Two machines using syncing to one database.

We're in development/eval for 7.0 Portal right now, and every time we sync to another
machine the other machine(s) stop working and get "Null Portal Object" webflow
exception. Is there a way to have multiple people hitting one database? We're
thinking of letting each developer have her/his own BEA instance on her/his machine.
Steve

Steve,
There are two ways to solve the problem of which one I know is described in
the developers guide:
1. Each developer should have his own enterprise application (e.g.
developer1_app, developer2_app). The synchronization works by the
enterprise id and I believe it's immediately propogated to the in-memory
repository even when the developer is on another workstation. Separating
the namespace by enterprise application name will solve that.
2. Create separate database instances. This is the approach we took and
it works fine. Everybody datasyncs in private now against the same
<application-project> directory stored in our CMS.
Hope that helps,
Wayne

Keeping two machines 100% synced

Here is my setup:
1. MacBook Pro with 128 Gb SSD boot drive and 1 Tb secondary drive (using a caddy in place of SuperDrive)
2. Mac Pro desktop with 128 Gb SSD boot drive and 1 Tb secondary drive (have additional drives in remaining 2 slots, but they aren't relevant to this)
I use the MBP in the field when shooting video and photos to dump files, do quick views and minor edits, even some minor word processing if I am on a client site and need to generate a form, and email/web searches, etc. At home, I will sometimes use the MBP for full editing in a secondary office.
I use the MP for pretty much the same thing apart from the portable aspect.
Here's my question/desire/wish:
Is there a method or application whereby I can keep these two machines 100% synced once the MBP rejoins my home network?
Example 1: I store the video/photo files on the 1 Tb secondary drive of the MBP. When the MBP arrives home, it should immediately start syncing those files over to the MP's 1 Tb secondary drive in the same folder structure.
Example 2: I install a new application on the MP. That application (or files which the installer puts into place on the MP) get automatically installed or copied to their respective locations on the MBP.
Example 3: I begin editing a Premiere project on the MBP. I save it, get up and walk to the other office and sit down at the MP and open the same project and pick up where I left off on the MBP. And vice versa.
Essentially what I am looking for is a "roaming profile" set up but with the redundancy of having two locations for everything, kept in total sync with each other, and reflecting changes as I make them, near simultaneously.
Ideally, and to make matters even more complicated, I would like this same set up to work with an additional machine, my wife's iMac. She shoots alongside me in the field and we could both dump our files into the MBP, do whatever initial work needs to be done, and then pick up at home, she on her iMac looking at her photos, and me on the MP editing video.
I'm suspecting a possible solution involves a series of Automator scripts and folder actions, but I was hoping to find a more elegant, one-click idea. Thoughts? Suggestions? Flame for requesting an entirely unreasonable feature?

Synchronizing data between devices is a complex issue, and there's no really ideal solution. This comment is an oversimplification.
Mail can be synchronized by storing it on a mail server that uses the IMAP protocol, such as iCloud. The mail stays on the server, so it's automatically in sync with all mail clients.
Several other kinds of data can be synced via iCloud, such as calendars, iWork documents, photos, Safari tabs and bookmarks, and keychains. Some third-party applications can also sync with iCloud, but not many. iCloud is easy to use, for the most part. The drawbacks of using it are, first, that it doesn't sync everything; and second, that some of your private information will be in the hands of strangers. Read the iCloud feature list and privacy notice carefully before deciding whether or how to use it. There should be no privacy concerns with iCloud keychain, because the data is encrypted end-to-end and is not accessible to anyone at Apple—but you have to take Apple's word for that.
A more comprehensive solution, and one that doesn't raise any privacy issues, is to set up an OS X Server on your network and create mobile accounts on your other Macs. You will then be able to synchronize all files in the home folder automatically at logout, or at any other time manually. The main drawback here is that OS X Server would be hard for most non-technical users to set up and maintain. Another is that the synchronization only works with Macs, not mobile devices.
Third-party software such as Unison can also be used to synchronize files over a network. Unison is free, but it's not easy to set up in a way that doesn't lead to conflicts when files are modified on different devices between synchronizations. To synchronize more than two Macs in this way, you'll want to use one as the master, and sync between it and the others.

