Front end Backend Modeling Configuration Reporting and Extraction.

Hi..All
Can Any one plz explain the terms "Front end","Back end" related to Modeling,Configuration,Reporting and Extraction.
Thanks & Regards

Hi,
Frontend is the reporting aspect, i.e Workbooks, queries, Web reporting, Crystal reports, etc.
Its called the frontend as that's what the users see and they don't see what goes on in the 'backend' i.e Config and Extraction, data manipulations, etc.
Modeling is used to design the cube, ODS, etc. Also modeling concepts can be used to design frontend queries as well.

What are the common errors in reporting and extraction.

hi friends,
what are the common errors in reporting and extraction for implementation and support projects.
thanking u
suneel.

Hi Suneel,
Errors in reporting are like incorrect query creation, errors in creating RKF, CKF and variables, misunderstanding the data, or errors with other tools like broadcasting. Errors in extraction relate to source system connectivity, field-infoobject mapping, incorrect code etc. Also, please search the forums and you will find many real time examples.
Hope this helps...

Does EBS license include tools for reporting and extracting data (queries)

Hello,
I'm recommending Oracle EBS to a customer and I need to mention what tools for reporting and extracting data (queries) are included in a Oracle EBS license.
I hope you can help me with that information, or at least with providing me the place where I can get the info.
Thanks in advance,
A/P Sergio Maestri

Hi,
Thanks, I think the same ... but the customer asked me about it ... I supose my answer will be that he can use Reports Builder for reporting and Toad or PLSQL Developer to access to the database and make queries ...
What about XML Publisher ? ...it can be used to make reports against an Oracle EBS database and integrate them into the EBS Application ?I believe you need a developer license to use Oracle Developer (Forms/Reports) for customizing/creating reports.

How do web front ends find the configuration database (moving whole farm to new AD forest)

We are exploring, as a possible course of action, moving our SharePoint 2007 medium farm to a different Active Directory forest (2008). There is a two way transitive trust between the source and target domains.
I have established that with such a trust it's possible to add content databases on a SQL instance in another forest, so moving content is not a big issue; we'd stand up new instances and move them: the user accounts are almost all in the target domain anyway.
However, we have a good deal of customization, including a third-party application that no longer has any support and has historically been appallingly difficult to upgrade/install fresh.
How do web front end servers find the SQL instance containing the configuration database? If the farm credentials had been previously changed to an account in the target domain, all services stopped and the configuration database moved to a new instance
with a DNS alias, would the database appear to be in the same location when SQL and SharePoint services were started on (logically) moved web front ends?

