Automatic EXP export of database 11gR1
Dear All,
I use to take backup daily of my database 11gR1 on Linux from my client window machine through exp comand.
I have to go on a leave for one week. I want to automate this procedure that export of schemas in database is taken automatically on daily basis. What is the easiest process to do this.
Regards,
Imran
You should use Oracle 11g Scheduler to automate your backup process
Please refer to below pages:

Where to run SQL statements in Oracle Database 11gR1 ?
Folks,
Hello. I have just installed Oracle Database 11gR1 and login to Database Control page. There are 4 tabs on the top: Database, Setup, Preference, Help and Logout.
I just create a table "table1" in "Database" tap. But I don't see anywhere to run SQL statement such as Select, Insert, Update.
Can any folk tell me where to run SQL statements in Oracle Database 11gR1 ?
Or
Can any folk provide a User Manual for Oracle DB 11gR1 ?You can run from a terminal or install an SQL client and connect from there.

Assuming you have an oracle OS user on Linux you can try typing sqlplus at you OS command prompt. Generally you will have a .bash_profile with setting like this:

TMPDIR=$TMP; export TMPDIR

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:
Example: EXP SCOTT/TIGER
Or, you can control how Export runs by entering the EXP command followed
by various arguments. To specify parameters, you use keywords:
Format: EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: EXP SCOTT/TIGER GRANTS=Y TABLES=(EMP,DEPT,MGR)
or TABLES=(T1:P1,T1:P2), if T1 is partitioned table
USERID must be the first parameter on the command line.

Exporting a database....
Hello,

Fernando.Hello,
I'd like export my Database to my user "DSV". How can
I do this ?
I'm using oracle 8i version...
Yours
Fernando.Your question is a little confusing. Technically you can't export/import a database to an user. Because user is part of a database not ves versa.
If you mean you have an existing user you want to import his objects to user DSV then you can use fromuser/touser parameter of import.
For example,
exp userid=user/pass owner=old_user file=dump
imp userid=user/pass fromuser=old_user touser=DSV file=dump -
Exporting full database...
Dear All,
While exporting full database objects of sys user are exported or not?
Please tell me in details.
Thanks In advance.
PSP.I agree all your point. But, what will you do when an object is dropped such as TABLE >when the DB is 5 T or more.
Would you do a PIT? would you?
I accept that we use this exp/imp as one way of data migration. It doesn't become it is a >migration tool not a backup tool.
Then why would ppl say it is a logical backup not as migration tool. ppl say we can use >this as one way for data migration.Then there's when your sounded backup plan comes in play.
We use to do a full exp every day from our small databases, and the retention policy is 14 days.
In the Biggest database a full exp is not possible due batch processing at night, so we take a home made incremental export for the big objects and the rest of tables.
In 10g i think you can set the flashback to 2 weeks and that's all we need. (ya its a lot of space but it depends on your policy and your database size).
I'm not against EXP/ IMP at all, but you cant rely on them other than getting back a table or a stored procedure from certain date.
what i've noticed is that lot of people use exp/imp in small databases and this is their main backup strategy, but when they start working with big databases this approach is just not enough.
This is why you have to work and review your corporate backup policy.
It doesn't matter if you are an excellent DBA, if you took 3 days (or more) to restore your database you are just not doing your work.
my 2c.
Edit:
May be i need to clarify something.
Physical backup is intended to fast restore your database from a crash.
Logical Backup is used to migrate data, even if its into the same database. -

I"m not sure why, but the utilities manual has been consistent over the versions about warning not to export "as sysdba"

venkat.What is your SGA settings? (especially streams_pool_size).
You can try to bump streams_pool_size to 100M if your current setting is below that.

Oracle Database 11gR1 Enterprise Manager Console Cannot Display in Browser
Folks,
Hello. I am running Oracle Database 11gR1 with Operaing System Oracle Linux 5. I have some issues regarding EM connects with the Database Server as below:
First, the default listener is LISTENER with standard port number 1521 and protocol TCP/IP.
Its corresponding service naming S1 is with port 1521 and protocol TCP/IP and hostname localhost.localdomain.
I run this listener in the following way:
Step 1: [user@localhost bin]./lsnrctl start LISTENER (This command runs sucessfully.)
Step 2: [user@localhost bin] ./sqlplus SYS/SYS as sysdba (This command starts sqlplus sucessfully.)
Step 3: [user@localhost sqldeveloper] ./sqldeveloper.sh (This command invokes SQL Developer sucessfully.)
But when start Enterprise Manager Console, it cannot connect with the Database. I do it in this way:
[user@localhost bin] ./emctl start dbconsole
The above command's output is:
https://localhost.localdomain:1158/em/console/aboutApplication
Starting Oracle Enterprise Manager 11g Database Control ... ...
When open the link https://localhost.localdomain:1158/em/console/aboutApplication in browser, this message comes up:
The connection to localhost.localdomain: 1158 cannot be established.
Thus, I add Port Number 1158 into both LISTENER and Service Naming S1. I run ./emctl start dbconsole again and get this message:
The connection to localhost.localdomain:1158 was interrupted while the page was loading.
In order to solve the above issue, I create another listener LISTENER2 and another Service Naming S2 with Port Number 1158 and protocol TCP/IP because
in my point of view, each listener only can have one Port Number(1521 or 1158) and its corresponding Service Naming (S1 or S2) need to have the same Port Number and Protocol (TCP/IP).
But when I run [user@localhost bin]./lsnrctl start LISTENER2, this message comes up: the listener supports no service.
From the message, it seems that LISTENER2 cannot work with its corresponding Service Naming S2 with Port 1158.
EM with Port 1158 cannot display in Browser.
My questions are :
First, Is there any relationship needed to be established between listener(LISTENER2) and Service Naming(S2) in order to display EM in Browser ?
Second, how do folks display EM in browser ?
Thanks.Folks,
Hello. Thanks a lot for replying. I do the following command: [user@localhost bin]$ wget http://localhost.localdomain:1158/em
The command returns the message:

Can you have a PDF fit on the viewer's screen automatically when exporting from InDesign CS4?
Can you have a PDF fit on the viewer's screen automatically when exporting from InDesign CS4?
If you were to upgrade to InDesign CS5 or CS5.5 and if you exported as Adobe PDF (Interactive), you could set the View settings for Page Layout and Zoom.
While, as Jongware points out, its possible for individual users to override that option (Preferences > Page Display > Default Layout and Zoom), the number who will actually do that is actually very tiny. -

Hi Linda,
The database version is 10g and OS is linux. Can we use filesize parameter for the export. Please advice on this.FILESIZE will limit the size of a file in case you specify multiple dumpfiles. You could also could specify multiple dump directory (in different FS) when given multiple dumpfiles.
For instance :
dumpfile=dump_dir1:file1,dump_dir2:file2,dump_dir3:file3...Nicolas.
