Hi

the shared sort heap threshold is a paramter that sets the amount of memory available for sort operations, i never saw the message you describe, but you can start off be check the value of that parameter

and about the attentions, i guess it means you need to run a reorg on the listed tablespaces
do you have any threshholds defined in the health center ?

hi

i could not find dbtb_reorg_req anywhere so i guess it's a threshold that someone defined in your site using the health center, can you check this issue ?

the shared sort heap threshold is a database parameter which you can see by doing:
db2 get db cfg for <database name> and looking at the value for sheapthres_shr. The value that has been configured is only used if:
if the intra_parallel database manager configuration parameter is set to yes, because when intra_parallel is set to no, there will be no shared sorts.
if the Concentrator is on (that is, when max_connections is greater than max_coordagents), because sorts that use a cursor declared with the WITH HOLD option will be allocated from shared memory.
So if that is your case, you have to allocate some memory to this parameter to avoid getting this message, or, turn off the alarm in the Health Center.
dbtb_reorg_req
DB.Salary
DB.Salaryx
DB.Salaryxx
DB.Salaryxxx
means reorganzie those tables or again, if you dont want to reorganize the tables, turn off the alarm in the Health Center