Here is more or less the high-level process for SharePoint 2007:
Mid- to high-level steps.
0. Full farm backup
1. Move users to new domain (in AD). Use stsadm -o migrateuser to migrate the old domain accounts to the new ones in SharePoint
2. Move service accounts to new domain, or create new service accounts
3. Update the farm to use the service accounts in the new domain
stsadm -o updatefarmcredentials (service accounts)
stsadm -o spsearch -farmserviceaccount
stsadm -o spsearch -farmcontentaccessaccount
stsadm -o editssp -ssplogin (for each ssp)
stsadm -o osearch -farmserviceaccount
SSO and any other remaining service accounts (CA -> Ops -> Service Accounts)
Default content access account (SSP -> Search Settings -> Default content access account)
Customizations (if there are service accounts associated with these)
3.5 Manual steps
Application pool accounts
Update permissions for SQL Logins to make sure the new accounts match the permissions for the old accounts
Add the appropriate new accounts to the DCOM IIS WAMREG Admin Service
4. Update the SQL Server service accounts. If SQL Server is shared with other applications you'll want to update the SQL Logins for these other applications as necessary and the SQL Server service accounts (DB Engine, DB Agent, Reporting Services, etc.). Might
not be necessary if this has already been done or if the SQL server is not changing domains.
5. Shut down all services on all servers in the farm (this includes SQL if you are moving to the new domain).
6. Change domain membership of all farm servers, reboot or perhaps shutdown and bring back up in the following order:
1. SQL. Verify SQL Server is running and accessible. Check event logs. Resolve any issues.
2. Central Admin server. Verify CA is accessible, check event logs. Web apps and some services may not be available if they are on servers that are currently turned off. Don't worry about these (yet).
3. Application servers, search servers, index, query, other. It's likely some or all of the WFEs will go on at this step. Verify services are accessible as expected. Check event logs. Resolve issues.
4. Any remaining WFEs. Wash, rinse, repeat.
7. Assuming everything is running as expected, users can access the sites, the sky did not fall, etc. take a full farm backup.
Hey look, here are some low-level steps too.
# updates the account used to run the CA app pool and the timer service
# must be run on the server that hosts CA
stsadm -o updatefarmcredentials -identitytype configurableid -userlogin NEWDOMAIN\farm_service_account -password Password123
# spsearch
stsadm -o spsearch -farmserviceaccount NEWDOMAIN\search_service_account -farmservicepassword Password123 -farmcontentaccessaccount NEWDOMAIN\crawl_service_account -farmcontentaccesspassword Password123
# osearch
stsadm -o osearch -farmcontactemail [email protected] -farmserviceaccount NEWDOMAIN\search_service_account -farmservicepassword Password123
# ssp service accounts
stsadm -o editssp -title SSP -ssplogin NEWDOMAIN\ssp_service_account -ssppassword Password123
# Manual steps
SSP Admin -> Search Settings -> Default Content Access Account
Application pools: CA -> Operations -> Service Accounts -> Web Application Pool (or use gl-updateapppoolaccount if available)
iisreset /noforce
Copy SQL permissions to the new accounts. Not sure why this doesn't happen.
SSP Service Account
Farm Account
Setup Account (not copied because it doesn't own anything, just used to kick off the DB for the other accounts)
Search Service
Add accounts to DCOM not sure why this didn't happen
Component Services -> Computer -> My Computer -> DCOM Config -> IIS WAMREG Service
Farm account
Application pool accounts
Search Service
SSP Service
SSP Admin
Then the fun part. Move the server into the new domain.
Check for AAMs to see if they reference the current domain. If so, change to the new one.
Stop all SP services. Join new domain.
The computer name is a netbios name in SP, this should be painless.
Some general notes from my experience doing this:
1. There is no way to update application pool identities with stsadm (I haven't explored using Powershell). You have to go through CA -> Service Accounts to update these.
2. Some SQL logins and permissions were not created. I compared the permissions before to the permissions after and copied the ones that didn't transfer. This resolved all database access issues.
3. Had to grant permissions for the service accounts in the DCOM configuration for the IIS WAMREG admin service. I expected this to happen automatically but was not surprised given the history of CLSID 61738644-F196-11D0-9953-00C04FD919C1.

Front End for BW 3.5 and Java based application

We are trying to connect two systems; SAP based (through BW) and Non-SAP based (Sybase, Java based) applications. We are exploring BI Java SDK with UDDI or XI services to bring Non-SAP data to NetWeaver. We don't want to store all data from sybase to BW. We could use Front end of BW or any other GUI from SAP Portal. I have heard options like UI, GUI machine, net weaver developer studio, visual composer. Ideally, we would like to combine non-sap and sap data in Business explorer/BW web browser but any other front end suggestion within Net weaver frame work will help us keep our cost down. Please advise.
Thanks.
Vinay Karna

We're in the middle of upgrading from 3.1 SP 22 BW w/6.20 SAPGUI. We've only upgraded a sandbox BW server at this point, but we have upgraded all BW team members with SAPGUI 6.40 FEP 5 and can successfully connect to our 3.5 and 3.1 BWs.

2 Front End Servers with reporting enabled in topology but only one server shows reports

Hi,
We have 2 Front End Standard pool servers with resiliency enabled between them. The monitoring service is configured in the topology so that both Front End Servers point to the same monitoring database. We have half our users homed on 1 Front
end and half the other users sitting on the other Front End. In the Reports we can only see information on Audio calls made from users that are sitting on our Primary Front End Pool Server however we cannot see call information from users that are sitting
on the other front end server?
Thanks, Kevin

We have applied the backend updates and verified the config by running Test-CSDatabases cmd-let . I ran enable-cstopology and ran bootstrapper.exe and rebooted both Front End Servers, however we are still unable to see monitoring data of users
homed on our second Lync Front End server.
Any other suggestions? Thanks for responses so far, appreciate the assistance!

