Can a single Weblogic server host more than one Apex Listener?

Hi All:
Is it possible to deploy more than one APEX listener on a Weblogic server to service multiple APEX installations on different Database hosts?
I suspect it is just a matter of port configuration and deployment naming but has anyone experience with this?
Regards,
David

Hi David,
it is possible to have multiple instances of the APEX Listener deployed on the same JEE container. I didn't actually do this with WLS, but I don't know any reason why this should be different on WLS than it would be on other JEE containers.
You should start by preparing the apex.war to have the parameter config.dir set in the web.xml . We chose to let it point to a base directory for all config files having one subdirectory for each deployed instance, so we have to do this only once with every new release that comes in. By the way, this is the first location of the sequence to be checked by the APEX Listener upon startup.
Then you can deploy this war file multiple times giving each instance a different application name/context root. We chose +<apex_dbname>+ as pattern for this, but that's up to you.
Note that you may have to provide the static files ("images") for APEX multiple times as well if you don't have the same APEX version on each instance or if you use different custom files that shall not be the present on each instance or in different versions for at least some instances.
In that case, you'll have to configure your WLS to provide multiple "images-applications" as well. We chose to have one for each instance and use +</i_<dbname>/+ as pattern here. If you used the default image prefix +/i/+ so far, you can reset it using the corresponding script provided in the APEX installation package. I'd recommend to use the script version of the package that corresponds to the APEX version of the instance you want to configure.
That might sound complicated, but actually it's not. It's just a few things to keep in mind before starting and once you've set it up, it's really easy to handle.

Can you host more than one site on one webBasic account?

Can you host more than one site on one webBasic account?

Hi,
Basically not how this was intended for.
You'll have the option to have a partner account which you can create various sites within your portal where each site will be under its own plan.
Or you'll have an existing account which is designed for one site. So I would say ideally no but you could add multiple domains to a site account under one plan, but then you'll need to share the same account (meaning one shop, one set of system messages, layout, etc).
Those are the options at this stage.
Hope this helps!

Can I have Apple TV on more than one tv?

Can I have Apple TV on more than one tv and can I use one netflix subscription on both tvs (connected to Apple TV)?

You'd really need one AppleTV per TV - as for Netflix check your subscription package, in UK I can play on 2 devices with my current subscription or 4 for a higher fee.
AppleTv only has a single video out, so even if you relay the output of AppleTV to 2 TVs it would show the same content.

What does "sucessful" mean in this case? Does is mean producing the right results? What are the right results? How can you tell them apart from the wrong results?
As the errror message says, the (immediate) problem is that a single-row sub-query is returning more than a single row. If the sub-query tries to bring back more than 1 row, which one do you want to use? Or do you want to use some kind of aggregate, such as the average, which might not be the same as any of them?
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Simplify the problem as much as possible. For example, remove all columns and tables that have nothing to do with the part you don't know how to do.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

ORA-01427: single-row subquery returns more than one row

Hi,
Welcome to the forum!
Whenever you have a question, please post some sample data, so that people can re-create the problem and test their solutions.
CREATE TABLE and INSERT statements, like the ones below, are great:
CREATE TABLE      baemployee
(     employee     NUMBER (4)
,     stock_nbr     VARCHAR2 (10)
INSERT INTO baemployee (employee, stock_nbr) VALUES (1234, 'FUBAR');
CREATE TABLE     employee
(     employee     NUMBER (4)
,     emp_status     VARCHAR2 (10)
INSERT INTO employee (employee, emp_status) VALUES (1234, 'ACTIVE');CREATE TABLE AS is good, too:
CREATE TABLE     emp_check_dig
AS          SELECT 1234 AS employee, 'AA1234567890ZZZ' AS check_digit     FROM dual
UNION ALL     SELECT 1234,            'AA2121212121ZZZ'               FROM dual
;Also post the results you want from that data. In this case, the results would be the contents of the baemployee table after you run the UPDATE.
Would you want:
employee stock_nbr
1234       1234567890or would you want
employee stock_nbr
1234       2121212121If you run the UPDATE statement you posted with the data above, you'll get the "ORA-01427: single-row subquery returns more than one row" error, and you can see what causes it: there is more than one row from emp_check_dig that could be used to UPDATE the same row of baemployee. Say what you want to do in this situation (and why), and someone will help you find a way to do it.

