Hi,

Which version of java you updated and what is the version of AEM you are using? Can you check error.log to see what is the exception/errors you are getting while opening author/publish instance.

Error log will present under /crx-quickstart/logs/error.log.

Please share the error logs which helps us to analyze further on your issue.

Also check After upgrading Java version, AEM does not start up | AEM in case you are facing similar issue.

[hemanthm9258359]

I updated to java version "1.8.0_151". I am using AEM6.3.

Try Removing the following line from crx-quickstart/conf/sling.properties:

org.osgi.framework.system.capabilities=${eecap-${java.specification.version}}

i TRIED CHECKING THIS. no such line exist. Thank you.

Could you share the error.log and stderr.log snippets?

Low-memory action set to fork

Using 64bit VM settings, min.heap=1024MB, min permgen=256MB, default fork arguments=[-Xmx1024m, -XX:MaxPermSize=256m]

The JVM reports a heap size of 1024 MB, meets our expectation of 1024 MB +/- 20

No console, will fork to get enough memory

Not forking JVM as -nofork option is set

As Ravi mentioned above, allocate more RAM when starting up AEM. If you're using Mac, use top to check RAM used by AEM and assign more using -Xmx2048m or 4096m

[nikhilgupta86]

Try Removing the following line from crx-quickstart/conf/sling.properties:

org.osgi.framework.system.capabilities=${eecap-${java.specification.version}}

and start AEM it should work, worked for me.

[Prince_Shivhare]

could you please explain not working means?

are you able to see system/console/bundles ? or other consoles in aem?

[hemanthm9258359]

I cannot see any console.

[Ravi_Pampana]

It seems to be memory issue, try increasing memory and test. Check below post

trying to install CQ author instance ?

Also check whether system has sufficient free space
