Set dblink via parameter

I have many scripts which read data from source databases via various dblinks. I use DBMS_Jobs to run these automatically every night. There is now a requirement be able to set the dblinks using a parameter. How can i do this?
A secondary problem will be that the jobs are run automatically without intervention, so presumably I will need to set the parameter in a separate file, so that all the scripts will read this file when they are run.

You can use dynamic sql for dblink as a parameter.
Example:
PROCEDURE delete_dept (db_link VARCHAR2, dept_id INTEGER) IS
BEGIN
EXECUTE IMMEDIATE 'DELETE FROM dept@' || db_link ||
' WHERE deptno = :num' USING dept_id;
END;
You can use UTL_FILE package to read a file.
Put all the parameters of each procedure in a file line by line.
Read the parameters and pass these to your other procedures.
For UTL_FILE issue, this is just an idea. I did not test it.

Set and get parameter id

Hi,
I need to store one variable value and I need to retrieve the same variable value in same program. For this I have written set and get parameter ids in the same program. It is working fine but if I log off the system and if I logon the system it is not working I mean before log off the variable is showing some value if I log on again that variable is showing empty. But I want to capture the field values after log off and log on also. Is there any other option can I use table?
Please help me I will give points.
Thanks.

Hi
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table <b>TPARA</b>.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.
export itab to memory id 'TEST'.
import itab from memory Id 'TEST'.
Here itab should be declared of same type and length.

How to set the tables parameter to a BAPI using adaptive RFC model

Hi,
I have a BAPI ZBAPI that has a tables parameter ZPernr of type ZTable with two elements pernr and name.
I used adaptive RFC model and created model classes for the BAPI.
My question how do i set list of pernr and name to the tables parameter in the webdynpro for java.
I have the following methods available
ZBAPI input = new ZBAPI();
1.ZTable table = new ZTable();
table.setPernr(pernr);
table.setname(name);
input.addZPernr(table);
how do i set the table parameter for multiple pernr and name
2.
add all the pernr and name to list and set that list to input in the following way
input.setZPernr(list) and list of typecom.sap.aii.proxy.framework.core. AbstractList
out of two methods mentioned which one is correct.
Please let me know the solution
Thanks
Bala Duvvuri

Hi Bala,
            In your code:
List pernrList = new ArrayList();
pernrList should be declared as the type of class HROBJECT   ( The structure name in the model e.g. the node PERFWARN type is Zhrecmfm_002_Perfrat_Warning_Input )
Try this:
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr);
input.setPernr_List(pernrList);
// call BAPI execute method
If you want to pass list of pernrs, you can pass in alternate way
IPrivate<viewname>.I<nodeame>Node prNode = wdContext.node<node>();
IPrivate<viewname>.I<nodeame>Element prEle;
for (int i = 0; i < table.size(); i++) {
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr); // Set the pernr from current record
prEle = prNode.create<nodeame>Element(pernrList);
prNode.addElement(prEle);
// call BAPI execute method
Once I execute the BAPI how do i iterate thru second table parameter PERNR_PERFRAT to get pernr and performance rating text
Say your node name is PERNR_PERFRAT
for (int i = 0; i < wdContext.nodePERNR_PERFRAT().size(); i++) {
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPernr();
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPerfrat();

IPod touch failed set-up via USB - please help?

NB - this is not related to my Mac computer. I am connecting an iPod touch 4th generation to a Windows machine running XP (SP3).
The iPod is new and I can't get it to set up via USB connection to computer running iTunes (I have mobile broadband, and it isn't a wireless connection). I have tried the minimum, older version of iTunes and the most up-to-date version.
On connection, both the iPod and iTunes acknowledge each other and the iPod charges. It says "connected to iTunes", but does nothing further. Once the screen saver blanks the screen, it simply shows "connect to iTunes" again, clearly part of the set-up process, when I re-activate the screen.
In iTunes, the iPod Touch comes up under "Devices" at the left-hand side of the iTunes display, but I can't click on it to reveal anything about the iPod - nothing happens. At the same time, a progress bar appears at the tope of hte window saying, "accessing iTunes store" (I'm assuming this must be part of the set-up process?!), but it never completes. Sometimes, I get an error message telling me I have no active internet connection (the connection IS active, but I have also emailed my service provider in case this is relevent), but mostly it just hangs - in short, I can't do anything.
I can't tell you which version of the iOS the iPod is running, because - you've guessed it - it will only run its set-up procedure, and that's not completing, so I can't find out anything about it...
So disappointed, and very dispirited after spending days on this and getting nowhere. Apple has not responded to a service request thus far.
Desperate to get this sorted out, because the whole point of finally getting an iPod (which everyone told me would be so simple to set up and use) is because I'm doing a really big charity walk in a couple of weeks - that, and the training walks, are really long (next one, tomorrow, is seven hours), and doing them without music is soul-destroying.
If you can help, I'd be grateful beyond words.
Thanks for reading,
Sheri.

