Detail of Patches in Oracle apps

As you all know, we have to apply patches very frequently .This may be on your database or for oracle application ERP.

We use OPATCH to apply patches on database and ADPATCH to apply patches on oracle apps.

Here I am discussing only about ADPATCH. As till now I have worked in many organizations and applied number of patches in different environments. So I am sharing my knowledge with you all. And if you find any mistake please feel free to write.

What is patch ?

In simple words patches are used to fix a bug. A bug is a defect in the code or functionality. Oracle provide solution for that particular bug known as patch.

Types of patches in oracle apps?

Standalone/Oneoff patches :-- This is used to define patch created to fix single/particular problem.

Mini Pack :--This is group of oneoff patches for a particular product like INV, GL, AP and named like 11i.GL.E ( means this group of patches contain fix for 11i GL product (General Ledger till time E is released ) This is cummutative which means it will include 11i.GL.A, 11i.GL.B ....11iGL.D till 11i.GL.E earlier in 10.7 it used to called as patchset.

Family Pack :-- Group of mini packs in one family buldeled together is called as family pack. they are usually named as 11i_PF. Few example of falilies are SCM ( 11i.SCM_PF.G ), ATG ( 11i.ATG_PF.H ) _PF indicate Product Family Pack

Maintenance Pack :-- Group of family pack together is called as maintenance pack. So if you say your Verison is 11.5.10 then its maintenance pack 10 ( 3rd digit is maintenance pack )

cXXXXXX.drv The copy driver. Similar to patch.drv except it does not generate any files. dXXXXXX.drv Database driver. Functions the same as the R10 database driver.
gXXXXXXdrv Generate driver. Generates forms, reports, libraries, and message files.
uXXXXXX.drv it is combination of all patches. means it contain c,d,g patch work.

What is adpatch?

It is a utility which is used to apply patches.

DBA_SCHEDULER_JOB_RUN_DETAILS and PURGE_LOG

How to purge DBA_SCHEDULER_JOB_RUN_DETAILS? Manually deleting from DBA_SCHEDULER_JOB_RUN_DETAILS is not recommended by oracle.DBA_SCHEDULER_JOB_RUN_DETAILS is a view that is using two master tables (scheduler$_job_run_details and scheduler$_event_log) and display the information about jobs history. As there is one procedure named PURGE_LOG and Oracle have Scheduler for this procedure. It will purges all rows in the job log that are older than 30 days.This is the default behavior of this procedure. You can change this to any number of days you want by setting the attribute "SET_SCHEDULER_ATTRIBUTE". e.g. exec DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE('log_history','15'); It will purge all logs older than 15days and it will maintain the history of 15days. But If you want manually purge these logs, you can use below solution:- exec DBMS_SCHEDULER.PURGE_LOG(log_history => 15, which_log => 'JOB_LOG'); It will purge all entries from the jog log that are o...

Oracle character AL32UTF8

The character set determines what languages can be represented in the database. Oracle recommends using Unicode (AL32UTF8) as the database character set. AL32UTF8 is Oracle's name for the UTF-8 encoding of the Unicode standard. The Unicode standard is the universal character set that supports most of the currently spoken languages of the world. The use of the Unicode standard is indispensable for any multilingual technology, including database processing. Changing the database character set is a time consuming and complex project. Therefore, it is very important to select the right character set at installation time. If the language is American English or a Western European language, then the default character set is WE8MSWIN1252. Each Microsoft Windows ANSI Code Page can store data from only one language or a limited group of languages, such as only Western European, or only Eastern European, or only Japanese. AL32UTF8 is a multibyte character set, database operations on character...

ORA-02291: integrity constraint violated - parent key not found

“Error: ORA-02291: integrity constraint violated - parent key not found” Reason: A Primary key does not have the same value as the foreign key. We will discuss it in detail later in this article. Action: For ORA-02291: integrity constraint violated - parent key not found You may either delete the foreign key or the matching primary key can be added. In either way, you may try to get this error corrected. Let's understand more about ORA-02291: integrity constraint violated - parent key not found? The Oracle software brought us the strength by which multiple tables in the database can pass on information so efficiently. Not only this, there are numerous devices in this software which enables access to and sourcing data from multiple tables. You can easily execute complicated database issues without an unusual uncertainty by creating statements with the fantastic characteristic of this software. Realistically, if we talk about user or database no one is perf...
