How to Increase Apache Request Per Second ? By default, Apache web server is configured to support 160 requests per second. As your website traffic increases, Apache will start dropping additional requests and this will spoil customer experience.  Here’s how to increase Apache requests per second. 1. Install MPM module We need to install MPM Apache module to be able to increase Apache requests per second. You can use mpm_worker or mpm_event module for this, instead of mpm_prefork module which consumes a lot of memory. You can easily install MPM module in Apache with following command For CentOS7/RHEL7 : Adjust /etc/httpd/conf.modules.d/00-mpm.conf Comment the line LoadModule mpm_prefork_module modules/mod_mpm_prefork.so by adding # in front of it. Uncomment the line LoadModule mpm_worker_module modules/mod_mpm_worker.so by removing # in front of it. For Ubuntu/Debian :  Use a2dismod / a2enmod to disable mpm_prefork and enable mpm_worker 2.

How Does S3 works with AEM ?

Image
How Does S3 works with AEM  ? Accommodating a huge amount of assets in any content management platform is challenging. Adobe Experience Manager offers an integration with the Amazon S3 storage solution, allowing binary data for images, documents and videos to be stored in an S3 bucket. Amazon S3 is highly performant and offers nearly infinite storage capacity.   When talking about terabyte storage, performance is everything. The choices made during the planning and architecting phase can literally make or break the performance of a CMS system and the websites running on it.  Adobe Experience Manager offers a number of storage methods, each offering a different way of storing data. Each of these options has its strengths and weaknesses. In AEM storage the mechanisms are called Micro Kernels, or MK for short.  In this article we will look at the AEM with S3 data store. For the detailed steps for S3 configuration you can refer -  https://www.aemrules.com/...

How to Sync HMAC in AEM ?

Image
Crypto Support in AEM (Syncing HMAC among AEM instances) AEM OOTB provides a feature where we can encrypt the secured and confidential data through OOTB AEM Crypto Support and store it in a code repository in the form of OSGi configuration. Crypto Support is based on keys (hmac and master files) which are unique for each AEM instance. Encrypted text generated for the same plain-text string on one AEM instance will be different from another instance. This can raise alarms in cases where we have the same OSGi configuration values shared among Author and Publish instances under the same topology. For e.g. /apps/project/config.prod/com.day.cq.db.dbservice.xml Here DB password for Default DB Service will be same across all Prod AEM instances. So, in order to make sure that the same encrypted value works on all Prod instances, we will have to sync hmac and master files among Prod Author and Publish instances. Vital Points to know before HMAC SYNC  Sync of HMAC/keys will break the AEM SSL...
