Echo letter /proc/sysrq-trigger not-working? [Solved]

According to various resources including https://fedoraproject.org/wiki/QA/Sysrq … it_work.3F
It's possible to write a letter to trigger a sysrq command like so:
[root@a-pc proc]# echo t> /proc/sysrq-trigger
'm' - Will dump current memory info to your console.
Edit: apparently the info is outdated? At any-rate it writes correctly to journal rather than to console (I did check the journal as well before posting but I had a few processes on watch and forgot to filter those :S). Feel free to delete this post if it's not contributing anything.

Thanks for the tip, but I just discovered the issue on my own: I actually forgot to install "xf86-input-synaptics". (Well, it's the newbie corner... )
I think I installed it the first time I tried to get everything to work, and then forgot about it the second time I installed Arch on my machine... Sorry for all the fuss about nothing, apparently.

Format Trigger not working in 10g Report.

I have a report with two eclipses
(*) Debit (*) Credit . Please note that the two asterics denotes eclipses.
I have a format triggers on these eclipses based on the database item Debit_credit.
IF :debit_credit = 'CREDIT' THEN
RETURN FALSE;
ELSE
RETURN TRUE;
End if;
and vis-visa. However the format trigger is not working. Regardless of the value of
debit_credit. I even created a frame around these eclipses and put my format trigger all to no avail. Please help.

Create a boilerplate text in your repeating frame (get rid of the field :debit_credit from your layout, but leave it in your query). I created the boilerplate field B_1. My format trigger looks like:
function B_1FormatTrigger return boolean is
begin
if upper(:debit_credit) = 'CREDIT' then
srw.set_field(0, to_char('(*) CREDIT'));
else srw.set_field(0, to_char('(*) DEBIT'));
end if;
return (TRUE);
end;I hope I understood your question OK...I am not sure what an eclipses is?

IPod Buttons not working - Solved

I have a 60G iPod that wasn't working and I resolved it. I don't know what generation iPod I have but I bought it in 2005. Anyways I was recently having issues where the buttons just weren't responding no matter what I did, it was just unusable. I couldn't play music adjust the volume or even reset it. I solved my problem by plugging it in to charge, toggled the lock button and then the buttons worked. I reset it (menu center for about 10 secs.) I was on this forum looking for an answer and couldn't find one. I just hope this helps someone else.

Gnome-online-accounts in gnome 3.2 not working[SOLVED]

gnome-online-accounts in gnome 3.2 is not working.it gives a bad token request.are other arch users experiencing this problem.
Last edited by PranavG (2011-10-02 15:52:33)

There are issues with the proxy settings, and I had weird situations depending the network I was connecting...
When I use my wireless network I can use the online accounts correctly.
When I use a foreign wireless, mostly sure I can't.
And when I set a local proxy (e.g. pivoroxy) for https protocol, I get this error while adding the account:
http://www.mail-archive.com/desktop-pac … 25738.html
That could be solved just by issuing:
$ export https_proxy=
$ gnome-control-center
Hope this could be useful for you,
Regards,
EDIT: for some reason I wrote "I get this error will adding the account" instead of "I get this error *while* adding the account".

Business Rule in trigger not working

Hi,
I have business rule that no one below 18 years should be employed in this system.
I have created a trigger that alerts me so, but when ever I insert someone either over 10 or below, it fires and deos not insert any record, but if I deleted the trigger, everything works fine.
I should have put a check constraint (s_hire_date - s_dob) < 6570 on the table, but I just thought should be able to do it.
Why please?
stops insertion of under 18 years into employee table
CREATE OR REPLACE TRIGGER Tr_new_employee
BEFORE INSERT ON employee for each row
DECLARE s_hire_date DATE;
s_dob date;
begin
select :NEW.hire_date, :NEW.dob into s_hire_date, s_dob from employee
where empid =:new.empid;
IF (s_hire_date - s_dob) < 6570 then
raise_application_error(-20101,'Person too young');
end if;
end;
Many thanks in advance

I know your logic is fine, something might be wrong with the trigger even though it created succesfully. It is not doing what it is intended to do.

Oracle Form Services Installation (Test.fmx) Trigger Not working

Hi
I install oracle BI and forms Services on oracle application infrastructure after installation i run the following command "http://ora.server.com:7778/forms/frmservlet?config=testfrm" it will show the form "form services install sucessfully" but when i do a certain cusmization on it i.e. put a one text box on that text put put a key_next tigger in which i show a alert message only. After Customization i run a same URL it will again show that form with the changes but the trigger (Key_next) will not fire
I don't understatnd why tigger is not working or fire.

So we understand things correctly,
You are running a form and a trigger won't fire. What kind of trigger? A when-button-pressed, or a key-next-item, or something else? I don't believe key_next is a valid trigger.
If you are using a key trigger, you need to make sure that the keys are mapped as you expect. You can see how the keys are mapped in the menu under Help => Keys when you run the form. Make sure the button is mapped like you expect. Additionally, you can modify the mapping by updating the resource file, but that's kind of outside the scope of this...
This type of questions really is suited for the Forms forum under Developer Tools => Forms at: Forms
If you need more help, post there. The focus of that section if Forms.

