Features and Benefits
VSAM Quick Index delivers:
| Features | Benefits |
|---|---|
| High-performance alternate index creation | Builds indexes faster than IDCAMS BLDINDEX, and builds multiple alternate indexes while reading the base cluster only once. |
| Utilizes your house sort utility | Utilize your existing sort utilities such as IBM DFSORT, Syncsort MFX, or CA Sort for z/OS without the need to get an additional sort utility. This prevents the need to buy, install, and learn an additional utility. |
| Creates multiple alternate indexes with a single pass of the base cluster | VSAM Quick Index requires customers to create minimal JCL, without the need to specify all the names of the alternate indexes for the base cluster. Furthermore, VSAM Quick Index can automate the process of calculating and allocating the optimal buffers for better performance. |
| Develops alternate keys from non-contiguous portions of base records | Allows you to build alternate index keys from non-contiguous areas of data while limiting the number of non-unique pointers. |
| Omits meaningless alternate keys dynamically | Generic and fully qualified key values, such as blanks, zeros, and prefix codes, may be excluded from the build process. |
