DB2 FOR LUW / DB2FORLUW / A10 - DB2

Load command fails with SQL0902C with reason code 85, when there 
is an index with key length (which is based on size of index 
columns plus some internal overhead) of around 4000 or around 
8100 bytes.  There is a "Sort reclen limit exceeded" error 
message in db2diag.log like this:

MESSAGE : Sort reclen limit exceeded 
 
DATA #1 : String, 156 bytes 
 
Sort.  In function sqlsTableInfoSetup( ) Line 800 
 
Record length exceeds 4005 -- the maximum allowed for this 
temporary 
tablespace. 
 
Sort record length 4013 
 
 
This is caused by mismatched LOAD internal logic -- LOAD first 
determines that we can use 4K / 8K page size (respectively) 
temporary tablespace for index sorts, then later discovers that 
we need larger page size temp tablespace. 
 
A sample scenario: 
 
>CREATE TABLE tab1  ( "ID" INTEGER NOT NULL , "VALUE" 
VARCHAR(4000) NOT NULL ) 
>CREATE INDEX inx1 ON tab1 ("VALUE" ASC)ALLOW REVERSE SCANS 
 
>db2 load from data.del of del replace into tab1 nonrecoverable 
 
SQL0902C  A system error (reason code = "85") occurred. 
Subsequent SQL 
statements cannot be processed.

Modify the table and/or index definition and increase some 
column size slightly so that the index key length exceeds ~4000 
or ~8100 bytes.  Due to internal overhead that varies with 
different configurations, one may need to do some 
trial-and-error tests to find the specific increments needed to 
avoid the problem.

DB2 Version 10.1 Fix Pack 3 for Linux, UNIX, and Windows
