FASTGENR Frequently Asked Questions |
| Below are some common questions asked by prospective users of FASTGENR. If you have further questions, or need further information on the below questions please contact us. |
 |
Does FASTGENR support all IEBGENER commands and functions? |
|
| A: Yes, FASTGENR supports all IEBGENR commands and functions. Additionally FASTGENR offers it's own set of productivity and data-integrity features over FASTGENR. |
 |
|
|
How much faster can FASTGENR copy sequential datasets over IEBGENER? |
|
| A: In most cases FASTGENR will copy sequential datasets 50% to 95% faster than IEBGENER. The larger the dataset, the larger the savings you can obtain by using FASTGENR. Regardless of dataset size, FASTGENR offers added value through its useful diagnostic information, expanded printout and enhanced copy features that significantly improve data reliability and programmer productivity. |
|
|
|
Are JCL changes required to implement FASTGENR? |
|
| A: No, FASTGENR is completely JCL transparent. |
|
|
|
Does FASTGENR support large tape blocksizes (over 32K)? |
|
| A:Yes, as of release 2.6 FASTGENR supports large tape blocksizes up to 256K. Large tape blocksize support relaxes the traditional maximum limit blocksize of 32K for tape devices and takes advantage of the higher capacity drives. |
|
|
|
What DASD types is FASTGENR compatible with? |
|
| A: FASTGENR is compatible with all IBM supported CKD DASD devices including ESCON, RVA and SHARK. |
|
|
|
How is FASTGENR installed? |
|
| A: There are 4 ways FASTGENR can be installed: FASTINIT, RENAME, SMP - SMP/E or Stand Alone. The FASTINIT install; which is the preferred method of installation, enables FASTGENR to intercept all uses of IEBGENR without moving, renaming or altering the IBM-supplied modules. FASTINIT is totally transparent to, and will not disrupt, normal IBM SMP/E maintenance procedures. The RENAME install requires that the original IEBGENER module be renamed to OLDGENER and then FASTGENR frontend renamed to IEBGENER. You can use the IBM SMP or SMP/E routines to apply a usermod; which re-linkedits IEBGENER and adds one CSECT, the FASTGENR frontend. |
