Use exp to verify database

I want to use exp to check my database. Can I export to /dev/null? The following command fails:
exp system/pword file=/dev/null full=y volsize=0 log=x.log
ORA: 00942: table or view does not exist
Thank you in advance,

I don't really know why you would want to do an export and throw away the dump file, but you can try something like:
#/bin/ksh
ORACLE_HOME=path/to/your/oracle/home;export ORACLE_HOME
ORACLE_SID=your_sid;export ORACLE_SID
NLS_LANG='AMERICAN_AMERICA.WE8ISO8859P1';export NLS_LANG
ORA_NLS32=$ORACLE_HOME/ocommon/nls/admin/data;export ORA_NLS32
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data;export ORA_NLS33
mknod ./pipeexp.dmp p
exp system/pword file=pipeexp.dmp full=y log=x.log &
grep FOO < pipeexp.dmp
waitThis will use a pipe as the output file, and the grep command as the pipe reader. You could probably use any unix command that takes input form the command line.
We typically use this to compress the export on the fly.

Hi Sa;
Does anyone have experience in using exp and imp utility on 11i apps database? Is there any special method to achieve this. You want to take exp imp for which issue?
I want to do a full export and do an import.Follow:

A verify database for the reports even if we have created it using business

Hi All
Just a quick question.
Do I need to do a verify database for the reports even if we have created it using business views?
I am asking this bcoz we have added some new elements with formulas and we don't see them in crystal reports.
Any ideas are welcome.
Thnaks in advance

Hi
Yes, you can do that to ensure that Crystal Report checks for the changes.

Use exp/imp to migrate a database

hi,
I want to migrate a database from window to hp unix,
Can I use the following way? thanks!
First,exp from windows:
1.exp the schema without data
2.exp the whole database with data
Second,imp to unix:
1.use dbca to create a database;
2.imp the schema
3 imp the data to all schema.

Yes. Just make sure that you do a binary file transfer between windows and unix system otherwise you will end up with a corrupted dump.
Even after transfer, just to make sure, you can have a trial import with indexfile and show options to check the integrity of the dump.
Probably you can merge steps 2 and 3 of import in 1 step.

Using exp dump file, how to know schema/tablespace/database/table....

Hi
I have export dump file. I don't have any information other then that about the dumpfile.
1. How do I know what version of exp was used(or database version)?
2. what does the exp contain, whether it is table/schema/tablespace/database level export?
3. Is it possible that I can used impdp command to export a file which was exported using "exp" command?

1. Sorry for my ignorance but in first case how do I know if i have to use "imp or impdp".
As discussed in the above mentioned thread strings might reveal something but not sure. Otherwise you can always confirm by trying to run it.
And assuming that if I imported the dump(using trial and error rule), how do I know what level of export was the dump file created... ie
how do I know the present object(object imported in target) was belonging to which tablespace and schema in source database(question 2 of "Sidhu")?
When you will import it back in a new database, everything will be same as the original database. All objects will belong to their respective tablespaces,schemas blah blah...(where they were in the original database).

Using exp/imp to clone a database from Solaris to NT

Hi All,
We have an 8.1.6 Oracle database in production under Sun Solaris.
We actually use this database to run Siebel CRM system.
We have a Windows NT server which we used as a QA system
for this application.
We have a daily full export of our production database on the
Sun machine. Now my manager wants to import this production
dmp file into this Win NT database on a weekly basis.
The goal here is to maintain the state of this NT database
as much functional and close to the production one as possible.
I would appreciate your help on this.
I have some other general question:
in which case can the Oracle imp utility be run in the
full=y mode ?
does this make any sense at all ?
since the Oracle import utility does not delete
any existing objects before it imports, these objects
should be deleted manually and that's what I do
with all Siebel users schemas; of course I do not
do this with SYS, SYSTEM and other special Oracle
users; question: are there any objects in these
special Oracle schemas that have to be carried over from
the source database to the target database to
make the rest of the schemas functional ?
Somehow I failed to find Oracle documentation on how
to use exp/imp to create a complete clone of an Oracle
database.
Can direct path be used with full=y export/import mode ?
Thank you in advance,
Yuriy.

As an alternative to using daily/weekly exports and imports, what would probably be more effective here would be replication. The databases could synch on a nightly basis and updated tables and rows will be transferred from your OLTP system to your read-only system. More information can be found on replication from "Oracle8i DBA Handbook" by Kevin Loney and Marlene Therialt.

Database Table cannot be found when Verify Database

Post Author: brentlaw
CA Forum: Other
I have been using CRW 7 for many years. I recently upgraded to XI (I have current version). I can open existing reports and create new reports fine. The problem is when I Verify Database I get an error message "The Database table <tablename here> cannot be found. Remove this table from the report".
This happens to all existing and new created reports. The data fills correctly when previewing. The problem only occurs when Verifying Database.
I thought it might be an ODBC driver problem so I upgraded my driver to v 3.525.1117. At least I think I upgraded it I did not check the version before I installed SQL 2005 SP2. After installing SP2 it seemed to be fine but a week later the problem came back. Mysterious eh?
I am trying to launch a report from VB6 using RDC and rpt file. I get logged in correctly but at .viewreport I get a generic error message. I am assuming the problem is related the the issue I raise in this forum post.

