This document discusses various methods for moving data in and out of Oracle databases, including:
1) Using SQL*Loader to load data from files into Oracle tables, external tables to access file data, and Oracle Data Pump for full database exports and imports.
2) Oracle Data Pump allows high-speed movement of data and metadata and can be called from the command line or Enterprise Manager. It supports features like parallel processing, encryption, and fine-grained object selection.
3) Methods like SQL*Loader and external tables read data from files while Data Pump uses the direct path API for fast loading and unloading of data directly to and from disk.
Data Pump is a utility that replaces Oracle's traditional Export and Import utilities. It allows moving of data and metadata between Oracle databases in a fast, parallel and non-disruptive manner. Key advantages of Data Pump include parallelism for improved performance, resumability if jobs fail, the ability to remap tablespaces and datafiles, and full support for advanced Oracle database features. Data Pump operations involve a master control process that coordinates worker processes to perform parallel loading and unloading of data.

Database-Migration and -Upgrade with Transportable TablespacesMarkus Flechtner
This document discusses using transportable tablespaces (TTS) to migrate a large telecommunications database from HP-UX to Linux with an Oracle upgrade. Key points:
- The customer has 4 databases totaling over 15TB that need to be migrated with downtime under 6 hours. TTS was chosen for the migration.
- Tuning efforts included resizing files, compression, and parallelizing file transfers and conversions across RAC nodes.
- Challenges included long metadata export times. The issue was addressed by splitting exports across multiple self-contained tablespace subsets in parallel.
- Automation scripts were created to coordinate the distributed migration work across RAC nodes.
Things released by Data Pump Export Application can be brought in into a data source using Details Push Transfer Application. The following explains how to use Details Pump Export Application to import objects
The document discusses transporting a single partition of a table between Oracle databases using Oracle Data Pump. It provides steps to create test tablespaces and a partitioned table with two partitions stored in different tablespaces.

This demonstrates using Data Pump to transport a single table partition between databases for improved efficiency over full table transports.
Fortran & Link with Library & Brief Explanation of MKL BLASJongsu "Liam" Kim
This document discusses Fortran programming best practices and features. It recommends avoiding labeled DO loops, EQUIVALENCE, and COMMON blocks due to errors and complexity. Instead, it suggests using CYCLE and EXIT statements, WHERE constructs, and DO CONCURRENT for vectorization. The document also covers sparse matrix storage formats and using Intel MKL and BLAS routines for linear algebra operations.
This document discusses file size limits in Oracle databases. The 2GB file size limit arises because many systems use 32-bit integers to represent file sizes, which can only address up to 2GB of data. Using files larger than 2GB requires operating system and Oracle database versions that support 64-bit file APIs. The document outlines issues with tools like Export and SQL*Loader not fully supporting large files and provides platform-specific guidance.

Oracle api gateway installation as cluster and single nodeOsama Mustafa
Oracle API Gateway can be configured as a cluster on Solaris SPARC. The documentation explains how to install API Gateway on two nodes and configure them as a cluster. Key steps include modifying the /etc/host files on each node to include both, extracting and running the installation files on each node as the Oracle user, and registering the second node while specifying the first node as the Admin Node Manager. The process generates certificates and adds the nodes to the topology. Starting the Node Manager on each node completes the basic cluster configuration.
The document provides an agenda and overview for a workshop on key OpenSolaris 2009.06 technologies including installing OpenSolaris, the IPS package manager, ZFS and Time Slider, and DTrace. It discusses options for installing OpenSolaris natively, in a partition, or in VirtualBox. It also provides demonstrations of the IPS package manager, managing repositories, ZFS features like snapshots and Time Slider, and using DTrace to monitor system calls.
This document discusses whether it is possible to edit an Oracle database dump file. It explains that dump files are binary files, so editing them in a text editor will corrupt the file format. While it may be possible under some circumstances, it is not reliable. The document recommends alternative approaches like using import to extract DDL statements into a text file, editing that, and running it as a SQL script instead of directly editing the binary dump file.
Create your oracle_apps_r12_lab_with_less_than_us1000Ajith Narayanan
This document summarizes a presentation on how to create an Oracle Apps R12 lab with less than $1000. It discusses designing a multi-tier architecture for Oracle Apps R12 on a Linux platform using inexpensive hardware. Specifically, it describes how to set up 5 Dell desktops running Oracle Linux and connected via switches to act as nodes, with a NAS storage device providing shared storage between the nodes. Software components like Oracle Grid Infrastructure, Oracle Database, and Oracle E-Business Suite can then be installed to implement the multi-tier RAC configuration. The presentation provides step-by-step instructions for tasks like preparing the shared storage, installing the various Oracle software components, and configuring the applications tier to use the RAC database.
Oracle business intelligence enterprise edition 11guzzal basak
This document provides instructions for installing an interim patch for Oracle Business Intelligence Enterprise Edition 11g. It includes prerequisites for installing the patch such as downloading the latest version of OPatch. The instructions cover unzipping the patch file, setting environment variables, running OPatch to apply the patch, and verifying successful installation. Post-installation steps include starting services. Deinstallation instructions are also provided in case issues arise after installing the patch.
This document provides release notes for an Oracle Patch Set Update (PSU) certified to work with specific versions of ArcSight ESM. It lists the Oracle database versions and platforms that the October 2012 PSU has been certified for. It also provides instructions for applying the PSU, including downloading the necessary files and following Oracle's patching process. The document outlines some known issues and workarounds for applying the PSU on different platforms.
The document discusses applying a blockcentric approach to Oracle tuning, which focuses on blocks of data rather than individual rows and shifts tuning decisions based on the number of blocks accessed rather than traditional metrics like buffer cache hit ratios. It addresses myths around traditional tuning methods and provides guidance on identifying resource-intensive SQL, reducing I/O operations, maintaining tables and indexes, and determining true statement costs.
Resetting a sequence number back to its starting value can be done without dropping and recreating the sequence. The true last number issued by a cacheable sequence can be determined by directly selecting its nextval. Altering the sequence increment to a negative number of the last number will set it to 0. Selecting nextval again and then altering the increment back to normal resets the sequence to start from 1. This reset is best done in a restricted session to avoid conflicts from concurrent usage.
This document discusses creating rollback segments in locally managed tablespaces in Oracle databases. It explains that while rollback segments can be created in locally managed tablespaces, the first one must be created differently to avoid an error. It recommends creating a temporary rollback segment in a dictionary-managed tablespace first to store the rollback information needed to create the initial rollback segment in the locally managed tablespace. Once that first segment is created, additional segments can be added to the locally managed tablespace.
