What Is Oracle 12C

Hi All ,
I Heard about the oracle 12C but i want more details about this new version of oracle poroducts .
if any one has any informations about this topic please tell me .
Best Regards ,

10g or 11g is not a product, it is a marketing label. There is database 11g, forms 11g, discoverer 11g,.......
If 12c is the new marketing label for oracle products asking "I want informations about 12c" is like asking "I want informations about the features of car".
As for when forms or database 12 (whatever letter it has) is released and what features will be included: typically oracle does not provide exact dates about when brandnew versions of their products are released, and what exact features they will include for sure. But basing the fact that the latest 11g versions of forms and the database have been released recently this might take some time.
cheers

What are the Oracle Home and GRID home directory locations for Oracle 12c (12.1.0.5) release

Hello All,
I plan to install and configure Oracle 12c Cloud Control console on a single standalone server and the version is Oracle 12.1.0.5. All the databases which are installed across in the entire farm/landscape are these versions:
Oracle 10.2.0.3 Enterprise Edition
Oracle 10.2.0.4 Enterprise Edition
Oracle 10.2.0.4 Active DataGuard Enterprise Edition
Oracle 10.2.0.5 Enterprise Edition
Oracle 11.2.0.1 Enterprise Edition
Oracle 11.2.0.1 Active DataGuard Enterprise Edition
Oracle 11.2.0.3 RAC Enterprise Edition
All Oracle databases across these versions will use the same version of Oracle Grid since ASM is used for all the Oracle database across Production/Test/Development databases. The OS is RHEL 5.8, RHEL 6.3, OEL 6.3 versions.
When installing the Oracle 12c Cloud Control what is the Oracle and Grid Home directory location need to set to. Please let me know if there are any other additional configurations needed?
Looking forward to hearing from you soon.
Regards,
Abhijit

First off, the only EM CC release out right now is 12.1.0.2, not sure where you got 12.1.0.5 (DB Plugin maybe?).
Second, you're confusing EM CC homes with DB/Grid homes.
EM CC will need it's own Oracle Home (i.e. /opt/oracle/product/em_12.1.0.2). You will need to provide repository database connection information, but EM does not care what home the db or grid is installed in.
I would recommend reviewing the documentation as well as the references on OTN -

What is the best source to learn and advice to get Oracle 12c (OCA) certificate???

Hi there,
I hope all are running good.
Actually, I'm a new in a Oracle career but I know all concepts of Databases and SQL.
I'm planning to take a Oracle 12c (1Z0-061) (SQL Fundamentals) exam to achieve 12c OCA certificate but I'm bit confused in what source is best to learn it by self and what are tips to pass those all exam to lead me OCA certificate. Please, kindly provide your valuable opinions. Look forward to hearing your replies.
Thanks

The Oracle Press exam guide for 1Z0-061 is written, though of course there is all sorts of production stuff still to go. The 1Z0-062 guide (a lot longer!) is done except for the last two chapters. So both should be out in the near future. I know this because my buddy Roopesh is writing 1Z0-061, and I'm writing 1Z0-062. Bob Bryla's 1Z0-063 guide is bit later, the exam isn't in beta yet.
As Philippe says, the OCA is not simple this time. Of course I can't reveal the exam content, but I think I can say that Oracle Uni is raising the standard with 12c .

What features says Oracle 12c, a cloud database?

Hi all,
I'm new cloud computing world and would like to what features bring 12c as a cloud ready database? Is it multitenant and/or are there any more things considering?
thanks
Pradeepa

There are many more features that were put in the 12c release specifically to make it a first class citizen for cloud deployments. Please take a look at the following links:
- Oracle White Paper:
http://www.oracle.com/technetwork/database/plug-into-cloud-wp-12c-1896100.pdf

What is the Oracle 12c Forms & Reports relase? what are the key benefits of Product?

Hi All,
Actually I heard from Oracle learning streams . Oracle 12c forms builder planned to release. what are the key features of release . when it is available in OTN ?
I have the following questions : ( Any one can answer me )
1. In Forms Builder PL/SQL Editor why don't we implement the CODE / syntax checker?
2. Is it possible to have the PL/SQL in built features automatically popup as soon as input the command by user ?
3. Is it possible to implement the Forms product without web browser help , I mean independent controller contacts through back end web logic server ?
4. Is It Possible to have more user friendly forms product, I mean fields editing at run time? or more features?
5. Will be getting the Migration assistance tool for 11g r2 to Oracle 12c ?
Many thanks in advance, will appreciate your highly attention on the same .
Thanking you & Best Regards

What are the sample schemas(like scott,hr) in oracle 12c?

