ClearCase on our Days!

Welcome to ClearCase on our Days Blog! How to segregate view stores path CCRC WAN Unix/Linux?

PedroMoura Tags: on linux wan views build unix segregating clearcase ccrc scm blog interoperability ‎ 4,053 Views

Hi Everyone,

This is my first entry on this blog that intents to be a place to share and discuss some day-by-day things that we learn on using ClearCase.

Today let me share this:

"On CCRC WAN UNIX/Linux (8.0.x) or CM_Server (7.1.2) how could we prevents users to access elements into view stores, since by default
that directories has 775 as permission?"

When using CCRC, a "checked out" process will copy an element in /var/adm/atria/ccweb/<username.domainname>/<view-name>
The above "path is created by root and then changed by root to be owned by the view creator".

Given the above we could manually change the permissions on view store paths, see the example below:

1) I changed the users directory permissions (on ccweb) to 750 on
/var/adm/atria/ccweb/

drwxr-x--- 3 john abc 4096 Dec 12 15:58 john.foo.abc
drwxr-x--- 4 maria xyz 4096 Dec 11 13:14 maria.<unknown>
drwxr-x--- 4 paul abc 4096 Dec 12 15:56 paul.<unknown>

#######
Note: For each user on tests below I configure their primary group as
ClearCase Primary Group.

2) Then from a client I logged as john and I was able to:

2.1) Access the John's views.

2.2) Create new views.

2.3) Access and update Paul's views (Note: I used the same client
machine to test the three users).
as expected since Paul belongs to abc group also.

2.4) I could access the maria's views files that were already stored on
the local file system (client machine) however I was not able to
update from the repository and checkouts.

Then I disconnect from Wan Server and closed the client tool.

3) I did the same test above as Paul (accessing John's views also) with
the same results.

4) Using maria account.

4.1) Access the Maria's views.

4.2) Create new views.

4.3) I could access the john and paul's views files that were already
stored on the local file system (client machine) however I was not able
to update from the repository and checkouts.

The problem on this approach is: if you have a new user the directory
will be created as 775 and you need to do the change by hand as
described above.

Adding repositories to install (or upgrade) ClearCase on Installation Manager console mode

pedromoura Tags: upgrade console imcl mode clearcase ‎ 573 Views

Hey ClearCase peers, here you have an step-by-step example on how to add two repositories (main media and fix)
to install CC using console mode (can be used to upgrade as well) .

Note1: On my example CC 9 media is extracted to /tmp/cc/cc90/ and the file which I must point on IM as repository is /tmp/cc/cc90/disk1/diskTag.inf

Note2: And CC 9.0.0.3 fix media is extracted to /tmp/cc/cc9003 and the rile which I must point on IM as repository is /tmp/cc/cc9003/repository.config

Note3: This only works for CC, but not for ClearQuest.

As root run:

/opt/IBM/InstallationManager/eclipse/tools/imcl -c

3 examples of ClearCase reformat VOB

pedromoura Tags: clearcase db_dumper reformatvob db_loader ‎ 825 Views

Hello everyone,

Here you have 3 examples with the steps while reformating a VOB, on the first you have a regular dump / load process using "cleartool reformatvob",

on the second we have a manual dump and load using db_dumper and db_loader tool, and the third example we have a dump made using "cleartool reformatvob" followed by a load using db_loader, util for the cases where a "cleartool reformatvob -load" fail.

MVFS failed to load on SuSE 12

PedroMoura Tags: 12 mvfs suse failed clearcase sles ‎ 2,851 Views

Hi,

Before prepare a SuSE 12 enviroment for ClearCase you must be aware

Btrfs is not supported by CC and if you have the root partition with that file system you will have problems to load MVFS

While starting CC you'll get:

# /opt/rational/clearcase/etc/clearcase start
ClearCase is stopped
Starting ClearCase
ClearCase daemons: albd_server modprobe: ERROR: could not insert 'mvfs': Invalid argument
Loading the MVFS was unsuccessful(8:1)
/opt/rational/clearcase/etc/clearcase: Loading MVFS failed

and from the syslog you'll see "ERROR: MVFS loaded with root directory not at file system root."

