Hello expert,
Regarding table SXMSCLUR and SXMSCLUP, there are a lot of blog and notes on it.
Most of them are talking on using a program to delete surplus data,or archive,deletion job.
The notes give solution to delete table content,but it didn't explain the reason.
Deletion and archive jobs iwill delete message,but it seems no jobs will delete content of SXMSCLUR and SXMSCLUP.
In recent days,we met a issue related to these two tables.
DBA found one of our table-space increased quickly in recent days,in DB02 we found the remarkable increase were in table SXMSCLUR and SXMSCLUP and related SYS_LOB0000$$ table.
We checked our regular deletion program:
RSXMB_DELETE_MESSAGES
RSXMB_TABLE_SWITCH
RSXMB_DELETE_HISTORY
They ran normally everyday.
We don't understand why the content of SXMSCLUR and SXMSCLUP increase so quickly after a certain date?
Actually,we didn't find remarkable increase of SXMSCLUR and SXMSCLUP before that date.
Is there any auto housekeeping mechanism to clean the table content, and it is easy to break?
Pls help.
Thanks.
