Patch Name: PHCO_10114 Patch Description: s700_800 10.10 top(1) and ps(1) cumulative patch Creation Date: 97/02/13 Post Date: 97/02/21 Warning: 98/01/12 - This Non-Critical Warning has been issued by HP. - PHCO_10114 can cause top(1) to display wrong user names in the USERNAME field. The uid's displayed with 'top -u' are correct, only the user names are incorrect. - It is recommended that PHCO_10114 be removed from any system that relies on the user name information in the output of the top(1) command. If the NIS initialization enhancement provided in PHCO_10114 is required, then the 'top -u' command should be used to avoid the incorrect reporting of user names. - PHCO_10114 has been included in the following Extension Software General Release Patch Bundles: May 1997: XSW700GR1001 B.10.10.33 XSW800GR1001 B.10.10.33 Jul 1997: XSW700GR1001 B.10.10.34 XSW800GR1001 B.10.10.34 Oct 1997: XSW700GR1001 B.10.10.35 XSW800GR1001 B.10.10.35 Dec 1997: XSW700GR1001 B.10.10.36 XSW800GR1001 B.10.10.36 - Patch PHCO_7035 will be re-released until a replacement patch is available. Hardware Platforms - OS Releases: s700: 10.10 s800: 10.10 Products: N/A Filesets: OS-Core.CMDS-AUX OS-Core.UX-CORE Automatic Reboot?: No Status: General Superseded With Warnings Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHCO_10114 Symptoms: PHCO_10114: top has a long initialization time on systems with NIS. PHCO_7035: ps -p "proclist" only allows space or comma separated list of pids. PHCO_6599: There is a problem with the output of the top command at hpux 10.0. When the system is lightly loaded, everything is okay, but when the system begins to get users on it, the output becomes very strange. if a system has more than 300 tasks, top displays negative cpu usage. Defect Description: PHCO_10114: The problem occurred due to a linear search of the passwd file using getpwent(3C). A section of top was recoded to use getpwuid(3C) which has better performance under NIS. PHCO_7035: ps -p "proclist" only allows space or comma separated list of pids, not tabs. PHCO_6599: top displays invalid information if the system has more than 300 tasks. The problem is easily reproducable on a heavily loaded system, by running top. top will display negative values for cpu usage.

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHCO_10114 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHCO_10114.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHCO_10114.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHCO_10114. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHCO_10114.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHCO_10114.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