How front end query invoke error message at backend

Dear all,
Please help me this out! I'm working on servlets(using Apache server). I'm sending sql statement to (dbaccess) database. If I do a sql statement directly at backend, the db will generate an error message. Now I'm sending the query at front end. When error occurs, the backend doesn't show the error message. I have no idea how to 1) generate the error messages at backend when a sql from front end is executed. 2) And then how the backend send the error message to the frontend.
If you have any idea, please help me. I greatly appreciate that!
Regards,
Grace

Thanks. Backend means database. But I just wonder why this exception not shown on my webpage. I made it to print out in html file.
And are you sure that the exception front end caught is the same error message that I get if I run the sql statement at backend directly? Because I'm thinking of ways to make the error message both detail and user friendly to understand.
What would you think?
Thanks again!
Grace

Regarding connection between front end HTML and back end SQL 7.0

Hi!!
I am working on the project 'ERM'. I have designed 12 forms using HTML. Can u please give me brief idea how to establish the connection between a back end and front end i.e. between HTML and SQL 7.0. If possible can u provide me the source code for the same.
I will be very thankful to you.
Thanks,

You need servlet and JSPs for the server-side presentation layer, some classes for the business logic, and some mor for the persistence layer either using JDBC or some framework like Hibernate.

Lync 2013 Enterprise load balancing on the front end and edge pool

Hi,
I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers). I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers. I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
balance my front end pool. I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
Can someone clarify the front end requirement?
Also - looking now at the edge pool - this site again have two edge servers in a pool. We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com). These will be
NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443. I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
Persevere, Persevere, Per..

That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
The description on the calculation tool also describes this correctly:
Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
Lync web services)
You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices. Both are applicable for the Front-End so you have either
full HLB for both SIP and HTTP(S) traffic
DNS LB for SIP traffic and HLB for HTTP(S) traffic
Hope this is more clear :-)

How to implement Oracle user/role security with Access front end?

Hi,
We have successfully migrated our Access database tables to Oracle 10g using SQL developer. We've recreated all the users and roles(i.e., access groups) in Oracle and granted rights to tables.
In the Access front end database, in the Database window we have saved linked Oracle tables which replaced the Access tables. The forms, reports, queries run fine with the linked Oracle tables. All the linked table use one ODBC DSN to the Oracle database with the same Oracle user id.
We need to be able to authenticate users into the Oracle database and RE-link the tables based on their own unique user id. By during so we can allow users to use the Oracle standard user id/role and system privileges to control select, update, ect. rights to the database.
I've been able to use the VB code within Access to logon into the database with a unique id, but I have not been able to find out how to RE-link the tables to the unique user id using VB. There should be some way to relink tables dynamically, based on users login into the Access front end.
I don't know a great deal about Access projects, but I do know with SQL server allows login into your Access project and link tables dynamically.
Can someone give me some assistance or point me in the right direction?
Thanks in advance,
Larry

