In a previous blog (click here), I presented a common issue that might occur during the installation of some DARs and how to handle that with what Documentum provides but there are some limitations to that. Indeed the script repositoryPatch.sh is pretty good (except the small bug explained in the other blog) but its execution is limited to only one docbase and it is pretty boring to always put the full path of the DARs file knowing that usually all DARs will be at the same place (or at least this is what I would recommend). In addition to that, this script repositoryPatch.sh might not be available in your Content Server because it is normally available only after applying a patch of the Content Server. Therefore we usually use our own shell script to deploy X DARs on Y docbases with a single command.

 

For this blog, let’s use the following:

  • Documentum CS 7.2
  • RedHat Linux 6.6
  • $DOCUMENTUM=/app/dctm/server
  • $DM_HOME=/app/dctm/server/product/7.2

 

I will propose you in this blog three different solutions to avoid the issue with the space in the name of a DAR and to be able to deploy all DARs that you want on all docbases that you define.

  1. Variable with space separated list
#!/bin/sh
docbases="DOCBASE1 DOCBASE2 DOCBASE3"
dar_list=("DAR 1.dar" "DAR 2.dar" "DAR 3.dar")
username="INSTALL_OWNER"
password="xxx"
dar_location="/app/dctm/server/product/7.2/install/DARsInternal"
 
for docbase in $docbases
do
        for dar in "${dar_list[@]}"
        do
                darname=${dar##*/}
 
                echo "Deploying $darname into $docbase"
                ts=$(date "+%Y%m%d-%H%M%S")
 
                $JAVA_HOME/bin/java -Ddar="$dar_location/$dar" 
                        -Dlogpath="$dar_location/dar-deploy-$darname-$docbase-$ts.log" 
                        -Ddocbase=$docbase -Duser=$username -Ddomain= -Dpassword="$password" 
                        -cp $DM_HOME/install/composer/ComposerHeadless/startup.jar 
                        org.eclipse.core.launcher.Main 
                        -data $DM_HOME/install/composer/workspace 
                        -application org.eclipse.ant.core.antRunner 
                        -buildfile $DM_HOME/install/composer/deploy.xml
        done
done

 

This is probably not the best solution because you have to manually add double quotes around each DAR name so that’s a little bit boring, unless you already have such a list. Please note that with this script, all DARs must be in the folder $DM_HOME/install/DARsInternal/ which is the folder used by Documentum by default for DARs.

 

  1. No variable but still space separated list
#!/bin/sh
docbases="DOCBASE1 DOCBASE2 DOCBASE3"
username="INSTALL_OWNER"
password="xxx"
dar_location="/app/dctm/server/product/7.2/install/DARsInternal"
 
for docbase in $docbases
do
        for dar in "DAR 1.dar" "DAR 2.dar" "DAR 3.dar"
        do
                darname=${dar##*/}
 
                echo "Deploying $darname into $docbase"
                ts=$(date "+%Y%m%d-%H%M%S")
 
                $JAVA_HOME/bin/java -Ddar="$dar_location/$dar" 
                        -Dlogpath="$dar_location/dar-deploy-$darname-$docbase-$ts.log" 
                        -Ddocbase=$docbase -Duser=$username -Ddomain= -Dpassword="$password" 
                        -cp $DM_HOME/install/composer/ComposerHeadless/startup.jar 
                        org.eclipse.core.launcher.Main 
                        -data $DM_HOME/install/composer/workspace 
                        -application org.eclipse.ant.core.antRunner 
                        -buildfile $DM_HOME/install/composer/deploy.xml
        done
done

 

Same as before for this one, you don’t need the @ trick since the list of DARs is in the for loop directly but you still need to manually put double quotes around the file names.

 

  1. Variable with comma separated list
#!/bin/sh
docbases="DOCBASE1 DOCBASE2 DOCBASE3"
dar_list="DAR 1.dar,DAR 2.dar,DAR 3.dar"
username="INSTALL_OWNER"
password="xxx"
dar_location="/app/dctm/server/product/7.2/install/DARsInternal"
 
for docbase in $docbases
do
        IFS=',' ; for dar in $dar_list
        do
                darname=${dar##*/}
 
                echo "Deploying $darname into $docbase"
                ts=$(date "+%Y%m%d-%H%M%S")
 
