Find exact time a database was recovered to

Oracle 11gR1
How can I find out the exact time a database was recovered to, assuming I do not know what value was used in the "SET UNTIL TIME" clause?

>Will the resetlogs time show the time I issued the "alter database open resetlogs" command at or will it show the time that the database was actually recovered to
The RESETLOGS_TIME in V$DATABASE shows when the ALTER DATABASE OPEN RESETLOGS was issued.
It does NOT show the time the database was recovered to.
Thus, today, 14-Jun I restore a database backup of 11-Jun and do an Incomplete Recovery to 12-Jun. My SET UNTIL TIME was 12-Jun.
V$DATABASE.RESETLOGS_TIME shows 14-Jun.
The only way to know the time the database was recovered to is to query a table which you know holds transaction timestamps and would have had a transactions just at or before the SET UNTIL TIME. (e.g. an audit table ?)

What is the exact difference between Database Cloning and Database Refresh?

Hi,
Can anybody tel me the exact difference between Database Cloning and Database Refresh?
I Have some conflicts in these topics.
Thanks
Rajesh

Refresh is what it says, "refresh" . You have a main site which would always have the data being inserted into it. There would be another site which would remain some where else . This site needs to be refreshed with the primary site. So you need to do export from the primary, push it to the secondary site and done!

Exact copy of database

Our management want to set a server with production database to be copied there as exact copy of the
production database running (as like mirror image). I mean we need to install all objects incluidng users ,triggers, schemas etc. to the new server for training. How could attain it . Please give the details steps. We dont want to
make more configurations and blop blop..... . Just we need a miiror image of production database.

Best way to clone a production database is RMAN duplication. Read the link.

Also, if your database size is small like 200 GB then you can go for data pump if your oracle database version is 10g. On 9i you can do export/import but this will be time consuming for 200GB or more.

What exactly are Logical Database in Programs?

Hi Experts,
While digging deep into the programs, using the T-Code SE93/SE38, we come across Logical Database.
what is the functionality and use of this Logical Database?
Best Regards,

Normally moderators reject unresearched questions, but this one has not been discussed much for it's security aspects.
In the ABAP forums you will find a lot of discussions about LDB's ("LDB" is your search term).
Please do a search and reconsider and focus your question more.
What is it about LDB's that you would like to discuss?

Get exact row from database table

This is part of my source code that displays one row from getQuest recordset. Always first.
<body>
<?php echo $row_getQuest['content']; ?>
: <?php echo $row_getQuest['prom1']; ?>
<?php echo $row_getQuest['prom2']; ?>
<?php echo $row_getQuest['dos1']; ?>(); <?php echo $row_getQuest['dos2']; ?> (); <?php echo $row_getQuest['dos3']; ?> (); <?php echo $row_getQuest['dos4']; ?>(); <?php echo $row_getQuest['dos5']; ?> (); <?php echo $row_getQuest['dos6']; ?> (); <?php echo $row_getQuest['dos7']; ?> ().
</body>
Can i change it so, that on this page it always displayed row with exact position in the table - for example second or 15th - independently of row contents and rows deletition, moving or changing in table?

But if I add 5 rows to table, then delete all of them and add 5 again - auto incremented id will 6 for first in table and 10 for last. If i delete all and add 5 again it will be 11...15 and so on. As I said - I cannot rely on row contens - because I'm planning to delete and add data from that table frequently. Or other solution could be to allways keep id from 1 to [amount of rows]. I do not know how this is done.
Or am I wrong about id?

After upgrading to Yosemite (I don't have iPhoto anymore, only PHOTOS) my pictures will not import from my iPad or iPhone 5s or any picture from web, it shows "Database Error: failured to persist version"

After upgrading to Yosemite (I don't have iPhoto anymore, only PHOTOS) my pictures will not import from my iPad or iPhone 5s or any picture from web, it shows "Database Error: failured to persist version". Any help will be greatly appreciated.

Sorry,
Yes, the error message is exactly like that ("Database error: failured to persist version")
No photos will import at all. I use USB to import from iPhone 5s or iPad 2.
About the difference? iPhoto and Photos . Are there two softwares?
I also will like to merge and/or synchronize all my photos I had saved to iCloud backups, Macbook Pro, iPhone 5s and iPad hard drives using iPhoto. It's call iPhoto library. At one point I turned off streaming.
Thanks again Larry HN.