Why do Apple not respond to correctly initiated support requests?
This is taking weeks to fix on my own - that is *crazy* in this day and age. Here is an update. Sorry it's long, but it's in case it helps anyone else. I tried *everything*.
What did it in the end was a tiny - REALLY tiny - thing, but I suspect it wouldn't have worked if not in combination with several other things.
It's a setting in internet explorer, which I use rarely if ever, but a friend (i.e. a stroke of luck that he was around) pointed out that iTunes uses it in the background to work properly, and it's a security setting in the "Advanced" tab of the "Internet options" bit of IE. You need to UNtick the box for "Check server's certificate revocation". Which suggests that, before doing this, iTunes was going into an endless loop of checking. Not sure about that, but anyway - it worked in terms of getting the oPod recognised and set up (but see later in the post for the current situation). BUT... before that, I'd had to:-
1. via my firewall, open two ports (80 and 443) needed by iTunes (I think this was key as well, actually - why on earth doesn't this sort of support come with the kit?)
2. uninstall latest iTunes and revert to a previous version (may or may not have been necessary, but seemed logical especially as the iPod's iOS wouldn't be up-to-date) - that needed doing twice, as the first version I tried was *too* early for a 4th generation touch
3. flush the resolver cache several times, and various other command-line actions
4. try all connecting and communicating in different orders (e.g. trying to authenticate iTunes *first*, before connecting iPod) - but now I've seen the set-up process once through in its entirety, it's become *so* obvious that none of that was working, so it's partly my inexperience with iPods which made it take so long to find the solution
5. try to set it up via the iTunes website instead (fail!)
6. test secure site (https) access and inputting various server addresses to see if my firewall or mobile broadband provider was blocking them
7. attempt connection with various parts of virus protection and firewall disabled, and even disable the entire firewall
Not to mention endless emails and discussion forum contributions, reading and tweaking, all the re-boots...
CURRENT SITUATION
Lots of aspects working, but as soon as I ask the iPod to do anything internet related (use Safari, access App Store, etc - or even just sign in), it returns the message, "Cannot connect to iTunes store" - despite being connected by a cable to a computer which IS connected to the internet and IS running iTunes, IS accessing the store, HAS synced with and updated the iPod...
Absolutely NOTHING in Apple "support" discussions/documents makes any difference, and is almost exclusively aimed at those connecting wirelessly anyway (so lots of stuff about routers, DNS settings, etc.); wireless is not an option oopen to me.
Unbelievable.
Any suggestions which don't just point me to an Apple support document would be very welcome, because I think I have read them all...

How to set this DATS parameter

Hi Pros,
I am calling function 'HR_FORMS_TIM_GET_B2_RESULTS' in the program , its input parameter is BEGDA, I transfer a date variable to BEGDA, but does not work. can not get any data. but if I run this function in SE37, I input date '20140807', successfully get result. please tell me how to set this DATS parameter?

Hi,
You might be passing the date in '12.12.2014' or '12/12/2014' format. Please
use the function module 'CONVERSION_EXIT_BEGDA_INPUT' to convert the date
to internal format and then pass it to the function module.

It's clearly not impossible, just different than you expect. Create your playlist as you want it to appear in the Current tab (meaning don't dump every single song from your library in there, just the ones you want) and then save the playlist.

Look at save_absolute_paths_in_playlists in your mpd.conf.

