Jdeveloper JSP-Struts (which is the right way to decalre a DataSource)

Hello to all..
I'am developing web application for a car assicuration.
I would like to know which is the right "connection" (jndi name) to use in my application..
I have made a JDBC connection to my production databse...
Then I have made a Data Source from menu (Jdeveloper -> Tools -> Embeded Oc4J -> Current workspace -> Datasources...
Here I have created a new DataSource from "Autocreate from IDE..."...
My Question is.. which Class name I must use?
Default class is: com.evermind.sql.DriverManagerDataSource
I see that there is also a: oracle.jdbc.pool.OracleConnectionPoolDataSource..
Which Class I must select? My application is used by many users online..
Is there any axample on oracle to see how to use JNDI connections (connection pool)..
I'am using Jdeveloper version: 10.1.2.1.0
best regards
Peter

AFAIK all connections, DataSource ones included are created by calling the DriverManager. A DataSource is a factory for Connection objects (from JavaDocs)
If you're talking about managing connections then it depends on the application. A DataSource is great for apps that can support many clients or are multi-threaded, but may require a JNDI implementation to get to it.
If however you have an single threaded app that hits the database in a serial fashion, then DataSource is probably an overkill.

Which is the right way?/place to post the suggestion to SAP

Hi Freinds,
if someone have to make a suggestion to SAP, for its product extension..or maybe a new feature to add to its existing product offering...which is the right place...shld it be in the form of a blog or a post in a forum...
and if indeed turns out to be a unique feasible feature and gets lots of positive response...why kind of recognition will it get....

lol. there's a world outside the US for those who don't know.
therefore ASUG might not be the right address for someone living elswhere. there are some SAP user groups in other areas of this world, eg in germany it's DSAG; unfortunately you have to be a member of those 'societies' (membership fee) and it's not easy to make yourself heard in the beginning.
SAP could provide better channels for that, e.g. special SDN areas for that purpose.

What is the right way to re-format idop's Classic Hard Disk?

Since my ipod classic 160 GB is malfunctioning, after I did a lot of restores
trying to fix it without success,
I've done a HDSMARTDATA test with the following results:
Retracts: 2
Reallocs: 9880
Pending Sectors: 0
PowerOn Hours: 16
Start/Stops: 296
Temp: Current 25c
Temp: Min 19c
Temp: Max 56c
I can see that there are a lot of Reallocs .
a) Can anybody advice, if they are really a lot enough to cause problems, e.g. not playing songs, rebooting itself e.t.c.
b) I was thinking to reformat its HD. Can anybody tell me which is the RIGHT way to do that (steps)?
c) Will I be able to restore its firmware (via itunes) after the re-formating ?
The current firmware is 2.0.4.
I use Windows XP (SP3), and the latest revision of itunes (10.1.1.4).

Yes you can format ipod in windows just like you format any usb device, and then use restore in itunes. Check the link: http://www.methodshop.com/gadgets/ipodsupport/erase/index.shtml .

Which is the best way of deploying JSP (mod_ose or OSE) ?

I need to deploy some jsps that are using servlet api 2.2 and i would like to know which is the best way of deploying these jsps?
Thanks
RJC

Speaking of JServ Vs OSE, I have some related questions on it. I would appreciate if someone can answer:
1.For a stateful servlet (assuming that we are using Oracle JVM), Will it not call the init() method of the servlet each time for a client (because each client will have his own Oracle JVM)? If so, isn't that expensive because it needs to initialize the servlet again?
Again, for the same servlet, Will it not have a servlet context for each and every client? Isn't that expensive? ( A servlet context by definition maintains state information for all instances of a web application within any single JVM)
2. If we have an application that has some portion of it which is stateless and some portion of it which is stateful, how do we make a choice JDK JVM vs Oracle JVM?
Can we (for the same application) use both the JDK JVM as well as Oracle JVM? If so, how does the JDK JVM talk with Oracle JVM?
3. Since Oracle JVM is useful for stateful applications only, does it mean that we cannot use it for Stateless session beans? (In an application we might have stateless session beans, stateful session beans as well as entity beans) Should we be using JDK JVM or Oracle JVM?
4. For Servlets too, we might have stateless servlets and stateful servlets within the same application. If so, can we use JDK JVM for stateless servlets and Oracle JVM for stateful servlets? If so, how does the JDK JVM talk with Oracle JVM?

