Problem with the result of multiple queries in Web Intelligence (BO XI R2)
We have a problem with Web Intelligence reports. Behavior of the results is like if we selected the function Count in Designer the properties indicators. Same queries separated one for one report give correct results and together 7 queries in one report give correct results only for the first query and for others (6 others) same results for each date (if report is monthly) or the same result for each hour (if the result is daily) for all Queues tested (other which were not tested have result 0). Even the function Sum inserted into the report structure behaves weird u2013 we have the same result as in the filed (it is a copy of that result, not a sum). We tested queries together in SQL Developer and they give correct results, while in BO big query which contains script from Query 3, Query 2 and Query 1 cannot be completely executed (it executes without end).
We use Business Objects XI R2 SP3.
Thanks in advance.
Hi Peter,
I guess it is the problem due to the merged dimension and different granurality level in the BO queries. From the document properties uncheck the option of auto-merge common dimension objects or manually unmerge all the common dimensions
than give it a try.
I guess this would solve your problem. If not can you provide more query details like what objects you have used in the query.

Problems with the video/audio in my favourite web site
10.5.6 Leopard. Anybody familiar with democracynow.org? How do I know if I have a firewall? I don't think so, because I downloaded photoshop fine with wifi. I do get the video and audio from the democracy now window, but only for a few minutes, up to about 10, then the audio stops and the image freezes. They may resume if I click in the window or on the start arrow, but then they stop again, and eventually,for good.
The small screen (Real Video Stream) seems to be working, and the mp3 also. My Real Player and Real Player Downloader are sitting on the dock.
Thanks,
DonaI ran the mp3 succesfully for 50 minutes, I have about a bit more then 1/4 of the interview left, so
I restarted it and pushed it to where it stopped, this a few times, because it always stops towards the end.
I found out from "broadcast speed test" that my Download speed is 7.55 mb/s. Now what do I do with that?
Thanks,

My 4s has begun sending multiples of text messages, occasionally sending those hours or even a day later. Is this something i can fix? or is there a problem with the phone
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

Does anyone else have problems with the lightening to USB cables, particularly the longer version, when using the iPad and charging at the same time?
If so, am I doing anything wrong?Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
Someone on this forum suggested, that USB3 may interfere with the magic mouse.
I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
Thanks for the advice, Bee

What is the solution or when will be solved the problem?
Best regards
Tunk2412Dear Carolyn,
thx xo much for your support, but the problem is not solved.
Thx so much to sent me the instruction comments for the customer support, but there is always coming a message......
"You cannot reset the photostream, because there is a problem with the server connection. Please try again later."
This message is coming since 4 days.
It will be very helpful, to get a message, when Apple will be solved the problem.
Thx so much.

