• There the init.ora parameters cannot be changed at all?

  DB version: 11 GR 2

  We have the following two types of initialization parameters

  Dynamic - which can be changed without a rebound in DB (example CURSOR_SHARING)
  Static - which can be changed with a rebound in DB (example MEMORY_MAX_TARGET)

  The two types of init parameters listed above can be changed with or without a rebound in the DB. There are initialization parameters that cannot be changed at all with or without a rebound in DB?

  Maybe it does.

  The value of DB_BLOCK_SIZE in effect at the time you create the database determines the size of the blocks. The value must be set to its initial value.

  
  

• set the database parameters using the init.ora file

  Hi all
  
  I'm working on a product of oracle (BI Apps), it gives a setting recommended database values in an inti.ora file. How can I apply this file to my database? in other how can words I use the values of the recommended settings in this file?
  
  Thanks for your time.

  Hello

  Try this:

  (1) connect to your database as a SYSDBA
  (2) issue: CREATE PFILE='/tmp/pfile.ora' OF SPFILE;
  (3) /tmp/pfile.ora to modify and add some references in your init.ora requests file - or update the current entries if those that already exist.
  (4) stop your database.
  (5) start your database in restricted using the new /tmp/pfile.ora mode to see if the settings are ok and if your database will start with them. (If he - go to 6), if no, go to 3)
  (6) question: CREATE SPFILE FROM PFILE='/tmp/pfile.ora'
  (7) judgment of the database
  (8) start as usual-, this will use the spfile with the changes.

  Nice.

  Note:
  Step 2) assumes that you are on * NIX and are actually using a spfile in your database already...

• DataGuard init.ora

  Hi all

  9i

  RHEL5

  Can help you identify what are the critical important parameters that will be inside the primary and standby init.ora?

  My point is, because there is a passage such as the role of the two database are inverted or exchanged.

  Then, I conclude that all of the settings contained in the primary and standby must me the same or equal?

  1. for example: standby mode parameter > lock_name_space = STBY

  I can also put it in the primary as > lock_name_space = PROD?

  2. What is the difference between the parameter:

  LOG_ARCHIVE_DEST_1='LOCATION=/U02/oradev/devdb/9.2.0/dbs/arch'

  and

  STANDBY_ARCHIVE_DEST = /u02/oradev/devdb/9.2.0/dbs/arch

  3. is it possible to place these 2 settings on standby and primary?

  LOG_ARCHIVE_DEST_STATE_1 = enable

  LOG_ARCHIVE_DEST_STATE_2 = enable

  Thank you all,

• Values recommended for installation of PROD init.ora

  Hi all
  

  -Assuming that I am using a 64-bit version of Oracle, 
  -that there is nothing else running on the server, 
  -that there will be no other databases on the server, 
  -that I have substantially more data on disk than I have RAM, 
  -and that I am using 11g. 

  I want to put in place an 11g database. The specifications of the server is OEL 5.6 with 12 GB of Ram and a Quad Core processor.
  There will be 200 users simultaneously access the database. I understand that 10g and 11g are 'auto adjustment '.
  So in this respect that I still have to change the values in the default init.ora?
  
  Can you give me example of your init.ora PROD template?
  
  Or maybe since my RAM is 12 GB, I put just the 'target LMS = 8 GB' and the database will be good?
  
  
  Thank you

  This will help you you also for memory management http://docs.oracle.com/cd/B28359_01/server.111/b28310/memory003.htm

  SESSION_CACHED_CURSORS

  Oracle monitors the SQL statements that are submitted for each session. If it detects that the same statement has been presented several times, it moves of the statement in the cursor cache and leaves the cursor open for future reuse. The parameter SESSION_CACHED_CURSORS controls the number of cursors allowed in the cursor cache.

  The default value for SESSION_CACHED_CURSORS varies with the release of Oracle. If your instance is not configured to cache at least 50 sliders, increase the value of this parameter to 50.

  OPEN_CURSORS

  The Oracle OPEN_CURSORS initialization parameter specifies that the number of cursors a session can have open at any time. The default value is 300. If the session is trying to open a new cursor, but already the number maximum open cursors, the error Oracle-1000 will be returned.

  Parameter that affects the Oracle statistics

  OPTIMIZER_MODE keep the default value for the parameter Oracle OPTIMIZER_MODE. For Oracle9i, the default is to choose; for Oracle 10 g, it is all_rows.

• How to configure the automatic height parameter in init.ora

  Hi all
  
  While in a meeting, I heard the other dba recommend putting auto tune the database. Because our database has performance problem, and we cannot identify the problem.
  
  How configure you Auto-Tune in init.ora? I just thought that this is the default when you install 11g DB.
  
  
  Thank you very much.

  I don't know how you separate 'tuning the database', of 'update the application. Of course, the database has ever of performance issues, if no request ever question him. But that does not translate a useful database.

  Can you share me experience when tuning the init ora gave to solve your problem of performance? drastically.

  I've seen many cases where to throw additional RAM to a problem (i.e. increasing the SGA_TARGET, PGA_AGGREGATE_TARGET, MEMORY_TARGET, etc.) generated significant performance improvements. Optimizer of various related settings can also have a significant impact on the performance of the applications. Which is not to say, of course, only a first not when confronted with a problem of performance should be to try to adjust the parameters of the system. When you have evidence of the monitoring of a particular process, however, that the system is starved of SGA, adding the SGA is a very useful thing.

