ACS 5.4 database view reinitialization question

Hello all;
Yesterday, we had a potential issue with the database view. When I tried to look into the dashboard, it kept giving me an error and said that the database view was unavailable. I pinged every device, and was able to remote into the logging device. I have notes from the previous TACACS admin, who advised that it is sometimes required to reinitialize the database view.
So, after running the patch to get into the Linux kernel on the 3415 logging server, I was preparing to launch the commands. But in his notes, he put " Soapbox" and made some side notes about doing this. He indicated that he would take the logger out of the environment, and put it as it's own primary instance first. Then, once it was working stablely, he would then re-initialize the database. Once done, he would re-add the device to the distributed environment. So:
I dont know if the screen shot uploaded. However, let me describe. When you go into System Admin>Operations>Distributed System Management, it shows you the primary instance, and the list of secondary instances below. I'm thinking that you put a check mark next to the device you want to remove, and click on the button "deregister". That "should" take it out of the distributed system. I'm guessing then that you can promote it to be it's own primary device. Then, log into it via CLI and re-initialize the database.
The main question I have is this: if I deregister it, does it fall off the list? Or does it get grayed out, so it can be put back into the distributed environment? I'd just had to deregister it and it fall off, and I dont have any of the settings or anything saved to put it back in.
Help appreciated :)

Unfortunately, database replication (trigger update) cannot be performed as it requires both the ACS boxes to run same code.
If you meant migration then yes that can be done.

second question can I use my secondary ACS for the DataBase repository?

Hi,
You should use an nfs server, sftp or ftp repository for backups only, something that is dedicated for storage. I would not recommending using anything that is used for production which needs internal storage to take on the task of managing another applications data.
As far as the the first question, i am not talking about the purging, i am talking about the scheduled application backups:

Snowflake dimension: named query vs. database view

A test question features a Product table with a Product Size code; Product Size description is taken from ProductSize table. As far as I can tell, the question asks me to choose between (a) setting up a database view joining Product and ProductSize, and
(b) doing the join in a data-source-view named query. I don't see a clear winner. (My thinking is as follows. Yes, he view would speed up the processing, even if not materialized. On the other hand, with a small dataset, the performance gain would be
minor in absolute terms. Do I want to have an extra database object in the picture?) Yet the question's author does. Can anyone advise please?

Hi Demyan,
According to your description, you want to know which is better, using named query in datasource view or using database view, right?
Based on my research, there is no performance differences between using named query in datasource view and using database view because they both result in SQL query being sent to the source system. Here is a blog which discuss this issue.
Consistency: If you already have logic in database views, I would continue to use them. As long as you know that you go to one spot to view/change the logic. Putting the logic in 2 different spots could lead to confusion.
Security Permissions: often you may not have permission to alter the source databases, in this case you have no choice but to setup named queries in the dsv.

Bad performance when using complex database view with Toplink

Hi
Problem description
1. I have a complex query that collects the data from many DB tables. For this reason I create a database view based on this select. Using EJB 3.0 with Toplink I
mapped this view to a java object the same way I map database tables. The method I use to get the results is:
snippet code...
public List<VwKartela> VwKartela(Integer pperid) {
List<VwKartela> results = null;
Session session = getSessionFactory().acquireSession();
ExpressionBuilder bankfile = new ExpressionBuilder();
Expression exp1 = bankfile.get("perid").equal(pperid);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(VwKartela.class);
query.setSelectionCriteria(exp1);
results =(List<VwKartela>)session.executeQuery(query);
When running the select on the view prom SQL Plus I haven’t any performance problem.
2.Question: How can I improve the performance? I referenced to Toplink docs but I didn't improve the it.
Have anyone any experience is such cases?
Thank you
Thanos

Hi
After my last tests I conclude at the followings:
The query returns 1-30 records
Test 1: Using Form Builder
- Execution time 7-8 seconds
Test 2: Using Jdeveloper/Toplink/EJB 3.0/ADF and Oracle AS 10.1.3.0
- Execution time 25-27 seconds
Test 3: Using JDBC/ADF and Oracle AS 10.1.3.0
- Execution time 17-18 seconds
When I use:
session.setLogLevel(SessionLog.FINE) and
session.setProfiler(new PerformanceProfiler())
I don’t see any improvement in the execution time of the query.
Thank you
Thanos

Problem creating Database view

Hi ABAP experts,
I have created an ABAP database view with tables /SAPAPO/MATLOC, /SAPAPO/MATKEY and /SAPAPO/LOC.
I am taking snp planner (PLANNER_SNP) and ppds planner (PLANNER_PPS) from table /SAPAPO/MATLOC. I want their descriptions also in the same view which is there in an another database table /SAPAPO/PLANNER. but when i use this table in the join number of entries in the view appears to be zero. I dont know why..
Can anybody suggest me how can I put descriptions of SNP planner and PPDS planner also in the same view.
Also view is getting created with all the fields as key fields by default but I want only three feilds to be the key feilds.
Can anybody help in this matter.
Thanks a lot
Best Regards,
Chandan Dubey

