Copying and Activating a Newer Version of a Published
PowerCube
After rebuilding or updating a published PowerCube, you can make the newer
version of the PowerCube available, without interruption, to IBM Cognos users.
Cognos Transformer copies the newer version of the cube to one or more
deployment locations that you specify, and then activates the newer version in
each location. Reports continue to run using the new cube data.
To copy and activate a PowerCube, Cognos Transformer does the following for
each deployment location:
v If this is the first time the cube has been copied and activated, Cognos
Transformer creates a small file named cube_name.mdc that represents the
PowerCube.
v Cognos Transformer creates a folder named cube_name__UTCdate_time and copies
the new version of the cube to this folder.
UTCdate_time represents the date and time that the copy process started, in
Coordinated Universal Time. For example, the following represents March 12,
2008 at 5:58:39 p.m. in UTC format: 20080312175839. This time format ensures
that folder names represent a standard global time, regardless of the time zone
in which cubes were copied and activated.
For time-based partitioned cubes, this folder contains additional files, including
a control cube, time-based control file (.vcd), and member cubes.
v If a cube_name__UTCdate_time.ver file exists, Cognos Transformer deletes this file.
Only one cube_name__UTCdate_time.ver file can exist in each deployment
location.
Cognos Transformer creates a file named cube_name__UTCdate_time.ver. The
prefix of this file name (cube_name__UTCdate_time) is the same as the folder in
this directory that contains the newest version of the cube.
v Cognos Transformer writes messages about this process to a log file, which is
stored in the location specified on the Directories tab of the Preferences property
sheet.
You can use a different value than UTCdate_time if you manually change this value
in the deployment location. Ensure that you change the value in both the prefix of
the .ver file and the folder that contains the newest version of the cube. The format
for both the prefix and the folder name must include two values that are separated
by a two underscores (__), as follows: value__value. For example, for the .ver file,
you can use the following: MyCube__1v2.ver. You cannot use MyCube_1v2.ver
(single underscore) or MyCube##1v2.ver (two hash symbols).
Note: You can also initiate the copy and activate process using the -gcommand
line option "-g option" on page 225. To activate an updated PowerCube that was
manually copied to the deployment location, use the pcactivatecommand
("Activating a Published PowerCube Using pcactivate" on page 189).
Procedure
1. If not done before, perform "Setting up a Copy and Activate Strategy" on page
188.
2. In the PowerCubes list in Cognos Transformer, right-click the PowerCube and
click Copy and Activate Selected PowerCube.
