Spfile creation

my spfile had been corrupted and i dont have any pfile so tell me what to do now?? how can i startup the database now??
and tell me can opening a binary file using vi editor and performing some changes and saving them can corrupt an spfile??
i had changed the entry local listener

If you do not have an rman backup of the spfile, you can recreate a pfile from your alert log. Every time the database starts, all non-default parameters are logged to the alert log. Locate those lines and save them to a pfile. Then use that pfile to re-create your spfile.

Error in spfile creation

Hi,
I am getting this error while creating spfile
SQL> CREATE SPFILE FROM PFILE='d:\oracle\ora92\database\initOrmrep.ora';
CREATE SPFILE FROM PFILE='d:\oracle\ora92\database\initOrmrep.ora'
ERROR at line 1:
ORA-01078: failure in processing system parameters
LRM-00111: no closing quote for value 'd:\oracle\'
Is there any length restriction to the parameter to pfile? Even then y this error?
Thanks and Rgds
Muneer

Are there any syntax errors or missing quotes in the file d:\oracle\ora92\database\initOrmrep.ora?
Can you startup your database successfully using:
SQL> startup pfile=d:\oracle\ora92\database\initOrmrep.ora

Which one is the alias here ?

Grid version: 11.2.0.3
Platform : Oracle Linux 6.3
If I manually name the following redo log file as shown below without depending on OMF
SQL> ALTER DATABASE ADD LOGFILE MEMBER '+RL_DG/orcl/onlinelog/redo3b.log' to group 3;
Database altered.
From ASMCMD> ls -l output , I can see another file being pointed to redo3b.log like
redo3a.log => +RL_DG/orcl/onlinelog/group_3.257.831130475
Which one is the ASM alias here ?
redo3a.log
or
+RL_DG/orcl/onlinelog/group_3.257.831130475 ?

+RL_DG/orcl/onlinelog/redo3b.log is the alias here. The 'real' file which ASM has internally created for your alias is +RL_DG/orcl/onlinelog/group_3.257.831130475
All filenames in ASM are created supposedly with OMF. When you manually specify a name , ASM will create the actual file with system generated file name. spfile creation in ASM is a classic example for this.

About spfile creating in oracle 10g while creating a new database

hi everyone,
i had this problem while i was creating a new database in oracle 10g.when running the database script, it gives an error about invalid option for create temporary tablespace. is it necessary to have an spfile created in 10g. when the script was not working,we tried to create spfile which gives error tht it does not match the parameter db_name. its taking the default db_name=orcl itself..tis not taking our new db name.
im creating it manually through sql prompt not through DBCA.the problem is that its still accepting the default db name. please send me the solution with syntaxes.
thanx

first of all, thanx for giuding me as im a student doing a course in this
what abt the creation of spfile.. in a documentation for steps in creating database, they have mentioned it as recommended in creating spfile.here are some notes regarding this ....for oracle 10g
Step 5: Create a Server Parameter File (Recommended)
Oracle recommends that you create a server parameter file as a dynamic means of maintaining initialization parameters. The server parameter file is discussed in "Managing Initialization Parameters Using a Server Parameter File".
The following script creates a server parameter file from the text initialization parameter file and writes it to the default location. The script can be executed before or after instance startup, but after you connect as SYSDBA. The database must be restarted before the server parameter file takes effect.
-- create the server parameter file
CREATE SPFILE='/u01/oracle/dbs/spfilemynewdb.ora' FROM
PFILE='/u01/oracle/admin/initmynewdb/scripts/init.ora';
SHUTDOWN
-- the next startup will use the server parameter file
EXIT
the error : db_name does not match with the parameter.
its still taking the default orcl database name

Please read any error message carefully, prior to posting.
**ORA-04031: unable to allocate 38410272 bytes of shared memory (*"large**
**pool"*,"SEQ$","QERHJ hash-joi","kllcqc:kllcqslt")**
Oracle is trying to allocate memory in the large pool, and the large pool is too small.
The sort_area_size has nothing to do with it.
Also there is no gain in setting the work_policy to manual, as Oracle will allocate memory beyond pga_aggregate_target automagically.
There is also no gain in setting db_file_multiblock_read_count, as Oracle will adjust that automagically.
Sort_area_size is in bytes, as documented, and it is your value in the spfile/init.ora which is the default or which you have set.
You can read about this in the documentation which is online at http://tahiti.oracle.com

