How many cross-project links are too many for dynamic Master-Subproject plan?
Hello
We currently have a dynamic master-subproject plan and resource pool, with 8 workstream plans and approximately 150 program milestones in the master. We are considering creating cross-project links to the 150 program milestones - from the master
into the sub-projects. I have read that it is best practice to keep cross-project links to a minimum. Is what we are considering too much? Will 150 links from master to sub-projects risk a corrupted plan?
Thanks in advance...

Yes the cross-project links also use old DDE technology which is where the file corruption risk is. Move, rename, overwrite or store on a WAN and the file corruption dice roll. Its when not if, but you can be lucky and survive many months.
What do I do? If Project Online/Server and its deliverables feature is not available then being a bit of a VBA whiz:
I copy all milestones weekly to SQL Server using a VBA macro.
In other projects I have a macro to select one of those milestones and record teh project number, title and task unique id into a text field.
I then have a macro that finds all tasks with data from step 2 and reads the latest date from SQL Server and updates the task start date.
This works perfectly and has zero corruption risk as the only thing I store is text data in a custom field. I've supported some large SAP programmes with 10 files and many thousands of tasks using this technique. Oh, yet another macro creates static (so
no links) masters each week for reporting purposes from all sub-projects.
Art, with the number of files and links it might be time to experiment with Project Online.

How many photos are too many photos for iPhoto? When do I need to upgrade to Aperture?
How many photos are too many photos for iPhoto? When do I need to updgrade to Aperture?
Hi Terrence, this is what happens, all too often when I click on something, sometimes it takes me 5 more clicks on the mouse while moving the cursor around to get rid of it. The one below popped up as I clicked on my junk mail.
The next one popped up when I was trying to get on to a site. This happens all the time. Don't know why it is happening. It happens on iPhoto, Aperture, everywhere I go, FaceBook...everywhere and at any time. So frustrating. I don't know if this is normal, but this was happening just before my last mac died a year ago. -
There are too many levels of symbolic links to translate a path name.
Hi
I am copying from our TEST to DEV system, the command being this
cp -r /oracli2/oracle/testora/iAS .
However, the following messages were returned during the process
cp: java There are too many levels of symbolic links to translate a path name.
I checked and there indeed are many symbolic links.
I have checked ML for this and no luck.
Any one have an idea??
Thank you,
DA
Told to tar the files, working on that now.
Edited by: Dan A on Sep 18, 2008 12:11 PMHussein what a marvelous suggestion.
That by using cp -RPI can avoid doing a tar ...
I am copying the applciation directories from TEST to DEV.
I have copied the iAS directory from TEST to DEV using the tar (appcldev user)
Now with the appdbdev user, I try to do the same and I get an error with tar:
tar: 0511-169 A directory checksum error on media
After checking for the solutions and fining nothing that could help me, I am now simpy copying using the cp -RP.
Now I have (i know this is a UNIX thing) on the target system:
iAS directory that was copied using tar (for appcldev user)
iAS directory where symbolic links were preserved (for appdbdev user)
Is this difference acceptable vis a vis cloning? Or should I go back to the appcldev user and recopy the iAS directory with the cp _RP option?
Thanks again. -
Flatten a Key Value Pair...how many joins are too many?
Hello,
So, a product can have many attributes...things that describe the product. In our 3rd party ERP, these are stored in a key-value manner.
product_code
attribute_code
attribute_value
etc.
Now, for some products there are 150+ attributes....you can pretty much guess where this is going...
User wants a report that shows an product_code and it's attributes on a single line (in separate columns) for Excel manipulation(s).
So, the SQL would require joining the same attribute table as many times as there are distinct attribute_codes for a given product_code.
If there are 150 named/distinct attributes that need to be lined up, this would mean 150 joins on that one table.
OR write scalars for each attribute
OR write a function that fetches the attribute_value when you pass the product_code and attribute_code and call this function 150 times in the SQL select list.
Yes, I know, I should benchmark each approach and select the one that works best....BUT, I would like to poll the wisdom of outstanding individuals on this group to see which of the 3 approaches would be preferred.
Oh and the users typically "query" hundreds to thousands of products and want this result set.
We are still on the terminally supported Oracle 10g database on Linux.
Thanks,

I like to have instant access to all my bookmarks as I keep my RSS links and current projects up there. When there are too many to fit in one row across the screen firefox makes a little pull down menu at the end with all the rest in. I find this really annoying, its just the same as the normal bookmarks menu; I find it really hard to keep things organised when I can't see them all the time. I would like it to make a second or even third row in the tool bar so I can always see all my current RSS and Pages. Can I do this? If it wont work on firefox does anyone know of another FS, OS or FOSS browser that will?
Unfortunately, the extension does not work with Firefox 4, and Alice have no intentions to upgrade it.

