Information
Limited support BMC provides limited support for this version of the product. As a result, BMC no longer accepts comments in this space. If you encounter problems with the product version or the space, contact BMC Support.BMC recommends upgrading to the latest version of the product. To see documentation for that version, see BMC AMI Copy for Db2 13.1.

Functional differences

The following list provides functional differences between 

BMC AMI Copy

 and the IBM Db2 COPY utility:

  • The COPYDDN, FULLDDN, and BIGDDN options allow up to four DDNames for multiple copies.
  • BMC AMI Copy can make data set level index space image copies of nonpartitioning indexes or image copies of indexes with the COPY NO attribute and register the copies in the BMC-provided table, BMCXCOPY.
  • BMC AMI Copy can use multitasking to decrease elapsed time irrespective of the output medium. The IBM Db2 COPY utility only allows subtasking when creating disk image copies.
  • BMC AMI Copy provides a RUNSTATS option that gathers and reports statistics and updates the Db2 catalog and the BMCSTATS tables in the same pass of the data that is used to make image copies.
  • BMC AMI Copy allows wildcards to be used in database and space names. The IBM Db2 COPY utility supports wildcards only when using a the Db2 LISTDEF definition.
  • BMC AMI Copy allows multiple spaces to be listed in a single TABLESPACE or INDEXSPACE specification.
  • BMC AMI Copy allows consistent copies to be made while updates are in progress without additional hardware (by using BMC AMI Copy with the BMC SNAPSHOT UPGRADE FEATURE product).
  • BMC AMI Copy supports dynamic tape detection.
  • The RESETMOD option controls resetting the modified-page indicators in the table space.
  • BMC AMI Copy allows you to choose random or sequential I/O to the table space for incremental copies. The IBM Db2 COPY utility uses sequential I/O for incremental copies only for table spaces defined with the TRACKMOD NO attribute.
  • The COPY IMAGECOPY command allows you to make additional image copies off-line and does stacked tape analysis to optimally order the input copies.
  • BMC AMI Copy can optionally merge a new incremental copy with a prior incremental copy using the CUMULATIVE and RESETMOD options.
  • The KEEP option allows you to retain a merged incremental copy and then optionally reinstate it with the RECALL command.
  • BMC AMI Copy allows you to specify your own options module, as well as allowing you to override some of the installation options at execution time.
  • Multiple OPTIONS, OUTPUT, COPY, COPY IMAGECOPY, QUIESCE, RECALL, MODIFY, and TEMPLATE commands are allowed in the SYSIN input data set.
  • The FULL NO EMPTY NO option registers empty incremental copies in SYSIBM.SYSCOPY when BMC AMI Copy is able to acquire a registration point that would result in a reduction of log apply during recovery.
  • BMC AMI Copy does not support the Db2 commands -DISPLAY UTILITY and -TERM UTILITY.
  • BMC AMI Copy supports extended restart parameter options.
  • BMC AMI Copy supports SHRLEVEL REFERENCE when making concurrent copies by data set of a multi-data-set, nonpartitioned table space.
  • BMC AMI Copy allows you to establish a quiesce point for a space. QUIESCE BEFORE causes the space to be quiesced before the copy starts. QUIESCE AFTER causes it to be quiesced after the copy completes. This capability is especially useful when you specify SHRLEVEL CHANGE.
  • Multiple table spaces can be quiesced together to provide a common point of consistency.
  • Quiescing within BMC AMI Copy execution includes wait and retry logic for the IBM Db2 QUIESCE utility, resulting in less manual intervention than retrying a failed IBM Db2 QUIESCE job step.
  • The QUIESCE command allows you to perform a quiesce without making a copy.
  • The CHECKTSLEVEL option identifies damaged pages during the copy process, allowing you to take corrective action such as repairing a table space or recovering it from a prior copy. This prevents inadvertent duplication of damaged table spaces in image copies.
  • BMC AMI Copy does not support making DFSMS Concurrent-type copies.
  • BMC AMI Copy allows you to suppress specified messages or to send E- and W-type messages (errors and warnings) to a separate data set.
  • BMC AMI Copy provides options to allow you to specify what action BMC AMI Copy should take if it encounters certain errors.
  • BMC AMI Copy provides the ability to immediately migrate image copy data sets using HSM.
  • BMC AMI Copy optionally optimizes the stacking of incremental copies on tape to minimize tape handling and reduce elapsed time for recovery.
  • BMC AMI Copy includes the MODIFY command for SYSCOPY and BMCXCOPY maintenance and ICF catalog synchronization.
