Oracle Edq Latest Version
Eberardo Topher
It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database workloads. Oracle Database is available by several service providers on-premises, on-cloud, or as a hybrid cloud installation. It may be run on third party servers as well as on Oracle hardware (Exadata on-premises, on Oracle Cloud or at Cloud at Customer).[5]
Larry Ellison and his two friends and former co-workers, Bob Miner and Ed Oates, started a consultancy called Software Development Laboratories (SDL) in 1977. SDL developed the original version of the Oracle software. The name Oracle comes from the code-name of a CIA-funded project Ellison had worked on while formerly employed by Ampex.[7]
Oracle products follow a custom release-numbering and -naming convention. The "ai" in the current release, Oracle Database 23ai, stands for "Artificial Intelligence". Previous releases (e.g. Oracle Database 19c, 10g, and Oracle9i Database) have used suffixes of "c", "g", and "i" which stand for "Cloud", "Grid", and "Internet" respectively. Prior to the release of Oracle8i Database, no suffixes featured in Oracle Database naming conventions. There was no v1 of Oracle Database, as co-founder Larry Ellison "knew no one would want to buy version 1".[8] For each database release, Oracle also provides an Express Edition (XE) that is free to use.[9]
Prior to Oracle Database 18c, Oracle Corporation released Critical Patch Updates (CPUs) and Security Patch Updates (SPUs)[33] and Security Alerts to close security vulnerabilities. These releases are issued quarterly; some of these releases have updates issued prior to the next quarterly release.
Starting with Oracle Database 18c, Oracle Corporation releases Release Updates (RUs) and Release Update Revisions (RURs).[34] RUs usually contain security, regression (bug), optimizer, and functional fixes which may include feature extensions as well. RURs include all fixes from their corresponding RU but only add new security and regression fixes. However, no new optimizer or functional fixes are included.
In the market for relational databases, Oracle Database competes against commercial products such as IBM Db2 and Microsoft SQL Server. Oracle and IBM tend to battle for the mid-range database market on Unix and Linux platforms, while Microsoft dominates the mid-range database market on Microsoft Windows platforms. However, since they share many of the same customers, Oracle and IBM tend to support each other's products in many middleware and application categories (for example: WebSphere, PeopleSoft, and Siebel Systems CRM), and IBM's hardware divisions work closely[citation needed] with Oracle on performance-optimizing server-technologies (for example, Linux on IBM Z). Niche commercial competitors include Teradata (in data warehousing and business intelligence), Software AG's ADABAS, Sybase, and IBM's Informix, among many others.
Increasingly, the Oracle database products compete against open-source software relational and non-relational database systems such as PostgreSQL, MongoDB, Couchbase, Neo4j, ArangoDB and others. Oracle acquired Innobase, supplier of the InnoDB codebase to MySQL, in part to compete better against open source alternatives, and acquired Sun Microsystems, owner of MySQL, in 2010. Database products licensed as open-source are, by the legal terms of the Open Source Definition, free to distribute and free of royalty or other licensing fees.
When you connect to an Oracle database, you may need to know the exact version and edition you are connecting to, either to take advantage of fancy new features, or to limit yourself to legacy behavior. In this article we are going to review how to obtain that information.
I built Beekeeper Studio because, like Allan, I wanted something more intuitive and modern than all the existing clunky apps I could find. My customers agree - they love using Beekeeper and they tell me every day! Give it a try, I bet you'll like it too.
Like most software products, Oracle Database is constantly evolving, adding new features and fixing issues. In order to be able to identify with precision each product, Oracle uses a numbering convention that allows to identify them.
Oracle Database products until 2018 were identified with a sequence of 4 numbers. The first representing the major-version, which incremented on substantial changes. The second referenced the release, a release was created when new features were included but without a major rewriting of the software. The third and fourth numbers represented patch-sets, which were essentially bug fixes.
Since 2018, Oracle changed the numbering convention. The first number or version is the year in which the product is released. The second number represents the quarterly update, and the third represents the quarterly revision. You can check the Database Upgrade Guide to learn more about them.