So install your SuSE with ext4, ext3, reiserfs or GPFS.

Take a look on this two Technotes to prepare your SLEs 12 for CC

Rational ClearCase does not support Btrfs as the root file system

How to change the Label ownership on ClearCase?

PedroMoura Tags: label ownership clearcase change linux ‎ 4,345 Views

Hi Guys

Today I will provide a short example on how to change the label ownership on Clearcase.

Example:

As paul I created a Label

[paul@machine-xyz vob4000]$ cleartool mklbtype -c "Label 1" Label-1-2-3
Created label type "Label-1-2-3".

I verified its ownership.

[paul@machine-xyz vob4000]$ cleartool describe -l lbtype:Label-1-2-3
label type "Label-1-2-3"
created 2014-05-14T16:31:48-04:00 by paul.john@machine-xyz
"Label 1"
instance mastership: unshared
owner: paul
group: john
scope: this VOB (ordinary type)
constraint: one version per element

Then logged as john (which is the VOB owner) I changed the label ownership by running:

[john@machine-xyz vob4000]$ cleartool protect -chown john lbtype:Label-1-2-3
Changed protection on "Label-1-2-3".

And finally I verified the ownership change.

[john@machine-xyz vob4000]$ cleartool desc -l lbtype:Label-1-2-3
label type "Label-1-2-3"
created 2014-05-14T16:31:48-04:00 by paul.john@machine-xyz
"Label 1"
instance mastership: unshared
owner: john
group: john
scope: this VOB (ordinary type)
constraint: one version per element

Unable to Full uninstall ClearCase 8.0.1.3 through response files

PedroMoura Tags: uninstallc uninstall installation clearcase manager ‎ 4,929 Views

Hi Everyone,

Let me share this uncommon situation and how to deal with it.

1) What is the problem?

Attempt to Full uninstall ClearCase by using response files provided by http://www-01.ibm.com/support/docview.wss?uid=swg21376355

failed to remove the related directories.

2) How to verify the problem?

For instance:

/var/ibm/InstallationManager/uninstall/uninstallc -input /tmp/clearcase_uninstall_response_linux_x86.xml

After that if you verify if ClearCase it was uninstalled you can't see the features anymore, however ClearCase mention still there:

Running:
/opt/IBM/InstallationManager/eclipse/tools/imcl listInstalledPackages
-features -long

It returns:

/opt/IBM/InstallationManager/eclipse :
com.ibm.cic.agent_1.7.1000.20131119_2219 : IBMÂ® Installation Manager :
1.7.1 :
/opt/ibm/RationalSDLC :
com.ibm.rational.clearcase.linux_x86_8.0.1003.0000-8-0-1-03-00-2014A-D1
40304
: IBM® Rational® ClearCase® - Linux x86 : 8.0.1.03 :

If you use find command (regular OS command) you see the ClearCase related files were deleted (-type f), but the directories (-type d) still there.

find /opt/ibm/RationalSDLC -type d | wc -l
    43
find /opt/ibm/RationalSDLC -type f | wc   -l
    0

3) What is the cause of the problem?

Based on some tests seems missing "com.ibm.rational.clearcase.check.unix.libraries.feature" on the response file is the current cause.
4) How to fix the problem?

Option 1:

To determine the features installed on the system, instead to use the command below - as suggested on the response files examples from http://www-01.ibm.com/support/docview.wss?uid=swg21376355

    #grep -i feature /var/ibm/InstallationManager/installed.xml | grep clearcaseunix

should be better if we run:

grep -i feature /var/ibm/InstallationManager/installed.xml |grep com.ibm.rational

which will provide all features and also com.ibm.rational.clearcase.check.unix.libraries.feature that missed on the response file.

