Best approach for copying DB from one system to another

I have Oracle 9i Enterprise running on a UNIX box with a large database upon it (well, 3 - 2 test databases).
I want to recreate one of the databases in Personal Oracle on a Windows machine, again 9i.
I have managed to export the database into DMP files which I ZIPped up to keep them small.
I have also managed to install Oracle 9i Personal edition on the Windows machine.
But how do I import the data? I mean, do I have to recreate the database, tablespaces, etc exactly, can this be done by extracting the scemea and making a script? There must be a "recommended" path!
Many thanks

I would not use
Full=Y
in this case, you have different edition of Oracle on different platform.
It will be better to identify your previous schema holder and use
fromuser=old_schema_user touser=new_schema_user
approach

Copy Screen from one system to another

Hi,
My development system has been upgraded to ECC 6.0 from 4.7 . Now some of the standard screens are missing in ECC 6.0. Now I need to copy the missing screens from the quality system which is still in 4.7 to the upgraded ECC 6.0 development system. Is there any method?.
I tried to use Download/Upload method.I am able to download the screen from quality but i am not able to upload it into the development as 'Upload' option is greyed out in development.
Thanks & Regards,
Soumya.

Hi,
Note: This method is useful for Z-screens only.
Execute SE51 T-code>enter your module pool program name&screen number>click on change push button>Go to Layout by click on Layout push button>then choose path in menu bar like as Utilities>upload/down load>download. So you can down load from source system. next follow same steps in your destination system use upload instead of download.

How to copy mailstore from one system to another ? is nfs possible?

hello we want to copy the mailstore which is /global/mailstore/opt/SUNWmsgsr/data to a new system. we try to mount this directory with nfs in the new system in order to make a copy but i have read that nfs may cause data corruption and lose data, mails.
is it still the case. the current messaging server is
Sun Java(tm) System Messaging Server 6.2-8.04 (built Feb 28 2007)
libimta.so 6.2-8.04 (built 19:28:07, Feb 28 2007)
SunOS jesmail 5.9 Generic_118558-21 sun4u sparc SUNW,Sun-Fire-V440
the mailstore will be moved for a migration. the new system is;
Sun Java(tm) System Messaging Server 6.3-6.03 (built Mar 14 2008; 32bit)
libimta.so 6.3-6.03 (built 17:07:13, Mar 14 2008; 32bit)
SunOS messaging1 5.10 Generic_137112-02 i86pc i386 i86pc

but have no access to it? (cd, ls,) give permission denied and the owner of directory is 60002. i checked in the /etc/passwd and it corresponds to user noaccess. is this behaviour due that i try to mount the message store in another system while the "old" messaging server is running?Make sure that the mailsrv user (/etc/passwd) and mail group (/etc/group) entries on both systems are identical, i.e. their ID's must match otherwise the NFS can re-map the files to the 'nobody' user. You will need to remount the directory after making any changes to the user/group files.
i have mounted another dircetory outside the mailstore with the same settings (read-only) and it works correctly it is mounted read only and i can cd to it and list the contents.This is probably because the directory was owned by a user that existed on both systems with the same ID e.g. the root user.

Looking for best design approach for moving data from one db to another.

We have a very simple requirement to keep 2 tables synched up that live in 2 different databases. There can be up to 20K rows of data we need to synch up (nightly).
The current design:
BPEL process queries Source DB, puts results into memory and inserts into Target DB. Out of memory exception occurs. (no surprise).
I am proposing a design change to get the data in 1000 row chunks, something like this:
1. Get next 1000 records from Source DB. (managed through query)
2. Put into memory (OR save to file).
3. Read from memory (OR from a file).
4. Save into Target DB.
Question is:
1 Is this a good approach and if so, does SOA have any built in mechanisms to handle this? I would think so since I believe this is a common problem - we don't want to reinvent the wheel.
2. Is it better to put records into memory or writing to a file before inserting into the Target DB?
The implementation team told me this would have to be done with Java code, but I would think this would be out of the box functionality. Is that correct?
I am a SOA newby, so please let me know if there is a better approach.
Thank you very much for your valued input.
wildeman

Hi,
After going through your question, the first thing that came to my mind is what would be the size of the 20K records.
If this is going to be huge then even the 1000 row logic might take significant time to do the transfer. And I think even writing it to a file will not be efficient enough.
If the size is not huge then probably your solution might work. But I think you will need to decide on the chunk size based on how well your BPEL process will work. Possible you can try different size and test the performance to arrive at an optimal value.
But in case the size is going to be huge, then you might want to consider using ETL implementations. Oracle ODI does provide such features out of the box with high performance.
On the other hand, implementing the logic using the DBAdapter should be more efficient than java code.
Hope this helps. Please do share your thoughts/suggestions.
Thanks,
Patrick

Best method for transferring data from one database to another?

There is an 8i database I have to deal with on a regular basis. Besides being completely outdated and unsupported, in my opinion the database has not been well-maintained--for a table with 25 million records, should ‘select count(*) from table;’ take 5 minutes to run? I don’t really know, but that seems long to me. Many complex queries (most including only tables with less than a million records) take a ridiculously long time to run, to the point that I can’t even run some of them.
I am not the DBA; I don't have the authority to fiddle with the database (nor would I feel comfortable doing that), and the powers that be will not put effort into improving functionality of this database due to an alleged plan to update/replace it within the next year. However, in the mean time, I still have to get data out of this database on a regular basis.
I have XE 10g installed on my local machine, and I have set up a database link in it to the 8i database. I have found that I can pull in basic data (simple queries) from the 8i database into tables in my XE database (e.g. create table tbl1 as select data from tbl1@8idb) and then query those tables to get the information I need much, much faster (including creation of the tables). While this option does not allow me to create queries/reports that other people can run, it makes work I’m doing only for myself much faster.
What I’m wondering is, what is the best way to bring the information I need over to my database? I usually don’t need entire tables, and I can probably identify a number of key tables (or parts of tables) I need. What I’ve been doing up until now is writing CREATE TABLE statements on the fly, but then I end up forgetting what all I’ve done, and each time I want up-to-date data, I have to drop the tables and re-create them. It seems to me that there should be an easier way to do this than to copy and paste from a text document into SQL*Plus.
Does anyone have any suggestions for me on how best to do this?

