Kodo do not use cache when resolving references to objects?
I noticed that if object A references object B and we read multiple A
object which reference the same B object, this B object will be re-read
from database for every fetched A object. If I read 100 A-object
referencing the same B it will do 100 selects on the same B

Was there something else about this you'd like me to comment on?_
No Abe that is it. I was not sure I am not doing something wrong. I
seemed very strange to me that internal reference resolution completely
ignore cache.
I think it is quite important - you want believe how much it slows down
object graph retrieval. It does not seem to be hard to implement. :-)_
I guess when resolving a reference you would have to use the same
validate _true/false settings as for retrieving object?

from database for every fetched A object_Yes, this seems like inefficient behavior that we should optimize. The
same B instance is returned from each relation, so it is not a bug, but
obviously it is something we could be doing a little more intelligently.
Thanks for pointing it out!

Abe,
I noticed that if object A references object B and we read multiple A
object which reference the same B object, this B object will be re-read
from database for every fetched A object. If I read 100 A-object
referencing the same B it will do 100 selects on the same B. I use
optimistic transactions with retain values = true
Could you please comment on it
Thank you very much

How do I find a previously passcode to link a wireless keyboard (Model A101urs6) to a Mac Power Book G4 running 10.5.8. The keyboard was linked at one point in the past, but then not used. When I am trying to hook it up now, it requires the passcode. Where can I find this, or is there a general number I can use?

JRE 6 not using cache in Windows 7 results in poor performance
I am using a commercial software package that uses Java. Within the company all XP users work fine and performance is great, however for all Windows 7 users the performance is appalling. After weeks of testing with the software vendor it appears that under Windows 7 JRE is not using any of the cashed images and objects and is going off to the server all the time. This can be seen in the Java trace files. This behaviour is not seen on the XP clients. The windows 7 PCs are taking about 4 times as long as the XP clients to load a page. The Java control panel program shows that the items have been succesfully cached locally on the windows 7 PCs.
We have tried...
deleting the cache
lowering windows 7 security
lowering ie9 security
even removing fonts
without any success. The vendor has now almost given up blaming a 'network policy' within our company infrastructure. Whilst I realise Windows 7 security is a lot more advanced that XP I am not aware of any network, firewall or group policies that say to Java, "Hey don't use your cache". I may be wrong.
Does anyone have any further suggestions of where to look?Hi.
Not long ago we faced with a similar problem. Our client work with oracle internet application server. Oracle iAS use jre. All was well until users work on WinXP or in Win7 thru local network, but when try to work Win7 thru VPN application began work very slow.
We try many different way, but helped us only switch off TCP AutoTuning on Win7. After that users on Win7 began work as fast as on WinXP.
How to Disable TCP AutoTuning and Receive Side Scaling
Open an elevated command prompt with administrator rights.
Type the following commands and press Enter (the second command is optional):
netsh interface tcp set global autotuninglevel=disabled
netsh interface tcp set global rss=disabled
Try this way. May be it help you too.

a brody said(http://discussions.apple.com/message.jspa?messageID=7012363) "Don't use Cache Cleaners at all except when troubleshooting."
That thread is closed so I start a new one in the hopes of getting someone, hopefully a brody, to explain exactly what harm using Cache Cleaners on a Leopard MacBook does.TTTTTTTTTTTTTTTTTTT wrote:

