129) How
to Restore the Controlfile from Backup. If you loss or if your all copies of
control file is corrupted and if you have backup of your control file then it
is required to restore your control file from your backup
130) New Feature of
10.2g: Eliminate Control File Re-Creation. Before Oracle 10.2g
if we need to change the limit of MAXLOGFILE, MAXLOGMEMBERS, MAXLOGHISTORY,
MAXDATAFILES, and MAXINSTANCES then the possible solutions is either RE-create
new controlfile or create a new database. But from Oracle 10.2g all sections of
the control file are now automatically extended when they run out of space.
This means that there is no longer a requirement to re-create the control file
when changes in the configuration parameter the MAXLOGFILE, MAXLOGMEMBERS,
MAXLOGHISTORY, MAXDATAFILES, and MAXINSTANCES are needed
131) kccrsz: denied expansion
of controlfile section 9 by 65535 record(s). The machine did not
respond properly and in the alert log you the got the following. kccrsz: denied
expansion of controlfile section 9 by 65535 record(s) the number of records is
already at maximum value (65535).

then it fails with message ORA-00604: error occurred at recursive SQL level 1
along with ORA-01450: maximum key length (3215) exceeded.
133) How to determine OS
block size for windows or unix. In many times you probably
have heard about set the oracle db block size as a multiple of the OS block
size. But whenever you ask how I can determine or find OS block size for
windows or Unix then many one get stopped. In fact this question is OS related.
135) Playing with Oracle
data block size. I have experiment of oracle data block size
with 8k and 16K. I performed DML operation against both 8k and 16k data block
size. I created two tables table_8k under 8k tablespace tbs_8k and table_16k
under 16k tablespace tbs_16k. The summary of the experiment is bigger data
block cause more time while update but less time while insert operation.
138) DB_BLOCK_SIZE,
DB_nK_CACHE_SIZE and BLOCKSIZE. First I want to say about
BLOCKSIZE cluase in oracle. The BLOCKSIZE cluase is used to specify the block
size for the tablespace. If you don't specify this clause while tablespace
creation then standard that is default blocksize is used which is specified by
parameter DB_BLOCK_SIZE.
139) When datafile bytes
size greater than maxbytes. From dba_data_files we can check the
size of the datafile, the maximum size of the datafile it can grows if
AUTOEXTENSIBLE option is set and their status with many other fields.
141) ORA-01295: DB_ID
mismatch between dictionary USE_ONLINE_CATALOG and logfiles.

procedure fails with ORA-01295. May be you want to analysis redo log files of
the production database in the testing environment.
147) Archiving not
possible: No primary destinations. Today I got a very
interesting problem. The developer told me that they can't connect to database.
It says ORA-00257: archiver error. Then I log on to the database and it was ok.
I asked developer it is fine. After some time developers again asked me they
are having the same problem. I then look for alert log and saw the following
stack of message.
149) Table, View,

a significant amount of time to create repository and after analysis I got the
following
195) Running EMCA Fails
To Accept the DBSNMP Password. Today when I tried to
create DB Control on my computer I got an interesting problem.
199) Java.lang.Exception:
IOException in sending Request. this problem will appear
if you just change the Time Zone of your system.
200) You must have CREATE
TARGET privilege to perform this operation. In the Enterprise
Manager main page (connected with SYS as SYSDBA or as SYSTEM), when I click on
performance tab, it gives me following notification
202) In EM connection

Whenever you try to connect to enterprise manager after giving host username and password as prompted it fails with message
HostPassword - Connection to host as user oracle failed: ERROR: NMO not setuid-root (Unix-only)
204) Does oversize of
datatype VARCHAR2 causes performance problem. From the beginning
of learning Oracle SQL you have possibly heard that in case of VARCHAR2
datatype it allocates space exactly what it needs. So if you allocates 4000
bytes of VARCHAR2 data type and database needs 10 bytes only then exactly 10
bytes are allocated
219) Export fails with
ORA-24324 ORA-07445: exception encountered: core dump [ACCESS_VIOLATION].
Database export operation fails with ORA-24324 and ORA-07445
231) DataPump Export

