Can I safely delete staging tables after the migration?
I followed this link and finished migration from SQL Server to Oracle.http://www.Oracle.com/technology/OBE/hol08/sqldev_migration/MSSQLServer/migrate_microsoft_sqlserver_otn.htm
Now, I have a user "mwrep" and "mwrep_orcl" connection When I develop in this regard, I noticed that there are a lot of tables with name starting with "MD". In addition to those, there are some starting with "Outphasing".
Given that the imported tables are schema 'mwrep' and I want to continue to use that user as my user development. Can I remove these tables that I mentioned above? Thank you!
MD_ tables that you see are part of the migration repository. Migration repository is used for capturing migration related third party processing database meta information. Once you are convinced that the migration has completed successfully, you can use the command "Delete repository Migration" to get rid of the migration repository tables. You can do a right click on the oracle connection that actually hosts the repository and choose the menu 'Remove the Migration repository' get rid the repository tables. In a nutshell, the answer is Yes, you can delete the migration repository and the objects associated with them have a negative impact on the migrated objects db and the clean is to do it by selecting the menu item "delete the Migration repository.

Can I safely delete "Windows.old" after a successful relocation?
I caught a virus and had to reinstall Windows. The repair disk intalled a new version clean and left in a folder on my hard drive. I moved all of the things I've wanted on an external drive, so I have nothing of it. Can I remove it to clear disk space?

Windows.Old contains all your old files of program, Windows, and personal spaces (C:\Users\your name\etc).
You can delete it (you need to maybe take possession of this first and reassign your rights to him). But like I said that it contains your old personal folders and office, you still have stuff in there you want.

Can I safely delete the D partition on the HARD drive?
Second question: my laptop came with the HD in two partitions, C and d is there a purpose for this and I can easily (safely) delete the D partition?
You can do what you want and you can create a partition but HARD DISK with two partitions has since. All important data, you can save the second one (D). If something is wrong with the operating system you can install it at any time on the partition c. on this way, all your data will still be there.
The delivered use recovery media, you can use the configuration option and select installation on already created the C partition.
I recommend you leave him with two partitions.

When I started using Lightroom, I installed it on my iMac - so I have the original and also Lightroom 2, 4 and 5 on this drive, and I always started Lightroom from the icon in the dock. For the past year or so I start and work from a copy on an external hard drive, so I think it's the current version of my catalogs.
Can I safely delete previous versions of Lightroom from my computer (I am currently free space).
Can I reinstall Lightroom software directly on the external drive and then even that remove it from the computer - because I assume that the external drive refers to the LR-5 on the computer in order to open?
Mac OSX 10.7.5

Hello
You can remove the old version of the Lightroom from your computer. Make sure that your catalog of work is safe.
You can directly install Lightroom on the external hard drive, but adobe does not recommend that.
Thank you

