Is it safe to run expdp on a live database?

Can I run expdp on a live database? Will expdp take out any long-lasting locks that might hang normal application transactions (or does expdp just take a "snapshot" copy of the schema at a particular SCN)?

To answer your second question:
(or does expdp just take a "snapshot" copy of the schema at a particular SCN)?
expdp will not take a snapshow copy of the schema at a particular scn. expdp will export all partitions/subpartitions of a table at the same scnr, but could export different tables at different scns. If you need the complete expdp job to be exported with a consistent scn, your best bet is to use flashback_time or flashback_scn.

Best Policy to run open queries on LIVE Database

Hi Experts,
There are users who has RO access on Live database , they run open queries on Live database. Sometimes we have faced some issues on Live Database due to open queries and we can not restrict them to run as well. So would like to get your suggestion
to come up with best solutions ?
Shivraj Patil.

What issue do you have? One option is tuning the query, means create proper indexes to speed up the query..
But the user may run heavy query even being unaware that system consumes resources, for example
--A typical parallel query...
SELECT
p.ProductId,
p.ProductNumber,
p.ReorderPoint,
th.TransactionId,
RANK() OVER
PARTITION BY
p.ProductId
ORDER BY
th.ActualCost DESC
) AS LineTotalRank,
RANK() OVER
PARTITION BY
p.ProductId
ORDER BY
th.Quantity DESC
) AS OrderQtyRank
FROM bigProduct AS p
INNER JOIN bigTransactionHistory AS th ON
th.ProductId = p.ProductId
WHERE
p.ProductId BETWEEN 1001 AND 5001
GO

Though you can initiate the binary from your client side but for the file creation, there is no other way but to store it on the server side. So your best bet would be to get some space free on the server side of yours.

Getting - ORA-01403: no data found - When I Run expdp

Oracle database version 11.1.0.7.0 on Windows 32-bit.
When I run:

Connected to: Oracle Database 11g Enterprise Edition Release *11.1.0.7.0* - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

I turned on tracing like this:
1.) Set the Error Stack 1403 to know exactly which SQL is failing:-
SQL> alter system set events '1403 trace name errorstack level 3';
Re-ran the datapump export to reproduce the error then disable the events.
SQL> alter system set events '1403 trace name errorstack off';
The trace file, oddly enough, shows that this is the failing SQL:
Error Stack Dump
ORA-01403: no data found
Current SQL Statement for this session (sql_id=3n58uzvnuw2hj) -----
SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER = 'NLS_CHARACTERSET'
Under that, I get the call stack.
I ran this SQL manually and I get:
SQL> SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER = 'NLS_CHARACTERSET';
VALUE

Any ideas as to why I'm getting the ORA-01403 when I run expdp?
Thank you

Hello,
Your error looks like what is descibed into the Metalink Note 345198.1.
But this note apply to 10.1.0.4 not to 11.1.0.7.
So, you should open an issue to My Oracle Support.
Best regards,

Safe to run on 220 with a converter?

Hi Danno33614: A voltage converter isn't required. You will need a plug adapter only. The MacBook Pro power block is rated for up to 240V.
Hope this helps

Is microsoft Silverlight plug-in safe to run on OSX 10.7.5?

Is Microsoft Silverlight plug-in safe to run on OS X 10.7.5 ? Looking to stream download movies from Netflix

berdel,
For now, you will indeed need Silverlight for Netflix on your Mac. As rkaufmann87 suggested, you should always get any plugin directly from the manufacturer and keep it updated frequently for security reasons.
The good news is that Netflix is currently working on doing away with the Silverlight dependency. Within a few months we should all be able to cellebrate when Netflix releases a new version that uses modern HTML5 instead of Silverlight, and will run on all standards-complient browsers such as Safari, Chrome, and Firefox.

Database instance crashes when running expdp

Hi,
I have oracle 10.2.0.4 running on AIX.
when i try to run expdp as below...
expdp system/pwd directory=DATA_PUMP_DIR2 tables=TOAD_PLAN_TABLE dumpfile=test.dmp
i get an error as..
UDE-00008: operation generated ORACLE error 22303
OCI-22303: type "SYS"."KU$_STATUS1020" not found
and the database instance crashes.
I tried increasing the shared_memory_pool, checking the read, write permissions on the directory. but every single time i run the expdp, the instance crashes.
But when i try to run the exp for the same table, it runs fine.
Can someone help me resolve this so i can use the expdp feature.
Thanks.
Philip.

I could not find anything proper w.r.t the datapump failure.
is there a package or something i need to install in the database for the expdp to work.
or do i have to install any libraries for the datapump to work.
Thanks.

Safe To Run MacOSXUpd10.5.1.dmg?

Hi,
I upgraded my version of Leopard to 10.5.1 using the automatic Software Update mechanism. However, I read that it's a good idea to download the 109.2MB MacOSXUpd10.5.1.dmg file from Apple's website and run that. So my question is, is it safe to run that update when I'm already running 10.5.1?

Apple typically puts out two versions; a Delta, which takes you between a .1 and .2, or a .5 and .6 revision, and a Combo update, which takes you from .0 all the way to the latest, including the stops along the way--from 10.4.0 to 10.4.9 for example.
In this particular case, the difference is probably between PPC and Intel downloads using Software Update vs. both being included at the Support site.

Safe to run MBP without battery?

Hi, though I often like and am required to use my MBP without it's battery, I currently am just running it plugged into the wall. Since I don't want unnecessarily run down my battery without having gotten any true use out of it, is it safe to run my MBP plugged into the outlet without it's battery (the chance of a power outage causing me to lose my lost data aside)?

In addition to the above posts, consider that not only would a power outage be a risk, but keep in mind the relative ease of disconnecting the MagSafe adapter.
Also, there is a continuous chemical reaction occurring in the battery. Lifespan of the Li-polymer battery in your MBP is 400-500 cycles or 3-4 years, _whichever comes first_. If you leave it on the shelf for 3 years, unused, it will be nearly dead, especially since Li-based batteries need to be used to maintain their charge.
See my tip for lots of details:

I misspoke (wrote). Actually the MBP lowers the processor speed when running without the battery.

Running reports stored in the database

Hi guys,
Is it possible to have Reports 6i produce reports that are
stored in the database? Looking at the documentation, it would
appear the report definition files (RDF) must be stored in the
filesystem. I don't really want to be handing out filesystem
access (managing and it) to people - is there a way around this?
Thanks,
denty.

Hi,
Would anyone have any recommendations regrading running reports based on the data stored in an oracle database. We will soon go live with a project using an oracle DB. We do not wish to run reports directly from the production DB as it will impact performance. Have you actually measured the impact? If not, you are just making assumptions that -- lacking any other informatin -- appear to be invalid.
Is there any recommended method/architecture for reporting suggested by oracle for this type of scenario?
You make it sound like some unusual scenario. What you've described so far (running reports against an OLTP database) is just bread and butter operations for Oracle.
One idea is too runs some scripts that will write the data to another database and from there we will runs out reporting queries. Are there any other potential solutions?
And how does reading the data to insert into some other database cause less contention than reading data for a report?

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.
