Holi: Symbol of love and Happiness

Happy Days Are Here Again!

"Don't Mind, It's Holi!"

Entire country wears a festive look when it is time for Holi celebration. Market places get abuzz with activity as frenzied shoppers start making preparations for the festival. Heaps of various hues of gulal and abeer can be seen on the roadside days before the festival. Pichkaris in innovative and modern design too come up every year to lure the children who wish to collect them as Holi memorabilia and of course, to drench everybody in the town.

The Festive License!
Women, especially, enjoy the freedom of relaxed rules and sometimes join in the merriment rather aggressively. There is also much vulgar behavior connected with phallic themes. It is a time when pollution is not important, a time for license and obscenity in place of the usual societal and caste restrictions. In a way, Holi is a means for the people to ventilate their 'latent heat' and experience strange physical relaxations.

Holi knows no bars, Holi knows no boundaries too. Across the world wherever Indians or people of Indian origin are present Holi is celebrated with gusto and bonhomie. People play with colours, light a bonfire called Holika and celebrate the victory of good over evil.

Well, the essence of any festival is to take a break from the daily humdrum of life and make it interesting. The other major intention of celebrating festival is to bring people together and generate a feeling of brotherhood and spread harmony all around.


Holi with friends..


The festival of colors Holi is nothing without friends, it is said on the day of Holi even the enemy becomes friend. The real charm of Holi comes with friends.

Oracle Database Startup and Shutdown Procedure

For a DBA, starting up and shutting down of oracle database is a routine and basic operation. Sometimes Linux administrator or programmer may end-up doing some basic DBA operations on development database. So, it is important for non-DBAs to understand some basic database administration activities.

How To Startup Oracle Database

1. Login to the system with oracle username

Typical oracle installation will have oracle as username and dba as group. On Linux, do su to oracle as shown below.

$ su - oracle

2. Connect to oracle sysdba

Make sure ORACLE_SID and ORACLE_HOME are set properly as shown below.

$ env | grep ORA
ORACLE_SID=DEVDB
ORACLE_HOME=/u01/app/oracle/product/10.2.0

You can connect using either “/ as sysdba” or an oracle account that has DBA privilege.

$ sqlplus '/ as sysdba'
SQL*Plus: Release 10.2.0.3.0 - Production on Sun Jan 18 11:11:28 2009
Copyright (c) 1982, 2006, Oracle.  All Rights Reserved.

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
With the Partitioning and Data Mining options
SQL>

3. Start Oracle Database

The default SPFILE (server parameter file) is located under $ORACLE_HOME/dbs. Oracle will use this SPFILE during startup, if you don’t specify PFILE.

Oracle will look for the parameter file in the following order under $ORACLE_HOME/dbs. If any one of them exist, it will use that particular parameter file.

1. spfile$ORACLE_SID.ora
2. spfile.ora
3. init$ORACLE_SID.ora

Type “startup” at the SQL command prompt to startup the database as shown below.

SQL> startup
ORACLE instance started.

Total System Global Area  812529152 bytes
Fixed Size                  2264280 bytes
Variable Size             960781800 bytes
Database Buffers           54654432 bytes
Redo Buffers                3498640 bytes
Database mounted.
Database opened.
SQL>

If you want to startup Oracle with PFILE, pass it as a parameter as shown below.

SQL> STARTUP PFILE=/u01/app/oracle/product/10.2.0/dbs/init.ora

How To Shutdown Oracle Database

Following three methods are available to shutdown the oracle database:

1. Normal Shutdown
2. Shutdown Immediate
3. Shutdown Abort

1. Normal Shutdown

During normal shutdown, before the oracle database is shut down, oracle will wait for all active users to disconnect their sessions. As the parameter name (normal) suggest, use this option to shutdown the database under normal conditions.

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

2. Shutdown Immediate

During immediate shutdown, before the oracle database is shut down, oracle will rollback active transaction and disconnect all active users. Use this option when there is a problem with your database and you don’t have enough time to request users to log-off.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

3. Shutdown Abort

During shutdown abort, before the oracle database is shutdown, all user sessions will be terminated immediately. Uncomitted transactions will not be rolled back. Use this option only during emergency situations when the “shutdown” and “shutdown immediate” doesn’t work.

$ sqlplus '/ as sysdba'
SQL*Plus: Release 10.2.0.3.0 - Production on Sun Jan 18 11:11:33 2009
Copyright (c) 1982, 2006, Oracle.  All Rights Reserved.
Connected to an idle instance.

SQL> shutdown abort
ORACLE instance shut down.

UC4 Automation Engine - An Application Manager

UC4 Workload Automation Suite has a centralized repository and interface for information collected from multiple, specialized application job schedulers automating the control and management of workload across the enterprise


The platform handles application process automation, supports hybrid computing environments, and automates any prerequisite tasks from one platform. This "ONE Automation" vision significantly reduces the cost and complexity associated with using multiple tools to perform the same tasks.

It helps all the thing into an Automated. Mostly prefer for the job scheduling task.

Automation is the most desired function in IT right now. With an ever-multiplying pile of data pouring into the world's data containers, IT managers need all the help they can get to maintain control over it all.

Benefits of UC4 Application Process Automation for Oracle®

• Reduce costs – reduce administrative overhead and eliminate delays, errors, and inaccuracies that can affect your bottom line.
• Increase agility – implement system changes in a matter of days or weeks, instead of months.
• Ensure high quality of service – proactively head off problems before they disrupt performance and meet your SLA by prioritizing tasks.

UC4 Job Scheduling:

UC4 Job Scheduling not only eliminates the need for dedicated windows to run batch jobs, but it also works across all your computing environments: on-premise, virtual, and cloud—streamlining your operations and eliminating “islands of automation.”

Benefits of UC4 Job Scheduling

• One tool – Manage jobs enterprise-wide: across all platforms, databases, applications, and computing environments.
• Schedule jobs dynamically – responding to changing circumstances, distributing loads efficiently across the enterprise and ensuring that performance goals are met.
• Reduce costs – eliminate the need for costly in-house development of automation tools.
• Eliminate islands of automation – Use a single enterprise job scheduler to manage jobs across all platforms, including applications.
• Single point of control – Get visibility into workload processing for the enterprise, and control the execution and management of dynamic workloads from one interface.
• Manage dynamic workloads – respond to real time enterprise events.
• Proactively meet service levels – respond to changing circumstances, and distribute loads efficiently across the enterprise to ensure that performance goals are met.

UC4 Benefits with our Data Automation solution

• Automates business intelligence and data warehousing processes, end to end.
• Helps quickly, efficiently, and accurate move data in, around, and outside of your data center.
• Simplifies the task of getting the right information to the right people at the right time.

And it also include:

• Quality of Service control: context-aware automation with event sensing, pattern mapping and policy-based management.
• Decision support: root cause analysis, workload analysis and reporting
• Job Scheduling: support for more than 19 operating systems and hypervisors
• Application Process Automation: rapid implementation with standardized process templates for leading ERP and industry applications
• Run Book: broad range of prepackaged functions for the most important data center operations
• Virtualization Management: capacity provisioning and integration to System Center and vCenter
• Application Release Automation: process flows, packaging, release and patch deployment
• Managed File Transfer: high-performance transfer from any platform with encryption, compression and check point restart.
