Copying an index or table space concurrently

Use the Concurrent Copy on Index or Concurrent Copy on Table Space window to make the full image copy. The image copy is recorded in SYSCOPY with ICTYPE=F and STYPE=C. The RECOVER utility uses copies when recovering an index.

Authorities. Authorities and privileges


To copy an index or table space:

  1. Open the Concurrent Copy Index or Table Space window.
  2. Specify a share level by selecting a radio button:
    Reference
    Allows read-only access by other programs. When REFERENCE is specified, an ICTYPE=Q record is placed into the SYSCOPY table after the object has been quiesced. If COPY fails, then this record remains in SYSCOPY. When COPY is successful, then this ICTYPE=Q record is replaced with the ICTYPE=F record.

    For table spaces with a 32 KB page size, you must run the job with the REFERENCE option when using the CONCURRENT option. Otherwise, the job is terminated, and message DSNU423I is issued.

    Change
    Allows other programs to change the index. When you specify Change uncommitted data might be copied
  3. Optional: Select the Use one set of data sets for copy operation on all objects check box. If you select this setting, you must specify data set information.
  4. Specify Add to add an object and its data set information in the Add Object window.
  5. Specify Change to change an object and its data set information in the Change Object window.
  6. Specify parallel processing options.
  7. Click OK.

Specifying data set information

You must specify the Filter data set and Primary copy data set at local site information to enable OK.
Filter data set
Specifies the filter data set to be used automatically build a list of table spaces to be copied by DFSMS/DSS with one DFSMS/DSS "DUMP" statement. If this setting  is specified, the SYSIBM.SYSCOPY records for all objects in the list will have the same data set name.
Important: If you use the CONCURRENT and FILTERDDN options, make sure the size of
the copy data set is large enough to include all of the objects in the list.
Primary copy data set at local site
Specify a local copy data sets for the image copy
Backup copy data set at local site and Primary copy data set at recovery site are optional.
Restriction: Do not specify duplicate image copy data sets. If the data set specification identifies a noncataloged data set with the same name, volume serial, and file sequence number as one already recorded inSYSIBM.SYSCOPY, a message is issued and no copy is made. If it identifies a cataloged data set with only the same name, no copy is made.