How to compare the length of the data to a staging table with the definition of the base table
Hello
I have two tables: staging of the table and the base table.
I get flatfiles data in the staging of the table, depending on the structure of the requirement of staging of the table and the base table (length of each column in the staging table is 25% more data dump without errors) are different for ex: If we have the city long varchar 40 column in table staging there 25 in the base table. Once data are discharged into the intermediate table that I want to compare the actual length of the data for each column in the staging table with the database table definition (data_length for each column of all_tab_columns) and if no column is different length that I need to update the corresponding line in the intermediate table which also has an indicator called err_length.
so for that I use the cursor c1 is select length (a.id), length (b.SID) of staging_table;
c2 (name varchar2) cursor is select data_length all_tab_columns where table_name = 'BASE_TABLE' and column_name = name;
But we get atonce data in the first query while the second slider, I need to get for each column and then compare with the first?
Can someone tell me how to get the desired results?
Thank you
Manoi.Hey, Marco.
Of course, you can set src.err_length in the USING clause (where you can reference all_tab_columns) and use this value in the SET clause.
It is:MERGE INTO staging_table dst USING ( WITH got_lengths AS ( SELECT MAX (CASE WHEN column_name = 'ENAME' THEN data_length END) AS ename_len , MAX (CASE WHEN column_name = 'JOB' THEN data_length END) AS job_len FROM all_tab_columns WHERE owner = 'SCOTT' AND table_name = 'EMP' ) SELECT s.ename , s.job , CASE WHEN LENGTH (s.ename) > l.ename_len THEN 'ENAME ' END || CASE WHEN LENGTH (s.job) > l.job_len THEN 'JOB ' END AS err_length FROM staging_table s JOIN got_lengths l ON LENGTH (s.ename) > l.ename_len OR LENGTH (s.job) > l.job_len ) src ON (src.ename = dst.ename) WHEN MATCHED THEN UPDATE SET dst.err_length = src.err_length ;
As you can see, you have to hardcode the names of the columns common to several places. I swam () to simplify that, but I found an interesting (at least for me) alternative grouping function involving the STRAGG user_defined.
As you can see, only the subquery USING is changed.MERGE INTO staging_table dst USING ( SELECT s.ename , s.job , STRAGG (l.column_name) AS err_length FROM staging_table s JOIN all_tab_columns l ON l.data_length < LENGTH ( CASE l.column_name WHEN 'ENAME' THEN ename WHEN 'JOB' THEN job END ) WHERE l.owner = 'SCOTT' AND l.table_name = 'EMP' AND l.data_type = 'VARCHAR2' GROUP BY s.ename , s.job ) src ON (src.ename = dst.ename) WHEN MATCHED THEN UPDATE SET dst.err_length = src.err_length ;
Instead of the user-defined STRAGG (that you can copy from AskTom), you can also use the undocumented, or from Oracle 11.2, WM_CONCAT LISTAGG built-in function.

question: How can I open CS5.5 after the migration to the new computer laptop w / Mac OS 10.8.4? I got a dialog box indicating that I had to run Java SE runtime (or something to that effect), when I approved it, then try opening cs5.5 Indesign, the program closed unexpectedly at startup. If I uninstall program & reinstall, my documents will be free, or are they toast? Help!

How can I convert an existing table to the ITO
Hello
My Oracle version is 10.2.0.4
Here's my my test_table structure.
He has 1141580 rows.
I want to convert to table index. However, there is no secondary indexes.
How can I convert an existing table to the ITO.
CREATE TABLE test_table ( Column1 NUMBER NOT NULL, Column2 DATE NOT NULL, Column3 VARCHAR2(100) NOT NULL, Column4 VARCHAR2(8) NULL, Column5 VARCHAR2(40) NOT NULL, Column6 VARCHAR2(3) NULL, Column7 NUMBER NOT NULL, Column8 NUMBER NULL, Column9 VARCHAR2(32) NULL, ) / ALTER TABLE test_table ADD CONSTRAINT test_table_pk2 PRIMARY KEY ( Column1, Column2 ) USING INDEX STORAGE ( INITIAL 30720 K ) / ALTER TABLE test_table ADD CONSTRAINT test_table_cons1 FOREIGN KEY ( Column1 ) REFERENCES test_table2 ( Column1 ) /
Documentation Oracle say:
Redefinition of Table online allows you to change the organization from a normal table (heap-organized) to an organized in index table and vice versa.For example, you might want to try.