Hi,
I have just downloaded and installed the oracle 12c on my desktop(Hurray!), but i don't see any of the sample schemas like scott and hr to play with. Do we have anything like those schemas in 12c?
Thanks,
sg

I have just downloaded and installed the oracle 12c on my desktop(Hurray!), but i don't see any of the sample schemas like scott and hr to play with. Do we have anything like those schemas in 12c?
Yes - but they would be in a PDB if you installed the sample schemas; you won't find them in the CDB.
If, like many people new to 12c, you did a default install for a database named ORCL and then connect to ORCL you are connecting to the CDB; that is, the root container. You won't find any sample schema there.
If you installed the sample schemas then the install process would have created one PDB name PDBORCL (by default) and that PDB would contain the sample schemas.
Then the next thing users typically do is connect as sysdba and do a STARTUP and then find they can't connect to PDBORCL. Surprise! The PDBs are NOT opened by default; you need to open them manually when you startup the DB or create an AFTER STARTUP trigger that opens the ones you want.

What are MD_ tables in Oracle 12c database? What is their purpose?

I just set up an Oracle 12c database with the purpose of migrating an existing Oracle 11.2.0.2 database. Our application developers are a bit confused when it comes to the schemas suddenly having MD_ tables they did not create. Any help is appreciated.

Did you do this using sql developer and the migration workbench to create a repository?
See if anything in this article rings a bell:
http://oraexplorer.com/2008/06/oracle-sql-developer-migration-workbench/#sthash.gNFtpafS.dpbs
Next, you will need to create a repository. An database account, which has CREATE SESSION, RESOURCE, and CREATE VIEW must be created first. Then logon into SQL Developer as that account. From the tool, create a repository from Migration menu > Repository Management > Create Repository. This process creates a bunch of MD* and MIGR* tables and packages.
I ask because you said you 'set up an Oracle 12c database' but then implied your developers are accessing it.
Most people experimenting with 12c create a multitenant database which has a CDB and one PDB that contains the sample schemas.
You typically would NOT allow developers access to the CDB; that is for admin purposes only. So, hopefully, if you developers access anything it is ONLY the sample PDB or a PDB that you have created from the seed.
Make sure you, and your developers RTFM about the new multitenant architecture or you will all get horribly confused when you try to do simple things like create users or issue grants. All of that works VERY differently in 12c.
See chapters 17 and 18 of the Database Concepts doc
http://docs.oracle.com/cd/E16655_01/server.121/e17633/cdbovrvw.htm
Pay particular attention to the discussion of 'common' and 'local' users. And a hidden 'gotcha' is that the PDBs will NOT be started/opened by default when you do a 'startup' of the database. If you create common users those users will NOT be created in PDBs that are not open; so there is the potential to have to do perform a lot of manual maintenance if you need to add those users to PDBs that weren't open at the time you added the users.

