How to run the processRequest initialization only once

My home page has a table that is initially populated based on the users userId.
The user can then select a differnt user to display data for.
From the table, the user can drill down to another page. If the user uses the browser back button (need to press twice), he is returned to the search results correctly.
If instead the user clicks on the returnNavigation link, the query initialization in the processRequest is fired again.
Is there a way to only fire this query initialization when the page is first loaded ?
Similiar type of problem where I set the pagetitle to a parameter passed from the original page. If the user then drills to a 3rd page and returns using the returnNavigation link, the data is still the same but the page title (set in the processRequest section) is set to null

Well, first thing is that issue subject is kind of misleading. You cannot have control over the inherent calls to processRequest but what is required is putting up some logic to overcome your issues.
You can maintain a session flag to track your status of first time page load. With the help of this flag, you can conditionally initialize the query. Same applies to page title issue.
One more suggestion, never use browser back button.

(BW) Run the Start Routine Only Once

I understand that for every data package from ODS to Cube, the start routine is run. But I need to run it only once. Is there anyway to achieve this in ABAP?

I once had that same requirement, but in a datasource in R3. I'm not sure if the same solution would work in BW, though. I used a memory id to keep the variable value between packets:
DATA: ... n_globalvar TYPE n ...
then I added...
IMPORT n_globalvar FROM MEMORY ID 'ZMEMID01'.
...at the start of the routine to retrieve to the variable the value from the memory id.
At the end of the code, I exported the variable back to the same memory id...
EXPORT n_globalvar to MEMORY ID 'ZMEMID01'.

How to run the form that is only installed on a PC and not using a server?

Hi
I am new to Oracle and have taken the forms class. But I do not understand how to run the form from my PC using XP windows. (Do not have access to a server).
I have started the OC4J, made sure the listener was started, compiled the form and then when I run it, it automatically goes to the HTTP:
ERROR: res://ieframe.dll/acr_depnx_error.htm#,http://kevin:8889/forms/frmservle
I connected to the database correctly. I can process a report and it does nor try to access the internet. My only issue is running the form. I verified it compiled.
Sorry for a basic question. Could someone please help, I tried reviewing other questions, but not sure if they are connecting to a server or not.
I see webutil but is it required if I don't have a server? Thank you in advance.

Regardless of the version, it appears that you may not have configured the Builder. Do the following:
1. Open the Builder
2. From the menu, select Edit > Preferences > Runtime
3. In the box labeled "Application Server URL:", enter a local URL needed to run a form OR click the button labeled "Reset to Default". If you decide to manually enter a value, it would looks something like this:
http://localhost:8889/forms/frmservlet
4. In the field labeled "Web Browser Location:", enter the path and executable to your preferred browser. So for example if IE is your browser of choice the entry would most likely look like this:
C:\Program Files\Internet Explorer\IEXPLORE.EXE
5. Click on OK and retest.
By the way, you can manually enter a URL in the browser. Clicking the RunForm button from the Builder is strictly optional. To run the "test" form directly from the browser enter the following into the browser's address field:
http://localhost:8889/forms/frmservlet?form=test
More information about Forms can be found on OTN:

How to run the job using DBMS_SCHEDULER

How to run the job using DBMS_SCHEDULER
pleas give some sample Iam very new to DBMS_SCHEDULER

