Doubts about performance:

Doubts about performance:
Hi:
In my work we have performance problems with the database (Oracle 9i v. 2), we have said that the TOAD consumes a lot of resources.
I know how to affect the performance of the database using a tool such as the toad.. ?
It is true that the use of inner join and left join instead of = and (+) is better?
Thanks

This is too broad a question.
Toad can fire random sql.
sql*plus can fire random sql.
Why would Toad be the problem?
You would need to gather statspack data to demonstrate this.
Sybrand,
Agreed on it and its a relevant point.But I guess he is not worried about the db performance.Anyways lets see what OP says.
Inner join and left join will always use CBO (Cost Based Optimizer) instead of RBO.
I am not sure that I have read that anywhere. They came into Oracle in 9i where optimizer mode was choose as the default one. Just by the syntax, oracle would push them to use CBO as the default one,I am not sure about this. Even if we are having + symbol and have the stats,Oracle wold go for CBO right?Can you please point me to some where in the docs where it is mentioned that using this keywords,Oracle would use only CBO?

Doubt about uses of OBIEE

I have some doubts about the possible uses of OBIEE. It happens that using OBIEE sometimes users demand report of an "analytical" type, that is aggregated analysis through OBIEE’s Answers, selecting data from dimension tables and measures from fact tables. That’s the ordinary purpose of business intelligence tools!!!
Some other times though, users demand to perform through Answers analyses of an "operating" type, that is simple extractions of some fields belonging to dimension tables, linked between each other through joins, (hence without querying fact tables): that happens because some of the tables brought in the datawarehouse are not directly linked to any fact table. In this way users want to use Answers to visualize data even for this kind of extractions (or operating reports).
Is this a correct use of the tool or is it just a “twisted” way of using it, always leading eventually to incorrect extractions? If that’s the case, is it possible to use instead BI Publisher, extracting the dataset through the "Sql Query" mode in a visual manner? The problem of the latter solution, in my case, relies in the fact that users are not enough skilled from the technical point of view: they would prefer to use Answers for every extraction, belonging both to the first type (aggregations) and the second one (extractions), that I just described. Can you suggest a methodology to clarify this situation?

Hi,
I understand your point... But I think OBIEE doesn't allow having dimension "on their own", they must be joined to a fact table somehow. This way, when you do a query in answers using fields of two dimension tables a fact table should be always involved. When dimensions are conformed, several fact tables may be used, and OBIEE uses the "best" one in terms of performance. However, there are some tricks that you can do to make sure a particular fact table is used, like using the "implicit fact column" in the presentation layer.
So back to your point, using OBIEE for "operational" reporting as you call it is a valid option in my experience, but you have to make sure that the underlaying star schema supports the logic that your end users expect when they use just dimension fields.

Doubt about the sizing in the CPH

Hi gurus!
I have the following doubt about the sizing in the CPH. I'm going to implement the CCMS BI CONTENT, i read the Note 979581 - Installing and configuring the CCMS BI Content, but in the document called "IT Performance Reporting Using SAP NetWeaver Business Intelligence" you can see images in this link:
http://www.servidor-imagenes.com/show-image.php?id=050236bd91654e16c94a559350611dff
here said how I can calculate the sizing based in Data Record Size per each Metric stored, but in specific, about the example: 20 systems, 17 CPH metrics. are included SCM, BI, ECC, SOLMAN in this 20 systems? And about the 17 CPH Metrics is talking about ratios? what's mean the CPH metrics?, How can I know what is my CPH metrics?
I hope can help me

Doubtful about security of oracle's Wrap code!

Dears
I am little bit doubtful about security of oracle's own Wrap code like package "sys.utl_smtp" .
Someone can easily Unwrap it without source code?
How it possible? whats your opinion about this? please can anybody clear me.
Regards
Abdul Halim
Edited by: Abdul Halim on May 31, 2013 8:14 PM

Halm, you are operating under the mistaken belief that your code deserves hiding from the customer and competitors to begin with. Why? All you are doing in the code is performing DML. It is not like your application is the only one in the world that performs its function.
If someone really wanted to they could figure out what your code is basically doing just by looking at the table and file data before and after running the code. By careful manipulation of the data and studying the results they can figure out what is being done and then develop their own specific of the how it is done. One can also look at Oracle's internals as the code is being processed both using Oracle provided views and direct peaking at Oracle's shared memory. Then there are tools like sql trace which will captute the SQL, waits, and binds for the process.
But all of this is kind of mute in that most shops do not have the talent to write their own unwrapper nor has the shop purchased an unwrapper so if you wrap the code it is going to be secured from most users and competitiors. I would just recommend that potential customers not purchase your product becuase the customer is going to need access to the code either for debugging (bugs will exist in the code) or tuning. Likely both.

