Output for front end

Hi,
I've attended an interview on SQL and PL/SQL yesterday. Being a fresher I prepared only basic concepts. But I was posted a question regarding output for the front end application. The question is
"I'm having an exception in a function from a package. Now I can get that in backend using dbms_output.put_line. Tell me how the front end guy will come to know about the error/exception"
Please answer me

>
"I'm having an exception in a function from a package. Now I can get that in backend using dbms_output.put_line. Tell me how the front end guy will come to know about the error/exception"
>
Your question isn't clear.
You can't get the exception in the back end using dbms_output unless you have an exception handler in the function. Then you can use dbms_output to capture the error code and message and use put_line to write it to a buffer.
It is up to the code calling the function to request the text from the buffer.
If you asking how a tool like sql*plus can get the dbms_output text then use SET SERVEROUTPUT ON and when the package function completes all DBMS_OUTPUT text will display.

3 Must have features for front-end developers

I'm a front-end developer, so these requests are more or less specific to my job.
Selecting an entire layer
Currently: If you do a "ctrl-click" on a layer, it selects the layer. However, if you have filters or effects applied to the layer, it does not select those.
The Problem: Since I cannot select the filters/effects, I have to zoom in on say a button with a drop shadow. I've been using png's heavily in my sites these days, and I want the drop shadow to be on a transparent background. It's difficult to zoom in and find the end of the drop shadow. You can change the transparency grid colors to help out, but it's still difficult and more importantly tedious and time consuming.
What I want: I would like the ability to select everything on a layer by doing a "shift-ctrl-click" or something. That way if I make a button with a drop shadow, I can select the button and the filters/effects that are applied to it. This would also give me the correct size of the layer as well, which is helpful information to me during html/css layout.
Organizing Groups/Layers
Currently: You can create groups from layers, or create a group then drag the layer into the group.
The Problem: When a PSD starts to get alot of layer/groups, it gets difficult to organize. If I create a new layer, or duplicate a layer group, my next step is to drag that group or layer into the proper group. My PSDs get very long, especially on homepage comps. I have to scroll up and down in the layers window to hunt for my group. Once I find the group I have to drag my new layers into it. This is annoying and clumsy.
What I want: I want to simply right-click on any layer, group, selected layers, or linked layers and in the right click menu, there should be a "send to" option. The send to should have a tree of the current groups. Then just choose the group you want and the layers/groups etc move there.
This will save me alot of time especially since my designers are lazy and don't organize things properly.
Copying layers/groups to other documents
Currently: To copy a layer/group from one file to another you have to take your files out of tab mode, then select, click and drag the layers/groups from one document to another.
The Problem: I really enjoy tab mode, and it seems pointless to have to drag the layers/groups from one file to another. There needs to be more ways to accomplish this.
What I want: I want to stay in tab mode, select my layers/groups and drag them to the tab I want to copy them to. So if I select a button, I should be able to simply drag it to another open file tab and it should copy those layers/groups to that file. Or another option would be to right click on the selected layers/group and do a have a "copy to" option where you can select another open document to send the layers/groups to.

You can "send" layers & groups to another document with duplicate to the target document. Simply right-click the source layers in the Layers panel, choose Duplicate Layer...
and in Destination, select the target document. No un-docking and dragging.

Multiple PDF outputs from front-end

I am working on a report that always shows one page per customer. When user generates report from front-end interface, this will call BI Publisher report and report shows entire customers information in one PDF (with X pages for X customers). Users want to see X number of PDF documents with each PDF having 1 page for customer when this report is invoked on demand from a front-end application. Is this possible in BI Publisher?
I know there is bursting functionality, but it is applicable to scheduled jobs.
Please could some one help me to figure out if this is possbile in BI Publisher or not.
Many thanks in advance.

Need a power shell command for Front End fail over?

