If you take a look at the dmr_content items attached to a specific document (parent_id), you will understand that there is by default only one PDF content while there might be a lot more jpeg renditions. Why? The answer to that is pretty simple, the content of the PDF rendition contains all the pages of the document while the jpeg renditions are only for a single page&#8230; Therefore if an ADTS is processing a document of 25 pages, then it will create 25 jpeg renditions. Actually that&#8217;s even more than that&#8230; Indeed by default the ADTS generates two types\/formats of jpeg renditions for each page which double the total number of renditions. Here are the two formats available by default:<\/p>\n<ul>\n<li>jpeg_lres: (Low Resolutions) that&#8217;s actually a real size preview in low resolution of the page<\/li>\n<li>jpeg_story: (StoryBoards) that&#8217;s a reduced size preview of the page, quite hard to read what&#8217;s written&#8230;<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>jpeg_lres is the format used by the Thumbnail Server and also by D2 for the preview widget. On the other hand, jpeg_story isn&#8217;t used at all in D2 4.5. According to EMC, it *might* has been used for D2 4.1 and previous versions but they aren&#8217;t sure about it&#8230; \ud83d\ude09<\/p>\n<p>&nbsp;<\/p>\n<p>Now that this has been said, let&#8217;s go back to the title of this blog. Because of this behavior of the ADTS, it might happen that one day you will see hundreds or even thousands of dmr_content items deleted. You might think that there is something wrong, that the cleanup jobs deleted too many objects or something like that&#8230; So if this happens to you, please take a look at the format of these dmr_content! Several months ago, the cleanup jobs were inactive for a few weeks because of a bug and when we reactivated them, this happened to us and we finally found out that 95% of these items where only jpeg renditions and that this was actually the expected behavior!<\/p>\n<p>&nbsp;<\/p>\n<p>After that, we started thinking about how we should handle these jpeg renditions for really big documents? Because having the preview of the documents available in D2 is great but then is it really needed? Generating a preview of the first page or of the 10 first pages might makes sense but would it makes sense to generate a preview for each page of a document bigger than 10 pages? 100 pages? 1 000 pages? These previews are used in D2 and you need to move from one page to the other one starting with the page 1. If you absolutely want to see the preview of the page *364* in D2, then you will need 20 minutes to reach that page in the first place&#8230; I think that downloading the document is a little bit faster ;).<\/p>\n<p>&nbsp;<\/p>\n<p>So is it possible to only generate previews for a few pages and setup a maximum number of jpeg renditions per document? The short answer to that is: yes! And that&#8217;s the purpose of this blog, wonderful, isn&#8217;t it?!<\/p>\n<p>&nbsp;<\/p>\n<p>First check out the configuration file that will need to be updated:<\/p>\n<pre class=\"brush: bash; gutter: true; first-line: 1; highlight: [16,22,28,31]\">[dmadmin@content_server_01 workspace]$ iapi DOCBASE -Udmadmin -Pxxx\n\n\n        EMC Documentum iapi - Interactive API interface\n        (c) Copyright EMC Corp., 1992 - 2015\n        All rights reserved.\n        Client Library Release 7.2.0050.0084\n\n\nConnecting to Server using docbase DOCBASE\n[DM_SESSION_I_SESSION_START]info:  \"Session 013f245a802173d6 started for user dmadmin.\"\n\n\nConnected to Documentum Server running Release 7.2.0050.0214  Linux64.Oracle\nSession id is s0\nAPI&gt; retrieve,c,dm_document where folder('\/System\/Media Server\/Command Line Files') and object_name = 'storyboard_pdfstoryboard.xml'\n...\n093f245a801c9075\nAPI&gt; checkout,c,l\n...\n093f245a801c9075\nAPI&gt; getfile,c,l,\/tmp\/workspace\/storyboard_pdfstoryboard.xml\n...\n\/tmp\/workspace\/storyboard_pdfstoryboard.xml\nAPI&gt; flushcache,c\n...\nOK<\/pre>\n<p>&nbsp;<\/p>\n<p>Then retrieve a test document that will be used to see how it is working:<\/p>\n<pre class=\"brush: bash; gutter: true; first-line: 1; highlight: [1,4]\">API&gt; retrieve,c,dm_document where r_object_id='093f245a801a8f56'\n...\n093f245a801a8f56\nAPI&gt; getfile,c,l,\/tmp\/workspace\/TestRenditions.docx\n...\n\/tmp\/workspace\/TestRenditions.docx<\/pre>\n<p>&nbsp;<\/p>\n<p>Ok so now the two files are stored locally.
