In IBM speak an APAR simply is a formal report that describes a problem with an associated quick-fix. APAR stands for Authorized Program Analysis Report. Its’ main purpose is to describe and produce a workaround for a “bug” found on the target system. The “workarounds” are often identified by a unique ID released by IBM when a customer or IBM itself spots the problem within their AIX sytem.
The APAR that will be applied in this post relates to the following “bug” on AIX 6.1, oslevel -s, 6100-01-02-0834. A brief problem description is as follows: “Procstack does not work on AIX 6.1 for programs containing a JVM“. 🙂
To install the APAR:
- Acquire the packages either via FTP or physical media. Note that you can search anywhere on the IBM site (www.ibm.com) by entering the APAR ID into their search box.
- If the APAR was downloaded localy, run “inutoc .” in the same folder where the packages are. In this case the package files ending in (*.bff) reside under the folder: ../APARs/IZ71944
- Change directory to the target directory and run “smit update_all“
- In most cases a reboot is required after installing the APAR
# inutoc .
# smit update_all .
Follow the on screen prompts and commit the update when ready.