Deleting a single row from a dataTable / database

Hi,
I am fairly new to JSF so please bear with me if the answer is obvious :D. I'm using a dataTable component to display data from a database and would like to add a commandLink component to every row in the table that deletes that row from the database. What is the most effective way of doing this?
I'm thinking of using a ListDataModel with some function that removes the correct row (though I'm not sure how it will tie in with a commandLink and exactly where the database will be updated). I'll appreciate any pointers or perhaps even an online example of something similar.
Alternatively I suppose you could pass an "id" parameter on with the commandLink that somehow gets read in the request and the appropriate row is removed accordingly. This solution seems cumbersome however.

This solution seems cumbersome however.Yes, your instincts are correct there. Binding the data model to a backing bean to get the UIData instance for the table. Then use UIData.getRowData() to get the object corresponding to the row containing the link/button. Then execute your business logic to delete the row from the database. Then you need to ensure the data model is updated to reflect the new state of the database.

What would cause difference in the data of a Citadel database in 1 process?

The on Columbus Day weekend the laptop I have been using to run my LabVIEW DSC program completely froze and the only way to recover on Wednesday was to do a hard boot. After the computer rebooted, I checked to find out when the PC crashed. My first thought was to look at the database to see when the data flow stopped. Unfortunately, It was not completely clear the exact time the database stop receiving updates. The time range of when data stopped was about 40 minutes. Meaning one of my shared variables,flow, showed no data at 4:40 and another shared variable, temperature went on until 5:20 then stopped. Why would this happen? How can I prevent this?

Hi Dan!
Thank you for contacting National Instruments. From what you have mentioned, it looks like you are on the right track in that you should monitor the serial timeout from within a While Loop. Also, I would try running this program in Highlight Execution in order to determine if the problem is occurring from the serial connection portion of the block diagram. Any information you might run across when you are able to access the program could be helpful in locating the problem. I hope this helps! Let us know if you find any additional information or have any other questions. Have a great day!

Logical Standby databases

Hi,
When we say "Logical Standby Databases are logically identical to primary databases although the physical organization and structure of the data can be different." what does it exactly means?
Does it mean that in logical standby tablespace name, schema name, table name, column names etc can be different and still has the same data as primary?
Does it mean that we can exclude indexes and constraints as present in primary?
Only the data should match with primary word by word, value by value?
I am asking this as i have never worked in a logical standby database but i seriously want to know.
Please answer.
Regards,
SID

Physical standby differs from logical standby:
Physical standby schema matches exactly the source database.
Archived redo logs and FTP'ed directly to the standby database which is always running in "recover" mode. Upon arrival, the archived redo logs are applied directly to the standby database.
Logical standby is different from physical standby:
Logical standby database does not have to match the schema structure of the source database.
Logical standby uses LogMiner techniques to transform the archived redo logs into native DML statements (insert, update, delete). This DML is transported and applied to the standby database.
Logical standby tables can be open for SQL queries (read only), and all other standby tables can be open for updates.
Logical standby database can have additional materialized views and indexes added for faster performance.
Installing Physical standbys offers these benefits:
An identical physical copy of the primary database
Disaster recovery and high availability
High Data protection
Reduction in primary database workload
Performance Faster
Installing Logical standbys offer:
Simultaneous use for reporting, summations and queries
Efficient use of standby hardware resources
Reduction in primary database workload
Some limitations on the use of certain datatypes

Location of UWL data in the database

Hi,
where exactly in the database does the data of UWLs get stored (table)?
I guess I could figure it out by entering some data into a UWL and then searching in the database, but I have some infrastructural problems here.
Thanks,
Ingmar

Hi,
I want to know the same thing.
Please tell me if you have figured out the exact table in the backend.

