NDB_PERROR(1)

NAME
ndb_perror - obtain NDB error message information

SYNOPSIS

ndb_perror options

DESCRIPTION

ndb_perror shows information about an NDB error, given its error code. This includes the error message, the type of error, and whether the error is permanent or temporary. This is intended as a drop-in replacement for perror --ndb, which is no longer supported. Usage

    ndb_perror [options] error_code

ndb_perror does not need to access a running NDB Cluster, or any nodes (including SQL nodes). To view information about a given NDB error, invoke the program, using the error code as an argument, like this:

    $> ndb_perror 323
    NDB error code 323: Invalid nodegroup id, nodegroup already existing: Permanent error: Application error

To display only the error message, invoke ndb_perror with the --silent option (short form -s), as shown here:

    $> ndb_perror -s 323
    Invalid nodegroup id, nodegroup already existing: Permanent error: Application error

Like perror, ndb_perror accepts multiple error codes:

    $> ndb_perror 321 1001
    NDB error code 321: Invalid nodegroup id: Permanent error: Application error
    NDB error code 1001: Illegal connect string

Additional program options for ndb_perror are described later in this section.

ndb_perror replaces perror --ndb, which is no longer supported by NDB Cluster. To make substitution easier in scripts and other applications that might depend on perror for obtaining NDB error information, ndb_perror supports its own “dummy” --ndb option, which does nothing.

The following table includes all options that are specific to the NDB Cluster program ndb_perror. Additional descriptions follow the table.

Additional Options

    • --defaults-extra-file
    Command-Line Format | --defaults-extra-file=path
    Type | String
    Default Value | [none]

    Read given file after global files are read.

    • --defaults-file
    Command-Line Format | --defaults-file=path
    Type | String
    Default Value | [none]

    Read default options from given file only.

    • --defaults-group-suffix
    Command-Line Format | --defaults-group-suffix=string
    Type | String
    Default Value | [none]

    Also read groups with concat(group, suffix).

    • --help, -?
    Command-Line Format | --help

    Display program help text and exit.

    • --login-path
    Command-Line Format | --login-path=path

    Skips reading options from the login path file.

    • --ndb
    Command-Line Format | --ndb

    For compatibility with applications depending on old versions of perror that use that program's --ndb option. The option when used with ndb_perror does nothing, and is ignored by it.

    Command-Line Format | --no-defaults

    Do not read default options from any option file other than login file.

    • --print-defaults
    Command-Line Format | --print-defaults

    Print program argument list and exit.

    • --silent, -s
    Command-Line Format | --silent

    Show error message only.
