Inserts and locking

We have like 10 sessions trying to insert into a same table and we are experiencing heavy enq:TX waits (enq: TX - row lock contention). What I don't understand is why does the INSERTS have to wait for TX locks.
Can some one please clarify or provide some pointers on this.

Usually there are 2 senarios, insert could block others,
1. Waits for TX in mode 4 can also occur if a session is waiting due to potential duplicates in UNIQUE index. If two sessions try to insert the same key value thesecond session has to wait to see if an ORA-0001 should be raised or not.
2. Waits for TX in mode 4 is also possible if the session is waiting due to shared bitmap index fragment. Bitmap indexes index key values and a range of ROWIDs. Each entry in bitmap index can cover many rows in the actual table. If two sessions want to update rows covered by the same bitmap index fragment, then the second session waits for the first transaction to either COMMIT or ROLLBACK by waiting for the TX lock in mode 4

Can we use both INSERT and UPDATE at the same time in JDBC Receiver

Hi All,
I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
user send the file which contains both new and old record and I need to save those in MS SQL database.
If the record exist then use UPDATE otherwise use INSERT.
I looked on sdn but didn't find any blog which perform both the things at the same time.
Interface Requirement
FILE -
> PI -
> JDBC(INSERT & UPDATE)
I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
Thanks,

Hi ,
          If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
"If the record exist then use UPDATE otherwise use INSERT."
Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ... where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows you proceed with "insert into tablename....." since there are no old records present in database.
Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database. A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
[ This part you can ignore, Since its not sure that you will face this situation
    Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject

    There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

Not Properly Insert and Update in ODI interfaces

Dear Brothers,
The records are not inserting and updating even the CDC captured in the journal in one of my package. But, stopped and execute again then there is inserts and updates. I am not able to understand where the problem is. Can u suggest regarding the issue.

Dear Bro,
I am capturing CDC using consistent set. I am using (LKM SQL to DB2 UDB). While executing the package, the records are locked and extend window, but there is no inserts and updates into the database. It is throwing error as row index out of range while running the query. The query is running in Source Stage for ex. RTO_STAGE.JV$NUMGEN. query is triggering but records are not properly inserted and updated in the target.
First time i saw in the CDC table, there was some 10 records available while executing no insert and update. Then, i stopped it and execute it again at that time i checked in the CDC table ie., the same table, but there was only 2 records available in CDC the old records were disappeared.
I dont know the exact issue? My colleague is telling may be SNP tables not refreshing. Kindly suggest any solution.

Can I link and lock video and audio tracks - layers - as in Photoshop?

I'd like to link and lock entire clips of video and audio tracks, as I might in Photoshop, so that I can insert some material ahead of this group without having to move each separate tack in my timeline. I have a group of clips which works well together now, and it would be so nice to be able to link them, lock them together as on unit, and just insert the new material into the timeline ahead of this piece. Any ideas?

alann
What version of Premiere Elements and on what computer operating system?
For now, a generalized Premiere Elements Windows answer.....
You would select all the clips (all at one time) that you want to move together, then Clip Menu/Group.
Or right click anywhere in the selection to bring up the pop up menu including the Group option.
Have you been there and done that yet?
Please supply more information so that we can fine tune the information that you seek.
Thank you.

Crashes and Lock-ups

I have been experiencing crashes and lock-ups in Premiere CS4.
Last week I was running Encore to burn a DVD and when I noticed the processor was running flat out. I decided to run Core Temp to check the temperatures. At that point my encoding stopped and Encore locked up.
Now I usually have Core Temp start when I load Windows. I have now disabled it and when I ran Premiere last night guess what? No lock-ups. Now this is early days but I suspect Core Temp might be the problem. I hope so. I'll report back with my findings when I have had more time to experiment.
PS I'm running Windows XP SP3, Quad Core 6600 and 4Gb RAM
Cheers,
Tim

Please help! Major problems (performance and lock-ups) with brand new W520 with Intel 520 SSD