ORA-01427: single-row subquery returns more than one row -- no solution

Hello to all:
I have to tables:
Table a anwender (Email,Dept). --> all fields are filled
Table b dingo (Name,email,dept) --> all fields are filled
I now want to update the table a with the data from table b:
update anwender a set a.abteilung = ( select distinct b.abteilung from dingo b where b.email = a.email);
Then I got the error: ORA-01427: single-row subquery returns more than one row
Every dept is about 100x in the database, so it is clear that i got more than one row back. But how can I update the table now?

Okay, I got several duplicates, and I deletet a lot of data in my database.
Now I want to remove all entries with more than one departments per mail adresses.
a
select email,count(abteilung) from dingo group by email having count(abteilung)>1 order by count(abteilung)
shows me all the fake mailadresses.
But a
delete from dingo where email in (select email,count(abteilung) from dingo group by email having count(abteilung)>1 order by count(abteilung) );
gives me a
SQL Error: ORA-00907: missing right parenthesis
I´m very confused now ...
Oops, now I got the solution:
delete from dingo where email in (select email from (select email,count(abteilung) from dingo group by email having count(abteilung)>1 )) ;

How can a file be accessed by more than one app?

Hi,
I am new to iOS4 and the whole iPhone, iPod technology. I am really a windows user.
How can a file be accessed by more than one app. In my case I want to transfer a midi file from my PC to my iPod Touch and be able to open it from a couple of Midi Players which I am evaluating - or does each Midi Player have to import the file seperately for its own use?
Thanks,
Sam

It seems to me that what you want is exactly a session bean will do. The EJB container is responsible to maintain a certain number instances (configurable) of your session bean and serve multiple clients at the same time. Session beans are not necessarily destroyed after serving a client. If you configure your ejb server to have a pool size of 2 to 100, then you will always have at least 2 instances (no more than 100 even there are a lot of client access) of this ejb ready to serve. The only thing not clear to me is that do you want to use only ONE instance of this bean or you don't care as long as multiple clients can access this bean's service? Since you mentioned that there is not a real database access, you can certainly use a Singleton but a 'regular' session bean with static fields should do it also if these fields will not be modified by clients.

Update gives "single-row subquery returns more than one row"

Hi,
I have to update a table by getting values from two other tables. While doing that the inner query returns more than one value. I am not sure how to implement the logic without returning more than one row in sub quesry. Need help on that.
My query:
update buf_office_str o
set o.manager_ident =
(select sp.ident
from se2_r_src_sourceperson sp ,
(select distinct director_name, team_name from buf_sales_dump )t
where SP.SRCNAME = upper(substr(t.director_name,instr(t.director_name,' ')+1,length(t.director_name))||', '||substr(t.director_name,1,instr(t.director_name,' ')-1 ) )
and o.office_descr = t.team_name
Basically the query gets teh manager id from sp table where sp.srcname = t.team-name.
The office descr should be equal to the team_name.
This is the logic I am working towards:
For each office, i get the office_descr and get corresponding team_name. Match the team's director_name (from table t) with the sp.name and return the employee's id (sp.ident) for that office_descr.
I need to update all 50 offices with corresponding managerid for that office in buf_office_str table.
Is it possible to get done in one update? Pls let me know.

Hi,
"Single-row subquery returns more than one row" is one of those error messages that actually means what it says: the correlated sub-query in your SET clause is sometimes returning 2 or more rows .
The solution could be as simple as making the sub-query SELECT DISTINCT , as its in-line view, t, already is.
It's possible you have bad data, or a mistake in your statement.
To find the problem cases, you can run something like this:
WITH sub_q     AS
                   SELECT -- DISTINCT ?
                            sp.ident
                   ,         t.team_name
                   ,         COUNT (*) OVER (PARTITION BY t.team_name)     AS cnt
                   FROM    se2_r_src_sourceperson     sp
                   ,         ( SELECT DISTINCT director_name
                               ,                  team_name
                           FROM            buf_sales_dump
                         )                    t
                   WHERE   sp.srcname     = UPPER ( SUBSTR ( t.director_name
                                                     , INSTR ( t.director_name
                                              ) + 1
                                            , LENGTH (t.director_name)
                                      || ', '
                                      || SUBSTR ( t.director_name
                                                      , 1
                                               , INSTR ( t.director_name
                                                    ) - 1
SELECT     o.*     -- or whatever helps you
,     sq.*
FROM     buf_office_str     o
JOIN     sub_q          sq     ON     o.office_descr = sq.team_name
WHERE     sq.cnt          > 1
;If you'd like more help, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables as they exist before the UPDATE, and the results you want from that data (that is, the contents of buf_office_str after the UPDATE). Make sure the problem occurs with the sample data you post.

