MORE THAN 100 REAL TIME SCENARIOS WITH SOLVED ANSWERS
A HANDBOOK FOR DBAS
Published by ORACLE DBA TRAINEES TEAM
VERSION 1.0 NOV 2009
FOREWORD This handbook contains some real time scenarios Oracle DBAs face in their daily work. All questions in the book are fully solved. The book intends to provide a quick reference to various queries and views which would be useful in the daily work of a DBA.
ACKNOWLEDGEMENTS We would like to express our sincere gratitude to all who have helped us in bringing up this handbook. Firstly, we would like to thank the AMEX-IM/CDM team for their valuable support and encouragement. We would like to thank Mr.Anup Krishnan, Portfolio Director, IM-CDM Team, Mr.Padmanabha Reddy, Mr Ramesh.M, Mr.Dipak Laha, Mr.Vijay Venkatesh and Mr.Suresh Karthik. And last but not the least, a wholehearted thanks to our mentor, Mr.Magudapathi.S, who with his constant support and guidance drove this initiative into a success.

DESCRIPTION NUM
NUMBER
Parameter number
NAME
VARCHAR2(80)
Name of the parameter
TYPE
NUMBER
Parameter type: 1 - Boolean 2 - String 3 - Integer 4 - Parameter file 5 - Reserved 6 - Big integer
VALUE
VARCHAR2(512) Parameter value for the session (if modified within the session); otherwise, the instance-wide parameter value
DISPLAY_VALUE
VARCHAR2(512) Parameter value in a user-friendly format. For example, if the VALUE column shows the value 262144 for a big integer parameter, then the DISPLAY_VALUE column will show the value 256K.
ISDEFAULT
VARCHAR2(9)
Indicates whether the parameter is set to the default value (TRUE) or the parameter value was specified in the parameter file (FALSE)
ISSES_MODIFIABLE
VARCHAR2(5)
Indicates whether the parameter can be changed with ALTER SESSION (TRUE) or not (FALSE)
ISSYS_MODIFIABLE
VARCHAR2(9)
Indicates whether the parameter can be changed with ALTER SYSTEM and when the change takes effect: IMMEDIATE - Parameter can be changed with ALTER SYSTEM regardless of the type of parameter file used to start the instance. The change takes effect immediately. DEFERRED - Parameter can be changed with ALTER SYSTEM regardless of the type of parameter file used to start the instance. The change takes effect in subsequent sessions. FALSE - Parameter cannot be changed with ALTER SYSTEM unless a server parameter file was used to start the instance. The change takes effect in subsequent instances.
ISINSTANCE_MODIFIABLE VARCHAR2(5)
For parameters that can be changed with ALTER SYSTEm, indicates whether the value of the parameter can be different for every instance (TRUE) or whether the parameter must have the same value for all Real Application Clusters instances (FALSE). If the ISSYS_MODIFIABLE column is FALSE, then this column is always FALSE.
ISMODIFIED
VARCHAR2(10)
Indicates whether the parameter has been modified after instance startup: MODIFIED - Parameter has been modified with ALTER SESSION SYSTEM_MOD - Parameter has been modified with ALTER SYSTEM (which causes all the currently logged in sessions' values to be modified) FALSE - Parameter has not been modified after instance startup
ISADJUSTED
VARCHAR2(5)
Indicates whether Oracle adjusted the input value to a more suitable value (for example, the parameter value should be prime, but the user input a non-prime number, so Oracle adjusted the value to the next prime number)
ISDEPRECATED
VARCHAR2(5)
Indicates whether the parameter has been deprecated (TRUE) or not (FALSE)
DESCRIPTION
VARCHAR2(255) Description of the parameter
UPDATE_COMMENT
VARCHAR2(255) Comments associated with the most recent update
HASH
NUMBER
Hash value for the parameter name

WRITE A RMAN SCRIPT USING RUN BLOCK USING THE FOLLOWING CONDITIONS A)NUMBER OF CHANNELS USED SHOULD BE 3 B)BACKUPS FULL DATABASE(INCREMENTAL LEVEL 0) WITH ALL THE ARCHIVE LOGS C)MAXIMUM SIZE OF A BACKUPSET SHOULD NOT EXCEED 100M D)EACH BACKUPSET SHOULD CONTAIN ONLY ONE BACKUP PIECE E)BACKUP SHOULD NOT TAKE LESS THAN 10 MINUTES. F)SKIP THE "USERS01" DATAFILE // THISIS NOT POSSIBLE. FINALLY RUN THE ABOVE CREATED RUN BLOCK. The command below allocates 3 channels of device type. The backup type is an incremental level 0 i.e. a complete database backup. The duration of the backup is 10 minutes or less. There is one backup piece per backupset. The inaccessible tablespaces are skipped. It is not possible to skip a specified tablespace. We have specified “skip inaccessible” to skip those tablespaces which are invalid. The maximum size of a backupset should be at least the size of the biggest datafile. Here system is 500m in size. Thus it is not possible to keep maximum size of a backupset 100m.