Hello
I found this integration for Utimaco Cryptoserver guide: http://hsm.utimaco.com/solutions/db-encryption/ and now I wonder if it is necessary to keep the original portfolio after the migration of HSM with Oracle 11.2.0.1.0. As I understand it, eventually all the necessary keys are stored in HSM. Is still used portfolio in a way or is it possible to reuse maybe after you set the METHOD to FILE sqlnet.ora?
Thank youHi flyer007,
If you used the Wallet before Oracle, then migrate the master key of TDE from there to an HSM is a renewal of key operation; the keys of the table (for the TDE column encryption), and tablespace (for TDE tablespace encryption) key is decrypted with the old key in the portfolio) and encrypted again with the new MK unified (in the HSM).
Your RMAN backup files, export files Data Pump and same 'live' in the redo logs, TEMP and UNDO tablespace can be encrypted with the old MK in the wallet, that's why we NEVER delete the portfolio.
Of course, the Oracle database automatically knows what MK he needs.
Good luck

My vSphere infrastructure 5 uses several data stores.
Two data warehouses are associated with NFS on different NAS shares.
I migrate VM to a data to another store.
The navigation data store, I see that the files are moved from the old data store to the new and that no file belonging to the migrated VM still does exist on the old data store.
If I look at the list of VMs on the old data store, I still see the old VM.
I see it in the list of the virtual machine on the new data store as well.
I checked that no .iso no pagefile is in the old data store.
How can I update the list of the virtual machine on the old data store?
Above all, how can I safely delete the old data store by ensuring that the virtual machine works very well on the new data store and I don't lose anything?
Concerning
Marius
This use of data store 'Phantom' is usually observed, if the current configuration of the virtual computer points to the 'old' data store (diskette, CD-ROM) or the virtual machine contains snapshots where - at the time where tone have been created - the VM has had these references. Once the snapshots are deleted from data store 'ghost' will go away from summary of the virtual machine.

After the migration of the catalog security issues
Hello
We installed a new environment of Sys (11.1.1.7.0) and now need to migrate the OBI of Dev (11.1.1.7.0) objects. Everything works as expected in Dev with connection and view dashboards appropriate according to the permissions of the users. Now, after the migration to Sys when we try to connect to hostname:9704 / analytic all users cannot see the table edge and catalog of objects. WebLogic even does not see everything. I can see items in catalog offline through the Manager of catalog or Windows Explorer. If I look at the catalog using the Catalog Manager my permissions do not allow me to see all items in folders. However, Dev, I am able to do. It seems that some thing is out of sync btwn the catalogue and policy store even if users have the relevant groups assigned in the weblogic LDAP. Any ideas on what might be happening or how to fix?
Migration process:
(1) store the migrated policies and identity sys Dev store. Confirmed objects have been migrated.
(2) migrated RPD and sys Dev catalog. Confirmed objects have been migrated.
(3) refreshed GUID in Sys
(4) services start successfully
Kind regards
MikeHi André.
I worked with Mike on this permissions problem and can provide feedback.
I compare the "Shared folders" privileges between the two environments, DEV (works) and TEST (does not work).
The DEV environment has:
Name - Type of permission - details-
------------------------------------------------------------------------------
-Authentication user - Application role - total control - control total
-Presentation Server Admins - role of catalog - full control - full controlThe TEST environment has:
Name - Type of permission - details-
------------------------------------------------------------------------------
-Admin BI role - Application role - full control - full control
-Role of consumer BI - custom...-read, through, etc. - the Application roleI'm changing the TEST environment to reflect our operation DEV permissions:
Name - Type of permission - details-
------------------------------------------------------------------------------
-Authentication user - Application role - total control - control total
-Presentation Server Admins - Application role - full control - full controlI am now able to log in as my administrator user and have access to the appropriate objects.
I have a few questions, I hope you can clear up however.
(1) something in our process of migration to our TEST about. must have updated the privileges of shared folders not to include roles authenticated the user & Presentation Server Admins/groups. It's weird, because we migrated all our DEV operating environment around. No indication of what we have fact/lack would be useful.
(2) authorities 'Shared Folders' REP on my DEV TEST Server vs server, the type of role is 'Catalogue', and 'Application' on the other. How we do conversion as a catalogue to an application from DEV to TEST role?
DEV:
Name - Type
------------------------------------------------------------------------------
-Presentation Server Admins - role catalogTEST:
Name - Type
------------------------------------------------------------------------------
-Presentation Server Admins - Application roleMuch obliged.