Setting Up a Parameter

I have set up a parameter, but I know I missed the last step. It works to the point it asks for the information when you open the report, but then it doesn't filter the report. I have a feeling I missed the boat on the filter. Any help would be appreciated.

Go to the Select Expert. Select a field, "is equal to", and the parameter. This will cause the report to display the parameter and then use it to filter the data when the report is run.

Setting personalization via profile parameter in the business role vs su01 personalization

We are trying to have the personalization for a user on login determined by the business role they choose (if they have more than one) via the profile parameter in the business role.
Setting the personalization this way doesn't seem to get picked up for the user, any experience with this issue?
Regards,
Curtis Finchercr

Hi Curtis,
In CRM, users can personalize their screens by logging in to web client by selecting the business roles.
Once they are in to the business role they can able to see "Personalize" option on right hand side top corner. If they click that option they can able to modify their own data (personal information), Lay out, Settings, Groupware integration and Favorites modifications as well.
Thanks,

Hot to Dynamically set Group Filter via parameter

To display top X records per group in a report, we can set the group's filter type = First and Number of Records = X. What if X is variable and is passed as a parameter?

To dinamically set a group filter use a bind parameter, e.g. :MAX_Records. A second (dummy) bind parameter which has to be reset at a level above this group e.g. :INC_CNTR has to be defined. Then edit the function for the group where your filter should apply to.
BEGIN
:inc_cntr := :inc_cntr + 1;
if :inc_cntr <= :max_records then
return (TRUE);
else
return (FALSE);
end if;
END;
:MAX_Records can then be set at runtime through the parameter form.
Hope this is what you were looking for.

Accessing tables through DBlinks via ADF BC entities, jdev11.1.1.2.0

To my understanding, everytime any object is accessed via a dblink, a transaction is created on the database; even if one merely selects from a table. For example, whenever we were writing PL/SQL, after we were finished accessing data through a dblink we performed a commit to close any open transaction that opened via selects. Using ADF BC, if we create an entity that accesses a table via dblink, what guarantee that transaction sessions are closed after simple selects (no DML)? How would these transactions be closed if data from a db link is simply displayed in an ADF table or referenced via LOV? Is there perhaps some setting that can be set to open connections without transactions?
Reference: http://www.jlcomp.demon.co.uk/faq/dblink_commit.html
Best Regards,
Valon

valon,
This is indeed a tricky one. You are correct that a transaction is started whenever you do any selects that touch a remote object. The problem that I see is that even if you were somehow able to execute a commit after every SELECT statement, the transaction always executes in the context of an application module - if you committed the transaction, you'd also commit any outstanding transaction going on in the AM at the time. In general, this would be a bad thing, although you may be able to ensure that it is OK for your specific use case. I did a quick scan of the APIs to see if I could locate any method that you could possibly override, but didn't locate anything that looked promising.

Facelets - setting locale via link

Hello Everyone,
I am developing a small web app. A file upload with additional params, its processing on submit and returning the final chart (an image). There are two links for switching to another locale and one for a help page.
The first version was made as JSP page with EL tags and backing servlet. It worked fine but I found the final image can't be saved on local disk. Later I figured out it is caused by browser behaviour during 'save' action, when the servlet is called again (if the image is not already in cache), but as original parameters are missing in this phase, creating of the final image fails.
Trying to solve my problem I've found PRG pattern [1] which seems to be promising answer. I've chosen facelets framework (Mojarra) and tried to refactor app logic a bit. As I see, the complexity of the whole solution grows... and not everything I am able to solve...
My current blocker is a language switcher. What could be in JSP made relatively easy using the following code at the beginning:
<c:if test="${param['locale'] != null}">
<fmt:setLocale value="${param['locale']}" scope="session" />
</c:if>and handled by very simple links:
<a href="index.jsp?locale=en-GB">English</a> | <a href="index.jsp?locale=cs-CZ">Czech</a>is now unsolvable issue for me.
After long trial error path I set up the following way, but it still doesn't work properly.
In xhtml:
<f:view encoding="utf-8" locale="#{localeBean.locale}">
<h:form>
<h:commandLink action="#{localeBean.setLocaleEx}">
    <f:setPropertyActionListener
       target="#{localeBean.locale}" value="en"/>
    English
</h:commandLink>
<h:commandLink action="#{localeBean.setLocaleEx}">
    <f:setPropertyActionListener
       target="#{localeBean.locale}" value="cs"/>
    Czech
</h:commandLink>
<h:outputText value="#{localeBean.locale}" />
...In Bean:
@ManagedBean
@RequestScoped
public class localeBean {
    protected String locale = "cs";
    public String getLocale() {
        return locale;
    public void setLocale(String locale) {
        this.locale = locale;
    public void setLocaleEx() {
}Click on generated link really change localeBean.locale value which is displayed using directive h:outputText, but...
1. refreshing of the page is very very slow on my quite recent PC (I use Tomcat 6 as the container - the JSP delay was undetectable)
2. no locale is changed (a f:view locale atribute is probably ignored)
3. in the final HTML page there is a quite long JavaScript
... so unacceptable for me.
Can I create links which can change locale more straigforward and reliable way? And without that JavaScript?
Can I set f:view locale using any parameter sent using a simple URL link like Czech ? I need this setting also for Help page, so a session scope is required. Can this be done via facelets?
Curently I am puzzled a bit...
Thanks in advance for any hint.
Regards,
Jan
[1] [http://blogs.sun.com/enterprisetechtips/entry/post_redirect_get_and_jsf|http://blogs.sun.com/enterprisetechtips/entry/post_redirect_get_and_jsf]

