Hi All.
This is an ORDS / Apex installation.
ORDS: ords-23.3.0.289.1830
Apex is version 23
Oracle Database is 19c under Windows (pluggale DB).
I'm ocassionally getting Net Errors (not specifically related to ORDS / Apex, which BTW is running under Tomcat 9).

Like I said I´m suspecting this may not be specifically related to ORDS and Apex. For example I´ve gotten net errors during impdp operations (ocassionally).
Also found this type of errors on alert.log:

However, as you can see on the screenshot above, we may be hitting the maximum number of sessions in the pool. So I would like to know:
- How to query the actual value for connection pool used by ORDS.
- How to increase that value.
Thanks so much in advance !!!
