Regarding initialization parameters
Hai all,
Can anybody please help me regarding this initialization parameters like
1.what is correct value (how to find)
2. indetail about each parameter
1._optimizer_mjc_enabled
2.max_dump_file_size
3.optimizer_index_caching
4.optimizer_index_cost_adj
5.parallel_execution_message_size
6.parallel_max_servers
7.parallel_threads_per_cpu
8.processes
9.sessions
10.shared_pool_reserved_size
Following link would be the best place to get the details about all initialization parameters.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_2013.htm#i2154767
As regards to the best value, most of them would be your database specific. Start from oracle defaults for hints and go from there.

Question about the Initialization Parameters Information in the Alert.log
Hi, All -
What is the correct answer for the following question.
Specifically, what information does Oracle provide you with in the alert.log regarding initialization parameters?
a. Values of all initialization parameters at startup
b. Values of initialization parameters modified since last startup
c. Values of initialization parameters with non-default values
d. Only values of initialization parameters that cannot be modified dynamically.
I think the answer should be B, but I would like to confirm.The answer is C
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/process.htm#sthref1633
The alert log is a special trace file. The alert log of a database is a chronological log of messages and errors, and includes the following items:
All internal errors (ORA-600), block corruption errors (ORA-1578), and deadlock errors (ORA-60) that occur
Administrative operations, such as CREATE, ALTER, and DROP statements and STARTUP, SHUTDOWN, and ARCHIVELOG statements
Messages and errors relating to the functions of shared server and dispatcher processes
Errors occurring during the automatic refresh of a materialized view
The values of all initialization parameters that had nondefault values at the time the database and instance start

Minimum initialization parameters that need to be specified
During Database Creation, will specifying these initialization parameters be enough:
db_name= mydb
control_files = ("C:\ORACLE\PRODUCT\10.2.0\ORADATA\MYDB\CONTROL01.CTL","C:\ORACLE\PRODUCT\10.2.0\ORADATA\MYDB\CONTROL02.CTL","C:\ORACLE\PRODUCT\10.2.0\ORADATA\MYDB\CONTROL03.CTL")
db_block_size=8192
undo_management=AUTO
Also, is there an order in which these need to be specified ?

Questions regarding *dump_dest parameters and fast_recovery_area
Hello,
I just installed a fresh new 11.2.0.2 Database on Solaris 10.
Everything straightforward on the parameter side!!! I tried custom install as well as general purpose template. When installing with DBCA, I set every parameters around DB Name in lowercase name.
With this, questions are popping in my mind regarding some parameters after installation.
First, %dump_dest parameters contains in path, two times the db name (ocpdb in my case):
background_dump_dest /u01/app/oracle/diag/rdbms/ocpdb/ocpdb/trace
user_dump_dest /u01/app/oracle/diag/rdbms/ocpdb/ocpdb/trace
core_dump_dest /u01/app/oracle/diag/rdbms/ocpdb/ocpdb/cdumpIs it normal to have ..../rdbms/dbname/dbname/..... as path, with dbname/dbname ??? Why?
Second, the question regarding the directory structure under fast_recovery_area (new term for flash_recovery_area). The directory structure:
oracle@enalab13:/u01/app/oracle/fast_recovery_area$ ls -l
total 2
drwxr-x--- 2 oracle oinstall 512 2010-10-28 19:53 ocpdb
drwxr----- 5 oracle oinstall 512 2010-10-29 07:44 OCPDB
oracle@enalab13:/u01/app/oracle/fast_recovery_area$ ls -l ocpdb
total 9528
-rw-r----- 1 oracle oinstall 9748480 2010-10-31 21:09 control02.ctl
oracle@enalab13:/u01/app/oracle/fast_recovery_area$ ls -l OCPDB/

drwxr----- 5 oracle oinstall 512 2010-10-31 03:48 archivelog
drwxr----- 3 oracle oinstall 512 2010-10-29 07:44 autobackup
drwxr----- 3 oracle oinstall 512 2010-10-29 07:43 backupsetWhy am I having a subdir with dbname in uppercase AND in lowercase? Should I specify dbname in uppercase at db creation to have all files under the same directory, or in lowercase? Or, is it normal?
I want to know how to do it well before reinstalling a fresh database.
Thanks
Bruno

Database Initialization Parameters Removal list 9iR2
I have seen Oracle Metalink Document: Database Initialization Parameters and Configuration for Oracle Applications Release 11i Doc ID: Note:216205.1
https://metalink.oracle.com/metalink/plsql/f?p=130:14:654135795036791041::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,216205.1,1,1,1,helvetica#9iR2
This document has a removal list and states that these parameters should be removed from the database initialization parameters file for 9iR2, while I can see some of the parameters being used which are hash_area_size, sort_area_size and optimizer_mode.
Please clarify.
Thank you
AdithYou would need to set "hash_area_size" and "sort_area_size" if you have 8.1.7.X database. For 9i and 10g you do not need to set them, and this is exactly what is mentioned in the note.
If you check "Release-specific database initialization parameters for 9iR2 (9.2.0.X)", you will find the following:
As of 9i, the automatic memory manager is used. This avoids the need to manually tune sort_area_size and hash_area_size -

