To set up checksum validation for additional files, database administrator needs to do the following: For example, if access rights to the file have been modified, the checksum will change. The fields are separated by three symbols: space, dash, space.Ĭhecksums control both contents and attributes of additional files. For example, for a cluster with /var/lib/pgpro/ent-13/data data directory, the configuration file is called _var_lib_pgpro_ent-13_.Įach line in the configuration file corresponds to a single controlled object and includes two fields: the checksum, consisting of 40 hexadecimal digits, and a relative path to the controlled object. The naming convention is as follows: the path to the data directory of the cluster ( PGDATA), with forward slashes replaced by underscores, followed by the. Each cluster must have a separate configuration file for additional files. Checksums for additional files are managed by configuration files stored in the share/security directory. Additional files are controlled files that can be modified by a database administrator.
