ORA-00020: maximum number of processes (n) exceeded in ASM Instance

Thu, 2011-08-04 08:02
Solution
---------

Increase the PROCESSES parameter in the ASM parameter file

Processes = 25 + 15 * n, where n is the number of instances on the box using ASM for their storage.

NOTE : this formula is for a basic instance and does not accomodate for

* Multiple ARCH processes
* Multiple LGWR processes

Should the ORA-0020 occur even after implementing this formula ... add additional for any multiples of these background processes


Refer NOTE 265633.1 "ASM Technical Best Practices" for more information.

20.42 SPACE HEADER

Cause
*******

One of the circumstances under which a 'SPACE HEADER' segment gets created is if a 'dictionary managed' tablespace is migrated to 'locally managed' (see dbms_space_admin.tablespace_migrate_to_local()).

The space header segment contains the extent bitmap and is allocated during the migration of the tablespace. Since there is no reserved space after the file header (as with locally managed tablespaces) the bitmap segment will be allocated somewhere in the "data" area of the datafile. During its creation the segment will pick up some of the storage attributes (e.g. MAXEXTENTS) from the default storage clause of the tablespace. Once the segment has been created it can neither be dropped nor changed.

Fix
****

You can ignore these "left-over" objects. Please go ahead and drop old tablespaces

How to Purge the RECYCLEBIN in Oracle 10g

Tue, 2008-03-25 21:49
THE RECYCLE BIN
*****************


The Recycle Bin is a virtual container where all dropped objects reside. Underneath the covers, the objects are occupying the same space as when they were created. If table EMP was created in the USERS tablespace, the dropped table EMP remains in the USERS tablespace. Dropped tables and any associated objects such as indexes, constraints, nested tables, and other dependant objects are not moved, they are simply renamed with a prefix of BIN$$. You can continue to access the data in a
dropped table or even use Flashback Query against it. Each user has the same rights and privileges on Recycle Bin objects before it was dropped. You can view your dropped tables by querying the new RECYCLEBIN view. Objects in the Recycle Bin will remain in the database until the owner of the dropped objects decides to permanently remove them using the new PURGE command. The Recycle Bin objects are counted against a user's quota. But Flashback Drop is a non-intrusive feature. Objects in the Recycle Bin will be automatically purged by the space reclamation process if

o A user creates a new table or adds data that causes their quota to be exceeded.
o The tablespace needs to extend its file size to accommodate create/insert operations.


There is no issues with DROPping the table, behaviour wise. It is the same as in 8i / 9i. The space is not released immediately and is accounted for within the same tablespace / schema after the drop.

When we drop a tablespace or a user there is NO recycling of the objects.

o Recyclebin does not work for SYS objects

We can also create a new table with the same name at this point.

@NOTE:
@Pre-10.1.0.3, the recycled objects can also be viewed in user_tables and dba_tables
@Fix for Bug 3255906 changed this behaviour to maintain compatibility with 9i



PURGING
********


In order to completely remove the table from the DB and to release the space the new PURGE command is used.

From BH user:
SQL> PURGE TABLE t1;
Table purged.

OR

SQL> PURGE TABLE "BIN$1UtrT/b1ScbgNAgAIKds8A==$0";
Table purged.

From SYSDBA user:
SQL> SELECT owner,original_name,operation,type
2 FROM dba_recyclebin
3 /
no rows selected

From BH user:
SQL> SHOW recyclebin
SQL>

There are various ways to PURGE objects:

PURGE TABLE t1;
PURGE INDEX ind1;
PURGE recyclebin; (Purge all objects in Recyclebin)
PURGE dba_recyclebin; (Purge all objects / only SYSDBA can)
PURGE TABLESPACE users; (Purge all objects of the tablespace)
PURGE TABLESPACE users USER bh; (Purge all objects of the tablspace belonging to BH)

For an object, the owner or a user with SYSDBA privilege or a user with DROP ANY... system privilege for the type of object to be purged can PURGE it.


DISABLING RECYCLEBIN
**********************


We can DROP and PURGE a table with a single command

From BH user:
SQL> DROP TABLE t1 PURGE;
Table dropped.

SQL> SELECT *
2 FROM recyclebin
3 /
no rows selected

There is no need to PURGE.