Custom List Form creation using Powershell - SharePoint 2013

Hi,
I have a custom List called 'IssuesList' with 4 fields - "IssueTitle","IssueID","IssueDesc","Status"
While displaying display form I should show 3 fields expect Issue ID i.e. IssueID should be hidden.
and on edit form only Status field should be editable. So using SharePoint designer I created respective Edit form and display forms and changed XSLT to control the display mode on the fields.
I have everything scripted in powershell till now - creation of custom list, publishing pages, webparts etc. however I am looking for how to provision or associate these 2 list forms with IssuesList after I create the list in new site.
I have restrictions on using wsp and site/list template due to business needs. So I need to know if there is any way I can upload these 2 files after I create custom list in powershell and associate them as defaultdisplay and defauteditforms?
Please advise.

Hi,
Per my understanding, you might need to apply these custom forms to a list after list creation using PowerShell.
With PowerShell with SharePoint Object Model, we can hide fields on list forms.
The similar thread below with code snippet will provide more information about this:
https://social.technet.microsoft.com/Forums/en-US/ee6fc2eb-197f-4144-94fa-8a4e438675d9/hide-a-field-from-edit-form-list?forum=sharepointgeneralprevious
If there may be other requirements except for hiding fields, as you have limitation on using custom solution package(which should be preferable in such scenario),
a workaround I can provide is that, after list creation, you can add Content Editor Web Part contains the CSS style or JavaScript to the form pages of a specific list, it will help you hide/disable the specific elements, this can be achieved programmatically.
The code below can add a Content Editor Web Part to the DisplayForm of a list(though in C#):
public static void AddCEWP()
SPLimitedWebPartManager manager = null;
SPFile file = null;
using (SPSite site = new SPSite("http://sp"))
using (SPWeb web = site.RootWeb)
try
web.AllowUnsafeUpdates = true;
file = web.GetFile(web.Url + "/Lists/List018/DispForm.aspx");
manager = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
ContentEditorWebPart webPart = new ContentEditorWebPart();
XmlDocument xmlDoc = new XmlDocument();
XmlElement xmlElement = xmlDoc.CreateElement("HtmlContent");
//xmlElement.InnerText = "<strong>Hello World!</strong>";
//write the custom CSS style or JavaScript here
string content = "<style>your custom style here...</style>";
xmlElement.InnerText = content;
webPart.Content = xmlElement;
manager.AddWebPart(webPart, "Top", 0);
manager.SaveChanges(webPart);
web.Update();
catch (Exception ex)
//Utility.SPTraceLogError(ex);
finally
if (manager != null)
manager.Dispose();
web.AllowUnsafeUpdates = false;

Reg: Creation of PFILE

Hi
I'm a fresh DBA.I'm new to this field and learning Things.Unknowingly i deleted the pfile and made a shutdown to my database..... When i'm trying to start the Database i'm unable to start it. is there any way to create a new pfile..........Please find me the way...
Advance Thanks

Hi,
What is your Oracle version ? Have you create a spfile before delete pfile ? If the response is no, you need to recreate a pfile manually.
=> It a good way to have a backup of all database files, including pfile (or spfile).

Database creation with ASM using dbca

hi all,
i found the steps to create the database using ASM diskgroup.
but i received errors when configuring the FRA(flash recovery area), DBF(normal), +ARCH(archival dest),
i tried atleast 2 to 3 times from scratch but found the same error....................

•     Start up the server OraWorld1
•     Go to Disk Management and you will be prompted with a screen which should display all five disks with a check mark. Accept defaults and Click next.
•     On second script all five will be unchecked, click Next
•     Press Finish to complete and you should see all 5 disks as Type Basic Unallocated. For each of the disk perform:
1.     Right click, New Partition, Extended Partition and Finish
2.     Right click, New Logical drive, Do not assign drive letter nor partition it.
3.     From command prompt type Diskpart and enter Automount enable.
4.     From command prompt, configure basic CRS services as
5.     C:\oracle\product\10.2.0\db_1>localconfig add
6.     C:\oracle\product\10.2.0\db_1>localconfig add

