Examples
The following example illustrates how UTL_SMTP is used by an application to send e-mail. The application connects to an SMTP server at port 25 and sends a simple text message.
DECLARE
c UTL_SMTP.CONNECTION;
PROCEDURE send_header(name IN VARCHAR2, header IN VARCHAR2) AS
BEGIN
UTL_SMTP.WRITE_DATA(c, name || ': ' || header || UTL_TCP.CRLF);
END;
BEGIN
c := UTL_SMTP.OPEN_CONNECTION('smtp-server.acme.com');
UTL_SMTP.HELO(c, 'foo.com');
UTL_SMTP.MAIL(c, '[email protected]');
UTL_SMTP.RCPT(c, '[email protected]');
UTL_SMTP.OPEN_DATA(c);
send_header('From', '"Sender" <[email protected]>');
send_header('To', '"Recipient" <[email protected]>');
send_header('Subject', 'Hello');
UTL_SMTP.WRITE_DATA(c, UTL_TCP.CRLF || 'Hello, world!');
UTL_SMTP.CLOSE_DATA(c);
UTL_SMTP.QUIT(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
BEGIN
UTL_SMTP.QUIT(c);
EXCEPTION
WHEN UTL_SMTP.TRANSIENT_ERROR OR UTL_SMTP.PERMANENT_ERROR THEN
NULL; -- When the SMTP server is down or unavailable, we don't have
-- a connection to the server. The QUIT call will raise an
-- exception that we can ignore.
END;
raise_application_error(-20000,
'Failed to send mail due to the following error: ' || sqlerrm);
END;

Cloud Control 12c monitoring Oracle 11g Standard Edition alert.log
Hi guys.
I just installed Cloud Control 12c3 and added my cluster database, I have readed many papers, tech docs and tech discuss and now i have a huge confussion about packs, licensing and other fruits. Please help...
I have four Oracle 11g databases (differents hosts) Standard Edition, and i want monitoring and notificate alert.log errors. For example, if alert.log says "ORA-01438, blablabla" i want a email notification.
I read about packs, and says that "diagnostic pack" is needed for alert.log monitoring in Cloud Control 12c. But my version database is Standard Edition without packs, so I CAN'T MONITORING ALERT LOG!!!.
Question:
Do I really need Diagnostic Pack for monitoring alert.log with Cloud Control?
If Diagnostinc Pack is not necessary, how can i monitoring alert.log?
ThanksI do not think you require any pack for alert.log content monitoring but you might need to check with Oracle rep. I am saying so because if you go to the "Alert log content" page and click on management pack for this page, Grid will display a message that this page does not require any pack.
Go to the Alert log content by "oracle database -> logs -> alert log contents"
then
go to SETUP -> management packs -> packs for this page
You will see the message will be displayed " this pages does not require any pack"
Can you also provide the doc where it says that this pae needs diagnostic pack? -
ACL error when sending email from Oracle 11g
Hi,
It returned something like "error...ACL security" when I tried to send email from Oracle 11g. Is there any security thing that I need to release in Oracle 11g? I used to send emails from Oracle 10g and didn't find any problem.
Thanks.
AndyIn Database 11g Oracle introduced Network Access Control Lists (ACLs) to protect the database from users using the many internet-capable packages such as UTL_INADDR, UTL_HTTP, UTL_TCP, etc.
Read all about it in the docs and look at the code demos here:

