Hi,
Permissions Issue on STANDBY machine?First problem I see is the sysdba password must be the same on both sides (target and auxiliary dbs).
From the documentation.
The source database and auxiliary instances must use the same SYSDBA password, which means that both instances must have password files. You can
create the password file with a single password so you can start the auxiliary instance and enable the source database to connect to it.Check all prereqs for the standby db duplicate here.

Hi San Rao,
1.Has the data request reached the SAP R/3..?
-check for the queue entries in the CRM out bound- SMQ1.
-check the destination for R/3 or ECC in CRM-SM59.
2.Has the data been extracted in R/3..?
-check for the short dumps in ST22 in R/3
3.Has the data been sent to the CRM..?
-check for the queue entries in the qRFC out bound queue- SMQ1.
4.If the the block number in the down load monitor shows 0 blocks in R3AM1 check the following
- check the destination for CRM in R/3- SM59.
-check which consumer is used for the object in the object management.
-check the table CRMCONSUM in R/3 if the consumer is active.
-check for the given consumer in table CRMFCPAR in R/3 if an entry exists for the object.
5.Has the data reached CRM..?
-check for the queue entries in the CRM inbound queue-SMQ2
-check in the flow trace SMW01 if there are Bdocs in error state.
-check for the short dumps in ST22 in CRM.
6.Check the table CRMFCPAR
-Table CRMFCPAR is valuated in the way that an entryfor a specific objectwill always be taken if it exists. If no specific entry exists, an entry with the object name ' * ' will be taken.the same goes for load type. If no entry exists, the initial load will be roll back to SMQ1 in CRM with a sysfail saying that no CRM is connected.
-If the flag 'DISCARDDAT is set to 'X' , no data is sent.
7. Status of the queue entries
-Queue name for a initial load start with R3AI.
-If queue entries exist in status READY, check SMQR (for SMQ1) orSMQR(for SMQ2). If the queue entries exists with the status SYSFAIL, analyse the error and restart the queue.
-If queue entries exists in the status 'RUNNING' wait for the load to finish.
-Never delete a queue entry manually.
Reward points if its helpful.

i am unable to aceess torrentz website.its coming that your IP address is abusing this server and most common reason is broken RSS reader

I have discovered it is most likely because you have Ad-Blocking software.
If your posting on a Mozilla site, then you probably (like me) use FireFox and probably also have the addon: AdBlock Plus, like I also do. I simply disabled on Torrentz.eu (also Torrentz.me would cause this problem) & when I refreshed it allowed me again.

CS4, what are the most pressing issues and are they solved ???!!!

I'll be visiting the Adobe booth at the IBC on the 15-th to have a sneak preview of CS4.
To properly report back what I have seen, I need a short list of the most pressing issues and what interests you most to see solved or added. Just to name a few of the topics:
1. 64 bit or 32 bit?
2. Support for 64 bit OS and which ones?
3. Matte problems solved? (BTW, what were the exact issues with mattes in CS3?)
4. Titler improvements?
5. What (new) video formats are supported natively?
6. What significant improvements are made in integration in the Suite?
I'm not looking for a repeat of the wishlist, just the most important issues to have a look at.
Looking forward to your suggestions.

