Будут рассмотрены различные варианты кэширования результатов как sql-запросов, так и результатов хранимой в БД бизнес-логики. Произведено сравнение способов кэширования (программируемые вручную кэши, стандартный функционал) и даны рекомендации, когда и в каких случаях данные способы оптимальны, а порой опасны. ... -------- Нашли ошибку в видео?

ORACLE DBA Startup Stages
 
02:33
The Startup 'nomount' Stage When you issue the startup command, the first thing the database will do is enter the nomount stage. During the nomount stage, Oracle first opens and reads the initialization parameter file 'init.ora' to see how the database is configured. For example, the sizes of all of the memory areas in Oracle are defined within the parameter file. After the parameter file is accessed, the memory areas associated with the database instance are allocated. Also, during the nomount stage, the Oracle background processes are started. Together, we call these processes and the associated allocated memory the Oracle instance. Once the instance has started successfully, the database is considered to be in the nomount stage. If you issue the startup command, then Oracle will automatically move onto the next stage of the startup, the mount stage. Starting the Oracle Instance 'Nomount Stage' There are some types of Oracle recovery operations that require the database to be in nomount stage. When this is the case, you need to issue a special startup command: startup nomount, as seen in this example: startup nomount The Mount Stage When the startup command enters the mount stage, it opens and reads the control file. The control file is a binary file that tracks important database information, such as the location of the database datafiles. In the mount stage, Oracle determines the location of the datafiles, but does not yet open them. Once the datafile locations have been identified, the database is ready to be opened. Mounting the Database Some forms of recovery require that the database be opened in mount stage. To put the database in mount stage, use the startup mount command as seen here: startup mount If you have already started the database instance with the startup nomount command, you might change it from the nomount to mount startup stage using the alter database command: alter database mount; The Open Oracle startup Stage The last startup step for an Oracle database is the open stage. When Oracle opens the database, it accesses all of the datafiles associated with the database. Once it has accessed the database datafiles, Oracle makes sure that all of the database datafiles are consistent. Opening the Oracle Database To open the database, you can just use the startup command as seen in this example startup If the database is mounted, you can open it with the alter database open command as seen in this example: alter database open;

Using Oracle to read data from SQL Server
 
10:47
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.