Logon trigger not working over DB-Link?

Hi all,
I have a serious question about accessing tables over a database link.
I have three schema:
DATA@SOURCE
INTERFACE@SOURCE
WORK@TARGET
Schema DATA has one table called T1
The INTERFACE schema has select privileges on all tables from DATA. Furthermore schema INTERFACE has a logon trigger to change the "current schema" to DATA:
CREATE OR REPLACE TRIGGER TRG_A_LOGIN_SET_SCHEMA AFTER LOGON
ON INTERFACE.SCHEMA
BEGIN
execute immediate 'ALTER SESSION SET CURRENT_SCHEMA = DATA';
END;
The WORK schema has a database link to the INTERFACE schema called INT_DB_LINK.
I am now logged into schema WORK on the TARGET database and I am executing following statement:
select a from T1@INT_DB_LINK
-> it's working
Next I execute
declare
cursor c is
select a
    from T1@INT_DB_LINK
   where rownum<2;
begin
for r in c loop
    null;
end loop;
end;
This is not working. Error message is ORA-000942: table or view does not exist.
But why?
Can anyone help me?
Thanks in advance
Py

Hi all,
after a long, very long search I found what caused this strange behaviour.
The ORA- Error was not raised by the SQL-Execution-Engine but by the SQL-Parser/SQL-Validation.
As the second statement is an anonymous SQL block the Oracle Parser checks all objects dependencies before execution.
This means a connection is established from TARGET to SOURCE checking if table T1 is available. The strange thing is
that on this connection the "ALTER SESSION" trigger is not fired. So the parser does not find object T1 in schema INTERFACE.
If I create an empty table T1 in INTERFACE the anonymous block gets parsed/validated and the statement is executed. But this
time the block does a normal "connect session" and the trigger is fired. This means the statements accesses the T1 table in
schema DATA. (But T1 in INTERFACE has to be existent that parse/validation works)
I don't know if this is a bug or a feature.
To workaround this I have created private synonyms in schema INTERFACE pointing to the objects in DATA.
Thanks for your help!

regarding the other qestion:
Yes, permissions are granted over a role.

mh... had to add

to the Monitor section for rotation to work. Adding it to the device section did not work. Can any1 confirm that, cause arch-wiki still says to add it to the device section.

Usb stick not working (solved)

I copied some files to my usb stick and made sure it was working. Then I copied a open office file from my wifes computer running vista. After placing the usb stick back into my computer I got the following message
A security policy in place prevents this sender from sending this message to this recipient, see message bus configuration file (rejected message had interface "org.freedesktop.Hal.Device.Volume" member "Mount" error name "(unset)" destination "org.freedesktop.Hal")
I went to xsessions and got the following message.
kded: ERROR: mount failed for /org/freedesktop/Hal/devices/volume_uuid_709E_ED39: org.freedesktop.DBus.Error.AccessDenied - A security policy in place prevents this sender from sending this message to this recipient, see message bus configuration file (rejected message had interface "org.freedesktop.Hal.Device.Volume" member "Mount" error name "(unset)" destination "org.freedesktop.Hal")

Seeing as the stick worked before I copied a file from vista, did the vista change something in the usb so it will not work in anything but windows? Is there anything I can do?
changed /dev/sdc1 /mnt/usb vfat noauto,users 0 0
to /dev/sdc1 /mnt/usb auto noauto,users 0 0
and now everything works fine

Kernel requirements for HPLIP (not working) [SOLVED]

My printer (connected to the network through my router with a static ip address) used to work fine with HPLIP and CUPS. When I last tested, I was (and am) using a custom-compiled zen kernel; the relevant modules that I compiled (separately, not into the kernel) are plip, ppdev, and parport. I am guessing that it is a combination of package upgrades and my custom kernel that is causing the problem below:
My printer is detected by CUPS, and I can see it on localhost:631. When I send jobs to it, it begins "processing" them, then hangs on a (to-print) page and I see the message
/usr/lib/cups/backend/hp failed
I deleted the printer from CUPS and re-added using
sudo hp-setup
The process goes just fine, with hp-setup only throwing a warning about how dbus must be running for the PC to fax (with which I am not concerned).
When I run hp-testpage, I get this:
redscare:~> hp-testpage

Report format trigger not working

Hi,
I am using a format trigger on a column in my report as follows:
function B_9FormatTrigger return boolean is
begin
if (:TEST > 30) then
return (FALSE);
else
return (TRUE);
end if;
end;
When testing in reports builder everything works fine, but when running the report from a form, the trigger is not executed.
I am thinking this might have something to do with te reports runtime, but i don't know how to solve it.
I am using Report Builder 9.0.4.0.33
Edited by: user10085365 on 3-feb-2009 6:12

so, did you try my suggestion to switch the condition?
Or, is there maybe an old rep-file in your runtime-environment which doesn't include the format-trigger? Try to colorize a field and see if the correct reports-version is run.
And I am a 100% shure the :TEST value is correct.
So the field that should be hidden, stays displayedYes, but its unlikely that you hit a bug here (but not impossible), the chance in gendral is higher that there is some other reason for that. (in my case, 99.99% of the things which don't work are my own fault ;-) )

