Upgrade from XI 3.0 (SP17) to PI 7.0 (SP12): Best Practices

Hi mates,
I've a few questions regarding the upgrade to PI 7.0.
If the upgrade process is done in phased manner i.e. DEV, QA, PRD in that order over a period of 3 weeks,
How do we handle the transports from DEV->QA->PRD when DEV is 7.0 and QA & PRD on 3.0 using CMS?
Will there be inconsistencies when transports are moved, because a few features could be different or internal representation of IR/ID content could be different in 3.0 & 7.0?
What are the upgrade best practices, phased manner or all at a time?
Please throw more light on this. I appreciate the inputs from people who've helped clients upgrade from 3.0 to 7.0. Any SAP documentation related to this?
I looked at the thread Transports from XI 3.0 to PI 7.0 but the answert is very generic, w/o any supporting documentation and real time experience.
thx in adv

Im my experience you should implement a change freeze for this period, with the exception of emergency transports - and these have to be justified.
> Will there be inconsistencies when transports are

Full regression testing will be needed on each interface. If you implement a change freeze this process becomes easier

Allow plenty of resources to fully test every interface, as you would with any upgrade.
You could also take the time to implement the new <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/80bbbd55-5004-2a10-f181-8bb096923cb6">CTS+</a> for this new version to avoid any further transport issues (PI7.0 SP12 +). A new method for a new system!
Also, how is your SLD set up for XI? This can have an impact.

Will i loose data, in outlook mails when i upgrade from OS X 10.9.5 to Yosemite

i am using a mac pro late 2013 version. at presen have os x 10.9.5, looking forward to update to OS yosemite. i am afraid that i would loose my data in my computer, especially will my outlook mails will be deleted . need to know wether we will loose data while upgrading the OS.

A few users have reported data loss while upgrading Mac OSX or even after updating Office. So, the best practice would be to export all email data in OLM format using outlook and also to save a copy of Microsoft User Data folder with Main Identity at a separate location such as a portable Hard drive and then only update the Mac OSX or outlook. This way if you face any issues, you have an option to go back to mavericks and get the things working exactly as they are now or alternately recover emails from the backup if you wish to stay on new OS.
I also upgraded to Yosemite and lost many outlook files and folders. I did not had any backups and was stuck completely. I researched and came to know that outlook stores messages in olk14 format. Then, I looked online for olk14 message recovery as I had some very important emails downloaded in outlook and didn't expect it to stop functioning by just upgrading Mac OSX. However, at a later stage I was able to recover messages from olk14 format. Though it costed a bit, but I was happy to get my email messages back.

SAP Best Practice For Unicode Upgrades - NetWeaver 2004s

Team SAP,
I have a customer that is starting to plan for a Unicode upgrade. The question from the customer is as follows:
What is the SAP Best Practice for Unicode Upgrades? They will be upgrading from a BW 3.5 System to NetWeaver 2004s, and their question is ... should they:
a) Perform the Unicode Upgrade At The Same Time As Their BW 3.5 > NetWeaver 2004s Upgrade, or
b) Perform NetWeaver 2004s Upgrade first, and then at a later date, perform the Unicode Upgrade?
Thank you in advance for any guidance or counsel you may be able to offer.

Best practice for linking fields from multiple entity objects

I am currently transitioning from PHP to ADF. I'm looking for the best practice for linking data from multiple entity objects.
Example:
EO 'REQUESTS' has fields: req_id, name, dt, his_stat_id, her_stat_id
EO 'STATUSES' has fields: stat_id, short_txt_descr
'REQUESTS' is linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.his_status_id
'REQUESTS' is also linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.her_status_id
REQUESTS.his_status_id is independent of REQUESTS.her_status_id
When I create a VO for REQUESTS, I want to display: REQUESTS.name, REQUESTS.dt, STATUSES.short_txt_descr (for his_stat_id), STATUS.short_txt_descr (for her_stat_id)
What is the best practice for accomplishing this? It appears I could do it a few different ways:
1. Create the REQUESTS VO with a LOV for his_stat_id and her_stat_id
2. Create the REQUESTS VO with the join to STATUSES performed within the query for the VO. This would require joining on the STATUSES EO twice (his_stat_id, her_stat_id)
3. I just started reading about View Links - would that somehow do what I'm looking for?
I also need to be able to update his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr from a dropdown.
Any suggestions on how to approach such a stupidly simple task?
Using jDeveloper 11.1.2.2.0 if that makes a difference in the solution.
Thanks ahead of time,
CJ

CJ,
I vote for solution 1 as it's just your use case. As you said you what to update the his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr by a drop down. This is exactly the LOV solution.
ViewLinks are used fro master detail navigation (which you don't do here) and Joining the data make it difficult to update (and you still need a LOV for the drop down box.

