Instances where the control file needs to be backed up

Oracle Version --> 11G
Control file needs to backed up
1. When you add or rename datafiles
2. Add or Drop redo log members
3. Dropping tablespaces
4. After any ALTER DATABASE commandAre there any more instances where we have to backup the control file?

"set controlfile autoback on" is your friend.

SAP data extraction mapping, where the JCO files need to be copied?

Hi All,
I have the following environment.
OWB client: Windows7
OWB server: Linux x86_64
SAP Server: Windows Server 2003
I need to create OWB mapping to extract data from SAP to Oracle target.
Please let me know what are the JCO files required and where do i need to copy them?
Do i need to copy them on both the owb client and server or is it enough to copy them on the client machine alone?
Thanks and Regards,
Pnreddy.

OWB client isn't supported on Windows 64-bit, just wanted to let you know since you mentioned Windows 7..
For the windows you will require 3 files sapjcorfc.dll, librfc32.dll and sapjco.jar. You can get them from the SAP install cd or download them from http://service.sap.com/connectors for your SAP version. You will need to have a SAPnet account to do that.
You can place the files sapjcorfc.dll and sapjco.jar in OWB_HOME\owb\lib\int, and librfc32.dll in OWB_HOME\owb\bin and also set the PATH to reference this directories.
For linux you will need librfcccm.so, libsapjcorfc.so and sapjco.jar. Also set the LD_LIBRARY_PATH to reference these files locations.
If you are only extracting metadata from SAP then you need it only on the OWB client but if you plan to execute ABAP programs on the SAP system you will need to set it up on the server side.

Need help in writing the control file for SQLLOADER

Is it possible to error out the Sqlloader in case the data fields in the data file for a row are more than the fields stated in the control file?
i.e. My data file is something like
aaa,bbb,cc
dd,eee
And my ctl file has just 2 columns in it. Is it possible to write a control file which will cause the Sqlloader to error out?
Thanks...

Restore - filename for datafile is missing in the control file

I am practicing RMAN recovery procedures and I encountered a problem that I do not know how to solve.
1) I took a hot backup of my test database.
2) Create tablespace TS_DATA_TEMP
3) Deleted tablespace TS_DATA which had 2 datafiles
4) Created tablespace TS_DATA with 1 datafile
5) shutdown database
6) logged into RMAN in nomount
7) restore controlfile from autobackup;
8) alter database mount;
9) restore database;
RMAN> restore database;
Starting restore at 22-AUG-08

So i'm not sure what the problem is. Datafile TS_DATA.dbf is located in the control file but i'm getting the error: the filename for datafile 5 is missing in the control file.
Suggestions on what's wrong with the control file?

I found my mistake; a newbie error.
I did not know I needed to include in my restore command the 'until' option when doing incomplete recovery. I only included the 'until' option in the recover command:
original command
restore database;
recover database until sequence =123;
should be
restore database until sequence = 123;
recover database until sequence =123;
I usually run the command using a RUN block with a SET UNTIL SEQUENCE but this case I used the single commands separately.
RUN
+{+
SET UNTIL sequence 123;
RESTORE DATABASE;
RECOVER DATABASE;
+}+

In case of a DB crash what happens to the status of the Control File

When a DB is crashed will the Control file that exists in the OS also get corrupted, What happens to the Data Files , how to recover the Control files and Data Files , the DB in case there isn't any Backup media or any Dump available on the DB.

The only one way to recover a database is to be in archivelog mode.
And if I said about recover stricto sensu, that's because even in noarchivelog mode we need to use the command recover until cancel before an open with resetlogs option, even if we haven't any redo/archive logs. That fake a recover, this is what we say a mimic recover. Which is not a recover stricto sensu like it can be the case with archivelog mode.

Prevent Instance Shutdown When Control File Can't Be Written To

Our instance keeps shutting down when the system's backup utility backs up the control file (and once an index file) and locks the file. This also occurs when virus scanning. I was wondering if there was a parameter to set to have DB Writer try more than once to write to a file before aborting (and shutting down our instance).
Any help would be appreciated.
Thanks in advance.

