The Cron daemon can execute shell scripts at a specified time. In fact, it is the same as the bat file for Job Scheduling in windows.
# Crontab regularly executes commands (this is my main learning)
# At only once
# The batch system is scheduled for batch processing when the attachment is allowed
During system initialization, the cron daemon will check the crontab file and at record files, and immediately send the changes to the cron daemon for execution.
# Ps-ef | grep cron

Use two AX servers and upgrade to version 261. The latest aVCS feature of AX is used for automatic configuration synchronization. AVCS can be deployed on traditional HA, and can also be used with the VRRP-A to achieve automatic synchronization of Multi-virtual partition configuration (ADP with L2/L3virtualization ).Basically divided into two steps, the first step to configure the VRRP-A, the second part to configure aVCS.(1) VRRP-AThe configuration of

When I first came into contact with the Abp framework, the methods encapsulated in the framework for operating various types of data are still very useful. I am still learning about it and will use it. the methods used to operate PostgreSQL data in the nhib.pdf class library are recorded. If there are any deficiencies, let the comments give pointers and throw bricks.
