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.
Defaults: The default for an option is the value used if you omit the entire option.
- A default of plan value for BIND PACKAGE means that the default is the same as the value determined during the bind or rebind of the plan to which the package is appended at run time.
- A default of existing value for REBIND PLAN or REBIND PACKAGE means that the default is the value that was determined during the previous bind or rebind of the plan or package that you are rebinding.
Catalog records: The DB2® catalog records information about plans and packages, chiefly in the tables SYSIBM.SYSPLAN and SYSIBM.SYSPACKAGE. The descriptions of where the options record information omit the constant qualifier, SYSIBM, of those table names.
For all other cases, the option descriptions note the specific defaults, which DB2 assigns at bind time. If a specific default value exists, that value is underlined.
- ACQUIRE bind option
The ACQUIRE bind option specifies
that resources for the packages in the plan are to be acquired when
the application first accesses them. - ACTION bind option
The ACTION option determines whether the object (plan or
package) replaces an existing object with the same name or is new. - APCOMPARE bind option

when access paths of the old copy are identical to the incoming copy. - APREUSE bind option
The APREUSE option specifies whether DB2 tries to
reuse previous access paths for SQL statements in a package. DB2 uses
information about the previous access paths from the directory to create
a hint. - ARCHIVESENSITIVE bind option
The ARCHIVESENSITIVE option determines whether references to archive-enabled tables in
both static and dynamic SQL statements are affected by the value of the SYSIBMADM.GET_ARCHIVE global
variable. - BUSTIMESENSITIVE bind option

to application-period temporal tables in both static and dynamic SQL
statements are affected by the value of the CURRENT TEMPORAL BUSINESS_TIME
special register. - CACHESIZE bind option
The CACHESIZE option determines the size (in bytes) of
the authorization cache acquired in the EDM pool for the plan. - COLLID bind option
The COLLID option specifies that any DBRMs in the plan
are to be bound to packages. - CONCURRENTACCESSRESOLUTION bind option

access resolution option to use for statements in a package. - COPY bind option

package. - CURRENTDATA bind option

currency for read-only and ambiguous cursors when the isolation level
of cursor stability is in effect. It also determines whether block
fetching can be used for distributed, ambiguous cursors. - CURRENTSERVER bind option

a query using parallel processing to maximize performance. - DEPLOY bind option
The DEPLOY option deploys
a non-inline SQL function or a native SQL procedure. - DESCSTAT bind option

when binding static SQL statements. - DISCONNECT bind option
The DISCONNECT option determines which remote connections
to destroy during commit operations. - DYNAMICRULES bind option
The DYNAMICRULES option determines the rules that apply
at run time for certain dynamic SQL attributes. - ENABLE and DISABLE bind options
The ENABLE and DISABLE options determines which connections
can use a plan or package. - ENCODING bind option
The ENCODING option specifies the application encoding
for all host variables in static statements in a plan or package. - EXPLAIN bind option
The EXPLAIN option causes the bind
process to obtain information about how SQL statements in the package
or packages are to execute. - EXTENDEDINDICATOR bind option
The EXTENDEDINDICATOR option determines whether DB2 recognizes extended indicator
variables when the associated package is run. - FILTER bind option
The FILTER option lets you delete a set of queries in the
SYSIBM.SYSQUERY table under a {tag} value that is specified by the
SYSQUERY.USERFILTER column. - FLAG bind option
The FLAG option determines the messages to display during
the bind process. - GENERIC bind option
The GENERIC option specifies one or more bind options that
are supported by the target server, but are not supported as options
for BIND PACKAGE or REBIND PACKAGE on the DB2 for z/OS® subsystem
on which the BIND or REBIND command is issued. - GETACCELARCHIVE bind option
The GETACCELARCHIVE bind option specifies whether a static
SQL query that is bound for acceleration retrieves archived data on
the accelerator, instead of active data. - IMMEDWRITE bind option
The IMMEDWRITE option indicates whether immediate writes
are to be done for updates that are made to group buffer pool dependent
page sets or partitions. - ISOLATION bind option
The ISOLATION option determines how far to isolate an application
from the effects of other running applications. - KEEPDYNAMIC bind option
The KEEPDYNAMIC option determines whether DB2 keeps dynamic SQL statements after commit points. . - LIBRARY bind option
The LIBRARY option determines what
partitioned data set or zFS file path to search for the DBRM that
is listed in the MEMBER option. - MEMBER bind option
The MEMBER option determines
what database request modules (DBRMs) to include in the package. - OPTHINT bind option
The OPTHINT option controls whether access paths that are
specified in PLAN_TABLE instances are used for static SQL statements. - OPTIONS bind option
The OPTIONS option specifies which bind options to use
for the new package when the COPY option is specified. - OWNER bind option
The OWNER option determines the authorization ID of the
owner of a plan or package. - PACKAGE bind option
The PACKAGE option determines the packages to bind or rebind. - PATH bind option
The PATH option determines the SQL path that DB2 uses to resolve unqualified stored procedure
names in CALL statements, in user-defined data types, and in functions. - PATHDEFAULT bind option
The PATHDEFAULT option resets the
PATH value for a package or plan to SYSIBM, SYSFUN, SYSPROC, SYSIBMADM, plan
qualifier, or to SYSIBM, SYSFUN, SYSPROC, SYSIBMADM, package
qualifier . - PKLIST and NOPKLIST bind options
The PKLIST option determines the packages to include in
a package list. The NOPKLIST option deletes packages from a package
list. - PLAN bind option
The PLAN option determines the plan or plans to bind or rebind. - PLANMGMT bind option
The PLANMGMT option retains, during a rebind operation,
all relevant package information (such as metadata, query text, dependencies,
authorizations, and access paths) in catalog tables and in the directory. - PROGAUTH bind option
The PROGAUTH option specifies whether DB2 performs program authorization checking to

a plan. - QUALIFIER bind option
The QUALIFIER option determines the implicit qualifier
for unqualified names of tables, views, indexes, and aliases contained
in the plan or package. - QUERYACCELERATION bind option
The QUERYACCELERATION bind option specifies whether a static
SQL query is bound for acceleration, and if so, with what behavior. - QUERYID bind option
The QUERYID option frees entries in the SYSIBM.SYSQUERY
table, and the SYSIBM.SYSQUERYPLAN table or the SYSIBM.SYSQUERYOPTS
table. - RELEASE bind option
