OWB 10gR2: Commit everything or nothing

Hello.
We have a mapping which must run in row-based mode because it deletes records. There is one source and multiple targets. One flow directs into a logtable (LOG_LT). The other flow directs into 4 targets (MOD_LT for all targets) depending on the mode given in the recors (Update/Insert/Merge/Delete). The Logtable gets a part of the primary keys of the incoming rows wich are used for a replication application.
It is important that there is nothing in the 4 targets which is not stored (part of pk as described) in the logtable. Otherwise information will be lost for the replication.Therfore we set target to order to use the LOG_LT first.
a) We started with a high commit high freqency larger than the number of rows in source and autocommit. If the data flow had a error (pk e.g.) only this and not the log-flow was rollbacked. (Table based rollback)
b) We used autocommit correlated. The logflow and the dataflow are ok, but the mapping was commiting to early (not the value in commit freqency).
Why?
c) The next idea was to set the mapping to manual commit and commit in a postmapping procedure if everything was ok. The mapping can be deployed but when we start the mapping we get the warning:
RTC-5380: Manual commit control configured on maping xy is ignored.
Why?
Has anybody a good practice for a row-based-mapping (with multiple targets and one source) to commit everything or nothing?
Thanks for your help
Stephan

Hello Stephan,
In row based mappings, and one having single source and multiple targets then the following are the different ways of loading the targets.
1. Correlated Commit = true and Row Based - Suppose there are 50 rows in the source and there are 4 target tables. When the mapping is run in this mode ansd suppose the mapping encounters error while loading row 10 in target table say TGT_3 then this row will be rolled back from all the four targets and the processing will continue, thus finally loading 49 records in all the 4 tables.
When you run in row based mode, then please check the bulk processing mode. If it is set to true then the bulk size overrides the commit frequency set by you. It is thus advisable to make th bulk size and the commit frequency equal or set the bulk porcessing mode to false and then set the commit frequency.

Storing degenerate dimension info in an OWB 10gR2 cube

Hi,
I'm looking to store "degenerate dimension" information in an OWB 10gR2 cube. Typically in a DW, I'd just add a column to the fact table to hold the information. However, in OWB 10gR2, I don't see any way to add a column to a "cube" object - everything appears to either have to be a dimension surrogate key, or a measure.
Not sure the best way to proceed. We've coded all our ETL using the standard cube objects and letting OWB do all the surrogate key lookup, etc. automagically for us, so I'd hate to be forced to go back to manually loading the fact tables. Is there an easier way?
Thanks,
Scott

Hi Scott,
The problems I've run into with dimensions and cubes are:
Dimensions abort if there are many roles - about 4 is the limit. This is very bad for the time dimension which should have 100s of aliases. Unfortunately I can't use the Time dimension wizard because we require ISO-Weeks. My workaround is to create several Time dimensions manually and assign 4 roles to each.
Naming - when I create several time dimensions with 4 roles each (see above), in the BI layer, the foreign keys in cubes are always named something like time_dim, time_dim_1, etc rather than named for role names. I have to manually rename them in tables and then when I deploy BI objects, manually rename them again in Discoverer Administrator.
Redeploying just about anything is broken. Table upgrade plans are invalid (even after running the grant scripts that support recommended), Redeploying BI objects runs successfully but if you read the job output, it does nothing since the objects already exist - again, the upgrade option does nothing.
Column ordering is random when deploying objects so I've taken to sorting alphabetically for our BI objects. Not ideal by any means.
As for the time savings with lookups, I don't save nearly that much. Due to many composite keys in our source systems, I assign surrogate keys in our staging area. These become the "business keys" in our DW layer and consequently I end up doing lookups against the staging MAP tables - really no more or less difficult than looking up dimension keys. That is more a design choice than anything and may just be my "Kimball" habits dying hard.
I'm encouraged to hear that you are having success. I chose to utilize the Dimensions and Cubes and so far am sticking with it. I'm hoping that there will be patches and/or point releases to OWB soon!

