SSHClientCertA certificate to be used for authenticating the SSHUser.
SSHClientCertPasswordThe password of the SSHClientCert key if it has one.
SSHClientCertSubjectThe subject of the SSH client certificate.
SSHClientCertTypeThe type of SSHClientCert private key.
SSHServerThe SSH server.
SSHPortThe SSH port.
SSHUserThe SSH user.
SSHPasswordThe SSH password.
SSHServerFingerprintThe SSH server fingerprint.
UseSSHWhether to tunnel the Informix connection over SSH. Use SSH.

Firewall


PropertyDescription
FirewallTypeThe protocol used by a proxy-based firewall.
FirewallServerThe name or IP address of a proxy-based firewall.
FirewallPortThe TCP port for a proxy-based firewall.
FirewallUserThe user name to use to authenticate with a proxy-based firewall.
FirewallPasswordA password used to authenticate to a proxy-based firewall.

Logging


PropertyDescription
LogfileA filepath which designates the name and location of the log file.
VerbosityThe verbosity level that determines the amount of detail included in the log file.
LogModulesCore modules to be included in the log file.
MaxLogFileSizeA string specifying the maximum size in bytes for a log file (for example, 10 MB).
MaxLogFileCountA string specifying the maximum file count of log files.

Schema


PropertyDescription
LocationA path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemasThis property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
TablesThis property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
ViewsRestricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Caching


PropertyDescription
AutoCacheAutomatically caches the results of SELECT queries into a cache database specified by either CacheLocation or both of CacheConnection and CacheProvider .
CacheProviderThe name of the provider to be used to cache data.
CacheDriverThe database driver used to cache data.
CacheConnectionThe connection string for the cache database. This property is always used in conjunction with CacheProvider . Setting both properties will override the value set for CacheLocation for caching data.
CacheLocationSpecifies the path to the cache when caching to a file.
CacheToleranceThe tolerance for stale data in the cache specified in seconds when using AutoCache .
OfflineUse offline mode to get the data from the cache instead of the live source.
CacheMetadataThis property determines whether or not to cache the table metadata to a file store.

Miscellaneous


PropertyDescription
BatchSizeThe maximum size of each batch operation to submit.
DBLocaleThis property specifies what Charset/Encoding will be used to parse table data.
DefaultDomainThis property is used for the Oracle Database Gateway for ODBC.
EnableForeignKeyDetectionWhether to detect the foreign keys in ODBC.
IncludeDualTableSet this property to mock the Oracle DUAL table for better compatibility with Oracle database.
LimitKeySizeThe maximum length of a primary key column.
MapBigintToVarcharThis property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default.
MapToIntThis property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default.
MapToLongVarcharThis property controls whether or not a column is returned as SQL_LONGVARCHAR.
MapToWVarcharThis property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default.
MaximumColumnSizeThe maximum column size.
MaxRowsLimits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
OtherThese hidden properties are used only in specific use cases.
QueryPassthroughThis option passes the query to the Informix server as is.
ReadonlyYou can use this property to enforce read-only access to Informix from the provider.
RTKThe runtime key used for licensing.
SessionVariablesA semicolon-separated list of SET ENVIRONMENT commands to set on the current connection.
SwitchModeThis property allows you to specify a switching mode to select a server from AlternateServers as the active server.
SwitchStrategyThis property allows you to specify a switching strategy to select a server from AlternateServers as the active server.
TimeoutA timeout for connections in seconds.
UpperCaseIdentifiersThis property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway.