On 10gR1, in case we want to disable the behavior of recycling, there is an underscore parameter
"_recyclebin" which defaults to TRUE. We can disable recyclebin by setting it to FALSE.

From SYSDBA user:
SQL> SELECT a.ksppinm, b.ksppstvl, b.ksppstdf
FROM x$ksppi a, x$ksppcv b
WHERE a.indx = b.indx
AND a.ksppinm like '%recycle%'
ORDER BY a.ksppinm
/
Parameter Value Default?
---------------------------- ---------------------------------------- --------
_recyclebin TRUE TRUE

From BH user:
SQL> CREATE TABLE t1(a NUMBER);
Table created.

SQL> DROP TABLE t1;
Table dropped.

SQL> SELECT original_name
FROM user_recyclebin;
ORIGINAL_NAME
--------------
T1

From SYSDBA user:
SQL> ALTER SYSTEM SET "_recyclebin"=FALSE SCOPE = BOTH;
System altered.

SQL> SELECT a.ksppinm, b.ksppstvl, b.ksppstdf
FROM x$ksppi a, x$ksppcv b
WHERE a.indx = b.indx
AND a.ksppinm like '%recycle%'
ORDER BY a.ksppinm
/
Parameter Value Default?
---------------------------- ---------------------------------------- --------
_recyclebin FALSE TRUE

From BH user:
SQL> CREATE TABLE t1(a NUMBER);
Table created.

SQL> DROP TABLE t1;
Table dropped.

SQL> SELECT original_name
FROM user_recyclebin;
no rows selected

There is no need to PURGE.

As with anyother underscore parameter, setting this parameter is not recommended unless
advised by oracle support services.

On 10gR2 recyclebin is a initialization parameter and bydefault its ON.
We can disable recyclebin by using the following commands:

SQL> ALTER SESSION SET recyclebin = OFF;
SQL> ALTER SYSTEM SET recyclebin = OFF;

The dropped objects, when recyclebin was ON will remain in the recyclebin even if we set the recyclebin parameter to OFF.

Estimating the Network Band Width Required for Standby Database

Wed, 2008-01-30 00:15
For Better DR (Disaster Recovery) Site setup it is important to know the required Bandwidth Link Between the Primary and DR Site.

By using the Below formula, we can estimate the required Bandwidth Based on the Peak redo rate.

Required bandwidth = ((Redo rate in bytes per second / 0.7) * 8) / 1,000,000

= bandwidth in Mbps.

How to find a Redo Rate for a Database:-
*********************************************

Redo Rate can be found out from the Statspack report. During the peak duration of your business, run a Statspack snapshot at periodic intervals. For example, you may run it three times during your peak hours, each time for a five-minute duration. The Statspack snapshot report will include a "Redo size" line under the "Load Profile" section near the beginning of the report. This line includes the "Per Second" and "Per Transaction" measurements for the redo size in bytes during the snapshot interval. Make a note of the "Per Second" value. Take the highest "Redo size" "Per Second" value of these three snapshots, and that is your peak redo generation rate. For example, this highest "Per Second" value may be 394,253 bytes or 385 KB.

Req'd Bandwidth = ((394253 / 0.7) * 8) / 1,000,000
= 4.5 Mbps

How to Import the PUTTY Settings from One Machine to Another Machine

Mon, 2007-11-26 00:15
Most of the DBA's work 24 x 7 and finds difficiult and time consuming to configure the Whole List of Server settings in PUTTY. I had gone through Google hits and found one workaround to import your putty settings .


Work Around
************

1. Run the command --> regedit /e "%userprofile%\desktop\putty.reg" HKEY_CURRENT_USER\Software\SimonTatham at the command prompt.

2. Copy the Putty.exe and putty.reg onto Target Machine.

3. Right Click the putty.reg and click the option "Merge", this will import the settings to the target registry, and after that you can see all the server details which were defined by you earlier in Source Machine.

Note:- SimonTatham is the person behind the PUTTY Software.