Create a new database on machine which already has one database running?

Hi,
How can I create a new database on machine which already has one database running on Windows platform?
I am totally new to DB and this is the first time I am creating a database.
When I installed Oracle on windows platform database MYDB got created.
Now I want to create another database with the following command on the same machine.
CREATE DATABASE TESTDB
     DATAFILE 'F:\oracle\oradata\testdb\system01.dbf' SIZE 250M REUSE
     CHARACTER SET US7ASCII
LOGFILE
     GROUP 1 ('F:\oracle\oradata\testdb\redo01.log') SIZE 10M,
     GROUP 2 ('F:\oracle\oradata\testdb\redo02.log') SIZE 10M;
But it doesn't work. I unmounted the DB MYDB and then again tried above command. But still didnt work.
How can I create a new database on machine which already has one database running on Windows platform?
Any sort of guidance is appreciated. Thanx in advance.

Use DBCA.its a GUI tool for creating the database.

Need help to join two tables using three joins, one of which is a (between) date range.

I am trying to develop a query in MS Access 2010 to join two tables using three joins, one of which is a (between) date range. The tables are contained in Access. The reason
the tables are contained in access because they are imported from different ODBC warehouses and the data is formatted for uniformity. I believe this cannot be developed using MS Visual Query Designer. I think writing a query in SQL would be suiting this project.
ABCPART links to XYZPART. ABCSERIAL links to XYZSERIAL. ABCDATE links to (between) XYZDATE1 and ZYZDATE2.

Thank you for the looking at the post. The actual table names are rather ambiguous. I renamed them so it would make more sense. I will explain more and give the actual names. What I do not have is the actual data in the table. That is something I don't have
on this computer. There are no "Null" fields in either of the tables.
This table has many orders (MSORDER) that need to match one order (GLORDER) in GLORDR. This is based on MSPART joined to GLPART, MSSERIAL joined to GLSERIAL, and MSOPNDATE joined if it falls between GLSTARTDATE and GLENDDATE.

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.

Can I use more than one database connections in a jdeveloper project?

I use jdeveloper version 9.0.4.0 (build 1407),Can I use more than one database connections in one jdeveloper project?

9.0.4 is a fairly old version, so you may only find a few people who know how it worked.
Assuming you're using ADF BC, once known as BC4J, once know as JBO, in the project, and that the architecture hasn't changed much, then the answer is only 1 connection per project.
Programmatically you're free to use as many connections via JEE as you see fit, but ADF BC is limited to one connection.

HT201250 I have two macbooks. Can I backup both machines using timemachine on one external hard drive?

I have two MacBooks, both operating on different OS - Leopard and Snow Leopard. Can they both be backed upusing time machine onto one external hard drive?

J D McIninch wrote:
Actually, it does both. However, if you use two machines with the same name, it can pose a problem. If you mount the Time Machine drive and open the backup db directory, you'll note that the subdirectories are arranged by system name. The information about the ethernet MAC ID is in hidden files.
Yes, as posted, to the user it's confusing (and accessing your backups via the Finder is not recommended).
Time Machine knows which is which, and will back up each Mac to the proper folder. When/if you want to use the "Star Wars" display to view or restore from either Mac's backups, it will show the backups for the Mac you're on.