I can't see the structure of these tables but apparently your join condition is not well done. Ensure foreing keys for /SAPAPO/MATLOC exist in /SAPAPO/PLANNER (or vice versa dependig on which table has primary key) . Try doing a view first only with these two tables, then if this works expand it to the two other tables. This will give you an overview were is the logic (relationship) problem.
As for your second question system will suggest key relationship, of which you can delete some relations. In this case you don't need to use all of them but only part of the key fields to be compared. Just select relationship you don't want and delete it. when using this view only these fields will be used to formluate join condition.
I hope this helps you

'GROUP BY' clause in Database views

Hi,
I use SE11 to create database view from a table. I wonder if it is possible to specify a 'GROUP BY' clause? Basically I need a database view that looks like this:-
SELECT FISCAL_PERIOD, SUM(QUANTITY)
FROM TABLE A
GROUP BY FISCAL_PERIOD
Please help!
Thanks,
CH

Yes. I want to create a view that has values that are already aggregated by a field.
Example view that i created directly in SQL database:
CREATE VIEW ABC (F1, SUM_QTY)
AS SELECT F1, SUM(QTY)
FROM TABLE1
GROUP BY F1
My question is how to achieve the same result using Database view in SAP through transaction SE11 or any others?
Thanks,
CH

Using Database Views in ADF

Hi,
There are Two Views in My Database and I need to join these Views as one new VO in my ADF app. (and then I need to join this VO with another entity in my app)
I tried to make Entity object of those Views but it seems that you can not make an Entity out of a Database View (and it reasonable !)
but how can I accomplish such scenarios ?
JDeveloper : 11.1.1.6
Thank you
Shahab

this is to poster.
am not hijacking this thread., i had a question with frank.
However, for CRUD operations this could soon become hairy.
go by creating two entities. Dependent on what needs to be updated in the database, you then override the doDML method of the EntityImpl classes with calls to >e.g. stored proceduresthis is to frank.
i need a confirmation for above statement.
if a dbview involves more than 1 dbtable means say as example: 3 table means
if i take a dbview as a single entity object means, how could i perform CRUD operation?it's not possible.. am right?.
so only you are saying take 2 eo make it a view (access through eo object),do crud operation seperate beyind business need.
so only you are saying become hairy

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.

Is the best practice to use database views or view objects?

Hi everyone,
If the option is available, is it preferable consolidate as much data as possible into a database view instead of doing this through view view objects? It seems the answer would be yes, but I would like to hear the pros and cons related to performance, etc.
While I do not mind a detailed discussion, practical "rule-of-thumb" advice is what I am after; I am a newbie that needs general guidelines - not theories.
James

Performance is the main driver behind the question because I am wondering if it is faster to send a single large record set across a network or several small ones and "assemble" them at the client level.
Probably is better to send one large record, but you will need to take in account time required to create this one large record in db(maybe oracle object types, or arrays of oracle object types).
Check this for some VO performance advices: Advanced View Object Techniques (especially property: "In Batches Of" which defines number of roundtrips between app server and db)
As far as creating an updatable database view, I know there are minor tricks that are required to make that happen from a strictly SQL standpoint. But, I am curious the best way to go in JDeveloper.

Determine if database view column is foreign key in underlying table

Hi,
I have posted this same question to the General Database Discussions and JDBC forums.
I am using Oracle database 10g (10.1.0.4.0 - 64 bit production) standard edition on Red Hat Enterprise Linux AS release 3, JDK 1.4.2 and the latest Oracle JDBC (thin) driver.
We have a java GUI application that is a front-end for our database. Some of the data entry screens display data from database views. If a column in the view is a foreign key in the underlying table, we want to display a combo-box with the valid values so that the user can choose a correct value.
Is there some way to know whether a column in a view is a foreign key in the view's underlying table?
Thanks,
Avi.

I take that back.. I did figure something out for ya.. After reading some elses post I wrote this code... but its time to go home... I believe this will show you all the constraints and constraint types for the underlying tables of all the views for a user. You can mess with it and get it to return only FK (constraint_type = 'R') and only for a single view if ya like... The all_dependencies data dictionary view is the key to this whole operation...
select con.table_name, ucc.column_name, con.constraint_name, con.constraint_type
from all_constraints con, all_cons_columns ucc
where con.owner = user and
con.owner = ucc.owner and
con.table_name = ucc.table_name and
con.table_name in
(SELECT referenced_name
FROM all_dependencies
WHERE referenced_owner = USER
AND referenced_type = 'TABLE'
AND type = 'VIEW');

