Looking to migrate to cloud based SQL Server

Apologies, Azure newbie here.
We have a custom built ERP solution (currently installed with +50 clients).
Our architecture is based on a single database for each financial entity + a pointer database to tie them all together. Certain clients have many companies (meaning multiple databases). Financial reporting requires many cross database procedures.
All of our current clients run their own server infrastructure, but we're looking at some current opportunities where clients would like to offload this requirement to the cloud.
1. Am I correct in my understanding that Azure doesn't support any cross database joins or calls?
2. If so, can SQL server be configured so that it is exposed via an external IP address?
Many thanks :)

Hi ReflexRob,
No need to apologize - thank you for reaching out! Currently, Azure SQL Database does not offer cross database queries. However, I'd like to learn more about your scenario. Can you please email me at joseidz at microsoft.com.

Heterogeneous Migration of BW on SQL Server to BW on HANA Issue

Hi,
I am performing Heterogeneous migration of BW on SQL Server to BW on HANA according to the procedure mentioned in the SAP Documentation.
Started the migration using Software Provisioning Manager.
I have ran SMIGR_CREATE_DDL and ran export of source system and it is completed successfully.
Then I ran the Import of Target system. The import ran into issues when running the script SAPVIEW, the script resulted in failure when creating views.
(DB) ERROR: DDL statement failed
(CREATE VIEW "V_TRALAN" ( "PGMID" , "OBJECT" , "OBJ_NAME" , "AUTHOR" , "DEVCLASS" , "MASTERLANG" , "COMPONENT" , "NAMESPACE" , "TPCLASS" , "GENFLAG" , "DLVUNIT" ) AS SELECT T0001."PGMID", T0001."OBJECT", T0001."OBJ_NAME", T0001."AUTHOR", T0001."DEVCLASS", T0001."MASTERLANG", T0002."COMPONENT", T0002."NAMESPACE", T0002."TPCLASS", T0001."GENFLAG", T0002."DLVUNIT" FROM "TADIR" T0001, "TDEVC" T0002 WHERE T0002."DEVCLASS" = T0001."DEVCLASS")
DbSlExecute: rc = 103
(SQL error 259)
error message returned by DbSl:
invalid table name: Could not find table/view TDEVC in schema SAPXXX: line 1 col 386 (at pos 385)
I found that there are many tables which are missing in HANA Schema but exists in Source system database.
I checked the export scripts like *.STR and *.EXT and does not see those tables being captured.
Example table: TTREE exists in Source System database , but missing in HANA Database Schema SAPXXX.
Not sure what is the problem and how can I fix this issue. I was planning to manually move the missing tables from Source database to HANA Database schema, but that will be too much and I am not sure how many of them are missing.
Please let me know how can I fix this issue?
Thanks.

Reconfigure DPM after migrating Sharepoint to another SQL Server

How can I Reconfigure DPM after migrating Sharepoint to another SQL Server?

Hi,
I have tried this.
When I removed the SharePoint datasource from Protection group there was no option to keep or lose data.
I ran ConfigureSharePoint -EnableSharePointProtection and ConfigureSharePoint -ResolveAllSQLAliases , then refreshed view in DPM console and added SharePoint back to protection group.
The modify protection group screen showed success. looking in Monitoring, I see Consistency check failed with this error "DPM cannot continue protection for SharePoint Farm Sharepoint Farm\sqpl2008srv1\SharePoint_Config on spwfe1.internal.ermanz.govt.nz.
(ID 30184)" this followed with Recovery point failing as well and description was same error (as above).
I then removed the datasource again and created a new Protection Group and added SharePoint, but got same result. When creating the PG, it did not format space or do initial copy and CC's and RP's failed as before.
When DB's were moved to another SQL Server, SharePoint retained the same SQL name as before (uses aliases)

Related to migration of db from sql server to oracle 11 g

We're trying to migrate a Sql server managment studio database to Oracle 11g using SQL Developer 4.0. We can successfully connect to both Sql server managment studion 8.0 and Oracle 11g using the tool, as well as click through the Migration Wizard and start the migration.
This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????

