[SagarJ957172966]

Dear Team,

We are on ServiceNow On-Prem instance with 3 App servers and total 15 nodes across the servers. 

We have seen slowness while accessing ServiceNow application. 

Please refer to below details;

OS Version :

NAME="Red Hat Enterprise Linux"
VERSION="8.10 (Ootpa)"

Database : Oracle 19c in cluster environment

I would appreciate if anyone can help me to resolve this issue.

Hello!

We're experiencing slowness on our ServiceNow On-Prem instance running RHEL 8.10 with Oracle 19c in a clustered setup across 3 app servers and 15 nodes. Key areas to check include server load, database performance, network latency, and heavy background jobs. Reviewing logs and optimizing JVM settings may also help identify and resolve bottlenecks. Any guidance would be appreciated.

Create ticket with ServiceNow and triple read the Self-hosted deployment install notes.

Make sure you are using the correct JDK based on this KB https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1362432

pay special attention to the Application Node configuration towards the end, the properties that need to be added to /glide/nodes/<node directory>/conf/overrides.d 

sometimes just missing one file or edit on 1 of 12 throws things off because a JVM svc keeps crashing or is not optimized.

Try Configuring Busy Polling on the Redhat host seems to speed things up for me.

Hello @Karen763Pur ,

Can you please help with recommended JVM setting. Also, we have NSX load balancer in our environment.
