BMC AMI Copy backup options

Specifies the name of a data set that is used to define a GDG base when no data set is named on the output copy data set options panel

The data set must contain the control cards that are necessary to perform an IDCAMS DEFINE as well as the symbolic variable &BASE, which BMC AMI Copy replaces with the GDG base name.

Causes BMC AMI Copy to pause or continue after completing XBM registration of SHRLEVEL CONCURRENT copies

The job halts after all INIT processing for a group of table spaces completes. At that time, all of the affected table spaces are under control of XBM. For more information, see the BMC AMI Copy for Db2 documentation.

specifies the percentage of changed pages that must occur to allow escalation from random I/O to full table space scan.

Merges the requested incremental RESETMOD NO copy with the most recent prior incremental RESETMOD NO copy

Specifies a day of the week on which a full copy will be made. Valid values are as follows:

1—Monday

2—Tuesday

3—Wednesday

4—Thursday

5—Friday

6—Saturday

7—Sunday

Specifies making a hardware-based Instant Snapshot copy of Db2 data, as follows:

Yes—make an Instant Snapshot copy

Auto—made a hardware copy if possible, but fall back to a standard copy if the hardware copy fails (for example if XBM, SUF, or the required hardware is not in place)

No—make a standard copy

Avoids making a copy when no pages changed since the last incremental copy was made

Specifies whether to make full or incremental image copies

• Yes—full image copy
• No—incremental copy
• Auto—automatically escalates to a full copy when it encounters one of the following conditions:
  • An entry in SYSCOPY prohibits an incremental copy.
  • The target object or partition is in copy pending status.
  • The target is a special case catalog or directory table space.
  • A specified number of incremental copies is reached.
  • A specified percentage of changed pages is reached.
  • A specified day of the week occurs.

Use the Full percent and Incremental percent options together to determine whether no copy, an incremental copy, or a full copy is made

Enter the incremental and full percentage values in either decimal or integer format. Valid integer values range from 0 to 100. Valid decimal values are 00.0 to 99.9. A decimal value can only be specified to the tenth’s place (1/10 of a percent).

To create an incremental copy when changed pages are between two limits, provide the lower limit at Incremental percent and the upper limit at Full percent. No copy is made if changed pages are less than or equal to Incremental percent.

To create a full copy when changed pages are equal to or more than a specific limit, provide that limit at Full percent.

Specifies that all spaces in the BMC AMI Recovery Manager group share a common consistent point

Retains the entry for the most recent prior (merged) incremental copy in the SYSCOPY table

Escalates to a full image copy when the number of incremental copies that are registered in SYSCOPY since the last full copy reaches a number that you specify (1 through 100).

Specifies the maximum number of tape tasks and the maximum number of tasks that are used by BMC AMI Copy when making image copies.

Specifies the minimum number of pages that must exist in a space or partition before an incremental copy can be made.

Valid values are 1 through 999999. If the number of pages is less than this value, a full copy is made.

Specifies whether to update the NACTIVE statistic in SYSIBM.SYSTABLESPACE.

BMC AMI Recovery Manager uses the NACTIVE statistic in SYSIBM.SYSTABLESPACE (which shows the number of active pages in the table space) for sizing and group split optimization.

Specifies what action to take if BMC AMI Copy encounters a copy data set that is already registered in SYSCOPY or BMCXCOPY, as follows:

• ERROR—terminate processing if the data set is already registered
• DELETE—continue processing when a data set is already registered. When BMC AMI Copy registers the new copy, it deletes the row containing the duplicate data set in SYSCOPY or BMCXCOPY. Only rows with the same DSNAME, TSNAME (IXNAME), or DSNUM as the new copy are deleted.

Specifies how to proceed when BMC AMI Copy encounters a table space or partition that has an unacceptable status or has a BMC or Db2 utility running against it, as follows:

• END—terminate processing with a RC=12
• SKIP—issue a message, skip over the space, and continue processing

Specifies how to proceed if BMC AMI Copy encounters a table space or partition for which an image copy already exists, as follows:

• END—terminate processing with a RC=12
• SKIP—issue a message, skip over the space, and continue processing other spaces as specified.

