If you don't know what a CON_ID is or what CDB_USERS contains then you need to start by following that infamous advice: RTFM!
Seriously, many developers will NOT be successful and will have MANY issues similar to yours if they do not firt read the docs and learn about the new multitenant architecture that 12c introduces.
IMHO it is simply a MUST that people learn the basics of the new architecture of 12c or they will have problems/issues doing even simple things like: connecting to the proper database, starting up PDBs, creating users (common vs. local) and using the large set of new CDB_* views.
See my replies in these two threads for a larger discussion and more links to the doc sections to review:
https://forums.oracle.com/thread/2554568
https://forums.oracle.com/thread/2559874
In that second link I show you the queries you can execute to determine what containers you have and what service names map to those containers.
I also show why you need to answer a whole slew of questions and provide much more information to the forum when you ask questions re 12c:
1. Did you create:
A. A non-CDB PDB named ORCL
B. A CDB named ORCL with no PDBs
C. A CDB named ORCL with a PDB that you think is named ORCL but is really named PDBORCL
2. Is your CDB up and running?
3. Have your PDBs been opened?
4. Are you are trying to connect to CDB or PDB?
If you do a basic install and create a sample database (that would include the SCOTT schema) you will get:
1. A CDB named ORCL - this is the CDB$ROOT and will NOT have SCOTT since it is NOT the sample database
2. PDB$SEED - the 'seed' DB that will be used as a template when you create new PDBs
3. PDBORCL - this is the sample DB and has the SCOTT schema
So you are likely connecting to ORCL (the CDB) and that doesn't have a SCOTT schema as your exception indicates. You need to connect to PDBORCL and you can only do that after you open it.
One way to open your PDBs is to issue:
>
ALTER PLUGGABLE DATABASE ALL OPEN;
>
after you connect as SYS to the CDB. Then you need to open a connection to service name PDBORCL.
Please read the referenced threads above and the doc section on the multi-tenant architecture.
RTFM is going to be a very common response to anyone posting 12c questions if their question shows, as yours does, that the poster likely hasn't read the basic sections. There is simply too much new architecture to try to explain it in the forums.

Hi guys,
I am new at oracle and I just installed the Oracle 10g express. after login to the oracle by SQL Developer I noticed there are lots of tables in table folder which some of them come with $ and some not! can you please let me know what are these tables for? are they like system tables in SQL Server? if so then what are the tables under

Hi user;
what are the common error while EBS R12 installation with os unix and windows.AFAIK there is no document which show common error.There are some common error for installation like:
RW-5004- RW-50010 etc.
For error we have to check instalaltion log files for can get more details about it
oracle have any any check after installation all installation are correct according to no of directory, files and file size ?Oracle has 2 checking mechanisim during installation.
1. Before start installation, rapidwiz makes Validate system Configuration check which is checking port avaliability,file system check etc.
2. End of the installation,rapidwiz makes Validate system Configuration again to check jsp,dbc file, db avaliablity etc..

What are the User Exits for Sales Order creation process?

Hi,
what are the User Exits for Sales Order creation process? how can I find them?
thanks in advance,
will reward,
Mindaugas

