Excerpt: Rational ClearCase is a software tool for revision control (e.g. configuration management, SCM) of source code and other software development assets. It is developed by the Rational Software division of IBM. ClearCase forms the base of version control for many large and medium sized businesses and can handle projects with hundreds or thousands of developers. ClearCase supports two kinds of use models, UCM, and base ClearCase. UCM provides an out-of-the-box model while base ClearCase provides a basic infrastructure (upon which UCM is built) which allows for more flexibility. Both can be configured to support a wide variety of needs. ClearCase can run on a number of platforms including AIX, z/OS, Linux, HP-UX, Solaris and Windows. It can handle large binary files, large numbers of files, and large repository sizes. It handles branching, labeling, and versioning of directories. ClearCase was developed by Atria Software and first released in 1992 on Unix and later on Windows. Some of the Atria developers had worked on an earlier system: DSEE (Domain Software Engineering Environment) from Apollo Computer. After Hewlett-Packard bought Apollo Computer in 1989, they left to form Atria. Atria later merged with Pure Software to form PureAtria. That firm merged with Rational Software, which was purchased by IBM in 2003 . IBM continues to develop and ma...More: http://booksllc.net/?id=343023

Posted: Oct 15, 2010 01:43:37 PM   in response to: JonesWong in response to: JonesWong's post The easy way for you is to fire up the IM GUI and see whether it shows it as available to you. If its grayed out, it's not for the platform that you are running on.
In PA-Online there is a separate package for every OS. They usually have names that start with CA and end with .zip. While that name isn't descriptive for you, you do want to retain it as part of the file name you save it as as you can backtrack later what package you downloaded.
You "just" have to go into PA-online again and download the right package. If you don't have a PA-online logon you have to backtrack in your company who did the download originally and get them to download the right thing. You may want to look over their shoulder to make sure.

Posted: Oct 23, 2010 07:57:01 PM   in response to: JonesWong in response to: JonesWong's post I am having the same problem also.
I'm working with Windows Installer 1.4.1 and Rational apps 7.1.2 on a Windows 2008 server. I'm trying out the silent install on the server before moving to using the silent install on the PCs.
I created the install repository using the Windows Installer so WI is working fine on Windows.
I think the Sun reference is to Sun Java.

I'm not having the problem installing the apps using the IM GUI.

I've deinstalled and reinstalled so many times my head is spinning.

Posted: Oct 23, 2010 08:34:08 PM   in response to: JonesWong in response to: JonesWong's post The IM comes with Sun Java. I can see it in the ...\eclipse\jre_5.0.4.sr11_20091106a\jre\bin directory.

This is a new 2008 R2 server and it doesn't look like it has Sun Java installed. I thought that wouldn't be an issue. I'm just trying to install the thick clients.

This server has UAC turned on. I am logged in as Administrator and for extra measure I right clicked on the DOS prompt and am running the DOS session as Administrator. But since I can do this via the GUI it's definately a DOS/silent install issue. Possibly with 7.1.2 and IM 1.4.1 and silent install.

Has anyone gotten that combo to work?

Posted: Oct 23, 2010 10:27:53 PM   in response to: JonesWong in response to: JonesWong's post Even more information.

I looked at the file in my ..\users\..\temp\ directory and it is the ibmratl_lic.dll file.

And the software appears to be installed.

There's nothing in the log file to tell me more.

I didn't get the error when doing a silent install of CCRC but I did when trying to do a silent install of ReqPro and ClearQuest. So again that points to some FlexLM license related issue.

But I can connect to the license server and use the software.

I'm left not knowing if there's something that didn't install correctly.

Any ideas?

Posted: Oct 24, 2010 04:14:52 PM   in response to: JonesWong in response to: JonesWong's post I've been trying many ways to do a silent install for the client to a PC from a repository created on a server.

For testing purposes I installed Installation Manager on the PC also but normal end users will not have it so the install has to work without IM on the PC.

If I go to the ..\eclipse directory on the PC and type:
IBMIMc.exe --launcher.ini silend-install.ini -input \\\response_file\.xml it works.

If I try to use the servers installation of IM by typing something like -- \\\eclipse\IBMIMc.exe -- launcher.ini silend-install.ini -input \\\response_file\.xml

I have problems.

