differs from os time zone, db time zone , emd.properties / agent time zone then also set it according to your timezone but I believe it always gives the OS time zone. Step 5: Stop and Restart all Services and check that Oracle DBConsole service is running or not and if not running then start from command prompt " emctl start dbconsole" . https://hostname:1158/em/