Starting BPEL when email received - Oracle 11g
I'm trying to start a BPEL Process with the reception of an email.
- I'm working with Oracle 11g
- Usermessagingserver is installed and configured to the correct server and it's working, at least it shows received emails and it's able to send emails from a BPEL process
In the BPEL that has been done to start with the reception of an email I have the following:
<partnerLink myRole="Consume_Message_role" name="Inbound" partnerLinkType="ns1:Consume_Message_plt"/>
Inbound_jms.jca has the following configuration:
<adapter-config name="Inbound" adapter="Jms Adapter" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/wls/Queue" UIConnectionName="soa-server" UIJmsProvider="WLSJMS" adapterRef=""/>
<endpoint-activation portType="Consume_Message_ptt" operation="Consume_Message">
<activation-spec className="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec">
<property name="DestinationName" value="OraSDPM/Queues/OraSDPMEngineRcvQ1"/>
<property name="UseMessageListener" value="true"/>
<property name="PayloadType" value="BytesMessage"/>
</activation-spec>
</endpoint-activation>
</adapter-config>
When usermessagingserver receives an email message, the BPEL doesn’t start and I get this message in the log:
PM oracle.sdpinternal.messaging.EngineReceivingCoreBean processMessageCommon
WARNING: There is no application that has registered this address as an access point. Message will not be delivered.
I have no idea how to configure an access point, I've only found how to De-register from Messaging Client Applications in the usermessagingserver.
Found this documentation about registering access points, from an sample application of usermessaingserver in [http://download.oracle.com/docs/cd/E12839_01/doc.1111/e13807/ns_java_api.htm|http://download.oracle.com/docs/cd/E12839_01/doc.1111/e13807/ns_java_api.htm]
but I cannot find where to download the example from the documentation.
Any help appreciated.Does anyone has some input on this issue?
I want to do the same thing, but I don't know how to...
Thanks -
Sending email from apex 4.0 with oracle 11g ee
Hi,
I the past when working with apex 3 I was able to work with apex mailsend very nice.
In apex 4.0 with oracle 11g ee I'm not able to send emails anymore.
Last error message in the queue is:
ORA-29279: SMTP permanent error: 550 through this server without authentication.
the smtp server has not been changed, the code is fine
How I can go further?
Many thanks,
FlorinThis is a different subject:
Apex Reports and links to external content
What you are asking should be possible.
Risk: everyone who uses the link needs to have the same drive mapping if you are using letters on a Windows PC. As long as that is not a usability issue, you are fine.
I would recommend you review the LINK syntax in the report column.
Your text seems like you have already attempted this.
>
Click Here , i.e. href="file:///E:/Echo Destination/1212040003.docx"
. . . . . . . from XYZ
Here I am unable to open this document via click on this column link on report............
Thanks..To confirm the link syntax you want first, Write a simple HTML file with the link to make sure you have the correct quoting and the link content is correct.
What does the REPORT resulting HTML look like when you examine it on the page?
I would expect something like:
<a href=file:///E:/Echo Destination/1212040003.docx> go to file </a>If the result is different, then we can discuss why it isn't what you are expecting.

Configuring email alerts in Ops Center
Hi all,
I have been struggling quite a while to get email alerts working from Ops Center with no success in 11g nor 12c. In the Ops Center GUI, Administration -> EC -> Local Users -> configured user to receive all alerts and emails. I have also configured email relay host correctly(checked a million times).
Sending emails from the host through the email relay works fine, so I'm baffled.
#mailx -s " Test from Ops Center" "my.email@work" < text-file
Do I need to configure something else in Ops Center or what am I missing here?The email alerts from Ops Center are working for me, I performed...
1.) You must be able to send email from the command line on the Enterprise Controller to the intended email address, ie;
# mailx -v [email protected]
Subject: Email test from Enterprise Controller
EOT
<control-d>
That test must be successful, and the email received!
2.) Setup the Notification Profile in the BUI...
Administration > Enterprise Controller > Users
Highlight the root user, select Configure Notification Profile (the wrench icon)
Notifications via >> Subscribe to All Notifications
User Interface > "Problem updates and all Severities"

Notifications Delivery Details
Email: [email protected]
Pager Address: <blank>
Mail Host: localhost
Port: <blank>
Mail User: root
Mail Password: <enter the password for root on the EC>

Select: Update Notification Profile
3.) Go to Assets > Operating System (second level down) of some Asset
In the center pane select the "Monitoring" tab
Under "Threshold Monitoring Rules" highlight "Memory Usage Percentage"
Edit Alert Monitoring Rule Parameters (the pencil)
Monitor for alert limits continuously
Toggle: Generate Alert after 1 Minute
Change Critical MemoryUsage.usedMemoryPercentage > 2%
Change Warning MemoryUsage.usedMemoryPercentage > 1%
Apply
Wait one minute, you should receive an email that resembles the following:

Installation of Oracle 11g Release 2 on Windows Server 2008 R2
Hi:
When I tried to install 64-bit Oracle 11g Release 2 on a system running 64-bit Windows Server 2008 R2.
One of the system pre-requisites failed with the following error message:
Checking operating system requirements ...
Expected result: One of 5.0,5.1,5.2,6.0
Actual Result: 6.1
Check complete. The overall result of this check is: Failed <<<<
Problem: Oracle Database 11g is not certified on the current operating system.
Recommendation: Make sure you are installing the software on the correct platform.
I presume 6.0 is Windows 2008 Server and 6.1 should be Release 2.
Does this mean that this version is not compatible with Server 2008 Release 2?

