Replication problems with slow ( 20kB/s line)

Yesterday we noticed on our production database that replication did not run anymore because of an error in one record. This forced us to re-iniitalize the subscription. Maybe this is exactly what we should not have done but we did . The result was that
production stopped because of the first part of the replication to dump all the tables and make new empty ones. The problem is that this does not seem a good idea for a slow connection between 2 machines. Better would be that we could just restart the replication
from a backup but as far as I know this is not possible.
So my question is now what can we do to speed up the replication if there is no way that we can improve the line quality. (One server is in NL and the other in CN, and as everybody know there is the great big firewall in Bejing which controlls all the internet
traffic. )
Is there a way to prevent replication from emptying the tables and fill them again.
Many thanks Peter Kaldenberg

I know that probably there is a problem with our firewalls but the fact remains that we are facing with slow connections so I ques what can we do at SQL level to speed replication or better not to have to do bulk copy over the net. In-fact why does SQL not
use some kind of delta protocol. When only data is involved this should work. Of course when the layout of tables has been changed then it makes sense the tables has to be rebuild but not for data.
Maybe a solution could be to use check-sum checking and only update these records which are different and of course add the missing once.
Additional why does the replication not give information how far the bulk copy is at least then the user knows its still working. Now what ever setting I change after 10 min the replication does not give any useful information. Which results in that the
user is thinking that the replication does not work anymore.
What about 3rd party replication tools are they any better?

I had a problem with slowness so I used "reset". The popup ran forever so I stopped it. Now I can't remove or add the program.

When is Apple going to fix the problem with slow Time Machine backups with Mavericks?

I have been with Apple tech support and they got my Time Machine working by doing a spotlight re-indexing and a safe boot. This worked for about three days and I am back to very slow backups. It is impossible for Time Machine to back up every hour when it takes six hours to do the back up. I don't want to take hours to re-index with spotlight all the time. I think taking six hours to do an incremental backup is a bit much. I see that there are many people that have this trouble and it all started with an upgrade to Mavericks. The question is when is Apple going to fix this problem of slow backups with Time Machine for Mavericks. I have wasted more time than I care to. I am think of going back to Windows. I need good solid backups of my machine and Apple has taken it away with the new Mavericks. Oh, I am using the UBS 3.0 connection so the drive should not be the problem. Also this has occurred in about the last five months, so I am not sure this problem was in the original Marvericks.

Allen Thanks for your reply. All I can say is several months ago Time Machine quit working in a reasonable manner. Right now I have a Time Machine backup that has been running all night and still has three hours to go to backup 6 GB of data. I am using a OWC 1.5 TB drive connected directly to my MacBook with a USB 3.0 connection. In the resent past I have added Dropbox, GoogleDrive and a MAMP server on which I am using a program called Learning With Text from Sourceforge. There have been a lot of questions on the forum about people having very slow Time Machine back ups, so it appears to be a general problem. I should also state I am getting this very slow backup after doing the Spotlight re-indexing and the Safe Restart procedure that was told to me by apple support. I have a 750 GB drive in my MacBook Pro which I am constantly trying to keep at a 5% level of free space. This might be a problem also. However, I am working on a lot of things and like to have a lot of things on my drive. Also the heavily loaded drive has not be a problem in the past. This slow backup business started about three months ago, so something has happen in a very short time period. Now it seems even the procedure that Apple support gave me is not working. Currently I am in China and it is difficult to interact with Apple support to solve this problem, but because I am in China having my computer backed up is critical. I have run the EtreCheck and am attaching the results below. I would appreciate any suggestions. If necessary I will clear out more of my hard drive if that appears to be a solution. The Time Machine drive was recently reformed so I only have a few backups on it. I also don't run the Time Machine all the time as I don't want multi-hour backups running all the time. I run it every few days.
Here is the info from EtreCheck:

Problems with templates overtaking first line?

Has anyone else had a problem with templates taking over the first line of code in any page that a template is applied to?
I created a template that starts like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

but when that particular template is applied to a page it writes this to the code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

I don't particularly mind this, but in IE8, because the comment is the first line - and NOT the doctype, it forces the browser into another doctype and breaks the page.
Has anyone experienced this?
I've tried re-creating my templates, but I'm not finding the reason why it decides to place that comment in the beginning sometimes..

