Is DB_THREAD needed during db_env_create for multi-process db access?

Using BDB as a transaction data store, where mutliple processes can read/modify the data. NOT creating any threads within any of the processes. Do I need to set the DB_THREAD flag during db_env_create ?

Hi Kedar,
Only the DB_ENV and DB handles are free-threaded if the DB_THREAD flag is used when opening these handles.
You should specify DB_THREAD only if you intend to use the handles in more than one thread in a process. If only a single thread per process will be used there is no need to specify the DB_THREAD flag.

Andrei

Configuring the DbEnv for multi-process single-writer scenario

I have (1) a multi-process server program (Apache/PHP) using the XML container read-only and (2) a couple of scripts (Perl, PHP, whatever), one of which may be performing update work on the data at any given moment. There is, however, no concurrent write access.
Write access, if I've understood correctly, commands the use of transactions in a multi-process scenario. Specifically, I'd use:
* DB_INIT_MPOOL, DB_INIT_LOCK, DB_INIT_LOG and DB_INIT_TXN when creating the environment, so that all subsystems that will eventually be needed are in place;
* DB_INIT_MPOOL, DB_INIT_LOCK, DB_INIT_LOG and DB_INIT_TXN for writing;
* DB_INIT_MPOOL for reading.
Please correct me if these assumptions are somehow flawed or simply wrong.
Do I need more flags?
Now, in the Berkeley DB Reference Guide, I read about Berkeley DB Concurrent Data Store Applications and the DB_INIT_CDB flag. I wonder if (a) this information also pertains to BDB XML and (b) this fits my scenario - only one write process at any given time.
If I can use DB_INIT_CDB, what will I gain with respect to the scenario laid out above, or any other possible scenario?
Michael Ludwig

Hi John,
thanks for pointing out that the flags used to open the environment have to be consistent among all applications.
As for CDB:
CDB puts a single big lock around the database, and
won't let any readers get access to anything while a
writer is operating. Generally it is advisable to use
transactions in preference to CDB, which will allow
concurrent reads and writes. You should also consider
using MVCC, to increase concurrency more.Thanks for this info on MVCC. I remember reading an interview with the Interbase (then Groton Database) developer Jim Starkey, who seems to have invented MVCC, in which he told how, one morning in the shower, it appeared to him that multi-version concurrency control was the solution to almost all problems. Well, database problems, maybe.
I read about MVCC in your Transaction Guide.
http://www.oracle.com/technology/documentation/berkeley-db/xml/gsg_xml_txn/cxx/isolation.html#snapshot_isolation
"What [MVCC] means is that every time
a writer would take a read lock on a page,
instead a copy of the page is made and
the writer operates on that page copy.
This frees other writers from blocking
due to a read lock held on the page."
I think an application featuring high concurrency of read and write operation will benefit from MVCC, provided there is enough memory to accomomate all the page copies. And I will eventually need this.
At the moment, however, the update is done using the typical nightly crontabbed batch job. Not much traffic expected during the update, and no updates while the site is busy. I doubt I have much to gain from MVCC in this primitive scenario. What do you think? Would I still benefit from MVCC, or would I only incur the copy overhead without benefitting from it for lack of read-write concurrency?
Michael

Create child concurrent program for multi-processing

Hi,
I have a requirement where in I need my main concurrent program to generate child concurrent programs to process data in parallel.
I want all the child programs to write the response in the output file of the main concurrent programs.
Any pointers to this will be a real help.
Thanks.
Jujaar

Hey Sandeep,
Thanks for your response...
OK, even I was thinking on those kind of solution or other possible way is to directly write in the output/log file of the parent req.
Cause the output file is always formed at a loction with a std. naming convention o+request_id.out.
I think it might be possible to write directly into the file. Have not tried it yet.
And one more question, do you have an idea how to generate the child concurrent programs.
I do see a parameter names sub_request in fnd_request.submit_request package. This is a boolean type.
But I am kind of unsure, If I pass this parameter as TRUE, how it will find the parent request ID.
If you some information on this as to how we can submit child concurrent request, please share. IT would be a great help.
Thanks

Functions for multi-phase catalog access, with retries...