My company primarily uses HP machines but I've been a long time IBM (now Lenovo) fan so I recently had IT purchase me a new Lenovo W520 (product ID 42763LU).
Once the machine arrived I had them do the following:
Remove the 500GB HDD and replace it with an Intel 520 series 240GB SSD
Remove the optical drive and install the 500GB hard drive that came with the machine in the optical bay (with the bay adapter of course)
Format both drives and put a preconfigured windows 7 64-bit image on the SSD
A general summary of the system is the following:
Intel i7-2860QM CPU
8GB RAM
NVIDIA Quadro 1000M
Intel 520 240GB SSD (primary HDD) [SSDSC2CW240A3]
Hitachi 500GB HDD (optical bay) [HTS727550A9E365]
Intel Advanced-N 6205 network adapter
TouchChip Fingerprint Scanner
The machine was a few days delayed getting to me due to "hard drive driver issues" (that's what I was told). When I received the machine I immediately noticed that it was much slower than I expected (I have a custom built i5 HTPC at home running windows 7 on a Crucial SATA III SSD that I was comparing it to) and I was experiencing frequent hangs (ranging from 30 seconds to multiple minutes), super long boot times, general “slowness” at times, and occasional lock-ups. Since our "baseline" laptop here at work is the "equivalent" HP workstation my IT guys have been less than helpful in helping me to solve this issue. Being reasonably computer savvy I decided to try to try to fix the issue myself. I performed the following “troubleshooting” steps:
1. One of the first issues (errors) I noticed in the event viewer was errors related to the optical drive. Clearly the image they installed on the machine was not from a machine with the same hardware configuration. So, I decided to just wipe the machine and perform a fresh install of windows 7 from the disks (well, USB). After spending multiple days installing windows, performing updates, making sure all the drivers were current, and installing only the critical software I need, I was disappointed to realize that although I fixed the optical drive errors the machine was still slow, was hanging, and locking up regularly.
2. Removed the cover on the machine and removed/reinstalled the drive to verify it was secure.Everything looked good.
3. Verified the latest firmware is installed on all my Intel hardware. Everything seemed up to date.
4. I performed a number of troubleshooting steps like booting the machine with/without the battery, with/without the HDD in the optical bay, installed/removed from the docking station, etc. and none of these things helped (also a note – occasionally when running on the battery I was hearing a strange “buzz” or “static” sound coming from the area around the SSD).
5. Next I did some internet research and learned quite a few things. First, it sounds like others have had similar problems with this machine and/or SSD combo and there were quite a few options suggested to “fix” these issues. The general consensus for troubleshooting steps were:
5.1. Download and install the latest Intel chipset drivers and AHCI controller drivers (overwriting whatever windows installs during updates).This didn’t fix anything.
5.2. Turn off PCI express link state power management in the power manager. This didn’t fix anything.
5.3. Disable superfetch, prefetch, indexing, defragmentation, page file, system restore, and hibernate. A few of these were already disabled by windows so in those cases I just verified they were disabled in the services and application editor. These things may have slightly increased performance but did not fix the major hang/lockup issues I was having.
5.4. I followed online steps to edit the registry to disable the PCI link power management by adding ports, adding the required variables, and setting them all to 0. This did seem to have fixed the hangs and/or lock-ups but the machine is still much slower than I would expect (boot times are still pretty slow and it does “stutter” when I’m doing more than one thing at a time. Also a note here – I have the Intel SSD toolbox installed and I noticed that it was giving me a warning for DIPM not being optimized. I made the mistake of clicking “Tune!” and then started having the hang/lock-up issues again. I went back into the registry and sure enough the PCI link power management variables for ports 0 and 1 were set back to 1. I set them back to 0 and the hangs have gone away. I will not be “tuning” the DIPM through the Intel SSD toolbox again…
6. I also fixed a couple of other minor errors I was seeing in the event viewer by disabling benign services and/or making slight timeout modifications (I researched each issue on the internet to verify they were benign before I implemented any changes). These fixes didn't seem to do anything other than make some of the errors/warnings go away. So, the list of errors/warnings has become much smaller but I’m still getting the following (maybe an issue, maybe not?):
Event ID 37 for every processor saying that they are in a reduced performance state for xx seconds since the last report
Event ID 10002 - WLAN Extensibility Module has stopped
Event ID 4001 - WLAN AutoConfig service has successfully stopped
Event ID 27 – Intel® 82579LM Gigabit Network Connection link is disconnected
I suspect the WLAN errors have something to do with windows fighting with the Lenovo access connection tools?
7. Since the machine still seemed slow I downloaded the program AS SSD and checked the performance of the SSD. When I compared my performance numbers to the benchmark numbers I found onlineI was very surprised to discover that I’m getting about 50% of the performance that I should (values below are read/write).
Seq: 262.11 / 188.32 (s/b 504.58 / 298.28) [MB/s]
4K: 15.83 / 44.92 (s/b 21.70 / 62.60) [MB/s]
4K-64Thrd: 165.23 / 154.46 (s/b 241.38 / 234.08) [MB/s]
Acc.time: 0.218 / 0.294 (s/b .0186 / 0.208) [ms]
Score: 207 / 208 (s/b 314 / 327)
Overall Score: 533 (s/b 797)
One more note - it seems like my cooling fan is running at a high speed almost all of the time. This is probably one of my power settings (I think I have it set for max performance) but it's even doing this when there is no load (i.e. I'm using IE and just vieweing webpages - like right now).
So, I apologize for such a long post but I’ve spent countless hours researching and troubleshooting this problem and haven’t been able to figure out what the heck is wrong here. Am I missing something simple or do you guys think I have a SSD and/or problem with the machine itself? To say that any and all help would be greatly appreciated would be a massive understatement – I’m on the verge of pulling my hair out and I really need this machine working as quickly as possible!
Please let me know if you have any suggestions and/or need additional information. Thanks in advance for your help!