OWB 10gR2 - some enhancement requests

Hi, I've been working with OWB 10gR2 for approximately a week now, and I've come across a few (minor) bugs, as well as a list of enhancements that I think would make the tool better. I'd like to surface these in this forum so they can be either disagreed with or have workarounds suggested, as well as getting this list in front of Oracle. Also I'm new to the tool, so maybe there are ways to accomplish what I want.
p.s. as a side note - please don't take these as criticisms of the tool. I'm actually very impressed with OWB 10gR2, but just want to surface some ideas that I think would make the tool better.
Thanks,
Scott
---Bugs:
1.     If I enter a quote character in one of the business description fields (i.e. for a cube or dimension), it causes the DDL scripts to blow up. It probably mentions the list of valid characters in the users guide somewhere - but if a character isn't legal, it should be flagged when I try to enter it originally not when deploying
2.     I can enter illegal strings in an expression operator that fail validation there, but the whole map still passes validation. For instance, I put in an expression (for a varchar2 field) using a single quote at the start, but mistakenly with a double quote at the end. I didnt bother to validate this within the expression. The whole map validated fine, but (of course) blew up with the illegal syntax when generating the code.
3.     I get the following error when trying to browse a cube (ROLAP, not MOLAP) through OWB, but I'm able to pull the cube up fine using either the excel add-in or biBeans: CubeDV_OLAPSchemaConnectionException_ENT_06952???
---Enhancement Requests:
1.     Add a deploy button in control center next to the to default actions and reset actions buttons
2.     Allow an option to have dimensions and cube defaults set to either deploy all, deploy data only, deploy catalog only, deploy aggregations (for cubes). Also, why is the default set to deploy data only? Does deploying the CMW2 metadata involve huge performance impacts or something? It seems like the CMW2 is almost free so it should be turned on by default. Its a pain to use the dimension wizard, but then have to go in to each dimension afterwards to set this option.
3.     When using configure on dims and cubes in control center, the first time the configuration properties dialog pops up, everything is fine. However, when you try to configure the 2nd object, the background focus switches from control center back to design center. This makes navigation very slow if you have lots of items to change. I've noticed this behavior in a few other places as well.
4.     Some dialogs do not have maximize buttons (i.e. dimension wizard dialogs), and default to a very small size. It is possible to have size of dialogs dynamically scaled to screen resolutions, and attempt to size columns so they fit properly. Or better yet, have each dialog remember how large it was last time, and automatically open up to that size?
5.     When generating the autobind relational table while creating a dimension, it seems to be randomizing the order of the attributes within a level (although it does sort the top level attributes first, followed by lower level attributes), at least when using the dimension wizard. It would be nice if the attributes in the relational table came out sorted in the same order as they are specified in the attributes tab.
6.     When using a unmapped display set there doesnt seem to be a way to refresh the set (i.e. remove the items that have since been mapped) unless you select all and then unmapped again. Would be nice if you could simply choose unmapped again and have it refresh the object
7.     While doing a mapping, right click on canvas allows option to generate. Would be nice to also add the validate option to this menu
8.     Validating mappings takes a decent amount of time would be nice if a busy icon was displayed to let user know that OWB hasnt locked up.
9.     default size of job details dialog is too small, and even if I maximize I still have to go through and manually adjust the size of each pane. Similar to enhancement #4
10.     Horizontal size of operators in mapping seems to be determined by the length of the operator name, instead of tying directly to the icon. Looks strange. Very minor
11.     When displaying dimension objects in a mapping:
a.     For the surrogate key columns add an icon to indicate this attribute is a surrogate key. Likewise, since its not legal to map anything to this column, remove the little arrow next to it (the one that turns gray when something is mapped to a column), or perhaps don't even show this column at all.
b.     For the business key columns add some type of icon to show which attributes represent the business natural key (or make color different, etc.)
12.     Similar to #11, for the cube operator in a mapping:
a.     For the surrogate key columns if they cant be mapped to, then dont show them
b.     For the business key columns add some type of icon to show which attributes represent the business natural key
c.     Separate the measure columns from the dimension columns
13.     For the Aggregation operator can you move the <None> default operator to the top of the list. At the bottom, it means you always have to scroll to use the most common operations (which are at the top of the list), i.e. sum and avg, etc.
14.     In the log on prompt, if I choose SQL*Net connection, every time I start it up it defaults to the details being shown (even when I chose no detail last time), with cursor in the host box. I should be able to have the details hidden, and this dialog should ALWAYS default to having the active cursor in the password box on startup
15.     When printing in a mapping, the page setup print dialog is very slow. Also, the print setup dialog shows margins, but you cant adjust them. It would be nice if this could be changed here
16.     Add a print preview icon to all of the toolbars. Printer icon is there, print preview should also be.
17.     In the dimension attributes, we need a way to tag an attribute as being the insert record date or the update record date. The corresponding MERGE SQL should be updated to use these attributes.
18.     It would be nice if the mapping canvas defaulted to an unlimited sizei.e. when I want to add new operators and the screen is already full, I either need to shrink the zoom factor down to the point where I cant read the icons anymore, or I have to pick up the new operator and drag at the bottom / right side until it scrolls enough to drop it where I want. If the canvas had an unlimited size, I could simple use the scroll bars to scroll to where I want.
19.     Scroll wheel functionality to zoom in / out (and have it zoom in around the currently selected object)
20.     Option to have operations automatically resize when longer attribute names are added to them (can workaround by mimimizing and then maximizing, but would be better to have the operators automatically adjust size to fit)
21.     Ability to sort output attributes in an operator (just like table column sort functionality). If I create a new operator, it would be nice to group it with related operators instead of always having it at bottom.
22.     re: column sort functionality drag and drop instead of up/down arrows would be nice
23.     It would be nice if, when adding output attributes to (for example) the expression operator, it would choose the default data type the same way the dimension attribute wizard works (i.e. if it sees ind in name, automatically choose char(1)
24.     Change the zoom in button so that it zooms in on the currently selected operator i.e. if I click on a particular table and then hit the zoom in button, it should keep the table I selected centered
25.     When in a mapping, clicking on a line should highlight the attributes on both the source and target operators (to allow easier visual ID of where data is coming from / going to)
26.     AWM has a feature where table attributes can be sorted so that mappings between them don't have "crossed" lines. Similar functionality in OWB would be very appreciated. It may be harder to automate this, but even manual drag and drop of attributes within an operator would be nice.

