hello,

i have an issue on my prod server since lastweek.
from server.log i got this message error but i have no idea where the problem is.
im using Integration Server 10.15 and ojdbc8

error message:
1.
[1787]IO Error: Got minus one from a read call, connect lapse 60017 ms., Authentication lapse 0 ms.
[1786][ADA.1.204] Cannot connect to the database with DataSource class “oracle.jdbc.pool.OracleDataSource”.

Integration Server is connected to many Oracle DB but this error only appear from 1 DB. what i suppose to do?

Hi Momon,

what is the exact version of your ojdbc8.jar? To which Oracle version is it referring?
Which Oracle version is the affected database running on?
I assume that your are running on JDBC Adapter 10.3.
Are there any fixes applied to IS, ART and JDBC adapter?
Can you get in contact with the DBAs of the affected DB to check if there is anything related to this in the logs on DB side?

Were there any changes on IS or DB side which might be causing this?

Regards,
Holger