While versions represent the evolution of Oracle Database engine development, there are also different editions of the product. The different editions include different features that allow Oracle to segment the market and charge more money for more advanced features.
The view PRODUCT_COMPONENT_VERSION includes information about the Oracle Database and additional components installed. It has four columns, and contains information on the product name, Edition, base version, full version, and the status of the release.
In this example, since we are connecting from a computer where the Oracle client has not been updated, we will see that the SQL*Plus version reported is 19.3.0.0 (shown in the second line), while the database we are connecting to is 19.14.0.0 (shown in the sixth line).
There may be situations where we cannot connect to the database, for example after a server failure that does not allow the database to be started. In such scenarios, if we do have access to the database server we can read the alert log file. This file contains information about important events and issues, including startup or shutdown requests. After each startup request you will see some lines like this.
background:
We get a random and seemingly irreproducible error saying "invalid number" when saving data (we guess it's the Timestamp). But it's not any particular statement. Most of the time, it saves just fine. Just once a month a harmless looking statement will fail.
Our product is run on databases maintained by our clients, i.e. whatever version and patch the clients have running is what it is.
So what driver do we use? The latest (Oracle 11g) - despite the fact that it's usually 9i and 10g databases?
The numbers in ojdbc14.jar, ojdbc5.jar, ojdbc6.jar, ojdbc7.jar and ojdbc8.jar refer to the version of the Java compiler that was used. With every version of Java come new JDBC APIs so these numbers are useful to know what to expect. For example in Java 8, there is a new method executeLargeUpdate in java.sql.PreparedStatement. This method will be implemented in ojdbc8.jar but not in ojdbc7.jar. Also if your runtime uses Java 7 then you know you can't use ojdbc8.jar otherwise you'll run into a java.lang.UnsupportedClassVersionError error. These are the reasons why Oracle includes these numbers in the jar's name. Also note that if you want to know from which Oracle Database release the jar comes from you can run java -jar ojdbc8.jar. Both the Database and the driver are backward compatible (up to 1 major release) so, even though it's recommended, you don't have to use the same version of the product on both tiers.
When we upgraded our Oracle database from 8.1.7 to 10.2.0, I was able to use the same Oracle jdbc driver (ojdbc14.jar). So their jdbc driver supports quite a few versions at the same time. Of course it's possible that some of the drivers are buggy, but the plan is to support more versions at the same time.
This comes into play if you have more than one client installed on the machine so this could be part of your issue. If so, the simple thing to do is use the dllPath configuration variable in your config:
Now, to answer your question directly - I don't believe Oracle supports mismatching Oracle.DataAccess.dll with it's client (at least not backwards). Your best bet is either to install ODP.net with your app install - the xcopy version is the smallest and contains the "instant client" Or, you should be thinking about minimum system requirements - ie. The system must have at least version X of odp.net installed. You could then compile against that minimum dll and rely on publisher policy redirection when a target system has a NEWER version of the client.
Of course this also prompts me to ask about architecture. Do you plan on prompting the user for their Oracle account? If not, you have to be careful on how you protect the shared service account your application will use. You may be better off making calls to a webservice that makes the oracle calls on the clients behalf - giving you another security layer and simplifying your client deployment.
First of all clarification: You have an Oracle Database Server (you called it "back end oracle database") and an Oracle Client (no matter if this is installed on an application server, from Oracle point of view, it is the client)
The version of ODP.NET (Oracle Data Provider for .NET, i.e. the Oracle.DataAccess.dll and some more files) are defined by the Oracle Client. You can use almost every ODP.NET version to connect to every Oracle database version - more or less.
The error message "The provider is not compatible with the version of Oracle client" could also mean there is no ODP.NET provider installed at all. In this case the error message is indeed a bit misleading. So, first check if ODP.NET is installed at all, it is not included in standard Oracle Instant Client installation.
9.? and 10.? refers to version of Oracle, 1.x, 2.0 and 4.0 refers to version of Microsoft .NET Framwork (strange numbering, but that's how it is). Version 9.? and 10.? are very old, I don't think it makes any sense to use them. 1.x was supported until Oracle client version 11.1.