See Catalog:action & Catalog:privateAction below.
These functions support iterative catalog access, to divide catalog updates into chunks...
Also, they support retries to deal with contention in case another plugin task is already accessing the catalog.
-- private method:
function Catalog:_isAccessContention( qual )
 local found = qual:find( "LrCatalog:with", 1, true ) or 0 -- return position or zero, instead of position or nil.
 if found == 1 then -- problem reported by with-catalog-do method.
 local found2 = qual:find( "already inside", 15, true )
 if found2 == nil then
 found2 = qual:find( "was blocked", 15, true ) -- Lr4b
 end
 if found2 then
 -- problem is due to catalog access contention.
 Debug.logn( 'catalog contention:', str:to( qual ) )
 return true
 else
 return false
 end
 else
 return false
 end
end
-- private method:
function Catalog:_action( catFunc, tmo, name, func, ... )
 local t = { ... }
 local tries = math.max( math.ceil( tmo * 2 ), 1 )
 local sts, msg
 local function _func( context )
 sts, msg = func( unpack( t ) )
 end
 local count = 10000000 -- ten million max, for sanity.
 repeat
 local s, other
 if name then
 s, other = LrTasks.pcall( catFunc, catalog, name, _func )
 else
 s, other = LrTasks.pcall( catFunc, catalog, _func )
 end
 if s then -- no error thrown
 if sts then
 return true -- all done.
 elseif str:is( msg ) then
 return false, "Unable to complete catalog update - " .. msg
 else
 -- continue
 count = count - 1
 end
 else
 if self:_isAccessContention( other ) then
 tries = tries - 1
 if tries == 0 then
 return nil, "Unable to access catalog for " .. str:to( tmo ) .. " seconds."
 else
 LrTasks.sleep( math.random( .1, 1 ) ) -- sleep for half second, plus or minus.
 end
 else
 return nil, "Catalog access function error: " .. str:to( other )
 end
 end
 until count == 0
 return nil, "Program failure"
end
--- Wrapper for named/undoable catalog:withWriteAccessDo method - divide to conquor func.

-- @param name (string) undo title.
-- @param func (function) divided catalog writing function: returns sts, msg = true when done; false if to be continued; nil, error message if trouble.

Note: These functions were changed a bit after further testing and integration - consider them for example purposes only. The released version of these functions will be available shortly as part of the Elare Plugin Framework:
https://www.assembla.com/spaces/lrdevplugin/
PS - After some mods, the final version allows me to write code like this which I find convenient (still not released yet at assembla.com):
local coll
local s, m = cat:update( 10, "Assure Folder Collection", function( context, phase )
 if phase == 1 then
 coll = catalog:createCollection( folder:getName(), parent, true )
 return false -- keep going.
 elseif phase == 2 then
 coll:removeAllPhotos()
 return false -- keep going.
 elseif phase == 3 then
 coll:addPhotos( folder:getPhotos() )
 return true -- done (same as returning nil).
 else
 app:error( "bad phase" )
 end
end )
if s then
 app:logVerbose( "Assured collection: ^1", coll:getName() )
 return coll
else
 return nil, m
end
or
local photos = catalog:getAllPhotos()
local s, m = cat:update( 10, "Update Photos", function( context, phase )
 local i1 = (phase - 1) * 1000 + 1
 local i2 = math.min( phase * 1000, #photos )
 for i = i1, i2 do
 local photo = photos[i]
 -- do something with photo that writes catalog.
 end
 if i2 < #photos then
 return false -- keep going
 end
end )
if s then
 app:logVerbose( "Photos updated..." )
 return true
else
 return false, m
end

Hi Vladimir,
You can see the outside & inside of DevMeta for complete details, but in a nutshell , there are few things the "background" task does, including:
1. Check if the develop settings of the currently viewed photo have changed, if so update metadata for the library panel view (and Library Filter, and Smart Collections...) - this is what I call: Auto-Update.
2. Check if user has edited the metadata - in which case it updates the develop settings of the active photo (called Live-Edit).
The posted function makes sure none of my other plugins complain if they can't get at the catalog while DevMeta has it (which usually does not happen, but sometimes does). However, other peoples plugins will occasionally fail if they assume the catalog to be free for them all the time (and they have DevMeta running). There is at least one other fellow doing something similar, so I'm not the only plugin developer with the "bright idea" of doing things in the background that require catalog access.