Hi
DBMS_SCHEDULER
In Oracle 10g the DBMS_JOB package is replaced by the DBMS_SCHEDULER package. The DBMS_JOB package is now depricated and in Oracle 10g it's only provided for backward compatibility. From Oracle 10g the DBMS_JOB package should not be used any more, because is could not exist in a future version of Oracle.
With DBMS_SCHEDULER Oracle procedures and functions can be executed. Also binary and shell-scripts can be scheduled.
Rights
If you have DBA rights you can do all the scheduling. For administering job scheduling you need the privileges belonging to the SCHEDULER_ADMIN role. To create and run jobs in your own schedule you need the 'CREATE JOB' privilege.
With DBMS_JOB you needed to set an initialization parameter to start a job coordinator background process. With Oracle 10g DBMS_SCHEDULER this is not needed any more.
If you want to user resource plans and/or consumer groups you need to set a system parameter:
ALTER SYSTEM SET RESOURCE_LIMIT = TRUE;
Baisc Parts: Job
A job instructs the scheduler to run a specific program at a specific time on a specific date.
Programs
A program contains the code (or reference to the code ) that needs to be run to accomplish a task. It also contains parameters that should be passed to the program at runtime. And it?s an independent object that can referenced by many jobs
Schedules
A schedule contains a start date, an optional end date, and repeat interval with these elements; an execution schedule can be calculated.
Windows
A window identifies a recurring block of time during which a specific resource plan should be enabled to govern resource allocation for the database.
Job groups
A job group is a logical method of classifying jobs with similar characteristics.
Window groups
A window groups is a logical method of grouping windows. They simplify the management of windows by allowing the members of the group to be manipulated as one object. Unlike job groups, window groups don?t set default characteristics for windows that belong to the group.
Using Job Scheduler
SQL> drop table emp;
SQL> Create table emp (eno int, esal int);
SQL > begin
dbms_scheduler.create_job (
job_name => 'test_abc',
job_type => 'PLSQL_BLOCK',
job_action => 'update emp set esal=esal*10 ;',
start_date => SYSDATE,
repeat_interval => 'FREQ=DAILY; INTERVAL=10',
comments => 'Iam tesing scheduler');
end;
PL/SQL procedure successfully completed.
Verification
To verify that job was created, the DBA | ALL | USER_SCHEDULER_JOBS view can be queried.
SQL> select job_name,enabled,run_count from user_scheduler_jobs;
JOB_NAME ENABL RUN_COUNT
TEST_abc FALSE 0
Note :
As you can see from the results, the job was indeed created, but is not enabled because the ENABLE attribute was not explicitly set in the CREATE_JOB procedure.
Run your job
SQL> begin
2 dbms_scheduler.run_job('TEST_abc',TRUE);
3* end;
SQL> /
PL/SQL procedure successfully completed.
SQL> select job_name,enabled,run_count from user_scheduler_jobs;
JOB_NAME ENABL RUN_COUNT
TEST_ABC FALSE 0
Copying Jobs
SQL> begin
2 dbms_scheduler.copy_job('TEST_ABC','NEW_TEST_ABC');
3 END;

PL/SQL procedure successfully completed. Hope it will help you upto some level..!!

How to make for loop pass only once in a next() method

Good Day!
Can anyone help me or suggest any idea to resolve my problem with the below code, wherein it will only pass the for loop only once. I already tried inserting the for loop in side the if (sqlset4.isFirst()) condition but the problem is it only retrieved the first row of the resultset.
Cheers!
               Statement sOutput = consrc.createStatement();
                        ResultSet sqlset4 = sOutput.executeQuery(xquery);
                        ResultSetMetaData rsMetaData = sqlset4.getMetaData();
                        int numberOfColumns = rsMetaData.getColumnCount();
                        String writefld = "";
                        while (sqlset4.next()) {
                             writefld = "";
                             for (int i = 1; i <= numberOfColumns; i++) {
                                 if (xxformatid.equals("1") || xxformatid.equals("3")) {
                                     writefld = writefld + "sqlset4.getString(" + i + ").trim()" + "|";
                            writefld = writefld.substring(0, writefld.length() - 1) + ")";
                            output.write("\r\n");
                            output.write(writefld);

Hi everyone!
What I actually trying to do is that I have a multiple tables and from these tables I'm going to write each of it into a flatfile that is a pipe delimeted that is why I have to make a loop to know how many fields I am going to write. The code that was attached are actually working, my only concern is that it will take a longer time of processing cause every record of a table it will pass to the for loop(checking how many column) wherein number of column/ were already known on the first loop.
Hi kajbj,
I think what your trying to explain is almost the same with below code which i had already tried. The problem with this is that the every loop of the outer loop data retrieve is only the data of the first record.
               Statement sOutput = consrc.createStatement();
                        ResultSet sqlset4 = sOutput.executeQuery(xquery);
                        ResultSetMetaData rsMetaData = sqlset4.getMetaData();
                        int numberOfColumns = rsMetaData.getColumnCount();
                        String writefld = "";
                        while (sqlset4.next()) {
                             writefld = "";
                             if (sqlset4.isFirst()) {
                                for (int i = 1; i <= numberOfColumns; i++) {
                                    if (xxformatid.equals("1") || xxformatid.equals("3")) {
                                        writefld = writefld + "sqlset4.getString(" + i + ").trim()" + "|";
                            writefld = writefld.substring(0, writefld.length() - 1) ;
                            output.write("\r\n");
                            output.write(writefld);
                        output.close();

How to Run the NEW "System Info Command" in Tiger ?????

I am new to Applescript and was wondering if someone could help me on how to run the new "System Info Command"?
Thanks!!!

