I have a question about quiescing a table. The command refers to a table but the whole tbspce is quiesced. Am I interpreting something wrong? Also, how to unquiesce?

db2 "quiesce tablespaces for table tabschema.tabname exclusive"

Is there a way to quiesce a table and not a tablespace?

Thanks

No. Only if you put just one table in the tablespace.

At the DB2 "implementation" level (logs, backups, quiesce, ...) there are just tablespaces, no tables.

db2 quiesce tablespaces for table tabschema.tabname reset

See e.g. page 316 of the Utilities Guide:
The "quiesce" action --taken by utilities like e.g. LOAD or REORG-- is also known as a "claim & drain" action (terminology used on DB2 for z/OS), since it drains out all "normal" tablespace locks while the claim prevents other "normal" locks to be taken in the meantime.
In contrast with "normal" locking, quiesce is a "persistent" way of locking a tablespace, since it is not released at e.g. disconnect, commit, or rollback. Only a "quiesce reset" can release it.

Thanks for the info.