There are too many PIN changes associated with this account (Error ID: 30801)
how to solve this error on app world "There are too many PIN changes associated with this account (Error ID: 30801)" can anyone advice because I follow all the steps to solve it and no one answer me
I call the customer care using the free number then I call my provider to redirect me to blackberry customer care and no one help me
so is there any link can show me all the PIN which is assign to my account and manage them
Please AdviceHi and Welcome to the Community!
Here is a KB that discusses that error:
KB25553 "There are too many PIN changes associated with this account (Error ID: 30801)" is encountered when attempting to login to BlackBerry App World
As you see, the way to resolve it is clear, and you seem to have reached some folks in your attempts that were not able to resolve it. Nevertheless, you should not allow them to fob you off...insist that the KB instructs the resolution path and insist that they make good on that.

I saved a file last night and now this morning I get an error message stating: "Photoshop CS5.1 Extended: Could not complete your request because there are too many Files Open. Try closing some windows and try again.". I've rebooted the system and made sure Photoshop was the only program running and that there were no other files open prior to trying to open my file. I increased Photoshops ram usage, checked the OpenGL settings, 3D and VRAM settings, cleared my temp files and am at a loss for opening this file.
System Specs:
Win 7 64
6 core I7 processor
32gb Ram
3GB VRAM
600gb free space on 7200 rpm drive
File specs:
1 3D object replicated maybe 5 times (yes, I should have rasterized them, and will do that to 4 of them if I get the file open)
Maybe 8 textures
Not sure how many total layers.
Is there anyway to get Photoshop to reopen this file?No, more VRAM is useless. I had the same thought as you so I tried with a friend's computer with 3GB of VRAM for 8GB RAM (mine has 1GB VRAM for 16GB RAM). Still got the same error message. Sorry guys but our files are lost until Adobe fix the error in Photoshop code. I hope in the future they will find a way to either fix this error or give a clear limitation, it is really a shame such a dangerous problem exists and persists for more than 3 photoshop gen.
Still you may be able to have at least a flat image of your latest file by trying to open the file as smart object. I started my work over by doing that. Not a lot but better than nothing.
However for my new file I am trying something different : Each time I think a 3D file is final, I do not rasterize it but make it into a smart object and save the new smart object into a single separated .psd file. If any change is needed I can still edit all of my 3D objects by opening them separately. So far it works, the global file is lighter with few to no 3D objects inside but I will not say it is a 100% no-risk method yet.
Last advice I can give everyone : Before closing the file you are working on, save it as a copy (File / Save as... and check 'As copy' in the options below) then with your main file still open, try to open the copy. You may need a lot of memory if your file is heavy but still if the dreaded error message appears when you try to open the copy then remove or rasterize some 3D objects in your main one. Save again as copy and try to open the copy until you do not get the message anymore. -
There are too many TREX Errors
Hello Experts,
I have created an Index for a specific folder in KM.
Under KM--> Sys Conf --> KM --> Index Administration it shows the green led, which I believe that the data sources are completely indexed. But, under the KM--> Monitoring > KM> Indexing Monitor , it says:
Status = red led (There are too many TREX errors)
Status = Active
In Process = 142678
Indexed = 51345
Errors = 10849
And, when I opened the list of errors there are many Crawler and Trex: Preparation failed: index operation
Can you suggest, what's the mistake that I am doing or do I have to any additional configurations for the index that I have created??
Thanks,
RaghavaHi Raghava,
as I said, "Preparation Failed" may be (if I recall correctly) as early as the HTTP request to even get the document for indexing. If this is not possible for TREX, then of course the indexing fails.
What I suggested was a manual reproduction. So log on to the TREX host (preferrably with the user that TREX uses to access the documents) and then simply try to open one of the docs with the "failed" status by pasting its address in the browser. If this does not work, you have a pretty good idea what's happening.
Unfortunately, if that were the case, this would the be some issue in network communications or ticketing and authorizatuions, which I can not tell you from here how to solve.
In any case, I would advise to open a support message to SAP - probably rather under the portal component than under TREX, as I do not assume that this stage of a queue error has anything to do with the actual engine.
Best,