Lol gotcha about the drive as an option. I didn't go SSD with mine. Do you have the latest firmware on your drive? It is supposed to be v1.97. Just checking (ah and I see item 3 so guess so). Do you have the SSD drive toolbox software installed?
http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Solid+State+Drives+and+Cach...)
Seems some useful tools are in there. I can't say much beyond that with the drive. Oh. Why does your fan always run at high speed? Can you describe that? I mean, are we troubleshooting the right kind of issue? Is there anything else going on with your system? I saw about the reduced core speeds message. what are your system loads like? Anything causing high cpu utilization? Could be something other than the drive causing your low numbers and lockups.

Overheating and Lock ups with MSI TI4200 128DDR

This card seems to overheat and lock up during game play.
Does anyone have a solution?
My system:
P4 1.8Ghz 512K
Intel D845WNL
512 Mb PC133
SB Live 5.1
MSI TI4200 128DDR
WIN 98SE
300W PSU in a standard P4 case
No overclocking
Currently I play games with the case open and an external fan blowing into it.
This as fixed the problem.
I looking for a permanent solution.
Should I get a better PSU?
...or should I just get an ATI 9700 Pro

From what you said your PSU is handling the load but having a dual fan PSU will help temps by maybe a degree or two.
You may not have adequate ventilation and need to ad some fans to your case but that may be the straw that breaks the camels back if you are on the edge as far as adequate power is concerned.
There are quite a few folks that run with the side covers off but you have to keep in mind the ambient temperature where the PC is being used in any case.
So far my experience with GF4 cards is they inherently run hot and can raise the temp in your case several degrees. Nature of the beast.
Bottom line, better cooling and airflow is paramount and take a look at the heatsink, it may have been mounted poorly...this happens with any manufacturer at times and I usually re-mount it with a thermal paste of my preference. Keep in mind you will probably void your warranty with the manufacturer should you need to return or RMA the product.

Screen problems - black screen and lock-up (plus HDMI issues)

