WORKDDN

For more information about these data sets, see SYSUT1-data-sets-in-LOADPLUS.

If you use this command option to override the default name in the installation options module, you must also change the ddname in your JCL.

DSNUTILB load jobs

When invoking DSNUTILB, LOADPLUS uses this option only to pass a value for the &DDNAME variable for the data set name pattern. LOADPLUS includes this information in the TEMPLATE control statement that it builds for the IBM DB2 LOAD utility.

Multiple data sets

If you use multiple work data sets, specify only the ddname prefix (no nn) in this option. Note the following considerations:

• If you are not dynamically allocating work data sets, you must append nn to the ddnames in the DD statements in your JCL, where nn can be one or two valid alphanumeric or national characters. These ddnames must not exceed eight characters.
• If you are not dynamically allocating work data sets, the prefix must allow LOADPLUS to differentiate it from any ddnames that you specify in your JCL for other data sets. For example, if you specify a WORKDDN prefix of SYSR and your JCL contains a DD statement for your input data set that uses a ddname of SYSREC, LOADPLUS assumes that the SYSR prefix refers to the SYSREC data set.
• When you dynamically allocate SYSUT1 data sets, LOADPLUS appends the data set number to the ddname prefix that you specify. To dynamically allocate more than 99 SYSUT1 data sets, use this option to specify a ddname prefix. The prefix plus the highest data set number must not exceed eight characters. For more information, see Specifying ddname prefixes.
• If dynamic data set allocation is active and you specify more than one ddname prefix for dynamic allocation, the prefix for each ddname must be different enough for LOADPLUS to differentiate one prefix from another. To be different enough, if these prefixes are different only because one prefix has additional trailing bytes, then these trailing bytes must contain at least one nonnumeric byte. For example, the first set of prefixes that follow is different enough, but the second set is not:

  • Acceptable set:

    BMCRD
    BMCRDWK

  • Unacceptable set:

    BMCRD
    BMCRD11

Specifying the default

You can specify the default for the WORKDDN command option in your installation options module by using the WORKDDN installation option. LOADPLUS was shipped with a default value of SYSUT1 for this option. The command option overrides the default that is in the installation options module.
