One make oracle webcache cluster listening in only one URL??

I need some ideas about how make this, I have two physical machines and two webcaches in cluster, but i writte in the URL the ip of one machine or the second machine, i want writte one url and the request ca be response by webcache 1 or webcache 2. thanks any help

Success!!!
I had to grant this permissions:
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.lang.RuntimePermission', 'getClassLoader', '' );
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.lang.RuntimePermission', 'accessClassInPackage.sun.util.calendar', '' );
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.lang.RuntimePermission', 'setFactory', '' )
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.util.PropertyPermission', 'HTTPClient.socket.idleTimeout', 'write' );
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.net.SocketPermission', 'localhost', 'resolve' );
call dbms_java.grant_permission( 'WS_TEST', 'SYS:java.net.SocketPermission', '127.0.0.1:8084', 'connect,resolve' );
As I wrote earlier, WS_TEST is my user into which I load JAX-RPC client. Note that, if you load JAX-RPC client into user another than SYS, you have NOT to use -s -grant public option (wassam wrote about this too). Another thing is that I (finally) didn't load OC4J. To consume WebService I use utl_dbws.invoke(call_Handle CALL, request SYS.XMLTYPE) function.

Selecting all columns makes oracle use more indexes than only selectng one?

I have 3 queries here that differ only slightly, conceptually, but the plans are massively different. What I cant work out is that the difference is only in the select list.. The fields referenced in the where clause are properly indexed for this purpose
SELECT
scc.expiry_date
FROM
bw3.int_file_log_details ifld
INNER JOIN
bw3.svc_card_status_change scsc
USING
 (institution_number, file_number)
INNER JOIN bw3.svc_client_cards scc
USING
 (card_number)
WHERE
institution_number = '00000001' AND
file_number = '00002504'This one above does a full table scan of SCC, over 3.5 million records
SELECT
card_number
FROM
bw3.int_file_log_details ifld
INNER JOIN
bw3.svc_card_status_change scsc
USING
 (institution_number, file_number)
INNER JOIN bw3.svc_client_cards scc
USING
 (card_number)
WHERE
institution_number = '00000001' AND
file_number = '00002504'This one above does an index fast full scan of SCC's pk (which is cardnumber), as does doing a "SELECT null as dummy FROM..."
SELECT
FROM
bw3.int_file_log_details ifld
INNER JOIN
bw3.svc_card_status_change scsc
USING
 (institution_number, file_number)
INNER JOIN bw3.svc_client_cards scc
USING
 (card_number)
WHERE
institution_number = '00000001' AND
file_number = '00002504'This one above does the index range scan of the columns mentioned in the where clause and two index unique scans to link in IFLD and SCC (because they are joined on their PKs)
I would expect all queries to run this way and completes in ~0.01 seconds
Now, I get that oracle will sometimes use only an index instead of a table access when the requested data can be got from the index, but the actual query is pulling data from some columns not in indexes, so must be accessed in the table:
SELECT
scsc.card_prod_data as "Field1",
substr(card_number,1,4)||' '||
 substr(card_number,5,4)||' '||
 substr(card_number,9,4)||' '||
 substr(card_number,13,4)||' '||
 substr(card_number,17) as "Field2",
' ' as "Field3",
scc.emboss_line_1 as "Field4",
scc.emboss_line_2 as "Field5",
TO_CHAR(TO_DATE(scc.last_issued_date, 'YYYYMMDD'), 'MM/YY ')||
 TO_CHAR(TO_DATE(scc.expiry_date, 'YYYYMMDD'), 'MM/YY ')||
 ' ' as "Field6",
'B'||
 card_number||
 '^'||
 RPAD('0', 27, ' ')||
 '^'||
 to_char(to_date(scc.expiry_date, 'YYYYMMDD'), 'YYMM')||
 service_category_code||
 '000000000000' as "Field7",
card_number||
 '='||
 to_char(to_date(scc.expiry_date, 'YYYYMMDD'), 'YYMM')||
 service_category_code||
 '000000000000' as "Field8",
card_number as "Field9",
scsc.cvv_cvc2 as "Field10"
FROM
bw3.int_file_log_details ifld
INNER JOIN
bw3.svc_card_status_change scsc
USING
 (institution_number, file_number)
INNER JOIN bw3.svc_client_cards scc
USING
 (card_number)
WHERE
institution_number = '00000001' AND
file_number = '00002504'This query above, which uses some data from all tables, does a table full scan of SCC, yet if I SELECT * FROM.. I get the expected index usage and table access by index rowid for all tables..
Why is oracle doing an FTS when I choose only some columns, yet doing index access when I select * ?