How to create a custom panel in the right way (without having an empty panel in the file info) ?

Hi Everyone
My name is Daté.
I'm working in the fashion industry as a designer and Design consultant to help fashion brands improving the design workflow by using Adobe softwares and especially Illustrator.
I'm not a developper, but i'm very interested about the possibility to introduce xmp technology to provide more DAM workflows in the fashion industry.
Fashion designers produce a lot of graphical objects in illustrator or Photoshop. Unfortunately they are faced to a big challenge which is about how to manage, search, classify and get this files faster. Of course PDM system or PLM system are used in the Fashion industry to manage data, but for many companies, implemanting this kind of database is very complex.
When i look at what you can do with xmp, it seems to be an interesting way of managing design files, then i started to follow Adobe instruction to try to build a custom panel.
The main idea is to (Theory) :
create custom panels used by fashion designers to classify their design files.
Use Adobe Bridge to search files, create smart collection to make basic reports in pdf and slideshows
Find someone to make a script able to export metadata in xml files
Use indesign and the xml file to generate automatically catalogues or technical sheets based on xmp values
I have created a custom panel by using the generic panel provided by Adobe and i have modified the fields to feet with the terms used in the fashion industry and it works well.
But unfortunately, when i try to create my own custom panel from scratch with Flashbuilder (4.6) and the Adobe CSExtensionBuilder_2 (Trial version), it doesn't work!
Here is the process :
I have installed flashbuilder 4.6
I have download the XMP Fileinfo SDK 5.1 and placed the com.adobe.xmp.sdk.fileinfo_fb4_1.1.0.jar in C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\eclipse\plugins
In Flashbuilder, i have created a new project and select xmp Custom panel
The new project is created in flashbuilder with a field with A BASIC Description Field
To generate the panel, right click the project folder and select xmp / Publish Custom Panel
The panel is automatically generated in the following folder : C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels
Go to illustrator, Open the file Info
The panel appears empty
The others panel are also empty
The panel is created and automatically placed in the right folder, but when you open it in Illustrator by selecting the File Info option in the File Menu, this custom panel appears empty!!! (only the title of the tab is displayed). This panel also prevent the other panels to be displayed.
When you delete this custom panels from the folder C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels and go back to the File Info, the other panels display their content properly.
I also try to use the plugin XMP Namespace designer to create my own namespace. this plugin is also able to generate a custom panel, but this one also appears empty in AI or Photoshop.
I try to follow the process described in Adobe xmp documentation many times, but it didn't works.
It seems that many peaople have this issue, but i dodn't find a solution in the forum.
I try to create a trust file (cfg), but it didn't work.
It would be so kind if you can help me to understand why i can't create a custom panel normally and how to do it in the right way.
Thanks a lot for your help,
Best regards,
Daté