Single-row subquery returns more than one query

Hi,
i'm receiving the following error: Single-row subquery returns more than one query. I have no idea how I should debug this query. For all I know, the subqueries can only return 1 row... :S
I only have Oracle SQL Developer to run/test my queries. I can run the query with ROWNUM < 5000, which gives no errors. If I run with ROWNUM > 5000 and ROWNUM < 6000 then the error appears....
Here's the query:

                                inner join parts_master pnm on stm.pnm_auto_key = pnm.pnm_auto_key where SAJ.CHANGE_DATE < MONTHS.DT AND STM.PNM_AUTO_KEY = PNM.PNM_AUTO_KEY group by pnm_auto_key),0) OUTGOING

FROM
CALCULATIONS;Edited by: user574699 on Nov 17, 2008 2:10 AM code formatting

I suppose (how can i be sure?) that the queries in question are:
NVL((select sum(stm.qty_rec) from stock stm WHERE STM.REC_DATE < MONTHS.DT AND STM.PNM_AUTO_KEY = PNM.PNM_AUTO_KEY GROUP BY pnm_auto_key),0) INCOMINGand
    NVL((select sum(saj.qty_adj) from stock_adjust saj
                                inner join stock stm on saj.stm_auto_key = stm.stm_auto_key
                                inner join parts_master pnm on stm.pnm_auto_key = pnm.pnm_auto_key where SAJ.CHANGE_DATE < MONTHS.DT AND STM.PNM_AUTO_KEY = PNM.PNM_AUTO_KEY group by pnm_auto_key),0) OUTGOINGBoth queries have an aggregate function based on the grouping on PNM_AUTO_KEY. Both WHERE clauses also include the = PNM_AUTO_KEY statement. So how can these return more than 1 row?
As I stated I cannot run the subqueries without the rest. The database contains over 200000 PNM_AUTO_KEYS, and I don't know which one is causing the problems....

.Mac doesn't host domain names. If you are talking about web sites, you can have as many sites as will fit in your storage space. You can also use url forwarding to point to as many sites as you want.
The right place to ask questions about .Mac and domains is probably:

How can i use Itunes to update more than one IPad with more than one owner

How can i use Itunes to update more than one IPad with more than one owner? I own an IPad and my wife owns an IPad. I want to use my system to update both IPads. We have different Apple Accounts and different applications. Is this possible?

Of course, that is too easy. I am such a bonehead.

How can I change all of (or more than one) speaker note to a voice at once?

Hello...
I have a lot of speaker notes that I need to apply a specific voice to. How do I apply the same voice to all of the speaker notes in the whole project at once? Or at least more than one? Any help would be appreciated. Thank you! I am working with Captivate 6.

Hi Vikram,
Thanks. That tip definitely helps! You just have to be careful when you use the CNTRL button and not highlight the name of the slide as you try to highlight the voices. If you do that, then the drop down box becomes “unclickable”. Unfortunately, when using the control button, it is sometimes impossible not to highlight the name of the slide as well.

How can I enter my podcast in more than one category? Mine covers arts, education and society and culture, but is listed as "Performing Arts". Thank you for your time!

How can I enter my podcast in more than one category, to reflect the fact that it covers arts, education and society and culture? Thank you for your time!

You can have more than one category - this page shows you how the tags are formed:
http://www.apple.com/itunes/podcasts/specs.html#category
The Store will list only the first category and its sub-category at the top of the page. Like the first category, the others will in theory make your podcast available for searching by category. However searching just on the category in the iTunes Store is most unlikely to throw up your podcast. There are thousands of podcasts out there, and it would be quite impossible to display on one page the entire list for any category. What you see are 'featured' podcasts, chosen by Apple as being special; please see this Tech Note:
http://www.apple.com/itunes/podcasts/specs.html#getfeatured
Note that there is no way you can influence the selection other than making your podcast really special.
If you have further questions about making your podcast it's better to ask them in the Producing Podcasts forum.

Can I load my Itune on more than one computer?

Can I have ITunes installed on more than one computer, and sync with I-Phone and IPAD2? How do I keep the files the same on both computers?

you can authorize up to five computers you control for your iTunes store account.
you can use home sharing to keep the libraries on them in sync.
by design, iPhone and iPad can sync with only one library at a time.
however, you could consider Managing content manually on iPhone, iPad, and iPod.
