1. CHECK WHETHER THE INSTANCES RMANCAT,DONSDMP,DONSRCP IS UP OR NOT.

ANS: APDWD506:NONE:[/USR/APP/ORACLE]> ps –aef | grep pmon

ORACLE 848028 1 0 JUN 11 - 0:24 ORA_PMON_DONSDMP ORACLE 954504 1 0 JUN 11 - 0:24 ORA_PMON_RMANCAT ORACLE 1085656 1 0 19:01:28 - 0:03 ORA_PMON_DONSRCP ORACLE 1200218 1249384 0 01:40:51 PTS/8 0:00 GREP PMON

ORA_PMON_DONSDMP, ORA_PMON_RMANCAT, ORA_PMON_DONSRCP shows that all these instances are up.

2. CHECK WHETHER THE DATABASE RMANCAT IS UP OR NOT.

ANS:

sql> select instance_name, status from v$instance;

INSTANCE_NAME STATUS------------------------------------------RMANCAT OPEN

(OR)

sql> select open_mode from v$database;

OPEN_MODE ---------- READ WRITE

Read write mode specifies RMANCAT is UP

3. IDENTIFY THE LOCATION OF PFILE,SPFILE,CONTROLFILE,LOG MEMBER FOR RMANCAT.ANS:

(A)

$ find / -name initRMANCAT.ora.

apdwd506:RMANCAT:[/usr/app/oracle/product/10.2.0/dbs]> ls

afiedt.buf lkDONSRCPalert_DONSRCP.log lkRMANCATcd lshc_DONSDMP.dat orapwDONSDMPhc_DONSRCP.dat orapwDONSRCPhc_RMANCAT.dat orapwDONSRCP.bkpinit.ora orapwRMANCATinitDONSDMP.ora orapwsidinitDONSDMP2.ora snapcf_DONSDMP.finitDONSRCP.ora snapcf_DONSRCP.finitDONSRCP.ora_bkpaug8 spfileDONSDMP.orainitRMANCAT.ora spfileDONSDMP.ora.oldinit_DONSDMP_jul29_bkp.ora spfileDONSRCP.ora.oldinitdw.ora spfileRMANCAT.oralkDONSDMP sqlnet.log

Here default location of pfile is initRMANCAT.ora

The alertlog can give the non default location of pfile and spfile.

(B)

This can be displayed only when database is running on spfile.

4. IDENTIFY WHETHER THE DATABASE RMANCAT IS SETUP IN ARCHIVE LOG MODE.

ANS:

sql> select log_mode from v$database;

LOG_MODE---------------------NOARCHIVELOG

(OR)

sql> archive log list

DATABASE LOG MODE NO ARCHIVE MODEAUTOMATIC ARCHIVAL DISABLEDARCHIVE DESTINATION /USR/APP/ORACLE/PRODUCT/10.2.0/DBS/ARCHOLDEST ONLINE LOG SEQUENCE 41CURRENT LOG SEQUENCE 43

(OR)

NOTE:

Sql> select archiver from v$instance;

Archiver column has only one value i.e FAILED irrespective of the database in Archive or Noarchivelog mode. Hence this query can not be used to fetch required information.

5. IDENTIFY SIZE OF THE SGA AND FIND WHETHER THE AUTO MEMORY TUNING IS ENABLED.ANS:

(A) Sql> select * from v$sga;

(B)

Sql> sho parameter sga;

NAME TYPE VALUE------------------------------------ ----------- ------------------------------LOCK_SGA BOOLEAN FALSEPRE_PAGE_SGA BOOLEAN FALSESGA_MAX_SIZE BIG INTEGER 124MSGA_TARGET BIG INTEGER 0

Since the SGA_TARGET value is zero, so AUTO MEMORY TUNING is not enabled.

DESCRIPTION

NUM NUMBER Parameter number

NAME VARCHAR2(80) Name of the parameter

TYPE NUMBER Parameter type: 1 - Boolean2 - String3 - Integer4 - Parameter file5 - Reserved6 - 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 SESSIONSYSTEM_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

It is not possible to drop a logfile group that is either current or active. (Current: it is the logfile group in use at the moment; Active: The contents of the logfile group are being written/have not yet been written into the archive logs. It takes time for the redo logs to be written in the archive logs. Take down the log sequence number of the redo log and check if that has been written into the archived logs by the v$archived_log view. If the sequence number exists in the v$archived_log view, the redo log group can be dropped successfully.

2. TAKE AN IMAGE COPY OF TABLESPACE "TBS01" USING THE FORMAT KEYWORD SPECIFYING THE LOCATION OF THE BACKUP AS '....../RMANCAT1/COPY/.......'

The following command works when the tablespace has one or more datafiles. However, if we try to specify a separate name to the copy when the tablespace has more than datafile, the copy will fail as it tries to assign the same name to the copy of each datafile, thus throwing an error.This error is shown in one of the examples below highlighted in red.

5. WRITE A RMAN SCRIPT USING RUN BLOCK USING THE FOLLOWING CONDITIONS

A)NUMBER OF CHANNELS USED SHOULD BE 3B)BACKUPS FULL DATABASE(INCREMENTAL LEVEL 0) WITH ALL THE ARCHIVE LOGSC)MAXIMUM SIZE OF A BACKUPSET SHOULD NOT EXCEED

100MD)EACH BACKUPSET SHOULD CONTAIN ONLY ONE BACKUP

PIECEE)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.