We have a Lync 2013 infrastructure with 2 front ends and 2 edges.
The environment was setup by a partner and the servers were configured for failover in case one goes down in the pool.
However the last time windows updates were applied and the primary FE had to be restarted, the secondary FE did not automatically switch over as the active server and it caused a companywide outage.
In speaking with the contractor, they said that well no it would not automatically do this, you need to run a Lync PowerShell to have it switch over.
My BS radar went off, but I wanted to ask you if this sounds right or is possible.
If it must be done, could you give me the power shell command.
Thanks

Hi,
Did you solve the issue with the help of the people above provided?
If you use a Lync server Enterprise edition, it is recommended to deploy at least three FE servers.
If you use two Lync server Standard edition for DR,
when one of the servers fails in the Pool Pair, the administrator need to manually failover the pool to the other member of the Pool Pair using the
command: Invoke-CsPoolFailover -PoolFQDN <Pool1 FQDN> -DisasterMode -Verbose
The Automatic failover and failback for
Voice option and the associated time intervals in Topology Builder apply only to the voice resiliency features that were introduced in Lync Server 2010. Selecting this option does not imply that the pool failover discussed in this document is automatic.
Pool failover and failback always require an administrator to manually invoke the failover and failback.
You can refer to the link below about how to failover a pool:

Does it help, yes and no. FYI, we are running Enterprise Edition front ends for our single pool. The new environment was setup as a proof of concept and we installed the bare minimum # of servers at the time.
The articles suggested from above pretty much just say if one of your FE's goes down, bring it back up as soon as possible. Both of our FE's need windows updates applied ASAP and it could an hour or more (likely). Here is a quote from the article:
If for some reason you need to bring both servers down at the same time, do the following when the downtime for the pool is finished:
The best practice is to restart both Front End Servers at the same time.
If the two servers cannot be restarted at the same time, you should bring them back up in the reverse order of the order they went down.
If you cannot bring them back up in that order, then use the following cmdlet before bringing the pool back up:
Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery -PoolFQDN <FQDN>
The last time the main FE went down for service, we left the secondary FE on but there was still an outage. Then brought back the formerly active FE fist and service was restored. Basically I need to know how to switch the passive to the active
node before/while the primary is offline. And if required once both FE's are back up, to switch the service from the secondary that became active, back to the primary server as it was before. Make sense? Perhaps I'm still missing something
after reading the articles. The powershell commands list just updating the topology after both servers come back online.

Appreciate your answers

Usually this means, that some necessary controls are not properly registered in the registry and hence can't be found. You may solve that by removing the SAPGUI from the PC completely, booting the machine and reinstall the GUI.

Front End Runtimes in BI workload are always 0

Hi,
We have activated the technical content for BI Admin cockpit in Production. The delta process chains are
running fine daily. The issue is we do not see the front end runtimes in BI workload via ST03N. Only for a very
few queries we have RSDDSTAT settings activated at level 2. BI workload displays only OLAP and DM times
for those queries. But the frontend times are always 0. We are extracting all the step categories. I can see
the front end runtimes for all those queries in 0TCT_C01, but they are not shown in BI workload. Hence even
the Total Time of the query in BI workload is always smaller as it does not include the front end runtimes.
Any idea why the data for front end runtimes is missing from BI workload ?
Thanks,
Sonali

Hi,
depending on your data flow you have to use the routines .
Start routines - start routines:
It is used to perform preliminary calculations.if you have any modifications required before the actual transformation is done, then you must write those routines in the start routine of 7.0.
End routines - new:
You can use an end routine to postprocess data after transformation on a package-by-package basis.
Expert routine - update routine :
You can use the expert routine if there are not sufficient functions to perform a transformation. The expert routine should be used as an interim solution until the necessary functions are available in the standard routine. You can use this to program the transformation yourself without using the available rule types. If you have already created transformation rules, the system deletes them once you have created an expert routine.
Also Check the below link for detail info.

Front End pool failed over

Hi all,
1. I setup a pool with three Front End servers (FQDN of pool is pool.site1.sip96x2.com and it's pointed to IP address of three Front End servers). Everything works fine. But When I disable network interface on FE1 and FE2, the Lync clients are disconnected.
I haven't understood clearly how the Lync clients failed over in a pool? Please clarify to me.
2. I have two central site (Root site and Primary site, they have different domain sip96x2.com and site1.sip96x2.com). The simple URL dialin is pointed to Front End server at Root site. So if the link between Root site and Primary site is down, how can the
users at Primary site connect to dialin URL?
3. In building topology for Front End pool, I checked Override FQDN internal web service and the FQDN is "poolint.site1.sip96x2.com". I created three A records "poolint.site1.sip96x2.com" and pointed to three IP addresses of Front End
servers. Is it right?
Thanks so much!