Upgrading the Recovery Catalog Database from 9i to 10g

Mon, 2007-11-19 19:18
The Rman Catalog Upgarde is same as normal Database upgrade and can be accomplished in two ways.

a) Updrade the Database from 9i to 10g
- Connect to rman catalog datase.
- Issue the rman command "upgrade catalog" as this upgrades the catalog database from 09.02.00 to 10.02.00.03

b) Fresh Install of 10g Database / Use the existing 10g Database.
- Create the rman user and grant create session, recovery_catalog_owner, create type to rman user.
- Export import of Rman Schema
- Issue the rman Command :upgrade catalog"


Note:- You will encounter the below warning or error message , if you have not upgraded the catalog after the database version upgrade.
connected to target database: DSSPROD (DBID=1021024992)
connected to recovery catalog database
PL/SQL package RMAN.DBMS_RCVCAT version 09.02.00 in RCVCAT database is too old

Solution
**********
1. Connect to recovery catalog database as rman user.
2. issue the rman command " upgrade catalog" twice

Sizing the UNDO TABLESPACE for Automatic Undo management

Thu, 2007-11-15 21:43
Sizing an UNDO tablespace requires three pieces of data.

- (UR) UNDO_RETENTION in seconds
- (UPS) Number of undo data blocks generated per second
- (DBS) Overhead varies based on extent and file size (db_block_size)

UndoSpace = [UR * (UPS * DBS)] + (DBS * 24)

Two can be obtained from the initialization file: UNDO_RETENTION and DB_BLOCK_SIZE.
The third piece of the formula requires a query against the database. The number of undo blocks generated per second can be acquired from V$UNDOSTAT.


The following formula calculates the total number of blocks generated and divides it by the amount of time monitored, in seconds:

SQL>SELECT (SUM(undoblks))/ SUM ((end_time - begin_time) * 86400) FROM v$undostat;

Column END_TIME and BEGIN_TIME are DATE data types. When DATE data types are subtracted, the result is in days. To convert days to seconds, you multiply by 86400, the number of seconds in a day.

The result of the query returns the number of undo blocks per second. This value needs to be multiplied by the size of an undo block, which is the same size as the database block defined in DB_BLOCK_SIZE.


The following query calculates the number of bytes needed:

SQL> SELECT (UR * (UPS * DBS)) + (DBS * 24) AS "Bytes"
FROM (SELECT value AS UR FROM v$parameter WHERE name = 'undo_retention'),
(SELECT (SUM(undoblks)/SUM(((end_time - begin_time)*86400))) AS UPS FROM
v$undostat), (select block_size as DBS from dba_tablespaces where
tablespace_name= (select value from v$parameter where name
= 'undo_tablespace'));

Enabling , Disabling , Change the password protection on the RDBMS and Tools (8.0.6) listeners in an Oracle Applications 11.5.x

Run one of the following commands

Example 1: To enable listener password

addlnctl.pl contextfile=$CONTEXT_FILE enablepassword

Example 2: To disable listener password

addlnctl.pl contextfile=$CONTEXT_FILE disablepassword

Example 3: To change existing listener password

addlnctl.pl contextfile=$CONTEXT_FILE changepassword

Further information:
This will change the contextfile variable s_enable_listener_password to "ON" or "OFF"
Update/Remove the listener.ora with a PASSWORDS_PROD entry and the encypted password value

Example

PASSWORDS_PROD=BC73ED1DD01AC862
If the listener is not running it will not start it.
If the listener is currently running it will stop and restart it.
Controlling a password protected listener .Once the password is enabled the following methods can now be used to stop/start the listener:-


Apps Tier:

Use script $COMMON_TOP/admin/scripts/$CONTEXT_NAME/adalnctl.sh

Examples:-
$COMMON_TOP/admin/scripts/$CONTEXT_NAME/adalnctl.sh start
$COMMON_TOP/admin/scripts/$CONTEXT_NAME/adalnctl.sh stop

This script will check the listener.ora for the encypted password, and use this to stop/start the listener.

DB Tier:

Method A: Use script $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/addlnctl.sh

Examples:-

$ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/addlnctl.sh start PROD
$ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/addlnctl.sh stop PROD

This script will check the listener.ora for the encypted password, and use this to stop/start the listener.