The "system info" command that red_menace uses above is the new system info command that's mentioned on the web page you referenced. However, red's example only displays the "long user name" and the "AppleScript version" in the dialog.
The entire system info record actually contains all of these items, each of which you can access just like red_menace shows you in his example:
AppleScript version
AppleScript Studio version
system version
short user name
long user name
user ID
user locale
home directory
boot volume
computer name
host name
IPv4 address
primary Ethernet address
CPU type
CPU speed
physical memory
Steve
PS - if you switch Script Editor over so the bottom pane displays the "Event Log" you'll see the entire system info record displayed in the log when you run red_menace's script.

How to run the Server Side Existing rule in Exchange 2010

Hi All,
There were requirement to create a auto forward rule for almost more than 5000 users, which we did, but the we want to apply this rules to the messages which are already in the inbox for all those users where we have created the rule.
Right now the problem what we are facing is for each individual we have to take full access to their mailbox and execute the rule first time and then it works.
this is becoming challenging for us to making this for all 5000 users. the other problem is those user are not regularly login to this mailbox, they are using some other Org mailbox, so even we can not communicate to all of them.
Q1) How to run the Server Side Command which should forcefully apply whatever rules is created for that user should execute for the messages which are already in the inbox.
Q2) or the powershell for for specific rule name, which can apply on the for all the messages which are there in the inbox.
Any help would be appriciated!
Thanks in adv champions!
Ashku

Hi Ashku,
If these 5000 users are all users in your Exchange organization, a inbox rule can be created by the following commands:
Get-Mailbox | foreach {New-InboxRule -Mailbox $_.Name -Name AutoForward -From [email protected] -ForwardTo UserB}
Based on my test, the Inbox rule created in server side also cannot work on the message that have already been in the Inbox unless users click “Run Rules Now…” in their Outlook client. And the transport rule in Exchange server only works
during the message sending process.
Therefore, there may be no feature in Exchange server side to meet your requirement.
Thanks for your understanding.
Thanks,
Winnie Liang

Scenario : Inventory controlling extraction
Regards
Santhosh kumar N

Hi,
In LBWE --> 03:Inventory -->click on Job Control, and click on Start Date, and give your parameters i,e, date and time and also give Periodic values, i.e. ever day or after some hours like that and then Click on Print param then Click Schedule Job. Then check the status in SM37.
After suceess then check in RSA7. And load data in BW.
Note: For every day delta loads, you need fix Periodic values, because every day you need not to go LBWE and run manually Immediate option. And also loads will happen in night only. So schedule it and also set Processc hain in BW for Loads.

Hi,
How to run the open script code from eclipse.
Please let me any soulutions on this.

Hi Konda
I am not quite sure you can do that and it would even be not supported... Again, what is the purpose? Why do you want to run your openscript code in Eclipse?
What is the code you try to run?
As an example, even if you include al the jar files and so on. don't think the function "Launch Browser" could work because it isn't only java code orjar files.....
If you give us more background. maybe we can guide you to a better solution...

How to run the same SSRS report multiple times, each time with a different parameter value?

Hi,
I have an SSRS report that produces a list of invoices for a single supplier (so supplier is a parameter specified at runtime). The report is based on a stored procedure in SQL. I would like to make things easier and instead of going through all suppliers
one by one, I want to have a single action, which produces separate reports, per supplier, for all suppliers that have an outstanding invoice (so not all suppliers on the system as a whole but all suppliers that are within the result set of the stored procedure).
I assume this would mean first executing the stored procedure to find all suppliers that have invoices at the time. And then running the report multiple times, once for each supplier, where the supplier value is used as the parameter every time. ideally
this would open separate webpages with a single report per page. (I am creating a button in another software, which is simply launching iexplore.exe and passing a
fixed SSRS report URL).
What would be required? I have SQL 2012 and I am building this in Report Builder 3.0.
Thank you!
Dimitar
P.S. What about still running ONE report, but every supplier starting on a new page? Is that more realistic? So supplier will not be a parameter any more, but just something that creates a new page on the report?

What
about still running ONE report, but every supplier starting on a new page? Is that more realistic? So supplier will not be a parameter any more, but just something that creates a new page on the report?
Yes thats a much better option. Its very easy to generate such a report in SSRS. You dont need a parameter
in that case but just needs to add Supplier as a grouping field in the tablix. Then add other columns and groups if required. Select option set page break after each instance of the group for first grouping (ie based on supplier field). Then report will render
with one page per supplier. On exporting to excel also each supplier data goes to a different tab
Here's a similar requirement I did for one of my projects