Using a Database View and Untyped Dataset

Post Author: kramer9802
CA Forum: .NET
Product:Crystal Reports XI Release 2
Version:
Patches Applied:
Operating System(s):XP
Database(s):Oracle
Error Messages: Steps to Reproduce: Normally, the reports we create are designed based on Oracle tables. Then the data source is set to a dataset I populate in code from a SQL statement. I know this isn't necessarily how it is done in the documentation, but it has been working. What I am trying to do now is use a database view to design the report and then populate the my dataset based on a query on the view for VB code. When I do that my dataset only has one row, but my report is building based on all the rows returned by the view (Thousands). The sql is something like this Select * From xyz_view where record_id= ('The record the user wants to see') The view basically pulls back the data from several tables and also pulls back a few lookup tables that have description of value fields. I would use formula fields for the description but there is a lot records. I know that you can't pass a parameter into a view, so that is why I use select statement against the view to filter it down to the specific record I want. So I guess my question is why does build the report based on all the records from the view rather than all the one record in the Dataset? If I do the same thing but design the report based on a table or serveral tables, then the report only contains records from the dataset. I think I kind of know that the report is ignoring the dataset, but I guess I just need to know if there is an easy way to make this work or do I need to reconsider how I design and populate the reports. The reports are non-embedded based on a business requirement. let me know if this doesn't make sense or you need more details. Thanks Kramer

Honestly I do not know.
This question is more of a design issue and would be better suited to Crystal Reports forum
http://technicalsupport.businessobjects.com/cs/forums/13/ShowForum.aspx
As an aside, technically speaking if you are using datasets then you should be designing the report against the schema of the dataset you are going to be passing, not the tables or storeprocs or views themselves.

Polymorphic Entity Object on Database View ?

Hi all,
We want to implement polymorphism on business components (EO, VO). I have some questions :
1) On the supertype-subtype, is it better to use ONE table for all subtypes , or using different tables with each subtype ?
2) Is it recommended to use Entity Object on a Database View + Instead Of Trigger ?
Thank you very much,
xtanto

Our recommendation is in the ADF Developer's Guide for Forms/4GL Developers, in section 26.6 "Using Inheritance in Your Business Domain Layer". A single table is the simplest and most functional.
There's nothing wrong with using a view with instead-of triggers, as long as your not wasting your time to write PL/SQL that would be duplicating what ADF BC could automatically do for you using join view objects, with multiple entity usages, against multiple underlying tables. In general, you don't need to use views with instead-of triggers. See section 26.5 "Basing an Entity Object on a Join View or Remote DBLink" if you do.

SQL queries against a database view from an external system?

Hi,
I have a question about Database views in se11.
Is it possible to create a database view and that do SQL queries against this view from an
external system, Not a SAP system?
Please, I need you help.
Best Regards
Annika

Hi Annika,
it is possible , yes... but depends on your database systems in the SAP source DB and the external DB
(easier if they are the same, i.e. both ORACLE) - check out with your BASIS team (they have to create something like a "database link" in the external DB system that you can use to access the tables in the SAP source).
In the external DB you sure can create a view on these "remote" tables.
We used this to pull data form SAP DB to another DB system (both ORACLE based).
But this is NOT supported by SAP , so be carefull. Below is the restriction for ORACLE (as well for other DB systems )
see SAP note 581312 "Oracle database: licensing restrictions"
As of point 3, it follows that direct access to the Oracle database is
only allowed for tools from the areas of system administration and
monitoring. If other software is used, the following actions, among
other things, are therefore forbidden at database level:
* Querying/changing/creating data in the database
* Using ODBC or other SAP external access methods
This means that additional application software is only allowed if this
accesses the database through SAP interfaces (for example, RFC, SAP J2EE
or BAPI).
I would say if you KNOW the tables involved (using valid WHERE conditions and joins )
and don't start queries from hell (ad-hoc type) wich can bring down your SAP system performance
you can try it.
But be warned...
good luck...
bye

Database View do not refresh in ADF application

Greetings,
im facing a weird problem in my application (JDeveloper 11.1.2.4.0 - ADF). All this time i was working directly with tables (VO), but now i also started using database views.
Everything works fine, when i add a new row in a table that my Database Views is associated with, it refresh properly.
BUT if i delete rows manually from my database, the View do not refresh in my application, not by refreshing the page,
redeploying application, even executing the view object query inside the view object. The only way for the DB View to be
refresh inside the JDeveloper and on deployment time is by restart JDeveloper. I try adding an action on my OV to re-execute them when
i do something specifically, hopefully the will reset the cache and retrieve the DB view again, but with no luck..
Correction: now it doesnt even refresh on restart jdeveloper.
Just for the clarification, im talking about Database Views, and not just Object Views. I create a Object View inside the application to retrieve the data
from the Database View results.
Can you help me on this please?

Yes the queries in SQLDeveloper was showing me correct results.
But i feel disappointed.. When i went to close SQLDeveloper to try something, it pop me a message to commit/rollback changes.
After i commit them, my app show correct results too.

Set operator NE in Database View creation in join condition

Hi Experts,
I have a requirement to set NE(not equal) operator in join condition of Database View creation. Could you please help me how to set in operator.
Join condition :
Ex : BSAK-AUGBL NE BSAK-BELNR.
You know that by default operator is '='. i want to set NE in place of '='.
Thanks,

Hi Chinna,
Check whether if there is any possibility or not to include more key fields like bukrs, lifnr, gjahr etc in the where condition, so that you query may result faster. Then, there won't be any necessary to create the view.
Hope this helps.
Please reward if useful.
Thanks,
Srinivasa