Problem with the cache hit ratio
Hello,
I ma having a problem with the cache hit ratio I am geting. I am sure, 100% sure, that something has got to be wrong with the cache hit ratio I am fetching!
1) I will post the code that I am using to retrieve the cache hit ratio. I've seen about a thousand different equations, all equivalent in the end.
In oracle cache hit ratio seems to be:
cache hits / cache lookups,
where cache hits <=> logica IO - physical reads
cache lookups <=> logical IO
Now some people use the session logical Reads stat, from teh view v$sysstat; others use db block gets + db consistent gets; whatever. At the end of the day its all the same, and this is what i Use:
SELECT (P1.value + P2.value - P3.value) AS CACHE_HITS, (P1.value + P2.value) AS CACHE_LOOKUPS, P4.value AS MAX_BUFFS_SIZEB
FROM v$sysstat P1, v$sysstat P2, v$sysstat P3, V$PARAMETER P4
WHERE
P1.name = 'db block gets' AND
P2.name = 'consistent gets' AND
P3.name = 'physical reads' AND
P4.name = 'sga_max_size'
2) The problem:
The cache hit ratio I am retrieving cannot be correct. In this case i was benchamarking a HUGELY inneficient query, consisting of the Union of 5 Projections over the same source table, and Oracle is configured with a relatively small SGA of 300 MB. They query plan is awful, the database will read the source database table 5 times.
And I can see in the physical data statistics of the source tablespace, that total Bytes read is aproximatly 5 times the size of the text file that I used to bulk load data into the databse.
Some of the relevant stats, wait events:
db file scattered read 1129,93 seconds
Elapsed time: 1311,9 seconds
CPU time: 179,84
SGA max Size: 314572800 Bytes
And total bytes read: 77771964416 B (aproximatly 72 Gga bytes)
the source txt loaded to the database was aprox 16 G
Number of reads was like 4.5 times the source datafile.
I would say this, given the difference between CPU time and Elapsed Time, it is clear that the query spent almost all of its time doin DB file scattered reads. How is it possible that i get the following cache hit ratio:
Cache hit Ratio: 0,92
Cache hits: 109680186
Cache lookups: 119173819
I mean only 8% of that Logical I/O corresponded to physical I/O? It is just not possible.
3) Procedure of taking stats:
Now to retrieve these stats I snapshot the system 2 times. One before the query, one after the query.
But: this is not done in a single session. In total 3 sessions are created. One session two retrieve the stats before the query, one session to run the query, a last session to snapshot after the query.
Could the problem, assuming there is one, be related to this:
"The V$SESSTAT view contains statistics on a per-session basis and is only valid for the session currently connected. When a session disconnects all statistics for the session are updated in V$SYSSTAT. The values for the statistics are cleared until the next session uses them."
What does this paragraph mean. Does it mean that the v$sysstat only shows you the stats of the last session that closed? Or does it mean thtat v$sysstat is increamented with the statistics of each v$sessionstat once a session terminates? If so, then my procedure for gathering those stats should be correct.
Can anyone help me sort out the origin of such a high cache hit ratio, with so much I/O being done?sono99 wrote:
Hi,s
first of, let me start by saying that there were many things in your post that you mentioned that I could no understand. 1. Because i am not an Oracle Expert, i use whatever RDBMS whenever i need to. 2. Because another problem has come up and, right now, i cannot inform myself to be able to comprehend it all.Well, could it be that you need to understand the database you are working on in order to comprehend it? That is why we strongly advise you to read the concepts manual first, you need to understand the architecture that Oracle uses, as well as the basic concepts of how oracle does locking and maintains read consistency. It does these different than other database engines, and some things become nonsense if looked at from the viewpoint of a single user.

It would be useful to see the execution plan jhust in case you have simplified the problem so much that a critical detail is missing.
First, the query code:

[2009-10-20 15:11:59,141 INFO]: OUTPUT_GOBLER:> 13 ;
Now, Althought it is clear from the query that the statement is executed with the NOLOGGiNG, i have disabled the logging entirely for the tablespace.There are certain rules about nologging that may not be obvious. Again, this derives from the basic Oracle architecture, and if you use the wrong definitions of things like logging, you will be led down the primrose path to confusion.
>
Futhermore, yes, the RDBMS is a test RDBMS... I have droped the database a few times... And I am constantly deleting an re-inserting data into the source database table named PROFILE.>
I also make sure do check all the datafile statistics, and for this query the amount of RedoLog, Undo "Log", Templife used is negligible, practically zero.Create table is DDL, which has implied commits before and afterwards. There is a lot going on, some of it dependent on the volume of data returned. The Oracle database writer writes things out when it feels like it, there are situations where it might just leave it in memory for a while. With nologging, Oracle may not care that you can't perform recovery if it is interrupted. So you might want to look into statspack or EM to tell you what is going on, the datafile statistics may not be all that informative for this case.

Most of the I/O is reading, a few of the I/O is writing.
My idea is not to optimize this query, it is to understand how it performs. Well, have you read the Concepts manual?
I have other implementations to test, namely I having trouble with one of them.
Furthermore, I doubt the query Plan Oracle is using actually involves tablescans (as I I'd like it to do); because in the Wait Events, most of the wait time for this query is spent doing "db file scattered read". And I think this is different from a tablescan.Please look up the definition of [db file scattered read|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/instance_tune.htm#sthref703].