Here is the news as I got it from one of the technicians and beta testers at the IBC, who showed some interesting things on the current beta version.
1. The RTM version is not ready yet. It will definitely be this year, but it will not be out in September. Most likely is around November and not all promised features will be available in the 4.0 version, but will be supplied by downloadable patches.
2. Interlacing/de-interlacing has not been solved. It is still the archaic approach from the '70-s era.
3. Vista 64 is officially supported, XP 64 is not officially supported, but runs without problems. Several beta testers have not seen any problems with XP-64. All applications are still 32 bit applications, apart from PS Extended, which is 64 bit. Parts of the memory model are ported to 64 bit. The first steps to porting all applications to 64 bit have been taken, but do not expect full support before CS5.
4. The major improvement has been in the project structure. Every project now has its own information about drive, directory and file structure as part of the project. Files in the project can have different properties in terms of resolution, i or p, so effectively this makes for Edius like capabilities, allowing for different sources in a single project, XDCAM-EX, HDV, AVCHD, P2 sources can be mixed and edited on the same timeline. You can move i material to a p timeline and edit from there.
5. Adobe Media Encoder is now a separate application.
6. Dynamic Linking has been improved significantly and encompasses AE, PP, EN in all directions.
7. Batch processing has been added. You can now add timelines to a render cue and continue editing on the same timeline and there seems to be some intelligence behind it as well.
8. OMF has been vastly improved.
9. The garbage matte problems have been solved.
10. Ultra is still a stand-alone application.
11. Improvements have been made to Encore, whether that includes closing the DVD was not really known.
12. Edit in Audition has been restored.
13. AVCHD is supported, RED support will be added (possibly even for CS3). Note that even on a 4-core MAC the editing experience with AVCHD is tiresome and horrendously slow. You may succeed in editing that kind of material, but only with 8-cores. Otherwise it is like editing HDV on a P4 @ 2.8 GHz with a single disk. It can be done, but it is not a pleasure. The CPU requirements are enormous and IMO most will be heavily disappointed that they need to upgrade their PC before any serious editing can be done, despite all the warnings given.
14. The titler has not been improved, but the strange windows problems (resizing) have been solved.
15. Dependency on Red, MainConcept and others make the delivery dates unsure, but it will take some time and new patches are already being worked on.
16. Adobe at IBC has only beta versions.
17. One member here (I will not mention names) is probably the best beta tester Adobe has ever had and this person beats all other beta testers by a wide margin in finding bugs. Thanks for all your continued trouble, NN. You will know who I mean if you are the person in question. One of your colleague beta testers was in awe of you.
The stability and integration of the suite has been vastly improved and tons of bugs have been resolved, so from that point of view, upgrading to CS4 looks very worthwhile. Initially however, third parties have to resolve some issues with their software, like Sony with their Clip Browser, which contains a serious bug, causing PP to crash completely. These bugs need to be resolved shortly and hopefully will be addressed before the RTM version comes out.