At first I was getting the same errors that JonesWong was having. Then I went to the server and modied the IBMIM.ini, launcher.ini and silentinstall.ini and updated the java path to be \\\ instead of C:\.

I stopped getting those errors and now what happens is the Installation Manager splash screen comes up for 10 seconds or so, shuts down and the DOS command aborts with no message.

Has anyone been able to create a client install repository on a Windows 2008 server which they've then successfully installed from a PC without accessing Installation Manager on the PC?

Thanks.

And even so, I was hoping to hear if anyone else was successfull. If so, then I'd think it's our specific setup/commands that were at fault.

Posted: Nov 02, 2010 09:24:09 AM   in response to: JonesWong in response to: JonesWong's post Very poor form of me to submit multiple updates to this ticket and then disappear. It's been a busy few weeks.

Our particular setup is probably different than yours and I'm not sure which error you guys are having. The first error is fixed by updating the jvm location in the ...\eclipse\launcher.ini, ibmim.ini and silent-install.ini files. True you may not need to do it for all 3 but why not.

In our case we're not installing Installation Manager on the end users PC. Instead we're pointing to ibmim on a server and then installing from a repository on the server.

Normally the 3 ini files would have a line that reads something like:
c:\....\eclipse\jre_5.0.4.sr11_20091106a\jre\bin\j9vm\jvm.dll
But for us there is no such directory or files on our C drive. We had to update the path to read:
\\\\eclipse.....\jvm.dll.

Then the second problem I had with the ibmim splash screen coming up and then shutting down and the install never really starting was because I was using UNC path to get to ibmim.exe. I had to map a drive to the server where ibmim is installed and from the command prompt on the PC change directories to that drive and execute the command from the eclipse directory on the server.

If you're still having problems please detail the steps you're going through and where the download, repository and installation manager files reside.

Posted: Nov 04, 2010 05:52:06 PM   in response to: JonesWong in response to: JonesWong's post I did faced the issue. It is purly JVM path issue.

Say you have IM in

c:\IM\1.4.1\

Goto C:\IM\1.4.1\jre_5.0.4.sr11_20091106a
Copy the "jre" folder"
Go back to c:\IM\1.4.1\
Paste it.

This will resolve all your issues.

After doing the above try executing this.

\\itdqc002\C$\IM\1.4.1\installc.exe --launcher.ini silent-install.ini -input \\itdqc002\C$\response_file\install_clearcase71.xml

Transfer to New Owner of all streams in a ClearCase VOB / Possible script?

That the real pain point with the lock mechanism: if you unlock (which you need to do if you want to perform a cleartool protect -chown), you are loosing the list of users you excluded from a given lock.

A starting point to script that kind of operation is this IBM document "How to list locked VOBs":

Windows: for /F %v in ('cleartool lsvob -short') do cleartool lslock vob:%vUnix: for i incleartool lsvob -short -host ; do cleartool lslock vob:$i; done

Leave me as a comment the Os on which you will perform those operations, and I will complete this answer with a script.

For instance, a quick DOS script chown_locked.cmd would be:

@ECHO offSETLOCAL ENABLEDELAYEDEXPANSIONdoskey ct=cleartool $*set ucmObject=%1 & REM #project:aProject@\aPVob or stream:aStream@\aPVobset anOldUser=%2 & REM #previous owner of the streamsset anOldUser=%anOldUser:~0,-1%set lsstreamCmd=ct lsstream -in %ucmObject% -fmt "%%Xn %%[locked]p %%u\n"for /F "tokens=1-3" %%a in ( ' %lsstreamCmd% ') do ( rem echo '%%a' rem echo '%%b' rem echo '%%c' if "%%b" EQU "locked" ( if "%%c" EQU "%anOldUser%" ( call:chown %%a %USERNAME% ) else ( echo.ignore locked %%a because not owned by %anOldUser%, but by '%%c' ) ) else ( echo.ignore unlocked %%a ))goto end:chown ucmObject -- chown on a ucm object:: if lock, will restore the nusers lock exception list:: -- streamName [in] name of the UCM object:: -- newOwner [in] name of new owner SETLOCAL ENABLEDELAYEDEXPANSIONset ucmObject=%~1set newOwner=%~2set cmd=ct lslock %ucmObject%for /F "tokens=4*" %%a in ( ' %cmd% ^| find "Locked except for users:" ') do set lslock=%%bset lslock=%lslock:~0,-1%rem echo lslock '%lslock%'if "%lslock%" NEQ "~0,-1" goto lslockecho.chown locked '%ucmObject%%' for '%newOwner%'ct protect -chown %newOwner%2 %ucmObject% & goto endchown:lslockset lslock2=%lslock: =,%rem echo lslock2 '%lslock2%'echo.chown locked '%ucmObject%' for '%newOwner%' while retaining '%lslock2%'ct unlock %ucmObject%ct protect -chown %newOwner% %ucmObject%ct lock -nusers %lslock2% %ucmObject%:endchown( ENDLOCAL)EXIT /b:end( ENDLOCAL)