Post Author: brentlaw
CA Forum: Other
I fixed the problem. In CR XI Developer Designer window I opened up Database-SetDataSourceLocation. I noticed that in "Properties" the last item "Use DSN Default Properties": was set to True. I changed this value to False. Now this problem is solved.
I am Not using Windows Authentication I am using SQLServer authentication. In my code I was passing SQLServer Authentication credentials.
I opened up all of my CR 7 reports in CR XI and changed this setting on both the Main and the Subreort property in the SetDataSourceLocation dialog box and now all my reports work. I am a happy camper.
I don't know if this is a CR 7 conversion to CR XI only situation or not. Hope this information helps someone else.

Using Data Pump when database is read-only

Hello
I used flashback and returned my database to the past time then I opened the database read only
then I wanted use data pump(expdp) for exporting a schema but I encounter this error
ORA-31626: job does not exist
ORA-31633: unable to create master table "SYS.SYS_EXPORT_SCHEMA_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 863
ORA-16000: database open for read-only access
but I could by exp, export that schema
My question is that , don't I can use Data Pump while database is read only ? or do you know any resolution for the issue ?
thanks

You need to use NETWORK_LINK, so the required tables are created in a read/write database and the data is read from the read only database using a database link:
SYSTEM@db_rw> create database link db_r_only
2 connect to system identified by oracle using 'db_r_only';
$ expdp system/oracle@db_rw network_link=db_r_only directory=data_pump_dir schemas=scott dumpfile=scott.dmpbut I tried it with 10.2.0.4 and found and error:

I found in Metalink the bug 7331929 which is solved in 11.2! I haven't tested this procedure with prior versions or with 11g so I don't know if this bug only affects to 10.2.0.4 or 10* and 11.1*

[Forum FAQ] How do i use xml stored in database as dataset in SQL Server Reporting Services?

Introduction
There is a scenario that users want to create SSRS report, the xml used to retrieve data for the report is stored in table of database. Since the data source is not of XML type, when we create data source for the report, we could not select XML as Data Source
type. Is there a way that we can create a dataset that is based on data of XML type, and retrieve report data from the dataset?
Solution
In this article, I will demonstrate how to use xml stored in database as dataset in SSRS reports.
Supposing the original xml stored in database is like below:
<Customers>
<Customer ID="11">
<FirstName>Bobby</FirstName>
<LastName>Moore</LastName>
</Customer>
<Customer ID="20">
<FirstName>Crystal</FirstName>
<LastName>Hu</LastName>
</Customer>
</Customers>
Now we can create an SSRS report and use the data of xml type as dataset by following steps:
In database, create a stored procedure to retrieve the data for the report in SQL Server Management Studio (SSMS) with the following query:
CREATE PROCEDURE xml_report
AS
DECLARE @xmlDoc XML;
SELECT @xmlDoc = xmlVal FROM xmlTbl WHERE id=1;
SELECT T.c.value('(@ID)','int') AS ID,
T.c.value('(FirstName[1])','varchar(99)') AS firstName,
T.c.value('(LastName[1])','varchar(99)') AS lastName
FROM
@xmlDoc.nodes('/Customers/Customer') T(c)
GO
P.S. This is an example for a given structured XML, to retrieve node values from different structured XMLs, you can reference here.
Click Start, point to All Programs, point to Microsoft SQL Server, and then click Business Intelligence Development Studio (BIDS) OR SQL Server Data Tools (SSDT). If this is the first time we have opened SQL Server Data Tools, click Business Intelligence
Settings for the default environment settings.
On the File menu, point to New, and then click Project.
In the Project Types list, click Business Intelligence Projects.
In the Templates list, click Report Server Project.
In Name, type project name.
Click OK to create the project.
In Solution Explorer, right-click Reports, point to Add, and click New Item.
In the Add New Item dialog box, under Templates, click Report.
In Name, type report name and then click Add.
In the Report Data pane, right-click Data Sources and click Add Data Source.
For an embedded data source, verify that Embedded connection is selected. From the Type drop-down list, select a data source type; for example, Microsoft SQL Server or OLE DB. Type the connection string directly or click Edit to open the Connection Properties
dialog box and select Server name and database name from the drop down list.
For a shared data source, verify that Use shared data source reference is selected, then select a data source from the drop down list.
Right-click DataSets and click Add Dataset, type a name for the dataset or accept the default name, then check Use a dataset embedded in my report. Select the name of an existing Data source from drop down list. Set Query type to StoredProcedure, then select
xml_report from drop down list.
In the Toolbox, click Table, and then click on the design surface.
In the Report Data pane, expand the dataset we created above to display the fields.
Drag the fields from the dataset to the cells of the table.

