database - DB2 linking schemas across multiple instances -

-

i have few instances of db2 10.5 server running on 1 physical linux machine, let name them inst1 , inst2.

all of them contain multiple schemas, schema-naming unique accross whole machine, example inst1_schema_a, inst2_schema_a etc.

what somehow create user can access of schemas on 1 instance, possible make queries like: select id inst1_schema_a union select id inst2_schema_a

how can achieve that? should link databases , alias schemas?

federation

is keyword request. db2 luw db2 luw included in license , done across multiple databases - not matter if reside within same instance, instance on same server or different server.

set federated = yes in dbm cfg, define server , set nicknames remote tables. details refer article or one or ibm knowledge center.
