What are Operation Modes?

[Former Member]

I would just like to have deeper meaning with regards to Operation Modes. What are operation modes? Does this basically means that we can allocate additional resources (in terms of work process) to a specific operation? For instance, we need additional background work processes at night, we could simply switch the operation mode that is defined to add several background work processes for night? Is that it?

Are there any subtraction or addition of work processes? For instance, from only existing 5 background processes, we can make it to 10 background processes by activating or switching the operation mode?

Or is it simply reallocation of work processes to give way to the more priority in-need work processes? If it is simply reallocation? From what work process are we reallocating from? Does it signify that we can allocate several dialog work proceses and make it background processes? From 10 dialog process and 3 background process, we'll allocate 5 from dialog process to make the background process into 8?

Or is it simply reallocation of the current setting of the work processes? For instance, you have a total of 10 background processes defined in the profile parameter, then you set 2 bacground processes for day and 8 work processes for night. Is that it?

Which is the correct notion? Kindly clarify. Thanks.

Operations modes are generally different sets of work processes that can be setup to change at different hours of the day. One basic reason to use an operation mode is to invoke more background work process to run at night when fewer dialog users are on the system (allowing for the generating of reports and so on).

I do not know of a way to change operation modes when the load is higher on the system. In fact, that is something you would definitely not want to do since there is a tendency to lose buffered data when you switch operation modes.

Hope that helps.

Hi,

Operations modes just change the role (from DIA to BTC for exemple) of some work processes.

It is not possible to change the total number of work processes.

If necessary, It is possible to switch manually operation modes with RZ03.

On our systems we have 3 operation modes : Day, Night and Exceptional.

Day and Night are switched automatically with the time.

Exceptional mode is switched on manually very rarely when there is an "exceptional" need...

One trick to know : you need at least one UPD our UP2 process on a DI to be able to change the number of these processes vi operation modes.

So basically, the logic of operation mode is simply the reallocation of the different existing work processes? For instance, 10 dialog work process, 8 background process. We can allocate 2 dialog work process to become background process so that there will be 10 background work process all in all when night comes and the operation mode switched. Is the logic correct?

Hi,

The logic is perfectly correct !