Method B : Use command line options in the Listener Control Utility LSNRCTL
Start the Listener Control Utility

$ lsnrctl

Enter the listener name
LSNRCTL > set current_listener PROD

Enter password for the Listener
LSNRCTL > set password or

Examples:

LSNRCTL > set password 654FA907952B15B

or:

LSNRCTL > set password
Password: apps

To determine the Status of the listener:
LSNRCTL > status

To Stop the listener:
LSNRCTL > stop

To start the listener:
LSNRCTL > start

To exit :
LSNRCTL > start

Changing DB 32-Bit to 64-Bit

Tue, 2007-11-06 02:56
INSTALLING THE 64BIT RELEASE

1. Ensure that there is ample free size for the 64bit release installation.
Recommended free space should be 3G.

2. Start the Installer GUI.


3. On the File Locations Screen, create a new name and path for the 64bit
oracle installation under the Destination.

A typical entry would be

Name: orahome920_64b
Path: /u01/app/oracle/product/9.2.0-64b

4. Proceed with the installation. Stop at the configuration assistant
configuration screen.

5. Install the latest 64bit patch set under the new oracle installation.


CHANGING THE WORD-SIZE OF YOUR CURRENT RELEASE

The instructions in this section guide you through changing the word-size of
your current release (switching from 32-bit software to 64-bit software or vice versa).

Complete the following steps to change the word-size of your current release:

1. Start SQL*Plus.

2. Connect to the database instance AS SYSDBA.

3. Run SHUTDOWN IMMEDIATE on the database:
SQL> SHUTDOWN IMMEDIATE

4. Perform a full offline backup of the data depending on the available backup
mechanism, eg BCV, Unix file copy.

5. If the initialization parameter file eg initSID.ora, spfileSID.ora, listener.ora, sqlnet.ora resides within the old OR
ACLE_HOME, then copy it to the corresponding location of the new 64b it ORACLE_HOME. If the parameter files are symbol
ic links to another location, then the symbolic links have to be created in the new ORACLE_HOME.

Example:
Old $ORACLE_HOME/dbs
initSID.ora->/u01/app/oracle/admin/lss/initSID.ora
spfileSID.ora->/u01/app/oracle/admin/lss/spfileSID.ora
The same links have to be created in new $ORACLE_HOME/dbs.


6. Change your active Oracle instance environment to point at the new 64Bit ORACLE_HOME.
Eg
a)
Edit /var/opt/oracle/oratab if using dbhome/oraenv to set the environment.

lss:/u01/app/oracle/product/9.2.0:Y

i) set it to the new 64bit Oracle Home path

lss:/u01/app/oracle/product/9.2.0-64b:Y

b)
Change the essential environment setting eg $ORACLE_HOME,$LD_LIBRARY_PATH to use new 64bit Oracle Home Path if h
ardcoded

export ORACLE_HOME=/u01/app/oracle/product/9.2.0

Change to

export ORACLE_HOME=/u01/app/oracle/product/9.2.0-64b

7. Set AQ_TM_PROCESSES=0 if it is not.

a) If using initSID.ora to start instance, then add it to the init file.

b) If using spfileSID.ora to start instance,then the database can be startup and the parameter set by running th
e below command.

SQL> ALTER SYSTEM SET aq_tm_processes=0 SCOPE=SPFILE;

c) shutdown the database again.
9. Set _system_trig_enabled = false.

a) If using initSID.ora to start instance, then add it to the init file.
b) If using spfileSID.ora to start instance, then the database can be startup and the parameter set by running th
e below command.

SQL> ALTER SYSTEM SET "_system_trig_enabled"=FALSE SCOPE=SPFILE;

c) shutdown the database again.


The parameter should be set to FALSE for scripts that perform dictionary operations as the objects on which the triggers d
epend may become invalid or be dropped, causing the triggers to fail and thus preventing the scripts from running successf
ully.

10. When migrating from a 32-bit Oracle version to a 64-bit Oracle version, Oracle recommends doubling the size of paramet
ers such as:

SHARED_POOL_SIZE
SHARED_POOL_RESERVED_SIZE
LARGE_POOL_SIZE

11. At a system prompt, change to the new 64bit ORACLE_HOME/rdbms/admin
directory.

12. Start SQL*Plus.

13. Connect to the database instance AS SYSDBA.

14. Run STARTUP RESTRICT:

SQL> STARTUP RESTRICT

15. Run the following script:

SQL> @?/rdbms/admin/catalog.sql

16. Check for DBMS_PACKAGE validity.

17. If invalid, run below

SQL> alter package dbms_standard compile;
18. Run the following script:

SQL> @?/rdbms/admin/catproc.sql

19. Set the system to spool results to a log file for later verification of
success.

SQL> SPOOL /tmp/catoutw.log

20. Run utlirp.sql:

SQL> @?/rdbms/admin/utlirp.sql

The utlirp.sql script recompiles existing PL/SQL modules in the format required by the new database. This script first
alters certain dictionary tables. Then, it reloads package STANDARD and DBMS_STANDARD, which are necessary for using P
L/SQL. Finally, it triggers a recompile of all PL/SQL modules, such as packages, procedures, types, and so on.

