Smart Replication for Oracle SE. Dbvisit Standby is smart replication for Oracle Standard Edition.
It is built on top of the tried and proven Oracle redo/archive logging mechanism, and provides a complete tool for delivering disaster recovery databases. A Dbvisit Standby configuration consists of a primary (production) database and one or more standby (backup) databases. The primary and standby databases connect using a secure mechanism over TCP/IP, allowing databases to exist anywhere provided they can communicate with one another via TCP/IP. Paramétrage optimal pour PCTFREE, PCTUSED et INITRANS, par Tom Kyte. Cet article est la traduction d’une réponse Tom Kyte à une question sur le paramétrage idéal de PCTFREE, PCTUSED et INITRANS (L’article original en anglais se trouve ici).
Si vous avez une table qui ne subit que des inserts, mettez PCTFREE à 0, parce que vous n’avez rien à réserver pour les updates. si vous savez une table dont les lignes doublent de taille, c’est une bonne idée de mettre PCTFREE à 50, pour réserver de la place pour les updates. Vous devez comprendre comment les données grossissent dans le temps. Its All About Oracle. OCI Demonstration Programs. Oracle provides code examples illustrating the use of OCI calls.

Single Client Access Name (SCAN) is an Oracle Real Application Clusters (Oracle RAC) feature that provides a single name for clients to access Oracle Databases running in a cluster.
This chapter discusses the following concepts related to the SCAN: Overview of Single Client Access Name The SCAN is a domain name registered to at least one and up to three IP addresses, either in Domain Naming Service (DNS) or Grid Naming Service (GNS). When you use GNS and Dynamic Host Configuration Protocol (DHCP), Oracle Clusterware configures the Virtual IP (VIP) addresses for the SCAN name that is provided during cluster configuration. The node VIP and the three SCAN VIPs are obtained from the DHCP server when you use GNS. OCI Connection Pooling. The Java Database Connectivity (JDBC) Oracle Call Interface (OCI) driver connection pooling functionality is part of the JDBC client. This functionality is provided by the OracleOCIConnectionPool class. A JDBC application can have multiple pools at the same time.
Multiple pools can correspond to multiple application servers or pools to different data sources. The connection pooling provided by the JDBC OCI driver enables applications to have multiple logical connections, all using a small set of physical connections. Each call on a logical connection gets routed on to the physical connection that is available at the time of call.

Will you, won't you, will you, won't you, will you join the dance? Lewis Carroll This chapter discusses how the Oracle optimizer executes SQL statements that contain joins, anti-joins, and semi-joins. It also describes how the optimizer can use bitmap indexes to execute star queries, which join a fact table to multiple dimension tables. This chapter includes: Optimizing Join Statements To choose an execution plan for a join statement, the optimizer must make these interrelated decisions: Calcul de statistiques et mode concurrent. Beaucoup d’entre vous utilisent surement le paramètre DEGREE dans les procédures du package DBMS_STATS afin de paralléliser leur traitement de calcul de statistiques.
Mais ce que beaucoup ignorent c’est que le parallélisme ne se fait qu’au niveau du segment. Il ne peut y avoir un calcul de statistiques sur plusieurs segments à la fois. Donc, le parallélisme appliqué au calcul de statistiques n’est intéressant que lorsqu’on a affaire à de très grosses tables. ASH and AWR Performance Tuning Scripts. Listed below are some SQL queries which I find particularly useful for performance tuning. These are based on the Active Session History V$ View to get a current perspective of performance and the DBA_HIST_* AWR history tables for obtaining performance data pertaining to a period of time in the past. I would like to add that these queries have been customised by me based on SQL scripts obtained from colleagues and peers. So if I am infringing any copyright material let me know and I shall remove the same.
Also If anyone has any similar useful scripts to contribute for use by the community do send it to me and I shall include the same on this page Top Recent Wait Events. Welcome to the RPM repository on fr2.rpmfind.net. Welcome to the RPM repository on fr2.rpmfind.net rpm2html automatically generates Web pages describing a set of RPM packages. The Rpmfind tool allows automate the search of packages from the RPM Database or maintain your system up-to-date in a more automated way. The goals of rpm2html are also to identify the dependencies between various packages and to find the package(s) providing the resources needed to install a given package.
Every package is analyzed to retrieve its dependencies and the resources it offers. These relationships are expressed using hyperlinks in the generated pages.