5.     ORCLDISKASMARCH \Device\Harddisk5\Partition1
Now make Change Disk Discovery Path as Null and you should see all disks.
Now create Disk groups as :
ARCH \\.\ORCLDISKASMARCH External 1GB
REDO \\.\ORCLDISKASMREDO External 1GB
FRA \\.\ORCLDISKASMFRA External 2GB
DBF (MAIN GROUP WITH 2 SUB-GROUPS) Must create as Normal Redundancy
DBFP \\.\ORCLDISKASMDBF1 External 2GB
DBFS \\.\ORCLDISKASMDBF2 External 2GB
You now have a running ASM instance on the server.
•     Checking ASM instance
You can always use DBCA to check settings of ASM.
Alternatively, go to command prompt:
Set ORACLE_SID=+ASM
Sqlplus /nolog
Connect sys/password as sysdba
Show sga (80MB)
Total System Global Area 83886080 bytes
Fixed Size 1247420 bytes
Variable Size 57472836 bytes
ASM Cache 25165824 bytes
SQL>desc You can then check C:\oracle\product\10.2.0\db_1\database for these files. You can also view v$parameter for all possible values for ASM instance.
+asm.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'#Manual Mount
*.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'
*.asm_diskstring=''
*.background_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\bdump'

*.instance_type='asm'
*.large_pool_size=12M
*.remote_login_passwordfile='SHARED'
*.user_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\udump'
You can change some of the values like large pool and even db cache size. You can also manually create the disk group as:
Create diskgroup DBF NORMAL redundancy
Failgroup flgrp1 disk ‘\\.\ORCLDISKDATA0’, ‘\\.\ORCLDISKDATA1’
Failgroup flgrp2 disk ‘\\.\ORCLDISKDATA2’, ‘\\.\ORCLDISKDATA3’;
Check Candidate disks:
select group_number, disk_number, mount_status, header_status, state, path from v$asm_disk;
Other useful queries:
Select group_number, name, total_mb, free_mb, state, type
From v$asm_diskgroup;
Select group_number, disk_number, mount_status, header_status, state, path, failgroup
From v$asm_disk;
You can use sql commands to perform most of the ASM tasks, however EM console can also be used here

Database creation in oracle 8.0.4

Hi,
I'm creating a database in Oracle 8.0.4. I choose the custom option to give all the parameters. One of these parameters is the password of internal user. I give it as oracle. After giving all the other parameters and then click on finish to create the database, i get ORA-01017 error and i'm being forced to abort the database creation.
After this error has occured, i've created another two databases with a different names and all went fine. I didnt have any problems while creating the databases. Again after the creation of the new databases, i tried to create the old database. Even then i got the same error.
can anyone let me know what might be the reason for this and the solution to overcome this problem.
Thanks in advance,
Jaikanth V Garlapati.

Found this in Oracle Doc,
NLS_DATABASE_PARAMETERS is the one you set when you do Create Database.
NLS_INSTANCE_PARAMETERS is the one you set in your spfile when you start instance.
So if you didn't set NLS_INSTANCE_PARAMETERS in spfile, then instance will start with NLS_DATABASE_PARAMETERS
And alter session will over write them all.
It's not new behavior in 10.2.0.4
==============================================
NLS Database Parameters
When a new database is created during the execution of the CREATE DATABASE statement, the NLS-related database configuration is established. The current NLS instance parameters are stored in the data dictionary along with the database and national character sets. The NLS instance parameters are read from the initialization parameter file at instance startup.
You can find the values for NLS parameters by using:
NLS Data Dictionary Views
NLS Dynamic Performance Views
OCINlsGetInfo() Function
NLS Data Dictionary Views
Applications can check the session, instance, and database NLS parameters by querying the following data dictionary views:
NLS_SESSION_PARAMETERS shows the NLS parameters and their values for the session that is querying the view. It does not show information about the character set.
NLS_INSTANCE_PARAMETERS shows the current NLS instance parameters that have been explicitly set and the values of the NLS instance parameters.
NLS_DATABASE_PARAMETERS shows the values of the NLS parameters for the database. The values are stored in the database.

