Fast Path Online Restructure/EP command set

The Fast Path Online Restructure/EP command set includes several primary commands.

You can use these commands to restructure a DEDB. Each command can execute as PFPSYSIN input to the PFCMAIN program that Fast Path Online Restructure/EP provides.

PREPARE command

By using the Fast Path Online Restructure/EP Prepare function, you can prepare for an online DEDB area restructure by creating a Restructure Plan data set that contains information about the areas that will be restructured. The PREPARE command is executed in a batch job, runs under the control of IMS, and submits online IFP tasks.

For more information, see Preparing for a DEDB restructure.

SHADOW_INIT command

By using the Fast Path Online Restructure/EP Shadow Initialization function, you can initialize the shadow area data sets. The SHADOW_INIT command is executed in a batch job.

For more information, see Initializing shadow area data sets.

RESTRUCTURE command

By using the Fast Path Online Restructure/EP Restructure function, you can alter or make changes to a DEDB area while it is online to IMS. The RESTRUCTURE command is executed in a batch job, runs under the control of IMS, and submits online IFP tasks.

For more information, see Restructuring a DEDB online.

RESTART command

By using the Fast Path Online Restructure/EP Restart function, you can restart the restructure process if

  • Errors occur during restructure post-processing activities

  • You requested early termination of the restructure process

The RESTART command is executed in a batch job and runs under the control of IMS.

For more information, see Restarting post-processing.

BACKOUT command

By using the Fast Path Online Restructure/EP Backout function, you can restore your database to its original state by undoing restructure changes if an error occurs during the online restructure process. The BACKOUT command is executed in a batch job and runs under the control of IMS. You cannot execute the BACKOUT command after the Restructure function completes or the DELTA step (new control blocks are moved into active libraries) for the Restructure function or Restart function has started.

For more information, see Backing out restructure changes if an error occurs.

STATUS command

By using the Fast Path Online Restructure/EP Status function, you can generate the Restructure Activity Report on demand. The STATUS command is executed in a batch job and runs under the control of IMS.

For more information, see Generating the Restructure Activity Report.
