Hi ,
I have created a VRRDS file with following attributes:
Average record size 5
Maximum record size 600
Share options 3,4
Buffer space 7168
CISIZE Unit Prim Sec
Data 2048 CYLS 50 20
Index 3072 CYLS 50 20
The problem is while I am copying the VRRDS file to another vb sequential file,it's running for long time.
But when I am copying an RRDS(fb format) with almost same attributes as VRRDS file to vb sequential file with same record counts,it's running fine.
Number of records is in the range of 2.5 millions.
Can anyone throw some light on it? |

Hi ,
The issue is solved when I changed the attributes of the VRRDS file.
So the changed attributes are now as follows:
Average record size 5
Maximum record size 600
Share options 3,4
Buffer space 13312
CISIZE Unit Prim Sec
Data 6144 CYLS 50 20
Index 1024 TRKS 1 5
So I think the problem was due to buffer space which is now maximum.and CISIZE.
Thanks.. |

Since you've actually used the MINIMUM buffer space allowed (two times the data CI size plus index CI size), I don't think you can say that you're using the maximum, and I definitely don't think you can say that your problem was caused by your buffer space -- since you had 2 times data + index before and you have 2 times data + index after.
More to the point, RRDS does not have an index component. If you have an index component, you are not working with a NUMBERED (RRDS) VSAM file. I'm not sure what you are working with, why you had your problem, or how it was resolved -- but the data you've presented is not consistent and does not match what you are saying. |

Damnedably good spot Robert, Index portion for an RRDS.
It can only be a KSDS he's on about. |