Trigger not working correctly

Hello all.
I am working on a project, Yes it is for a class. I am creating a simple Boat rental db. I am trying to construct a Trigger that will verify when a Reservation is made for a particular date and time in the future (current day and beyond) that the Rental_Start_Time falls within the business hours for that particular date.
I have a Reservation table
CREATE TABLE RESERVATION
(res_id NUMBER (10),
req_date DATE,
renter_id NUMBER(10),
model VARCHAR2(30) NOT NULL,
rental_date DATE NOT NULL,
rental_start_time DATE NOT NULL,
rental_end_time DATE NOT NULL,
guests NUMBER(2) NOT NULL,
CONSTRAINT res_id_pk
PRIMARY KEY(res_id, req_date, renter_id, model))My trigger is as such:
CREATE OR REPLACE TRIGGER bus_hrs
BEFORE INSERT ON RESERVATION
FOR EACH ROW
DECLARE
RST DATE := :NEW.RENTAL_START_TIME;
RD DATE := :NEW.RENTAL_DATE;
BEGIN
IF ((TO_CHAR(RD,'D') BETWEEN 1 AND 5) AND
(TO_DATE(TO_CHAR(RST, 'hh24:mi'), 'hh24:mi') NOT BETWEEN
TO_DATE('12:00', 'hh24:mi') AND TO_DATE('21:00', 'hh24:mi')))
OR ((TO_CHAR(RD, 'D') BETWEEN 6 AND 7)
AND (TO_DATE(TO_CHAR(RST, 'hh24:mi'), 'hh24:mi') NOT BETWEEN
TO_DATE('08:00', 'hh24:mi') AND TO_DATE('24:00', 'hh24:mi'))) THEN
RAISE_APPLICATION_ERROR(-20999,
'Rental start times cannot be scheduled outside of business hours');
END IF;
END bus_hrs;And this is my call:
CALL make_reservation(SYSDATE,'11','pontoon' , (to_date('2012/06/15 08:00', 'yyyy/mm/dd hh24:mi')),(to_date('2012/06/15 08:00', 'yyyy/mm/dd hh24:mi')), (to_date('2012/06/15 16:00', 'yyyy/mm/dd hh24:mi')), '12');And this is the result I am seeing:
ORA-20999: Unhandled error in make_reservation. Please contact your application administrator with the following information: ORA-01850: hour must be between 0 and 23 ORA-06512: at "LAKERS.BUS_HRS", line 9 ORA-04088: error during execution of trigger 'LAKERS.BUS_HRS' ORA-06512: at "LAKERS.EXCEPTION_HANDLER", line 11 ORA-06512: at "LAKERS.MAKE_RESERVATION", line 15
In the Call I am trying to make enter a reservation for June 15 with a start time of 08:00 AM which should be an hour of 8, however the error response tells me it is not recognizing the hour.
Am I formating the Call wrong or do i have a problem within the trigger?
Thanks for taking the time to look.

Hi,
You're doing a lot of converting between DATEs and VARCHAR2s, and back again. There's no need for that.
It looks like all you need to know about :NEW.rental_start_time is the time of day. If so, convert it once for all into a form convenient to work with, such as as string like '14:30'. Likewise for :NEW.rental_date.
I think you want something like this:
CREATE OR REPLACE TRIGGER bus_hrs
BEFORE INSERT ON RESERVATION
FOR EACH ROW
DECLARE
    days_into_week     NUMBER          := :NEW.rental_date
                          - TRUNC (:NEW.rental_date, 'IW');
    rst               VARCHAR2 (5)     := TO_CHAR ( :NEW.rental_start_time
                                    , 'HH24:MI'
BEGIN
    IF (days_into_week < 5 AND rst NOT BETWEEN '08:00' AND '24:00')     -- Monday-Friday
    OR (days_into_week >= 5 AND rst NOT BETWEEN '12:00' AND '21:00')     -- Saturday-Sunday
    THEN
        RAISE_APPLICATION_ERROR ( -20999
                    , 'Rental start times cannot be scheduled outside of business hours'
    END IF;
END bus_hrs;
SHOW ERRORSDo you really need two separate columns, rental_date and rental_start_time? What are you using the hours, minutes and seconds parts of rental_date for? What are you using the year, month and day parts of rental_start_date for?
TO_CHAR (date_column, 'D') depends on your NLS_TERRITORY setting. If you ever change NLS_TERRITORY, you're probably not going to remember to change this trigger. I used 'IW' instead of 'D', because 'IW' does not depend on any NLS settings.
