What to do if you forget the database password?

Get the DBA to change the password to something that you know
cd bin directory
./kEncrypt.sh
It prompts you for the new password eg: rml
It generates an encrypted string eg:
#!#40$JMfc6VvL:&-6Car:eD6kC}AIsQX_NmxX3f&:YizzM.p^0.zc:hg4IO}Imr`cdzKT_z:2UY bfG>+Hp)_Gf36Rs9Fng,8P{O:D*_X{Rb..9In9q.~Aj~`3H=NqhSJmowejdC4Y_/NU^3~3v$Y8^RrZu$=K$$vKLU8QZWV~J)<{bnHP>A@N:bwDC?7_#!#
Copy it
Paste it into the server.conf file in the appropriate place eg:
## The password for the RML schema.#com.kintana.core.server.RML_PASSWORD=#!#40$JMfc6VvL:&-6Car:eD6kC}AIsQX_N?mxX3f&:YizzM.p^0.zc:hg4IO}Imr`cdzKT_z:2UY bfG>+Hp)_Gf36Rs9Fng,8P{O:D*_X{Rb..9In9q.~Aj~`3H=NqhSJmowejdC4Y_/NU^3~3v$Y8^RrZu$=K$$vKLU8QZWV~J)<{bnHP>A@N:bwDC?7_#!#