Pre-loading Oracle text in memory with Oracle 12c

There is a white paper from Roger Ford that explains how to load the Oracle index in memory : http://www.oracle.com/technetwork/database/enterprise-edition/mem-load-082296.html
In our application, Oracle 12c, we are indexing a big XML field (which is stored as XMLType with storage secure file) with the PATH_SECTION_GROUP. If I don't load the I table (DR$..$I) into memory using the technique explained in the white paper then I cannot have decent performance (and especially not predictable performance, it looks like if the blocks from the TOKEN_INFO columns are not memory then performance can fall sharply)
But after migrating to oracle 12c, I got a different problem, which I can reproduce: when I create the index it is relatively small (as seen with ctx_report.index_size) and by applying the technique from the whitepaper, I can pin the DR$ I table into memory. But as soon as I do a ctx_ddl.optimize_index('Index','REBUILD') the size becomes much bigger and I can't pin the index in memory. Not sure if it is bug or not.
What I found as work-around is to build the index with the following storage options:
ctx_ddl.create_preference('TEST_STO','BASIC_STORAGE');
ctx_ddl.set_attribute ('TEST_STO', 'BIG_IO', 'YES' );
ctx_ddl.set_attribute ('TEST_STO', 'SEPARATE_OFFSETS', 'NO' );
so that the token_info column will be stored in a secure file. Then I can change the storage of that column to put it in the keep buffer cache, and write a procedure to read the LOB so that it will be loaded in the keep cache. The size of the LOB column is more or less the same as when creating the index without the BIG_IO option but it remains constant even after a ctx_dll.optimize_index. The procedure to read the LOB and to load it into the cache is very similar to the loaddollarR procedure from the white paper.
Because of the SDATA section, there is a new DR table (S table) and an IOT on top of it. This is not documented in the white paper (the white paper was written for Oracle 10g). In my case this DR$ S table is much used, and the IOT also, but putting it in the keep cache is not as important as the token_info column of the DR I table. A final note: doing SEPARATE_OFFSETS = 'YES' was very bad in my case, the combined size of the two columns is much bigger than having only the TOKEN_INFO column and both columns are read.
Here is an example on how to reproduce the problem with the size increasing when doing ctx_optimize
1. create the table
drop table test;
CREATE TABLE test
(ID NUMBER(9,0) NOT NULL ENABLE,
XML_DATA XMLTYPE
XMLTYPE COLUMN XML_DATA STORE AS SECUREFILE BINARY XML (tablespace users disable storage in row);
2. insert a few records
insert into test values(1,'<Book><TITLE>Tale of Two Cities</TITLE>It was the best of times.<Author NAME="Charles Dickens"> Born in England in the town, Stratford_Upon_Avon </Author></Book>');
insert into test values(2,'<BOOK><TITLE>The House of Mirth</TITLE>Written in 1905<Author NAME="Edith Wharton"> Wharton was born to George Frederic Jones and Lucretia Stevens Rhinelander in New York City.</Author></BOOK>');
insert into test values(3,'<BOOK><TITLE>Age of innocence</TITLE>She got a prize for it.<Author NAME="Edith Wharton"> Wharton was born to George Frederic Jones and Lucretia Stevens Rhinelander in New York City.</Author></BOOK>');
3. create the text index
drop index i_test;
exec ctx_ddl.create_section_group('TEST_SGP','PATH_SECTION_GROUP');
begin
CTX_DDL.ADD_SDATA_SECTION(group_name => 'TEST_SGP',
                            section_name => 'SData_02',
                            tag => 'SData_02',
                            datatype => 'varchar2');
end;
exec ctx_ddl.create_preference('TEST_STO','BASIC_STORAGE');
exec ctx_ddl.set_attribute('TEST_STO','I_TABLE_CLAUSE','tablespace USERS storage (initial 64K)');
exec ctx_ddl.set_attribute('TEST_STO','I_INDEX_CLAUSE','tablespace USERS storage (initial 64K) compress 2');
exec ctx_ddl.set_attribute ('TEST_STO', 'BIG_IO', 'NO' );
exec ctx_ddl.set_attribute ('TEST_STO', 'SEPARATE_OFFSETS', 'NO' );
create index I_TEST
on TEST (XML_DATA)
indextype is ctxsys.context
parameters('
    section group   "TEST_SGP"
    storage         "TEST_STO"
') parallel 2;
4. check the index size
select ctx_report.index_size('I_TEST') from dual;
it says :
TOTALS FOR INDEX TEST.I_TEST
TOTAL BLOCKS ALLOCATED:                                                104
TOTAL BLOCKS USED:                                                      72
TOTAL BYTES ALLOCATED:                                 851,968 (832.00 KB)
TOTAL BYTES USED:                                      589,824 (576.00 KB)
4. optimize the index
exec ctx_ddl.optimize_index('I_TEST','REBUILD');
and now recompute the size, it says
TOTALS FOR INDEX TEST.I_TEST
TOTAL BLOCKS ALLOCATED:                                               1112
TOTAL BLOCKS USED:                                                    1080
TOTAL BYTES ALLOCATED:                                 9,109,504 (8.69 MB)
TOTAL BYTES USED:                                      8,847,360 (8.44 MB)
which shows that it went from 576KB to 8.44MB. With a big index the difference is not so big, but still from 14G to 19G.
5. Workaround: use the BIG_IO option, so that the token_info column of the DR$ I table will be stored in a secure file and the size will stay relatively small. Then you can load this column in the cache using a procedure similar to
alter table DR$I_TEST$I storage (buffer_pool keep);
alter table dr$i_test$i modify lob(token_info) (cache storage (buffer_pool keep));
rem: now we must read the lob so that it will be loaded in the keep buffer pool, use the prccedure below
create or replace procedure loadTokenInfo is
type c_type is ref cursor;
c2 c_type;
s varchar2(2000);
b blob;
buff varchar2(100);
siz number;
off number;
cntr number;
begin
    s := 'select token_info from DR$i_test$I';
    open c2 for s;
    loop
       fetch c2 into b;
       exit when c2%notfound;
       siz := 10;
       off := 1;
       cntr := 0;
       if dbms_lob.getlength(b) > 0 then
         begin
           loop
             dbms_lob.read(b, siz, off, buff);
             cntr := cntr + 1;
             off := off + 4096;
           end loop;
         exception when no_data_found then
           if cntr > 0 then
             dbms_output.put_line('4K chunks fetched: '||cntr);
           end if;
         end;
       end if;
    end loop;
end;
Rgds, Pierre