Doubt about a null value assigned to a String variable

Hi,
I have a doubt about a behavior when assigning a null value to a string variable and then seeing the output, the code is the next one:
public static void main(String[] args) {
        String total = null;
        System.out.println(total);
        total = total+"one";
        System.out.println(total);
}the doubt comes when i see the output, the output i get is this:
null
nulloneA variable with null value means it does not contains a reference to an object in memory, so the question is why the null is printed when i concatenate the total variable which has a null value with the string "one".
Is the null value converted to string ??
Please clarify
Regards and thanks!
Carlos

null is a keyword to inform compiler that the reference contain nothingNo. 'null' is not a keyword, it is a literal. Beyond that the compiler doesn't care. It has a runtime value as well.
total contains null value means it does not have memory,No, it means it refers to nothing, as opposed to referring to an object.
for representation purpose it contain "null"No. println(String) has special behaviour if the argument is null. This is documented and has already been described above. Your handwaving about 'for representation purpose' is meaningless. The compiler and the JVM don't know the purpose of the code.
e.g. this keyword shows a hash value instead of memory addressNo it doesn't: it depends entirely on the actual class of the object referred to by 'this', and specifically what its toString() method does.
similarly "total" maps null as a literal.Completely meaningless. "total" doesn't 'map' anything, it is just a literal. The behaviour you describe is a property of the string concatenation operator, not of string literals.
I hope you can understand this.Nobody could understand it. It is compete nonsense. The correct answer has already been given. Please read the thread before you contribute.

Is there a way to view Flash videos on my iMac without downloading Adobe Flash Player? I'm concerned about performance and security with Adobe Flash Player.

If the video is only available in a format that requires Flash player : then no.
However, a great many can also be viewed in an HTML5 version, in which case http://hoyois.github.io/safariextensions/clicktoplugin/ or similar can be set up so that Flash never runs unless you specifically choose it to.

Doubt about Select statement.

Hi folks!!
             I have a few doubts about the select statements, it may be a silly things but its useful for me.
what is   difference between below statment.
1)SELECT * FROM TABLE.
2)SELECT SINGLE * FROM TABLE
3)SELECT SINGLE FROM TABLE.
Hope i will get answer,thanks in advance.
Regards
Richie..

Hi,
try this and if possible use sap help.i mean place the cursor on select and press F1.
             Types of select statements:
1.     select * from ztxlfa1 into table it.
             This is simple select statement to fetch all the data of db table into internal table it.
   2.   select * from ztxlfa1 into table it where lifnr between 'V2' and 'V5'.
        Thisis using where condition between v2 and v5.
4. select * from ztxlfa1 where land1 = 'DE'. "row goes into default table work Area
5. select lifnr land1 from ztxlfa1
        into corresponding fields of it   "notice 'table' is omitted
         where land1 = 'DE'.
          append it.
           endselect.
     Now data will go into work area. and then u will add it to internal table by
        append statement.
6.   Table 13.2 contains a list of the various forms of select as it is used with internal tables and their relative efficiency. They are in descending order of most-to-least efficient.

ENDSELECT.
SELECT BUTXT   FROM T001 INTO IT_T001 FOR ALL ENTRIES IN IT_EKKO WHERE BUKRS = IT_EKKO-BUKRS.
ENDSELECT.
APPEND IT_T001.
here I am using for all entries statement with select statement. Both joins and for all entries used to fetch the data on condition but for all entries is the best one.

Your code implements some business transaction, right? So if you commit before whole trancaction (from business standpoint) is complete other sessions will already see changes that are (from business standpoint) incomplete. Also, what if rest of trancaction (from business standpoint) fails?

Information about Performance manager's APIs

Hi All, I require some information about Performance Manager of Business Objects XI R2. Business Objects provides APIs for BOE server, Web Services for customization, as that of, is there any APIs available for Performance Manager (for customization)? Can we customize the performance Manager as per requirements? Please let me know your views & finding on this topic. Thanks

Hi John, From the output you shared it looks like you using Performance Advisor and want to share a graph of a 7-mode system. The instructions link you shared is from Performance Manager which is for Clustered Data ONTAP only. In the Performance Advisor there is unfortunately no way to share a link. You can 'save as' to png as you probably already saw, or you can use the dfm CLI to generate the same and email, perhaps as a daily report. There is also a data collector that will post to the NetApp ToolChest that submits data to Graphite with dashboards in Grafana. This solution would allow sharing of a URL like you desire. If you want more info on this let me know. Kind Regards,Chris MaddenStorage Architect, NetApp