Selectivity of indexes?
For a query linking these tables:
int_file_log_details <-> svc_card_status_change <-> svc_client_cards
I'm expecting Oracle to:
Use an index range scan of the index on svc_card_status_change that is a nonunique index of institution_number and file number. Selectivity of this index is:
1 institution number in the entire table
59 distinct file numbers in the entire table
4.1million records in the entire table
From there, with the records it found, to use index unique scan of the PKs of int_file_log_details (file_number: 1 record required) and PK of svc_client_cards (card_number: poetntially thousands of records required)
I can understand if oracle might decide it can get 69k records out of 4.1 million faster by FTS the cards table rather than having the indirection of the index... what I cannot understand is:
If I select all the data from the query (SELECT *) it does unique index scans for the 2 records
If I select say, only one non-indexed non-joined column from each table, oracle prefers a FTS of the cards table..
Is oracle not realising that there are only 2 records I need out of cards? Why would select * differ? Is it that oracle thinks "select * is a large amount of data, so it'll be faster to use the index and target certain rows" vs "select one_column can be garnered more quickly by scanning the table and generating a lower overall memory load" ?

Do I have to make Oracle XE listener working before I install Oracle APEX?

Hi, guys:
I have a question: Do I have to make Oracle XE listener working before I install Oracle APEX 4.2? I have installed Oracle XE 11g on windows 7, however, I got problem to run Oracle XE listener, though Oracle XE itself is running. Since my purpose is to run Oracle APEX I was wondering if I have to make Oracle XE listener working at first.
Thanks for your comments!
Sam

Hi, Jarola:
Thanks for your help! My supervisor asked us to install Oracle XE, OC4J, and APEX listener in our local PC (windows 7 64 bits). I guess his purpose is to train us to install APEX 4.2 eventually. I installed OC4J and APEX listener before without much problem; but I have difficulty to install Oracle XE on windows 7 64 bits version as so far Oracle XE only supports 32 bits windows. after I installed Oracle XE, I got these problems:
#1 the Oracle XE itself is running, but XE listener cannot work, it always reports "the Oracle OracleXETNSListener service started and then stopped, some service stop automatically if they are not in use by other services or programs.",
#2 It looks Oracle_home of XE conflicts with that of OC4J. I tried to set ORACLE_HOME as "C:\OC4J\oc4j_extended_101350;C:\oraclexe\app\oracle\product\11.2.0\server", but OC4J cannot find config file so I cannot start OC4J. it is messed up.
#3 most of all, I was wondering if you could tell me the relationship among Oracle XE, OC4J, and APEX listener regarding installing APEX 4.2, are they all necessary to install APEX 4.2? if so, could you guide me to install these things with proper steps (say, which one should be installed first?)? any of your suggestion would be very appreciated! (I have tried two weeks without progress...)

Two WebCache and one URL

Hello, I have one cluster of WebCache, but whit different ip address on diferent physical host, ?how a I can whit one URL in the brower realize load balance acrros the WebCache clusters. I not have a hardware load balancer. thanks any idea.
for other side when I try to access to one deploy application:
http://46.34.5.15:7785/benefits
obtain the following:
NOT FOUND
Sorry!the page requested was not found.
and when I try to access whit the following URL:
http://46.34.5.15:7785/benefits/welcome.html
the app work fine
Why?? i have to agree "welcome.html", if the application name is only "benefits"
Thanks any help

How could I study Oracle linux cluster ?