      <package kind='feature' id='com.ibm.rational.check.link.feature'>
      <package kind='feature' id='com.ibm.rational.clearcase.check.unix.libraries.feature'>
      <package kind='feature' id='com.ibm.rational.clearcase.ctexplorer'>
      <package kind='feature' id='com.ibm.rational.clearcase.was.removal.warning.feature'>
      <package kind='feature' id='com.ibm.rational.clearcaseunix.CC_FULL'>
      <package kind='feature' id='com.ibm.rational.clearcaseunix.CC_MIN_STD_X'>
      <package kind='feature' id='com.ibm.rational.clearcaseunix.CM_Server'>
      <package kind='feature' id='com.ibm.rational.clearcaseunix.core'>
      <package kind='feature' id='com.ibm.rational.is.supported.unix.cc.feature'>
      <package kind='feature' id='com.ibm.rational.team.check.v7.feature'>

Using the information above you can edit the uninstall response file to:

<agent-input>
    <uninstall modify='false'>
        <offering
            profile='IBM Rational SDLC'
            id='com.ibm.rational.clearcase.linux_x86'
version='8.0.1003.0000-8-0-1-03-00-2014A-D140304'
            features='com.ibm.rational.team.check.v7.feature,
            com.ibm.rational.clearcase.check.unix.libraries.feature,
            com.ibm.rational.is.supported.unix.cc.feature,
            com.ibm.rational.check.link.feature,
            com.ibm.rational.clearcase.was.removal.warning.feature,
            com.ibm.rational.clearcaseunix.core,
            com.ibm.rational.clearcase.ctexplorer,
            com.ibm.rational.clearcase.cteupdatesite,
            com.ibm.rational.cc.cadence.virtuoso.integration,
            com.ibm.rational.clearcaseunix.CC_FULL,
            com.ibm.rational.clearcaseunix.CC_MIN_STD_X,
            com.ibm.rational.clearcaseunix.CC_ONLY_SERVER_X,
            com.ibm.rational.clearcaseunix.CC_MFC,
            com.ibm.rational.clearcaseunix.MS_FULL,
            com.ibm.rational.clearcaseunix.MS_ONLY_SHIPPING_SERVER,
            com.ibm.rational.clearcaseunix.CQ_CC_int,
            com.ibm.rational.clearcaseunix.CM_Server' />
    </uninstall>
</agent-input>

Option 2:

We could use "imcl uninstall" command pointing to the CC version ID installed.

/opt/IBM/InstallationManager/eclipse/tools/imcl uninstall <Version ID>

For instance:


/opt/IBM/InstallationManager/eclipse/tools/imcl uninstall
com.ibm.rational.clearcase.linux_x86_8.0.1003.0000-8-0-1-03-00-2014A-D1

Some useful commands to check CCRC WAN installation on Linux/Unix

PedroMoura Tags: linux profile http clearcase websphere ibm server unix ‎ 2 Comments ‎ 6,067 Views

Hi Guys,

While you are running to be prepared to Holidays, let talk about CCRC WAN, this feature on ClearCase 8.x replaces the CM_Server (from CC 7.1.x), the big difference here is WebSphere and IBM HTTP must be installed before you add the feature, in orther words WAS and IBM HTTP is not on ClearCase media anymore. Actually this post aims to talk about some post-installation commands - on Unix/Linux machines, anyhow let me share a link and one tip regarding the installation:

1) Guidelines regarding to prepare a machine to CCRC WAN are available on:

Installing or Upgrading to ClearCase and ClearQuest V8.0.1 with WebSphere Application Server and IBM HTTP Server V8.5

http://www-01.ibm.com/support/docview.wss?uid=swg21634430

2) After you have WAS and IBM HTTP installed, and while you are running Installation Manager to install or to add CCRC WAN feature, you will be asked to
to provide " CCRC WAN for WebSphere Application Server home directory", although the example on Installation Manager window shows

"/opt/IBM/WebSphere" if did a default installation of WebSphere, the WAS Application Server home directory should be instead:

/opt/IBM/WebSphere/AppServer

Ok, let me provide some commands to use to check your CCRC WAN installation:

NOTE: On my examples below my WAS application was installed on /opt/IBM/WebSphere/AppServer path:

a) Listing the profiles.

