Zenwipe.sh: Erase Everything but Core

Zenwipe will remove everything except the Core product. This includes a full purge of:

• ZODB relstorage
• ZODB session
• ZEP
• Mysql
• Zenpacks

You can get it at https://dev.zenoss.com/tracint/browser/branches/core/zenoss-4.x/inst/zenwipe.sh

You can also selectively purge single items by editing the script. For example, you can remove the ZEP database only with this derivative script:

Removing Broken Zenpacks

Daniel Robbins has written a script that detects damaged zenpacks and attempts to remove them: http://wiki.zenoss.org/Removing_Broken_ZenPacks

To use it you must use it via zendmd:

zendmd --script=zenpack-remove.py

Or you can try to manually remove it interactively in zendmd:

dmd.ZenPackManager.packs._delObject('ZenPacks.zenoss.ZenPackName')