Hello buddy:
I want to study Oracle linux cluster. so, where can I get started ? I read online documents, but they not tell you how to build a test enviroument using VMware.
Could you give a hint ?

user1934450 wrote:
Purpose is studying.Studying what exactly? Clusters are more than just shared disks.
I want to restablish a single instance and database using OS cluster. The shared disk just can be seen by on node server, then I can manually test this OS cluster and make switching between two nodes at least.This is not really a cluster. A cluster supports scalability - for example, if a process load is too large for a single node, some of it can spill over and be executed by another node or multiple other cluster nodes.
If you talk about standard Linux clustering, that would be running some kind of number crunching s/w (weather modeling, crunching astronomy data, etc) and running this across multiple cluster nodes.
A shared cluster storage system is one possible component of a cluster.
Taking your example - a shared cluster file system is not needed. As the other nodes cannot use that file system (if it does, it can corrupt database files) - only a single non RAC database instance can use the database. Thus the file system can only be used by a single instance on a single server. No clustering needed.
When that server fails, that file system (from the storage server) needs to be mounted on another server and the database instance started on that server.
This is not really a true cluster - simply a high availability and redundant configuration using multiple servers.
If you want to study actual real clustering - do some research using Google. Create a simple project like calculating pi for example and create a virtual 2 or 3 node cluster that run this processing in parallel - using a shared cluster file system for data storage.

How can I make a book/podcast listening playlist for a blind person?

How can I make a book/podcast listening playlist for a blind person? How can lots of content be loaded, so that no navigation is required, for hundreds of hours of enjoyment?
I wanted to create a single playlist with hundreds of hours of books and podcasts for my grandmother who is blind. Then I planned to use something like the app CarTunes which basically makes the touch screen simply a gigantic pause/play button for an already created playlist. This is perfect for a blind person. The problem: Apple no longer allows you to have a playlist with Audible Books and Podcasts. I have tried; but the podcasts and books are stripped from the playlist. It seems like all podcast and book players require navigation. (How aggravating!?)
Any help in creating hundreds of hours long spoken (selected between books and podcasts) audio content playlist for a blind person would be much appreciated!!!!

Well, good news and bad news. I found out how to tell iTunes that all my music videos are, in fact, actual "music videos" and categorize them as such. In the "Get Info" screen for a track, there is a dropdown selector where you can pick the "meta" type, such as "Music Video", "Home Video", "Movie", "TV Show", etc. This allows iTunes and iOS to think they are all music videos and play them in the same list.
Unfortunately, this is not compatable with my third party device, which is now refusing to play my music videos in a playlist and will only play them one at a time (in a single-track infinite loop no less). Very frustrating!

Oracle Workflow WF_IN Listener doesn't dequeue message


I'm using Oracle Interconnect 10g (ver. 10.1.2.2) and has been struggle trying to make the workflow WF_IN listener to work and have no luck so far.


I have done the following: 
1. Create a Service Components for Workflow Inbound Listener from Oracle Application Server Control 10g. 
2. Create WF_IN Listeners from Oracle Workflow Setup Check All homepage 
3. Create 3 Event Subscriptions from Oracle Workflow homepage: 
a. Event: oracle.apps.wf.event.agent.create 
b. Event: oracle.apps.wf.event.event.create 
c. Event: oracle.apps.wf.event.subscription.create 
4. Create Oracle Workflow Publish and Subscribe Activity Event from iStudio and deploy them to Oracle Workflow


Regardless, the message that is in WF_IN Queue is always in ready state (state 0) and never dequeued. I have no idea what steps am I missing here. It just seems that the listener I created doesn't work or maybe not configure properly. So, if anybody can help me out here, I really appreciate. Here is the screenshot of the configuration I mentioned above.

Thanks,
 
Edward


Edward, you see, when you create WF_IN Listener from Oracle Workflow Setup Check All homepage, really they implemented as database JOBs.
So, connect to database as sys and select from DBA_JOBS, look if there is any job with text ("what" column) like "Wf_Event.Listen('WF_IN')".
If there is one or several - check there status, if they are working correctly (broken = 'N', failures = 0).
If broken = 'Y' or failures > 0, than you have problems with them!
In this case check if you have set database parameters job_queue_processes=10, and aq_tm_processes=1 as recommended for Workflow.
If it does not help, try to execute dequeue comment manually:
begin
Wf_Event.Listen('WF_IN');
end;
Good luck!