Depends on how you define "harm."
Strictly speaking, it doesn't hurt your Mac at all to throw out caches whenever you like.
But if there is one thing so many users like to whine about, it's performance. Why does my Mac seem slower? Why does it take so long to start up after a system update? Why is it taking so long for apps to start up? Performance is a big reason users start complaining and pointing a finger at Apple for not "optimizing" OS X.
Well guess what. Caches are one of the primary ways Apple tries to speed up your Mac. It caches all kinds of things so that once you load them into the cache it does not have to load them all from scratch. There is a startup cache for your startup items, a font cache for fonts, etc. So when you start up a Mac and it takes 45 seconds, and then you apply a system update and startup then takes 3 minutes, people think it slowed down. No, the nominal startup time is 3 minutes but it had been accelerated with startup caches all this time. Since the update invalidated the caches they have to be rebuilt from scratch.
Same thing with login times and application startups. Ever notice that the first time you start an app after a restart, it takes X seconds, but every subsequent time it takes a much shorter time (until you restart, then it's back to X seconds). That's because the app code has been cached.
So there is no technical harm to removing the caches, but it will just about guarantee that your Mac will be slower until the caches are rebuilt.
This means a user who only trashes caches when there is an actual problem to troubleshoot, and rarely restarts their Mac, should have overall faster performance than someone who dumps caches all the time and shuts down the Mac every night (since restarts trash RAM caches).
This also means that users who throw out caches more frequently than normal have to forfeit the expectation of optimal performance, since caches are so critical for that. If you are picky about performance, then obsessive cache dumping does harm your Mac. -
Not using Index when SDO_RELATE in Spatial Query is used in LEFT OUTER JOIN
I want to know for every City (Point geometry) in which Municipality (Polygon geometry) it is.
Some cities will not be covered by any municipality (as there is no data for it), so its municipality name should be blank in the result
We have 4942 cities (point geometries)
and 500 municipalities (polygon geometry)
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1
LEFT OUTER JOIN MUNICIPALITY T2 ON SDO_RELATE(T1.GEOM, T2.GEOM, 'MASK=ANYINTERACT') = 'TRUE'The explain plan for this query is:
SELECT STATEMENT
FILTER
Filter Predicates
MDSYS.SDO_RTREE_RELATE(T1.GEOM, T2.GEOM, 'mask=ANYINTERACT querytype=window ') = 'TRUE'
MERGE JOIN
TABLE ACCESS CITY FULL 11
BUFFER SORT 100605
TABLE ACCESS MUNICIPALITY FULL 20So the cost is in the BUFFER (whatever that is), it takes +2000 seconds to run this, it is not using the spatial index.
And we are not getting all rows, but only the ones interacting with a municipality, e.g. 2436 rows.
But I want all rows, including the ones not interacting with any Municipality.
When we want only those cities that actually are in a municipality, I use a different query and it will use the index.
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1, MUNICIPALITY T2
WHERE SDO_RELATE(T1.GEOM, T2.GEOM, 'MASK=ANYINTERACT') = 'TRUE'I get (only) 2436 rows (as expected) in 5 seconds (it is fast) and the explain plan shows it is using the spatial index.
But in this case, I am not getting any cities not inside any municipality (of course)
SELECT STATEMENT
NESTED LOOPS
TABLE ACCESS MUNICIPALITY FULL 22
TABLE ACCESS CITY BY INDEX ROWID 22
DOMAIN INDEX CITY_SDX 0
Access Predicates
MDSYS.SDO_RTREE_RELATE(T1.GEOM, T2.GEOM, 'mask=ANYINTERACT querytype=window ') = 'TRUE'I always thought a LEFT OUTER JOIN would return all rows from the Table, whatever happens in the next,
but it seems the query has been rewritten so that it is now using a Filter Predicate in the end, which filters those geometries having no interaction.
As an example I also do thing alphanumerically, I do get 4942 rows, including the ones which have no Municipality name.
In this case the names must match, so its only for testing if the LEFT OUTER JOIN returns stuff correctly, which it does in this case.
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1
LEFT OUTER JOIN MUNICIPALITY T2 ON T1.NAME = T2.NAMEIs this an Oracle Spatial bug, e.g. not return 4942 rows, but only 2436 rows on the first query?
Note all tests performed on Oracle 11g R2 (11.2.0.1.0)Patrick,
Even so, your geoms in the relate were the wrong way around.
Also, I don't recall you saying (or showing) that you wanted the municipality geometry returned. Still,
no matter, easy to do.
Here are some additional suggestions. I don't have your data so I have had to use some of my own.

Query not using aggregate when written against multiprovider
We have a multiprovider that contains one infocube. The infocube has aggregates defined to it. When writing a query against the infocube, an aggregate is used. However, when writting the identical query against the multiprovider, an aggegate is not used. We are running BI 7.0, Netweaver 2004s, patch set 10. Is there something that needs to be done to the multiprovider to get it to recognize the aggregate?
We have determined the issue to be one of the navigational attributes. It is not used in our query and is not in our aggregate. For some reason, the query against the multiprovider wanted it to be there. After adding it to the aggregate, we were fine. We found this using RSRT and specifying the 'Select Aggregate' option. This gave us a good message as to why the aggregate was not being used. Thanks to everyone for their suggestions.