Hi, I'm not sure if these are related to the same fundamental issue, but they are both serious problems that need resolution.
I have a new mid-2012 MBPretina. I am on all the latest updates (10.8.2).
The first problem is the most recent, and the most serious problem. Since I updated the Java a couple of days ago I've been experiencing random black screens and lock-ups. Essentially, what happens is that sometimes when I perform an action (opening an app, clicking a link on a webpage, performing other kinds of in-app actions, etc.) the computer screen will go black. About half the time I can, through my own memory, try keyboard combinations to quit or force quit the most recently used app (the one where the action was just performed), and I will get some glimpse of the underlying apps, while the menubar and other areas will remain black until I move a window on top of the black space. Sometimes no key combinations work and I am forced to perform a hard restart with the power button. This is a serious issue, obviously, since I will lose current work/progress in my apps. I'm not sure if this is because of the new Java update, or has to do with something else, but it started happening shortly thereafter, over the last 2 days. I work most of my waking day on my laptop, and this "black screen of death" has happened about 5 or 6 times a day.
The second problem I have been experiencing since I starting using my MBPr with external HDMI displays in August/September. The problem is that I will plug the MBPr into an HDMI display, the screen will temporaliy go black, and then bring me to the login screen (as if it's crashing, albeit softly). This happens about 1 out of 4 times nowadays.
How can I fix these problems, especially the first?

UPDATE:
Clearly there's a problem because a third of the way through a clean reinstallation from scratch it black screened again. Hmmmm.
Now this is not good. Problem is I can't rule out potential updates from Apple that might have caused this either.
The search for solutions continues.

Hangs, severe slowness and lock-ups running Firefox 27.0 / 28.0 on Windows XP / Is it possible to block plug-in container?

Been experiencing severe slowness and lock-ups with Firefox of late, which ends with a sudden drop in memory usage and me having to repeatedly shut it down through Task Manager. I have created a new profile and disabled hardware acceleration. I have tried disabling all plug-ins and extensions, yet I noticed that at times (not always) plug-in container was still an active process, which I don't understand. Why would it be active when there are no enabled plug-ins? I also noticed that when plug-in container is not active (showing under Processes in Task Manager) I do not have this problem and Firefox runs normally? I need to block plug-in container. Please help.

I have just tried on Windows 7 and used process explorer on that. I would expect the results to be displayed in a similar manner on Windows XP.
Plugin-container is shown as being run from Firefox, and in turn if I mouse over or left click the line for plugin-container .exe then under ''command line'' it tells me what is running, in my case at this instance it is Flashplayer and so it displays
.... \Macromed\Flash\NPSWF32_12_0_0_77.dll .... plugin ....
It is identifying it is FlashPlayer
The worry with your apparently unknown operation is that within the plugin-container it may be safe but if plugin-container is disabled maybe it could be malware and cause a problem.

ODBC, bulk inserts and dynamic SQL

I am writing an application running on Windows NT 4 and using the oracle ODBC driver (8.01.05.00, that inserts many rows at a time (10000+) into an oracle 8i database.
At present, I am using a stored procedure to insert each row into the database. The stored procedure uses dynamic SQL because I can only determine the table and field names at run time.
Due to the large number of records, it tends to take a while to perform all the inserts. I have tried a number of solutions such as using batches of SQL statements (e.g. "INSERT...;INSERT...;INSERT..."), but the oracle ODBC driver only seems act on the first statement in the batch.
I have also considered using the FOR ALL statement and SQL*Loader utility.
My problem with FOR ALL is that I'm not sure it works on dynamic SQL statements and even if it did, how do I pass an array of statements to the stored procedure.
I ruled out SQL* Loader because I could not find a way to invoke it it from an ODBC statement. Secondly, it requires the spawining of a new process.
What I am really after is something similar the the SQL Server (forgive me!) BULK INSERT statement where you can simply create an input file with all the records you want to insert, and pass it along in an ODBC statement such as "BULK INSERT <filename>".
Any ideas??

Hi,
I faced this same situation years ago (Oracle 7.2!) and had the following alternatives.
1) Use a 3rd party tool such as Sagent or CA Info pump (very pricey $$$)
2) Use VisualC++ and OCI to hook into the array insert routines (there are examples of these in the Oracle Home).
3) Use SQL*Loader (the best performance, but no real control of what's happening).
I ended up using (2) and used the Rouge Wave dbtools.h++ library to speed up the development.
These days, I would also suggest you take a look at Perl on NT (www.activestate.com) and the DBlib modules at www.perl.org. I believe they will also do bulk loading.
Your problem is that your program is using Oracle ODBC, when you should be using Oracle OCI for best performance.

