Informix Error -9200: Purpose routine (am_xxx) is not yet supported with JVTI.

Reasons / Common Causes

-9200 fires when JVTI (Java Virtual-Index Interface) code includes a purpose method not supported in this release — per the official guidance.

1. A purpose routine of am_delete, am_insert, am_update, am_check, am_truncate, or am_stats, per the official guidance — these am_xxx methods are named as unsupported with JVTI.

Solutions / Resolution

1. Remove or avoid implementing the unsupported purpose routine in the Java access method, per the official guidance's implication.
2. Use the C-language Virtual-Index Interface instead if the unsupported routine is required, consistent with the general JVTI feature-coverage limitation documented for this subsystem (see -9201).

Examples

N/A

No specific triggering statement is documented beyond implementing one of the named unsupported am_xxx methods in a JVTI access method.

Diagnostic Checks

1. Check the Java access method's implemented purpose routines against the unsupported list (am_delete, am_insert, am_update, am_check, am_truncate, am_stats).

Related Errors / Related Topics

• -9201 — "Secondary access method with Java am_purpose routine is not supported." A related JVTI feature-coverage limitation, on secondary access methods rather than specific purpose routines.
• -9202 — "JVTI only supports external am_sptype in this release." A related JVTI feature-coverage limitation, on storage type rather than purpose routines.

A JVTI purpose routine (am_delete/am_insert/am_update/am_check/am_truncate/ am_stats) isn't supported in this release — avoid implementing it in Java, or use the C-language interface.