21. Turn off the spooling of script results to the log file:

SQL> SPOOL OFF

Then, check the spool file and verify that the packages and procedures compiled successfully. You named the spool fil
e in Step 12; the suggested name was catoutw.log. Correct any problems you find in this file.


22. Run ALTER SYSTEM DISABLE RESTRICTED SESSION:

SQL> ALTER SYSTEM DISABLE RESTRICTED SESSION;

23. Remove the parameter aq_tm_processes or set value back to the original value.

a) If using initSID.ora to start instance, then remove or edit it from the init file after shutting down the data
base.

b) If using spfileSID.ora to start instance, then the parameter can be change by running the below command.

SQL> ALTER SYSTEM SET aq_tm_processes= SCOPE=SPFILE;

To remove the parameter.

SQL> ALTER SYSTEM RESET aq_tm_processes SCOPE=SPFILE SID=.*.;
24. Remove the parameter _system_trig_enabled = FALSE

a) If using initSID.ora to start instance, then remove it from the init file after shutting down the database.

b) If using spfileSID.ora to start instance, then the parameter can be removed by running the below command.

SQL> ALTER SYSTEM RESET "_system_trig_enabled" SCOPE=SPFILE SID=.*.;

25. The word-size of your database is changed. The database can be shutdown and reopen for normal use.

STEPS INVOLVED in PATCHING

STEPS Involved in patching
***************************

1. Install the Developer 6i Patch

2. Install the Additional Developer 6i Patches

3. Relink Applications Executables on UNIX Platforms


You can relink these executables by running adadmin
When the Main Menu appears select 'Maintain Applications Files Menu' and then select 'Relink Applications Program'
Answer the questions below as follows, in order to select the individual executables for relinking.

Enter list of products to link ('all' for all products)[all] : fnd
Generate specific executables for each selected product [No] ? y
Relink with debug information [No] ? n

(You will then be offered a list of executables that are available for relinking)

Enter executables to relink, or enter 'all' [all] : f60webmx ar60run ar60runb ar60rund *

* In a multi-node configuration, not all these executables exist on each node. The list of executables will show those that do exist on the node you are currently running on, and only those should be entered to avoid errors.

Refer to the Maintaining Oracle Applications manual for more information on how to use the AD Administration Utility or AD Relink Utility for relinking executables.


4. Apply the Oracle Applications 11i Interoperability Patch


5. Verify your upgrade

Verify that the fndforms.jar and fndewt.jar JAR files have been rebuilt by checking the timestamp for both files in the $OA_JAVA/oracle/apps/fnd/jar directory. If the timestamp is not current and the previous steps completed successfully, run the AD Administration Utility (adadmin), select Maintain Applications Files, then select Generate Product JAR Files. Do not force the regeneration of all JAR files. Again, verify that the fndforms.jar and fndewt.jar JAR files have been rebuilt by checking their timestamps again.
If your JAR files are still not updated, verify all the prior steps, and the Known Issues section below.
If you have applied Developer 6i Patch 6 or above, verify that the PL/SQL version installed is 8.0.6.3.x. You can run '$ORACLE_HOME/bin/f60gen help=y' to display various component versions. (If the version shown is still 8.0.6.0.x please refer to Metalink Note 191573.1 )
For Microsoft Windows platforms, look under Control Panel - Services to see if additional Forms and Reports services were added. If so, disable the new ones by pressing the Startup button, and setting the Startup Type toDisabled.


6. Start the Forms, Reports, HTTP, Concurrent Manager Servers

a. Stop the Forms Server process.

b. Add the following environment variable to the 'Oracle Forms 6.0 environment variables' section of
your '$APPL_TOP/< SID >.env' file as;

FORMS60_RESTRICT_ENTER_QUERY="TRUE"
export FORMS60_RESTRICT_ENTER_QUERY

c. Source the environment, then restart the Forms Server process