Hi Sunil,
After many trial, i realize the problem was not coming from the trust file, but from the way i have created the custom panel.
There is 2 different ways, the first described below is not working whereas the second is fine :
METHOD 1 :
I have downloaded the XMP-Fileinfo-SDK-CS6
In the XMP-Fileinfo-SDK-CS6 folder, i copied the com.adobe.xmp.sdk.fileinfo_fb4x_1.2.0.jar plugin from the Tools folder and i pasted it in the plugind folder of Flashbuilder 4.6
The plugin install an XMP project
In Flashbuilder 4.6 i have created a new project (File / New /Project /XMP/XMP Custom Panel)
A new xmp project is created in flashbuilder.
You can publish this project by right clicking the root folder and selecting XMP / Publish Custom Panel
The custom file info panel is automatically published in the right location which is on Mac : /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/3.0 or /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/4.0
Despite the publication of the custom file info panel and the creation of a trust file in the following location : "/Library/Application Support/Macromedia/FlashPlayerTrust", the panel is blank in Illustrator.
I try this way several times, with no good results.
METHOD 2 :
I have installed Adobe CSExtensionBuilder 2.1 in Flash Builder
In FlashBuilder i have created a new project (File / New /Project /Adobe Creative Suite Extension Builder/XMP Fileinfo Panel Project)
As the system display a warning about the version of the sdk to use to create correctly a custom file info, I changed the sdk to sdk3.5A
The warning message is : "XMP FileInfo Panel Projects must be built with Flex 3.3, 3.4 or 3.5 SDK. Building with Flex 4.6.0 SDK may result in runtime errors"
When i publish this File info panel project (right click the root folder and select Run as / Adobe illustrator), the panel is published correctly.
The last step is to create the trust file to display the fields in the panel and everything is working fine in Illustrator.
The second method seems to be the right way.
For sure something is missing in the first method, and i don't understand the difference between the XMP Custom Panel Project and the XMP Fileinfo Panel Project. Maybe you can explain it to me.
So what is the best solution ? the right sdk to use acording to the creative suite (the system asks to use 3.3 or 3.5 sdk for custom panels, so why ?)
I'm agree with Pedro, a step by step tutorial about this will help a lot of peaople, because it's not so easy to understand!!!
Sunil, as you belong to the staff team, can you tell me if there is :
A plugin or a software capable to extract the XMP from llustrator files to generate XML workflows in Indesign to create catalogues
A plugin to allow indesign to get custom XMP in live caption
A plugin to allow Bridge to get custom XMP in the Outputmode to make pdf or web galeries from a smart collection
How can you print the XMP data with the thumbnail of the file ?
Thanks a lot for your reply.
Best Regards

What is the right way to move a directory to another drive?

When I move a directory to another location using drag and drop in the Elements 11 Organizer folder tree most, if not all, of the images become unlinked. What is the right way to move a directory and have the image paths updated in the Organizer database? Thanks.

That's something I just did successfully one hour ago...
I suppose your are in the 'folder' view with full folder tree, not in the 'My folder' view which only shows the lower subfolder level recorded in the database.
Do you try to move a folder with its subfolders ?

Using StAX with xslt transformations in the right way?

Hi!
What do I need to enable the stax functionality to transformations, and which transformer implementations is supporting this? (or is the implementation irrelevant)
I have made the following to create a StaxSource, but is it enought?
---8<---
private static XMLInputFactory inputFactory = XMLInputFactory.newInstance();
    InputStream xmlInputStream = xmlUrl.openStream();
    XMLStreamReader xmlStreamReader = inputFactory.createXMLStreamReader( xmlInputStream );
    Source xmlSource = new StAXSource( xmlStreamReader );
transformer.transform(xmlSource, new StreamResult(writer));
---8<---I'm using:
org.apache.xalan.processor.TransformerFactoryImpland every thing seems to work very nice, but I'm not sure if I have done it in the right way and if it's something that I miss.
If I understand it correct normal transformations is transforming the xml to a Dom-tree but with StAX it shouldn't and be more memory efficient.
So anyone have any comments?
/Per

Indeed, as DrClap has already stated, using a StAXSource will not guarantee streaming. All of the mainstream XSLT processors build some sort of DOM structure internally because, in the general case, XSLT requires random access on the input document. The only exception to this is the identity transform, which in most processors is done in streaming fashion --i.e., without actually creating an intermediate structure.

What is the right way to change the active JInternalFrame for and MDI app?