• How2 (a) FIND good init.ora (b) or other files param on application server?

  I can't find the INIT. ORA file on my application server. I need to change some default settings.
  I looked here, I looked at the settings$ v who reported a "SPFILE"... and I looked at who, and there all these parameters with asterisk. and I don't know what that means. I wanted to just increase the number of links allowed DB on my test server.
  
  Could someone point me to fix the folder / file / documentation?
  Thank you.
  
  I note the following folder on my... running App Server 10 g in the Windows XP box.
  
  C:\OraHomes\ORAH1_DEV\database... where the SPFILE.
  C:\OraHomes\admin\UGOSREPS\pfile... that's where an init.ora file is...
  
  I added two lines in second file... in the topic... (num a 4, the default)
  and stopped and started in the DB, but... nada. parameters of v$ 4 instead of the following still says...
  
  Open_links = 100
  open_links_per_instance = 100
  
  ... but I'm afraid to touch the SPFile, because he put in a different form.
  
  In C:\OraHomes are 5 folders... Admin, Flash_Recovery_Area, OraData, ORAH1_DEV and ORAH2_BI.
  
  H1 is where we part 1 of the installation of the App Server (the part 'infrastructure', be it be a Forms / Reports Server 10 g), and in which we also added APEX).
  
  H2 is where we part 2 installation (real forms / reports part server... He insisted on not being under the same roof.)
  
  H1 and H2 are both available through OEM and seem to be running. But... we test things, so I know I need to change the settings... the first being the link settings.
  
  Could someone please offer a clue? TX,
  
  SM

  In order to change the system settings in the SPFILE you must issue an ALTER SYSTEM SET... SCOPE = SPFILE;
  i.e.

  ALTER SYSTEM SET open_links = 100 SCOPE = SPFILE;

  Restart the DB and recheck the values.

• How to create a single init.ora file for node 3 RAC to the title of the ASM

  All,
  
  Our environment is that a combination of different memory machines (V880, V490 & 250R) SUN of size.
  Establishing a single init.ora file that includes each of the memory of nodes in the SGA sizing is our desired configuration.
  Although we have created the file, the question becomes each NŒUD on the FCAC to use this unique setting
  file to launch its database instead of take the default init.ora file in the default directory (asm/dbs).
  
  As we conducted tests of failover, on restarting the instances they have restarted with bad memory
  definitions that have hung the nodes when it took more memory then what was available and the swap space has begun
  to develop.
  
  Steps to configure and activate the process, that's what I'm looking for.

• Install PT8.53 with Linux: the parameter file "init.ora" question CONTROL_FILE

  People,

  
  I install PeopleTools 8.53 with Linux. I'm confused on the parameter CONTROL_FILES in the file "init.ora". My SID is PT853 with the file "initPT853.ora". In the document setup 8.53 PeopleTools, there are 2 statements about CONTROL_FILES parameter like below:

  
  First of all, Page 161 task b 6-1-3: create an INIT < SID >. ORA file

  CONTROL_FILES = (/ filesystem1/cntrl1 < SID >, / filesystem2/cntrl2 < SID >)

  
  Second, Page 162 task b 6-1-4: creating paths of target directory

  
  CREATEDB10. SQL script:

  startup nomount pfile = $ORACLE_HOME/dbs/init < SID > .ora

  data file
  ' / u01/oradata / < SID > / system01.dbf' size 400M

  logfile
  ' / u01/oradata / < SID > / log01.dbf'M 70, size
  ' / u01/oradata / < SID > / log02.dbf'M 70, size
  ' / u01/oradata / < SID > / log03.dbf' size M 70;

  
  Control file references:
  control_files = ("" / u01/oradata/test92/control01.ctl "," / u01/oradata/test92/control02.ctl "," / u01/oradata/test92/control03.ctl "")

  
  When we created PeopleTools 8.53 of database using $PT_HOME/setup/PsMpDbInstall/setup.sh, we need to specify the mount point for the scripts createdb.sql, the utlspace.sql and the xxddl.sql. I use / U01 for all 3 scripts and create the directory/u01/oradata/PT853/manually.

  
  My questions are:

  Firstly, should the 2 items "/ filesystem1/cntrl1 < SID > ' and ' / filesystem2/cntrl2 < SID > ' CONTROL_FILES be the same with the directory path/u01/oradata/PT853/created manually?

  Second, should "/ filesystem1/cntrl1 < SID >" be changed to "/u01/oradata/PT853/cntrl01PT853.ctl and" / filesystem2/cntrl2 < SID > "be changed to" / u01/oradata/PT853/cntrl02PT853.ctl "in my case?

  Thirdly, how to create 2 files 'cntrl01PT853.ctl' and 'cntrl02PT853.ctl '? What are their contents?

  Thank you.

  I believe you are trying to create a demo database without understanding of basic on the RDBMS - your last question (to the control file) suggests.

  Work with your DBA on the part of database creation.

  Please go through the oracle database documentation to get a basic understanding of different files in oracle.

  Now, to answer your questions.

  1. Yes, anything you give in the init ora for parameter control_files file previously should exist while you run your createdb10.sql

  2. change any way you plan make the db files resident. Suppose you want the database in a path like/path/to/database/MYDB - to give him.

  3. you create control separately (in your case) files, the path/name of the file is taken from the init ora file and created as you run create sql db
  Content of the control file is in binary format: this is the heart of a database, holds all the information on the database, the name of db, file system, places change number etc...

  Please check with
