Configuration :
A Windows Data Protector (DP) Cell Manger (CM).
Problem :
On the CM after an version upgrade, a DP patch installation or a DP Hotfix installation the CRS service or DP sessions do not start.
The debug.log file or DP debug trace files show shared memory problems similar to :
invalid shared memory size (size != 9303448)
Possible Solution :
DP upgrade :
* make sure that no DP sessions are running and ensure no sessions will start.
* make sure all GUIs are closed.
* Stop the DP services.
* Start Task manager End Process any remaining DP processes.
* Restart the DP services.
* if there is still a problem with upgrade, reboot the CM server before restarting the upgrade process.
* preferably use the local administrator user account instead of a domain account for upgrade.
DP patch installation :
* make sure that no sessions are running and no sessions will start.
* make sure all GUIs are closed.
* Stop the DP services.
* Start Task manager End Process any remaining DP processes.
* if still problem with patch installation, reboot the CM server before restarting the patch installation.
* preferably use the local administrator user account instead of domain account for installation.
DP Hotfix installation :
* make sure that hotfix is built for exact DP version and patch level you have installed.
* some hotfixes require all GUIs are closed.
* some hotfixes require installation when the DP services are stopped, if this is required, Stop the DP services.
* Start Task manager End Process any remaining DP processes.
* if still problem with hotfix install, reboot the Server before retrying the hotfix installation.
