DB2 tablespace

Question

Dear All,
May I know the proper way to increase a tablespace? Should change the tablespace from transaction DB02 from SAP login or I should update in the DB2 control center?
Currently, my system is generating some abap dumps which is caused by some tablespace is almost full.
Will also really appreciate it if someone can guide me to update the tablespace.
Regards,
John

If you are out of space in you tablespaces but not out of space in your sapdatas then you can either manually extend the size of the containers or setup Auto-resize.
There are various ways to setup Auto-resize..  I usually do a list tablespaces and pipe that to a file, then write  an inline ksh to issue the alter TS statement while reading through the file.
If you are out of space in your sapdata's then you can either increase the lun size, if your san allows this, or add additional sapdata's and containers.
In adding addtional containers, my preferred method is to add another sapdata and go through rebalancing.  keeping all new containers the same size as the old containers
Also be aware you can shrink tablespaces that have a large amount of free space and free up space in  your sapdatas as well.  Of course if your HWM is artifically high this requires more work.