RMAN BACKUPS AND ARCHIVED LOG ISSUES

제품 : RMAN
작성날짜 : 2004-02-17
RMAN BACKUPS AND ARCHIVED LOG ISSUES
=====================================
Scenario #1:
1)RMAN이 모든 archived log들을 삭제할 때 실패하는 경우.
database는 두 개의 archive destination에 archive file을 생성한다.
다음과 같은 스크립트를 수행하여 백업후에 archived redo logfile을 삭제한다.
run {
allocate channel c1 type 'sbt_tape';
backup database;
backup archivelog all delete input;
Archived redo logfile 삭제 유무를 확인하기 위해 CROSSCHECK 수행시 다음과
같은 메시지가 발생함.
RMAN> change archivelog all crosscheck;
RMAN-03022: compiling command: change
RMAN-06158: validation succeeded for archived log
RMAN-08514: archivelog filename=
/oracle/arch/dest2/arcr_1_964.arc recid=19 stamp=368726072
2) 원인분석
이 문제는 에러가 아니다. RMAN은 여러 개의 arhive directory중 하나의
directoy안에 있는 archived file들만 삭제한다. 그래서 나머지 directory안의
archived log file들은 삭제되지 않고 남게 되는 것이다.
3) 해결책
RMAN이 강제로 모든 directory안의 archived log file들을 삭제하게 하기 위해서는
여러 개의 채널을 할당하여 각 채널이 각 archive destination안의 archived file을
백업하고 삭제하도록 해야 한다.
이것은 아래와 같이 구현될 수 있다.
run {
allocate channel t1 type 'sbt_tape';
allocate channel t2 type 'sbt_tape';
backup
archivelog like '/oracle/arch/dest1/%' channel t1 delete input
archivelog like '/oracle/arch/dest2/%' channel t2 delete input;
Scenario #2:
1)RMAN이 archived log를 찾을 수 없어 백업이 실패하는 경우.
이 시나리오에서 database를 incremental backup한다고 가정한다.
이 경우 RMAN은 recover시 archived redo log대신에 incremental backup을 사용할
수 있기 때문에 백업 후 모든 archived redo log를 삭제하기 위해 OS utility를 사용한다.
그러나 다음 번 backup시 다음과 같은 Error를 만나게 된다.
RMAN-6089: archive log NAME not found or out of sync with catalog
2) 원인분석
이 문제는 OS 명령을 사용하여 archived log를 삭제하였을 경우 발생한다. 이때 RMAN은
archived log가 삭제되었다는 것을 알지 못한다. RMAN-6089는 RMAN이 OS 명령에 의해
삭제된 archived log가 여전히 존재하다고 생각하고 백업하려고 시도하였을 때 발생하게 된다.
3) 해결책
가장 쉬운 해결책은 archived log를 백업할 때 DELETE INPUT option을 사용하는 것이다.
예를 들면
run {
allocate channel c1 type 'sbt_tape';
backup archivelog all delete input;
두 번째로 가장 쉬운 해결책은 OS utility를 사용하여 archived log를 삭제한 후에
다음과 같은 명령어를 RMAN prompt상에서 수행하는 것이다.
RMAN>allocate channel for maintenance type disk;
RMAN>change archivelog all crosscheck;
Oracle 8.0:
RMAN> change archivelog '/disk/path/archivelog_name' validate;
Oracle 8i:
RMAN> change archivelog all crosscheck ;
Oracle 9i:
RMAN> crosscheck archivelog all ;
catalog의 COMPATIBLE 파라미터가 8.1.5이하로 설정되어 있으면 RMAN은 찾을 수 없는
모든 archived log의 status를 "DELETED" 로 셋팅한다. 만약에 COMPATIBLE이 8.1.6이상으로
설정되어 있으면 RMAN은 Repository에서 record를 삭제한다.

Very strange, I issue following command in RMAN on both primary and standby machine, but it they don't delete the 1_55_758646076.dbf, I find in v$archived_log, this "/home/oracle/app/oracle/dataguard/1_55_758646076.dbf" had already been applied.
RMAN> connect target /
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
old RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
new RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
new RMAN configuration parameters are successfully stored

Yoga 2 Pro - Frequent issues after Tablet Mode and Suspend in Windows 8.1

Hi,
I bought a Yoga 2 Pro running windows 8.1 in December 2013. The machine runs fine, but from the beginning I experience frequent system issues whenever I have the Yoga in Tablet mode (display turned to the back).
The issues sometimes arise directly after I resume from tablet mode. More frequent the issues appear once I had the machine in tablet mode and after had it in suspend mode!
Some of the frequent issues that arise after I resume from tablet mode:
Power surge at right USB Port, where I have my mouse connected! The connected device cannot be provided with enough power. (Note, the left port still works), or
WiFi not working any more (No WLAN device detected, WLAN not functional), or
Bluetooth not working (No Bluetooth device detected, BT not functional)
All issues reliably disappear with a system restart!
I have already updated my drivers, scanned the Lenovo and Microsoft forum whether this is known without success and hope this avenue will bring me more luck.
What makes the bug hard to narrow down is that I do not have a recipe to reproduce the error. Not every time I turn the display in tablet mode the symptoms are equal! But what I can is that the tablet mode is the most common denominator I found so far.
Any helped/suggestions much appreciated.
Regards
   Florian

