U02000358 Unable to resolve ip address '<servername>:2218' given from CP during CP selection. Error: 'The name does not resolve for the supplied parameters. >InetAddress.cpp#net::InetAddress::getAddrInfoLogged(const char *, const char *

Resolution

For some reason, the agent is not able to resolve the hostname of the host and crashes.

The workaround consists of populating either Host file or DNS with Hostame and IP of the system. To add a new entry into the host file instruction ADDTCPHTE can be used. 

Additional Information

The same problem with the AS400 agent can encountered with following error message appearing in the logs:

20230801/093118.723 - U02000360 Agent 'PCA' has been started with process ID 'UC4AGENT'.
20230801/093118.798 -           Unable to determine hostname: reason 'The name does not resolve for the supplied parameters. >InetAddress.cpp#net::InetAddress::getAddrInfoLogged(const char *, const char *, int, int, int):834<'.
20230801/093118.977 -           Unexpected exception occured, Agent forces a trace.

Reason : The Hostname of the AS 400 is not correctly defined either in the internal system configuration or on DNS level:

Actions to verify these settings can be one of the two:

The content of Host table entries confirming the host name

Command CFGTCP ==> option 10 (Work with TCP/IP host table entries)

On the AS400 system enter the Unix interface of this AS400 host (command 'QSH')

What does the instruction 'hostname' return?
