In every shop I've worked in prior to the current shop, selected CICS regions were typically shutdown after business hours in an effort to free up CPU cycles for the nighttime batch processes. Then, they would be restarted the following morning before the start of business. Many more regions stayed up 24x7x365.
In the current shop, almost all regions are shutdown at various points during the night, then restarted the following morning. I'm told this is NOT done to free up CPU cycles. Why then would our two Command Centers want to do this (I have to code for the ever-hanging schedules, which is why I'm interested)? |

In my shop, this is done when transaction files are updating the main database files during the nightly cycle. It ensures no one is updating the transaction files during the cycle.

Hello,
At several of the places i've been, this is the "nightly batch window". It is also when new/modified online modules are "rolled in". Less often these days, but once was when backups of online files were taken.
When your operating plan is built around this scheme, it lasts for a long time. |

Hi,
In my Shop, we have payroll system (Online screens to book hours) which will maintain the hours booked by customers. Our nightly batch which will perform the payroll processing will close the files allocated o the online system and creates payroll.
Main reason for closing the regions would enable the batch processing to take up.
Apart from this , as you told CPU cycles, recycling works are done. |