I am working on my own implementation of the window menu. The action that is triggered when a customer chooses a window to activate from the list in the menu is not behaving as I expected. The code I wrote (below) switches frames correctly but the caption bar never gets updated and if you restore a frame from an icon the frame is not correctly activated, there is even a restore button which if you push fixes things up and the frame then behaves normally     if (frameToActivate.isIcon ()) {
          // Restore from icon
          desktopPane().getDesktopManager().deiconifyFrame (frameToActivate);
     desktopPane().getDesktopManager().activateFrame (frameToActivate);
     desktopPane().setSelectedFrame (frameToActivate);I did a search of the web and found a tip on JavaWorld (http://www.javaworld.com/javaworld/jw-05-2001/jw-0525-mdi.html) which led me to try doing this from a different angle - the JInternalFrame's point of view. This code works     try {
          if (frameToActivate.isIcon ()) {
               // Restore from icon
               frameToActivate.setIcon (false);
          frameToActivate.moveToFront();
          frameToActivate.setSelected (true);
     } catch (PropertyVetoException error) {
          error.printStackTrace();
     }My question is why does the desktop based approach not work? If methods exist that appear to let you restore and switch between frames why are the ineffective? Am I missing something obvious that I should be doing?
If using the JInternalFrame methods is the right way to go then I will It just seems like if the DesktopManager has methods that advertise that is supports managing the active frame then they should work. Before I ignore them I want to check with you to see if there is a right way to use them.
Ian

So, this is another batch of duke dollars I cannot assign - since I solved my own problem:-)
I had an epiphany and tried setting break points to see what code was executed when you click on an inactive frame. From that I determined that DefaultDesktopManager.activateFrame, as implemented, does not activate the frame but acknowledges the activation of a frame and does a small amount of bookeeping work for the DesktopManager. So, the solution is the code I wrote to switch focus using the JInternalFrame's methods. Since I did not want to have to write those nine lines of code in the couple of places I want to programmatically switch the active frame I added a get/setActiveFrame method to my JDesktopPane derivative. In case others face this problem here is the code (warning I have not yet setup building the JavaDocs for this project so I cannot vouch for the validity of the JavaDoc, but the code does work):/**
* Bring frameToActivate to the front (restoring from icon if neccessary) and make it the
* selected frame. This method does all the things required to switch the active frame for
* an MDI application unlike: @link JDesktopPane.setSelectedFrame, which does not change the
* focus; @link javax.swing.DefaultDesktopManager.activateFrame which does not correctly
* handle iconified frames or switch the focus properly; and
* @link javax.swing.JInternalFramesetSelected which also does not handle iconified frames.
* @param frameToActivate the frame to bring to the front and become the active window
* @throws IllegalArgumentException
public void setActiveFrame (JInternalFrame frameToActivate) throws IllegalArgumentException {
    if (frameToActivate == null)
        throw new IllegalArgumentException ("setActiveFrame a frame must be passed a non null valie.");
    try {
        if (frameToActivate.isIcon ()) {
            // Restore from icon
            frameToActivate.setIcon (false);
        frameToActivate.moveToFront();
        frameToActivate.setSelected (true);
    } catch (PropertyVetoException error) {
* This method returns the currently active frame. This method returns the same frame
* as <code>getSelectedFrame</code> and is provided for symetry for <code>setActiveFrame</code>.
* @return the currently active frame
* @see LDesktopPane.setActiveFrame
* @see javax.swing.JDesktopPane.getSelectedFrame
public JInternalFrame getActiveFrame () {
    return getSelectedFrame ();

[Solved]Bash:Manipulating arrays of paths? the right way or not?

Note: Refer to the following posts for better solutions and/or alternatives.
This is a mock segment of a script I'm writting and I need to know if I'm doing it the correct way or at least in a proper bash way...
the following works but will it always parse in a sorted manner. I have a set of directories that are named by date in the YYYY-MM-DD (International) format and want to be sure that they will always be treated as directory paths even when special characters "\n,\t,\s ...etc" are encountered in the path. The number of these directories changes and is compared to a set NUM-ber variable and when there are more than the set number the oldest ones are removed which brings a second question. Being dated as YYYY-MM-DD they sort from oldest to newest(lexicographical order) but do they always and is this the right way to deal with elements in an array separated by nulls? Any Comments or suggestions would be appreciated as I'm learning bash for the time being (perl is next) and gathered this from bits and peices on verious wikis and forums. I basically want know if this a correct approach to the subject of extracting and performing actions on elements of an array that are directory paths.
#!/bin/bash
oifs="$IFS"
IFS=$'\0'
DIRTREE=(/path/to/dated/directories/[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]/)
NUM=5
HOWMANYMORE=$(echo $(( ${#DIRTREE[@]} - $NUM )))
if (( ${#DIRTREE[@]} > $NUM )) ; then
rm -rv "${DIRTREE[@]:0:$HOWMANYMORE}"
fi
IFS="$oifs"
Note:I have tested this for those wondering

