Partition Blob page warning

Hi all, I m new to informix, kindly correct me if am wrong. our environment is linux and informix version is IBM Informix Dynamic Server Version 11.50.UC6WE Recently we had a table corruption in our database, so we ran "oncheck -cDI -y datbase:schema.tablename" for that particular table, i got resolved. After that we try to check any other corruption on the entire database we ran "oncheck -cDI database". in the output log we find some warning like this on a table WARNING: partition BLOB page 0x343 in tablespace 0xd00102 appears to be more or less full than is indicated in the bitmap. Bitmap mode: 0xe, Calculated mode: 0. WARNING: The bitmap mode for page 0x343 has been reset from 0xe to 0. Cleaning up orphaned blob piece partnum 0xd00102 rowid 0x33b02 ERROR: PNBLOB piece 0x34301 referenced by datarow but not found in page can anybody tell me what is this exactly refer to and we don't have any blob dbspace created in out database. Do we have any solutions to fix this. Thanks in advance.

Hello. I think this technote might give you some help about explanations: https://www-01.ibm.com/support/docview.wss?uid=swg21675845 Even it mentions 11.70 and 12.10, the same message is returned from oncheck, so you can use the same explanations. I just want you to be aware that 11.50 is a pretty old engine, out of support, so if you want to be in safe hands, with a more secure, stable and trustable engine, you should consider an upgrade as quick as possible to a supported version. If you need some help, we are always glad to help. IIUG is a great source of knowledge, updates and tools.
