Producing image copies

For efficiency, BMC AMI Reorg might initiate an extra copy server. This server job functions solely to produce image copies from objects that have been already reorganized and completed.

In addition to the syntax options described in REORG-TABLESPACE-syntax-diagrams, you can use the following controls.

Important

BMC AMI Reorg supports only dynamic allocation of copy data sets. If you specify copy DD statements in your JCL, BMC AMI Reorg ignores them.

Global parameters	The following global parameters enable you to control copy processing: FLASHCOPY enables you to specify whether FlashCopy image copies are required or preferred. SVRSPECIAL controls special server processing for image copies.
NGTTAPE command	The NGTTAPE-command passes tape unit allocation data to BMC AMI Reorg.
OUTPUT command	The OUTPUT-command-for-BMC-AMI-Reorg passes allocation information to BMC AMI Reorg.
Automation control points	The following automation control points enable you to control copy processing: The XCPYDYNM-dynamic-image-copy-data-set-allocation-automation-control-point provides image copy data set names for each image copy. The XCPYINIT-copy-initialization-automation-control-point dynamically allocates tape drives. The XCPYMDIA-copy-media-selection-automation-control-point controls routing of image copies to disk or tape devices.

Example

//SYSIN DD *
NGTTAPE LP (UNITNAME(CART) DDNCOUNT(2) RETPD(8))
REORG TABLESPACE database.%

In the following example, only a Local Primary (LP) copy is requested. Since this is the default copy destination the Reorg statement does not have to specify it. The DDNCOUNT keyword mounts two tape drives for the LP copy to write copies in parallel.

In this example:

Only a local primary (LP) copy is requested.
The REORG statement does not need to specify the copy destination because it is the default.
The DDNCOUNT keyword mounts two tape drives for the LP copy to write copies in parallel.

Example

//SYSIN DD *
NGTTAPE LP (UNITNAME(VTS) DDNCOUNT(2) RETPD(8))
NGTTAPE RP (UNITNAME(VTSR) DDNCOUNT(2) RETPD(8))
REORG TABLESPACE database.%
RECOVERYDDN(RP)

a Remote Primary (RP) copy is requested so a RECOVERYDDN keyword is added to the Reorg statement. A COPYDDN keyword was still not required because the LP copy is required and will be produced. Having the NGTTAPE LP statement directs it to tape rather than the default of DASD

Example

//SYSIN DD *
NGTTAPE LP (UNITNAME(VTS) DDNCOUNT(2) RETPD(8))
NGTTAPE LB (UNITNAME(VTS) DDNCOUNT(2) RETPD(8))
NGTTAPE RP (UNITNAME(VTSR) DDNCOUNT(2) RETPD(8))
NGTTAPE RB (UNITNAME(VTSR) DDNCOUNT(2) RETPD(8))
REORG TABLESPACE database.%
COPYDDN(LP,LB) RECOVERYDDN(RP,RB)

NGTTAPE is used for all Db2 copy destinations. The REORG statement requests the copy destinations and the NGTTAPE statement specifies its destination which defaults to DASD if not specified