Do you really have to use sessions external to the query session ? Can you query v$mystat joined to v$statname from the session itself.
No, I don't want to that!
I avoid as much as possible having the code I execute being implemented in java. Why do you think java has anything to do with this? In your session, desc v$mystat and v$statname, these are views you can look at.
When i can avoid it I don't query the database directly through JDBC, i use the RDBMS command line client, which is supposed to be very robust. Er, is that sqlplus?
So yes, I only connect to the database with JDBC... in very last session.
Of course, I Could Have put both the gather stats before query and gathers stats after query a single script: the script that would be also runing the query.
But that would cause me a number of problems, namely some of the SQL i build has to be implemented dynamically. And I don't want to be replicating the snapshoting code into every query script I make. This way I have one sql with the snapshoting scripts; and multiple scripts for running each query. I avoid code replication in this manner.Instrumentation is a large subject; dynamic sql generation is something to be avoided if possible. Remember, Oracle is written with the idea that many people are going to be sharing code and the database, so it is optimized in that way. For SQL parsing in particular, if every SQL is different, you get a performance problem called "hard parsing." You can (and generally should, and sometimes can't avoid) use bind variables so that Oracle doesn't need to hard parse every SQL. In fact, this is one of those things that applies to other engines besides Oracle. I would recommend you read Tom Kyte's books, he explains what is going on in detail, including in some places the non-Oracle viewpoint.
>
Furthermore, Since the database is not a production database, it is there so I can do my tests. I don't have to be concerned with what other sessions may be doing to my system. There are only the sessions I control.No, there are sessions Oracle controls. If you are on unix, you can easily see this, but there are ways to see it on Windows, too. In some cases, your own sessions can affect themselves.
>
then what it the array fetch size ? If the array fetch size is large enough the number of block visits would be similar to the number of physical block reads.
I don't know what the arraysize you mention is. i have not touched that parameter. So whatever it is, it's the default.You should find out! You can go to http://tahiti.oracle.com and type array fetch size into the search box. You can also go to http://asktom.oracle.com and do the same thing, with some more interesting detail.
>
By the way, I don't get the query results into my client, the query results are dumped into a target output table.
So, if the arraysize has something to do with the number of rows that Oracle is returning the client in each step... I think it doesn't matter.You may hear this phrase a lot:
"It depends."
>
As for the query plan, If i am not mistaken you can't get get query plans for queries that are: create table as select.What?
JG@TTST> explain plan for create table jjj as select * from product_master;
Explained.
JG@TTST> select count(*) from plan_table;
COUNT(*)
3
I can however commit the create table part and just call for the evalution of the Select part of the query; i believe it should be same.
"Optimizer" "Cost" "Cardinality" "Bytes" "Partition Start" "Partition Stop" "Partition Id" "ACCESS PREDICATES" "FILTER PREDICATES"
"SELECT STATEMENT" "ALL_ROWS" "2563" "586110" "15238860" "" "" "" "" ""

This query plan was taken from sql developer, exported to txt, and the PROFILE table here has only 100k tuples.
Right now I am more concerned with testing the MODEL query. Which Oracle doesn't seem to be able any more... but that is a matter for another thread.
Regarding this plan. The Union ALL seems to be more than just a binary Operator... IT seems to be Neray.
The union all on that execution plan seems to be taking as leaf tables 5 99sono.Profile tables, and be making a table scan to them all. So I'd say that the RDBMS should only scan each database block once and not 5 times.
But: It doesn't seem to be so. IT seems like what oracle is doing is scanning completly each the table, and then moving on to next select statement in the UNION ALL. Because given the amount of source table that was read, 5 times greater than the size of the source table. Oracle didn't reuse read blocks.
But this is just my feeling.Your feeling is uninteresting. Telling us what you really hope to accomplish might be more interesting.
Anyway, in terms of consistent gets, how many consistent gets should the RDBMS be doing? 5
One for each table block?It depends.

Funny problem with the mapping
Dear All,
I am facing with a funny problem with the mapping.
I am working on a scenario in which Invoice IDOC created in R/3 will be posted to XI and then in XI, mapping are done to create an XML file out of that IDOC.
In the Idoc, there is a segment E1EDKA1 which is getting created multiple times for different partners alongwith their details. The fields in E1EDKA1 segment are: PARVW,PARTN LIFNR etc.
In the output I just want LIFNR number where PARVW = RE or RS.
I have done the required mapping and when I am testing the mapping its giving me the required results correctly but when I make this scenario live then in real-time, the output XML file has no value for LIFNR.
Can anybody guide me out why is it happening tht during mapping testing its giving the correct result but at real time the mapping is returing no value.
Warm Regards,
N.JainHi Nishant,
Are you sure the test data which you are using while testing the mapping in IR and the one which comes when you test real time is the same?
The data which comes real time. Copy the source payload and then test in mapping. See if you get the right data which you expect. If you do then theres some problem.
Now also go to the same message and in trace you can find out the GUID of the mapping program which is used.
Go to RWB - Last button..not sure what the name is .. something similar to Cache.. Find your mapping program and see if the GUID Matches. If the GUID matches then it is okay.
Also try to do the following..
Reactive the MM/IM.
Go to ID. Make some dummy change in Interface determination and then activate it.
Check the cache notification to make sure if the cache is updated.
If the above doesnt help you let us know.
Regards,