there is a special syntax for appending elements to an array:

you can simplify to
NUM=3
combined=()

(( count= ${#new[@]} - NUM ))
combined+=("${new[@]:0:$count}")
done
This works as really well, however, in my case I still need the other sets in separate arrays for other purposes in my personal script so I adapted the approach a little and got this which uses the array+=(foo) syntax properly now. I was aware of this feature in bash arrays and experimented with it but had no success adding elements from other arrays until you demonstrated it in your example by adding them though a "for loop" and doing the arithmetic there... My current one now is very similar...I'm not sure how to reduce it further if possible but I need the other arrays as I do something completely different with them:
#!/bin/bash
NUM=10
set1=(/home/maat/datedfolders/set1/[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]/)
set2=(/home/maat/datedfolders/set2/[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]/)
set3=(/home/maat/datedfolders/set3/[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]/)
CT1=$(( ${#set1[@]} - NUM ))
CT2=$(( ${#set2[@]} - NUM ))
CT3=$(( ${#set3[@]} - NUM ))
for X in "${set1[@]:0:$CT1}" "${set2[@]:0:$CT2}" "${set3[@]:0:$CT3}"
do
combined+=("$X")
done
for
for Xdirs in "${combined[@]}"
do
rm -rv "$Xdirs"
done
I'm considering changing the title of this thread as it reveals a little more than I originally expected to go over and provides some pitfalls as well as ways to approach array manipulation which can be applied to wide range of uses in bash scripting. Others may find totally different uses for what we've discussed here so....

Which is the correct way to filter/block traffic between vlans?

Hi all. My question is: Which is the correct way to filter/block traffic between vlans?
i have a more than 15 vlans. I want to block traffic between them except 2 vlans.
source vlan 3 deny destination vlan 4
#access-list 100 deny ip 192.168.3.0 0.0.0.255 192.168.4.0 0.0.0.255
and the oposite:
#access-list 101 deny ip 192.168.4.0 0.0.0.255 192.168.3.0 0.0.0.255
I have to do this for all VLANs, ono by one. Is that right?
Thanks.

There are a couple of ways to achieve that. I assume that you have a Layer3-Switch. There I would configure one ACL per vlan-interface and allow/deny the traffic as you want. Sadly, the Switches don't support object-groups yet, so you have to use the IP-networks here. Only allow/deny traffic based on networks or hosts. Don't even try to be very granular with permit/denys based on ports. Because the switch-ACLs are not statefull you'll run into problems for the return-traffic if you woulf do that. And the return-traffic of course has to be allowed also.
Another way: with the help of 802.1x you can deploy port-based ACLs for every user. That takes some time for planning, but is one of the most powerful solutions.
For more control you could remove the L3-interface from your L3-switch and move that to your router or firewall. These devices support stateful filtering and you can control your traffic much tighter tehn with ACLs on the switch.
Don't stop after you've improved your network! Improve the world by lending money to the working poor:

Filter or Restrict on? Which is the best way to put it?

Hello Experts,
If there is a Characteristic/Key figure on a report in BEx, and I right click on it and find another data element say, 0FISPER it I EDIT. On right click on 0FISPER I a variable.
My question is this, do we way that the key figure is RESTRICTED ON 0FISPER
or, key figure is FILTERED by 0FISPER
When do we use Filter or Restrict on? Which is the best way to put it? How best is it read, please include the variable in your discussion.
I will appreciate this clarification.
e.g. Company code EDIT shows Company codes ZPPTcomp: with nodes 8000, 9000
Thanks.

