Informix Error -9485: Attempt to install an existing jar: (%s).

Reasons / Common Causes

-9485 fires when install_jar() is called with a name that's already in use — per the official guidance.

1. A jar name collision with an already-installed jar, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Remove the existing jar before installing a new one with the same name, per the official guidance.

Examples

Reinstalling over an existing jar

EXECUTE PROCEDURE remove_jar('MyJar', 0);
EXECUTE PROCEDURE install_jar('file:/path/to/myjar.jar', 'MyJar', 0);

Diagnostic Checks

1. Check whether a jar with the target name already exists, and remove it first if replacing it.

• -9487 — "Attempt to remove non-existing jar: (%s)." The inverse case — removing a name that doesn't exist.

The jar name is already in use — remove the existing jar first.
