Patch Name: PHSS_17852 Patch Description: s700_800 10.X OpenMail B.05.10 ual.remote performance fix Creation Date: 99/03/04 Post Date: 99/03/09 Hardware Platforms - OS Releases: s700: 10.01 10.10 10.20 10.30 s800: 10.01 10.10 10.20 10.30 Products: OpenMail B.05.10 Filesets: OpenMail.OM-CORE,A.B8.03 OpenMail.OM-RC,A.B7.00 Automatic Reboot?: No Status: Special Superseded Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHSS_17852 Symptoms: PHSS_17852: D500424499: Since 5.20, ual.remote sessions consume a lot more CPU time when they are in an idle state, compared to pre-5.20 systems. Defect Description: PHSS_17852: D500424499: When a ual.remote process is idle, it is blocked waiting for data from the client socket. Pre-5.20, it used the recv() unix system call to do this, wheras with 5.20 this was changed to use the select() system call because it could also receive notifications from the Notification Monitor. Tests have shown that the select() system call is very inefficient compared to the recv() call.

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 PHSS_17852 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHSS_17852.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/PHSS_17852.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/PHSS_17852. 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 PHSS_17852.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/PHSS_17852.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: SUBSYSTEM_SHUT =========================================================== PHSS_17852: =========================================================== D500424499: ----------- To force ICE client ual.remote sessions to use the more efficient recv() system call, the Notification Monitor Server-Push mechanism must be disabled using the UAKD_SERVER_PUSH_NOTIFS=FALSE general.cfg setting. This will cause the network traffic between Outlook clients and the Notification Server to increase significantly and so is not recommended on systems with high numbers of Outlook users. ---------------------------------------------------------- This patch will need the following minimum disk space requirements: /opt/openmail/patch : 3 MB /opt/openmail/B.05.10.00 : 3 MB /var/adm/sw : 3 MB (unless PATCH_NOSAVE is specified) ----------------------------------------------------------
