Can we run schedule job one after another?

[Kiran Kumar 76]

I recently viewed scheuled jobs configured in system i see many daily jobs scheduled run/trigger at same time 

Queries

1. will schedule jobs trigerring/scheduled at same time hamper performance of system

2. can we club all the jobs running at same time and execute one after another?

"slowness" can be a ton of things, not just schedule jobs.

First try to pinpoint what is experienced as slowness. Is it the whole instance, everything you do. Is it browser specific. Is it related to a specific proces/table. Specific users. Obviously do system checks, slow running queries, long running jobs, etc.. Do normal checks like system logs. Also look at performance metrics. Is it sudden, where there any recent changes (for example very bad scripting 😁)? Are all nodes up? Etc..

You can always try to reach out to ServiceNow Support.

Hi @Kiran Kumar 76 

Greetings!!

Sorry for delay in response. When you say slowness, how you detect this, like loading any form/ report / login where you find. There can be many reasons for slowness. might be code you build , might be flow and might be jobs. 

My thought, lets narrow down , the issue and then try to see on these parameters.

Hi there,

Such a question cannot simply be answered. Also just look at out-of-the-box scheduled jobs. You will find a ton that run on exactly the same time. Is that an issue? Most cases: no. If you look at running jobs, you might also see that some jobs run for hours. Is that an issue? Doesn't have to be (I would pay attention to such though). Running 20 jobs at the same time for 1 minute, can be oke, can also cause a serious spike. It's also just a matter of testing, and knowing what those jobs in depth do. Who knows... they do a cacheFlush 🤣