Two emagent-Services on a one Database system

Hello,
maybe someone can answer my question, which I am working on since several days.
I installed Oracle 10g Database and created a Database, after that I had one OEM running and accessible using the normal URL host:1158/em.
After installing Oracle HTTP-Server and Application Express there is another OEM-Service running, that I cannot access.
I had a look at the Process and Port-List and found out that one is started from the Database_Home and the other from the Http_Home.
In the Port-List there was one java.exe on Port 1158, which I can access, and another two listening on 1810 and 1850 which I am not able to access.
Furthermore there are two emagent processes shown, where one has two connections established on different ports and is listening on a third and the second process is listening on a single port.
Since both processes have there own java instance running, consuming dozens of MB virtual and RAM space, I would like to know if I really need the second emagent that I probably installed with the HTTP-Server.
And if I do not need it, how I can stop it, because there is no entry in the Windows services list to stop this service.
Kind regards
Alex

Are you sure that while installing the Application Express you did not create a new database instance? I think that windows starts one emagent for each DB instance that has been created. It might be that installing Application Express you accidentally created a new instance? Or maybe you did the DB creation process more than once without dropping the previously created instance? I remember I used to have 4 instances running, each of them with their processes and my system became very very slow.
In the Oracle_Home/install/portlist.ini there is the list of the ports used by EM and in this file are shown even the previously configured instances EMs even if those instances have been dropped - but the processes should no longer been lunched.
For each instance, in this file the EM shows 2 different ports, one is the HTTP port (in your case 1158) and the other one is the EM agent port to connect to the instance. I have the feeling that one the ports you mentioned 1810 or 1850 should be this port (mine is 1830). You will not be able to access these ports via HTTP. So having one of them in use besides the HTTP service on 1158 should be fine.
Still I think it should not be the case to have 2 EM processes running unless you have 2 instances still active. Are you sure these java.exe processes are EM processes?

Want to have two iPhone's syncing to one iTunes account - possible?

I flip between the US and UK - I have a UK iPhone but am about to buy a US phone - I want them both to sync to one account so they replicate each other - can this be done

I can also state that yes you can do this as I have 2 iPhone's and an iPod touch synced to the same account. I've split the apps between the 3 to better manage my content i.e. (movies on one phone, games on the iPod, and music and podcasts only on my main phone.)

Two apple Ids syncing with one computer

I have to back up every single one of my songs because they are going to be removed from my ipod when I update it. Why the **** does apple do this? How the **** do I go about this ridiculous situation!?!?!

You can authorize one computer for more that one account.. To do some thing you will have to sign out of one account in iTunes>Store>Signin/SIgn-SIgn out

Two iphones separatly synced to one icloud account

I have my iphone synced to an icloud account. My husband has just got an iphone too which I have syned to a icolud account using the same email address but the problem is all my calendar information and contacts are now synced to my husbands phone. Can you have one icloud account but two accounts one for each mobile phone? Hope I have explained this correctly, as not sure what I am doing wrong!!!!!

Welcome to the Apple Community.
To begin with, I would like to try to explain Apple's confusing nomenclature in regard to iCloud.
Apple have called the whole cloud thing iCloud, there are a number of features under the iCloud umbrella, some of which require their own login. iTunes is one of these, another is what Apple have unfortunately also called iCloud too.
You can use the same Apple ID (account) to login to both iCloud and iTunes, but you don't need to and often users will login to each service using a different ID.
The part that you need to remember is that the services available when you log into iCloud are completely different and unrelated to those when you log in to iTunes. Your iCloud login enables mail, contacts, calendars, find my phone, Back to My Mac, Documents & Data sharing and photostream, it does not affect any of your iTunes services.
To avoid confusion when discussing your problem, when I mention iCloud, I am referring to the services under the iCloud login, Whereas I will refer to the whole cloud thing as The Cloud.
I would suggest in your situation that you each have your own iCloud accounts for your own mobile device, whether or not you wish to share an iTunes account you will have to decide.

ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0.2/dbhome_1
ORACLE_SID=mydb
The mis-matched cases stem from my predecessor deciding he didn't like database names in lower case, so started changing in mid-stream. I'm not sure exactly what he did or how he did it. But that aside, the results of creating a new dbcontrol (getting two directories for the same database) still puzzling. I started by dropping the original (emca -deconfig dbcontrol db -repos drop), which dropped the upper-case version of the directories, but left the lower-case version. I then deleted that manually before running emca to configure a new dbcontrol, but still ended up with both versions.
Ideas?

