This type of installation is suited best for users who want to upgrade Forms applications to the Grid environment in two phases. In phase one, they move to the Grid environment by upgrading their client server based Forms applications to Web-based ones. In phase two, users can then choose to use the services offered by an existing Oracle Application Server Infrastructure installation.
Oracle Server 10g
Oracle Application Server Forms Services deploys Forms applications with database access to Java clients in a Web environment. Oracle Application Server Forms Services automatically optimizes class downloads, network traffic, and interactions with Oracle database. Applications are automatically load-balanced across multiple servers and, therefore, can easily scale to service any number of requests.
Oracle HTTP Server is the Web server that Oracle Application Server uses, which is built on Apache Web server technology. Oracle HTTP Server offers scalability, stability, speed, and extensibility. It also supports Java servlets, Java Server Pages (JSPs), Perl, PL/SQL, and CGI applications.
Oracle Application Server Web Cache is a server accelerator caching service that improves the performance, scalability, and availability of frequently used Oracle E-business Web sites that run on the Oracle platform. By storing frequently accessed URLs in virtual memory, Oracle Application Server Web Cache eliminates the need to repeatedly process requests for those URLs on the Web server, and it caches both static and dynamically-generated HTTP content from one or more applications Web servers.
Application Server Control provides Web-based management tools designed specifically for Oracle Application Server. Using Application Server Control, you can monitor and configure components of your application server. You can deploy applications, manage security, and create and manage Oracle Application Server clusters.
The Enterprise Manager Home pages you use to manage Oracle Application Server and its components: These Web pages provide you with a high-level view of your Oracle Application Server environment. From these pages you can drill down for more detailed information on administration, configuration, and performance monitoring. These pages allow you to administer the application server and its components and deployed applications.
The underlying software technologies that keep track of your application server instances and components: These technologies automatically perform many management tasks. For example, they discover the components of each application server instance, gather and process performance data, and provide access to application configuration information.
Oracle Process Manager and Notification Server (OPMN) provides process control and monitoring for application server instances and their components. It gathers component status information, and distributes the status information to components that are interested in it. The Application Server Control uses OPMN for such tasks as starting and stopping the components of your application server instance.
Distributed Configuration Management (DCM) manages configurations among application server instances that are associated with a common Metadata Repository. It enables Oracle Application Server cluster-wide deployment so you can deploy an application to one instance and have it automatically propagated to the entire cluster. You can also make a single host or instance configuration change to one instance and have it propagated across all instances in the cluster. Application Server Control uses DCM to make configuration changes and to propagate configuration changes and deployed applications across the cluster.
Oracle Corporation marketed its first application server using the name Oracle Web Server (OWS).[2]A subsequent repackaging resulted in the Oracle Application Server (OAS).[3]A later product, superseding OAS, became the iAS (Internet Application Server).[4]
In this article I'll describe the installation of Oracle Application Server 10g (9.0.4), Oracle's J2EE Application Server, on Fedora Core 2. The article assumes you've performed the standard server installation including the development tools.
In this article I'll describe the installation of Oracle Application Server 10g Release 3 (10.1.3), Oracle's J2EE Application Server, on RedHat Advanced Server and CentOS. The article is based on a server installation with a minimum of 2G swap, secure Linux disabled and the following package groups installed.
DearsAfter wishing you a good day , i've a situation were my client has a legacy application deployed on oracle application server 10G on windows server 2003 , the application server communicates with oracle database 10G on windows server 2003 as well .
our mission is to move the 10G database to 19C without upgrading the application server as the legacy application won't be working on any other weblogic release . anyway i managed to install the new 19C database and move the business schemas to the new database and now stuck in making communication with the new database , after some invastigations we found that the application logs aren't accurate due to code problems .
1st ) is it possible to make oracle application server communicate with the database with the huge differences between the jdbc ?2nd ) is there a way to test the datasource connections on the oracle application server " i can't find any "3rd ) is there any proper documentations on oracle application server as i can't find much of the server/application logs i have to rely on the errors that pop ups ?