No one inside Oracle is permitted to say, or pre-announce release dates for legal reasons.
Which is why I gave you the link - so you could monitor for yourself.OK, thanks...
I was just hoping there was an official release date and I just couldn't find it.
Is there any information about features in 11gR2 for Windows available yet?
Or can you maybe tell me if it will be possible to mount the new "database filesystem" like we can do on linux?
I remember oracle did something similar with Oracle ifs (Internet File System) back in Oracle 9i. (or was it 8i?)

Oracle 11g RAC on CentOS 5.2 - Node isnt working after hardware failure
Hi,
We have a 2-node Oracle RAC 11g running on identical nodes with Centos 5.2 as operating system.
Due to a drive failure and a reboot yesterday, the ASM disk, which is onnected via iSCSI, changed from sdd to sdc in name - (the faulty raid drive was removed, thus the change).
The oracle services didnt start, which appeard perfectly logical at the time, given that the ASM disk suddenly wasnt where it was supposed to be, but even today after a replacement disk was inserted, the RAID rebuilt + with the ASM disk back to its original naming in /dev/; the node doesnt seem to work properly. Some of the oracle services are running, but there seems to be a problem with the listener, which might also explain why the node does not set it's virtual ip after starting up.
Luckily, the other one is unaffected and is working perfectly fine..
I'm far from having a clue about oracle, it was sheer luck (that, and the very usable documentation by oracle) that i managed to get that cluster running in the first place... I know my way around linux, so if it's a operating system related problem i'll be able to fix it, but i cant figure out what the problem with oracle is.
The listener doesnt seem to be running

Edited by: user9134821 on 08.06.2010 02:39Hi,
As usual, as soon as i post a problem in some board, i find the solution myself.
Although this way isnt really "linuxy", deleting the listener with the netCA tool and adding a new one solved it.

The danger of memory target in Oracle 11g - request for discussion.
Hello, everyone.
This is not a question, but kind of request for discussion.
I believe that many of you heard something about automatic memory management in Oracle 11g.
The concept is that Oracle manages the target size of SGA and PGA. Yes, believe it or not, all we have to do is just to tell Oracle how much memory it can use.
But I have a big concern on this. The optimizer takes the PGA size into consideration when calculating the cost of sort-related operations.
So what would happen when Oracle dynamically changes the target size of PGA? Following is a simple demonstration of my concern.

alter session set events '10053 trace name context off';With above test case, I found that
1. Oracle invalidates the query when internal pga aggregate size changes, which is quite natural.
2. With changed pga aggregate size, Oracle recalculates the cost. These are excerpts from the both of the 10053 trace files.

Bug Fix Control Environment10053 trace file clearly says that Oracle recalculates the cost of the query with the change of internal pga aggregate target size. So, there is a great danger of unexpected plan change while Oracle dynamically controls the memory segments.
I believe that this is a desinged behavior, but the negative side effect is not negligible.
I just like to hear your opinions on this behavior.
Do you think that this is acceptable? Or is this another great feature that nobody wants to use like automatic tuning advisor?

(I'm still in dark age on this automatic memory target management of 11g. More research in need!)
I think that this is very clear and natural behavior. I just want to point out that this would result in unwanted catastrophe under special cases, especially with some logic holes and bugs.

How to Install oracle 11G Solaris 10 NO GUI using command line
Hello
I need to install oracle 11G R2 on Solaris 10 but cant use interactive mode i tried the following
/runInstaller -silent -force -debug FROM_LOCATION="/var/tmp/oracle/database/stageproducts.xml" ORACLE_HOME="/oracle/product"
As per oracle metalink documentation - however i get the following messages

has anyone installed oracle with no interactive mode how can i do so ?
thank youHave you followed the needed steps in the Install Guide ? http://download.oracle.com/docs/cd/E11882_01/install.112/e17163/app_nonint.htm#BABFEECI