The ORACLE_HOME may have been set twice with differents values in it (i.e. extra slash) before starting twice the same db.
Please, have a look to this article from Ivan Kartik :

Two Machines on Same Modem - One IP address !?!

This isn't actually a Mac question, but all the smart people are here...
I have a cable wireless modem (Linksys) with one (iMac) machine plugged into it via Ethernet, and another (Mac) "attached" via wireless Airport.
When I go to WhatIsMyIP.com (or grc.com, or any other site that detects my IP address) from either machine I see the SAME IP address for both machines.
How can this be? I though addresses were unique. The machines certainly behave as if they were on different addresses - email goes to the right place, &c.

jstackpo,
You are dealing with two things here: The internet as a whole, and the "intranet" that your router creates and manages.
As far as the internet goes, you are correct in the assumption that a single, unique IP address is necessary. However, it is your router, and through the router your entire "intranet," that receives this unique IP address. When the router is powered on, it connects your your ISP's "DHCP" server to request an IP address. When granted, this becomes your "public" IP address, and it is assigned directly to your router. The router then uses a protocol called "Network Address Translation" (NAT) to share that single IP address between all of the connected computers. How does it know to send some information to one computer, and something else to a second computer? Without getting long-winded about it, it knows this the same way your computer knows to send a song you may be downloading from the iTunes store to iTunes, while at the same time sending a Youtube video to Safari.
You can think of your own network (your "intranet") as a mini internet, in that all the computers within it must have unique IP addresses. This same principal applies to your router, as it is seen from other computers on that network. Typically, routers use the IP address range of "192.168.x.x" for the entire network, but there are many choices an administrator can make is this regard. In creating this "private" network, the router acts as a DHCP server in it own right, granting these internal IP addresses as machines connect to the network and request them (just as the router does when it connects to your ISP's DHCP server).
So yes, there are at least three IP addresses involved: 1) Your "public" IP address, requested by your router and granted by your ISP's DHCP server, which applies to your router, and through it every other machine on your network (as they are seen by the internet at large). 2) Your router's self-assigned "private" IP address, as seen by every computer on your network. 3) The additional "private" IP addresses given to the various computers on your network, assigned by your router via its own DHCP server.

If my backup HD is not large enough, can Time Machine use more than one destination HD?

Hi, I have about 0,8 Tb on my Mac + 0,9 Tb in an external HD + 2,5 Tb in another external HD.
I have plenty of other HDs with 1-2 Tb that I could use as backup. Can I use them in Time Machine? Can Time Machine split all the data from my Mac and source HDs in more than one destination HD? I would love it if I could avoid buying large 6-10Tb HDs; they are still expensive... I'll appreciate your kind inputs!

Technically, you could store parts of your backup on different drives, but it would require you to be constantly changing the items excluded. It is designed to be a single backup, which you can do the entire backup to more than one drive.

Two Machines backing up to one sparse bundle

My wife recently migrated from a MacBook to a MacBook Pro. She was using TM to backup to Time Capsule. We set up a new user account on the old MacBook for my daughter and changed the computer name in sharing preferences on BOTH machines to initiate brand new backups for each. MacBook Pro was initially backed up to a new volume, but then switched back to backing up to the original sparse bundle. The MacBook is also backing up to the same bundle although both machines have different names. What's going on and how do I fix it? My gut tells me to start over by restarting TC and deleting old sparse bundles before backing up each machine. Any suggestions?

TM does not go by computer names when you are doing TM backups. it tags the sparse bundle with the MAC address of the computer which is a unique identifier. but in Snow leopard TM also lets you continue using an old sparse bundle when you use Migration Assistant to migrate to a new one. I guess that's what happened to you. I think the only way out at this point is to delete the sparse bundle where both computers are backing up now. you can simply trash it and empty trash or you can wipe the TC drive as you were intending this will of course delete it too. I would also reset TM preferences on both computers. after deleting the sparse bundle delete the file /library/preferences/com.apple.timemachine.plist. then go to TM system preferences and set up TM. do it on both computers.
