Info

► To install all filesets associated with fix IX38794 from the CD-ROM, enter: instfix -k IX38794 -d /dev/cd0 Note: If you choose to apply the updates during installation (rather than committing them at installation time), you can still reject those updates later. If a particular update is causing problems on your system, you can reject that update without having to reject all the other updates that you installed. Once you are convinced that the updates cause no problems, you may want to commit those updates to retrieve the disk space that is used to save the previous levels of that software. After you have installed a new fix, use the lppchk command to check if the installation was successful. The lppchk command verifies that files for an installable software product (fileset) match the Software Vital Product Data database information for file sizes, checksum values, or symbolic links. The useful flags are shown in Table 11-1. Table 11-1 Commonly used flags of the lppchk command Flag Description -c Performs a checksum operation on the input file list items and verifies that the checksum and the file size are consistent with the SWVPD database -f Checks that the file list items are present and that the file size matches the SWVPD database -l Verifies symbolic links for files, as specified in the SWVPD database If you have been installing software using SMIT, the screen returns to the top of the list of messages that are displayed during installation. You can review the message list as described in the next step, or you can exit SMIT and review the $HOME/smit.log file. After you check that the installation is successful, you should create a new boot image using the bosboot command: bosboot -ad /dev/hdiskX 314 IBM ^ Certification Study Guide - AIX 5L Problem Determination Tools and Techniques
11.3 Software inventory After all the software installations, you can check what is really installed with the instfix and lslpp commands. 1. To display the most recent level, state, description and all updates of the bos.sysmgt.trace fileset, run the following command: # lslpp -La bos.sysmgt.trace Fileset Level State Description ------------------------------------------------------------------------bos.sysmgt.trace 4.3.3.0 C Software Trace Service Aids 4.3.3.11 C Software Trace Service Aids ... 2. To see whether fix IX78215 is installed or information about each fileset associated with it, run the following command: # instfix -ik IX78215 -v IX78215 Abstract: trace allocates too much memory Fileset bos.sysmgt.trace:4.3.1.1 is applied on the system. All filesets for IX78215 were found. 3. To list maintenance level updates, enter: # instfix -i -tp All filesets for 4.3.1.0_AIX_ML were found. All filesets for 4.3.2.0_AIX_ML were found. All filesets for 4.3.1.0_AIX_ML were found. All filesets for 4.3.2.0_AIX_ML were found. All filesets for 4.3.3.0_AIX_ML were found. Or run instfix -i | grep ML. 11.4 Command summary This section shows a summary of some of the commands and their flags that are used for CPU performance problem determination. 11.4.1 The lslpp command The lslpp command displays information about installed filesets or fileset updates. The command has the following syntax: lslpp { -f | -h | -i | -L } ] [ -a ] [ FilesetName ... | FixID ... | all ] The most commonly used flags are provided in Table 11-2 on page 316. Chapter 11.