Windows are not using dns for resolving short hostnames ?
Hello,
we are using static DNS records on our company's router and Windows is not trying to resolve hostnames.
For example on the router is set DNS foo for address
192.168.2.1
When I try ping foo from linux machine, it works just fine. But it is not working on Windows, because windows doesn't even try to resolve this kind of "short" hostnames.
It works when it's changed to foo.foo or when foo is added into hosts file. But adding it on every machine is what I don't want to do.
Is there a way how to configure Windows to resolve these short hostnames via DNS ?
ThanksThanks for your response.
Yes, windows is using router as it's only dns server. It works fine with longer hostnames (hostname has to have at least two parts). I'll try the other stuff tomorow. I'm already outside the network.
http://superuser.com/questions/480792/setting-windows-to-resolve-all-hostnames-via-dns-when-not-connected-to-a-domain
This guy has exactly the same problem, maybe he is explaining it better. Problem is that windows don't even give it a try to resolve the name through dns. Everything works fine from Linux systems. -
Safari 6 not using cached resources after restart
I am trying to debug a strange cache control issue that appears to only affect Safari 6. I have been unable to replicate it using Safari 5, or other browsers such as Chrome, Firefox and IE8. I am using Safari 6.0.3 on MacOS 10.8.3
Starting with a completely cleared cache, I make a request to a website. All the html and images etc are sucked down as normal. All images have a max age of 1 day in their cache control header.
If I then make another request to the same page, everything works as expected. It pulls down only the html file, and uses the cached images.
I then close Safari and re-open it, and make a request to the same page. This time, for some reason, it ignores the cache control directives of some of the images (seemingly randomly selected) and pulls down new versions. I have confirmed this by monitoring the apache access log of the website. I can also confirm that the images still exist in the cache (using SafariCacheExplorer), it's just that Safari decides not to use them. I've tested it on multiple websites, including apple.com.
Has anyone else experienced this? Any help would be greatly appreciated.I haven't mucked about with SafariCacheExplorer, but this is a continuing problem on my end. It's happening persistently on a forum that I run, but I've run it with other browsers on this machine and with other forum users on the same browser/OS, and I'm the one having problems. I've disabled most of my extensions, but the issue persists. It's a wee bit maddening.

Website picture sizes are not being cached when I click on their properties
Since updating to Firefox 18 on my wife's laptop when she clicks on "View image info" the size is shown as "unknown (not cached)". When I try on my desktop the Kb of pictures are showing up as normal. The only difference between the two is the desktop is 32 bit and the laptop is 64 bit.
Is the cache enabled and working on that computer if you check that on the <b>about:cache</b> page?
Also make sure that you do not run Firefox in (permanent) Private Browsing mode.

Firefox does not use cache on first load and reload
My webserver has a lot of images which will never change. So, I set Expires month forward in such cases:
Expires: Thu, 26 Jan 2012 02:01:25 GMT
Cache-control: public
Enough for IE 9, my server is not disturbed.
But for FF8 and FF9 in following two scenarios my settings are ignored:
1) Close browser. Open browser, look at about:cache - all my files are on place. Open my page - server receives requests for all cached files. And nothing in request allowing server to detect that cache exists.
2) Press Reload button or F5. Again all cached files required. But now requests have
Cache-Control: max-age=0
So, server has some idea about situation and probably can respond with 304.
Only 3) works as I proposed: after 1), open page once more - in the same or another tab. In this case, server receives only requests for files with restricted caching.
Current workaround: I add Last-Modified to response. In this case, I receive If-Modified-Since and can respond with 304. But I have hundreds of small images, so bandwidth for 304 is almost same as for 200 with complete file.
Browser cache settings - all defaults. I use numeric server addresses in current test environment like http://192.168.47.130:27374
I experimented with different modifications of Cache-Control response - without success.
And additional question - how can I make a line break in this editor? If I make a line break and empty line, I get line break and empty line. But if I make a simple line break, I get nothing in resulting text.Thank you, knorretje. Had no problems with logging on 2003. Lot of lines, but I propose that critical part<br>

I've noticed this a few times now on my home network.
When I wake my iPhone from sleep (ie. the screen is off but the phone is on) I have noticed that the 3G icon is displayed for a second before the Airport (WiFi) icon appears. Does this mean that the iPhone 3G uses only the 3G network when sleeping and it only uses the WiFi network when 'awake'?
Has anyone else noticed this?

My argument is that if you're connected to your home network it would be *reasonable to assume* that ALL data is coming via your own network. There is nothing in the manual that would suggest otherwise. It should at least keep WiFi on if the iPhone is plugged in and charging.

Personally i don't care about other people's plans. Only my own. If it's not very useful, then stop asking stupid questions about when your not even using the phone. -
My ipod touch only charges when its not in use and doesn't come up with the charging symbol. Please help cheers
First try another charging source. Maybe the source yo are using is not putting out enough pwere when the screen is on.
Next try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device. -
Can not use message when phone is horizontal
When i want to use message and i turn the phone horizontal the screen turns off as soon as I start typing. This only happens in message. I can be using the internet and works just fine when i am typing.
There is no issues when i leave the phone vertical and use message.
Is there anything i can do to fix this issue?
I have an iphone 4sTry this first:
Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)
