Is it possible to create a control file without the datafiles

Hi All,
Is it possible to create a control file without the datafiles?
on any OS or DB version
regards,
sachin

if I understand properly:
- you have a script to recreate the controlfile
- you have all of your database files backed up except your controlfiles
This should work as this is how we sometimes refresh dev databases:
1) restore the copies of the database files
2) recreate the controlfile
3) recover the database files to the desired point in time (if hot backup or archivelogs are available, otherwise, it would be as of the time of the backup)
4) add temp files to temporary tablespace(s)
The simpler solution would be to backup your controlfile at the same time as your datafiles (RMAN or o/s copy).
I hope I understood your question properly.

Is it possible to create an installation file, or JumpStart file, for iCS 2.x?

Is it possible to create an installation file using the
"setup -k" command for
iPlanet Calendar Server(iCS) 2.1? And is it possible to install iCS 2.1 with
JumpStart
from an installation server, or do I need to use the installation log?
<P>
The installer for iCS 2.x does not support silent installation (the
setup -k command). To install
iCS 2.x, the system administrator must run the installer directly on each
system where the calendar server is to be installed.
<P>
Silent installation may be supported on a future release.

Creating a Control File

I have a question about creating another control file. If I want to create another control file, do I need to put the values/paths of the current control files in the CREATE CONTROLFILE statement?

996403 wrote:
If I am wanting to create a new control file, do you recommend:
1. Use the Create Control file statementWhen to Create New Control Files:
All control files for the database have been permanently damaged/missing and you do not have a control file backup.
You want to change one of the permanent database parameter settings originally specified in the CREATE DATABASE statement.
These settings include the database name and the following parameters: MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, MAXDATAFILES, and MAXINSTANCES.
For example, you would change a database name if it conflicted with another database name in a distributed environment,
or you would change the value of MAXLOGFILES if the original setting is too low.
2. Copy an existing control file and then edit the parameter file?i will recommend 2nd (if you have healthy control file) if you want multiplex control files.

Regarding RESETLOG and NORESETLOG option while creating a control file

Hi,
I dont understand the need for resetlogs option while creating a controlfile for a db in NOARCHIVELOGMODE. I assume that reset logs clears all the redo log contents.
While taking a cold backup what I did was:
1. Shutdown instance
2. Copy all the files
3. Startup
Now I tried recovering the same database on a new machine (with different path btw.) coz of which i had to create a new control file. My question is: while restoring the database, do I need to create the control file with NORESETLOG or RESETLOG option?
When I tried using the NORESETLOG (NOARCHIVELOG) option I was able to recover the instance without any hassles.
ie
1. STARTUP NOMOUNT
2. CREATE NEW CONTROL FILE USING NORESETLOG (NOARCHIVELOG)
3. RECOVER DATABASE
4. ALTER DATABASE OPEN;
While the same thing with NORESETLOG (NOARCHIVELOG) option:
1. STARTUP NOMOUNT
2. CREATE NEW CONTROL FILE USING RESETLOG (NOARCHIVELOG)
3. RECOVER DATABASE USING BACKUP CONTROLFILE
This step asked me for some archivelogs which were not generated since the db is in NOARCHIVELOG mode.
I wonder why we require the RESETLOG OPTION SINCE A NORMAL SHUTDOWN PERFORMED BEFORE COLD BACKUP would have ensured that there is no redo information left in the redo logs.
Please let me know if I am thinking the incorrect way.
Regards and Thanx in Advance,
Raj

If you had a db running in noarchivelog mode and had to clone the db and rename it, the create controlfile stmt:
create controlfile reuse <db_name> needs to be changed to: create controlfile SET <db_name>, in which case the db can only be opened with resetlogs. Hope this answers your question

If it is not specified,Oracle creates one control file in a default locatio

Hi
The CONTROL_FILES parameter is not required when you create a database. If it is not specified,Oracle creates one control file in a default location,.
Where oracle create contol file default in this condition
Thanks

Can you try to create a database and see
FYI
It creates in $ORACLE_HOME\database folder..if not specified but in UNIX i think it will be under $ORACLE_HOME/dbs
Because i dont have UNIX right now to test it

How to dynamically create sqlldr control file using stored procedure

I am trying to dynamically create the control file (.ctl) and execute the same using a stored procedure.I would be passing the file name as a parameter to this procedure. How do I go about doing this?
The control file has the following structure. The file name (mktg) varies and is passed as an input to the stored procedure.
SPOOL mktg.ctl
LOAD DATA
INFILE 'mktg.csv'
INTO TABLE staging
FIELDS TERMINATED BY ','
TRAILING NULLCOLS
(COMPANY_NAME,
ADDRESS,
CITY,
STATE,
ZIP)
SPOOL OFF ;
sqlldr scott/tiger CONTROL= mktg.ctl LOG=mktg.log BAD=mktg.bad

We are using oracle 9i rel 2.
I have not had much success with the creation of log and bad files using external tables when they are being used within a dynamic sql.
Plz check this:

Is it possible to create a MPEG4 file that is still hi def?

