When you say bind package into a plan to make packages executable, only those executable gets stored in a plan. Can I have some programs directly bound into a plan and some programs bound into the same plan via package? Another questions - if you have mulitple programs bound directly into a plan, wh...

VSAM LDS used in DB2

Recently I learnt that DB2 uses a VSAM's Linear DS for managing the tablespace. Is this true? If True then KSDS,ESDS,RRDS are known to be a far better VSAM dataset against LDS why can't DB2 use them instead of LDS?
:roll:
