Manually reset DB2 configuration variables

Note:   This procedure is optional, as configuration variables are typically reset by the uninstalldb2.sh script.

Perform the procedure described in this section to manually set the DB2 configuration variables back to the values they had before the plug-ins were installed. If you know the original plug-in values, reset them accordingly.

If you do not know the original values, use the following commands to reset the variables to their default values. Run these commands as the instance owner:

db2 update dbm cfg using SRVCON_AUTH NOT_SPECIFIED
db2 update dbm cfg using AUTHENTICATION SERVER
db2 update dbm cfg using GROUP_PLUGIN NULL
db2 update dbm cfg using LOCAL_GSSPLUGIN NULL
db2 update dbm cfg using SRVCON_GSSPLUGIN_LIST NULL
db2 update dbm cfg using SRVCON_PW_PLUGIN NULL

Note:   These commands work for both a DB2 client and a DB2 server.
