XML: XML is an acronym for ‘Extensible Markup Language’. It is used for defining data
elements on a webpage and business to business document. XML uses a similar tag
structure as HTML; however, whereas HTML defines how the elements are displayed,
XML defines what those elements contain.
Manually database creation is one of the more frequently performed actions of a professional DBA. And, with Oracle 11g it only takes a few minutes to do :)
The procedure is same as previous which we are used for 9i and 10g.
In this database creation I used below features:
1. OMF (Oracle Managed File) for datafiles, redolog files & controlfiles
2. FRA (Flash Recovery Area) for Archivelog or backup files
3. ASM (Automatic Storage Mgmt) for Volume manager
1. Create Required Directories
Before commencing to read this article, I would suggest you to go through the Oracle Database Architecture ( Oracle Database Architecture ) Article to gain insight about the oracle various structures.
The following example describes the most basic level of operations that Oracle performs.
Oracle PL/SQL Server Pages (PSP) is Oracle's PL/SQL dynamic server-side scripting solution for Web application development. Oracle PSP includes the PL/SQL Server Pages Compiler and the PL/SQL Web Toolkit. Oracle PSP enables PL/SQL users to develop Web pages with dynamic content by embedding PL/SQL scripts in HTML. PSPs separate application logic (embedded PL/SQL scripts) from the layout logic (HTML) making the development and maintenance of PL/SQL Server Pages easy.
Well, just for a briefing, since 1966, most of the United States has observed Daylight Saving Time from at 2:00 a.m. on the first Sunday of April to 2:00 a.m. on the last Sunday of October. But in 2007, most of the U.S. will begin Daylight Saving Time at 2:00 a.m. on the second Sunday in March and revert to standard time on the first Sunday in November.
So, Oracle has released patches to adapt these Daylight saving time changes. The databases that are using the following will be impacted…
1. Databases using TIMESTAMP WITH TIME ZONE and TIMESTAMP WITH LOCAL TIME ZONE data types and TZ_OFFSET function as they take their time zone information from Oracle's time zone files.
Recently Performance Tuning compared Oracle 10gR2 RAC on Windows Server 2003 x64 vs. RHEL. You can download the paper from microsoft-oracle.com
The following behavior was observed during testing of the Oracle RAC databases on Red
Hat Enterprise Linux x86_64 and Microsoft Windows Server 2003 Enter:
Oracle RAC Stress Test
o Transactions Per Minute were roughly equivalent for 2 - 150 user sessions.
o Transactions Per Minute were up to 16% higher for MS Windows for 150
- 250 users.
o CPU usage was above 90% for all of these tests for both Linux and MS
o The response times for the “New Company Registration” test component
I have never joined an Oracle forum before so hello.
I have just spent the last 9 years of my life working for Oracle Consulting UK. I am now contracting in the Cayman Islands.
I spent a lot of time writing a shell script and wondered if you'd like to see it. it really can save you a lot of time and is a nice cockpit to navigate around in.
works great for no database, core, or 11i (eBus)
tell me what you think:
it only runs on unix (ksh) or bash with a very simple documented mod. I even coded it around pdksh's bugs (rightmost pipe not in current process).
Often, we want our PL/SQL code to output messages (using DBMS_OUTPUT) to debug a problem. This is mostly required during development, but may also come in handy if a program misbehaves in production. If the testing of your application is thorough, then you should never have an issue in the production environment. But, we all know that there are instances where we do want debug messages even in the production environment. Before Oracle 10g R2, this could not be done dynamically.