if you could copy/paste this whole thing into the submission form (see feedback option under the numbers menu). The more people that request these features, the more likely we are to see them in an update or the next version.

OWB 10gR2 License

Hi All,
We have installed the Oracle 10g2 enterprise database which has core ETL features for OWB 10gR2. We have not purchased the ETL option for OWB. Can we use Dimesions and Cubes as target table ?? Are Cubes and Dimensions only available with ETL option purchase ??
Thanks,
Sam.

What are you doing with a dimension when you can only specify SCD1. nothing
To me it's a joke that Oracle says that it's possible to use dimensions when you need the ETL option to be able to use SCD2. Most dimension's I have seen the last years have been defined as SCD2 and not SCD1. So what does it help to define a dimension if you can't use it afterwards in the mappings.

OWB 10gR2 "Experts" - does documentation exist?

Do any sources of information on OWB 10gR2 experts exist anywhere? The users guide has almost nothing about them, and the API / scripting reference doesn't mention them. I'm specifically looking on how to write experts to streamline tasks such as copying expression operators from one map to another.
There seems to be a huge amount of power in these, but without docs we really won't be able to harnass it.
Any help is appreciated!!!
Thx,
Scott

Hi Scott.
Hummm.... I've tried google (owb+experts), found some info in:

My ipod doesnt have headphones in but it says it is and i cant hear anything ive tried everything but nothing works help!!

My ipod says theres headphones in but there isnt ive tried everything but nothing works help!!!

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.

On the oracle blogs it was suggested that this can be achived by using XML function in the expression operator.
But while using them,OWB is not recongnising these XML function.

OWB 10gR2 : How to configure ctl and log locations for Sql*Loader mappings?

Hi all,
I'm using OWB 10gR2 to load data in tables with Sql*Loader mappings.
In my project I have a datafile module and an Oracle module.
When creating an sql*loader mapping in the oracle module, there is two properties for this mappings that I want to modify. The first is Control File Location and the second is Log File Location. Values for those properties are equal to the data file module location. When trying to change those values I can only chose "Use module configuration location".
Somebody knows how to configure those properties with different locations as the one of the flat file module?
What I want to do is to store the data file in one directory, and control file and log file in other directories.
Thank you for your help.
Bernard

Hi,
You're right, my problem is that the dropdown only show the location associated with the flat file location even if I have other file locations created in the design repository.
The good news is that I have found the solution to solve the problem :
1) Edit the file module and in tab "Data locations", add the locations you want to use for control file and log file.
2) Open configuration window of the mapping and then the dropdown for properties Control File Location and Log File Location show new locations
I have tested my mapping after changing those properties and it's working.

OWB 10gR2 on DB 11g and Workflow installation

Hi all,
my customer has a data warehouse running on Oracle DB 10gR2 - 2 nodes RAC - on Linux 32 bit (Red Hat enterprise 5);
ETL is developed with OWB 10gR2 and exploits Oracle Workflow (2.6.4).
They are going to upgrade the database to 11.1 (still 2 nodes RAC) on Linux 64 bit (Red Hat enterprise 5),
and they would prefer to avoid OWB upgrade.
On Oracle Support, it seems that OWB 10gR2 is certified on DB 11.1,
so our idea is to install a OWB 10gR2 repository on DB 11.1 and then export/import MDL
from current repository (OWB 10gR2 on DB 10gR2) to the new repository (OWB 10gR2 on DB 11.1).
My first question is related to Workflow:
is it correct to install Workflow on the new DB 11.1 using the software available in the home of OWB 11g software ?
is it guaranteed thet OWB 10gR2 installed on DB 11.1 will have no problems in using such installation of OWF ?
or should we install OWF 2.6.4 on DB 11.1 using the same software that was installed on db 10gR2 ?
My second question is related to *32 bit vs 64 bit platform*;
intuitively, we should install the 64 bit version of OWB 10gR2 (and OWF) on the new plaftorm hosting DB 11g:
is ita potential issue for the OWB repository migration ?
on our pc of course we will go on using OWB Client 32 bit: are there compatibility problems?
Thanks
Silvio

