Informix Backups Error Message

Informix Backups Error Message

Question:
We have Informix IDS 7.30 running under SCO 5.0.5. Backups by ontape fail with an error: “I/O read chunk 90, pagenum 2, pagecnt 1 –> errno = 9″But when we are doing normal queries, it’s all fine. Any ideas?

Answer:
First, I’d run oncheck against the reserved pages and system pages to see if anything’s getting reported here. Find out what your OS’s Error 9 means. The error number most probably comes from the OS, and this may tell you what’s happening.