Doc ID: Note:10767.1
Subject: How to perform FULL System Export/Imports
Type: BULLETIN
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 18-APR-1994
Last Revision Date: 30-AUG-2002
Purpose
This article highlights some important points to consider when performing
a Full System Export and Import.
Scope and Application
It is intended to assist users performing FULL System Exports and Imports.
A Full System Export and Import is a useful way to replicate or clean up
a database. Please note the following guidelines when performing a Full
System Export and Import:
1. When performing the import, ensure you are pointing at the correct
instance. Always check values for the SID and two task driver before
proceeding.
*Note: On Unix systems, just entering a sub-shell, such as using
C-shell, can change the database that the import would work
against.
2. When possible, it is advisable to take a physical copy of the
exported database and the database you intend to import into before
starting the import. This ensures any mistakes are reversible.
3. NEVER run a FULL SYSTEM IMPORT on a machine that has more than one
database UNLESS you are 100% sure all tablespaces have been
pre-created. A full import will create any undefined tablespaces
using the same datafile names as the exported database. There are
situations where this is very dangerous:
-> If the datafiles belong to ANY other database, they will be
CORRUPTED. This is especially true if the exported database is
on the same machine, because its datafiles will be re-used by
the database you are importing into.
-> If the datafiles have names that clash with existing operating
system files.
4. When exporting, it is advisable to also produce a report showing
information you may need before / after the import:
-> List the tablespaces and datafiles
-> List the rollback segments
-> List a count, by user, of each object type such as tables,
indexes, etc.
This enables you to ensure that tablespaces have been pre-created
and to check the success of the import after it is complete.
5. If you are creating a completely new database from an export, remember
to create an extra rollback segment in SYSTEM, and make this available
in the init.ora file before proceeding with the import.
6. There are some versions of export that do not retain sequence numbers
correctly. It is advisable to select next_value for each sequence
after the export so that these can be checked after import.
Following these guidelines will help you to avoid major problems.

Subject: How To Copy an Oracle Database To Another Machine
Type: HOWTO
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 12-OCT-2001
Last Revision Date: 01-OCT-2003
goal: How to copy an Oracle database to another machine
fact: Oracle Server - Enterprise Edition
fix:
Pre-requisites: The copy is between 2 machines, both have to be on the same OS
and have to have exactly the same database version installed.
1. Make sure the database you want to copy was closed with a SHUTDOWN IMMEDIATE,
SHUTDOWN NORMAL or SHUTDOWN TRANSACTIONAL.
2. Copy init.ora and control files to create instance and be able to go in
mount mode. Check the init.ora for the locations where the controlfiles have
to be, if those locations are not valid on the machine put the control files on
different places and adjust the init.ora accordingly.
3.a. Copy the datafiles (all of them).
b. Copy the redo-logfiles (all of them).
4.a. (Unix only) Set the environment variables:
ORACLE_SID - set to the database name you wish to create
ORACLE_HOME - set to full pathname of the Oracle system home directory
PATH - needs to include $ORACLE_HOME/bin
b. (NT/2000 only) Do 'set ORACLE_SID=<SID>'
Use oradim to create the service for the instance. For more information
on oradim please refer to (the part that refers to creating a new instance):
Note:68720.1 Creating a new 7.3, 8.0, 8.1 Instance/Database
5. Use servermanager (check the name to use for your version of oracle) or
sqlplus (version 9i and above) to startup the database in mount mode.
Do
CONNECT INTERNAL/<PASSWORD>
then
STARTUP MOUNT
Then do a rename of the copied datafiles if they are not in the same path as on
the other machine. For all the files that are in the result of the query:
SELECT NAME FROM V$DATAFILE;
do
ALTER DATABASE RENAME FILE '<oldfullpath>\<filename>' to <
newfullpath>\<filename>';
6. Query the datadictionary for the old location of the redolog files using:
SELECT MEMBER FROM V$LOGFILE;
If the new place is not the same as the old do:
ALTER DATABASE RENAME FILE '<oldfullpath>\<redologfilename>' to &
lt;newfullpath>\<redologfilename>';
7. Now open the database:
ALTER DATBASE OPEN;

About database link

i am able to access a database link from development database .But i am not able to access that same database link
from test database. is it firewall issue or do i need any grants ?
Thank you in advance ..

Hi,
A database link works only within the database in which it was created.
If you want to query Production tables from inside the Test database, then you must create a database link in the Test database.
It doesn't matter if you already ave a link in the Development database that lets you query Production. You might be able to re-use the exact same CREATE DATABASE LINK command in Test, but you can't use the Development-to-Poroduction link in Test.
There may be firewall or permission problems, also.

Create a copy of active database using T-SQL.

I have a requirement to create a copy of existing active (currently in use) database through code.
I need to copy all objects which include tables, stored procs, triggers, functions, foreign keys, constraints, primary keys, etc... from source DB to new DB.
Both databases can be in different servers where I have access to both the servers. I also need to copy data for some tables....
It is exactly what copy database wizard is doing... but I want to do it through T-SQL code.....
is it possible?

This doesn't sound like too easy task. I tried to search, but the best I found so far was Freeware SQL Script Generate utility
I do have a blog to generate all stored procedures
How to script all stored procedures in a database
but this is only a small part of the task. Brad Schulz has a blog to generate table creation/insert statements. I don't remember seeing the complete free T-SQL solution for all SQL Server database objects.