ad 1) refreshing of the page is much better now (maybe there was a memory problem)
ad 2) locale seems to be updated, but I still don't know why my strings are not localized according to this locale
ad 3) if JavaScript is disabled in a browser, switching of locale doesn't work anymore. It would be better to avoid JS at all, but I resigned.
I've found my initial approach is wrong. When some form values are edited and locale is changed in a proposed way, these parameters are reset to their default values.
What I probably need is applying PRG pattern also on this part - somehow to set a new locale and then refresh the same page. I've tried that using 'metada' element at the begining of the page, but it is not very clear how to change locale via commandlink:
<f:metadata>
   <f:viewParam name="loc" value="#{localeBean.locale}" />
</f:metadata>
<f:view encoding="utf-8" locale="#{localeBean.locale}">
<f:loadBundle basename="messages" var="i18n" />
<h:commandLink action="index?faces-redirect=true&includeViewParams=true">
   <f:setPropertyActionListener target="#{localeBean.locale}" value="cs"/>
   Czech
</h:commandLink>as I am getting message when this link is clicked: Conversion Error setting value 'en' for 'null Converter'.
('en' is the default locale set directly in the backing bean)
There is probably impossible to use 'setPropertyActionListener' in this kind of command link, but I have no better idea.
Tu sumarize that, I need a form with two links for switching texts to another locale and one submit button for sending form data to my servlet, all that using PRG pattern to avoid resubmitting once sent data. I prefer the simplest solution.
From my point of view this is the basic feature of any web and I am quite upset that it is still unclear how to resolve it.

Where to set Java system parameter for embedded WLS in JDev 11g?

Hi,
I am trying to test web service invocation via JAX-WS proxy generation on Jdeveloper 11g.
When I test client code, I got following error message.
Exception in thread "main" java.lang.Error: Jaxrpc 1.1 method is not supported.
at weblogic.webservice.core.rpc.ServiceFactoryImpl.loadService(ServiceFactoryImpl.java:65)
From a forum discussion, it was suggested to add following java parameter in the path.
-Ddebug=true -Djavax.xml.rpc.ServiceFactory=oracle.j2ee.ws.client.ServiceFactoryImpl -Djavax.xml.soap.SOAPConnectionFactory=oracle.j2ee.ws.saaj.client.p2p.HttpSOAPConnectionFactory -Djavax.xml.soap.SOAPFactory=oracle.j2ee.ws.saaj.soap.SOAPFactoryImpl-Dweblogic.log.Log4jLoggingEnabled=true -Djbo.debugoutput=console
I can not find where to set this parameter under "Tools"->"Preferences". Is there any place in IDE that I can set this value?
Thanks for the help,
Jim

The parameters are defined in the Run configuration of your application. You find the Run configuration in the project properties under run. Open the 'Default' configuration, there you find the java properties where you put the parameters.