/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -listProfiles

[ccrcprofile]

b) Getting the path related to a profile.

/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -getPath -profileName REPLACE-HERE-WITH-PROFILE-NAME

Example:

/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -getPath -profileName ccrcprofile

/opt/ibm/RationalSDLC/common/ccrcprofile

c) Getting details about the profile.

cat REPLACE-HERE-THE-PATH-TO-THE-PROFILE/logs/AboutThisProfile.txt

cat /opt/ibm/RationalSDLC/common/ccrcprofile/logs/AboutThisProfile.txt

Application server environment to create: Application server
Location: /opt/ibm/RationalSDLC/common/ccrcprofile
Disk space required: 200 MB
Profile name: ccrcprofile
Make this profile the default: True
Node name: dfltNode
Host name: localhost
Enable administrative security (recommended): False
Administrative console port: 16060
Administrative console secure port: 16043
HTTP transport port: 16080
HTTPS transport port: 16443
Bootstrap port: 16809
SOAP connector port: 16880
Run application server as a service: False
Create a Web server definition: False
Performance tuning setting: Development

d) Verifying the CCRC server config file.

cat /opt/rational/clearcase/config/ccrc/server.conf

#Fri, 18 Oct 2013 16:07:47 -0400

ccrcTempDir=/var/tmp/ccrctemp
## ALERT : The default value of ccrcmaxSessionsOverall (was maxServerCount in previous release)
## has changed. Please check server.conf.sample before uncommenting the following line.
#ccrcMaxSessionsOverall=200
## ALERT : The default value of #ccrcMaxRequestsPerSession has changed.
## Please check server.conf.sample before uncommenting the following line.
#ccrcMaxRequestsPerSession=10

e) Stop/Start IBM HTTP Server and WAS.

Stop Process:

/opt/rational/common/ccrcprofile/bin/stopServer.sh server1 # Which is the PATH-TO-PROFILE/bin/stopServer.sh server1

/opt/IBM/HTTPServer/bin/apachectl -k stop

Start Process:

/opt/IBM/HTTPServer/bin/apachectl -k start

/opt/rational/common/ccrcprofile/bin/startServer.sh server1 # Which is the PATH-TO-PROFILE/bin/startServer.sh server1

Manipulating Necessary Services for CM_Server on Linux/Unix ClearCase Servers

PedroMoura ‎ 1,872 Views

Hi guys,

We know on to support the CCRC (ClearCase Remote Clients) on CC version 7.1.x we expected to have CM_Server feature installed on a Server.

When select CM_Server feature to be installed automatically you will have Websphere and IBM HTTP Server installed to suport it.

After you have them installed some times we fall on these question:

How to stop and start Websphere and IBM HTTP services if necessary?

Is easy to do, but before run the commands below be sure you can stop the services now, since the CCRC users will be unavaible to work with ClearCase.

As root you can use the following:

First stop WebSphere:
/opt/IBM/WebSphere/AppServer/bin/stopServer.sh server1

Then stop IBM HTTP:

/opt/IBM/HTTPServer/bin/apachectl -k stop

To start use:

First start IBM HTTP:

/opt/IBM/HTTPServer/bin/apachectl -k start

Then start WebSphere:

/opt/IBM/WebSphere/AppServer/bin/startServer.sh server1

In time, if you have issues with WebSphere or IBM HTTP Sever not running after a reboot (a machine restart), you should add the start scripts inside a script that will be read on boot process, for instance:

For a Red Hat add the following lines below on your /etc/rc.local file

/opt/IBM/HTTPServer/bin/apachectl -k start
/opt/IBM/WebSphere/AppServer/bin/startServer.sh server1

For next post, I'll show some interesting command but for CCRC WAN!

Regards,

Pedro Moura