Need a Userexit for ME51N, ME52N to access data in Account Assignment Tab

Hi,
I am currently using Enhancement MEREQ001, EXIT_SAPLMEREQ_005 to check line item data and display an error message.   That works fine.   My need now is to access the Order Number entered under the Account Assignment tab.
The import parameter IM_DATA_NEW does not contain this info.   Can anyone please let me know if there is an exit that can be used to access the order number from the screen?
Thank-you,
Priscilla LeMay

First of All, you have to get the information about item, so yo have to call the next method:
DATA: lv_acc_list TYPE mmpur_accounting_list.
CALL METHOD im_req_item->if_acct_container_mm~get_items
      RECEIVING
        re_items = lv_acc_list.
Secondly you must do loop to this table, and call another method for get the information about Account Assigment:
data: lv_model TYPE REF TO if_accounting_model_mm,
   LOOP AT lv_acc_list INTO ls_acc.
      lv_model = ls_acc-model.
      CALL METHOD lv_model->get_exkn
        RECEIVING
          re_exkn = lv_exkn.
In variable lv_exkn you have the values.
I hope it runs ok.

Script for batch processing

Hello
I need help
I created a batch sequence which set watermark and security to pdf files from one directory. Now i want to create another sequence: 1. set security to none and 2. delete watermark.
I have a problem with set security to none because every time i need change preferences for batch process to security method=password security by hand.
Maybe there is a way to change this settings with java script in batch "execute java script"?
Or how i can change with batch sequence a security method from passsword security to "none" if i know password
Thanks in advance

Create a "blank" batch process (ie, without any action), but under the Output Options tick the box to optimize the files and set the optimization settings you want to use.

How do I format a DVD copy for multi-zone or Zone 1?

How do I format a DVD copy for multi-zone or Zone 1?
Final Cut Pro X version 10.1.3
I have to send a DVD copy to a festival. They need it formatted for multi-zone or for Zone 1 (North America). How can I make sure it's formatted like that?

I don't claim direct experience with that, but I *believe* (as in "I could be wrong, but") that if you burn a DVD from inside FCP X, the program will take a clue from the frame rate of your project: a 25fps project will produce a PAL DVD, a 29.97 will do NTSC.

Project Server 2010 Resource Assigments - Need a license for every Resource?

I am trying to determine the requirements for Project Server 2010 licenses.
In Project Server 2010, I need to add resources to the pool, then assign a resource to a project task. The task will be maintained/statused through a manager, not the resource.
Does that resource need to have a Project Server license even if the resource never accesses Project Server even through PWA?

Hi JenKranich,
You need licences only for users that will access
Project Server data by any means :
MS Project Pro, Sharepoint sites and/or
PWA.
But resources not associated with users are not "real person" accessing data but just informal entity, thus no need for licences for those resources.
It is important to note that if those resources can access the SharePoint site, since it contains Project Server data (risks, issues, deliverables), then they DO need a licence.
Hope this helps.

TS2180 Need a resolution for multiplexor error during burns?

Need a solution for Multiplexor Errors during iDVD disc burning process?