Call it on a project, or a stream (with sub-streams) within a project, like so:

chown_locked.cmd project:myProject@\aPVobName aPreviousOwnerchown_locked.cmd stream:aStream@\aPVobName aPreviousOwner

It will protect any sub-stream to the current user if said sub-streams are:

lockedlocked with the right owner (the previous one who has left)

If a sub-stream is locked with a -nusers list of excluded users (excluded from the lock), this list is saved before the unlock, and restore when locking the stream again.

Of course, it will only work if the current user is ClearCase administrator (i.e. is in the same group than the ClearCase_albd user): only this king of user can do a chown on a ClearCase object.

merge of directories in clearcase

It depends on the history of the two versions of a directory being merged from one branch to another:

if one version has removed files (i.e. has less files than the other version)if said version is merged onto the other,

the resulting version will have less files than initially shown in the view.

That could be because:

that view is not the one used for the mergethat view is the correct one, but with an eclipsed or hijacked content (privates files replacing versioned files)

In any case, what would help in the mentioned view is:

a 'cleartool ls' in the directory mergeda 'cleartool ls' in the parent directory of the directory merged.

The output of those two commands would help to confirm the exact status of the files merged within that directory, as well as the status of the directory itself.

Re: Setting up ClearCase with Quality Center

Registered: Sep 29, 2010 12:34:45 PM Setting up ClearCase with Quality Center
Posted: Dec 08, 2010 11:06:28 AM We have 7.1.1.2 of ClearCase and 9.2 of Quality center. I need to add the versioning and trying to follow the steps and one of the first ones is:

Add TDUser and TDVersion as string attributes to the ClearCase VOB

I'm new to CC so I need to respectfully request that you dont go over my head with any answers :)

How do you add these as attributes?

Has anyone set this up before? I have been reading like crazy and all I have to show for it so far is a headache. This forum has been so much more helpful then any documentation I have found. So thank you all for that!

Registered: Sep 29, 2010 12:34:45 PM Let me add one more if I may:
You must run this installation with the same user name that was used to run
the Quality Center installation.

I was not here when they did the QC installation, how can I tell what the user name used was?

Registered: Apr 08, 2008 11:40:52 PM Re the user name...

Does the install run on Windows? My guess is that they didn't ask for userid that ran the installation but rather the userid assigned during the installation to own the QC services etc.

If is just the userid that ran the install then this will probably be the owner of the files it installed. So just do properties on files in the appropriate C:\Program Files\... directory

If it is the "owning" user id it probably creates a service and sets it to run as some userid. Take a look in Services and do a properties - look at the Log On tab.

Re the attributes...

Is that exactly what it says about the attributes? There are several options that could apply. In general there are two ways:
1. Command line:
Usually you would change directory into a directory inside the vob. Assuming you are on windows with a view called dynamic and a vob called \hpqc...M:cd \dynamichpqccleartool mkattype -vtype string -c "For Quality Center" TDUser
2. Gui:
Start IBM Rational ClearCase/Type Explorer
Select your Vob
Double click Attribute Types
Right click on the page and select "Create..."
Follow the dialog

Registered: Sep 29, 2010 12:34:45 PM Mark,

Thanks for the reply. Page 12 of http://update.external.hp.com/qualitycenter/qc90/version_control/rcc_vc/qc_9_2/VCRCC.pdf is what I'm looking at for this. It is HP's Rational ClearCase Version Control Add-in Guide. Maybe I'm misreading something. Cant hurt to create a "string" attribute type I would think so I will give that a shot.