Yea, great... it seems like these articles and suggestions come up in the forum, and then there is always someone that says "it didn't work but this solved it for me" which ammounts to setting the screen at full brightness all the time.   LENOVO, HOW ABOUT FIXING THE ISSUE!!! It definitly has something to do with power, in my case _the only_ thing that fixes it is either plugging in a power cord or closing the screen, reopening it and hitthing the power button to turn it back on (both are REALLY annoying if you're trying to get work done).
I'm a fairly experienced IT guy, and I used to swear by _IBM_ Thinkpads and related laptops, then when they went to Lenovo a few years ago it seems like the support has gone to hell and the hardware appears nice but is sketchy (this thing should have never shipped with this display problem or the wifi card issues that it shipped with).   Honestly if issues like this don't get resolved Im not likely to order any more, ever. Not for my self or for my organization, we will stop persueing contracts with you and certifying the hardware for our work (though with the lenovo purchase it was deemed that the hardware wasn't certifyable for certine applications anyway). Yes, that will cost you a few thousand sales a year, which is a drop in the bucket for you, but I'm sure I won't be the only one.

UTF encoding issues on file adapters and mappings

Hi,
We did some tests regarding to UTF-8 and UTF-16 encoding using file adapters. Our conclusion so far is (when using Windows OS):
1. Inbound adapter can handle UTF-8 and UTF-16 correctly, but do not specify the encoding!
2. XI mappings will set the XML encoding to UTF-8 correctly when sending an UTF-16 file to XI.
3. Outbound adapter can only handle UTF-8 (and US-ACSII and ISO-8859-1) correctly.
The exact test results are:
>>Outbound file adapter bug.
If no encoding is specified in the outbound file adapter, UTF-8 and UTF-16 are handled correctly. However if the encoding is set to UTF-16, XI mapping will fail with the error:
During the application mapping com/sap/xi/tf/_CHRIS_OUTBOUND_TO_INBOUND_ a com.sap.aii.utilxi.misc.api.BaseRuntimeException was thrown: Fatal Error: com.sap.engine.lib.xml.parser.Parser~
Part of the trace:
com.sap.aii.ibrun.server.mapping.MappingRuntimeException: Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_CHRIS_OUTBOUND_TO_INBOUND_: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XMLParser: No data allowed here: (hex) a0d, a0d, 6e3c(:main:, row:3, col:2) at com.sap.aii.ibrun.server.mapping.JavaMapping.executeStep(JavaMapping.java:72) at com.sap.aii.ibrun.server.mapping.Mapping.execute(Mapping.java:91) at com.sap.aii.ibrun.server.mapping.MappingHandler.run(MappingHandler.java:78) at com.sap.aii.ibrun.sbeans.mapping.MappingRequestHandler.handleMappingRequest
>>Inbound file adapter bug.
If the encoding of an inbound file adapter is set to UTF-16 everything works ok (except the XML encoding is not set correctly, but this may be a mapping issue and not an adapter issue). However the default UTF-16 encoding seems to be UTF-16BE, where I would expect UTF-16LE since this is the most commonly used encoding.
If the encoding UTF-16LE or UTF-16BE the characterset used in the message is correct, except the BOM of the file. The BOM is empty which means UTF-8 encoded file. Since the file is UTF-16BE or UTF-16LE encoded, this is wrong and the correct BOM should be added by the adapter.
Encodings like US-ASCII and ISO-8859-1 are handled correctly.
>>Mapping bug
When we send in a message encoded in UTF-8 and want to send it out as a UTF-16 encoded message, we need to set the XML encoding to UTF-16. Normally this is done by an XSLT mapping using the <xsl:output encoding=UTF-16/> command.
The UTF-8 message will get processed by the XSLT and any special character will be converted to its UTF-16 value. However the output message is not UTF-16 encoded (1 byte in-stead off 2 bytes).
When this 1 byte message is send to the inbound adapter (encoding is set to UTF-16) the message will be translated from 1 byte to 2 byte (UTF-8 to UTF-16). The characters that were converted from UTF-8 to UTF-16 will be read as single byte characters and will be converted again. This will result in an incorrect message with illegal characters.
So basically characters will be converted to UTF-16 2 times, which is incorrect.
Maybe someone can confirm this on another XI system (maybe different OS). If you need test files or mapping, please let me know.
Kind regards,
Christiaan Schaake.