Is it really possible to upgrade from a Treo 650 to a Treo 750?

I am not a very happy customer at the moment, but any help would be greatly appreciated. I upgraded from my old Palm Tungsten to a Zire, then to a Cingular Treo 650, combining three devices into one. I have since discovered that the Treo 650 seems to have a faulty transmission mode, as I can rarely be clearly understood by whomever I call. Am on the second (or third, I have lost track) and continue to have the same problem. I get five bars of reception but can't be understood on the other end. A bit of a problem when one is trying to call 911. Am constantly told I am "breaking up". The repair shop says it "Can't duplicate the problem". OK, then I do not want to give up all the info I have stored in the fool thing, and the 750 seems to have a different system, so I thought I would try that. All the stuff I could find seemed to indicate it wouldn't be a problem to upgrade. When the 750 arrived, I tried to install the software from the CD on my Windows XP computer. No dice. Setup encounters an error and closes. Can't even look at the files, because setup tries to run any time I access the CD. From any drive. Gave it to my girlfiend to check on her computer, and the CD seemed to run fine. Other CDs work just fine on my computer. Must be some kind of conflict, but what? Tried calling the AT&T number that suggested they could help with setup, and was first connected to the business center, they routed me to the laptop center, who routed me to the network center, who said they would have to bring in the Palm customer service and connected me to a Mac guy that dumped me back to a menu that took me to someone for whom English is a second language with whom I was trying to communicate over a very poor satellite connection. They made no sense anyway. telling me first that I couldn't have two desktops running (wrong, my girlfriend has my old Zire and the CD worked fine) and then insisting that the serial number on my device had to start with a P, when it clearly does not have any alpha characters in it. Gave up on that route of assistance. Managed to get the new ActiveSync installed from my girlfriends computer over the network. Great. Now let's get my 650 synced with Outlook (which I have not used at home) and see if we can move on. Nope. First I have to update Outlook 2000 from the old Win98 to my current XP. Find the old CD, and square that away. OK, now sync to Outlook. Nope. The sync program gives an error, saying it will only sync with Outlook 98, 2000, and XP(2002). Good grief. I have Outlook 2000, and the software apparently does not recognize it. If the Palm doesn't work, there is no reason for me to keep this phone, and I am very close to returning it and abandoning the Palm entirely when I upgrade to something that works, although I dread re-entering all that information.

Thanks for the feedback. Today I installed an Enterprise version of Office 2007 I purchased a while back, but had not yet installed. Microsoft presented a few challenges, but they were quickly resolved. I then downloaded the appropriate conduit from Palm, and synced the 650 with the handheld overwriting the computer. Then used Active Destop to sync the 750. Satisfied I had moved as much info as possible, I called AT&T and had them move the phone number to the new Treo.
Bonus! When the guy at AT&T called me on the new phone to verify it, he said it sounded better than my landline.
Sorry for the streaming paragraph. When it is late I tend to write like I think.

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine until I deleted an app in error. When I downloaded it from iTunes, my account is no longer recognized by the app's host servers. Can I go back and re-sync one app from my old phone?

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine. Yesterday I deleted an app in error. When I downloaded the software it from iTunes ( did this many times on the old 3GS), my account is no longer recognized by the app's host servers (Playtika), even though it did after the initial conversion. Can I go back and re-sync just one app from my old phone?

Try deleting what is called the iPod Photo Cache.

Can't print from IE 8 after upgrading from Vista to Windows 7

My laptop (HP Elitebook 8530w) uses two HP printers: Color LaserJet CP3525x (at work) and Deskjet 6940 (at home). Both printers are accessed across a local network.
I recently upgraded from Vista Enterprise to Windows 7 Enterprise.
Everything still prints fine (from Word, Adobe Reader, Windows Photo Viewer, etc.), except for IE 8! When I try to print a web page from IE, it prints only the page header, and otherwise the sheet is empty. This symptom occurs on both printers. (And of course this worked fine before the upgrade.)
Any ideas? Thanks for any help.