We had one of our programmers here come up with a VB code solution for re-linking table within Access. However the relinking takes 3-4 minutes for 100+ tables.
In an effort to help you understand the situation better, I will attempt to elaborate on the problem:
We have an Access 2003 application which currently has a front end using Access(forms, reports, queries, & VB code) and a MS Access 2003 backend.
We have migrated the backend tables to Oracle. However, we still have a need to maintain the front end in Access, since we have over 60 forms, 40 reports, 200+ queries in Access. Its easy to understand, we have a significant investment in the front end(Obviously, the plan is to migrate the front end also at some future date).
In order to utilized the existing front end, we have to validate and modify the current front end connections to the new Oracle backend. One of the features of Access is that you can "link" tables and save the link for runtime. Each Access table can have its own link which is a separate ODBC/JET connection. As such, each separate link has its own userid/database information.
The other issue with using the Access front-end is that Access utilizes a workgroup file to implement user and group security. The workgroup file contains all the users and which groups the users belong to in Access. Then within Access, you allow users access to object(tables, queries, ect) by their userid and or group. When users open an Access database with Access security enabled, they are required to log into Access. The login is authenticated by the workgroup file. Once, logged into Access, users have rights to Access objects based on their rights granted to their userid and groups they belong. The problem here is that when you remove the linked Access tables and replace them with linked Oracle tables, Access has knowledge about Oracle table rights granted to users; nor would you expect it to.
The dilema is the disconnect between Access and the fact Oracle utilizes a similar but much more sophisticated security model. It creates users and roles(which are similar to Access groups), and again this is independent of Access security.
Our solution was to still use the Access workgroup file security along with the Oracle security model. By using the Access userid and then creating a similar Oracle userid with similar table rights granted in Access, you could apply security within Access and also with the Oracle database.
For example, a user BOB logs into Access via the workgroup file, using VB code, Access then establishes a Oracle connection logining into Oracle using the same unique userid BOB into Oracle.
After connecting and validating user BOB into Oracle, then the Access tables are relinked to Oracle using the user BOB userid and table rights.
This Oracle userid has been granted table rights specific for this userid.This allows the user BOB to use the Access application and still be authenticated into the Oracle database.
The problem with this solution is that the relinking of the saved Access tables takes 3-7 minutes for about 100+ tables. This is not acceptable for users each time they log into the application.
Our current alternative is to use one Oracle userid to login each user, and use Access form restrictions/security to allow/prevent users from updating/viewing data. Obviously, this is not the optimal solution in respect to security, but it at least allows us to control access to the data(via the forms) by using one logon required for each user, and quick startup time for the application.
I understand SQL server does a better job in integration, but we use Oracle which is what I am trying to work with.

          No. I was splitting presentation logic (namely servlets and jsp) and business
          logic (ejb) into two layers. Again you don't have to split it into two. You can
          colocate them both together. You could use NES or IIS or Apache or WLS. You
          don't need HttpClusterServlet.
          Lets get this straight.
          1. You need our proxy plugin for failover and to load balance the request that
          are going to presentation logic.
          2. From presentation logic layer, when you talk to backend business logic
          providers (like ejb cluster), if you use stateless session beans we provide
          failover and load balancing. In future we will support clustered stateful
          session beans as well. Therefore you don't need load balancer here.
          3. HttpClusterServlet should run only in front of presentation logic cluster and
          also it supports http only.
          Hope this helps.

I have a simple SharePoint environment with a SharePoint 2010 front end and a dedicated SQL back-end. Both virtualized on Hyper-V 2008 R2 host. There are no complicated apps - it is just a file serving SharePoint implementation.
The VHD for the front end server (it only had one drive) got corrupted. I have an export of the complete server from the 29th December, including the VHD.
The back end (SQL and all the databases) if unaffected.
I tried creating a new VM with the three day old VHD from the export, but it does not seem to correctly connect to the back end.
I also have DPM 2012 backups of the whole thing systems, though they are made via the SharePoint front end.
With a whole panoply of solutions I can:
1. import the exported front end and see if that works better than just re-creating the machine (GUIDs and all that)
2. Forget the export of the front end on the 29th and do a fully fledged DR from DPM
Any other ideas?

One thing to note is that SharePoint does not support VM backups (that is, snapshots or full backups of the VHD itself). Since your VHD is older than the data within the Configuration database, it is best to start with a new front end.
You should be able to install SharePoint up to the same patch level on the new front end, "join" the existing farm, and then forcibly remove the defunct SharePoint server from Central Administration.

Maximum number of users per Front End, assuming no AV

I know that MS recommends 80,000 user limit per pool, and 6000 per Front End server, but that's certainly going to be assuming you are using the Front End services to some degree.
A/V, I'm certain, is a fair overhead. Is there any kind of idea what the user limit per Front End server is if we assume the Front End is *only* doing IM and Presence?

Using the capacity planner at a server built out with full specs, it's still suggesting 6600. Without Mobility, 7200.
Microsoft doesn't publish more than that so the rest is an at your own risk. If you have enough users that it would be a concern, I'd just stick within the supported models. You could start low and scale up by adding a front end or start
high by removing a front end.
