Informatica PowerCenter Repository tables

I am sure every PowerCenter developer either has an intention or necessity to know about the Informatica metadata tables and where information is stored etc. For the starters, all the objects that we create in Informatica PowerCenter - let them be sources, targets, mappings, workflows, sessions, expressions, be it anything related to PowerCenter, will get stored in a set of database tables (call them as metadata tables or OPB tables or repository tables).

* I want to know all the sessions in my folder that are calling some shell script/command in the Post-Session command task.
* I want to know how many mappings have transformations that contain "STOCK_CODE" defined as a port.
* I want to know all unused ports in my repository of 100 folders.

In repositories where you have many number of sessions or workflows or mappings, it gets difficult to achieve this with the help of Informatica PowerCenter client tools. After all, whole of this data is stored in some form in the metadata tables. So if you know the data model of these repository tables, you will be in a better position to answer these questions.

Before we proceed further, let me clearly urge for something very important. Data in the repository/metadata/OPB tables is very sensitive and that the modifications like insert or updates are to be made using the PowerCenter tools ONLY. DO NOT DIRECTLY USE UPDATE OR INSERT COMMANDS AGAINST THESE TABLES.

Please also note that there is no official documentation from Informatica Corporation on how these tables act. It is purely based on my assumption, research and experience that I am providing these details. I will not be responsible to any of the damages caused if you use any statement other than the SELECT, knowing the details from this blog article. This is my disclaimer. Let us move on to the contents now.

There around a couple of hundred OPB tables in 7.x version of PowerCenter, but in 8.x, this number crosses 400. In this regard, I am going to talk about few important tables in this articles. As such, this is not a small topic to cover in one article. I shall write few more to cover other important tables like OPB_TDS, OPB_SESSLOG etc.

We shall start with OPB_SUBJECT now.

OPB_SUBJECT - PowerCenter folders table

This table stores the name of each PowerCenter repository folder.

Usage: Join any of the repository tables that have SUBJECT_ID as column with that of SUBJ_ID in this table to know the folder name.

OPB_MAPPING - Mappings table

This table stores the name and ID of each mapping and its corresponding folder.

Usage: Join any of the repository tables that have MAPPING_ID as column with that of MAPPING_ID in this table to know the mapping name.

OPB_TASK - Tasks table like sessions, workflow etc

This table stores the name and ID of each task like session, workflow and its corresponding folder.

Usage: Join any of the repository tables that have TASK_ID as column with that of TASK_ID/SESSION_ID in this table to know the task name. Observe that the session and also workflow are stored as tasks in the repository. TASK_TYPE for session is 68 and that of the workflow is 71.

OPB_SESSION - Session & Mapping linkage table

This table stores the linkage between the session and the corresponding mapping. As informed in the earlier paragraph, you can use the SESSION_ID in this table to join with TASK_ID of OPB_TASK table.

OPB_TASK_ATTR - Task attributes tables

This is the table that stores the attribute values (like Session log name etc) for tasks.

Usage: Use the ATTR_ID of this table to that of the ATTR_ID of OPB_ATTR table to find what each attribute in this table means. You can know more about OPB_ATTR table in the next paragraphs.

OPB_WIDGET - Transformations table

This table stores the names and IDs of all the transformations with their folder details.

Usage: Use WIDGET_ID from this table to that of the WIDGET_ID of any of the tables to know the transformation name and the folder details. Use this table in conjunction with OPB_WIDGET_ATTR or OPB_WIDGET_EXPR to know more about each transformation etc.

OPB_WIDGET_FIELD - Transformation ports table

This table stores the names and IDs of all the transformation fields for each of the transformations.

Usage: Take the FIELD_ID from this table and match it against the FIELD_ID of any of the tables like OPB_WIDGET_DEP and you can get the corresponding information.

OPB_WIDGET_ATTR - Transformation properties table

This table stores all the properties details about each of the transformations.

Usage: Use the ATTR_ID of this table to that of the ATTR_ID of OPB_ATTR table to find what each attribute in this transformation means.

OPB_EXPRESSION - Expressions table

This table stores the details of the expressions used anywhere in PowerCenter.

Usage: Use this table in conjunction with OPB_WIDGET/OPB_WIDGET_INST and OPB_WIDGET_EXPR to get the expressions in the Expression transformation for a particular, mapping or a set.

