DB2 and related commandsThe references topics for commands contain syntax diagrams, semantic descriptions, rules,
and usage examples of commands. They are organized alphabetically by command name.
ABEND (DSN) -ACCESS DATABASE (DB2) The DB2 command ACCESS DATABASE forces a physical open of a table
space, index space, or partition, or removes the GBP-dependent status for a table space, index
space, or partition. The MODE keyword specifies the action taken. -ALTER BUFFERPOOL (DB2) The DB2 command
ALTER BUFFERPOOL alters attributes for active or inactive buffer pools.
Altered values are used until altered again. -ALTER GROUPBUFFERPOOL (DB2) The DB2 command
ALTER GROUPBUFFERPOOL alters attributes of group buffer pools. -ALTER UTILITY (DB2) The DB2 command
ALTER UTILITY changes the values of certain parameters of an execution
of the REORG utility that uses SHRLEVEL REFERENCE or CHANGE and the
REBUILD utility that uses SHRLEVEL CHANGE. -ARCHIVE LOG (DB2) The DB2 command
ARCHIVE LOG enables a site to close a current active log and open
the next available log data set. BIND PACKAGE (DSN) The DSN subcommand BIND PACKAGE builds an
application package. DB2 records
the description of the package in the catalog tables and saves the
prepared package in the directory. BIND PLAN (DSN) The DSN subcommand BIND PLAN builds an application
plan. All DB2 programs require
an application plan to allocate DB2 resources
and support SQL requests made at run time. BIND QUERY (DSN) The DSN subcommand BIND QUERY reads the statement text, default schema, and a set of
bind options from every row of DSN_USERQUERY_TABLE, and information from correlated EXPLAIN table
rows.DB2 inserts the pertinent data into certain catalog tables. BIND and REBIND options for packages and plans There are several options you can use for
binding or rebinding plans and packages. Some of the options are common
for both bind and rebind and for both plans and packages. Specification of DB2 for z/OS bind options from IBM Data Server clients and drivers DB2 for z/OS data
servers from IBM Data Server
clients and drivers, you need to specify bind options that are supported
by DB2 for z/OS but
not by DB2 for Linux, UNIX, and Windows as
generic bind options.-CANCEL THREAD (DB2) The DB2 command CANCEL
THREAD cancels processing for specific local or distributed
threads. /CHANGE (IMS) The IMS™ command