Hi Amanda,
as per my understanding,
you are checking the structure field, you have selected edit then you are viewing a key figure and 0fiscper restricted by varaible. am I right?
if this is the case this is local selection and the key figure is restricted by fiscper variable means the restriction value user can enter in selection screen. if you select 0fiscper and select restrict there you can see single values, value range and you can also see varaible tab. by using varaible tab you can restrict to variable value.
hope this gives you some understanding.

Thread safety! Is this the right way?

Hello,
Lately I'm reading lot about thread-safety in Swing...
so just wondering that is this the right way to code ...
For ex following code executes(which makes DB connection and load some list) when user press the "connect (JButton)" ....
private void prepareAndShowConnBox()
        //System.out.println("prep - EDT: " + javax.swing.SwingUtilities.isEventDispatchThread());
        pwd.setEchoChar('*');
        javax.swing.Box box1 = new javax.swing.Box(javax.swing.BoxLayout.Y_AXIS);
        javax.swing.Box box2 = new javax.swing.Box(javax.swing.BoxLayout.Y_AXIS);
        box1.add(new javax.swing.JLabel("DB URL :     "));
        box2.add(db_url);
        box1.add(new javax.swing.JLabel("User Name : "));
        box2.add(uid);
        box1.add(new javax.swing.JLabel("Password :   "));
        box2.add(pwd);
        final javax.swing.Box box = new javax.swing.Box(javax.swing.BoxLayout.X_AXIS);
        box.add(box1);
        box.add(box2);
        int retval = javax.swing.JOptionPane.showOptionDialog(me, box,
                "Database Connection:",
                javax.swing.JOptionPane.OK_CANCEL_OPTION,
                javax.swing.JOptionPane.QUESTION_MESSAGE,
                null, null, null);
        if(retval == javax.swing.JOptionPane.OK_OPTION)
            status.setText("Connecting...");
            Thread t = new Thread(makeConn, "Conn Thread");
            t.setPriority(Thread.NORM_PRIORITY);
            t.start();
    }And the makeConn is....
private Runnable makeConn = new Runnable()
        boolean success;
        Exception x;
        public void run()
            //System.out.println("Con - EDT: " + javax.swing.SwingUtilities.isEventDispatchThread());

            x = null;
            try
                //load sun JDBC-ODBC bridgr driver...
                Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

                    t.start();
                else
                    status.setText("Connection Failed.");
                    showErr(x.toString());
    };Here uid,db_url (JTextField) , pwd (JPasswordField) , status (JLabel) are class fields.
Thanks for any comments... :)

Threading looks fine too me... the connection is created on a background thread, but (critically) all GUI updates are performed on the EDT, even if there's an exception. Well done.
My only comment is... why is your GUI creating a database connection at all? Ideally the controler would get the DAO (which would connect itself) and inject it (the connected DAO) into the view... but I'm a server-side boy, so feel free to ignore me.

Is this the right way - 9i

I have schema 'A' with few large and many small non-partition tables. I created another schema 'B' identical to 'A' and the only difference was that I partitioned the large tables resulting a combination of partitioned and non partitioned tables in schema 'B'.
I exported schema 'A' and imported it into 'B'. My question is, IS this the right way or I should done something else.
Thx

It would depend on the your goals, but I'd suspect that you would want to create most of the same indexes and views in the new schema. If you're partitioning the tables, though, you would have to give serious thought to how to define the indexes-- should they be global or local, should they be equipartitioned with the underlying tables, etc.-- which exporting and importing wouldn't resolve.
If the end goal of this exercise is just to produce the same schema with partitioned tables, transition any code & applications to the partitioned schema, and then drop the unpartitioned schema, creating the new schema just adds extra work. Create partitioned tables in the same schema (with slightly different names), load the data, create appropriate indexes, and then ALTER TABLE ... RENAME everything so that the partitioned tables now have the old non-partitioned table names.

Catcdb.sql is missing, which is the right workaround?