I've been given the opportunity to admin ClearCase with about 6 hours training and no prior experience. It has been a fun ride to say the least the last couple of months. Nothing has been easy per say and top that off with CC is a side project from my regualar QA work. Reading this site has been so much more help then any of the documentation I have been reading.

I hadn't used command lines since my old 8088 dos no windows 640k 20mb hd pc died but seems like alot of CC work is done via command lines. Good times!

Posts: 16
Registered: Sep 29, 2010 12:34:45 PM Ok so I think I needed to just create two string attributes under the VOB, I did this via the Type Explorer. That seems to make sense, not quite what you had me doing I dont think but it helped me find that.

Now to figure out the user issue.

I see an empty screen.
Could you give me more detail further description about "Ping uses ICMP port 8 called "echo" ?

There is a RFCs collection where all those protocols and their usage is explained.

In short when you ping a remore machine, your PC does send a "hello" message to the address you wish to enquire.

In human terms:

hello AAA I am ZZZ do you read me?

hello ZZZ this is AAA and I read you

When you use:

ping address -a

you ask the remote machine to supply you its human readable name known as DNS

Also the ICMP set is used to build a matrix of machines in a LAN

The full RFC list can be found in here: www.rfc-editor.org

Then you can ignore telnet, ping etc. for now: this is useful knowledge in general, but it won't help you in this case.

Posted: Nov 23, 2010 09:36:01 AM   in response to: shingirl in response to: shingirl's post This seems to be going around in circles...

Some important tests:
1) Verify that a "loaded" ping (packet size of at least 4096 bytes) works. "ping -l 5120 {registry server name}" is a useful command to test this...
2) Verify whether you can do an lsvob of a known VOB tag. "cleartool lsvob \myvob" If this works, while a full lsvob fails, you most likely have a firewall configuration that is blocking the full communication.

If the single-VOB lsvob fails, then verify that you can actually communicate with the albd port on the server host. The best command for that is the old windows "telnet" program. The syntax is "telnet {registry server name} 371", and if this is successful, you will see NOTHING. If it fails, you will get an error like this:
Connecting To ...Could not open connection to the host, on port 371: Connect failed

If the telnet fails that way, you need to determine why you cannot perform this basic communication and resolve the issue. The possible causes are:
1) Name resolution. The server's host name may resolve to an incorrect address in DNS
2) Client-side firewall issue. The ClearCase commands from this host may be getting blocked by a firewall on the client. You would be able to see this in a network trace started on the client, because you will see no communication going out to port 371.
3) intermediate firewall issue.

Note: If the registry server is also this client's ATRIA license server (check clearcase control panel or cleartool hostinfo -long), then the fact that you are NOT getting a license error indicates that basic communication with the albd works.

Why is this better than albd_list???

Posted: Nov 23, 2010 11:22:38 AM   in response to: shingirl in response to: shingirl's post Well, albd_list is great if you're on the server and looking to see what the child processes of the albd are. If you need to verify ability to get to the port, telnet has the advantage of completely eliminating clearcase from the client-side picture.

This may be an advantage if the test fails, but not, as here, if it succeeds.

There is probably an other firewall between your client and the registry server, and this one blocks the port for a short period of time as soon as one request results in too many replies, as a way to avoid 'denial of service' attacks.

You need to identify this firewall, and to reconfigure it.

Start with 'tracert '
Assuming it is not blocked...

In good old times, one recommended to place all the ClearCase hosts in a 0-hop LAN...

Posted: Dec 08, 2010 12:59:26 PM   in response to: shingirl in response to: shingirl's post Shingirl,

That was our initial assestment.

Nowadays most popular Antivirus act also as firewall, more complicated than default Windows one, where common ports are the only open.

The suggestion, as already made to you, is to kill or temporary disable the Antivirus or any similar programme that might interact with network traffic.

To make and additional suggestion you want to use a programme that will tell you which port are open or close. Google for one, there are several freeware ones.

