• How to check if a table exists in the database or not?

  People,

  Hello. I use the server of Oracle 11 GR 1 material with Oracle Linux 5 database.

  My instance of database is named HRCS90, which the user access Id is MyName, and his identification of user SYS system.

  I have a few questions about user ID to access the PSRECDEL and PSROLEDEFN table in the HRCS90 database as below:

  SQL > select * from PSRECDEL;

  His output under the SYS user: table or view does not exist.

  His output under user myName: no selected lines. This means that the table THAT PSRECDEL exists, and myName user can access.

  SQL > select * from PSROLEDEFN;

  His output under SYS and MyName: table or view does not exist.

  My questions are:

  How to check if a table really exists in the instance of database HRCS90 or not?

  Thanks in advance.

  
  

  If a table is present in the database, it must be present in DBA_OBJECTS. If he fell, he would be present in the TRASH. If he fell purged, it is not available in the database, Cant it confirm you this object is not in the database? See a little test here

  SQL > CREATE TABLE TESTTAB (ID);

  Table created.

  SQL >

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB.

  OBJECT_NAME OWNER

  ------------------------------ ---------------------------------------------

  SCOTT TESTTAB

  SQL >

  -Drop table (without purging. So now, it will be in the recyclebin)

  SQL > DROP TABLE TESTTAB;

  Deleted table.

  SQL >

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  OBJECT_NAME ORIGINAL_NAME OWNER

  ------------------------------ ------------------------------ --------------

  SCOTT BIN$ 8LKloIv3SYWA0WJ33GS + Aw == $0 TESTTAB

  Now see this case when you use PURGE. If it won't move the table to the trash. First of all I am clear the existing dba_recyclebin to the user entries. Then I'm falling table using purge.

  SQL > PURGE TABLESPACE USERS USER SCOTT.

  Purged tablespace.

  SQL >

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  no selected line

  SQL > CREATE TABLE TESTTAB (ID);

  Table created.

  SQL >

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB;

  OBJECT_NAME OWNER

  ------   ----------

  SYS TESTTAB

  SQL > DROP TABLE TESTTAB PURGE;

  Deleted table.

  SQL > SELECT * FROM DBA_RECYCLEBIN WHERE ORIGINAL_NAME = "TESTTAB;

  no selected line

  SQL > SELECT MASTER, OBJECT_NAME FROM DBA_OBJECTS WHERE OBJECT_NAME = 'TESTTAB;

  no selected line

  Since there is no entry to both DBA_OBJECTS and DBA_RECYCLEBIN. So that means that the particular object is not in the database.

  EXISTS checks for the existence of an element, not a value. Since you're using VARRAY (btw, it is not recommended), your only choice is a loop through:

  SQL> DECLARE
    2       TYPE dnames_var IS VARRAY(7) OF VARCHAR2(30);
    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');
    4  BEGIN
    5      for i in 1..dept_names.count loop
    6        if dept_names(i) = 'Shipping'
    7          then
    8            dbms_output.put_line('Exists ................');
    9            exit;
   10        end if;
   11      end loop;
   12  END;
   13  /
  Exists ................
  
  PL/SQL procedure successfully completed.

  If you use the nested table, you can use MEMBER, SUMBULTISET, MULTISET EXCEPT:

  SQL> DECLARE
    2       TYPE dnames_var IS TABLE OF VARCHAR2(30);
    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');
    4  BEGIN
    5      if 'Shipping' member of dept_names
    6      then
    7         dbms_output.put_line('Exists ................');

• My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009:

  My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009: cannot access a property or method of a null object reference.

  I have a very simple question. I want to take the value of

  Event.Result.Item.nodeindex1.nodeindex2.Row.MyValue;

  and assign it to a text field

  mytextTi.text = event.result.item.nodeindex1.nodeindex2.row.myvalue;

  But if a part of the tree is missing, which is also valid, so I get TypeError: Error #1009: cannot access a property or method of a null object reference.

  I tried various solutions such as the following. Is there any simple way to do this?

  If (event.result.item.nodeindex1.nodeindex2.row.myvalue! = undefined)-does not work

  Unfortunately, one must test all levels to ensure that it is not null before the reference to it. You can take advantage of the short-circuit evaluation in tying together, for example

  if (event.result.item
      && event.result.item.nodeindex1
      && event.result.item.nodeindex1.nodeindex2
      && event.result.item.nodeindex1.nodeindex2.row
      && event.result.item.nodeindex1.nodeindex2.row.myvalue)
  {
      // access the variable
  }
  else
  {
      // one of the XML nodes in the path is null
  }
  

  Or you could stay away from her a little hacky and wrap the reference in a try/catch block.

• How to use resource element in the xml file in the workflow?

  Good afternoon

  In my workflow, I put a parameter of the attribute with the element of resource type and the value of the attribute is an xml file.

  And I had a problem with xml files in my workflow, I would like to use the information in the xml file to store in the variable...

  Example: in the xml file, I put some information about the number of VLAN ID, and in my script task, I would like to know how is used with myvariable.portgroup [0].spec.vlanId?

  Best regards.