Initialization Parameters for JSPs ??
Hi All,
Is there any way to provide Initialization Parameters for JSP ??
If so how should it be done on Weblogic ??
Thanx In Advance,
Navaneeth.
Hi Navaneeth ,
If we want to provide Initialization parameters for jsp , we need to register a JSP as a servlet using the <servlet> element.
Registering a JSP as a servlet allows you to specify the load order, initialization attributes, and security roles for a JSP, just as you would for a servlet.
<servlet>
<servlet-name>MainServlet</servlet-name>
<jsp-file>/myapplication/critical.jsp</jsp-file>
<init-param>
<param-name>Name of the Parameter</param-name>
<param-value>Value of the Parameter</param-value>
</init-param>
</servlet>
go through the link ,you will find the documentaion on this

Passing Runtime initialization parameters to a Servlet
Hi all.
Plz.let me know, how do you pass runtime initialization parameters to a Servlet. Also, when do we need this approach. Thank You.Global parameters that may change should be passed as parameters so that the servlet doesn't have to be recompiled to make the change.
Here a global parameter is used to store a timeOut value. This value is written to every web page to force the page to refresh.
<web-app>
<servlet>
<servlet-name>
KioskServlet
</servlet-name>
<servlet-class>
KioskServlet
</servlet-class>
<init-param>
<!-- number of seconds of inactivity until timing out -->
<!-- 300 = 5 minutes -->
<param-name>timeoutValue</param-name>
<param-value>300</param-value>
</init-param>
</servlet>
</webapp> -
Session parameters / initialization parameters
what are session parameters? What are initialization parameters?
When we do: alter system set....., does need a restart of the machine? of Oracle instance?
thxInitialization parameters are those defined in your pfile or spfile (init.ora).
Some of these parameters can be redefined at session level:
see http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96536/ch14.htm#1014104
To get the parameter values, you can for example, run
show parameter <parm>
When we do: alter system set....., does need a restart of the machine? No
of Oracle instance?Yes if the parameter is static, no if the parameter is dynamic.

Access Initialization Parameters using jsp
Hi All,
Now I'm learning JSP . I want to access the initialization parameters using jsp. How to do it. I used the following code , but it shows null
initparameter.jsp
<html>
<body>
<h1>
<%
out.println("InitParameter Checking");
out.println(application.getInitParameter("param1"));
%>
</h1>
</body>
</html>I configured the following tags in my web.xml.
<servlet>
<servlet-name>initparameter</servlet-name>
<jsp-file>/initparameter.jsp</jsp-file>
<init-param>
<param-name>param1</param-name>
<param-value>value1</param-value>
</init-param>
</servlet>
Help me to resolve this problem
Thanks in advance,
mahestry overriding the jspInit method and then call getServletConfig() method and call getInitiParameter() on that ..infact the config implicit object would iachieve the same .i don't understand why it's printing null in your case .let me test and see

Initialization parameters not getting populated correctly during DBCA
This problem is observed on Oracle 10.2.0.1 Linux x86 and RedHat Enterprise Linux 4 ES Update 5.
I tried to use DBCA template file to create an Oracle database (see below for the template file content). The DB creation was successful, but the initialization parameters did not get populated into /oracle/u01/app/oracle/admin/ora10g/pfile/init.ora the way I would expect.

Right after DB creation using DBCA, I would expect to see the following initialization paramaters populated in /oracle/u01/app/oracle/admin/ora10g/pfile/init.ora file that match the values I specified in the template file, but it appears that some initialization parameters are either not populated or incorrectly populated.
db_cache_size=1g
(this parameter entry is missing, not getting popultated at all)
sga_target=1600m
(sga_target populated with 1211105280)
pga_aggregate_target=1g
(pga_aggregate_target populated with 403701760)
shared_pool_size=128m
(this parameter entry is missing, not getting popultated at all)
large_pool_size=0
(this parameter entry is missing, not getting popultated at all)
java_pool_size=0
(this parameter entry is missing, not getting popultated at all)
log_buffer=64000000
(this parameter is correctly populated)
transactions=610
(this parameter is correctly populated)
recyclebin=OFF
(this parameter entry is missing, not getting popultated at all)
cursor_sharing=EXACT
(this parameter is correctly populated)
Does anyone know why some initialization parameters did not get populated or incorrectly populated into init.ora?
Thanks in advance.
KenLikely dbca currently uses the spfile to store the parameters, as you should do too.
Apart from that the pfile Oracle uses is located in $ORACLE_HOME/dbs/init<sid>.ora
It is possible this file is soft-linked to the file you mention.
If it isn't the file you mention is not being used at all.

Recommended database initialization parameters databases for OBIEE
Hi ,
We are implementing OBIEE. We created 11gR1 (11.1.0.7) databases - one for datawarehouse and second for ETL repository. Can anyone please suggest the recommended database initialization parameters for the same. I searched metalink and got for EBS (11i/R12) and not for OBIEE.
Also, if you have any best practices documents for OBIEE, please provide the link.
Thanks in advance for your helpYou need to look for OBIA (Apps) not OBIEE:

Which are the initialization parameters that can be replaced by Environmet ariables
If I am connecting to SQL Plus from a command window(cmd), which are the variables that I can set in Environment, so that it overrides the values set in init.ora file.
For eg I can SET the following environment variables using a batch file
SET NLS_DATE_FORMAT=RRRR-MM-DD
SET NLS_LANGUAGE=US.AMERICAN.ISO***
Now when a new SQL session starts this values are set in the new session.
Can I know which other Oracle initialization parameters can be set in a batch file.http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/nav/initora.htm
