I&#8217;ve just run a bit out of time, thats why I haven&#8217;t yet more screen shots to display. I&#8217;ll provide a few more later.<\/p>\n<h3>Round up<\/h3>\n<p>All together the installation of EM Cloud Control 12c is much easier than installing one of the earlier releases. Oracle finally packed all together in one software package and one installer. I do not have to care anymore about the right JDK or WLS version. They are just installed. The side effect on this is that also on the OS everything is installed on the same place. Where at 10g and 11g separate directories has been used for OMS and agent, they are now below the middleware directory. Which is not really an issue, you only need to adjust any scripts and environment variables.<\/p>\n<p>Apart from the simple installation procedure, I also like the small improvements while checking the prerequisites. Things which have to be fixed can be fixed immediately. Others, which are required to run the OMS, but not to finish the installation, can be fixed afterwards.<\/p>\n<p>The only drawback I see after my first short tests are the quite high CPU and memory needs. For a regular system, this is not really a problem. But for a road warrior where all testing is done on a notebook, a VM with a 4-6GB is quite an issue.<\/p>\n<h3>References<\/h3>\n<p>A collection of links to MOS Notes and Oracle documentation about Enterprise Manager Cloud Control 12c (12.1.0.1.0):<\/p>\n<ul>\n<li>Oracle Technology Network <a href=\"http:\/\/www.oracle.com\/technetwork\/oem\/grid-control\/overview\/index.html\">Oracle Enterprise Manager 12c<\/a><\/li>\n<li><a href=\"http:\/\/download.oracle.com\/docs\/cd\/E24628_01\/index.htm\">Enterprise Manager Cloud Control Documentation 12c Release 1 (12.1)<\/a><\/li>\n<li>MOS Note: <em>How to Install Enterprise Manager Cloud Control 12.1.0.1 (12c) <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=BULLETIN&#038;id=1359176.1\">[1359176.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>EM12c: How to install Enterprise Manager Cloud Control 12c Agent <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=BULLETIN&#038;id=1360183.1\">[1360183.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>How to Install Enterprise Manager Cloud Control 12.1.0.1 (12c)<br \/>\nusing Software-only Method <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=BULLETIN&#038;id=1364002.1\">[1364002.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>How to Install Enterprise Manager Cloud Control 12.1.0.1 (12c)<br \/>\nusing Software-only Silent Install Method with Response File <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=BULLETIN&#038;id=1364025.1\">[ID 1364025.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>FAQ: Enterprise Manager Cloud Control 12c Install \/ Upgrade Frequently Asked Questions <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=FAQ&#038;id=1363863.1\">[1363863.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>Enterprise Manager Cloud Control 12c Installation <br \/>\nList of the Log Files and Commands to Zip them into One Zip Archive <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;doctype=REFERENCE&#038;id=1363779.1\">[1363779.1]<\/a><\/em><\/li>\n<li>MOS Note: <em>Enterprise Manager Cloud Control 12c Agent Installation <br \/>\nList of the Log Files and Commands to Zip them into One Zip Archive <a href=\"https:\/\/support.oracle.com\/CSP\/main\/article?cmd=show&#038;type=NOT&#038;id=1367301.1\">[1367301.1]<\/a><\/em><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>After downloading the latest release of Enterprise Manager Cloud Control I&#8217;ve started a initial test installation.
