EXTRACT (Extract Data Table) › Parallel Extract › Restrictions

Restrictions

We do not recommend parallel extract for tables with a NATIVE sequence key defined as descending or as being type sensitive. For these types of keys, the actual key value stored in the index may differ from the value stored in the data row. Parallel extract is therefore allowed with the restriction that the key value provided must be in the internal index format, not in the external format matching the data row data.

Other restrictions for parallel extract are as follows:

• The option is available only in z/OS.
• The option is available only to EXTRACT with SEQ=NATIVE and AREA= specified.
• Exercise due caution when specifying and using parallel extract. Be aware that data rows could be lost due to poorly defined control statements or data set handling. CA Datacom/DB cannot edit the goal, only the specific control statements provided.
