- Terms accepted
- Indicates that an OTC license is in effect on the Db2 and that the owner accepts the terms of that license. To view the terms, see the member DSNTIPO1 of the SDSNSPFP target library for this version of Db2.
- Trackmod Implicit TS
- Determines whether Db2 tracks modifications to the pages of implicitly created table spaces.
- Max DSSIZE Implicit TS
- Determines the maximum DSSIZE in gigabytes that can be used by Db2 for creating each partition of an implicitly created base table space.
From DSN6LOGP
- Offload Option
- Determines whether online initiation of the offload process is used. Valid values: YES or NO.
- (CDDS_MODE) - (QWP2CPSY, QWP2CSRC)
The CDDS_MODE subsystem parameter specifies how a member of a Db2 data sharing group participates in a GDPS Continuous Availability with zero data loss (GDPS Continuous Availability with zero data loss) environment.
ZPARM NAME: DSN6LOGP.CDDS_MODE
Valid values are:
- NONE
- (Default) The Db2 subsystem or data sharing group does not participate in a GDPS Continuous Availability with zero data loss environment. The subsystem or data sharing group member supports only the replication of its own log. The data set that the CDDS_PREFIX parameter specifies can be defined locally but is not used.
- SOURCE
- The data sharing group that contains the member that is being installed is the source group in an implementation of the GDPS Continuous Availability with zero data loss solution. The source data sharing group supports replication of the logs and log data sets of its members by another data sharing group, which is the proxy group in the implementation of the GDPS Continuous Availability with zero data loss solution. The proxy group performs replication of tables in the source data sharing group that are enabled for changed data capture. The source group must contain a key-sequenced data set with the name that is specified by the CDDS_PREFIX subsystem parameter. That data set is the compression dictionary data set (CDDS). When IFI READS calls are made to the proxy group to retrieve compressed log records, Db2 uses the CDDS to decompress the log records. The location of the source group must be defined in the communications database of the proxy group.
- PROXY
- The data sharing group that contains the member that is being installed supports only replication of log data sets for the source data sharing group in an implementation of the GDPS Continuous Availability with zero data loss solution. The location of the proxy group must be defined in the communications database of the source group.
- (CDDS_PREFIX) - (QWP2CDDS)
The CDDS_PREFIX subsystem parameter specifies the prefix for the name of the data set that contains dictionaries that Db2 uses to decompress compressed log records when a proxy data sharing group in an implementation of the GDPS Continuous Availability with zero data loss (GDPS Continuous Availability with zero data loss) solution captures the log records on behalf of a source data sharing group. The data set is known as the compression dictionary data set (CDDS).
The data set name is formed by appending the string '.CDDS' to the value of CDDS_PREFIX.

- The Db2 database manager does not materialize the result of a user-defined SQL table function that is defined as NOT DETERMINISTIC.
- YES
- The Db2 database manager materializes the result of a user-defined SQL table function that is defined as NOT DETERMINISTIC. Use this setting to avoid errors in processing SQL statements that reference those user-defined SQL table functions
- (MOVE_TO_ARCHIVE_DEFAULT) - (QWP4MTAD)
- Specifies the default for the SYSIBMADM.MOVE_TO_ARCHIVE built-in global variable.
ZPARM NAME: DSN6SPRM.MOVE_TO_ARCHIVE_DEFAULT
Valid values are:
- N
- (Default) Specifies that a delete of a row in an archive-enabled table will not result in storing a copy of the deleted row in the associated archive table.
- E
- Specifies that a delete of a row in an archive-enabled table will result in storing a copy of the deleted row in the associated archive table.
- Y
- Specifies that a delete of a row in an archive-enabled table will result in storing a copy of the deleted row in the associated archive table. Additionally, when the global variable is set to 'Y', an insert or update operation that specifies the archive-enabled table as the target of the statement will result in an error.
- (DISALLOW_SEL_INTO_UNION) - (QWP4DSINUN)
- Specifies whether to disallow a UNION or UNION ALL as the outermost from-clause of a SELECT INTO
statement, which is invalid SQL syntax. Such statements were inadvertently allowed before Db2 12.
However, in Db2 12 they are disallowed by default.
Online changeable: YES
ZPARM NAME: DSN6SPRM DISALLOW_SEL_INTO_UNION
Valid values are:
- YES
- (Default) SELECT INTO statements with UNION or UNION ALL as the outermost from-clause are not supported. This setting enforces valid SQL syntax.
- NO
- SELECT INTO statements with UNION or UNION ALL as the outermost from-clause are accepted. This setting tolerates invalid SQL syntax.
- (COMCRIT) - (QWP4COMC)
- Sets the Common Criteria environment, which requires that tables that you create (other than
created global temporary tables, declared global temporary tables, and auxiliary tables) must have
multilevel security.
ZPARM NAME: DSN6SPRM.COMCRIT
Security parameter: YES
Valid values are:
- NO
- (Default) The behavior of Db2 is unchanged.
- YES
- All tables that you create (other than created global temporary tables, declared global temporary tables, and auxiliary tables) must have multilevel security. If the AS SECURITY LABEL clause is missing from a table, an error occurs and the table is not created. Setting COMCRIT to YES causes some of the current installation and migration processes to fail. A value of YES also limits the number of concurrent sessions that are allowed for a primary authorization ID if a RACF custom field is defined for that ID.
- (ENCRYPTION_KEYLABEL) - (QWP4ENKL)
- The ENCRYPTION_KEYLABEL subsystem parameter specifies the name of an ICSF key label to provide
to DFSMS when using z/OS DFSMS data set encryption support to define encrypted data sets for the Db2
catalog, directories, and archive logs. The setting is used to define encrypted data sets for the
Db2 catalog, directory objects, user-defined indexes on the catalog, and archive logs only when the
Db2 function level is V12R1M502 or higher. The default setting of blank means Db2 does not provide
the key label during allocation of the data sets associated with the system objects. If non-blank,
ENCRYPTION_KEYLABEL must be set to a string from 1 - 64 bytes that identifies a protected data key
in the ICSF key repository. A change to this parameter does not take effect until you use the -SET
SYSPARM command to bring it online. Even if you start or restart Db2 after changing the value, the
change is not honored until you issue the -SET SYSPARM command. In Db2 data sharing, all members
need to use the same setting. When changing the setting of ENCRYPTION_KEYLABEL for a data sharing
group, make the change on all members before running the -SET SYSPARM command on any member.
Acceptable values: 1 - 64 bytes.
Default: Blanks
