How to purge the members of a collection of old sessions...?

Hello

How can I clear out all members of the collection with old sessions on a regular basis...? Now it seems to be purged every 12 hours, I want to purge them every 2 hours...

Is there a way to know if a former session is valid more...?

Thanks, Jürgen

It should be check-high water of the collection table. Like any other table, the FTS query performance can suffer if you did climb the route HWM by inserting a large amount of data, then by removing most. Retrieve the contents of the collection could involve some TSPS. In my case, truncate table collection to shrink the HWM back to a size approproiate srestored over my performance. Since you have a large number of separate sessions, FTS can be less likely.

I use collections in the reports of the results of "cache" of complex queries slow on db links. Paging through result against the collection sets can be much more reactive that repeat the same full query via a db connection. Inserting query result sets very important collections can push up the WHM.

  • How to purge the old deleted mail. My iphone shows that I have 17 000 messages to download!

    I use windows mail, and for many years, even since he was called Outlook Express. I still have the old messages deleted and permanently deleted. But, now that I have an i phone I'm having a problem. Even if I did that my phone configured to receive 25 messages at the same time, it indicates that there are 17 000 waitning to download. How to purge all old messages?

    The items removed from your computer folder is under your control.  You can remove yourself if you want, but they are now independent of the server.  That's if you are referring to a POP3 account.  Unfortunately, I'm not experienced with IMAP accounts and so if this refers to such, I can't help more.  But if its POP3, what will happen is you will continue to download the messages to the phone and the computer, and then when the computer sees all messages on the server are more than 5 days, then it will tell the server to remove these messages from the server.  But the messages will remain on your computer and phone, unless you delete them.

  • How to purge the tables using odi?

    Hello

    I want to purge the data in the target. That data my political is to remember that the only 90 days. I have to keep the only 90 days of data. How can I do this in ODI. I don't have a single column DATE.

    Thank you

    Kind regards
    AMSII

    If your existing date field can be used to identify records to be served, then you can simply create a procedure in ODI along the lines of

    delete of < %="odiRef.getSchemaName" ()="" %=""> . * your_table * where your_date_field< (sysdate="" -="">

    It of the easiest way, but beware of your index finger on the table, that they don't get too fragmented. You might also consider using a strategy of daily score on the table that would allow you to remove partitions over 90 days, which would be much faster.

  • How to purge the Workflow queue after upgraded to R12 before the Mailer WF?

    Hello

    We are about to upgrade to R12.1.3 of R11.5.9.

    As part of the test, I configured and started the workflow Mailer in the new system. As soon as I did, the system began to send only a ton of notifications of recent approvals of requisition apparently waiting in line in the system. WF Mailer has been down since I did the last upgrade test.

    We intend to approve applications from before the changeover in the old system, so there should be no e-mail notifications in the waiting. Is there a way to msg_state of these notifications was updated in the table wf_notification_out with a value of "READY", so we can ensure that we will have a clean system, and users will not receive notifications about recent requisition approvals?

  • How to get the Type of a Collection class

    Hi all
    I just want to ask if there is a simple way to get the type of a Collection class.

    For example, for an ArrayList < String > or items of list < number > integer, dynamically how 'String' or 'Integer' class object (expecially with generic types) without any sequences of strange reflections?

    Java generics follow one main erasure called which essentially States that any generic info is maintained during execution. If you can not, even if you can get information about variables and fields of reflection.

  • How to sort the members of the dimensions in planning by ODI

    Hi all

    I need a suggestion for this problem

    I m building dimension in planning using the ODI Conector and I need to sort members in the dimension, I set the property 'LOAD_ORDER_BY_INPUT' in the tab 'flow', but does not work, anyone have an idea to solve this problem

    I use EMP 11.1.2

    Thanks in advance
    Cristian

    LOAD_ORDER_BY_INPUT takes as input, you are sure that the members are in the correct order when it passed through the transit area.
    In any case I usually customize the IKM to use an "ORDER BY" on the SQL statement.

    If you have a look at this post:-http://john-goodwin.blogspot.com/2010/07/planning-1112-additional-odi.html
    And search for the position of "* what we need to do is to order the files loading."
    He will explain how to go about the personalization of the IKM

    See you soon

In the front, there is the option select all and delete however it is only for entries on the current page.

    If it is not one option, the only other alternative, I can think of is to remove the entries through SQL, but I'm not sure of the model of data and what are the constraints might possible be violated.
