Referencing interim fixes

Edit online

The following are methods for referencing interim fixes.

Reference by Label

Each interim fix that is installed on a given system has its a unique interim fix label. This label is called the unique key that binds the different database objects. To reference an interim fix by label, pass the label as an argument to the -L flag.

For example, to run a check operation on an interim fix with label ABC123, type the following:
# emgr -cL ABC123
Reference by Interim Fix ID

Each interim fix that is installed on a given system has a unique interim fix ID. This ID is the order number in which the interim fix is listed in the interim fix database. Using this option may be convenient if performing operations on interim fixes based on interim fix listings. The emgr command converts the interim fix ID into an interim fix label before performing the given operation. To reference an interim fix by ID, pass the ID as an argument to the -n flag.

For example, to run a check operation on the first interim fix with an ID equal to 1, type the following:
# emgr -cn1
Note: Emergency fix IDs are valid for short periods of time and change as interim fixes are removed and added. Always verify the current interim fix ID number by listing the interim fix using the -l flag.
Reference by VUID
The VUID is used to differentiate packages that have the same label. Unlike Authorized Program Analysis Reports (APARs), which are officially tracked, emergency fixes are not tracked by any organization, so it is possible to have two interim fix packages with the same label. However, the emgr command does not allow the installation of more than one interim fix with the same label. The emgr command converts the VUID into an interim fix label before performing the given operation. For example, to list an installed interim fix with VUID equal to 000775364C00020316020703, type the following: 
# emgr -l -u 000775364C00020316020703

The VUID is also displayed in the preview section of the interim fix installation and removal operations, and when using the listing operation with verbosity level 2 or greater. For more information on verbosity levels, see Listing interim fixes