Many problems with the 'Export to Text' (.txt) in CR Xi
Hi,
I have listed many problems with the 'Export to Text' (.txt) function of CR Xi.
These problems are related to this export format only (meaning everything works fine in the Viewer or in the 'Export to PDF')...
- Multi-columns layout do not export as Multi-column (export only a one column);
- Numeric values with parenthesis for negative values or with a fix currency sign at the leftmost position are not exported correctly;
- Fields having a Suppress formula which is "WhilePrintingRecords" do not appears when exported;
- Fields with 'Suppress double value' checked are not always suppressed when exported to Text.
- 'Keep Group Together' flag is not working.
- 'Reset Page Number After' simply does not works when exported to text;
- 'Keep object together' on TextBox/Section is not working.
- Whenever a group is ending on the last line of a page, the the following page as the same Group header as the previous group with no records until the page is filled, then the PageBreak and PageHeader is missing but the records of the following group appears.
I would like to know what is the status of the 'Export to Text' function (is it a deprecated function not supported anymore???).
If still supported, when will these bugs be fixed???
ThanksHi Rene
Export to Text is supported till date. Crystal Reports 2008 also supports this with Keep together working however when I tried with format with multiple columns, it didnot show up in the exported text file.

I am having a strange problem with the awesome bar
The awesome bar/location bar is no longer as awesome as it used to be. When I start typing in an address it seems like it no longer checks through my history and gives a list of possible matches but just gives the stem of an address. For example, if I type in 'goo' it will complete this to 'google.com' if I then append this with an '/a' it will complete this to 'google.com/analytics' but that's as good as it gets, as I say, no list from the history or bookmarks.
I've checked the options and also about:config and all the settings are as they should be, as far as I can tell (and I certainly hadn't changed any of them when it started misbehaving). I've also disabled all extensions and plug-ins.
It's driving my slightly bonkers because I quite often use sites with long addresses and can't remember each of the components of each address. I'd switch to using Chrome but I also use Firebug a fair bit so don't really want to do this.Hi cowtan, <br/>Sorry you are having problems with the awesome bar.
I imagine the new behaviour may be reversed by changing some pref but I have not looked that up.
Regardless of the new behaviour you seem to have some fault as my awesomebar still gives bookmarked items.
As a troubleshooting step try adding an asterisk in the awesomebar (as first character or anywhere) that should then filter the results in the dropdown list to bookmarked only items, does that work ?
* see [[Search your bookmarks, history and tabs with the Awesome Bar#w_changing-results-on-the-fly]]_changing-results-on-the-fly
You possibly have some extension interfering with the awesome bar, try Firefox in safe mode (but do NOT* at this stage try the Reset Firefox option)
<nowiki>*</nowiki>'''edit''' - personal opinion, if a user; such as you; is knowledgeable enough to use ''about.config'' the easy solution of ''FirefoxReset ''is probably not the best route, as it can have unwanted side effects that are avoidable.
* [[Troubleshoot Firefox issues using Safe Mode]]
Do your bookmarked items appear in safe mode ?
<u>Try a new Profile.</u><br/>The best method for troubleshooting this will be to set up a new Firefox profile, you can then: experiment, troubleshoot, alter settings or extensions installed in that profile without changing and potentially damaging your current profile.
* http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
I suggest to prevent unexpected problems you
* use a sensible name such as test 2012 for the profile name
* ensure an empty folder is used & do not then rename or delete the new profile (instead add or delete shortcuts to it)
* also see http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox -
Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
I have have an early 2008 imac 8,1 It has been a good machine no problems. UNTIL we downloaded Mt Lion. We can no longer use facetime. We click on the icon it comes up, tries to connect then it disappears with the message that there was a problem with the C_L Kernel Plugin. We can go on line without difficulty, everything else seems to be working. Searching the internet shows that others have had the same problem with Mt Lion. But so far I haven't found a solution. We have wiped the drive reloaded snow leopard then downloaded Mt Lion again. We put in a NEW hard drive and reloaded snow leopard then Mt Lion. We have changed out ram using apple ram. But we still get the same result. Everything works except for Facetime. Is there some patch we have missed? Facetime DOES work on our ipads without a hitch so I doubt it's the internet connection. We've tried the imac both wirelessly as the ipads run and hardwired and get no where fast. So any help at all would be appreciated. We live in the boonies, the nearest mac repair is over 150 miles away so this is pretty nuch a do it myself affair. We know the machine is old by most standards today. But we pretty much run our machines until they can't power up. So we'd like to get this one back on its perch so to speak with its face time working.
Thank you ahead of time for any advise help given.A log may help determine what the issue is ...

