NOTE:

To restore an enhanced key-sequenced file (more than 16 partitions) onto a system which

only supports classic key-sequenced files (up to 16 partitions), you need to:

Restore each partition from the enhanced key-sequenced file onto the system one at a time.

Attach that partition to a temporary classic key-sequenced file to gain access to the data

records in the partition.

Copy the records from that partition to the target key-sequenced file as described in the

following procedure.

This procedure assumes you are restoring an enhanced key-sequenced (EKS) file from a source

system that is not connected to the destination system.

You need to have three temporary work volumes in addition to the volumes where the target

key-sequenced file partitions will reside.

Create the target key-sequenced file (with up to 16 partitions) with alternate key files and

partition keys to handle all of the records from the enhanced key-sequenced file being restored.

Restore each partition one at a time from the tape or a PAK file to <temp volume 1>, using

the restore partonly option.

As each partition is restored to <temp volume 1>, do the following:

Create a temporary key-sequenced file with its primary partition on <temp volume 2>

and a secondary partition on <temp volume 3>, such that its attributes match those of

the restored partition on <temp volume 1>.

Alter the temporary key-sequenced file so that the restored partition now becomes its

secondary partition, and copy the data records from that secondary partition to the target

key-sequenced file.

Alter the temporary key-sequenced file again, so that its originally created secondary

partition once again becomes its secondary partition, and delete the temporary

key-sequenced file.

You can use the following FUP commands to perform the above procedure for each restored

partition:

Set like <restored partition file>

Set part (1, <temp vol 3>, pri ext, sec ext,[0,0,0,0])

Reset partonly

Create <temp vol 2>.<subvol>.<part file>

Alter <temp vol 2>.<subvol>.<part file>, part(1, <part file name>)

Copy <temp vol 2>.<subvol>.<part file>, <target file>

Alter <temp vol 2>.<subvol>.<part file>,part(1,<temp vol 3>)

Purge <temp vol2>.<subvol>.<part file>

Purge <temp vol3>.<subvol>.<part file>