After creating a CDB the instructions ask you to run catcdb.sql, the file was not shipped on GA, this is reported as a bug (Doc ID 17316776.8) but I don't think there is a fix nor couldn't find an official workaround, should I run:
catproc and catalog instead?
I have not run anything but I believe the CDB is not completed until this is not done.
I left my CDB as it is and createt a PDB based on a non-CDB, one of the last steps is to run: @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql which I did but at the end of the script is trying to execute:
alter session set container = CDB$ROOT;
So now I'm getting the error: ORA-06553: PLS-213: package STANDARD not accessible
Which I believe is the result of not running catcdb on the CDB.
Anyway, could anyone clarify what's the right workaround? I don't want to mess up my CDB by running catalog and catproc and then find out I shouldn't have.
thank you all.

To solve the: ORA-06553: PLS-213: package STANDARD not accessible after alter session set container = CDB$ROOT;
I ran catproc and catalog however when attempting to create a PDB from a seed I got this error:
SQL> CREATE PLUGGABLE DATABASE PLUG1 ADMIN USER plgadmin IDENTIFIED BY plgadmin
FILE_NAME_CONVERT = ('/data1/oradata/PDBSEED/CDB1/', '/data1/oradata/PLUG1/'); 2
CREATE PLUGGABLE DATABASE PLUG1 ADMIN USER plgadmin IDENTIFIED BY plgadmin
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1 <--- fails once again a catalog problem
ORA-00942: table or view does not exist
This is because I only ran the catalog and catproc sql on the root but not on the seed, the right way to do it is to run them using catcon.pl supplied by Oracle and documented here:
Administering a CDB with SQL*Plus
But who really wants to read all this...copy and paste? go here:
oracle 12c: catcon.pl &laquo; Daniel Westermann&#039;s Blog
That solved my problem so far. If somebody knows what's the official way to fix the missing catcdb.sql script please let us know.

The "right" way to handle multiple devices, accounts and the cloud?

Perhaps a bit premature, but I figure it's never too early to start planning.
Here's our current setup - I currently have four iDevices in the faily (three iPhones and one iPod Touch. All are syncing to the same Mac Mini, albeit with different logins (and different iTunes store ids). All four of these are kept in sync via Home Sharing so we have access to the music/apps/etc acquired by the others.
Enter the iCloud - how does this fit in? What's the *right* way to do this?
I can see two options:
1)     Continue to utilize four iTunes store ids, sync them via Home Sharing and add four iClouds
     Advantages
          totally independent devices, users, etc.
     Disadvantages
          must pay for four "iTunes Match" services to access non-iTunes music on each of the four devices
          will iTunes-purchased music automaticaly sync to iCloud if it is shared via Home Sharing (or only by the original purchaser)?
2)     Use one iTunes Store id for all iDevices
     Advantages
          single point of acquisition and distribution for all devices
     Disadvantages
          need to find a way to merge IDs (is this even possible?)
Are there other advantages/disadvantages to these options? Are there other options? What's the easiest to set up and support? Any other thoughts?
Thanks in advance for your input.

Well it seems like the first thing you should do is consolidate your iTunes libraries so that you don't have 4 copies of everything, one for each user logged in to your Mac Mini. How you do that is consolidate all 4 iTunes folders to one folder located in the /Users/Shared/ folder and update each of your iTunes to point to that folder accordingly. That way you have one iTunes library, only one copy of your media, but accessible from multiple users.
One caveat is that if somebody is logged on and has iTunes open, you can't fast switch to another user and open iTunes. Apple made it so that only one user and one instance of iTunes can open a iTunes library at a time.
For your iTunes match situation, it does sound like you would be much better off sharing a single Apple ID with one iTunes Match. For consolidating, make sure you have everything everybody has shared via Home Sharing to the main account you'd like to move over to, and then simply go to each device Settings, Store, and the sign out of the original Apple ID and logon using the shared main Apple ID. I just looked at it and the automatic downloading is already live in iOS! You can specify if you want to do music, apps, and books separately in case you may want to automatically download music but not apps or books.
