Why auto reorg is failing with SQL0284


Auto  reorg  is enabled.

But,  it's  failing with  SQL0284 messages in the db2diag.log  similar to following,


2016-03-02- I4469422E526          LEVEL: Error
PID     : 11111                TID : 46912895825555  PROC : db2acd 0
INSTANCE: db2inst1              NODE : 000            DB   :  testdb1
APPID   : <appid>
HOSTNAME:  db2host1
FUNCTION: DB2 UDB, Health Monitor, db2HmonEvalReorg, probe:997
MESSAGE : Failed to evaluate table "MYSCHEMA "."MYTAB1".
Probe 535 .
          SQLCODE = -284
DATA #1 : Hexdump, 4 bytes
0x00002AAAC27D8CCC : E4FE FFFF         


SQL0284N  Table creation failed because the table space
      "<tablespace-name>" that was specified in the statement after the
      clause "<clause>" is not a supported type of table space for that
      clause. Table space type: "<tablespace-type>".


The reason of the failure being the  SYSTOOLSTMPSPACE  is defined  incorrectly.

If this tablespace is defined  with type/Content  anything other than user  temporary tablespace  the auto reorg will face this issue.


Need to recreate the same tablespace  following the guideline in this page  to  fix the problem,