When a user launches a new Oracle Forms application, the application first invokes the FormsServlet class to initiate connection. The application then invokes the ListenerServlet class, which launches frmweb process in the background of the remote server.
The Oracle Forms application does not perform adequate input validation on the logfile parameter and allows directory traversal sequences (../). By controlling the ifip parameter passed to the ListenerServlet class, an attacker can now control the logfile location and partially its content as well. Combined with the weak configuration of the remote web server that allows jsp files to be served under :port/forms/java location, attacker could upload a remote shell and execute arbitrary code on the server.
The web server does not seem to accept white spaces or new lines; it also limits the number of characters that could be passed onto the frmweb executable. To execute Operating System command, a custom JSP shell was developed that bypass such restrictions.
Oracle Forms 10g is also vulnerable to a simple DOS attack: each time the URL :8889/forms/lservlet?ifcfs=/forms/frmservlet?acceptLanguage=en-US,en;q=0.5&ifcmd=getinfo&ifip=127.0.0.1 is invoked, a frmweb process will be launched in the background. An attacker could exhaust server resources simply by requesting the same URL multiple times. I believe this behavior is fixed in version 11g and onwards with connection pooling
Long before Java or application servers existed, there was already aneed to servicetransactions betweendistributed systems. The transactionmonitor was originally created to provide atwo-phase commit , assuring that transactions were madereal only when committed on two different platforms. Examples ofearly transaction monitors that gained popularity include CICS (fromIBM) and Tuxedo (originally developed by AT&T and later acquiredby BEA). Tuxedo first appeared in 1983 and evolved from simplyguaranteeing reliable transactions to also providing a middle tierfor offloading the workload from transaction-processing databases.Use of the middle tier enabled the database to support many moretransaction-processing users at higher performance levels.
Thus, the Internet computing model created another market formiddleware at the same time that Javagained popularity for Internet programming. The natural evolution ofapplication servers toward serving and supporting Java-basedapplications began. Several providers of early transaction monitorsmerged their middleware offerings into new application serverpackaging.
Early Oracle database implementations were commonly deployed onminicomputers, and many customers began to explore using distributeddatabases utilizing several of these relatively inexpensiveplatforms. At about the same time that the first application serversappeared to manage these configurations for transactions, Oraclebegan building distributed features in the database for handlingdistributed queries and two-phase transactional commits. AlthoughOracle was building such capabilities in the database, populartransaction-processing monitor support was added through interfacessuch as XA to enable greater scalability and ensure the portabilityof such applications to the Oracle database.
According to Oracle forums, this is defined in Metalink DocID 207303.1, which provides a comprehensive client/ server compatibility matrix. I don't have Metalink access sadly, so I can't confirm this.
Problem: We would like to upgrade to SQL Server 2014 SP1 (with Oracle 12c Client) and still pull data from the Oracle 10g server. We have run some test on returning the data using OPENQUERY and the results are less then satifactory. A simple select * from a table went from 9seconds to 54 seconds!
Testing: We created a test SQL Server 2008 R2 server but this time put Oracle 12c client on it. The select * query ran in 26seconds this time but still alot longer then the 9 from the original server.
As Oracle support note "Client / Server Interoperability Support Matrix for Different Oracle Versions" ( Doc ID 207303.1 ), Oracle Client 12.1 does not support connections with Oracle DB servers 10.1 and below.
When using Oracle 10g high CPU utilization may occur on the DBMS server (the server node running Oracle 10g).For example, after upgrading from Oracle 9i to Oracle 10g, a system's administrator may notice an increase in the CPU utilization on the server when there has been no change in the application or typical workflow being performed by the organization. The behavior can be noticed when working with versioned classes using either the ArcSDE application server or direct connect. The CPU usage is dependent on the number of concurrent users executing queries. Some users may not notice the increased CPU usage, solely based on the number of users accessing the Oracle server. 2ff7e9595c