Pl do not post duplicates - related to migration of db from sql server to oracle 11 g
Continue the discussion in your original thread
The error message is explicitly clear
ora :01440 : can not insert null into migrlog (id column)
Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

Migrating a table from SQL server 2005 to oracle 9i

Hi
I need to migrate a table from SQL server to oracle, both of which are on different machines, I tried using SQL server DTS export functionality selected the Oracle driver, created a DSN, but it gave error message box as shown below
Error Source: Microsoft OLE DB Provider for ODBC Drivers
"ORA 12560 :TNS protocol adapter error"
Context:Error During initialization of the provider
While i was successfully able to migrate the table from SQL SERVER to MS-ACCESS and from MS ACCESS to Oracle
thanks
abhishek

Hi
thanks warren, i just figured out that the DSN i had created while migrating data from Access to oracle was User DSN, i just created a system DSN of the similar kind and was successfully able to export the data from SQL server to oracle, the only problem being the column names in SQL server are longer than the limit of 30 characters we have in ORACLE..

Abhishek

How to Migrate Stored procedure on Sql server 2008 to Oracle Database

Guys, I need help vey badly as I am new in this field.
Problem is that, I have to migrate stored procedure on Sql server 2008 to oracle Oracle database:
Whole scenario--
1. Sql Server 2008 application on Windows server (source machine)
2. I have to migrate 70 Stored Procedure
3. To Oracle Database on Linux machine (Target machine)
Any method (no problem)
Please, help me or give me any reference as I don't know which keyword is differ in both database.
Thanks in advance

Hi,
You could the free Oracle SQL*Developer to do this.
There is information and a download link here -
Oracle SQL Developer</title><meta name="Title" content="Oracle SQL Developer"><meta n…
and information on using it for migrations here -
http://www.oracle.com/technetwork/database/migration/index-084442.html
You could use it in 2 ways -
1. Go through a migration but just pull the stored procedure code from the file created after you generate the SQL from the SQL*Server database
2. Use the scratch editor accessed from -
- Tools - Migration - Scratch Editor
and paste the SQL*Server stored procedure code into the window and it will convert it to Oracle code. The tool is very good but may have problems if you have very complicated procedures that use SQL*Server specific utilities.

Mike

Migrating 250gb from ms sql server 2000 to oracle

Hi,
i am trying to migrate data from sql server 2000 to oracle. I have tried the online method and it takes more than a day to copy one table with 250 million rows. Currently i am trying the offline method of using migration scripts with sql loader.
this also seems to be taking a very long time for the single table with 250 million rows. Is there an effective way of doing this? please help
thanks

Well, lets look at what you're doing. You're using jdbc/odbc to move 250,000,000 rows. thats like using a straw to pump gas. We recommend that any migration over 10-20 MB should be done using the offline data move.
A couple of questions
1. How fast does the bcp go? How long does it take to complete?
2. When using SQL Loader, are you loading it in raw format? Have you switched off any indexes on the table? Do you have the capability to load in parallel?
Theres a lot you can do with the SQL Loader side to make it a lot fast. You might also want to consider dropping a note on the database forum too.

Data MIgration from Oracle to SQL Server 2005

HI Gurus,
Kindly please advice me how to migrate Data from oracle to MS SQL Server or Vice Versa.
I came to know about 2 methods:
1) Using SQL Developer
2) USing ODBC.
KIndly let me know which method is better. I am in confusion about both option
Kindly advice over the same
Thanks

Usually such questions asked and answered on forums of a target system. In this case on MS SQL forums.
But I will answer.
You should create a LINKED SERVER in MS SQL that connects to Oracle.
Then issue couple of SELECT * INTO <TARGET_TABLE> FROM <ORACLE LINKED SERVER>..<SRC SCHEMA>.<SRC TABLE>.
Install Oracle Client and OLE DB driver on SQL Server machine.
Also, Oracle is case sensitive by default. MS SQL is case insensitive by default. If there are primary/unique keys that have mixed case values in Oracle, then in MS SQL you need to set case sensitive collation for them.
PS. If you need not only migrate data one time, but also to have a real time replication during an application transition period, you can take a look on heterogeneous replication solutions like Golden Gates or DataCurrents.