Hi
Multiplexing error is a very complex problem due to many things (long long list following) - one common but not obvious reason is that material on the iDVD menu goes outside the TV-Safe area (or just touching it).
So first - turn on TV-Safe area and move any object well inside of this.
Wide screen stretched - usually (as I think) it is due to making a 4x3 movie in a 16x9 wide-screen project OR the other way around. This forces one to on flat-screen TV (or other) set the presenting view right - My has 4x3, wide-screen, zoom and auto-wide-screen and I have to switch this by my remote for some DVD I've made "wrong" way.
Now my long long list on Multiplex Error
LONG LONG LONG LIST
Multiplexing Error
PART One.
Use of strange video/audio material e.g. .avi, .wmv, .mp3 etc.
I only use.
Video - StreamingDV (miniDV tape via FireWire) and
Audio - .aiff (as on audio-CDs) (else converted to this .aiff 48KHz)
Photo - .jpg (.bmp known problematic)
Chapters !
A. Using strange letters in video project name e.g. +,/; etc. keep to a-z and 0-9 strange letters in project name e.g. +
as described by Donnyboy69. Does the title of your project have any symbols or decimal points in it. If so, that is why you are getting the error. I had a project that had a + sign which caused the same problem. I renamed it without the symbol and low and behold, it worked.
B. Location of Chapters
• Can’t be at start or end of movie (Skip first/start one - iDVD sets this by it self. At the End - no need)
• Not in a transition (or within 2-3 seconds from it)
Important when from iMovie HD6 or previous - Now also observed when using FCE 4
PART Two.
from Robert Modero.
"Multiplexing Error. Problem during initialization of tracks"
Simply remember to add subtitles to your Quicktime files and menu buttons.
Once I did that, I was back in business.
from Boise Jim
Do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
I always makes a DiskImage first and test this so that it runs OK
I use only - Verbatim DVDs
I use only - DVD-R
I burn at an as slow speed possibly e.g. x1
This gives good DVDs
PART Three.
Multiplex Error
Chuck, Chicago 2/7/2009.
Back again. Here is what I have found to work. I also have and use a LaCie DVD-R/RW DL external drive and a LaCie external hard drive as well. Since yesterday I have tried a few ways to burn a themed iDVD project having four 56 minute movies on it, amounting to 226 minutes onto a DVD DL disc, capacity 240 minutes. Apple tech support really didn't know what to do but gave me a very good tip. I had two options left. Apple tech support's tip was to try disc image. One of the replies on a thread with this subject said not to, but my experience today is good. Put your project onto "Burn to disc image," under "iDVD, file." Yesterday encoding took me 23 1/2 hours. Overnight for iDVD disc image, encoding took 21 1/2 hours (again) while I slept. This morning I tried to copy/burn disc image to a DVD with Roxio Toast 7, and it stopped near the end of the burn with some kind of "error" message. So then I tried Utilities> Disc Utility> Burn icon, and followed it through. Be sure to click the DVD DL drive in the window "Burn disc in.". I had one other problem though. At the end of a 46 minute copy, it started to verify, and at the end of verify it rejected the burn. So I tried again, and when "verify" appeared, I clicked on "Skip." The disc finished burning and is doing fine and well. A long and tortuous process, but at last something works. I made several additional copies using Disc Utility. Best wishes. Chuck, Chicago.
2. Disconnect any other external devices not absolutely needed.
e.g. external USB/USB2 hard disks, other FW hard disks etc.
3 Chapter marks in transitions - minimum 2 sec from
FROM Bev. (Not a 'guy' but I will answer!)
First, I do not think that mixing wide-screen and standard makes a difference in iDVD.
Second, you should use a better brand of DVD disk. Also, many of us have experienced fewer problems on playback with DVD-R disks. Recommended brands here are Verbatim, Maxell and Taiyo Yuden. Memorex and TDK are not consistent and may not give you a correct burn. They apparently have fewer layers in the composition of the disk. I have always used Verbatim DVD-R disks and have not had any burn problems.
Also, choose a slower burn speed, 4x or less.
Third, to determine if the iDVD project will burn properly, create a disk image file (from within iDVD, go File->Save as Disk Image) and test it. Mount the disk image and then open DVD Player (in Applications) and view your project. If it plays correctly, you can then burn the actual DVD disk from the disk image file using Disk Utility.
From. Boise, Idaho
I did everything I've seen suggested, but a friend (who used to be an Apple Genius) suggested that I do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
It worked, and I got a clean burn from iDVD.
Hopefully this can help other people.
by dheb0422
Well, I finally got it, and it was odd enough to post here incase anyone looks this topic up again. Many things were tried, including burning the unedited film, the edited film without titles and chapter markers, abbreviating the chapter markers in case length was the issue (remember the old iMovie used to truncate them when moving to iDVD?). In the process, I noticed that one, and only one, chapter marker was on the same line as the title marker. All the others were on the line above. The only way I seemed able to change that was to clip a few seconds of film. After that last clip, the offending marker took a place on the line above, as were all the others. That run published, compiled completely and burned. That's one for the books.
One user more writes
To add my experience with Multiplex Errors using iDVD (7.0.4), I recently created two iDVD projects
Video from both passed from FCE 4.01 with chapters
One project worked fine in creating disk image file
The other gave Multiplex Errors
I tried suggestions to remove special characters and no chapter marks at beginning, but nothing worked
Note that I've used iDVD for dozens of projects and this is first time I've run into Multiplex Errors
Anyway, for problem project, I tried an experiment where I removed all chapters in FCE and passed to new iDVD project
This time multiplex errors gone
So had something to do with chapters
So now I tried numerous experiments to remove individual chapters and try again creating disk image with new iDVD project
After numerous tries, I was able to narrow problem down to 1 "Bad" chapter mark
That is, when I left the "bad" chapter in my FCE project and passed to iDVD, iDVD gave multiplex error
When I removed "bad" chapter mark (and others in), no multiplex error
As a final experiment, I moved "bad" chapter mark about 5-10 sec's beyond original point and passed to iDVD, the multiplex errors now magically went away and I was able to finally create my disk image.
I have no idea why this worked, but thought I'd mention here in case someone else runs into similar problem.
Rich839
In addition to Bengt's fine advice, burning errors can occur if you have located any of your menu buttons wholly or partly outside of the safe TV viewing area. Go to your main project menu, then click on View/Show TV Safe Area, to check. Drag into the safe viewing area any buttons that are outside the safe viewing area.
Russ One - suggest this
Multiplex Error-There was an error during muxing preparation
One thing that worked for me was to export the video w/o chapter markers as a self contained movie (thereby not loosing the edits & etc). Then make a new FCE project and import that movie into a new sequence and add the chapter markers. I've used "-", "&" and "," with no problem in the chapter names. Removing the markers or exporting without them did solve the problem but renaming them with just numbers 1,2,3....5, did not solve the problem and since this problem seems to happen with with iMovie as well, it would suggest the problem is in the video or audio and in combination with the chapter markers iDVD just can't handle it. The only other possibility is that both iMovie and FCE share the same or similar chapter marker code that some how is corrupting the markers.
Summary - What to try
1. Chapters
• Only A to Z and 0 to 9 in chapter title
• No Chapter mark at very beginning of movie
• No Chapter mark in or within 2 seconds from any transition in movie
2. TV-safe area for buttons (no one outside this)
3. Safe re-boot
4. No other external devices connected - that are not needed
SDMacuser adds to this
• On #4 ... No ext. devices. Some think this applies mainly to ext. FW. Not the case. Also applies to ext. USB2 as well (not to mention flash drives too).
Do not leave 3rd party devices / camera / camcorder plugged in unless it is being used with iDvd's One Step process. Certain web cams can trigger this also (especially ones with added features like LED light/s that draw additional power from the FW or USB bus).
5. Minimum of 25Gb free space on Start-up hard disk
6. Make a DiskImage first - reduces where problem originates
7. Trash iDVD pref. file
8. Make a new iDVD project
9. Movies in project with same aspect ratio e.g. 4x3 or 16x9
10. No other programs/applications running during iDVD process. e.g. Internet, screen & energy savers

