To grant privileges on one user objects to another user
You could write a simple loop :
begin
for i in
(select distinct table_name from all_tables where owner='USER_A')
loop
execute immediate 'grant all on '||i.table_name||' to USER_B';
end loop;
end;
/

To find users who have DBA role means List of Persons Having DML Access
Select username, created from dba_users where username in (Select grantee from dba_role_privs where granted_role = 'DBA');


To find temporary tablespace usage query
"SELECT s.sid ""SID"",s.username ""User"",s.program ""Program"", u.tablespace ""Tablespace"",
u.contents ""Contents"", u.extents ""Extents"", u.blocks*8/1024 ""Used Space in MB"", q.sql_text ""SQL TEXT"",

WHERE s.saddr=u.session_addr
and s.sql_address=q.address
and s.sid=a.sid
and u.tablespace=k.tablespace_name;


How would you check if the tablespace is in backup mode ?- Check in v$backup
SQL> SELECT d.tablespace_name, b.status FROM dba_data_files d, v$backup b
WHERE d.file_id = b.FILE# and b.STATUS = ‘ACTIVE’ ;


how to monitor dba_jobs of materialized view

To force a logfile switch use

ALTER SYSTEM SWITCH LOGFILE;

Put db in archive mod in 10g
If your DB is in no Archive log mode then change the mode to Archive log.

Set FRA (Flash Recovery Area) in your init/spfile.ora

DB_RECOVERY_FILE_DEST=/u03/FRA
DB_RECOVERY_FILE_DEST_SIZE=4G

Startup up the database in mount state

$ sqlplus / as sysdba

SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVE LOG;
SQL> ALTER DATABASE OPEN;
SQL> ARCHIVE LOG LIST;

To force a checkpoint use

ALTER SYSTEM CHECKPOINT;


In Oracle 10.1 and above, the following supported command can be used to flush the buffer cache:

ALTER SYSTEM FLUSH BUFFER_CACHE;
In Oracle 9.0.1 and above the following unsupported command can also be used to flush the buffer cache:

ALTER SESSION SET EVENTS 'immediate trace name flush_cache';
After this command has been executed, the STATE column for all rows in X$BH will be zero unless the block is currently pinned

To flush the shared pool use:

ALTER SYSTEM FLUSH SHARED_POOL;

move all objects from tools to apps_ts_tools and then drop tools tablepsaceEg:
alter TABLE USIDBA.USI_ALERT_LOG move tablespace APPS_TS_TOOLS
alter index USIDBA.USII0_INFO rebuild online tablespace APPS_TS_TOOLS parallel 2;

To check on which directories you have privilege to read & write:
#################################################################

SQL> SELECT privilege, directory_name
2 FROM user_tab_privs t, all_directories d
3 WHERE t.table_name(+)=d.directory_name
4 ORDER BY 2,1;

Re-creating Dba_directories
drop directory COST_DIR;
create directory COST_DIR as '/d01/oravis/visappl/xxhem/11.5.0/datain/Cost';

grant all on directory COST_DIR to apps;

Using ANALYZE command is little bit older now. If you are using oracle >8i then you have new package called dbms_stats.
To analyze schema use
dbsm_stats.gather_schema_stats 'USERNAME',casacde=>true,estimate_percent=>10);
For table use the following
dbms_stats.gather_table_stats

syntax for analysing a table is :
ANALYZE TABLE emp ESTIMATE STATISTICS;
The full syntax (not using DBMS package) is

ANALYZE TABLE xxxxx ESTIMATE STATISTICS SAMPLE 20 PERCENT;
analyze table Dec6Table4 compute statistics;
Oracle will actually read through all the blocks/rows to compute the true value of the stats"

To drop and re-create the statistics on sys schema
SQL> EXECUTE DBMS_STATS.DELETE_SCHEMA_STATS('SYS');
SQL> EXECUTE DBMS_STATS.GATHER_SCHEMA_STATS('SYS');


exec fnd_stats.gather_schema_statistics('SYS');
exec fnd_stats.gather_schema_statistics('SYSTEM');
exec fnd_stats.gather_schema_statistics('ONT');

sqlplus apps/
SQL> exec fnd_stats.gather_schema_statistics('MRP'); <- One schema
SQL> exec fnd_stats.gather_schema_statistics('ALL'); <- All schemas
SQL> exec fnd_stats.gather_table_stats('MRP','MRP_FORECAST_DATES'); <- One table
exec fnd_stats.gather_schema_statistics(SCHEMANAME =>'XXBR',ESTIMATE_PERCENT=>10,HMODE=>'LASTRUN',OPTIONS=>'GATHER AUTO',MODPERCENT=>5,INVALIDATE=>'Y');