The problem may be that the comment is on the same line as the doctype, try putting a blank line between the template comment and the doctype statement
e.g.
..... IsLocked="false" -->
<!DOCTYPE HTML .....
The comment is place in the line before the doctype to enable editing of server side code, (php, asp, .net, etc.).

Problems with slow fps (or is my computer really that bad?) [solved]

I'm having quite some trouble with my fps in games like StarCraft 2 (actually it's just here that I noticed it). Anyway I've decided to test how good my computer actually is using unigine heaven benchmark.
And it's really bad. As I said I have slow fps in Starcraft in which fps is around 15, but in unigine it falls to average 4/5 depending on how I set it.
While my computer is quite old, it's still not that old, and I don't have any problem with other graphically demanding games like C&C3 or Medieval 2: Total War.
My hardware is:
System: Linux 2.6.36-ck x86_64
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ 2310MHz MMX+ 3DNow!+ SSE SSE2 SSE3 HTT
GPU: GeForce 8500 GT PCI Express 260.19.12
System memory: 2008 Mb
Video memory: 512 Mb
(this is what unigine "shows")
Also under "render" unigine shows this:

Which, while I'm no expert, for me seems quite OK.
So where's the problem?
Is my computer really that old already?
On the related note, sometimes KDE loses the window decoration or even more it just disappear. So it might be the nvidia driver (as you can see I use nvidia-beta).
But I'm not sure if it's the driver or is it the graphics card.
Thanks for any help. If nothing else you could at least tell your frame rate and hardware so I can compare if my computer is "where it supposed to be" or if something really is wrong with it.

Well I finally found the glxgears, and the fear I always feared, but didn't mentioned it in my OP came true. FPS is somewhere near the refresh rate of the monitor, and my monitor is also a TV (or should I say primary TV) so my refresh rate is 50hz or up to 60FPS. So I guess the actual and the biggest bottleneck is my monitor and not anything else. Well yeah not that my other hardware is any good, but I could say that the low FPS rate in StarCraft 2 and in Unigine Heaven is due to my bad monitor.
I can say this is solved, but not removed until I get a new monitor.
Edit: Actually there is another thing, how come that while my monitor refresh rate is 60; FPS in both Starcraft and Unigine are so much lover - instead of 60FPS there are from 4-17FPS.

Problem with slow execution on a cFP-2120

I have an application that runs on a cFP-2120, using web interface for the user to interact with the program.
I have noticed that in order to get the web interface to get updated I have to use property nodes and write to the value property, see this article:
http://digital.ni.com/public.nsf/allkb/FC5024A5DD6344C886256C8C0054689B?OpenDocument
However, this seems to give me a serious performance hit, as described here:
http://forums.ni.com/ni/board/message?board.id=170&thread.id=153531&view=by_date_ascending&page=1
I have tested with this code, and with my LV 8.2 a loop that uses 277ms to complete when writing directly to a indicator will use 203159ms when using a property node.
So, I need to update several front panel objects using the value property, but can't afford the cpu time. Does anyone have a suggestion how to do this as efficiently as possible? The problem is apparantly that using the value property requires the front panel to be loaded - can I for instance avoid doing this once for each variable?

I've changed the vi now so it only writes to value property when a value has changed. This has cut execution time in half, from 500ms to 250ms. I still think this is quite a lot...
To give you an indication of "size", the executeable is 1210kb with 2 dll's of 872 and 168kb.
I've not tried deploying a smaller (cut down?) version - what exactly do you mean?
With regards to writing to value instead of locals or directly - I've had problems with the values not updating - but not always - and the first link does suggest a bugfix. I'd like to know why wiring to value property is sometimes needed and sometimes not.

