-930 Cannot connect to remote host sitename.

Informix STAR or IBM Informix NET is trying to access another computer system but has failed. Note the site name in the current statement. Contact your network administrator, and ask for a check that the network is operational and that the particular site is active. This message appears in database servers prior to Version 6.0.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-930 fires when the application fails to reach another computer system — per the official guidance, this is a general connectivity failure, with the network administrator and DBA jointly responsible for checking network operability and the specific server's active status.

  1. The network not operational between the client and the target server, per the official guidance.
  2. The specific target database server (or, pre-6.0, site) not active, per the official guidance.
Solutions / Resolution
  1. Note the server (or, pre-6.0, site) name in the current statement, per the official guidance, to identify exactly which target failed.
  2. Ask your network administrator and DBA to check that the network is operational and that the particular database server is active, per the official guidance — this is a joint network/DBA diagnostic, not purely one or the other.
Examples
Identifying the specific target
-- Review the statement that produced -930 for the exact server/site
-- name it referenced, to give the network administrator and DBA a
-- specific target to check.
Diagnostic Checks
  1. Identify the exact server/site name from the failing statement.
  2. Escalate jointly to the network administrator (network operability) and DBA (server active status), per the official guidance.
Related Errors / Related Topics
  • -908 — "Attempt to connect to database server (servername) failed." A closely related connectivity error, with essentially the same underlying causes and resolution path.
  • -907 — "Cannot create socket on current database server." A related connectivity error, about the local system's TCP/IP rather than the remote target.

A general connectivity failure — identify the exact target and escalate jointly to the network administrator and DBA, per the official guidance.