Is it possible to recover my data from iCloud backup without working wifi? I have as many other upgraded my iPhone 4S to iOS 7.0.2 with the result that the Wi-Fi or Bluetooth no longer works. However, i can connect to iTunes via cable but there is wrong version of backup.
Answer is no.
If you want the iCloud backup you have to have n internet connection, thus WiFi.
The not working WiFi has happened with quite a number of users.
It is not exactly clear what is the cause but there are suggestions to clear it up:
Some people have had success by removing an apostrophe from the iPhone name. If your iPhone is called something like “John’s iPhone” then this might work. Go to Settings > General > About > Name and change it to something with no apostrophe.
Some people have reported success by putting the iPhone into Airplane mode and then going to Settings > General > Reset > Reset Network Settings, but the problem may return.
You could also try going to Settings > Control Center and disable Access on Lock Screen then turn your iPhone off and on again.
Make sure that your router firmware is up to date.
Try backing up your iPhone and then restoring it. Check how to factory reset an iPhone for details.
If nothing is working for you, try contacting Apple or take your iPhone into an Apple Store.
Succes, Lex -
iTunes won't upgrade to10.5. I'm on 10.1.17.
When installing 10.5 it terminates with an error message "There is a problem with the Windows installer package. Contact the package vendor".
It does not provide an error code or details/description to further troubleshoot. As a result I can't upgrade my Apple devices to leverage the cloud.
Any smarts out there who could help?
Using PC Win-7 w/IE 7 (should that matter)
Thanks muchI know there's a million threads like this, but I thought I'd record my experience. I, too, was having the original poster's error when I tried to update iTunes on Windows XP. I think I was stuck on 10.
I solved it by un-installing iTunes and every other Apple app. I discovered that Apple Software Update would not un-install as its MSI file could not be found. I used the "Windows Install Cleanup" tool from Microsoft to remove Apple Software Update from the list of installed programs. Google "kb290301" for a Microsoft page that includes a download link for it. After that, I was able to install a fresh copy of iTunes 10.5.2.
I'm not sure why this app's folder and MSI were missing from my computer. I had once used Laplink PC Mover to move everything from my old computer to this one, and perhaps it missed a bit. -
If I click onto any link or webpage I am quite often getting a briefing 'hanging' before Mozilla responds. I also get a message at the top of my screen stating that Firefox is not responding and the loading symbol justs spins in circles until it eventually frees up and opens the page. Prior to Firefox 32.0 being downloaded on 3/9/14 I had no problems with this 'hanging' at all. I can only assume it is a Firefox issue as I do not have the same issues if I use Internet Explorer or any other programs installed on my computer.

Since the most recent Firefox update 3.6.8 my banking institution no longer shows as having a secure encrypted connection, however, my bank assures me all is well with their certificates and that is a problem with the new Firefox browser update, can you give me some idea why it is doing this?
== This happened ==
Every time Firefox opened
== Right after the new Firefox updateHello Anne.
Can you please try it in a new (temporary) Firefox profile and see if the issue is still present? See [http://support.mozilla.com/en-US/kb/Managing+profiles this article] to know how to create a new Firefox profile. Please report back the results.
