Patch Name: PHCO_15679 Patch Description: s700_800 10.20 cron(1M) and at(1) cumulative patch Creation Date: 98/06/24 Post Date: 98/06/26 Warning: 98/07/10 - This Critical Warning has been issued by HP. - Patch PHCO_15679 introduces problems with at(1), batch(1), and cron(1M). - The version of cron(1M) in the patch does not execute at(1) and batch(1) jobs properly. The jobs will be initialized correctly and the cron log shows that the jobs have terminated successfully, but the jobs are not executed. - The version of cron(1M) in the patch also fails to mail standard output and standard error to the user for any jobs submitted via at(1), batch(1), or crontab(1). Jobs that redirect standard output or standard error to a log file may receive extraneous output in the output log. - HP recommends that this patch be removed from any system that utilizes at(1) or batch(1) jobs, and from any system that requires cron(1M) to mail output to users. The patch should also be removed from any SD-UX depots. - Patch PHCO_15234 will be re-released until a replacement patch is available.

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_15679 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHCO_15679.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_15679.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_15679. 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_15679.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_15679.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: Superseded patch PHCO_15234 unnecessarily contained file /usr/bin/crontab. This patch doesn't contain that file as it doesn't need any modification.