OPB_ATTR - Attributes

This table has a list of attributes and their default values if any. You can get the ATTR_ID from this table and look it up against any of the tables where you can get the attribute value. You should also make a note of the ATTR_TYPE, OBJECT_TYPE_ID before you pick up the ATTR_ID. You can find the same ATTR_ID in the table, but with different ATTR_TYPE or OBJECT_TYPE_ID.

OPB_COMPONENT - Session Component

This table stores the component details like Post-Session-Success-Email, commands in Post-Session/pre-Session etc.

Usage: Match the TASK_ID with that of the SESSION_ID in OPB_SESSION table to get the SESSION_NAME and to get the shell command or batch command that is there for the session, join this table with OPB_TASK_VAL_LIST table on TASK_ID.

OPB_CFG_ATTR - Session Configuration Attributes

This table stores the attribute values for Session Object configuration like "Save Session log by", Session log path etc.

Nice work Radhakrishna ..!!!

Shoaib said...

hi radhakrishna, its really cool,
can u pleaselet me know how cani pull out the details of workflow x.

i want to pull information of workflow x( its sources, its target,source read rows target read rows)

Radhakrishna Sarma said...

Hi Shoaib,
You will get all that information from OPB_SESS_LOG table.


Ravz said...

Hi Radhakrishna,
I read your blogs on informatica blog too, and found them very useful. Thanks for your sharing knowledge.
I have one query, hope you may help me out.
what will happen if the order of columns in Fixed width file or delimited file is changed?
I mean e.g. we are using a flat file in informatica with columns as A,B,C,D. What if the incoming file while running session has columns as B,A,C,D. You may assume that there will be header info in file itself?

Radhakrishna Sarma said...

Hi Ravz,

Thank you for visiting my blog, but what do you mean by what will happen? Do you mean to the source definition in PowerCenter or to the mapping etc? Or if you just change in the actual physical file and the expected behaviour of Informatica mapping built on this? Can you explain clearly what you meant?


Ravz said...

Hey thanks for quick revert.. I meant that can informatica still read the correct values from flat file. Even if order of column changes. This question was asked in one interview.

Radhakrishna Sarma said...

Hi Ravz,

Probably the order should reflect in the mapping as well? I am not sure. These are the types of questions that you will have to try and work. According to me this is not a question to be asked. This question in no way tests a person's PowerCenter capabilities.


Ravz said...
This comment has been removed by the author.
Ravz said...

Yeah I agree with you... This question will only check whether I faced such scenario or not.. anyway thanks for quick revert..

genie said...

Nice Work !

I have a question ....I want to pull source tables and the associated ports along with data type,precision and scale information......which tables can i leverage ?

Radhakrishna Sarma said...

Hi genie,

There is already, a pre-defined view that gives you all the required details.

select * from rep_all_source_flds


genie said...

yeah there is.....but if i create a new folder in informatica with new's information is not added to this view....

also....the opb_targ_fld tables has that information for targets but opb_src_fld does not.....why is it so??

Radhakrishna Sarma said...

What do you mean by information not added to the view? A view is a just a window to the underlying tables' data. So if the data is added to the tables, then it will be seen in the view. I think you need to know the distinction between a table and a view.

Anyway, for your other question, I am just assuming that Informatica treats a source as a widget and you should find all the source fields from the table OPB_WIDG_FIELD_ATTR or some table similar.


genie said...

Thanks for your quick and useful responses.... I have another one...

How can we get the field dependencies of the target ports in a mapping ??????

Radhakrishna Sarma said...

Can you elaborate on what you mean by field dependency?


genie said...

I meant that if if want to know that from where ever target port in informatica when we right click on the target port there is an option call show field dependencies !

Radhakrishna Sarma said...

Hi genie,

I don't remember exactly, but there is a table by name OPB_WIDG_FLD_ATTR or something similar whoch has each transformation and its TO_FIELD and FROM_FIELD. I think that helps to get to the bottom of that.

Having said that, I have just identified certain tables to be useful for our requirements. Its not that we can replicate each functionality the client tool provides, using our SQL join queries on the OPB tables. When we do that it is called "reinventing the wheel". I hope you understand that.

Hi Sarma,

Thanks for the information. Any idea of what is the full name of OPB?

prasuna said...

