The following Recovery manager script is a backup of data files to a tape drive controlled by the media Manager: Run {# allocating a channel of type ' SBT ' for s Erial deviceallocate CHANNEL ch1 DEVICE TYPE SBT; BACKUP datafile 3;} When Recovery Manager executes the command, the backup request is sent to the Oracle DB session that performed the backup. The oracle DB session identifies the output channel

Standalone application (self-contained applications)Now, based on a simple app, write a standalone application through the Spark API. Programs written in Scala need to be compiled and packaged using SBT, and Java programs are packaged using Maven, and Python programs are submitted directly via Spark-submit.PS: As if the spark2.0 supports a data set (DataSets) other than the RDD, the performance of Python processing is greatly improved, almost compara

Library:Sbt_libraryParameters When you allocate or configure channels for RMAN to communicate with the Media Manager, you need to set the sbt_library parameter to provide the media management software library. During actual RMAN execution, the database in sbt_library will be loaded. If this value is not set, it will be searched in the default location of the platform, $ ORACLE_HOME/lib/libobk. so, the suffix may be. SL ,. A and so on. It is % ORACLE_HOME %/bin/orasbt in windows.

RMAN Channels RMAN executes all backup and recovery activities, which are Server sessions on the target database instance. Each session on the server used by RMAN is calledRMAN Channel. A channel can be used for disk operations.Disk ChannelOr one that is used together wi

Eclipse is a very useful development tool, and the kids ' shoes that are familiar with it should know that it is not only the most commonly used Android development tool , but also the most common Java development tool. Since eclipse is so important, the small part of this article will be together with you to pick up the knowledge of building a Scala development environment in Eclipse, interested children shoes can come together to see.1 , Scala is whatIn fact, Scala is a syntax, similar to Java

You are welcome to reprint it. Please indicate the source, huichiro.Summary The previous blog shows how to modify the source code to view the call stack. Although it is also very practical, compilation is required for every modification, which takes a lot of time and is inefficient, it is also an invasive modification that is not elegant. This article describes how to use intellij idea to track and debug spark source code.Prerequisites This document assumes that the development environment is on

Quick StartThis article describes how to use scala, java, and python to compile a spark click Mode Program. First, you only need to successfully build Spark on a machine. Practice: Enter the Spark root directory and enter the command: $ sbt/sbt package(Because of the Great Firewall of tianchao, the mainland China cannot succeed, unless you can smoothly flip the wall).