Sorry, I guess I posted this in the wrong forum. I re-posted in the database-general forum.

Copy query from one system to another one

Hi experts,
We have two BI systems. I need to recreate all the queries from the first system. I am exploring options if there is a way to copy the queries from the first to the second. Anone experienced with this?

Hi Kumar,
for the same landscape as you know the normal Transport strategy,
if You are looking to migrate the Queries to Different BW Landscape, :
Before Migrating the Queries need to make sure that all the InfoObjects, DataFlow should be available in the same version and in the same condition in the Target BW system; then only think to move the Queries
Connecting the 2 BW systems through RFC is BASIS Job,
as a BI Consultant first analyze the both source and Target Systems in the sence of DataFlow, all the Objects, DataSources etc... and make sure to maintain same in both systems, if required need to move the Dataflows also before the Queries.
Note: if you move the Dataflow to target system the existing objects in the Target system will be overwrite, so first study the two systems and prepare a documnet with all concerns.
Hope this helps you

How can we copy FSV from one system to another system

Hi Gurus,
I was created FSV in sand box, i want to creat same in Dev system also
like this i have to create 5 fsv s in dev system which already created in sandbox
is there any way to copy from sandbox to Devsystem
Kindly guide me on this
Thanks in advance
Kumar

You don't mention which operating system you have so it's difficult to provide an answer since the mac and Windows stores the files differently.
The other thing you can do is just re-download the apps from the iTunes Store. Just login to the iTunes Store on the other computer using the same Apple ID. On the right-hand side of the iTunes Store page you will see a 'Purchased' link. Clicking on that will take you to a page that will list your past purchases which you can re-download to the new computer.

Transfer of workflow from one system to another

Hi all,
I have a requirement as follows:
1) V have developed a workflow in our system and tested
2) now the client wants tht in their system
if it is within our system, v can transport the request to copy tht workflow. But here the system itself is a new one where we need to do all configurations for workflow development. There is a way of storing the workflow as XML and thn importing it into the system.
Can anyone suggest with solution for this transfer from one system to another?
Thanks,
Sivagami

Hi,
1) In the T.code SWDD, Give your Workflow no. and Press enter.
2) Goto Menu, in the first Menu you can find Export and Import.
3) You have to export and save that XML file
4) Then go to the new system in the SWDD, Click import and it will ask of the file, upload the same file which you export from that system

How to copy documents for InfoProvider data from one cube to another cube

Hello Everyone,
We are using standard document feature to store document/comment about the data shown in the report/planning query. Relevant characteristics have the property 'characteristics is document attrib' turned on/selected for this purpose.
Looks like the documents created gets tagged to a particular InfoProvider along with characteristic value assignment.
Is there a way to move or copy documents from one InfoProvider to another InfoProvider.
As per the design requirement, we need to move data from a real time InfoProvider (transaction cube) to a basic reporting cube. The data in the first/source cube stays for a period of approx 3 months before moved to other cube. We want the documents associated with InfoProvider data also to be moved, so that users can continue to see the document/comments what they had created earlier.
I looked at the Documents tab in DataWarehouse workbench. No options seem to be available to copy or move documents.
Any help will be highly appreciated and points will be rewarded accordingly!
Best regards,
Sanjeeb

Hi
Have you got any answer to this? I would also be interested in a copy function but more from one query ID to another.
Kind regards,
Daniel Müller

How to copy a table from one system to another system

Hi all,
can any one say how to copy table from one system(sys1) to another system(sys2).
regards,
nagaraj

There are many ways.
1. Use the already existing transaport request number for that table to do the transaport (Active)
2. Create mannual transport request from SE01 and in the object list enter following
R3TR -- TABI -- <Table Name>
And do the transaport.
3. Ask your basis consultant to do the transaport from oracle layer.
Thanks,

How to copy WorkFlow from one system to anorther system

Hi All,
I have to Copy the Work Flow from One system to another system. So how to download and upload workflow from SAP. Please help me in this regard.
Thanks,
Ananth

Hi Ananth,
Yes it is. From the workflow builder menu, choose Workflow > Import/Export and export to an XML file.
You can also import from an XML file into a different system in which case the builder will create a new
workflow in a 'New, Not Saved' status. Then when you save it, it will assign the unique IDs for the workflow and each task.
You might also consider getting the program logic for any custom business objects. You can do this by going to the basic data of the business object and doubleclick the program name. From here, you can choose download from the utilities menu to get the program which includes the custom methods, attributes, etc.

How do I reorganize my photos on iPad 2? I need to move (not copy) photos from one album to another. When I use the copy function to another album, and then try to delete an image from the original album, the system wants to delete the photos from all a

How do I reorganize my photos on iPad 2? I need to move (not copy) photos from one album to another. When I use the copy function to another album, and then try to delete an image from the original album, the system wants to delete the photos from all albums. Please help.

You can't do it directly on the iPad - the new album functionality basically only allows you to copy photos into those new albums, you can't move them. The way that I think of it as working is that you are just creating pointers to the photos in those new albums, so if you then delete the original photo on the iPad you therefore automatically delete all the pointers to it.
If you want to re-organise your albums then you will need to do it on your computer and then sync those albums over to the iPad