Hi Radha Krishna,

In one interview ..they asked me..the metadata will be stored in which format???can i know thw answer please??

Radhakrishna Sarma said...

Hi Prasuna,

As my article above says, it is stored in database tables.


Anonymous said...

very informative.. thanks for sharing your knowledge.. I have one question in my repostitory DB I have a lot of duplicate tables like for mapping I have "OPB_MAPPING" and "OPB_MAPPING_" is it something generic or may be it is created by someone from our DBA team.

Radhakrishna Sarma said...

It's just your instance that has the duplicate tables.

Seetha said...

Hi Radha,

All your posts are very informative..thanks for sharing your learnings..
I have a doubt. I need to pull only the source columns which are connected to a Port. Can I make use of REP_ALL_SOURCE_FLDS view? I couldnt find any column storing the port info in this..


Radhakrishna Sarma said...

Hi Seetha Laksmi,

There are 3-4 tables to be jopined before you can get the information relating to your query.

opb_widget_field - Field name, Field ID (port), Widget ID etc.

OPB_WIDGET_INST - Widget ID, Instance ID, mapping id etc.

OPB_WIDGET_DEP - Mapping ID, From Instance ID, To Instance ID, From Field ID, To Field ID.

But this is a source definition and you wouldn't find the WIDGET_ID in OPB_WIDGET and so you should check it against the SRC_ID in OPB_SRC table.

I hope this helps.

Can you please let me know how to capture the sequence of workflow tasks that are executed using these repository tables?
The Informatica Workflows in the current system are several level deep (involving several layers of Worklets). We are looking for a way to get a list of the operations performed in each of the workflow in the sequential order. This will enable us to design the new orchestration process.

Kavitha said...

Hi Radhakrishna,

Thanks for providing the details of Informatica Powercenter repository

Metadata details. Will it be possible to get the dates for each action

taken place while chaning the mapping,session,etc., logics/conditions

for audit trail.


abdulmalik said...

Thanks a lot RadhaKrishna for sharing this knowledge.

I've looked into many table and it's attributes, however unable to find the bulk load option column, it's value and table in which it could be present. Could you please help us in this.

Thanks & Regards.
Malik Ahmer.

Radhakrishna Sarma said...

Hi Malik Ahmer,

The Bulk/Normal option is an external attribute. So you will find it in opb_extn_attr table where attr_id = 3 for a given sess_widg_inst_id, which can be derived from

select sess_widg_inst_id from opb_swidget_inst
where widget_id =
and instance_name =
and session_id = ;

Take this and get the attr_value. If the attr_value = 1, then it is Bulk and if it is 0, it is Normal.

select attr_value
from opb_extn_attr
where attr_id = 3
and session_id =
and sess_widg_inst_id = ;


Abeesh said...

Hi Radhakrishna,
I need to get the throughput(bytes/sec) of session. Can u tell me which OPB tables stores this info. I can get the throughput(rows/sec) from rep_sess_tbl_log but bytes/sec is not available. Please help

How to find out all the connection names,connection server,folder name, worklow name, mapping name,target and source details for a particular connection server ?
Can you please provide the query for the same

Pradeep Kothakota said...

Hi Radhakrishna,
Nice Work.
I have set of workflows.I want to check whether "Fail Parent If this task fails" is checked in all sessions or not. How can i check this using Repository tables?

Pradeep Kothakota said...

Hi Radha,

This is Pradeep working in HP,Bangalore.

I have a doubt. I need to know workflow names, session names , source names and target names in a folder . How do I get it by querying on repository tables.

This is My query to get wf name, session names in a folder:

select f.SUBJ_NAME AS FOLDER_NAME,wf.TASK_NAME as WORKFLOW_NAME, sess.INSTANCE_NAME AS SESSION_NAME from opb_subject f,opb_task wf,opb_task_inst sess,opb_task_inst wf_inst
where wf.subject_id = f.subj_id
AND wf_inst.task_id = sess.task_id AND wf_inst.workflow_id = wf.task_id AND f.subj_name = 'usr_mohantde' AND
wf.task_type = 71 AND sess.task_type = 68

Radhakrishna Sarma said...

Hi Pradeep,

I can't give you a complete query now, but it is worth checking OPB_TDS, OPB_SRC and then match the widget_id against the opb_widget_dep or something like that.