I have near about 30 matrics. so I need a paging. I did every thing as per this post and it really works for me.
I have total four columns. On one page it should show three and the remaining one will be moved to next page.
Problem occurs when in my first row i have 3 columns and in next page if I have one columns then it show proper on first page but on second page also it gives me three columns insted of one. the first column data is exactly what I have but in remaining two
columns it shows some garbage data.
I have data like below.
Metric ColumnNo RowNo
1 1
1
2 2
1
3 3
1
4 1
2
so while grouping i have a row parent group on RowNo and Column group on ColumnNo.
can anyone please advice on this.

Implement row-level security using Oracleu2019s Virtual Private Databases (VPD)

Environment: Business Objects XI R2; Oracle 10g
Functional Requirement:
Implement row-level security using Oracleu2019s Virtual Private Databases (VPD) technology. The restriction is that the Business Objects Universe connection should use a generic/u201Capplicationu201D database user account. This will allow the organization to avoid the situation where the Business Objects password and the Oracle password need to be kept in synch.
What do we need from the Business Objects support team?
1.     Review the 2 attempted solutions that we have tried to implement
2.     Propose solutions/answers to open questions for each of the attempted solutions
3.     Propose any alternate solution that will help us implement the Function Requirement stated above
Attempted Solution 1: Connection String uses Oracle Proxy User
The connection string that is specified in the Universe is the following:
app_user[end_user]/app_user_pwdarrobaDatabase.WORLD
app_user = generic application user
end_user = the oracle account of the end user which is set using arrobaVariable('BOUSER') app_user_pwd = password of the generic application user
We have tried and implemented this in our test environment. However, we have some questions and concerns around how the connections are reused in a connection pool environment.
Open Question for Solution 1:
i. What happens when multiple proxy users try to connect on at the same time? Business Objects shares the generic app_user connect string. However, every user that logs on will have their own unique proxy user credentials. Will there be any contention involved? If so, what kind of errors can we expect?
ii. If a user logs on using his credentials (proxy user), and business objects opens up a connection to the database using that user's credentials (as the proxy user but logging in through the generic app user). Then the user exits out --> based on our test today, it seems like the database connection remains open. In that case, if another user logs on similarly with their credentials, will business objects simply assign the first users connection to that second user? If so, then our security will not work. Is there a way that Business Objects can somehow ensure that everytime we close a report, the connection is also terminated both at the BO and DB levels?
iii. Our 3rd question is general high level -> How connection pooling works in general and how it is implemented in BO, i.e. how are new connections assigned, how are they recycled, how are they closed, etc.
Attempted Solution 2: Using the ConnectInit parameter
Reading through a couple of the Business Objects documents, it states that u201CUsing the ConnectInit parameter it is possible to send commands to the database when opening the session which can be used to set database specific parameters used for optimization.u201D
Therefore, we tried to set the parameter in the Universe using several different options:
ConnectInit = BEGIN SYSTEM.prc_logon('arrobaVARIABLE('BOUSER')'); COMMIT; END; ConnectInit = BEGIN DBMS_SESSION.SET_IDENTIFIER('arrobaVariable('BOUSER')'); COMMIT; END;
Neither of the above iterations or any variation of that seemed to work. It seems that the variable is not being set or being u201Cexecutedu201D on the database.
One of the Business Objects documents had stated that Patch ID 38, 977, 350 must be installed in our BO environments. We have verified that this patch has been applied on our system.
Open Questions for Solution 2:
How do we get the parameter ConnectInit to work? i.e. what is the proper syntax to enter and what other things do we need to check to get this to work.
Note: Arroba word is being used instead of the symbol in order to avoid following error message:
We are sorry but your message can not be posted since you have included an email address. Please remove the email address and re-post.

the connectinit setting should look something like this:
declare a date; begin vpd_setup('@VARIABLE('BOUSER')'); Commit; end;
The vpd_setup procedure (in Oracle) should look like this:
CREATE OR REPLACE procedure vpd_setup (p_user varchar)IS
BEGIN
DBMS_SESSION.set_vpd( 'SESSION_VALUES', 'USERID', p_user );
END vpd_setup;
Then you can retrieve the value of the context variable in your vpd functions
and set the vpd.

How to reflect db changes - Verify Database doesn't seem to work

I have changed a database (MS SQL Server) column from varchar 255 to varchar 1000, but the designer doesn't pick up the change.
I read that db changes can be picked up by using 'Verify Database' feature. It doesn't seem to work for us though. Is there any configuration to turn on for the feature to work properly or any work-around to refresh the database changes?
We are making the database connection using JDBC (JNDI) option since the report is being used in a Java web application.
Any comments or insights will be very much appreciated!

Hi Wallie,
Thank you very much for your reply! Here are the answers to your questions.
Are you able to create a new report off the modified database?
==> Yes.
Do new reports see the changes made to the database?
==> No.
Are the reports connecting directly to the database table, or is it a stored procedure, business view, universe being used?
==> Through a business view.
By the way, after trying so many things, I was able to figure out the reason. Since the report is using a view, not directly the table, the view itself had to be recompiled to reflect the table changes so that the view could pass the changes to the report. It was a very good thing to know. Your last question could have been a very helpful insight for this issue! Thank you so much again!
