I quickly realized that there were some changes in Documentum and, unfortunately, I don&#8217;t believe that it&#8217;s for the best! In this blog, I will talk about the DOCUMENTUM_SHARED environment variable. I tested that almost a year ago with a PostgreSQL binary but it&#8217;s the same for all Documentum 16.4 binaries. This isn&#8217;t a very technical blog, it&#8217;s more like a small reflection about what OpenText is currently doing.<\/p>\n<p>&nbsp;<\/p>\n<h3>I. DOCUMENTUM_SHARED is dead<\/h3>\n<p>&nbsp;<\/p>\n<p>In Documentum 7.3 or below, you could define an environment variable named DOCUMENTUM_SHARED before installing Documentum (see <a href=\"https:\/\/www.dbi-services.com\/blog\/documentum-silent-install-things-to-know-binaries-jms-installation\/\" target=\"_blank\" rel=\"noopener noreferrer\">this blog<\/a> for example) which would then be used to define where the Shared components of a Content Server should be installed. This include mainly the following:<\/p>\n<ul>\n<li>The DFC properties and libraries<\/li>\n<li>The Java Method Server (JBoss\/WildFly + all Applications)<\/li>\n<li>The Java binaries<\/li>\n<\/ul>\n<p>Starting with Documentum 16.4, this environment variable has been deprecated (see <a href=\"https:\/\/knowledge.opentext.com\/knowledge\/cs.dll\/kcs\/kbarticle\/view\/KB11002330\" target=\"_blank\" rel=\"noopener noreferrer\">KB11002330<\/a>) and Documentum will simply ignore it. So, you will end-up with all the above components being installed right under $DOCUMENTUM, with everything else. I don&#8217;t like that because on Linux, we are used to split things and therefore, we are used to have only a few folders under $DOCUMENTUM and a few others under $DOCUMENTUM_SHARED. Now everything is put under $DOCUMENTUM and even the DFC files\/folders. By default in your 16.4 dfc.properties, you will have a definition of &#8220;<em>dfc.data.dir=&#8230;<\/em>&#8221; which points to $DOCUMENTUM as well ($DOCUMENTUM_SHARED before) so you will end-up with a lot of ugly stuff right under $DOCUMENTUM and it becomes messy! These are the DFC files\/folder I&#8217;m talking about:<\/p>\n<ul>\n<li>$DOCUMENTUM\/apptoken\/<\/li>\n<li>$DOCUMENTUM\/cache\/<\/li>\n<li>$DOCUMENTUM\/checkout\/<\/li>\n<li>$DOCUMENTUM\/export\/<\/li>\n<li>$DOCUMENTUM\/identityInterprocessMutex.lock<\/li>\n<li>$DOCUMENTUM\/local\/<\/li>\n<li>$DOCUMENTUM\/logs\/<\/li>\n<\/ul>\n<p>Obviously you can change the definition of the &#8220;dfc.data.dir&#8221; so this will be put elsewhere and you should really do that for all dfc.properties file but that&#8217;s kind of surprising. When I&#8217;m doing a review of an environment or an assessment of some sort, the first thing I&#8217;m always doing is going to the $DOCUMENTUM folder and listing its content. If this folder is clean (no log file, no backup, no temp files, no cache files, aso&#8230;), then there is a good chance that the complete installation is more or less clean as well. If there is a lot of mess even on the $DOCUMENTUM folder, then I know that it&#8217;ll be a long day.<\/p>\n<p>&nbsp;<\/p>\n<h3>II. long live DOCUMENTUM_SHARED! (for now)<\/h3>\n<p>&nbsp;<\/p>\n<p>So why am I saying that? Well as always when you try to deprecate something, there are leftovers here and there and it&#8217;s pretty hard to change people&#8217;s mind&#8230; Take for example the &#8220;docbase&#8221; VS &#8220;repository&#8221;&#8230; Since Documentum 7.0, a &#8220;docbase&#8221; is now officially called a &#8220;repository&#8221; but yet, a lot of people still uses &#8220;docbase&#8221; and even Documentum does (there are a lot of remaining references everywhere). I believe it will be the same for DOCUMENTUM_SHARED.<\/p>\n<p>At the moment in Documentum 16.4, there are the following references to DOCUMENTUM_SHARED:<\/p>\n<ul>\n<li>D2 16.4 still uses DOCUMENTUM_SHARED to know where the components are installed. This is used to deploy D2 libraries into the JMS mainly. I didn&#8217;t check but I guess it will be the same for the BPM\/xCP<\/li>\n<li>MigrationUtil (change <a href=\"https:\/\/www.dbi-services.com\/blog\/documentum-migrationutil-1-change-docbase-id\/\" target=\"_blank\" rel=\"noopener noreferrer\">docbase ID<\/a>, <a href=\"https:\/\/www.dbi-services.com\/blog\/documentum-migrationutil-2-change-docbase-name\/\" target=\"_blank\" rel=\"noopener noreferrer\">docbase name<\/a>, <a href=\"https:\/\/www.dbi-services.com\/blog\/documentum-migrationutil-3-change-server-config-name\/\" target=\"_blank\" rel=\"noopener noreferrer\">server config name<\/a>, aso&#8230;) still uses DOCUMENTUM_SHARED to know where the dfc.properties is, where the JMS is, aso&#8230;<\/li>\n<li>dm_set_server_env scripts still uses DOCUMENTUM_SHARED for defining other variables like LD_LIBRARY_PATH or CLASSPATH<\/li>\n<\/ul>\n<p>Because of these remaining references (and probably much more), OpenText didn&#8217;t just remove completely the DOCUMENTUM_SHARED variable&#8230; No, it&#8217;s still there but they put it, with a hardcoded value (same as $DOCUMENTUM), directly into the dm_set_server_env scripts so other references are still working properly.<\/p>\n<p>OpenText just probably didn&#8217;t want to completely remove the environment variable directly so they are proceeding step by step. First ignoring it and they will probably remove it completely in a future major version. Until then, I will continue to define my DOCUMENTUM_SHARED environment variable but for Documentum 16.4, I will set it with the same value as DOCUMENTUM because we never know, maybe in the next version, the variable will come back&#8230; ;).<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In June last year, I did my first manual installation (so without docker) of Documentum 16.4 and I was testing it with PostgreSQL.