To find out a hidden parameter value in the database
SELECT a.ksppinm ""Parameter"",
b.ksppstvl ""Session Value"",
c.ksppstvl ""Instance Value""
FROM x$ksppi a, x$ksppcv b, x$ksppsv c
WHERE a.indx = b.indx AND
a.indx = c.indx AND
a.ksppinm LIKE '%kgl_large_heap%';

To get a list of all deprecated initialization parameters, issue the following SQL statement:
SELECT name FROM v$parameter WHERE isdeprecated = 'TRUE';


How to Inovke SQLPLUS in scripts in Oracle 10g !!!
In Oracle 9i we use ""sqlplus -s @start_mydb.sql"" to start the database. But, where as in Oracle 10g this command simply hangs and will not do anything.

To invoke SQLPLUS in shell/bat scripts in Oracle 10g, We need to give below command.
sqlplus /NOLOG @start_mydb.sql


How to find the ORACLE_HOME path in Oracle Database?
In 9i:

SELECT substr(file_spec,1,instr(file_spec,'lib')-2) ORACLE_HOME FROM dba_libraries
WHERE library_name='DBMS_SUMADV_LIB';

In 10g:

SQL > var OHM varchar2(100);
SQL > EXEC dbms_system.get_env('ORACLE_HOME', :OHM) ;
SQL > PRINT OHM

Linux/Unix:

echo $ORACLE_HOME

Windows:

start - run - regedit (enter) - HKEY_LOCAL_MACHINE - SOFTWARE - ORACLE

Type the below command at prompt if the environment variable is defined for ORACLE_HOME

c:\> set oracle_home (ENTER)


Using ORA_ROWSCN and SCN_TO_TIMESTAMP to find the last updated date or timestamp of a record.
SQL> SELECT scn_to_timestamp(ORA_ROWSCN) FROM emp WHERE empno=7839;

SCN_TO_TIMESTAMP(ORA_ROWSCN)
------------------------------------
02-SEP-08 03.20.20.000000000 PM"


To find database characterset
SQL> SELECT * FROM nls_database_parameters;
SQL> select * from nls_database_parameters
2 where parameter in ('NLS_LANGUAGE','NLS_TERRITORY','NLS_CHARACTERSET');

PARAMETER VALUE
------------------------------ ----------------------------
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CHARACTERSET WE8ISO8859P1
"
"Set the NLS_LANG environment variable according the database character set and language details.
$ export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1

Following script can be used to construct the dblink.
SELECT‘create ‘||DECODE(U.NAME,’PUBLIC’,'public ‘)||’database link ‘||CHR(10)||DECODE(U.NAME,’PUBLIC’,Null, U.NAME||’.')|| L.NAME||chr(10)    ||’connect to ‘ || L.USERID || ‘ identified by ”’||L.PASSWORD||”’ using ”’ || L.host || ””   ||chr(10)||’;’ TEXTFROM  sys.link$       L,      sys.user$       UWHERE L.OWNER# = U.USER# ; 

To drop db links
SQL> select 'drop database link '||b.username||'.'||c.name||' ;'
from dba_users b ,link$ c
where c.owner#=b.user_id
union
select 'drop public database link '||c.name||' ;'
from link$ c
where owner#=1;
To test DB links
select * from dual@link name; need to put tns entries for using colomun

To find/create DB links
select 'DB link for '||b.username||chr(10)||' create database link '||c.name||' connect to '||c.userid|| ' identified by '||c.password||' using '''||c.host||''';'
from dba_users b ,link$ c
where c.owner#=b.user_id
union
select 'DB link for Public' ||chr(10)|| ' create public database link '||c.name||' connect to
'||c.userid|| ' identified by '||c.password||' using '''||c.host||''';'
from link$ c
where owner#=1
;

select owner||','||DB_LINK||','||USERNAME||','||HOST||','||created from dba_db_links;

To create db link b/w two instances:
VIS is the non-prod ASCP instance. All ASCP related db links should point to VIS.

