Oracle Forms is a software product for creating screens that interact with an Oracle database. It has an IDE including an object navigator, property sheet and code editor that uses PLSQL. It was originally developed to run server side in character mode terminal sessions. It was ported to other platforms, including Windows, to function in a clientserver environment. Later versions were ported to Java where it runs in a Java EE container and can integrate with Java and web services. The primary focus of Forms is to create data entry systems that access an Oracledatabase. How it workseditOracle Forms accesses the Oracle database and generates a screen that presents the data. The source form. The form is used to view and edit data in database driven applications. Various GUI elements, such as buttons, menus, scrollbars, and graphics can be placed on the form. Youre currently subscribed to some eWEEK features and just need to create a username and password. Can you apply patch without putting Applications 11i in Maintenance mode Ans Yes, use optionshotpatch as mentioned above with adpatch. Source code may also be placed in library files The environment supplies built in record creation, query, and update modes, each with its own default data manipulations. This minimizes the need to program common and tedious operations, such as creating dynamic SQL, sensing changed fields, and locking rows. As is normal with event driven interfaces, the software implements event handling functions called triggers which are automatically invoked at critical steps in the processing of records, the receipt of keyboard strokes, and the receipt of mouse movements. Different triggers may be called before, during, and after each critical step. Each trigger function is initially a stub, containing a default action or nothing. Programming Oracle Forms therefore generally consists of modifying the contents of these triggers in order to alter the default behavior. Some triggers, if provided by the programmer, replace the default action while others augment it. As a result of this strategy, it is possible to create a number of default form layouts which possess complete database functionality yet contain no programmer written code at all. HistoryeditOracle Forms is sold and released separately from the Oracle Database. However, major releases of an Oracle database usually result in a new major version of Oracle Forms to support new features in the database. Original VersioneditOracle Forms started as Interactive Application Facility IAF, which had two main components the compiler Interactive Application Generator IAG and the runtime interpreter Interactive Application Processor IAP. Released with Oracle Database version 2, IAF provided a character mode interface to allow users to enter and query data from an Oracle database. It was renamed to Fast. Forms with Oracle Database version 4 and added an additional tool to help generate a default form to edit with IAG, the standard tool. The product saw one more name change before gaining its current moniker, called SQLorms version 2 with the Oracle 5 database. Forms 2. xeditOracle Forms 2. PLSQL. The source file was an INP ASCII file, which meant it could be edited directly. This version used its own primitive and unfriendlyaccording to whom built in language, augmented by user exitscompiled language code linked to the binary of the Oracle provided run time. Forms 3. xeditOracle Forms 3 was character based, and by using PLSQL was the first real version of Forms. All subsequent versions are a development of this version. It could run under X but did not support any X interface specific features such as checkboxes. The source file was an INP ASCII file. The IDE was vastly improvedaccording to whom from 2. INP file directly, though this was still a common practice. Forms 3 automatically generated triggers and code to support some database constraints. Constraints could be defined, but not enforced in the Oracle 6 database at this time, so Oracle used Forms 3 to claim support for enforcing constraints. There was a GUI version of Forms 3 which could be run in environments such as X Window, but not Microsoft Windows. This had no new trigger types, which made it difficult to attach PLSQL to GUI events such as mouse movements. Forms 4. xeditOracle Forms version 4. GUI based version of the product. A character based runtime was still available for certain customers on request. The arrival of Microsoft Windows 3 forced Oracle to release this GUI version of Forms for commercial reasons. Forms 4. 0 accompanied Oracle version 6 with support for Microsoft Windows and X Window. This version was notoriously buggy and introduced an IDE that was unpopular with developers. The 4. FMB. This version was not used by the Oracle Financials software suite. Oracle Forms version 4. It contained significant functional changes and a brand new IDE, replacing the unpopular IDE introduced in 4. It is believedaccording to whom to be named 4. Forms 4 for a period of time for certain clients. It added GUI based triggers, and provided a modern IDE with an object navigator, property sheets and code editor. Forms 5. xeditDue to conflicting operational paradigmswhich, Oracle Forms version 5 accompanied Oracle version 7. It featured custom graphical modes tuned especially for each of the major systems, though its internal programmatic interface remained system independent. Forms 6. xeditForms 6 was released with Oracle 8. Forms 6i with Oracle 8i. This version was basically Forms 4. It included the facility to run inside a web server. A Forms Server was supplied to solve the problem of adapting Oracle Forms to a three tier, browser based delivery, without incurring major changes in its programmatic interface. The complex, highly interactive form interface was provided by a Java applet which communicated directly with the Forms server. However the web version did not work very well over HTTP. A fix from Forms 9i was retrofitted to later versions of 6i to address this. The naming and numbering system applied to Oracle Forms underwent several changes due to marketing factors, without altering the essential nature of the product. The ability to code in Java, as well as PLSQL, was added in this period. Forms 7. xeditForms 7 was never released to the public and only existed internally as Project Cherokee. Forms 8. Version 8 did not exist this version number was jumped over in order to allow the Oracle Forms version number to match the database version in v. Forms 9. xeditForms 9i included many bug fixes to 6i and was a stable version, but it did not include either clientserver or character based interfaces, and three tier, browser based delivery is the only deployment option. The ability to import java classes means that it can act as a web service client. Forms 1. 0. xeditForms 1. Forms version 9. 0. Forms 9i. Forms 1.