Migrating VB Applications on SQL Server to Oracle Forms on Oracle 10g RAC

Hello All,
I am looking at migrating a VB application built on a SQL Server database across to an Oracle Forms deployment with the data migrated to an Oracle 10g RAC database environment.
My first question is whether the SQL Developer Migration Workbench can migrate the SQL Server data to a RAC environment?
The second question is to ask whether there are any "toolkits" or tips from the community migrating VB applications to Oracle Forms.
Any advise or suggestions greatly accepted.
Kind Regards,
Gary.

SQL Developer Migration Workbench definitely can migrate SQL Server data to Oracle RAC setup.
However, I don't think VB application can be easily converted to Oracle Forms.
You can post your question in Oracle Form forum to double check.

Migrating from Oracle to SQL Server - data won't migrate but no errors

I'm attempting to migrate a database from an Oracle 11g (11.1.0.7.0 64-bit) database to a SQL Server 2008 R2 (10.50.4033.0). I'm using SSMA, and the Oracle tool was installed on the target SQL Server by the DBA. I've completed all the steps up
to and including synchronizing the database, and the empty tables all exist in SQL Server. When I run the step to migrate the data, I get:
Migrating data...
Analyzing metadata...
Preparing table POLICYS.LOGINS...
Preparing data migration package...
Starting data migration Engine
Starting data migration...
Data migration operation has finished.
   0 table(s) successfully migrated.
   0 table(s) partially migrated.
   1 table(s) failed to migrate.
Then a summary box appears, and there is a red X next to the table (I'm trying to just convert 1 small table to begin with.) What immediately appears to be wrong is that the "To" table is blank.
I've attempted this multiple times, different tables (initially tried all tables) and tried both Server Side and Client Side migrations with the same result. There are no errors or warnings on the Error List.
I've found another online post where the user had the same issue, but in that instance they fixed it by changing the case of the table name. I tried that, but it didn't help. I'm not sure what is wrong that it won't migrate any data. Any help
is appreciated. TIA

How to Migrate my database from SQL Server 2000 to Oracle

I want to transfer my database from SQL Server 2000 to Oracle, Can I do this without using Oracle Migration Workbench ??
Please help me.
Thanks in advance
Vicky... :-)

Do you have a good technical reason for not wanting to use the Migration Workbench?
Given that it's free and does a hell of a lot of the work for you, why wouldn't you use it?
Other than that, I would say you would be on your own...
cheers,

Migration of table from sql server to oracle

Hi,
I had to export few tables from SQL Server to Oracle. After the migration, I am checking to see all the tables in Oracle that have been migrated from Sql Server. I am executing select * from tab; and am seeing all the the tables (including those have been exported) from the output list of tables. However, when I am doing a select * from x; where x is one of the few tables that have been migrated, it says table or view does not exist. This is the problem with all other migrated tables. Any help is appreciated in advance. Thanks.

Try select * from "x"

Migrating from Oracle to SQL Server - SQL HINTS

We are migrating an SAP landscape from HP-UX / Oracle to Windows / SQL Server. We have numerous custom programs with OPEN SQL Hint statements of the form:
select aqmnum akunum aobjnr azztaxtype a~zzservcenter
         azzassmpriok azzaudittype a~zzdr840dt
    into corresponding fields of table lt_qmel
    from qmel as a
    inner join ihpa as b
    on aobjnr = bobjnr
    where a~qmart IN ('Z7','Z8','Z9','ZU','ZD')
    and   b~parnr = sy-uname
    *%_hints oracle*
    *'INDEX("&TABLE&" "IHPAP" "IHPAP")'.*
Question: What is the best way to make these SQL statements compatible with SQL Server?
Thanks

Hi Paul,
as hints are highly database specific it may well be that you won't need them for your new DBMS anymore.
In any case you've to review them one-by-one to check the execution plan of the queries without a hint.
A general "migration of hints" is neither possible nor sensible.