Update after carefully reading all the UTF related documents on the internet.
For UTF-16 the BOM is required and the adapter is handling this correctly. (encoding=UTF-16 will create the BOM).
For UTF-16LE and UTF-16BE the BOM must not be set. The application should be able to handle the conversion. The adapter is working correct again.
If the adapter is set to binary mode in stead of the text mode, the file will always be read correctly.
About the mapping issue, I'm still experimenting with this one.
Kind regards,
Christiaan Schaake.

Most common errors in submitting book created in iBA to iBooks?

I'm getting ready to submit a book I've created in iBooks Author to the iBooks store. (Still waiting on approval from iTunes Connect.) Judging by discussions in this forum, many submissions fail because of problems with the iBA file that is sent to iBooks. I'm wondering what the most common mistakes are--so I can avoid them! My book looks fine on my iPad in preview but I have a feeling iBooks will have numerous issues with it when I submit it. What kinds of things should I be aware of so I don't get "ticketed" by iBooks?

Has anyone received an update on apple tv issue with HD movies and what they are doing about it

Has anyone received an update on apple tv issue with HD movies and what they are doing about it

Whatever the rep told you, it is complete nonsense. There is clearly a problem at your end, the Apple TV 3 is capable of more than the Apple TV 2, and you clearly have the Apple TV 2 working perfectly. Since the Apple TV 2 is able to download from the Internet properly, then my suspicion would be your problem lies on your local network. Interference is a common problem on local networks.
Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

Scrolling issues on "IPod touch" and "IPad mini"

Hello,
I have a public website in SharePoint Office 365.
With mobile redirect off, the vertical scrolling on IOS devices are very slow. This is not the case with my Samsung notepad phone.
My question is: are there rendering and scrolling issues with IOS devices with SharePoint.

The most common problem you will find using SharePoint 2010 in Google Chrome is the missing scrollbar. This issue can be easily solved by replacing 1 line of code. Yes,
ONE line.
Step 1
In the Master page, look for this:
<body scroll=”no” onload=”javascript:_spBodyOnLoadWrapper();”>
and replace with this:
<body scroll=”no”>
<script type=”text/javascript”>$(document).ready(function()
{if (typeof(_spBodyOnLoadWrapper) != ‘undefined’) {_spBodyOnLoadWrapper();} });</script>
Step 2
THAT’S IT. Hopefully the scrollbar should appear
in Google Chrome.
You can find dozens of other solutions online, but I found that this one is easy to integrate, and doesn’t cause any other known issues.

Connectivity issues between Cisco 2901 and Cisco SG300-52

Hello,
I am having some serious connectivity issues between the hosts in my LAN.
My LAN is based on a Cisco 2901 router and a Cisco SG300-52 port switch.
The issue that has been happening is that connections between hosts on the LAN (remote desktop, extended ping, etc) is very unstable, at some point I can see a 35% lost packets on an extended ping. This happens at any time of the day and from any host.
All hosts are on the same Vlan(default Vlan) and on the same subnet. Some hosts have fixed IP addresses (servers and network equipment) and others obtain their IP address trough a DHCP reservation established on the router (reserved with the MAC address of every host).
I can provide further details if needed, because this issue is very serious and I would really appreciate any insight or support.
Many thanks in advanced.

EDIT: After doing every test we could think of, we finally found the reason behind this problem.
It turns out that the switch has problems handling communications between clients at different speeds, because most of the hosts connected were working at 100 Mbps but the servers were working at 1000 Mbps (and the communication between host and servers wasn't stable).
After manually setting the speed on all ports to 100 Mbps the problems have stopped.
Many thanks for you help on this issue.