How to use one URL for several Oracle AS?

Hi folks,
how do I use one URL to access several application servers (i.e. for different applications).
Example:
We have one URL:
www.test.com
In our DMZ, wie have three application servers and one web cache:
test1.intranet.com:7777
test2.intranet.com:7777
test3.intranet.com:7777
webcache.intranet.com:8000
One application server is no problem. In Web Cache, i just map site www.test.com:443 to AS test1.intranet.com:7777.
But what is the correct setting, to access all three Oracle AS over one URL? I tried URL PATH Prefix. Then i am able to access all three Oracle AS, but the application server does not know the Path.
Example for mapping:
www.test.com:443/server2 -> test2.intranet.com:7777
When I access www.test.com:443/server2, I get redirected to the correct AS (test2.intranet.com:7777), but the Oracle AS does not know the path /server2.
How do I have to configure the Oracle AS?
Thanks in advance and best regards.

I setted up a proxy and at first glance,
it works fine. The problem are internal links. Some links redirect to the
machine name, which is of course not accessible from outside our dmz.
My httpd.conf entries:
ProxyPass /test1infra/ http://test1.intranet.com:7777/
ProxyPassReverse /test1infra/ http://test1.intranet.com:7777/
ProxyPass /test1mid/ http://test1.intranet.com:7778/
ProxyPassReverse /test1mid/ http://test1.intranet.com:7778/
When I now access (for example) www.test.com/test1infra/pls/orasso I get
redirected to www.test.com/pls/orasso, which is another Oracle AS!
How can I prevent my OracleAS doing this? It has to "know" that all its internal urls need a url path prefix.

How do I set a Phase Listener to only run for a specific page?

How do I set a Phase Listener to only run for a specific page?
I understand that a Phase Listener runs for ever page in the application, however I want a phase listener to only run for one page at the beginning of the application.
I discovered I can't use a Filter, because the JSF Application instance always returns null.
Thus, I thought a Phase Listener would be a good approach.
Thoughts?
Thanks,

I have moved forward with checking the requested URI...

Bug in oracle embedded http listener

Hi there,
I've discovered a bug in the Oracle embedded http listener for our Oracle on RHEL database version 11.1.0.6 where it will return HTTP-400 bad request errors if a cookie is created with a bare comma in the cookie value. To see for yourself, simply create an apex application with an open door authentication and enter a username with a comma in it - page 101 writes the username to a cookie, and then you get HTTP-400 errors.
I'll raise this as a bug at Oracle, but in the meantime I'm frantically trying to figure out a workaround. We have a production site using a standard Apache frontend that we link to Apex applications using mod_rewrite. There are other applications on the site (invision powerboard) which create cookies with bare commas, so we have no control over the creation of these maligned cookies. My thinking is that we might be able to use mod_rewrite rules to weed out the offending cookies and encode the commas so that things continue to work.
Can anyone assist with a workaround?
Many thanks,
Mike

Hi Mike,
perhaps you can try to modify the cookies on the client?
http://scripts.franciscocharrua.com/javascript-cookies.php
Or is it already too late so that you cannot even run the first procedure to inject the javascript code into the first page?
Or, you could configure the DAD to run a stored procedure before anything else:
PlsqlBeforeProcedure
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_epg.htm
If this is already too late, your only option seems to be to use an Apache as a proxy and modify the cookie value there.
Regards,
~Dietmar.

This is an error from my HP scanner. How can I fix the problem? An error has occurred saving the file because it could not be written to. Check the properties for the file to make sure it is not read-only.

I recently uploaded the Maverick operating system. I wanted to scan some things on my HP Printer/Scanner and could not . This is the error message I received: An error has occurred saving the file because it could not be written to. Check the properties for the file to make sure it is not read-only. I am a novice with the computer and have no one to help. I hope someone knows an easy fix.
Thank you

This worked for me:
"Although it is not a 'fix' for the HP issue, I did find a workaround that helped me. In the Preferences Panel in MacOS X you can pull up the Printer/Scanner preferences and scan directly from OS X. I'd not known of this prior to posting here and it worked like a charm."
"Of course, HP should still update their software, but it's good to know that Apple has it covered for them."
I found it here:

Private interconnect of an Oracle 10g cluster

Can you please answer below questions?
Is a direct connection between two nodes supported on the private interconnect of an Oracle 10g cluster?
We know that crossover cables are not supported, but what about a Gigabit network with a straight cable?”