Cheers

Posted: Dec 08, 2010 04:23:57 PM   in response to: shingirl in response to: shingirl's post Since "cleartool lsvob \vob1" works while plain "cleartool lsvob" fails, the issue is almost guaranteed to be in the switch/router/firewall between the client and the registry server. Why did I put the 3 together? Because in some cases the same box performs all 3 jobs. (High end Cisco gear is known for doing this, for example...)

Take a network trace of the transaction at both the client and the server end of things. Odds are that you will see the full "list vobs" output in the server-end trace, and only the FIRST packet of that response in the client-side trace. If so, please take a CLOSE look at the raw packets in the server side trace. What you will probably see is that the packets are leaving the server with the "do not fragment" bit set, and 2 out of 3 packets with that bit set also have non-zero fragment offset values. This combination of options is blocked by some intrusion detection systems to prevent denial-of-service attacks caused by spraying the target with bogus fragmented packets (which then will "sit around" for a while in memory waiting for the first fragment...).

How do you fix this, you tweak the firewall / Intrusion detection settings to allow these packets to go through.

Actual steps are (unfortunately) vendor specific.

Posted: Dec 08, 2010 11:06:28 AM We have 7.1.1.2 of ClearCase and 9.2 of Quality center. I need to add the versioning and trying to follow the steps and one of the first ones is:

Add TDUser and TDVersion as string attributes to the ClearCase VOB

I'm new to CC so I need to respectfully request that you dont go over my head with any answers :)

How do you add these as attributes?

Has anyone set this up before? I have been reading like crazy and all I have to show for it so far is a headache. This forum has been so much more helpful then any documentation I have found. So thank you all for that!

Does the install run on Windows? My guess is that they didn't ask for userid that ran the installation but rather the userid assigned during the installation to own the QC services etc.

If is just the userid that ran the install then this will probably be the owner of the files it installed. So just do properties on files in the appropriate C:\Program Files\... directory

If it is the "owning" user id it probably creates a service and sets it to run as some userid. Take a look in Services and do a properties - look at the Log On tab.

Re the attributes...

Is that exactly what it says about the attributes? There are several options that could apply. In general there are two ways:
1. Command line:
Usually you would change directory into a directory inside the vob. Assuming you are on windows with a view called dynamic and a vob called \hpqc...M:cd \dynamichpqccleartool mkattype -vtype string -c "For Quality Center" TDUser
2. Gui:
Start IBM Rational ClearCase/Type Explorer
Select your Vob
Double click Attribute Types

Thanks for the reply. Page 12 of http://update.external.hp.com/qualitycenter/qc90/version_control/rcc_vc/qc_9_2/VCRCC.pdf is what I'm looking at for this. It is HP's Rational ClearCase Version Control Add-in Guide. Maybe I'm misreading something. Cant hurt to create a "string" attribute type I would think so I will give that a shot.

I've been given the opportunity to admin ClearCase with about 6 hours training and no prior experience. It has been a fun ride to say the least the last couple of months. Nothing has been easy per say and top that off with CC is a side project from my regualar QA work. Reading this site has been so much more help then any of the documentation I have been reading.

I hadn't used command lines since my old 8088 dos no windows 640k 20mb hd pc died but seems like alot of CC work is done via command lines. Good times!

Now to figure out the user issue.

ClearCase equivalent of SVN's 'svn:externals'

There is no equivalent in ClearCase to Subversion's svn:externals property. The closest you can get is using ClearCase's internal symbolic links via the cleartool ln -s command. If you're linking files, you can try using hard links, but they can cause user confusion.

I've had problems with svn:externals and have stopped using them. It is way too easy to specify an actively changing HEAD as the svn:externals link, and then forget about that when you create a tag. That can cause your tagged version to change without your knowledge.

In order to get around this you should only tag to a specified revision AND make sure you use revision pinning since a later revision might move or delete the directory tree you were linking to. (There's a debate whether a link to the tags directory counts as a specified version, or whether you really need to use -r).

A better way is to treat directories from subcomponents your linking to via things like svn:exterals as actual releases and store them on some sort of release server. When you do your build of your application, you copy the needed files from the release server to your project much the way Maven and Ant/Ivy do. If your release is really just source code, you can store it on your release server as a tarball.

The big advantage is that this method is now independent of special features in your version control system.