                $JAVA_HOME/bin/java -Ddar="$dar_location/$dar" 
                        -Dlogpath="$dar_location/dar-deploy-$darname-$docbase-$ts.log" 
                        -Ddocbase=$docbase -Duser=$username -Ddomain= -Dpassword="$password" 
                        -cp $DM_HOME/install/composer/ComposerHeadless/startup.jar 
                        org.eclipse.core.launcher.Main 
                        -data $DM_HOME/install/composer/workspace 
                        -application org.eclipse.ant.core.antRunner 
                        -buildfile $DM_HOME/install/composer/deploy.xml
        done
done

 

This version is my preferred one because what you need is just a list of all DARs to be installed and the separation is just a comma so that’s pretty simple to obtain and simpler to manage than double quotes everywhere. Now these versions will all provide the following output showing that the script is working properly even for DARs containing spaces in their names:

Deploying DAR 1.dar into DOCBASE1
Deploying DAR 2.dar into DOCBASE1
Deploying DAR 3.dar into DOCBASE1
Deploying DAR 1.dar into DOCBASE2
Deploying DAR 2.dar into DOCBASE2
Deploying DAR 3.dar into DOCBASE2
Deploying DAR 1.dar into DOCBASE3
Deploying DAR 2.dar into DOCBASE3
Deploying DAR 3.dar into DOCBASE3

 

So that was for the deployment of several DARs in several docbases. By default Documentum will consider that the username is “dmadmin”. If this isn’t the case, then this script will not work in its current state. Yes I know, we specified the user in the script but Documentum doesn’t care and it will fail if you aren’t using dmadmin. If you need to specify another name for the Installation Owner, then you need to do three additional things. The first one is to add a new parameter in the script that will therefore now look like the following:

#!/bin/sh
docbases="DOCBASE1 DOCBASE2 DOCBASE3"
dar_list="DAR 1.dar,DAR 2.dar,DAR 3.dar"
username="INSTALL_OWNER"
password="xxx"
dar_location="/app/dctm/server/product/7.2/install/DARsInternal"
 
for docbase in $docbases
do
        IFS=',' ; for dar in $dar_list
        do
                darname=${dar##*/}
 
                echo "Deploying $darname into $docbase"
                ts=$(date "+%Y%m%d-%H%M%S")
 
                $JAVA_HOME/bin/java -Ddar="$dar_location/$dar" 
                        -Dlogpath="$dar_location/dar-deploy-$darname-$docbase-$ts.log" 
                        -Ddocbase=$docbase -Duser=$username -Ddomain= -Dpassword="$password" 
                        -Dinstallparam="$dar_location/installparam.xml" 
                        -cp $DM_HOME/install/composer/ComposerHeadless/startup.jar 
                        org.eclipse.core.launcher.Main 
                        -data $DM_HOME/install/composer/workspace 
                        -application org.eclipse.ant.core.antRunner 
                        -buildfile $DM_HOME/install/composer/deploy.xml
        done
done

 

After doing that, the second thing to do is to create the file installparam.xml that we used above. In this case, I put this file in $DM_HOME/install/DARsInternal but you can put it wherever you want.

[dmadmin@content_server_01 ~]$ cat $DM_HOME/install/DARsInternal/installparam.xml
<?xml version="1.0" encoding="UTF-8"?>
<installparam:InputFile xmlns_installparam="installparam" xmlns_xmi="http://www.omg.org/XMI" xmi_version="2.0">
    <parameter value="dmadmin" key="YOUR_INSTALL_OWNER"/>
</installparam:InputFile>

 

Just replace in this file YOUR_INSTALL_OWNER with the name of your Installation Owner. Finally the last thing to do is to update the buildfile. In our script, we are using the default one provided by EMC. In this buildfile, you need to specifically tell Documentum that you want it to take into account a custom parameter file and this is done by adding a single line in the emc.install XML tag:

[dmadmin@content_server_01 ~]$ grep -A5 emc.install $DM_HOME/install/composer/deploy.xml
        <emc.install dar="${dar}"
                     docbase="${docbase}"
                     username="${user}"
                     password="${password}"
                     domain="${domain}"
                     inputfile="${installparam}" />

 

Once this is done, you can just restart the deployment of DARs and it should be successful this time. Another solution to specify another Installation Owner or add more install parameters is to not use the default buildfile provided by EMC but use your own custom buildile. This will be an ANT file (xml with project, target, aso…) that will define what to do exactly so this is highly customizable. So yeah there are a lot of possibilities!

Note: Once done, don’t forget to remove the line from the file deploy.xml 😉
