SQL Server : When you restore a database backup to another server, you may experience a problem with orphaned users.

SYMPTOMS When you restore a database backup to another server, you may experience a problem with orphaned users. The Troubleshooting Orphaned Users' topic in SQL Server Books Online does not outline the exact steps for troubleshooting this problem.
Troubleshooting Orphaned Users When you restore a database backup to another server, you may experience a problem with orphaned users. The following scenario illustrates the problem and shows how to resolve it. A. Showing a report of the current user to login mappings
The following example produces a report of the users in the current database and their security identifiers (SIDs).
Copy
EXEC sp_change_users_login 'Report';
B. Mapping a database user to a new SQL Server login
In the following example, a database user is associated with a new SQL Server login. Database user MB-Sales, which at first is mapped to another login, is remapped
USE AdventureWorks2012;
GO
EXEC sp_change_users_login 'Update_One', 'MB-Sales', 'MaryB';
GO
Use Northwind
go
sp_change_users_login 'update_one', (restore users id)'test',(current database user id) 'test'
sp_change_users_login :
@Action
@UserNamePattern
@LoginName
@Password

Your session has expired due to inactivity. You will be redirected to the login page where you can enter your username and password" on Internet Explorer while logging into Administration Console

Cause
This issue occurs due to underscores in the hostname.
Solution
To resolve this issue, do any of the following:
•Use the physical IP address.
•Use a different browser, like Mozilla Firefox, Chrome, or Safari.
•Make DNS entry changes on the server side.

Row error occured while fetching data from database.

I am using 8.6 version and In our sql override there are couple of columns which are more than 4000 i.e string 4000 , we are taking a substruing and sending them as 1000 in sql override but still the data is getting rejected at source level. when i was going through the informatica potral i came across this infor will this help in resolving this issue... RR_4053 : Row error occurred while fetching data from database. This error occurs when no column value is greater than 4000 characters in this case. Cause This occurs when Informatica Integration Service is fetching an array.

Cause: This occurs when Informatica Integration Service is fetching an array.
Solution : Steps
1. In Administration Console , click on Integration Service
2. Expand Custom Properties
3. Add a property called OptimizeODBCRead with value No
4. Bounce Integration Service
5. With this flag the Integration Service uses the single row fetch instead of doing array fetch.

SQL Server Date Formats

SQL Server Date Formats



One of the most frequently asked questions in SQL Server forums is how to format a
datetime value or column into a specific date format. Here's a summary of
the different date formats that come standard in SQL Server as part of the CONVERT
function. Following the standard date formats are some extended date
formats that are often asked by SQL Server developers.


It is worth to note that the output of these date formats are of VARCHAR data
types already and not of DATETIME data type. With this in mind,
any date comparisons performed after the datetime value has been formatted are
using the VARCHAR value of the date and time and not its original DATETIME
value.

EBCDIC file handling

Sourcing the EBCDIC file from mainframes to Informatica can be a harder job! Verifying and managing the Packed decimals and the zoned decimals are as easy as the normal flat file handling. You should be in a position to know various flat file options to have it done!
In informatica to read an EBCDIC file VSAM source file strucure is used. Where we can prepare EBCDIC file from the flat file by the tool called 'Ultraedit'. To prepare from ASCII, first need to convert to EBCDIC format. Then to remove null spaces convert it to hex mode and serch and remove for "0D 25" with null. After that again return it to EBCDIC mode and this file with .TRX extension you can use for testing purpose.


With Regards, Sanket
Using a well known file enditor VEDIT ,the EBCDIC file can directly be edited without translating it and then can be transferred back to a mainframe computer. For transfering to a PC or a UNIX system particularly to a database such as SQL or MS Access, using VEDIT, the EBCDIC file can be translated to ASCII before transfer. The EBCDIC files that do not contain packed-decimal fields are particularly easy to translate to ASCII using the VEDIT.

Informatica Metadata Repository tables

While browsing through the Informatica rep and opb tables, we are usually stuck up as we do not understand what the widget_id and widget_types are for.
Below is the list of widget_types. This data would help us ease the handling of metadata.
Widget Ids and transformation types

97Custom Transformation

What are widget IDs and why do we require them?
Informatica maintains metedata regarding the mappings and its tranformations, sessions, workflows and their statistics. These details are maintained in a set of tables called OPB tables and REP tables.
The widget refers to the types of transformation details stored in these tables.

Port types in a transformation
As the above section details, widget is a transformation in metadata tables. To get the port type from repository table, below is the SQL snippet to use

select a.widget_id, decode(a.porttype, 1, 'INPUT',
3, 'IN-OUT',
2, 'OUT',
32, 'VARIABLE',
8, 'LOOKUP',
10, 'OUT-LOOKUP',
to_char(a.porttype)) Port_Type
from opb_widget_field a;

If you want to know the mapping name, then match the widget_id against the widget_id of opb_widget_inst and then pull the mapping_id which can be mapped against mapping_id in opb_mappings table. If you want to know the Folder name, then map the subject_id from opb_mappings to that of subj_id in OPB_SUBJECTS table to get the subject_name.

Expressions and SQL overrides in a transformation
OPB_EXPRESSION is the table that stores all the expressions in metadata.
To associate an expression to a field in a transformation, OPB_WIDG_EXPR is the table to be used.

select g.expression
from opb_widget_expr f,
opb_expression g
where f.expr_id = g.expr_id

SQL overrides can be in Source Qualifiers and Lookup transformations.

To get the SQL Override from metadata, check REP_WIDGET_ATTR.ATTR_VALUE column.

Differences between Advanced External Procedure and External Procedure Transformations

Advanced External Procedure Transformation

Advanced External Procedure transformation is an Active and Connected transformation. It operates in conjunction with procedures, which are created outside of the Designer interface to extend PowerCenter/PowerMart functionality. It is useful in creating external transformation applications, such as sorting and aggregation, which require all input rows to be processed before emitting any output rows.

External Procedure Transformation

External Procedure transformation is an Active and Connected/UnConnected transformations. Sometimes, the standard transformations such as Expression transformation may not provide the functionality that you want. In such cases External procedure is useful to develop complex functions within a dynamic link library (DLL) or UNIX shared library, instead of creating the necessary Expression transformations in a mapping.

Differences between Advanced External Procedure and External Procedure Transformations:

External Procedure returns single value,
whereas Advanced External Procedure returns multiple values.

External Procedure supports COM and Informatica procedures
whereas AEP supports only Informatica Procedures.

Difference between Connected and UnConnected Lookup Transformation

Difference between Connected and UnConnected Lookup Transformation:

Connected lookup receives input values directly from mapping pipeline
whereas UnConnected lookup receives values from: LKP expression from another transformation.

Connected lookup returns multiple columns from the same row
whereas UnConnected lookup has one return port and returns one column from each row.

Connected lookup supports user-defined default values
whereas UnConnected lookup does not support user defined values.