Pradeep Kothakota said...

Thanks Radha

Pradeep Kothakota said...

Hi Radha,

Following query is giving me WF, session, mapping, src instance and target instance names. I want to get the original source and target names. How do I get it..? Which table gives me the original table names..?

opb_mapping m,
where WF.IS_VISIBLE = 1
AND se.task_id = s.session_id
AND s.mapping_id = m.mapping_id
AND SRC.MAPPING_ID=m.mapping_id
AND TGT.MAPPING_ID=m.mapping_id
AND F.SUBJ_NAME = 'usr_kothakop'

Bijjala said...

Hi Radhakrishna
can you please let me know in which OPB or REP table we will find "suspend on error" details, as we need to know which all workflow dont have this enabled. thanks in advance

Radhakrishna Sarma said...

Kumar - There is a table called opb_swidginst_log which has THRUPUT for through put. You just have to match the task id for session, its target & sources with the swidget_inst_id & you can map the target id or source id with the widget_id in opb_swidget_inst. I hope you can write the query with this information.

Can you please let me know which opb or rep table have the source qualifier sql query information.


Radhakrishna Sarma said...

Frank - The table is OPB_WIDGET_ATTR and the query is going to be in attr_value column where attr_id = 1. Widget_type you can check against the OPB_OBJECT and take the object_type_id from there.


Anonymous said...

Hi Radha,

I hope you can advise me...

I am trying to get a list of all the mappings that use a particular Target table. I have written the following query:


This seems to work well, except there is a mapping missing from the listing which I know for sure has this target table.

Have I joined the right tables/columns? Am I missing something out? Could it be a problem because the Target table is a global object in another folder and is used as a shortcut in the mapping in question?

Thanks in advance for your help
(we are using Informatica 8.5.1)


Radhakrishna Sarma said...


select distinct m.mapping_name

Rupert Holden said...

Hi there - just found your blog and really impressed.
I have a query that I am trying to work out and do not think you have already covered elsewhere....
I am trying to write some sql to emulate some of the information shown in the spreadsheet when you select "Export Metadata" for a mapping from within the Repository manager.
This "Informatica" spreadsheet includes a tab called "Target" and I am trying to write the code to get the physical names of the table and field of the targets along with the formula/expression and type shown in the "Transformations" section of this tab.
I am thinking that this uses the "OPB_WIDEGET_xxx" tables and "OPB_MAPPING" tables but am struggling to reproduce the information as shown in the spreadsheet.
Any guidance greatly appreciated, many thanks, Rupert

Jeevan said...

Hi Radhakrishna, seems like your blog has become a stop for all repository db queries! very helpful information.

I have hundreds of mappings with mapping level source qualifier override in almost each and every mapping. I want to list the origination point of all target table fields. I am able to get the sql override, source and target columns. But, is there a way to link the target field to specific field mentioned in the sql override?

Example - [Target] FieldX might appear to have been connected to [Source] Field1 but, the sql qry overrides this to have been sourced from FieldP. In the list I am trying to create, I want to have FieldP (not Field1) opposite to FieldX

Looking for your response.

Hi Radha,

I am using PowerCenter 9.1.0.
This is related to calculating memory configuration.

Is there any table or query that would help me to calculate the memory configuration, whether is it set correct or not?

I saw somewhere an online doc, where it says, we can calculate, if we get the below details for a particular session :
1. lookup - no of unique rows
2. aggregator - no of groups
3. sorter - no of rows to be sorted
4. rank - no of ranks specified inside mapping
5. maximum memory allocated for auto memory attributes
6. maximum percentage of total memory allowed for auto memory attributes

Let me know your comments/suggestions on this.

Thanks in Advance.

Hi Radha,

Does any metadata tables get updated when a object say workflow in copied from one repo to another.

We need to check logs when a object is copied, Any idea how this can be accomplished without Deployment group.


Vipin Chaudhary said...

I have workflow which is running in 10 instance. Each instance will run for 20 mins and thus it is running 24*7.

This workflow has 3 session. I want to know the whether 2nd session is running or not if not than need to check the status of 1st session if it is running than will check source rows and if source rows are 0 then will abort the workflow.

Please suggest unix script for the same.

Thanks in Advance.