Doubts about BP number in SRM and SUS

Hello everyone,
I have some doubts about the BP number, especially for Vendors.
I am working with the implementation of SRM 5.0 with SUS in an extended classic scenario. We will use one server for SRM and other for SUS. We will use the self registration for vendor (in SUS). My questions are:
- Can I have the same BP number in SRM and SUS?? Or is it going to be different??
- When a vendor accesses at the site to make a self registration in SUS, the information is sent to SRM as prospect (by XI) and there the prospect is changed as vendor? After that, is it necessary to send something from SRM to SUS again? (to change the prospect to vendor)
- When is it necessary to replicate vendors from SRM to SUS??
Thanks
Ivá

Dear Ivan,
Here is answer to all your questions. Follow these steps for ROS configuration:
Pls note:
1. No need to have seperate clients for ROS and SUS. Create two clients for EBP and (SUS+ROS).
2. No need of XI to transfer new registered vendor from ROS to EBP
Steps to configure scenario:
1. Make entries in SPRO --> "Define backend system" on both clients.
    You will ahev specify logical systems of both the clients (ROS as well as EBP)
2. Create RFCs on both clients to communicate with each other
3. In ROS client create Service User for supplier registration service with roles:
    SAP_EC_BBP_CREATEUSER
    SAP_EC_BBP_CREATEVENDOR
    Grant u201CS_A.SCONu201D profile to the user.
4. Maintain service user in u201CLogon Datau201D tab of service : ros_self_reg in ROS client
5. Create Purchasing and vendor Organizational Structure in EBP client and maintain necessary
    attributes. create vendor org structure in ROS client
6. Create your ROS registration questionnaires and assign to product categories- in ROS client
7. To transfer suppliers from registration system to EBP/Bidding system, Supplier pre-screening has to be
    defined as supplier directory in SRM server - EBP client.
    Maintain your prescreen catalog in IMG --> Supplier Relationship Management u2192 SRM Server u2192
    Master Data u2192 Define External Web Services (Catalogs, Vendor Lists etc.)
8. Maintain this catalog Id in purchasing org structure under attribure "CAT" - in EBP client
9. Modify purchaser role in EBP client:
    Open node for u201CROS_PRESCREENu201D and maintain parameter "sap-client" and ROS client number
10.Maintain organizational data in make settings for business partner
Supplier Relationship Management -> Supplier Self-Services -> Master Data -> Make Settings for the Business Partners. This information is actually getting getting stored in table BBP_MARKETP_INFO.
11. Using manage Business partner node with purchasers login (BBPMAININT), newly registsred vendors are pulled from Pre-screen catalog and BP is created in EBP client. If you you have SUS scenario, ensure to maintain "portal vendor" role here.
I hope this clarifies all your doubts.
Pls reward points for helpful answers
Regards,
Prashant

Doubts about use of REPORTS_SERVERMAP with Forms11g HA

Hi,
I'm configuring a Linux 64bits Forms/Reports 11g HA environment, the point is that i have two nodes, each one with its Forms and Reports servers, let's say FormsA and ReportsA for the first node and FormsB and ReportsB for the seconde node.
i want FormsA to be able to call reports from ReportsB and FormsB to be able to call reports from ReportsA.
I've been reading about REPORT_SERVERMAP
http://docs.oracle.com/cd/E12839_01/bi.1111/b32121/pbr_conf003.htm#autoId5
But i have some doubts about its use:
1. I will not use a shared cluster file system or any way of cache solution, i will only have my rdf files on each node, and i'm wondering if just by configuring this parameter i will be able to get the effect mentioned above ??
2. The link provided says "Using RUN_REPORT_OBJECT. If the call specifies a Reports Server cluster name instead of a Reports Server name, the REPORTS_SERVERMAP environment variable must be set in the Oracle Forms Services default.env file"
In fact i'm using RUN_REPORT_OBJECT but
what is the Reports Server cluster name ?? and where do i find that name ??
3. Is this configuration well defined:
REPORTS_SERVERMAP=clusterReports:ReportsA;clusterReports:ReportsB
4. At forms applications when using RUN_REPORT_OBJECT, can i assume that the report server name will be the cluster name specified at the REPORTS_SERVERMAP ??
5. Which files should i modify rwservlet.properties or default.env ??
Hope you can help me :)
Regards
Carlos

