Informix Error -9455: Cannot access large object.

Reasons / Common Causes

-9455 fires when a large object can't be accessed — per the official guidance.

1. The default sbspace not yet created, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Make sure the default sbspace, named by the SBSPACENAME configuration parameter, has been created, per the official guidance — use the onspaces utility to create it.

Examples

Creating the default sbspace

$ onspaces -c -S sbspace1 -p /path/to/chunk -o 0 -s 100000

Diagnostic Checks

1. Check SBSPACENAME in ONCONFIG and whether that sbspace actually exists (onstat -d), and create it with onspaces if missing.

A large object couldn't be accessed because the default sbspace doesn't exist — create it with onspaces, matching SBSPACENAME.