I have been working a lot on that issue recently, I can give some more info.
First I totally agree with you, I don't like to use the keep_pool and I would love to avoid it. On the other hand, we have a specific use case : 90% of the activity in the DB is done by queuing and dbms_scheduler jobs where response time does not matter. All those processes are probably filling the buffer cache. We have a customer facing application that uses the text index to search the database : performance is critical for them.
What kind of performance do you have with your application ?
In my case, I have learned the hard way that having the index in memory (the DR$I table in fact) is the key : if it is not, then performance is poor. I find it reasonable to pin the DR$I table in memory and if you look at competitors this is what they do. With MongoDB they explicitly says that the index must be in memory. With elasticsearch, they use JVM's that are also in memory. And effectively, if you look at the awr report, you will see that Oracle is continuously accessing the DR$I table, there is a SQL similar to
SELECT /*+ DYNAMIC_SAMPLING(0) INDEX(i) */
TOKEN_FIRST, TOKEN_LAST, TOKEN_COUNT, ROWID
FROM DR$idxname$I
WHERE TOKEN_TEXT = :word AND TOKEN_TYPE = :wtype
ORDER BY TOKEN_TEXT, TOKEN_TYPE, TOKEN_FIRST
which is continuously done.
I think that the algorithm used by Oracle to keep blocks in cache is too complex. A just realized that in 12.1.0.2 (was released last week) there is finally a "killer" functionality, the in-memory parameters, with which you can pin tables or columns in memory with compression, etc. this looks ideal for the text index, I hope that R. Ford will finally update his white paper :-)
But my other problem was that the optimize_index in REBUILD mode caused the DR$I table to double in size : it seems crazy that this was closed as not a bug but it was and I can't do anything about it. It is a bug in my opinion, because the create index command and "alter index rebuild" command both result in a much smaller index, so why would the guys that developped the optimize function (is it another team, using another algorithm ?) make the index two times bigger ?
And for that the track I have been following is to put the index in a 16K tablespace : in this case the space used by the index remains more or less flat (increases but much more reasonably). The difficulty here is to pin the index in memory because the trick of R. Ford was not working anymore.
What worked:
first set the keep_pool to zero and set the db_16k_cache_size to instead. Then change the storage preference to make sure that everything you want to cache (mostly the DR$I) table come in the tablespace with the non-standard block size of 16k.
Then comes the tricky part : the pre-loading of the data in the buffer cache. The problem is that with Oracle 12c, Oracle will use direct_path_read for FTS which basically means that it bypasses the cache and read directory from file to the PGA !!! There is an event to avoid that, I was lucky to find it on a blog (I can't remember which, sorry for the credit).
I ended-up doing that. the events to 10949 is to avoid the direct path reads issue.
alter session set events '10949 trace name context forever, level 1';
alter table DR#idxname0001$I cache;
alter table DR#idxname0002$I cache;
alter table DR#idxname0003$I cache;
SELECT /*+ FULL(ITAB) CACHE(ITAB) */ SUM(TOKEN_COUNT), SUM(LENGTH(TOKEN_INFO)) FROM DR#idxname0001$I;
SELECT /*+ FULL(ITAB) CACHE(ITAB) */ SUM(TOKEN_COUNT), SUM(LENGTH(TOKEN_INFO)) FROM DR#idxname0002$I;
SELECT /*+ FULL(ITAB) CACHE(ITAB) */ SUM(TOKEN_COUNT), SUM(LENGTH(TOKEN_INFO)) FROM DR#idxname0003$I;
SELECT /*+ INDEX(ITAB) CACHE(ITAB) */ SUM(LENGTH(TOKEN_TEXT)) FROM DR#idxname0001$I ITAB;
SELECT /*+ INDEX(ITAB) CACHE(ITAB) */ SUM(LENGTH(TOKEN_TEXT)) FROM DR#idxname0002$I ITAB;
SELECT /*+ INDEX(ITAB) CACHE(ITAB) */ SUM(LENGTH(TOKEN_TEXT)) FROM DR#idxname0003$I ITAB;
It worked. With a big relief I expected to take some time out, but there was a last surprise. The command
exec ctx_ddl.optimize_index(idx_name=>'idxname',part_name=>'partname',optlevel=>'REBUILD');
gqve the following
ERROR at line 1:
ORA-20000: Oracle Text error:
DRG-50857: oracle error in drftoptrebxch
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CTX_DDL", line 1141
ORA-06512: at line 1
Which is very much exactly described in a metalink note 1645634.1 but in the case of a non-partitioned index. The work-around given seemed very logical but it did not work in the case of a partitioned index. After experimenting, I found out that the bug occurs when the partitioned index is created with dbms_pclxutil.build_part_index procedure (this enables enables intra-partition parallelism in the index creation process). This is a very annoying and stupid bug, maybe there is a work-around, but did not find it on metalink
Other points of attention with the text index creation (stuff that surprised me at first !) ;
- if you use the dbms_pclxutil package, then the ctx_output logging does not work, because the index is created immediately and then populated in the background via dbms_jobs.
- this in combination with the fact that if you are on a RAC, you won't see any activity on the box can be very frightening : this is because oracle can choose to start the workers on the other node.
I understand much better how the text indexing works, I think it is a great technology which can scale via partitioning. But like always the design of the application is crucial, most of our problems come from the fact that we did not choose the right sectioning (we choosed PATH_SECTION_GROUP while XML_SECTION_GROUP is so much better IMO). Maybe later I can convince the dev to change the sectionining, especially because SDATA and MDATA section are not supported with PATCH_SECTION_GROUP (although it seems to work, even though we had one occurence of a bad result linked to the existence of SDATA in the index definition). Also the whole problematic of mixed structured/unstructured searches is completly tackled if one use XML_SECTION_GROUP with MDATA/SDATA (but of course the app was written for Oracle 10...)