SQL Loader: refer datafile name in the control file

Hi All:
Database: 10GR2
I have a table as following:
test (
filename varchar2(100),
mydata varchar2(1000)
I am using sql loader to populate data for this table. I also need store the datafile name to column test.filename as part of dataload. How to refer datafile name in the control file?
Again, I am processing multiple files in a batch mode. I need store datafile name in filename column so that I can know which "mydata" come from which datafile.
Thanks in advance!
Kevin

As Bravid says, you can't do that from within SQL*Loader, unless the control files are dynamically generated by a script and the filename included as the default value for that particular column as a hardcoded literal.
It's easier if you use external tables as the table definition contains the "location" which is the list of filenames it is accessing, and the value can be queried as well as being dynamically changed (though if you're dynamically changing it, then you'll programatically know the filename anyway. hint hint!)

FMS - change directory where the log files are located?

I want to change the logs files directory from:
C:\Program Files (x86)\Adobe\Flash Media Server 3.5/logs
to:
D:\fmsLogs
Please halp me to understand...
in adobe in:
Home / Flash Media Server 3.5 Configuration and Administration Guide / XML configuration files reference
it says:
in Logger.xml in Directory
Specifies the directory where the log files are located.
By default, the log files are located in the logs directory in the server installation directory.
Example:
<Directory>${LOGGER.LOGDIR}</Directory>
what this meens: ${LOGGER.LOGDIR} ?
in order to change the logs files directory from:
C:\Program Files (x86)\Adobe\Flash Media Server 3.5/logs
to:
D:\fmsLogs
do i need to write this:
<Directory>D:\fmsLogs</Directory>
or what do i neet to write?
it is totaly not understandable from this example...
big thanks for any halp
cheinan

You can change LOGGER.LOGDIR in fms.ini to your preferred location i.e. D:\fmsLogs and restart FMS.
Now if you want to change for individual logs - you can change in Logger.xml - by default logger.xml will use value from fms.ini

Delete the control file

Solaris 9 Oracle 9i
If one has got 2 sets of the control file eg control01, control02. can one delete one set if one needs space desperately and have a backup copy somewhere?
Thanx.

NPD wrote:
so this means it can be deleted if one wants toIf you could, it is highly not recommanded. You'd go to a not safely situation (imagine you lose the other one for some reason...). Furthermore, controflile are not Giga file size, I'm pretty sure you'll gain almost peanuts of space by removing a controlfile.

Re createing the control file

alter database backup controlfile to trace;
How do I re create the control file using what's in trace(Oracle 9i Solaris 9)
Thanx.

See Note 1012929.6 How to Recreate the Controlfile, the trace contains the syntax to recreate the controlfile, you can copy the contents to a sql file such as newctl.sql, edit the contents removing the header and make other changes such as increasing maxlogfiles, then run the sql file.

PS Why do you need to rebuild the controlfile?

How can i validate the data in the control file?

Consider that the SQLLoader reads the Input data File from the path and it loads the data into the tables based up on the descrition specified in the control File.
First, the table to be filled is created:
create table sql_loader_1 ( load_time date, field_1 Numeric, field_2 varchar2(10)
Sample Control File :
load_1.ctl
load data
infile 'load_1.dat' "str '\r\n'"
insert into table sql_loader_1
load_time sysdate,
field_2 position( 1:10),
field_1 position(11:20)
Note that the positions 11 through 20 are loaded into field_1 and positions 1 through 10 into field_2. The field load_time is filled with the current time (sysdate) of the load.
Here's the data. The name of the file (load_1.dat) had been specified with the infile statement in the control file.
load_1.dat
0123456789abcdefghij
foo bar
here comes a very long line
and the next is
short
Here i want to validate the field_1 (Numeric Datatype) since the data file contains the character value (i.e)abcdefghij

Can I set an mx control property globaly for all instances of the control.

Is there a way of setting the value of a variable on a control for all instances of the control in the application?
For example, I have several instances of an mx:Label and I want to change the enabled property for all instances at once rather than refer to each one individually by id.

One way is to subclass Button and change its enabled getter to watch some static property. You don’t really want to change Button itself because Buttons exist in lots of places like ScrollBars.

How can I find out where the Library files currently used by iTunes are located?

I have had a bit of a nightmare sorting out my iTunes files so I have various versions of Library files all over the place. How can I tell where the Library file that iTunes is currently using is located? In Preferences I can see the Library "Name", but I don't think that is much help. Preferences also shows where my i-Tunes media folder is but not where the Library files are.
Any help greatly appreciated.
J

Ah, I was assuming you would search in Finder and display some details. All alternative approach is to Option start iTunes and click the Choose option. It should show a file selection box targeted at the folder of the currently active library.