Hi Silvio,
is it correct to install Workflow on the new DB 11.1 using the software available in the home of OWB 11g software ?It is better to use Oracle Workflow from DB 11g.
is it guaranteed thet OWB 10gR2 installed on DB 11.1 will have no problems in using such installation of OWF ?As I know DB 11gR1 contains also 2.6.4 Workflow release, so you won't have any problem
My second question is related to 32 bit vs 64 bit platform;
intuitively, we should install the 64 bit version of OWB 10gR2 (and OWF) on the new plaftorm hosting DB 11g:
is ita potential issue for the OWB repository migration ?IMHO it is not problem
on our pc of course we will go on using OWB Client 32 bit: are there compatibility problems?There are no any problem with 32bit OWB client and OWB repository on 64bit platform

OWB 10gR2 - Implementation Strategy

I am trying to find what is the best strategy to install and configure a OWB environment for the following scenario on one linux server machine:
There are three Oracle databases on this machine:
database 1 = OWB repository owned by a owb_owner schema. The repository will contain all of design metadata (Source Oracle module with source tables, Target "Oracle module A" with tables, sequences, mappings and Target "Oracle module B" with tables, sequences, mappings). The ETL process is setup to transform data in two stages: 1> Source to target A 2> Target A to target B
database 2 = It will have target schema Target_A. The contents of "Oracle Module A" from the OWB repository in database 1 needs to be deployed to this "target_A" schema
database 3 = It will have target schema Target_B. The contents of "Oracle Module B" from the OWB repository in database 1 needs to be deployed to this "target_B" schema
Do I need to have OWB repository installed in database 2 and database 3 and have control center service running in each of them to facilitate execution of ETL process?
Deployment of the objects will be launched from a windows workstation via client design center / control center manager. Do I need to have control service running from client machine to facilitate deployment ? If so, would it facilitate deployment of the objects to the above two targe schemas ?
The intent is to have a process flow in OWB metadata repository of database 1 streamline the complete ETL process tied to a location owned by OWF_MGR schema in database1.
Please advice what implementation strategy will work best for the scenario. I read strategy presented in http://download.oracle.com/docs/cd/B31080_01/doc/install.102/b28224.pdf .. BUT I need more clarity on the available options.

Hi.
you will need a unified repository in each database. The unified repository in OWB 10GR2 contains both the objects for the design repository (your mappings, tables etc.) and the control center repository (runtime and deployment information such as execution times of mappings etc.). In previous versions of OWB they were separate.
Database 1: Install the unified repository and just use it as your design repository. You will use this when you log in via Designer.
Database 2: Install unified repository together with Control Center Service and use as control center repository.
Database 3: Install unified repository together with Control Center Service and use as control center repository.
While it is possible to have the Control Center Service just run on a client machine , I ran into all sorts of problems in the past with this configuration, e.g. when you log off your client machine it shuts down the Control Center Service. From my experience this setup is not very stable.
In OWB Designer you can then set up locations and configurations to deploy your mappings to database 2 or database 3.
You will need owf_mgr on both database 2 and database 3 and you need to deploy your process flows to both databases. What you can't do is to run a process flow say from database 1 or database 2 across databases 2 and 3.
Can you explain in some more detail why you have a requirement to transform data across two target servers?
Regards
Uli

OWB 10gR2 Architechture

The documentation says about 2 architechtures. One with Both Metadata repository and Runtime repository in the same schema and other with seperate schema's like in 9.2.
But when I tried to install from the downloaded OWB 10gR2 software from OTN. There is no option where in I can select 2 schemas seperately for Metadata and Runtime.
Please some one let me know how do I install with Metadata and Runtime in seperate schemas.
Regards
Kishore

Any repository includes both the design (metadata) and runtime components - there's no way to install it with only one or the other. Having said that, it's completely possible to just not use a repository for one function or another.
Hope this helps,
Scott

OWB 10GR2 - Information

Hello,
I just want to know if the software OWB 10gR2 is still maintained by oracle (evolutionary maintenance) or in order to fix some bugs we have to upgrade to 11g ?

I guess it depends on the nature of the bug in order for you to successfully upgrade to 11g.