Help needed for file processing using FTP

Hi All,
I am new to ODI tool and currently we are implementing one project in ODI. Could you please, any one help me on the following requirement... how to implement it?
Scenario:
i) I need to pick a file from remote host 'outbox' dir using FTP process, and place into local 'temp' dir. (I can do it with odiFTPGet tool)
ii) Change the file as per target business requirement.??? ( this step challenging me)
for ex:
if source file name : <project name>_<source ID>_<transaction name>_<unique id>.txt
target name should be : 1234_<transaction name>_<sysdate in yyyyMMddhhmmss>_<unique id>_2345.txt ( here 1234 and 2345 are hard coded values)
iii) Later move to local 'temp' to local 'outbox' dir. ( I can do it with odiFileMove tool)
iv) After successful process move the file from remote 'outbox' to remote 'archive' dir ??? (again this is challenging me).
For this my questions are:
1) How to get file name into a variable ( In one of the post , it says we need to create data model and data stores, and interface to get the file names into a file. apart from is there any easy way i can implement it in package it self?)
2) How to tokenize a long string ( i.e., need to tokenize the source file to get <unique id> and <transaction name> and map to target file name)
3) How to define implementation for Java in user function?? do we need to use class declarations and import statements?? I need a sample user function in Java.
4) How to move/rename a file in remote server?? ( need to move file from remote 'outbox' server to remote archive' dir)
5) If any step in package fails, How to get the error msg into a variable which i can use for sending mail and raise a ticket in remedy?? ( I will pass that variable to as content to mail and remedy ticket)
6) How to handle list type data (string list) by variables in ODI?? (As we can define single variable not as list.)
I am sorry to ask all my queries I a single post. But I need to solutions for all to implement this in my project.
Thanks in advance. Appreciate early response.

I am able to get color images in the continues shot but when i try to snap a color image which i need for my processing i get only a monocrome image

I have been using lv_vfw.llb VI's for grabbing images from a CREATIVE WEB CAM ,i am able to get color images in the continues shot but when i try to snap a color image which i need for my processing i get only a monocrome image ,i have been trying to play around with the RGB weightings but i am unable to get a color iamge,it shall be of great help if you could help me in doing this as it is urgent for me.Thanks for your help.

vicky,
I am unfamiliar with the lv_vfw.llb, and have not used it before. However, I noticed that you stated that you are able to grab in color, just not snap in color. If this is the case, why not just perform a grab and then extract a single buffer from this grabbed data, which would likely be in color? This seems like a possible solution to the issue that you are seeing.
Other than that, I really don't know enough about the lv_vfw.llb to be of much help on this issue. Hopefully another member of this forum will be able to assist you with this software.
