when I upload a new RPD file in obiee12c existing data model getting replaced, if I wanna see the datamodel for multiple applications how can I do it
An RPD upload does just that. It uploads an RPD. You work with multiple applications by having all those applications inside one RPD. Whether one source or 50 makes no difference at all to the RPD.
I am new on Minio and object based databases.
I know that there is S3 select API but I want to add a new row or update a specific row in CSV file in Minio without need to download it and upload again.
Is there any way to do it?
In another words, I want to use sql based statements(insert/update) on a file stored in Minio.
You can only change Databases with SQL, it can only Import and Export CSVs so that they are usable for the Database. The Answer for now would then be a no. The easiest way you could achieve editing this csv would be to write a Script which either:
Connects to the Database and Changes the File in the Databases
Directory.
Downloads the File to edit it locally and then upload it again.
My database files are corrupted somehow!!
I have got only the .ibd (eg: customers.ibd) files of the table names in the MySql data directory, there is no other file extension of the table is available (eg: .frm or .myd).
Is there any ways to recover the data of the database??
I have received a file named STP.dmp containing a database backup, which I have successfully restored into Oracle.
I have also received multiple additional .dmp files, named sequentially - eg. STP-DOCS01.dmp, STP-DOCS02.dmp - which I am expecting to contain image and document files (perhaps in blob data format, I don't know).
However, upon trying to restore this database, using the following command:
Impdp bkup_user/password directory=exp_table dumpfile=STP_DOCS01.DMP TABLE_EXISTS_ACTION=TRUNCATE
I get an error: cannot location master table within provided dump files. I get the same when I try to get the database schema. The third-party who provided the files swear that the DOCS backup completed correctly and that they've sent us all the files.
I've tried renaming the DOCS DMP files so the name is in line with the main database, in case they were part of the same database, but that didn't do anything. I'm completely out of ideas what else to try. Can anyone help
If the files are sequentially named it could mean that the person which have done the exports used parallelism and wrote to multiple files at once, this is why a single file doesn't have a complete part of the data, try importing using:
Impdp bkup_user/password directory=exp_table dumpfile=STP_DOCS%U.DMP TABLE_EXISTS_ACTION=TRUNCATE
I'm useing java to write some programe,
I need to insert some file into database such as ".mp3, .wav" files.
by the way how insert these file into oracle database?
Have you considered just storing the MP3 metadata and file location. I worked on a image server years ago and we attempted storing the images inside the database. It was much faster to just hand off the file location to the server service requesting it, then it would fetch the file. It is possible to load the mp3 binary file into a the database as a BLOB if you really want to.