Please check this info:
User Exits In Sales Document Processing
This IMG step describes additional installation-specific processing in sales document processing. In particular, the required INCLUDES and user exits are described.
Involved program components
System modifications for sales document processing affect different areas. Depending on the modification, you make the changes in the program components provided:
MV45ATZZ
For entering metadata for sales document processing. User-specific metadata must start with "ZZ".
MV45AOZZ
For entering additional installation-specific modules for sales document processing which are called up by the screen and run under PBO (Process Before Output) prior to output of the screen. The modules must start with "ZZ".
MV45AIZZ
For entering additional installation-specific modules for sales document processing. These are called up by the screen and run under PAI (Process After Input) after data input (for example, data validation). The modules must start with "ZZ".
MV45AFZZ and MV45EFZ1
For entering installation-specific FORM routines and for using user exits, which may be required and can be used if necessary. These program components are called up by the modules in MV45AOZZ or MV45AIZZ.
User exits in the program MV45AFZZ
The user exits which you can use for modifications in sales document processing are listed below.
USEREXIT_DELETE_DOCUMENT
This user exit can be used for deleting data which was stored in a separate table during sales document creation, for example, if the sales document is deleted.
For example, if an additional table is filled with the name of the person in charge (ERNAM) during order entry, this data can also be deleted after the sales order has been deleted.
The user exit is called up at the end of the FORM routine BELEG_LOESCHEN shortly before the routine BELEG_SICHERN.
USEREXIT_FIELD_MODIFICATION
This user exit can be used to modify the attributes of the screen fields.
To do this, the screen fields are allocated to so-called modification groups 1 - 4 and can be edited together during a modification in ABAP. If a field has no field name, it cannot be allocated to a group.
The usage of the field groups (modification group 1-4) is as follows:
Modification group 1: Automatic modification with transaction MFAW
Modification group 2: It contains 'LOO' for step loop fields
Modification group 3: For modifications which depend on check tables or on other fixed information
Modification group 4: is not used
The FORM routine is called up for every field of a screen. If you require changes to be made, you must make them in this user exit.
This FORM routine is called up by the module FELDAUSWAHL.
See the Screen Painter manual for further information on structuring the interface.
USEREXIT_MOVE_FIELD_TO_VBAK
Use this user exit to assign values to new fields at sales document header level. It is described in the section "Transfer of the customer master fields into the sales document".
The user exit is called up at the end of the FORM routine VBAK_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBAP
Use this user exit to assign values to new fields at sales document item level. It is described in the section "Copy customer master fields into the sales document".
The user exit is called up at the end of the FORM routine VBAP_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBEP
Use this user exit to assign values to new fields at the level of the sales document schedule lines.
The user exit is called up at the end of the FORM routine VBEP_FUELLEN.
USEREXIT_MOVE_FIELD_TO_VBKD
Use this user exit to assign values to new fields for business data of the sales document. It is described in the section "Copy customer master fields into sales document".
The user exit is called up at the end of the FORM routine VBKD_FUELLEN.
USEREXIT_NUMBER_RANGE
Use this user exit to define the number ranges for internal document number assignment depending on the required fields. For example, if you want to define the number range depending on the sales organization (VKORG) or on the selling company (VKBUR), use this user exit.
The user exit is called up in the FORM routine BELEG_SICHERN.
USEREXIT_PRICING_PREPARE_TKOMK
Use this user exit if you want to include and assign a value to an additional header field in the communication structure KOMK taken as a basis for pricing.
USEREXIT_PRICING_PREPARE_TKOMP
Use this user exit if you want to include or assign a value to an additional item field in the communication structure KOMP taken as a basis for pricing.
USEREXIT_READ_DOCUMENT
You use this user exit if further additional tables are to be read when importing TA01 or TA02.
The user exit is called up at the end of the FORM routine BELEG_LESEN.
USEREXIT_SAVE_DOCUMENT
Use this user exit to fill user-specific statistics update tables.
The user exit is called up by the FORM routine BELEG-SICHERN before the COMMIT command.
Note
If a standard field is changed, the field r185d-dataloss is set to X. The system queries this indicator at the beginning of the safety routine. This is why this indicator must also be set during the maintenance of user-specific tables that are also to be saved.
USEREXIT_SAVE_DOCUMENT_PREPARE
Use this user exit to make certain changes or checks immediately before saving a document. It is the last possibility for changing or checking a document before posting.
The user exit is carried out at the beginning of the FORM routine BELEG_SICHERN.
User exits in the program MV45AFZA
USEREXIT_MOVE_FIELD_TO_KOMKD
Use this user exit to include or assign values to additional header fields in the communication structure KOMKD taken as a basis for the material determination. This is described in detail in the section "New fields for material determination".
USEREXIT_MOVE_FIELD_TO_KOMPD
Use this user exit to include or assign values to additional item fields in the communication structure KOMPD taken as a basis for the material determination. This is described in detail in the section "New fields for material determination".
USEREXIT_MOVE_FIELD_TO_KOMKG
Use this user exit to include or assign values to additional fields in the communication structure KOMKG taken as a basis for material determination and material listing. This is described in detail in the section "New fields for listing/exclusion".
USEREXIT_MOVE_FIELD_TO_KOMPG
Use this user exit to include or assign values to additional fields in the communication structure KOMPG taken as a basis for material determination and material listung. This is described in detail in the section "New fields for listing/exclusion".
USEREXIT_REFRESH_DOCUMENT
With this user exit, you can reset certain customer-specific fields as soon as processing of a sales document is finished and before the following document is edited.
For example, if the credit limit of the sold-to party is read during document processing, in each case it must be reset again before processing the next document so that the credit limit is not used for the sold-to party of the following document.
The user exit is executed when a document is saved if you leave the processing of a document with F3 or F15.
The user exit is called up at the end of the FORM routine BELEG_INITIALISIEREN.

What are the best practices to migrate VPN users for Inter forest mgration?

What are the best practices to migrate VPN users for Inter forest mgration?