Hello, I'm new to Compressor, having just installed Compressor 3.5. I have a short Final Cut hi def (1080i) video file that my son wants to upload as a hi def file on youtube. He tried uploading the Final Cut file, but it was too large for youtube (over 3 gig), and apparently they requested a mpeg4 file. I messed with Compressor last night and created a 952 MB file using the Hi Def folder in Setting. I also created a 252 MB file using the MPEG4 folder in Settings. But somehow I don't believe that the MPEG4 file is hi def.
Is it even possible to create an mpeg4 file in compressor that is hi def? If so, could you please tell me which setting to use?
Thanks so much, Bob

Does the 1280 X 720 indicate that it is definitely hi def?
By definition (no pun intended), 'high definition' is any resolution greater than 'standard definition.' Standard definition video in NTSC is 720x480 (NTSC rectangular pixels or NTSC 640x480 square pixels). Standard definition in PAL is 720 x576.
how is it possible to still have hi def, if the file is 1/9 the size of the original file?
For a watered down version of compression, some of the information for each pixel's RGB values are thrown out during the compression process. For example, in MPEG-2 compression (commonly used for DVD and broadcast TV), the first frame is an independent or "I" frame, containing all the data for each pixel's RGB value. The next 14 frames only contain the data for each pixel that changed from the I frame or from the previous frame. This group of 15 frames is known as a GOP (group of pictures). The 16th frame is another "I" frame and consequently starts another GOP.
In reality it's a heck of a lot more complex than that, but that's the basics of video compression. For a more detailed explanation, see: http://en.wikipedia.org/wiki/Video_compression

Creating acscii control file from binary control file

Hi,
We are in the process of cloning DB on a different server from cold backups taken on source server. The DBA forgot to take the backup of control file by dumping to trace using command
alter database backup controlfile to trace;
We have the cold backup files of control files.
Is there was to create ascii control file from those binary control file?
I am wondering if we can use any binary file editors like emacs to do this
Is there any other way to clone it without backup of control file?
TIA
andy

Apart from that I recommend you to have this thread on hand if you get any trouble duplicating the database.

Possible to create a JAR file from within a java app?

Is it possible to create a jar file from within a java application?
Can it be done more elegantly than by spawning-off another
process with the Runtime and exec() portions of the api?
Thanks
Scott

Thanks! I was mislead by the API notes for java.util.jar:
The JarOutputStream class is used to write the contents
of a JAR file to any output stream.
I was looking for a class or method to make jar files.
Seems this is it ;)
Thanks

Is it possible to create an "offline" file of company specific updates?

Hello everyone -
Wanted to know if and how it is possible to create an offline file(.cab) of our current, company specific Windows Updates. We currently use the stand alone SUS for all domain PCs.
I'd then like to apply this file to our current image, then capture it.
Currently our image is a bit dated and any deployment of this image will then have to "catch up" to all of our updates that we deploy, (around 300MB+ right now).
TIA,
randy

Are plugins able to create graphical controls children to the Acrobat/Reader application?

Hello,
in the documentation I read　
Acrobat Viewer layer
The Acrobat Viewer (AV) layer enables plug-ins to control Acrobat and modify its user interface. Using AV methods, you can, for example, add menus and menu commands, add buttons to toolbars, open and close files, display simple dialog boxes, and perform many other application-level tasks.
I ask if it is possible that a plugin creates a graphical control like others applications can usually do and put it as a legitimate child of the Acrobat/Reader application, for example over a pdf page, and get events and so on.
Thanks in advance

Sure.

System altered. Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function.

How to restore a control file without having its backup

Hi,
Can any one please suggest me how to restore a control file without having its backup.
Thanks

To add to what SB said, in years past the instructions for re-creating the control file manually were contained in the DBA Administration manual. It used to be and may still be common to be taking and saving a "backup control file to trace" for this purpose.
If you lost only the primary copy of the control file and it is an OS file then while the database is shutdown you can copy the secondary over the primary and then use if to start the database. If the control file is stored in ASM then there should be a way to perform the copy via ASM.
If you use rman for backups then a copy of the control file should be part of the backup process and you can retrieve it from the backup set then perform recovery using the backup control file though I do note the OP said something to the effect no backup exists. Still, I have knows of instances where the DBA did not realize that the backup set contained the control file and the spfile so I think this is worth mentioning just in case.

Export to PDF - Can a single report (rpt file) create multiple PDF files using the export command?

Post Author: markeyjd2
CA Forum: Exporting
Greetings forum members,
My question is, in its entirety: Can a single report (rpt file) create multiple PDF files using the export command, ideally one PDF file per DB record?
In my case; I have a Crystal Report that reads data from a DB table containing ~ 500 records. When I export the report to a PDF file, I get one PDF file, with ~ 500 pages.
What I would like to do is export the report to ~ 500 individual PDF files; One file per DB record. The file names would be based on the table's primary key.
Is this possible?

Post Author: Micha

Hi,
you need some lines of code, but its easy. Dependend on how to start the generation of your 500 PDFs, you can write an ASP page and start it via Web Browser, or a Windows Script and start it via scheduled job...
Here's an abstract of the ASP code I use:
First, you create a recordset (here: "rsc") which gives you the list of ID fields you want to export, then you create CrystalRuntime.Application object, then you loop through the recordset, open your report (here: "oRpt") and set login info. Then set the selectionformula, so that the report displays only the data of the current ID, e.g.:
oRpt.RecordSelectionFormula = "(" & oRpt.RecordSelectionFormula & ") AND {myTab.myVal}=" & rsc("myVal")
Then you export the report, move to the next record in recordset, and repeat the loop until recordset.EOF. Then you close recordset and connection.
