SQL*Net message from client too important

in Oracle JDBC (MOSC) 10 commentsAnswered

"Oracle Database 19c Standard Edition 2 Release 19.0.0.0.0 - Production

Version 19.13.0.0.0"

------------------


Not easy to describe my problem but I will try

We noticed a slow processing problem with the database when migrating an application from a current VM named VM1 (redhat 7.9, java8, tomcat, apache in a DC datacenter) to a new VM named VM2 (redhat 8.7, more performance on the azure platform)

The database is oracle 19c on a redhat 7.9 on the DC

To perform the analyzes, I made a small program, with the same configuration (same driver ojdbc8-19.18.0.0.jar), which launches on the 2 VMs VM1 and VM2 and we discovered the time "SQL*Net message from client" is too large on VM2 compared to VM1

Howdy, Stranger!