It depends on a various factors. There is no "generic" solution or best practice recommendation. Which migration tool are you planning to use?
Quest (QMM) has a VPN migration solution/tool.
ADMT - you can develop your own service based solution if required. I believe it was mentioned in my blog post.

What are the minimum db user privileges required for CDC?

What are the minimum privileges required for the source data server user in order to to successfully implement CDC
Currently I'm getting an "Insufficient privileges" error when trying to start a CDC journal on a model. The error is happening on the step that creates a trigger on the table in the source schema.
Here's the situation:
The data server uses the user "ODI_TEMP" for its connection. ODI_TEMP has been granted select privileges on the desired tables in the source schema. When starting the CDC journal on the model for the source schema, ODI tries to create a trigger on the source tables. This fails since the ODI_TEMP user can't create triggers on anything outside of it's own schema. For obvious fundamental security reasons, we cannot give the ODI_TEMP user the CREATE ANY TRIGGER system privilege on the data source.
Journalizing is set up using JKM Oracle Consistent. ODI is 11g, DB is 11g.

Hi,
You can go for this
Grant CREATE ANY TRIGGER system privilege to ODI_TMP
Start the Journal , it will create triggers in ODI_TMP schema for the tables present in your source schema.
Now revoke CREATE ANY TRIGGER system privilege from ODI_TMP.
It will continue to work .. only when you are restarting the journal (due to adding or removing some tables in CDC) , you will be requiring CREATE ANY TRIGGER privilege.
Thanks,
Sutirtha

What are the best practices for the RCU's schemas

Hi,
I was wondering if there is some best practices about the RCU's schemas created with BIEE.
I already have discoverer (and application server), so I have a metadata repository for the Application Server. I will upgrade Discoverer 10g to 11, so I will create new schema with RCU in my metada repository (MR) of the Application Server. I'm wondering if I can put the BIEE's RCU schemas in the same database.
Basically,
1. is there a standard for the PREFIX ?
2. If I have multiple components of Fusion in the same Database, I will have multiples PREFIX_MDS schema ? Can they have the same PREFIX ? Or They all need to have a different prefix ?
For exemple: DISCO_MDS and BIEE_MDS or I can have DEV_MDS and this schema is valid for both Discoverer and BIEE.
Thank you !

Hello Prasad,
For ESS and MSS you do not require special data from the backend side, If a person has master data maintained in PA30, He can see his personal details in ESS, For that employee should maintain the Portal user id in Infotype 0105 , subtyp0001.
With that userid he can able to enter the portal and maintain his details. Same is the case for MSS , Manager should have maintained 0105 subtype 0001. and he can see the details of his employees in MSS application.
For ESS you need to have Portal
SAP_ESS
PCUI_GP
BP for ESS

Hi,
We have seen that. Thanks.
Now, how could we add multiple tiems to ATG's shopping cart before redirecting the user to ATG's home?
The scenario we see is:
User navigates on a Marketing website, spots items he/she is interested in and add them to the LOCAL shopping cart (without leaving the current website), after adding many items he/she decides to buy these items buy clicking FINISH, at this moment we add the N items to ATG shopping cart (how??) and redirect the user to ATG's home.
Is that possible?
Thanks

What are the best settings to use for the newest AirPort Extreme (AC wifi) with my optimum online service provider?

I have the current generation of the AirPort Extreme and a handful of devices that utilize the new 5Ghz A/C frequency. My internet speeds were blazing fast when I had first set it up but lately it has been lagging terribly. I was told that changing my dhcp did help, which it did it seems like it might be back to its normal speeds but I just want to know what are the best settings to configure for the airport so that I can get the most out of my service on all my devices? I'm using a CAT 6 cable which does help, I have a guest wifi setup with a wifi password which I understand will slow it down a little. Can anyone just point me in the right direction or just give me a step by step guide on what settings to configure? Should I really consider turning off the guest network?

I am assuming that you are looking to configure your network to provide the highest level of bandwidth possible for your network clients. If that is the case, the following are a few things to consider:
The Internet modem should support Gigabit Ethernet. That is the Ethernet connection between the modem and your 802.11ac AirPort Extreme should be Gigabit Ethernet.
Use CAT-5e or CAT-6 Ethernet cables between all wired connections.
Only expect 802.11ac performance with 802.11ac clients in the same room as the base station.
Eliminate or significantly reduce any forms of Wi-Fi interference on both the 2.4 & 5 GHz bands.
When streaming, especially HD video on your local network, use wired connections between the host and player devices when possible.
Other than the above suggestions there are no "magic" settings that you can make on your AirPort. Note: The Guest network shares the same bandwidth as the "main" network. Unless you have a network goal to provide this type of network, it is best left disabled.