Replication problem with iPlanet directory server 5.1 SP2 HF1

If I make a apply a change to either of consumer servers for an entry that belongs to the large database, that change does get applied to the consumer targated but it can not refer the change to teh master. Neither the master, nor the other consumers get updated consequently. I did not have this problem with directory server 5.1 SP1. I only see this problem after I apply directory server 5.1 SP2 HF1.
From the error log file, I see the following message:
NSMMReplicationPlugin - repl_set_mtn_referrals: could not set referrals for replica

I have a suggestion - try another means for administering your directory - use the console only for maintenance and tuning purposes. There are several products out there that are much better for day to day operations ...
Otherwise - I think with 5.1 the view is based on the rdn of the entries - and I am not sure it is customizable. Additionally I know 5.2 solved your second issue - maybe the latest SP of 5.1 has solved it as well - though I don't really know ...

Intermittant problems with slow motion and crash of Premiere Pro

Many complain about Premiere Pro's instability.
Since a couple of days I have the same problem. Every time I want to navigate from A to B, Adobe seems to either introduce a severe SLOW MOTION effect on it's own accord, that I never put in !!!, or it just CRASHES with an error message along the lines "Problem, Try again" or similar.
This is utterly frustrating !!! I have been trying for over 6 hours today to get this remedied, but no luck.
Looking back over the past days, the problems seem to have grown exponentially both in frequency and in duration.

Problem with "carriage Return" or "Line Feed" in a table

Hello,
I need help with the function Zeichen(), so called it in german, I'm not sure if it is char() in english.
In Pages Version 4.0.1 (746) I've created a table in Pages with this function to make an "carriage Return" in a cell.
Here an example: { ="Hello" & Zeichen(10) & "World" }, in the cell is now:
| Hello |
| World |
But in Pages Version 4.0.3 (766) this function ZEICHEN() not allow the number 10 and other till 32 (I allready read the manual and understand this problem).
Anybody an idea to make a "Carriage Return" or "Line feed" in a formular, in a cell, in a table, in Pages?
Thanks
Detlev Kormann

Your workaround will not be possible in my table, because there is no empty cell in the table, but I think it is also a good help too.
*In fact I forgot that you are using a table in Pages.*
Remaining on my first idea, In Numbers we may achieve the same goal using an auxiliary table with a single cell containing the needed line break.
If this table is named "LineBreak",
the formula will be:
="Hello"&LineBreak :: $A$1&"World"
*In Pages, here is my workaround:*
Enter the cell
type a§b
don't type the character § but ctrl + return.
The cell will contain
a
b
with the arrow, move before the a
type =B2&"
delete the original a
move to the right
delete the original b
type "&C7

Problem with Sourcing for multiple line items SRM 7.0

Dear All,
We are in SRM 7.0, extended classic scenerio,
For sourcing we have selected config "Sourcing is carried out for items without a Assigned source of supply" for all sytems and all product categories
Our requirement is Catalog items should not go to sourcing, Item with and without assigned source of supply both should go to sourcing and external requirements SC should go to sourcing.
We have done coding in BADI "DOC SAVE BADI" and "BBP_SRC_DETERMINE" method DETERMINE_SOURCING.
Now we create SC with line items only using Catalog it is working fine, SC not going to sorcing,
Create SCfor line items with assigned source of supply only it is working fine, SC going to sourcing,
and Create SCfor line items without assigned source of supply only it is working fine, SC going to sourcing,
But problem is with the combination of all items i.e. Catalog, with and w/o assigned source of supply in one SC
Assigned source of supply item is not appearing in Sourcing cockpit, and some time catalog items also available for sourcing.
Please help
Thanks in Advance
Vikas

Any luck?

Hi
Please revisit your logic wriiten in this method
DETERMINE_SOURCING
Are you checking here sc has item or sc has supplier or not ( fixed supplier) in the logic? it must be item check.
As per sap standard , catalog item / fixed source of supply assigned will not venture to cockpit (Sourcing is carried out for items without a Assigned source of supply)

Problem with slow motion reversed clips

Hi
I've imported clips into iMovie 11 and can apply slow motion through Clip Adjustments. When I try to do both Slow Motion and Reverse all I get is a still clip. I tried both copying an existing Slow Motion clip and tried to reverse it and tried applying Reverse and Slow Motion at the same time to a normal clip without success. I've tried it with and without Stabilization. Any ideas?