If anyone else is having this problem, I found the solution on another forum (http://social.answers.microsoft.com/Forums/en-US/InternetExplorer/thread/920588e5-ccc4-4e24-83d6-606...).
Specifically, the following steps solved the problem:
1. If it doesn't already exist, create a directory named "Low" in your directory "C:\Users\<your_user_name>\AppData\Local\Temp\".
2. From a command prompt, issue this command: ICACLS C:\Users\<your_user_name>\AppData\Local\Temp\Low /setintegritylevel (OI)(CI)low

Fields in read-only mode for BP transaction in upgrade from 4.72 to ECC6.0

Hello,
This is regarding the query for BP transaction in upgrade from 4.72 to ECC 6.0.
While creating BP / Changing BP system is disabling the fields in compnay code & sales area option. There is a SAP not provided 907860; and specified that the proplem is because of the delta customizing.
All the customization settings are as per the note. And the Synchronization Control is also activated. But still the fields are disabled only.
I have checked the field settings also in Cross-Application-Components & Logistic-Genral.
But these are not working for compnay code & sales area data.
please let me know if anyone has faced this type of problem / found any solution on this.
Best Regards,
Shubhada

SAP IMG -> Cross Application Components -> Master Data Synchronization  Synchronization Control -> Synchronization Control -> Activate Synchronization options
This setting allows you to activate synchronization of BP with R/3. Not maintaining the values may result in certain fields being read-only in BP.
Suggested Values:
Source Object: BP | Target Object: CUSTOMER | Active Indicator : X
Source Object: BP | Target Object: VENDOR | Active Indicator : X
Source Object: CUSTOMER | Target Object: BP | Active Indicator : X
Source Object: VENDOR | Target Object: BP | Active Indicator : X
Have you set all of the above settings??

Slow table creation after upgrade from 10.2.0.3 to 11.2.0.1 using DBUA

I've recently completed a database upgrade from 10.2.0.3 to 11.2.0.1 using the DBUA.
I've since encountered a slowdown when running a script which drops and recreates a series of ~250 tables. The script normally runs in around 19 seconds. After the upgrade, the script requires ~2 minutes to run.
By chance has anyone encountered something similar?
The problem may be related to the behavior of an "after CREATE on schema" trigger which grants select privileges to a role through the use of a dbms_job call; between 10g and the database that was upgraded from 10G to 11g. Currently researching this angle.
I will be using the following table creation DDL for this abbreviated test case:
create table ALLIANCE (
 ALLIANCEID NUMBER(10) not null,
 NAME VARCHAR2(40) not null,
 CREATION_DATE DATE,
 constraint PK_ALLIANCE primary key (ALLIANCEID)
 using index
 tablespace LIVE_INDEX
tablespace LIVE_DATA;When calling the above DDL, an "after CREATE on schema" trigger is fired which schedules a job to immediately run to grant select privilege to a role for the table which was just created:
create or replace
trigger select_grant
after CREATE on schema
declare
 l_str varchar2(255);
 l_job number;
begin
 if ( ora_dict_obj_type = 'TABLE' ) then
 l_str := 'execute immediate "grant select on ' ||
 ora_dict_obj_name ||
 ' to select_role";';
 dbms_job.submit( l_job, replace(l_str,'"','''') );
 end if;
end;
{code}
Below I've included data on two separate test runs. The first is on the upgraded database and includes optimizer parameters and an abbreviated TKPROF. I've also, included the offending sys generate SQL which is not issued when the same test is run on a 10g environment that has been set up with a similar test case. The 10g test run's TKPROF is also included below.
The version of the database is 11.2.0.1.
These are the parameters relevant to the optimizer for the test run on the upgraded 11g SID:

So while this certainly isn't the most elegant of solutions, and most assuredly isn't in the realm of supported by Oracle...
I've used the DBMS_IJOB.DROP_USER_JOBS('username'); package to remove the 194558 orphaned job entries from the job$ table. Don't ask, I've no clue how they all got there; but I've prepared some evil looks to unleash upon certain developers tomorrow morning.
Not being able to reorganize the JOB$ table to free the now wasted ~67MB of space I've opted to create a new index on the JOB$ table to sidestep the full table scan.
CREATE INDEX SYS.JOB_F1_THIS_NEXT ON SYS.JOB$ (FIELD1, THIS_DATE, NEXT_DATE) TABLESPACE SYSTEM;The next option would be to try to find a way to grant the select privilege to the role without using the aforementioned "after CREATE on schema" trigger and dbms_job call. This method was adopted to cover situations in which a developer manually added a table directly to the database rather than using the provided scripts to recreate their test environment.
I assume that the following quote from the 11gR2 documentation is mistaken, and there is no such beast as "create or replace table" in 11g:
http://download.oracle.com/docs/cd/E11882_01/server.112/e10592/statements_9003.htm#i2061306
"Dropping a table invalidates dependent objects and removes object privileges on the table. If you want to re-create the table, then you must regrant object privileges on the table, re-create the indexes, integrity constraints, and triggers for the table, and respecify its storage parameters. Truncating and replacing have none of these effects. Therefore, removing rows with the TRUNCATE statement or replacing the table with a *CREATE OR REPLACE TABLE* statement can be more efficient than dropping and re-creating a table."