Missing Format Text, Insert, and Edit Source, etc Options on Some Pages

I’m having trouble understanding why certain pages have more edit options than others. I’m new to Sharepoint Workspace 2010 and I’ve been reading/ researching for answers for 2 days now. I tried to HyperSnap in some pictures however it will not allow me
to until my account is verified and it's not sending a verification email, sorry!
Issue:
On some pages, I have the edit pencil with lots of great edit options such as Format Text, Insert and Edit Source. (This is good!)
On some pages I have no edit pencil, but when I go to Page
à Edit Page à I get few edit options, not including Format Text, Insert or Edit Source. (This is not good)
After reading other somewhat similar posts, I noticed that on the pages where I get lots of edit options, they show SitePages in the URL. Where I get few edit options, SitePages is not in the URL.
Is there a fix so that I can have the expanded edit options in all of my pages? Thank you for your help!

Hi,
In SharePoint we don’t have edit page options [ribbon toolbar page edit formatting options] for all types of page for application page we cannot edit application page like site pages
again the missing edit button might be due to many causes:
Can you verify that it's not a permissions issue? Try navigating to the page in edit mode by appending to the url: your-site/Pages/YourPage.aspx?ControlMode=Edit&DisplayMode=Design
Or you can try this
your-site/Pages/YourPage.aspx? ?ToolPaneView=2
1. You can check that on some pages the ribbon is hidden by default. You need to make it visible by clicking on "Show Ribbon" on the "Site Actions" drop-down menu.
2. You haven't been doing Visual Upgrade (which actually replaces your master page with the v4.master)
3. If you have different master page and may be your master page is not 100% compatibile with SP2010, nor does it use the elements from v4.master (collaboration) or the example nightandday.master
To add the button in your page you could use the <SharePoint:PageStateActionButton id="PageStateActionButton" runat="server" Visible="false" /> (if you've seen already that would generate the button on the left side of
the ribbon)!
Please can you ping the URL of the page and how you crated that page to further assist, we would be happy to help.

Problem with unlocking and locking the Materials in MARA using idocs.

We are sending a inbound idoc from one cluster to the other to update the materials
If the material is locked ( MARA-MATFI=x ) before it needs to be unlock it ,update it and lock again .
If its not locked ,we just need to update it and lock the material .
When we are trying to implement this the materials are not getting locked at all times .
the update inbound idoc is being sent to 5 clusters at a time .
The same material is getting locked in some clusters and some it is not . (But the data is being updated in all the clusters )
Can you please suggest me a solution or give me an idea where the problem would be lying.

The client has a Keystone Server where alll the Master data is kept and there are 5 Production Servers .
When ever there are any updates to the Materials they are first updated in the Keystone server .
And with the help of a Batch Job they send inbound idocs to the 5 Production Servers.
On the Production servers if the material in MARA that needs to be updated is locked ,it needs to be unlocked updated and locked again .
Hope i have given u the clear idea of the scenario

I am trying to connect my new iMac to my Buffalo router. I forgot my router password, so I reset it and it is working. I can't figure out how to reset my router password and lock it on my iMac.

I am connecting my new iMac to my Buffalo router. I forgot my router password so I pushed the reset button and my computer was able to connect. The problem is, I can't figure out how to set my new password and lock the router. I went to the Buffalo website and downloaded the CD, as I can't find that either. I can't open any of it because it says it is Windows and can't open it. I am new to Apple!

Ah, new to routers too.
Perhaps it's best to have a local computer support person come set you up?
To explain everything would require writing a book here.
But this is what you want basically.
Router, new Wireless N, firmware updated.
1: Two accounts, one admin, one guest Internet access. Random +30 plus character lenght passwords each preferred.
(guest password to max password length of any iDevices)
2: Encryption: WPA2 AES. No Ping. No remote access. No MAC filtering. Visible.
3: Guest access on devices and computers only. Passwords written down and stored.
4: OpenDNS preferred but not mandatory.
If you get OpenDNS, you can log into their website for free and set parental controls on things like inappropriate sites for children. So whatever device is used on your network can't access a large portion of those sites (nothing is perfect) by most users who are not technical oriented.
What your doing now is running the bare bones unsecure router which can be used harmfully against you.
Even a Apple Airport router has to be very well secured. The defautl cd and out of the box setup is not a secure solution.