Hi,
I really wouldn't suggest that approach, It is definitely not efficient and not flexible
- If you have 4 nodes, and nodes 1 want to send message to node 4, the package must go through node 2 and 3? Is it efficient? NO absolutely
- If you have e.g 2 nodes, if one of the link down in one of the nodes, the other nodes link will also down, this will most likely evicting both nodes instead of one node
- your clusterware nodes iis limited by the cable which is not efficient
- etc etc etc more disadvantages than advantages
Cheers

BUG: External Subversion Repository, Can only connect to one URL unless....

Jdeveloper 11.1.1.6 and Jdevevloper 11.2.2 versions.
To See video about this "bug" please see http://youtu.be/Dp0laSTnSo4 (I made the video after writing this).
Use-case: I work on four or five different applications and need distinct repositories for each. I am able to create distinct repositories using the Jdeveloper "create Local Repository" built-in functionality, and then when I "Version Application" I see all the repositories I have created.
HOWEVER Using an External SVN as described in http://www.oracle.com/technetwork/articles/adf/part1-090228.html
I have created two repositories: app1 and app2
When I try to "version [an] Application" I can add only one URL of an external SVN, and am not able to add any others.
If I look at the repositories.xml file as found in the system directory, I see the following:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<svn-repositories xmlns="http://xmlns.oracle.com/jdeveloper/1013/svn/repositories">
<svn-repository>
<url>https://stuart-pc:8080/svn/App1</url>
<alias>App1</alias>
<user-name>hr</user-name>
<password>Bb8W5J9eNtvA1jlqkYoTNWA=</password>
</svn-repository>
</svn-repositories>
If I hack this file and add the extra lines below (with jdeveloper closed), I am able to version an application to the "App2" repository.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<svn-repositories xmlns="http://xmlns.oracle.com/jdeveloper/1013/svn/repositories">
<svn-repository>
<url>https://stuart-pc:8080/svn/App1</url>
<alias>App1</alias>
<user-name>hr</user-name>
<password>Bb8W5J9eNtvA1jlqkYoTNWA=</password>
</svn-repository>
*<svn-repository>*
*<url>https://stuart-pc:8080/svn/App2</url>*
*<alias>App2</alias>*
*<user-name>hr</user-name>*
*<password>Bb8W5J9eNtvA1jlqkYoTNWA=</password>*
*</svn-repository>*
</svn-repositories>
I think this is a bug. Since you can create multiple "local" repositories, you should also be able to this with an external repositories. Also, one should be able to add as many external URLs as necessary in the Jdeveloper GUI, since we may work on multiple applications throughout the course of a day.
Thank you,
Stuart
Edited by: Stuart Fleming on Sep 9, 2012 7:03 PM

Frank,
Thank you. Actually, I wasn't completely sure it was a bug, but it seemed that if you could do it using the "Create Local Repository" the functionality ought to be there for the external Subversion.
Just curious, would you know what the Oracle Fusion Developers use for their Repository? might they also use Maven? Hudson?
I always appreciate your help!

Oracle 10g DB listener does not work.

I am in a terrible situation.
My oracle 10g db listener often hang without any sign.
For example , sometimes user sql select one minute ago , then the database could't be conected next minute .
Even i command lsnrctl stop and start , the listener is over .
I have to kill process then start listener.
I try to find out what for , but i am don't know how to do .
May any one tell my why or how ?
Thank you .

Thank you .
I find how to happen the problem . It should be bug 4518443 .
Now i have another question .
I want to apply patch ,but fails.
following is my command line :
[oracle@localhost ~]$ opatch lsinventory
-bash: opatch: command not found
When I cd $oracle_home/OPatch , i find opatch file.
Iam not sure why i can't apply patch .
Thak you .