Login to the DB as system user:
Drop public database link PLAN;
Drop public database link VIS;
Create public database link PLAN connect to APPS identified by APPS using ‘VIS’;
Create public database link VIS connect to APPS identified by APPS using ‘VIS’;

Login to the DB as apps user:
Drop database link PLAN;
Drop database link VIS;
Create database link PLAN connect to APPS identified by APPS using ‘VIS’;
Create database link VIS connect to APPS identified by APPS using ‘VIS’;

To revert the password back
SQL> alter user abc identified by values '901D29B9D7CACF3D';

To know the value of any parameter listed in init.ora.
select name , value from v$parameter; or
show parameter dump;

To know database status
select status from v$instance;

To know database name
select name from v$database


Enabling hot backup
1.do the following changes in init file:

log_archive_start = true
log_archive_format = SID_%t_%s.arc (SID - instance name)
log_archive_dest = '/ux1/oraarch/SID’ REOPEN' (x - could be 1,2,3 etc; there's a space after SID)

2.shutdown immediate;
3.startup mount;
4.alter database archivelog;
5.alter database open ;
6.archive log list; (to check the changes are there)
7.alter system switch logfile;
8.check the log dir.Verify that log files are getting written there or not.

To take the DB out of archive mode
SQL>sqlplus "" / as sysdba""
SQL>archive log stop;
SQL>alter database noarchivelog;
4. Shutdown the database.
5. Start the database instance
sqlplus "" / as sysdba""
SQL>startup pfile=/d01/vis/sw/920/dbs/initvis.ora -- This init.ora file has been updated to start the database in noarchivelog mode
SQL>archive log list; -- This should show that automatic archival is disabled and that the database is running in noarchivelog mode"


If Compiling Invalids manually:
i) As sysdba run utlrcmp.sql from rdbms/admin
Then as sysdba run the follwoing
exec utl_recomp.recomp_parallel (8);(8 – no. Of workers)
ii) in case of Materialized Views:
TO COMPILE INVALID OBJECTS WE CAN USE THE FOLLOWING SYNTAX exec
dbms_mview.refresh ('VIEW NAME');

Syntax to refresh meterilaized view:

SQL> connect apps/xxx
Connected.
SQL> begin
2 dbms_snapshot.refresh('CCOR_NETRV_MV','c');
3 end;
4 /

dbms_refresh.refresh('"APPS"."FREIGHT_NOT_INVOICED_MV"');

INVALIDS IN SPECIFIC FORMAT
Invalid objects listing by name, type, owner; total count.
spool original_invalids.lst
col owner format a15
col object_name format a35
col object_type format a18
select count(*) from dba_objects where status = 'INVALID';
select object_name, object_type, owner from dba_objects where status = 'INVALID';
spool off;

Invalid objects listing by name, type, owner; total count.
spool original_invalids.lst
col owner format a15
col object_name format a35
col object_type format a18
select count(*) from dba_objects where status = 'INVALID';
select owner, object_name, object_type from dba_objects where status = 'INVALID' order by owner, object_name;
spool off;

Number of database objects by owner, type (order by owner, type). spool original_objects.lst
col owner format a15
col object_name format a35
col object_type format a18
select owner, object_type, count(object_type) from dba_objects group by owner, object_type order by owner, object_type;
spool off;"

select count(*) from dba_objects where status='INVALID';

SELECT owner, object_type, object_name
FROM dba_objects
WHERE status = 'INVALID'
AND object_name IN (SELECT referenced_name
FROM dba_dependencies
WHERE name ='WK_SNAPSHOT');

DBVERIFY for chechking database block corruption
dbv file=/u01/oradata/PROJDEV/invd02.dbf blocksize=8192 logfile=invd02_feb25.log feedback=10000

create a password file as follows:
$orapwd file=$ORACLE_HOME/dbs/orapwDB01
password=orapass(must be sys pwd) entries=5

set REMOTE_LOGIN_PASSWORDFILE to EXCLUSIVE.


to grant all privileges for all tables of a schema to another schema:
SQL> begin
for i in (select distinct table_name from all_tables where owner='MIM')
loop
execute immediate 'grant all on '||i.table_name||' to apps';
end loop;
end;
/


When starting listener for DB, you will find it asks for password.
Do the following :

lsnrctl
LSNRCTL>set current_listener PROD
LSNRCTL>set password

supply the pwd

LSNRCTL>stop or start as the case may be
LSNRCTL>exit