  Like this:

  var myXml = new XML(resource.getContentAsMimeAttachment().content);
  

  You can then access your nodes like this:

  myXml.node.subnode

  Google for e4X to get the syntax complete.

• How to import the xml file into bcc?

  My input to atg file is xml containing assets of category or products.

  I want the Scheduler to run to auto create a project and send an e-mail to the customer for approval.

  When the client approves the xml file, and then run the Scheduler to get the data from the xml file into bcc.

  I use: SingletonSchedulableService for this

  Give me a direction for the same thing.

  Thanks in advance.

  I want to implement this in bcc.

  What listener will listen to the authorization of the client for email (that contains the XML to import) we sent to him?

  You will need to do a custom development to hang your workflow customized with incoming e-mail. To send notifications by mail electronic action is already there, and while creating his element within the ACC, you can specify a JSP page for the email template. You can view the rest of the relevant documents:

  Oracle, Web ATG Commerce - Workflows

  Oracle, ATG trade Web - action workflow items

  I recommend you to consult the existing source of DeploymentEmailer in \Publishing\samples\Java and see different types of DeploymentEvent and States can be used, based on your requirement in your custom component. See also these API javadocs for the process and the events of deployment available:

  DeploymentEvent (ATG Java API)

  DeploymentServer (ATG Java API)

  ATG has a component/atg/dynamo/service/POP3Service to retrieve messages from a POP3 e-mail server, but it is mainly used to detect the bounced email. Not too sure if it helps or adjustment in your case, but still you can go through all the details to know what is already there:

  Bounced from Oracle ATG Web Commerce - E-mail

  You can also check the event InboundEmail and API javadocs for InboundEmailMessage which are used in this function of rebound detection E-mail:

  Oracle, ATG trade Web - InboundEmail event

  InboundEmailMessage (ATG Java API)

  Now based on all this, if you extend and customize a lot of things, that it would be little complex and tedious detect mail incoming approval based on its content and then advance your workflow. Another approach may be to put a URL in the e-mail template of your notification by e-mail that the approver will click and on the landing page, you can authenticate and advance your workflow to the needs.

• Clone several nodes and appl_top shared using the XML file backup

  Can I use work save file of application context to repeat the clones and avoid to perform following steps:
  
  -Configure the node C (run '"perl adclonectx.pl sharedappltop contextfile = < context of Applications for the existing node file >' and ' perl-I < AU_TOP > / perl txkSOHM.pl"orders ")
  
  If I work the previous clone XML, I would be able to use the same XMl file for re - clone without implement shared appltop and add a node step. Please, share your ideas.

  You should be able to use it. However, according to the Oracle docs support is to clone the main node and add more nodes by cloning the context files.

• How can I autorun script that will process an XML file at the opening?

  I use image 11. I have a saved script that looks for the event Constants.FA_Note_PostOpenXML notification. When this event is raised, the script is supposed to examine the root element (so I change only the appropriate XML files), then make some changes to the file. Specifically, I want to be able to delete empty pages, remove the room for the heads side and correct table formatting (for example the left indent, whereby I can not directly access, apparently, in the rules of the EDD or R/W). The code snippet that starts to do the following work:

  
  

  Notification (constants.FA_Note_PostOpenXML, true);

  function {Notify (note, object, sparam, etriqu)

  switch (note) {}

  case Constants.FA_Note_PostOpenXML:

  doTheWork();

  break;

  }

  }

  function doTheWork() {}

  var doc, flow, root, elemName, mPageAttrib, topicElem, topicElemName, allAttribs;

  doc = app. ActiveDoc;

  flow = doc. MainFlowInDoc;

  root = flow. HighestLevelElement; will always get something although unstructured document

  While (root. ObjectValid()) {//only do something for structured documents

  elemName = getElementName (root);

  .. more code to do things...

  }

  }

  I check then the element name root, and if it matches, I make a few changes. This code works fine when operating manually. But, when it is run as a recorded script, the app. ActiveDoc object is invalid, and there is no structure to edit. (I added the line if(!doc.) debug ObjectValid()) {alert ("invalid");} that is not included above.) It seems that the Constants.FA_Note_PostOpenXML event fires whenever the XML file opens, but BEFORE frame bed actually.

  Does anyone have recommendations on how to get around this? Is there something else I could use instead of Constants.FA_Note_PostOpenXML? Is there another way to manipulate an XML file automatically when loading?

  Thanks in advance
  

  The notification event receives four settings: note, object, sparam and etriqu. For the event that you are using, the object must be the subject of document of the FrameMaker document being opened. Then, you should be able to use this:

  doTheWork(object);
  

  Make sure that you update your doTheWork function to receive the Doc object:

  function doTheWork(doc) {
      var flow, root, elemName, mPageAttrib, topicElem, topicElemName, allAttribs;
      flow = doc.MainFlowInDoc;
      root = flow.HighestLevelElement; // will always get something even if unstructured document
      while(root.ObjectValid()) { //only do something for structured docs
          elemName = getElementName(root);
          ...more code to do stuff....
      }
  }

  You must

  1. Read in the XML file
  2. Analyze the document in an XML (just one big struct) object
  3. Insert your XML code of the object where you need
  4. rewrite the XML file with your data now included
