Changing the gpmon Password

Greenplum Command Center manages the gpperfmon database using the gpmon database role. To change the gpmon password, follow these steps: 1. Log in to Greenplum Database as a superuser and change the gpmon password with the ALTER ROLE command: # ALTER ROLE gpmon WITH PASSWORD 'new_password'; 2. Update the password in the .pgpass file, which is used by Greenplum Command Center. The default location for this file is the gpadmin home directory (~/.pgpass). The .pgpass file contains a line with the gpmon password.

GP - Kerberos errors and resolutions

Issue:1. Ticket granting has expired with the error message, ERROR: psql: GSSAPI continuation error: Unspecified GSS failure. The Minor code may also display the error message, GSSAPI continuation error: Ticket expired. Solution: Create a new ticket on the Master server using the following command: kinit -k -t /home/gpadmin/gpdb-kerberos.keytab db_user Note: -t is the keytab file and db_user is the user. Issue:2. The library required to run the kinit command does not exist in the LD_LIBRARY_PATH  set in the Greenplum binaries, producing the following error message: ERROR: kinit: relocation error: kinit: symbol krb5_get_init_creds_opt_set_fast_ccache_name, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference Solution: Unset the LD_LIBRARY_PATH. IMPORTANT NOTE: The above fix will cause the following error when you try to run Postgres commands:  ERROR: psql: error while loading shared libraries: libpq.so.5: cannot open shared object ...
