TRIDEX – Tri-State Db2 Technology Exchange in New York, NY, USA

SEGUS & SOFTWARE ENGINEERING present:
Db2 for z/OS Know your Limits!
In this presentation I will show and explain the current number of limits within Db2 on z/OS.
Starting with relatively basic simple things like DSSIZE or PIECESIZE. Moving on to Linear Dataset limits (32 for segmented spaces, 254 for LOB). We then will have a quick look at how the COPYPOOL is looking before diving off to the world of PBGs, where you must be aware of MAXPARTITONS among other things. Then we will review SEQUENCES and Numeric Primary Key usage before finally delving into the abstract limit of Db2 within the Db2 engine including DBATs etc.