I understand this is an unsupported OS, however was checking if anyone had encountered a similar issue and went through with it.
Just dont want to switch this OS which iam using it for a while to get through. Considerably, I have the option of having this on oracle virtual machine to set it up allowing my OS to eat up a good amount of resources
Thanks

How much real memory does your ubuntu machine have?
How much memory do you really need to allocate to the virtual machine?
Really?
What "resources" do you expect to be eaten up by running a single vm guest on an Ubuntu host?
I run a full suite of vm's on my Win7 Pro host. I size the vm's at 2gb each and, with 8gb of real memory on the silicone, can have 3 of them up at once. Ubuntu shouldn't be near the hog of ram or cpu that Windows is.

Not Able to Create database objects(Tables, etc) in Oracle 12c

Hello Sir,
Recently, I have installed oracle 12c in my PC. And I am able to connect with the ANONYMOUS user and connection name ORCL.
But I am not able to create any objects in database like tables creation, it's just showing the error message like- you don't have sufficient privileges.
Could you please help on this? How to start the work on oracle 12c database as I have worked on Oracle 11g with the SCOTT user and connection name ORCL.It was working fine. But SCOTT user is not present in 12c. Is there any other USER in 12c with the default tables like EMP table in 11g in the SCOTT USER schema?
Please suggest, what to do?
Thanks In Advance!!

Hi Nishant ,
Thanks for the reply.
    I have done all the steps as you mentioned above. I am not able to create HR user. Please check the below errors and
please guide me on this.