Ah ok, well first thing if I am reading this correctly, pool pairing Standard with Enterprise is not supported. You should only pair Standard with Standard and Enterprise with Enterprise (even though topology builder won't stop you) Take a look here for
support scenarios http://technet.microsoft.com/en-us/library/jj204697.aspx
To deal with the simple URLs in the event of failover you need to add them using Powershell. Take a look at this article which explains and gives an example: http://blogs.perficient.com/microsoft/2012/01/configuring-simple-urls-for-multiple-lync-pools/

hello all
i am facing problem in data carrier creation for front end computer. actually i am creating data carrier type PC and i want set as default for all desktop. After DEFINE DATA CARRIER TYPE SERVER, FRONT END and Select PC and IDENTIFY FRONT END COMPUTER its shows following error
No entries found that match selection criteria

You can make new entries independently of this. To do this, select the function New entries in menu Edit.
help me

Hi Vivek,
In the SAP standard this entry are maintained only by the system
itself and they cannot be entered manually in transaction DC20. I can
only provide you the following information on the possible settings for
variable HOSTNAME and the DEFAULT frontend entry.
1. Default entry
   Call transaction 'DC20'. Double-click node 'Define data carrier type
   "server, front end"'. Select the respective data carrier type (e.g.
   'PC') and double-click node 'Identify frontend computers'. Click
   button 'Default entry' in the top right corner of the table control.
   Note that it is only possible to create 1 default entry!
2. System variable HOSTNAME
   If you run Windows XP, please go to Start -> Settings -> Control
   Panel. Double-click on 'System'. Click on tab 'Advanced' and then on
   button 'Environment variables'. Create system variable 'hostname' and
   assign a value'. Save the new variable.
As there is already a DEFAULT entry for frontendtype 'PC' it cannot be
maintained for another frontend type.
Best regards,
Christoph

Monitor connected front end users

Hi ,
I have an application with access control list and table which holds application users / used for authorization etc ...
at the database level I would like to see and know which session belongs to which fron end users!
at the database level I can only see session id's and application's username which is htmldb_public_user.... and its unique for every user..
lookin at Utilities>Database Monitor>Sessions page I can only see one developer connected! but cant see session or session id for front end users? is there anyway to find out the session info for this user?
Thanks

its the same question with a diffrence that he is trying to have diffrent applications login as diffrent username so he can trace applications individually(which is what im intrested in too) where as im more intrested in knowing the session id for each front end users who are viewing/inserting or deleting data through the applications! hope this makes sense!
I dont undrestand below response!
Bill,
FYI, the engine does this for each database session:
begin dbms_application_info.set_client_info(g_user); dbms_session.set_identifier(substr(g_user,1,(64 - length(g_instance)-1))||':'||to_char(g_instance)); dbms_application_info.set_module('APEX:APPLICATION '||to_char(g_flow_id),'PAGE '||to_char(g_flow_step_id)); exception when others then null; end;
...where g_user is the authenticated user, g_flow_id is the application ID, g_flow_step_id is the page ID, and g_instance is the Application Express sessionID. I don't know where to tell you to look for these markers but they will be associated with the database sessions that you're seeing which are owned by APEX_PUBLIC_USER.
We are looking to move to a 4 RAC environment which is creating many questions concerning APEX architecture.
I've seen all your other posts about this and IMO, there are no questions to be answered about the architecture of Application Express vis-a-vis RAC, and vice versa.
Thanks

How to add front end material to your book?

Hello,
I have added all the chapters to my book and now I want to add the Title Page, Dedication, Acknowledgements, and Introduction pages before Chapter 1.
I thought these would be seperate sections at the same level as chapters, but everytime I add a section it inserts into chapter 1. Do I create a "Front End Material" chapter and then insert the sections? ("Front End Material" sounds so wrong for a chapter name)
Could someone please let me know the proper way to handle this. I also have a bibliography which I am also assuming is a seperate chapter at the end.
Thanks,
Rhek

Would you happen to know if there is a "formal" name for "front end" material?
Thanks,
Rhek
'Front Matter'. At least in English
Other cultures like to put an index in the front, as one example, so 'front' becomes a relative term.
Some like everything on the same level, so there is no 'front'. And still others like to bury the details in minutiae, leaving it to the reader to decode, often to the extent that they are left to come up with their own structure...or not.