Cannot create a calendar collection because there are too many already present in
My OS X Server (Yosemite) error log is throwing this error:
2014-10-22 00:03:07+0800 [-] [caldav-2] [-] [twistedcaldav.storebridge.CalendarCollectionResource#error] Cannot create a calendar collection because there are too many already present in <twistedcaldav.directory.calendar.DirectoryCalendarHomeResource object at 0x10743a750>
...when I attempt to add more than 50 lists in the Reminders app. I had a similar issue in Mavericks. Is this "50" number available to modify in a config file somewhere?
My plan is to manage GTD-type projects in my Reminders apps (on iOS and OS X), but this limit is keeping me from creating a list for EVERY project I have.Woohoo! I set the integer to "500" and I now have over 200 lists added, and syncing, to my Reminders app and related tools.
Here's exactly what I did after reading the response from Linc Davis:
Stop the Calendar service
Create /Library/Server/Calendar and Contacts/Config/caldav-user.plist
Edit contents of "caldav-user.plist", setting your desired integer value:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>MaxCollectionsPerHome</key>
<integer>500</integer>
</dict>
</plist>
4. Start the Calendar service
Enjoy your many more lists.
Note that a file created in a place other than ~/ may have permissioning issues. To get around this, I made a copy of /Library/Server/Calendar and Contacts/caldavd-system.plist, then renamed and edited that file with nano in terminal. -
Cant' search for keywords - there are too many of them
It's probably a known bug/issue, but when you have to many keywords, you can't search for all of them.
This grey box pops up with all your keywords, which are ordered alphabetically. Unfortunately I'm not able see my keywords from A to L, because there are too many.
Here is an image to further illustrate what I mean.
http://farm4.static.flickr.com/3222/23789607331e284cabe4o.jpgThanks, what a bummer . I was hoping for a fix or a freeware solution :P.
Is there a way to notify Apple about this? Keywords seem poorly designed, or at least not thought through, compared to other programs. -

Hi, I'm moving my site from MobileMe to Filezilla and there is apparently a coding error on iWeb that means when I try to get onto my site there's no access online and it says there are too many redirects. Anyone have any idea what this might be?
Well, firstly Filezilla is not a hosting company but an ftp client that helps you upload your site to your new server. You need to purchase a new hosting account first though.
If you have iWeb 09 then you can publish directly to your new host and you select the publish to ftp option and not MobileMe - MobileMe won't be here after tomorrow.
You can also publish to a local folder if want to and use Filezilla to upload your site to your server.
You don't need re-directs as MobileMe won't be here so you need to cancel and delete your domain name from your MobileMe account and then cancel any domain name forwarding that you have at your domain name registrar - that is what the redirects are about.
Firstly ensure that you have your new hostings account - Filezilla is not a host, rather an ftp client that you use to upload your site. -

Alternatives to Cross Project Links
Hi,
Cross Project Links (External Tasks) is an out-of-the-box feature that allows to create dependencies between workplans.
The basic functionality has not changed from Project Server 2003 (or ever in earlier versions) to Project Server 2013, including Project Online.
Unfortunately it would be an understatement to say that it is not the ideal tool for creating dependencies of this sort. For example, There is no mechanism to preview and approve schedule changes (except the notorious "Links Between Project"
form), creating a dependency requires opening the all related workplans, there are many bugs associate to that, and this list goes on.
I'm looking for a 3rd party add-on that provides an alternative to Cross Project Links. What other tools would you recommend?
p.s. I've heard of 'TPG ProjectLink'. Had anyone tried it?Dominic,
I have to be honest
that I'm familiar only with the deliverables feature on Project Server 2007, and not with any updates on 2010 and 2013 versions.
I have invested many
hours in investigation of this tool and read documentation by Microsoft and bloggers, and reach the conclusion that this is not the right tool for me.
As far as I know,
the deliverables feature has not been changed dramatically in the 2013 version, therefore I'm looking the alternatives.
Maybe you are looking for
