IDMS error status 0811 when running Restructure to DECOMPRESS a record

Issue/Introduction

Wanted to remove compression from a record, but the Restructure received 0811, indicating that there was not enough space in the area to decompress the record.

Resolution

The client ran Unload-Reload to do both, enlarging the area's page range and remove the compression.
The original schema/subschema  (which already specifies the dct BUILTIN for COMPRESSION and DECOMPRESSION), will allow Unload to decompress the records that it reads, and the RELOAD will use the new subschema that does not specify any compression routine, so the Reload will store the records into the new page range without compression. 

The database should be verified after the Reload with the PRINT SPACE utility along with an application to verify that the records are accessible with the new subschema.