Hi,
1. I will not use a shared cluster file system or any way of cache solution, i will only have my rdf files on each node, and i'm wondering if just by configuring this parameter i will be able to get the effect mentioned above ??
--> In such case what could go wrong is
Suppose Run_report_object executed jobs successfully to ReportsA
But web.show_document command for getjobid failed ( as ReportsA went down by this time)
--> You will not get the output shown ( though job was successful)
If shared cache was enabled, then Even if ReportsA is down, other cluster member ( say ReportsB)
will respond back to web.show_document.
Point 2,
--> Under HA is it highly recommended to use web.show_document ( a servlet call) to execute reports. This is to help use all HA features at the HTTP , Webcache or load balancer level.
However if there is migrated code or Run_report_object is must, then the recommendations as you see in the pointed document is must.
REPORTS_SERVERMAP setting needs to be configured in rwservlet.properties file and also in default.env Forms configuration file to map the Reports Server cluster name to the Reports Server running on the mid-tier where the Load Balancer forwarded the report request.
For example FormsA, ReportsA, cluster name say rep_cluster
default.env file
REPORTS_SERVERMAP=rep_cluster:ReportsA
Where "rep_cluster" is the Reports Server cluster name and "ReportsA" is the name of the Reports Server running on the same machine as FormsA
rwservlet.properties file
<reports_servermap>rep_cluster:ReportsA</reports_servermap>
At default.env this is not a valid entry
REPORTS_SERVERMAP=clusterReports:ReportsA;clusterReports:ReportsB
what is the Reports Server cluster name ?? and where do i find that name ??
--> This is created via EM on the report server side.
Would recommend to refer following documents at the myoracle support repository
How to Setup Reports HA (High Availability - Clusters) in Reports 11g [ID 853436.1]
REP-52251 and REP-56033 Errors When Calling Reports From Forms With RUN_REPORT_OBJECT Against a Reports Cluster in 11g. [ID 1074804.1]

Doubt about proxies implementation

hi experts i have small doubt about proxies implementation
1. if we r implementing client proxies, it means sap r/3(proxy)->>xi->>>file
     system.here where we have to execute the SPROXY transaction. in sap r/3 or
     in the xi server.and the next thing is where we have to write the report program
     to trigger the interface.in sap r/3 or in the xi server.
2. if we r implementing server proxies, it means File->>xi->>>sap r/3
    (proxy).here where we have to execute the SPROXY transaction. in sap r/3 or
     in the xi server.
please clear me
Regards
giri

Sreeram,
The Integration Server and the client on which you generate the proxies should not be the same. If they are different then yes, you can use another client in your XI box itself to generate proxies and trigger the call to XI.
If you see this blog by Ravi ( incidentally he is my boss as well ) this is exactly what we have done as well.
/people/ravikumar.allampallam/blog/2005/03/14/abap-proxies-in-xiclient-proxy
When you say XI, you mean the Client on which the Integration Server is running! XI is basically a R3 instance with more functionality and its own Integration Engine.

Doubt about unicode conversion

Dear Friends,
I have a doubt about the unicode conversion. I have read (one server strategy) that I have to do export (R3load), delete the ECC 6.0 non-unicode, install an unicode database and then import with R3load. My doubt is about the deletion of ECC 6.0 non unicode. Why? can I convert to unicode only with an export (R3load) and subsequent import (R3load) without any deletion?. Obviously I must to change the SAP kernel with a unicode one. Is it correct?
Cheers

you can not convert a SAP System to unicode by just exchanging the executables from non unicode to unicode ones.
a non unicode SAP Oracle database is typically running with a database codepage WE8DEC or US7ASCII (well this one is out of support).
so every string stored in the database is stored using this codepages or SAP-Internal codepages.
When converting to unicode you have to convert also the contents of the database to unicode. As unicode implementation starts at a time where Oracle did not support mixed codepage databases (one tablespace codepage WE8DEC the other one UTF8) inplace conversions are not possible. To keep things simpler, we still do not support mixed codepage databases.
Therefore you have to export the contents of your database and import it to a newly created database with a different codepage if you want to migrate to unicode.

Peter

Doubt about Patch

Hi everyone!
I have a doubt about applying patch.
I just applied this patch (using GUI):
Oracle® Database Patch Set Notes
*10g Release 2 (10.2.0.4) Patch Set 3 for Microsoft Windows (32-Bit)*
Initially, there was an error stating that some other process is accessing one particular dll.
I ignored it.
I rerun the patch installation thinking that I need to get that dll as well.
It gave a list of what has been installed and what can be installed.
So, I selected all the remainders and installed.
It was successful. Now, would it have ignored that dll or installed it?
Please advice.
Thanks in advance.
Cheers!

You can't ignore any dll related errors. If a dll is in use, oracle patching process will not replace that with a newer version of dll. I'll strongly recommend the use of ' Microsoft Process Monitor' utility to monitor, what is running on my server.
