Create a new Logger into Adobe CQ

CQ allows you to create custom log files. You can define your own Logger by in CQ Web Console Configuration (/system/console/configMgr).

There are 3 steps to create a new logger:

·         Create a new instance of the Factory Configuration Apache Sling Logging Logger Configuration.

·         Set the Log level you wish (Trace, Debug, Info, Warn or Error).

·         Specify the Log File. For example, logs/example.log. This will be created automatically in your CQ logs folder.

·         Configure the Message pattern for formatting the log messages.

Specify the Loggers which will be logged into the new Log file. Here we usually give one or several java package names. Any message logged within those packages will end up in this new Log file. Each logger name applies for any child category unless configured otherwise. E.g. a logger name of org.apache.sling applies to logger org.apache.sling.commons unless there is a different configuration for org.apache.sling.commons

[PERFORMANCE] Adobe WEM/CQ performance tuning

Adobe WEM/CQ performance tuning Contents Caching-related configurations CRX Bundle cache CRX Search index handler (Lucene) cache Tar PM index cache Scalability Maintenance Optimizing Tar Files (for Tar Persistence Manager) Data Store Garbage Collection Main documentation you should consult first: http://dev.day.com/docs/en/cq/current/deploying/performance.html http://dev.day.com/content/kb/home/cq5/CQ5Troubleshooting/performancetuningtips.html Caching-related configurations CRX Bundle cache CRX caches bundles, consisting of a node with all its properties. This is used by all bundle-based Persistence Managers. The default size of BundleCache is 8 MB. If this is too small it can cause an excessive number of read-accesses to the underlying persistence layer. Set the bundleCacheSize to something larger than the default.

How to custom CQ Login Module

In order to manage the login process in our project, we will use a custom CQ Login Module. We will admit the root URL of CQ instance is: http://localhost:4502/ . This value may change depending of your environment. The %CQ_HOME% variable we will mention refers to the CQ install path. It admits you have defined %CQ_HOME% as an environment variable. 1.         Update the repository definitions The login module must be referenced in the repository definitions. You have to edit the next file: %CQ_HOME%/crx-quickstart/repository/repository.xml Do a copy of repository.xml to repository.xml.original In repostiory.xml, replace  security  part of repository.xml with following: <Security appName="com.day.crx">         <SecurityManager class="com.day.crx.core.CRXSecurityManager"> <WorkspaceAccessManager class="org.apache.jackrabbit.core.security.simple.SimpleWorkspaceAccessManager"/>  ...

[DAM] Custom DAM management / Add 'Alt' into images

Issue: We need, for each asset to be able to edit the ‘alt’ text. The ‘alt’ text must be used on the site each time an asset is displayed. When displaying an asset, the mechanism is the following : -       Get the Locale from the request -       When getting the asset, get the associated Alt property corresponding to the locale. -       Populate the alt attribute with this value. Resolution: To achieve this, we can customize the DAM Asset Editor. The AssetEditor is the form used to input asset properties and metadata. Below is a screenshot of a customized form with four “alt” input (for four different locales). The DAM uses the following nodes to render Asset Editor forms: -       /libs/dam/content/asseteditors/formitems -       /libs/dam/content/asseteditors/images/formitems -      ...
