I'm having some issues when trying to connect to a remote DB2 database. The strange thing here is that sometimes it's OK but sometimes not, i.e. I cannot always reproduce this behaviour.
The error is the following:
Caused by: com.ibm.db2.jcc.am.SqlNonTransientConnectionException: [jcc][t4][10380][11951][3.64.114] Required property "<DB_NAME>" is unknown host. ERRORCODE=-4222, SQLSTATE=08001Where DB_NAME is the name of my host. The address can be resolved always using ping and nslookup. As I said, this only occurs from time to time. Does anyone know this issue? Maybe some configuration restriction on the number of active connections or X connections in a time bucket policy?

Probably, there are network issues that prevents the connection between the application (Java) and the database server, thus the database server cannot be resolved.
Please check the network to find errors.
