NNM registry corrupt after upgrading PA 5.0 from 4.7 on some Windows 64 bit env

HP Technical document information Title: Problem upgrading Performance Agent (PA) 5.0 from 4.7 on some Windows 64 bit environments Document ID: KM764076 Product: performance agent,network node manager,reporter Version: 8.13,8.12,8.11,8.10 Updated: 2009-Sep-04 On 64-bit architectures (x86_64 or Itanium) running the Windows 64-bit Operating System, when the performance agent (PA) is upgraded from version 4.7 to version 5.0, other HP OpenView products (NNM and/or Reporter) which run in 32-bit emulation mode will experience problems. Note that this issue is specific only to upgrades and not a fresh installation of PA 5.0. The cause is that the following registry key values are overwritten as part of the PA 5.0 upgrade. These registry keys are also used by the above mentioned products: - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hewlett-Packard\HP OpenView\InstallDir - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hewlett-Packard\HP OpenView\DataDir There are two possible workarounds that can keep a system where NNM and/or Reporter coexist with PA safe from encountering these problems: 1. Uninstall the existing version of the Performance Agent and then install PA 5.0. To protect the data previously collected, save files such as the status.* files, the log* files, the parm file, the alarmdef file, and the mwakey file to some other location and then move them back to the appropriate "datadir" location subsequent to the completion of the 5.0 installation. Note that this alternative should be followed if upgrading from PA 4.6 or any earlier version of the Performance Agent, since the only supported direct upgrade path is from PA 4.7 to PA 5.0. 2. Perform the upgrade using the following sequence of steps: 1. Before starting, PA 5.0 upgrade, backup the relevant registry keys using following steps: A. Open the Registry Editor (Start Menu->Run->regedit.exe) B. Browse to the location "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hewlett-Packard\HP OpenView" in the registry editor. C. Right Click, select "Export", and save to any location on the machine. 2. Perform the PA 5.0 upgrade using the procedure shown in the HP Performance Agent Windows Installation and Configuration Guide. 3. After PA is upgraded to 5.0, restore the required registry keys using following steps: A. Open Registry Editor(Start Menu->Run->regedit.exe) B. Go to File->Import, browse to the location where the registry keys were backed up in Step (1), and import them. Following either of the above procedures should allow the Performance Agent software to be upgraded to version 5.0 without impacting either NNM or Reporter. original link: http://support.openview.hp.com/selfsolve/document/KM764076?searchIdentifier=-68452887:12381b696e6:2b63&resultType=document&documentURL=KM764076&resultsURL=/selfsolve/documents&allowReturn=true