Writing request XQUERY with oracle 11G
Hi,
What is exactly the best way to make an XMLTYPE object (column with type XMLType) request with Oracle 11 g ? (Oracle 11g Release 11.2.0.3.0)
In different books, we see a lot of different requests.
Simple example :
create table contact_file_tbl(filename varchar2(255), xml xmltype);
insert into contact_file_tbl (filename, xml)
values ('john_smith.xml', xmltype(bfilename('XML_DIR', 'john_smith.xml'),nls_charset_id('AL32UTF8')));
Ok for now
But impossible to make a good query :
select XMLQuery('declare namespace book="http://xmlbook.com/sample/contact.xsd"; (:
for $c in /book:contact
return $c/book:first_name' PASSING a.xml RETURNING CONTENT)
from contact_file_tbl a;
returns nothing.
why this request works ?
SELECT filename, XMLQuery('toto'
PASSING xml RETURNING CONTENT) dataResult
FROM contact_file_tbl;
Could you send me a request with this example.
Here the XML document :
<?xml version="1.0" encoding="UTF-8"?>
<contact xmlns="http://xmlbook.com/sample/contact.xsd" id="1">

1. I made System DNS mikeacs (using c:\windows\sys_wow6\odbcad32.exe) to my access mdb file;
2. I made initmikeacs.ora file in ora_home\hs\admin folder:
# HS init parameters
HS_FDS_CONNECT_INFO = mikeacs
HS_FDS_TRACE_LEVEL = debug
HS_FDS_SHAREABLE_NAME = c:\Windows
3. Listener.ora file is:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\Oracle\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
(SID_DESC =
(SID_NAME = mikeacs)
(ORACLE_HOME = c:\oracle\product\11.2.0\dbhome_1)
(PROGRAM = dg4odbc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = cspo02)(PORT = 1521))
4. Tnsnames.ora is:
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
MIKEACS =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=cspo02)(PORT=1521))
(CONNECT_DATA=(SID=mikeacs))
(HS=OK)
5. After this, I restarted Listener:
lsnrctl stop;
lsnrctl start;
Given feedback:

The command completed successfully
6. I created db link: create public database link macs using 'MIKEACS' (connected as sysdba);
7. tnsping mikeacs:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=cspo02)(PORT=1521)) (CONNECT_DATA=(SID=mikeacs)) (HS=OK))
OK (0 msec)
Then, when I try fire query (connected as sysdba): select * from mytable@macs;
get result:
ERROR at line 1:
ORA-28513: internal error in geterogeneous remote agent
ORA-02063: preceding line from MACS;
Although, when I fire the same query, but connected as other user, get next result:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][ODBC Driver Manager] Data source name not found and no default
driver specified {IM002}
ORA-02063: preceding 2 lines from MACS
Where is my problem? Please help. Thanks in advance!That's the problem. DG4ODBC on 64bit Windows is 64bit and thus it also requires a 64bit ODBC driver.
If you don't find one - maybe you can install DG4ODBC 32bi on a 32bit platform (please do NOT install it on the 64bit Windows machine) and then use this 32biit DG4ODBC with the 32bit ODBC driver.
Another option would be to purchase a commercial ODBC driver or a bridged ODBC driver. -
Oracle 11g/R2 Query Result Cache - Incremental Update
Hi,
In Oracle 11g/R2, I created replica of HR.Employees table & executed the following statement (+Although using SUM() function is non-logical in this case, but just testifying the result+)
STEP - 1
SELECT /+ RESULT_CACHE */ employee_id, first_name, last_name, SUM(salary)*
FROM HR.Employees_copy
WHERE department_id = 20
GROUP BY employee_id, first_name, last_name;
EMPLOYEE_ID FIRST_NAME LAST_NAME SUM(SALARY)

In the execution plan of STEP-3, against ID-1 the operation RESULT CACHE is shown which shows the result has been retrieved directly from Result cache. Does this mean that Oracle Server has Incrementally Retrieved the resultset?
Because, before the execution of STEP-2, the cache contained only 2 records. Then 1 record was inserted but after STEP-3, a total of 3 records was returned from cache. Does this mean that newly inserted row is retrieved from database and merged to the cached result of STEP-1?
If Oracle server has incrementally retrieved and merged newly inserted record, what mechanism is being used by the Oracle to do so?

Edited by: 965300 on Oct 15, 2012 12:25 AMNo, the RESULT CACHE operation doesn't necessarily mean that the results are retrieved from there. It could be being
written to there.
Look at the number of consistent gets: it's zero in the first step (I assume you had already run this query before) and I would
conclude that the data is being read from the result cache.
In the third step there are 4 consistent gets. I would conclude that the data is being written to the result cache, a fourth step repeating
the SQL should show zero consistent gets and that would be the results being read.