235) Version Query
Pseudocolumns, The version query pseudocolumns are only
valid for flashback version query which are discussed on Flashback Version
Query.
236) ORA-01466: unable to
read data - table definition has changed, Whenever you tried to
flashback of a table immediately after creating table and inserting data into
it, or you tried to flashback of the table to a time or to a SCN before
creating it then flashback table or flashback query fails with error message,
237) ORA-08189: cannot
flashback row movement is not enabled, Whenever I tried to
Flashback Table feature of oracle the following error occurs.
239) Flashback ON fails
with ORA-38706 and ORA-38714, Whenever you tried to
enable your database flashback feature it failed with errors.
240) How
to get back dropped Tablespace using Flashback Database, It needs to remember
that if you drop your tablespace with including datafiles option then it is not
possible to get your tablespace back with flashback database. While dropping if
you use DROP TABLESPACE INCLUDING CONTENTS option then it is possible to get
back tablespace.
241) How to restore the
old data using flashback query, My intention is , I want
to get back past data of database after erroneously updated and committed.
242) Limitation
of Flashback Database, The Flashback Database allows you to get back the entire
database to a specific point-in-time
243) Flashback Database
To The Right of Open Resetlogs, In some cases, you may
need to return the database to a point in time in the parent incarnation, later
than the SCN of the OPEN RESETLOGS at which the current incarnation path
branched from the old incarnation.
244) Flashback Database
to Undo an OPEN RESETLOGS, Suppose you have opened your database
with OPEN RESETLOGS option after performing flashback feature. And after that
you have made unwanted changes in your database.
245) Performing Flashback
Database, Before going any production upgrade to database we can
make a guaranteed restore point to database and if any wrong then we can get
back to the restore point state. Guaranteed restore point always ensure that we
can get back data to our restore point creation time.
246) ORA-00439: feature
not enabled: Flashback Database, While trying to enable
flashback feature the error comes.
247) Restore Point and
Flashback Database. Flashback database enables us to get back
our database to a prior time
248) How to Enable
Flashback Database, To enable flashback database the following
operations is needed
249) Flashback Table and
Flashback Drop, The FLASHBACK TABLE statement enables users
to get a table to a previous point in time. It provides a fast, online solution
to get back a table that has been accidentally modified or deleted by a user or
application. It eliminates the DBA to perform more complicated point in time
recovery operations.

265) How to Import data
without Dumpfile-Network Mode Import, It is possible to import
data in a database without the dump file. From network the data will be
retrieved from one database and then import that data back to the target
database. There are no dump files involved.
266) Import
Oracle Data from Anywhere, Suppose, I have server machine named
"NEPTUNE". In the server machine under /oradata2 directory there is a
dump file named net.dmp. However to run import operation we need not connect to
server "NEPTUNE" and then perform import operation. From any machine
which have data pump import client can do the operation.

309) How to disable
SELinux, Before going to directly disabling SELinux let's have
an idea about what SELinux is. SELinux indicates Security Enhanced Linux which
is a security patch applied to Linux kernel. When it is enabled in the kernel
it follows some principle of least privilege. It is an implementation of
mandatory access control using Linux Security Modules.
312) While startup
listener it fails with HPUX Error: 29: Illegal seek,
While issuing "lsnrctl start" command on HP-UX it fails with HPUX
Error: 29: Illegal seek error like below
313) TNS-01169: The
listener has not recognized the password, The TNS-01169 error
occurred because security feature is enabled for listener i.e password is set
in listener.ora file but lsnrctl command is issued without proper
authentication
316) The listener
supports no services, Whenever I issue lsnrctl status command it
says "The listener supports no services" and no one from outside
could not connect to database through listener
317) Listener Hangs,
Child listener process remains persistence, Some days ago in
our database server we got a problem regarding listener issue. Our TNS Listener
hangs. Below is the problem symtompts.
318) ORA-12541: TNS:no
listener, For newbie users they found ORA-12541 and search here
and there to solve the problem. But it is one word about the error which it
says no listener and think next what to do. Never mix this error with another
error like ORA-12514: which are different and mutually exclusive.
319) ORA-12514:
TNS:listener does not currently know of service requested in connect descriptor, I
will try to show how efficiently we can avoid error ORA-12514. My suggestion is
whenever you get this error forget about tnsnames.ora and other stuff related
to it. Start fixing problem step by step.
320) How
to Enable Listener Logging and Tracing, I will try to show two different ways
to enable logging and tracing of listener.ora file. These logging and tracing
helps you to identify the network problems and troubleshooting connection
problems in oracle.It also help to identify when a client is connected to
oracle database.
321) RMAN login fails

331) Types
of Operators in Orace? Concatenation, Arthimetic, User-Defined, Hierarchial,
Set Operators?
335) Database Objects in
Oracle, If we look for database objects in oracle then there
comes two types of objects, one is schema objects that are associated with a
particular schema or in other word they are owned by a database user. And the
other is nonschema Objects that are not reside in a particular schema
336) How to Rename a User
Through Oracle, There is nothing straight forward command
in oracle to rename a user. You have to do it through several steps. In
following I have shown it.
337) Required users and
groups while installing oracle, Drop Table Command,
Default Tablespace in Oracle
339) Working an object
that resides on multiple datafile, An object can span in
multiple datafiles within a single tablespace. In this case if I make one
datafile offline then the contents within that datafile will be affected, other
datafile is online and can be possible to query which may return rows with
errors. To illustarte this scenario I will make two datafiles inside a
tablespace.

396) Troubleshoot
ORA-06512: at line, ORA-06512 is a common error faced by Oracle
DBA, programmers as well as end users. ORA-06512 does not identify the root
cause of the problem, rather it only prints the line number where the errors or
exception happened. So just before ORA-06512 there will be additional error
which we may need to investigate. If the errors come from any function or
package or package body or procedure then with ORA-06512 there exists the name
of the function or package or package body or procedure as well as the line
number of those objects where error is occurred.