This option is effective for the COPY IMAGECOPY command.

Specifies how to proceed if BMC AMI Copy encounters a table space or partition that is of a type that is not supported by BMC AMI Copy, as follows:

• END—terminate processing with a RC=12
• SKIP—issue a message, skip over the space, and continue processing other spaces as specified.

This option is effective for both the COPY and COPY IMAGECOPY commands.

Specifies the method that is used to make incremental copies

Random—use the conventional (random I/O) method of making incremental copies

Fullscan—use full table space scan techniques to identify changed pages

Auto—determine the I/O method based on the number of changed pages

Instructs XBM or SUF to resynchronize hardware mirroring activities after an Instant Snapshot copy. You can specify No to leave the mirrors unsynchronized during subsequent user processing. If you choose No, you must manually reestablish the mirroring synchronization using XBM or SUF.

Updates the Db2 catalog or the BMCSTATS table with statistics that are collected concurrently with the creation of full image copies

If you collect statistics, you can also choose to report statistics (Report statistics option) and specify how the Db2 catalog tables or the BMCSTATS table should be updated.

Specifies making copies by partition when backing up partitioned table spaces

Specifies the level of access to the target spaces that BMC AMI Copy permits during the copy process, as follows:

• Reference—allows only read-only access by other programs during the copy process.
• Change—maintains the initial level of access of the spaces.
• Any—uses Shrlevel Change unless BMC AMI Copy encounters any conditions that require more restrictive access.
• None—stops all access by other programs to the target spaces during the copy process.

• Concurrent—utilizes the SUF product to make consistent copies of the table spaces while updates to those table spaces are in progress. You can specify a value of required or preferred for this option.

  • Concurrent required—terminates the copy with a return code of 12 if a consistent point cannot be obtained or maintained.
  • Concurrent preferred—uses Shrlevel Change when a consistent copy cannot be obtained or maintained or if initialization of the SUF or XBM fails.

  Important

  Shrlevel Concurrent is not valid with compressed indexes.

• Change Consistent Yes—use for Online Consistent Copy. This option requires a solution password and must be set at the group level.

Specifies whether to consolidate the rows on each target table space page so that all free space is contiguous

This option is obsolete for BMC AMI Copy version 6.3 and later.

Writes a string of not more than 50 characters to the operating system system log

This option is valid only with Group Yes and when using SUF to make Shrlevel Concurrent copies,

Instructs BMC AMI Copy to use an alternative descriptor for COPYDDN when the FULL AUTO FULLPCT settings cause a full copy to be made

If you specify Yes and a full copy is made, the image copy output goes to an alternate set of DDs that are specified with the following keywords:

Instructs BMC AMI Copy to use an alternative descriptor for COPYDDN when the number of pages to copy is equal to or greater than the outsize threshold value

If you specify Yes and the threshold condition is met or exceeded, the image copy output goes to an alternate set of DDs that are specified with the following keywords:

• BIGDDN
• BIGDSN
• BIGRECDDN
• BIGRECDSN

Specifies the number of units to be allocated for the output image copy data sets. Valid values are 0 to 59. Zero (0) enables you to control the unit count with SMS if required. The default is no unit count at all.

If you are using DSNUTILB COPY, you can cause BMC AMI Recovery Manager to calculate the unit count by setting a value in Max primary allocation.

Uses the BMC AMI Copy COPY IMAGECOPY command after a copy job to make additional image copies from a local site primary copy that is already registered in SYSCOPY, as follows:

• LB —local site backup copy.
• RP—recovery site primary copy.
• RB—recovery site backup copy

COPY IMAGECOPY is incompatible with compressed indexes.

Specifies the XBM subsystem ID (1-8 characters) to be used when making Shrlevel Concurrent copies