You are not alone! But I have not found a way to resolve the problem either! Could it be a fps problem?

Performance problem with slow VIEW from JDBC (fast from SQL Developer)

Hi all,
I'm experiencing following problem and would like to know if someone else also hit this one before and has a suggestion how to solve it:
I have a pretty complicated SELECT statement that per definition returns only a few rows (~30). With no further optimization it takes ~20 seconds to return the full dataset in Oracle SQL Developer. If you add the */+ PUSH_PRED(name_of_some_inner_view) /* hint (hint is correct, stars got eaten by the OTN-forum syntax), the statement takes less than 0.5s to execute (still in SQL Developer). I saved the statement with the hint as VIEW. Selecting from the VIEW in SQL Developer is also fast.
Now if I call the statement from JDBC (Tomcat webapp), I can see from the server console that the statement is 1:1 100% the same as the one I execute in SQL Developer. Nevertheless it takes about 20 seconds to complete.
Here my details:
SELECT banner FROM v$version;
BANNER
Oracle Database 11g Express Edition Release 11.2.0.2.0 - Production
PL/SQL Release 11.2.0.2.0 - Production
CORE     11.2.0.2.0     Production
TNS for 32-bit Windows: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - Production
JDBC Driver used: some old odbc14.jar as well as current odbc6.jar for 11.2.0.2.0 from http://www.oracle.com/technetwork/da...10-090769.html
SQL Developer: current version 3.2.20.09From my reading this could go wrong:
- JDBC doesn't know the VIEW's column data types and Oracle behaves mysterious because of this (=there must be more to the SELECT than just the string, some meta-information)
- For some reason the hint inside the VIEW is not used (unlikely)
I also tried a Table Function/Pipelined table and selected from it as a workaround, but the result is the same: Selecting from Function is fast from SQL Developer, but slow from JDBC. All other statements that come from JDBC are as fast as they should be. I really don't know what to think of this and where the error might be.
Is there some setting that tells Oracle not to use hints when called from JDBC?
Thank you & Best regards,
Blama

Hi Bawer,
that's what I'm thinking. Unfortunately I can't post it, as it is library code (not my lib). But in the debug-output I can see the SQL-String sent to the DB (which does include the hint).
But I find the 2nd option you mention more likely anyway: Even if I put the hint into a VIEW and select from the view, the time-difference is there (it's even there if I use Table Functions/Pipelined table and select from the function).
So I'd think it is more likely that something else is happening (e.g. Oracle is configured in a way that it does not use hints when called from JDBC or similar. Or the library sets some session options in order to prevent the usage of hints). But I don't know if there is even the possibility of doing so.
Does the Oracle JDBC driver have the option to set these options?
Does the Oracle DB have the option to set sth. like "ALTER SESSION SET dontUseHints = 'Y';"

Problems with Scrollable Content : colored lines appear

Hello,
We have a book with several Scrollable Content (around a total of 200).
The fact is that in many colored lines appear. These lines appear i disappear when changing article,
anyone have any solution?
THANKS

Hi
I had the same problem. I had pasted the scrollable content directly into the container frame, but the pasted content was slightly 'taller' than the container window (the pasted object group was maybe 0.012 pixels larger than the container, so very slight) this caused it to display the coloured lines when I moved it up or down, although left and right movement worked fine. Resizing so the pasted content was smaller and exact pixels not 0.123 px (or the same size) as the container fixed it.

Downloading Mountain Lion - problems with slow DSL

Since we live in a rural area, my friends (who have a new iMac) are having problems downloading the Mountain Lion file.They are on the end of a DSL line feed and get a weak signal. Can I download the file on my computer and then install the file on their computer? They could log into my computer with their Apple ID to down the file. I am concerned an IP address is imbedded in the download and would cause problems. Thanks for any information.

Provided they use their account this will work. The download will finish and present a button to install, just quit at this point. Go to Applications and you will find the installer, copy it to a removable drive and then your friends can install it on their machine.
It looks like this, and it is 4.37GB in size.
