The table below shows the operands checkable by the pdconfchk command and which must be examined if you want to apply compatibility mode. The operands are listed in alphabetical order.

Legend:

Y: Operand can be checked.

N: Operand cannot be checked.

Syntax check:

Checks whether the operand's syntax is correct.

File check:

Checks for the presence of the system log file, synchronization point dump file, and status file. A file check is not performed if the -n option is specified for the pdconfchk command.

Access privilege check:

Checks whether the HiRDB administrator has file access privileges.

Checks whether the HiRDB administrator has access privileges for the hosts file.

An access privilege check is not performed if the -n option is specified for the pdconfchk command.

Duplicate specification check:

Checks whether the system log files, synchronization point dump files, or status files are duplicated.

Host name check:

Checks whether the host name is written in the hosts file.

Check among server machines (applicable only to a HiRDB parallel server configuration):

Checks for compatibility among server machines using the server machine of the system manager as the reference.