Informatica 9.1 with oracle 12c. Not able to connect to the PDB while instalation

Dear Peers,
I installed oracle 12c on my laptop. And by default PDB created, TNS entries added for the same and successfully connected to PDB. In my PDB i created two users and I am able to connect with them also.
While installing the informatica server with 64 bit, in the part of domain configuration repository I am not able to connect to my users those I created. I am not able to connect to either CDB or PDB also. I am not able to get the what is the error is. But in oracle I am able to connect to my PDB with those users.
Any one overcome on this issues, Please help me.
Thanks

If you can connect using sql*plus from the same machine you are using informatica to connect from then you have an informatica issue and should try posting in an informatica forum.

POWERBUILDER 12.5 and ORACLE 12C DBNAME

Dear all,
As mentioned on other threads, PB 12.5.2 works with ORACLE 12C, but not officially supported.
ORACLE 12C works with PB 12.6
Nevertheless, when I do try to work with ORACLE 12C and PB 12.5.2, when I created datawindow, on the Column specification tab, on the DB Name column, I have only the column name (column_name), while when working with ORACLE 11, I get table_name.column_name
Is there a way to overcome it?
Thanks

Did you get any further? I looked through my old PB installations and did a quick test using an ODBC connection to an ASA DB.
Open the database painter, then from the main menu, click Design -> Options and see what you have for "Use Extended Attributes".
Disconnecting from my DBs, enabling this option, exiting/restarting PB and reconnecting created the PB Catalog tables.
I then disconnected from all my DBs, disabled the option, exited PB. Opened an interactive SQL session and dropped all 5 of the PB catalog tables. After restarting PB, the catalog tables were not created.
So, "Use Extended Attributes" is how to enable/disable the PB catalog tables.

IZ0-047 and Oracle '12c'

Hello,
According to this article http://www.computerworlduk.com/news/applications/3361449/oracle-12c-database-set-for-december-or-january-release/
The new version of Oracle '12c' is scheduled to be released on December this year or January 2013...
I just wanna know if the IZ0-047 : SQL Expert will still be valid for the new version of Oracle?
your thoughts?
Thanks

I just wanna know if the IZ0-047 : SQL Expert will still be valid for the new version of Oracle?It depends on what you mean by 'valid'. If you are asking whether people certified as SQL Experts will continue to have a valid certification, I guarantee that will be the case. Oracle does not invalidate existing certifications when new releases come out. The SQL Expert certification, like the PL/SQL developer certifications (and unlike the DBA certifications) is not 'versioned'. Someone getting this certification today does not become an "Oracle 11g SQL Expert".
If you are asking whether the content of the SQL Expert test will still be valid for Oracle 12c, the question becomes (slightly) grayer. I have not been following Oracle 12c. I know that it's supposed to be cloudier, but little else about it. It may well contain significant new SQL functionality that should be included in the SQL Expert exam. However, I'm certain that it will not invalidate the information that exists in the current test. Oracle will not abandon ANSI SQL or remove existing functionality. Even if new functionality exists and Oracle decides to add it to a new version of the Expert test, this is unlikely to happen for quite some time following the release and would probably require a new beta exam. In all, a new 12c-enhanced test (if such were even to happen) wouldn't be available until 2014.
I can't see worrying too much about it myself. If you're interested in obtaining this certification, then I would go for the current version rather than waiting on some future update that may not happen for years.

Oracle 12c 32 bit Client failure

All,
I am trying to install the Oracle 12c 32 bit on Windows XP and it fails. It does the initial check and then fails. It posts the following error to the temporary installation directory. I have no clue what is trying to tell me.

Oracle 12c workspace creation

Hi all!
How can I create APEX workspace referencing to local user (Oracle 12c)? APEX_040200, ANONYMOUS, XDB, APEX_PUBLIC_USER is comon users by default, but HR and so on are local. What should i do?

Hi Andrey,
To assist in resolving your issue, could you please provide some additional information in relation to your installation. As part of your 12c configuration, and with APEX 4.2 installed in your container database, how have you configured your new pluggable database (PDB) i.e. using EPG or APEX Listener or Oracle HTTP Server, as outlined in the 4.2. Installation Guide for 12c? The reason I ask is because, if you're using EPG, for example, each PDB will have a distinct port number and you'd need to ensure that the URL you're using to access the APEX Administration Services is the correct one.
My colleague, Jason Straub, has posted a number of blog postings relating to APEX and 12c, as well as a link to a chapter in the Installation Guide for 4.2 with 12c, which you might find helpful.
Regards,
Hilary