Confusion over DBCA script generated for manual RAC DB creation

Version:11.2.0.4/RHEL 6.3
We would like to create our 3-node RAC DB manually. DBCA cannot meet our requirement because our redo log files, datafiles, tempfiles and control files are placed in a complicated manner . If we use DBCA , we will have to spend a lot of time configuring to our requirements after the DB creation.
I generated the DB creation scripts from DBCA (DB Name = BRCFPRD )
DBCA placed the db creation scripts in the specified directory in all the 3 nodes !!
They all have almost the same contents . The only difference being the instance name (BRCFPRD12.sql for Node2, ... etc).
Scripts in each node have the createDB.sql statement which has CREATE DATABASE "BRCFPRD" statement. Why is this ? The database need to be created only from one node. Then why did DBCA place createDB.sql in all nodes ?
I just want to run the script from just one node , say Node1 and it should create the 3-Node RAC DB. How can I do this manually?

Spfile in Oracle 9.2.0

One of the steps for manual oracle database upgrade from 8.1.7 to 9.2.0 include creation of spfile.
My question is: Do we really need to use spfile (server parameter file) and if yes - what the advantage(es) for using it?
Thank you,
Yelena

No, you do not need to use it. Upon startup, if Oracle cannot find the spfile (default location $ORACLE_HOME/dbs) then it will look for the pfile in the default location. But I can't think of any good reasons why you would not want to use the spfile, unless it's on a test system where it doesn't matter how often or when you bounce your instance to make changes take effect. The spfile allows you to dynamically set numerous parameters for the system that would otherwise require a shutdown to initialize. Once you start using it, you'll look back on the "old" way and think you lived in the stone age. Just use 'ALTER SYSTEM SET ... SCOPE=[MEMORY] | [SPFILE] | [BOTH]'
where 'MEMORY' means it is just active for your session; 'SPFILE' means it is written to the spfile and activated after the next restart; and 'BOTH' . . . well, I4ll let you figure that one out.
One of the parameters you cannot change dynamically is the large_pool. There are probably more, if anyone knows them please help me out here.
Hope this helps.

Creation parameters not taking effect after database creation in 10.1.0.4

I created a database using DBCA, changed the default nls settings, then finished the database creation.
The alert log reports the parameters as different than the defaults
However, when starting the instance, the nls parameters are only set at the instance level and not the database level.
Has anyone seen something similar in 10.1.0.4?
Thanks

NLS Dynamic Performance Views
OCINlsGetInfo() Function
NLS Data Dictionary Views
Applications can check the session, instance, and database NLS parameters by querying the following data dictionary views:
NLS_SESSION_PARAMETERS shows the NLS parameters and their values for the session that is querying the view. It does not show information about the character set.
NLS_INSTANCE_PARAMETERS shows the current NLS instance parameters that have been explicitly set and the values of the NLS instance parameters.
NLS_DATABASE_PARAMETERS shows the values of the NLS parameters for the database. The values are stored in the database.

ASM DG creation fails on sles11_x86_64 with 11gR1

Hi,
I have sles11x86_64 installed and using Veritas Volume manager raw disks for ASM but ASM dg creation fails with error mentioned below;

can some body help on this.
Also wanted to know the background process during ASM creation.

Instance creation

hi
Assume the operating system is unix.
I can create the oracle database by using :
create database .......
How about the instance?
Can I create it manually, or is it created automatically after database creation ?
Assume I can not use dbca

This issue once more has to do with basic architecture concepts, the instance is not created, the instance exists after you start it with the startup nomomount command, it does not have to do with running or not running oradim.
Oradim exists in windows environments only due to platform specific architecture issues. Oradim does not create the service, it is used to create the entries required to manage the instance, but it issues a startup command which is actually the one which will start the oracle instance and will mount and open the database.
In a windows environment you must create the windows service, it does not mean the oracle instance will be created. You can perform a simple experiment, change a critical value in the spfile a backup is required) just like db_name, then try to start the service, and you will see the instance is not 'created'. The windows service is not the oracle instance.
The term 'Create the Instance' is inaccurate, you must use 'Start the Instance' instead.
In order to keep things simple, just use the DBCA assistant to create the database, this will take care of the details. If you want you can ask DBCA to create a script, you can analyze this script later and perform reverse engineering to determine the commands to manually start the Oracle instance and create a database.
