Defect Description: PHSS_26918: 8606244766 : This happens because of limitation on the size of event. 8606241744 : There is a data overflow issue resulting in the defect in rectrap. 8606251574 : The limitation on the size of event is the cause of this defect. 8606251055 : The free space computation was not performed correctly. 8606251033 : pmd behaviour is affected due to a wrong buffer size used. 8606251059 : The logic does not handle properly the case of an SNMPV2 inform PDU. 8606251057 : The computation of required free space was not performed correctly. Resolution: 8606244766 : Introduced new check points to handle the problem. 8606241744 : Proper checking introduced to prevent the data overflow problem. 8606251574 : Introduced new check points for event size to resolve this problem. 8606251055 : The buffer space computation algorithm has been corrected. 8606251033 : The format buffer size used in the OV_EVENT stack has been changed. 8606251059 : Code modified for ovtrapd to handle the case of SNMPV2 inform PDU. 8606251057 : The buffer space computation algorithm has been corrected.

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_26918 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHSS_26918.depot By default swinstall will archive the original software in /var/adm/sw/patch/PHSS_26918. 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_26918.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_26918.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: WARNING: This patch should not be loaded unless the last consolidated patch PHSS_24797 has been loaded. To check if this patch is on your system use the following command: swlist -l product -l fileset PHSS_24797 If swlist cannot find the patch, then you will need to obtain the PHSS_24797 patch and load it before loading this patch. ======================================================== BEFORE LOADING THIS PATCH... If there are any ovw sessions running on either the Management Station or on any Management Consoles, these sessions need to be closed. The "ovstop" command should then be executed. WARNING : the patch will not install if any Network Node Manager processes are detected. BACKUP ALL OpenView DIRECTORIES TO TAPE. This pre-caution ensures that if you have problems after installing the patch, you will be able to restore your current state from tape. NOTE : ovstart is NOT executed after the patch is loaded You will need to manually run ovstart. Also, in order to keep a history of the patches installed on your system the post-install script will attempt to copy this .text file to /usr/OV/ReleaseNotes/patches (or /opt/OV/ReleaseNotes/patches). Please make sure this file is in /tmp before installation. ======================================================== PHSS_26918: The following patch(es) need to be installed along with the current patch to get the issue resolved.
