Informix Error -23548: CM error: This would create two chunks with the same name and offset

Cause and resolution

CM error: This would create two chunks with the same name and offset

You have issued a command to the CM system that tries to create two chunks that have exactly the same name and offset. This happens most commonly when you create chunks on different coservers (you might want to use "%c" formatting).

Examine your command and re-issue it so that the two chunks have distinct names.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-23548 fires when a CM command would create two chunks with exactly the same name and offset — per the official guidance, most commonly when creating chunks across different coservers.

  1. A chunk-creation command producing an identical name/offset on multiple coservers, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Re-issue the command with distinct chunk names, per the official guidance — consider using %c formatting to vary the name per coserver.
Examples
N/A

No specific triggering statement is documented beyond identical name/offset across coservers.

Diagnostic Checks
  1. Check the chunk name/offset being applied across coservers, and use %c formatting or otherwise vary the name.

  • -23507 — "CM error: Chunk already exists." The general chunk-collision error this is a specific case of, for identical name and offset.
  • -23547 — "CM error: This would create two chunks that would overlap each other." A related overlap error, on chunk placement rather than identical name/offset.

A chunk-creation command would produce two chunks with the same name and offset — vary the name, e.g. with %c formatting.