Oracle slow SQL query against dbasegments solved. July 1. 8, 2. 01. Kirill Loifman I remember when long time ago one database consultant confused my manager saying that our Oracle 9i database had poor performance just taking into account a slow response from dbasegments data dictionary view. That was a nasty trick to blame a DBA and the Oracle database for poor performance at that time. In fact there were a few Oracle bugs related to those performance issues after switching from dictionary to locally managed tablesspaces at that time. Recently Ive noticed similar performance degradation on Oracle 1. R2 1. 1. 2. 0. 2 and 1. DBASEGMENTS or USERSEGMENTS data dictionary views involving the columns BYTES, BLOCKS, or EXTENTS. Queries on DBATSQUOTAS or USERTSQUOTES on columns BYTES or BLOCKS were also slow. Even if you personally do not care about these dictionary views they are still very important since they are used by some Oracle internal components and the other database tools including Oracle Enterprise Manager OEM Cloud Control and its Database Home Page. Thus, Ill describe below the problematic of those data dictionary views and the way how to fix their performance issues. First of all do not wonder why queries against those views often seem to slow. DBASEGEMENTS for example is a very complex view that is built on another SYSDBASEGS view. In summary DBASEGMENTS view on Oracle 1. R2 consists of the following components 2. SQL code 3 UNION ALL clauses A lot of joins between following tables sys. The main performance problem here however is that the values of the BYTES, BLOCKS EXTENTS columns of the DBAUSERALLSEGMENTS and DBAUSERALLEXTENTS views are not stored in the Data Dictionary for segments that reside in Locally Managed Tablespaces. Instead they must be obtained by accessing the Segment Header Blocks for all segments processed in the query. These extra block accesses cause the slow performance. So with increasing number of database files and segments the query performance in this case can potentially degrade. Furthermore Oracle in certain circumstance does not cache properly those segment header blocks, thus forcing reading them from disk even at the next query run so no caching happening. Do not be surprised if I say that a query against dbasegments can trigger even at the background a few more procedures from DBMSSPACEADMIN package to get correct segment sizing information. All in all, the symptoms of performance degradations with these dictionary views can vary. In my last case they were even different on different database platforms. If you encounter similar performance issues I strongly recommend contacting Oracle support. Additionally Ill share below how I fixed my last case on Oracle 1. Check if you have slow segments on your database with slow dbasegments, dbaextents, etc. DECODEbitandsegmentflags,1. ROLLBACK, DEFERRED ROLLBACK, TYPE2 UNDOgroup by tablespacenamehaving sumDECODEbitandsegmentflags,1. If you see thousands of segments this can lead to poor query performance. In case you see a few of them, even hundreds, I would keep monitoring further with the same SQL to see if the number of slow segments increases. If case of one of the above or both, go to next steps. Ensure you apply an Oracle Patch for a Bug 1. SEG not updated after adding an extent. Based on Oracle, the Bug is fixed in the following database versions 1. Base Release1. 1. Server Patch Set1. Database Patch Set Update. Bundle Patch 1. 4 for Exadata Database. Patch 1. 3 on Windows Platforms. Patch 2. 3 on Windows Platforms. Note, that in my case however patching a database to Oracle 1. R2 1. 1. 2. 0. 3. Itanium HP UX platform. I could fix it only with 1. After applying the patch, you can run the following PLSQL block as sysdba which corrects sizing information on the segments beginfor t in select distinct tablespacenamefrom sys. ROLLBACK, DEFERRED ROLLBACK, TYPE2 UNDOand tablespacename SYSTEMloopdbmsspaceadmin. Its advisable to take a database backup before the above SQL execution. Additionally I would not run that SQL against SYSTEM tablespace thats why SYSTEM is excluded in the SQL unless its recommended by Oracle Support. So that was a few insides in Oracle slow segments issue and the troubleshooting example of slow SQL query performance against dbasegements view on Oracle database 1. R2.
