ClientAccountingString

The client accounting string. The default value is an empty string ("").

ClientApplicationName

The client application name. The default value is an empty string ("").

ClientEncAlg

Determines whether the AES encryption is used. Set this parameter to "AES" in order to use it. In such case the Authentication parameter will be considered equal to "SERVER_ENCRYPT".

ClientUserID

Connection Lifetime

Number of seconds for connection to live.

ConvertToLong

Determines whether varchar inputs should be reported as long varchar.

CurrentPackageSet

The schema name for selecting the package to use for subsequent SQL statements. If this parameter is set, the SET CURRENT PACKAGESET statement is executed each time when connecting. This statement specifies the schema name for selecting the package to use for subsequent SQL statements.

Database

The name of the database. If this parameter is not specified, it is assumed that name of the database is same as user name.

DB2Explain

Determines whether the server will generate Explain snapshot and/or Explain table information.

DBName

The database name. This parameter is only used when connecting to DB2 for z/OS and OS/390, and only if (base) table catalog information is requested by the application.

Default Command Timeout

The default time in seconds to wait while trying to execute a command before terminating the attempt and generating an error. 0 indicates no limit.

DelimIdent

Specifies whether any string within double quotes (") is treated as an identifier, and any string within single quotes (') is treated as a string literal.

DisableCursorHold

Determines the effect of a transaction completion on open cursors. Default value is false - the cursors are not destroyed after completing the transaction.

Enlist

Determines whether the connection is automatically enlisted in the current distributed transaction. The default value is true.

EnsureDefaultDFRM

Specifies whether to explicitly set the rounding mode to ROUND_HALF_EVEN.

ExecutionMode

Determines whether previously captured statements should be executed statically for client optimization using pureQuery. Can be either "static" or "dynamic". "static" means that statements that are captured and packaged in the database are executed statically, statements that have not been captured will be executed dynamically. "dynamic" means that all statements will be processed dynamically.

FitHighPrecisionType

The type of precision to use.

Values:

Graphic

Specifies if GRAPHIC (double-byte character) is returned as a supported SQL data type and what unit is used to report GRAPHIC column length. Can be an integer value from 0 to 3. Default value is 0. This means that GRAPHIC is not returned as a supported SQL data type, and the reported length of GRAPHIC columns equals the maximum number of DBCS characters in the column. 1 means that GRAPHIC is returned as a supported SQL data type, and the reported length of GRAPHIC columns equals the maximum number of DBCS characters in the column. 2 means that GRAPHIC is not returned as a supported SQL data type, and the reported length of GRAPHIC columns equals the maximum number of bytes in the column. 3 means GRAPHIC is returned as a supported SQL data type, and the reported length of GRAPHIC columns equals the maximum number of bytes in the column.

HostVarParameters

Determines whether the support for host variables is enabled.

Instance

The instance name for a local IPC connection.

Interrupt

An integer value (0, 1, or 2) representing the interrupt processing mode. 0 disables interrupt processing. 1 means that interrupts supported are sent, otherwise the connection is closed. 3 means that interrupts drop the connection. Default value is 1.

Isolation Level

The isolation level for the connection. The default value is "SQL_TXN_READ_COMMITTED". The supported values are: SQL_TXN_READ_UNCOMMITTED - Read Uncommitted (Uncommitted read), SQL_TXN_READ_UNCOMMITTED - Read Uncommitted (Uncommitted read), SQL_TXN_REPEATABLE_READ - Repeatable Read (Read Stability), and SQL_TXN_SERIALIZABLE - Serializable (Repeatable read).

Max Pool Size

The maximum number of connections allowed in the pool. Setting the Max Pool Size value in the connection string can affect performance. The default value is 100.

Min Pool Size

The minimum number of connections allowed in the pool. The default value is 0.

Password

The password for the DB2 login account.

Persist Security Info

Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.

Pooling

If true, by default, the connection is drawn from the appropriate pool or is created and added to the appropriate pool.

ProgramId

User-defined character string, that associates an application with a connection. The string can be of up to 80 bytes.

ProgramName

The user-defined or default application name. By default, the first 20 bytes of the executable file name are used.

PureQueryXML

The file name and path of the capture file.

RetrieveXmlInBinaryFormat

Determines whether the XML data should be retrieved in a binary format.

RetryParameterBindingOnError

If parameters are defined with an incorrect datatype, this will result in an error. When this property is set to true, the describe information is used to attempt to determine the correct datatype for the parameter and the statement is re-executed. Setting RetryParameterBindingOnError to true will preserve this functionality. However, this may decrease performance, so it is recommended to set it to false and define parameters correctly.

RootPkgName

The package identifier for the package name (collection.rootPkgName) to be used by pureQuery when ExecutionMode is set to static.

SchemaList

The list of schemas to use. The schema names in the list are case-sensitive, must be delimited with single quotes, and separated by commas. The maximum length of the string is 256 characters.

Security

If you want to enable SSL, set this parameter to SSL.

Server

The host and port to connect to, separated with a colon. For example, "db2server:5000". Port may be omitted.

ServerType

The data server type to connect to. Can be "UNIDATA" or "UNIVERSE". The default value is an empty string ("").

SSLClientKeystash

The name of the SSL stash file used for an SSL connection. Must be specified together with the SSLClientKeystoredb connection string parameter in case the Security parameter is set to "SSL". The SSL stash file stores an encrypted password to the key database file.

SSLClientKeystoredb

The name of the SSL key database file used for an SSL connection. Must be specified together with the SSLClientKeystash connection string parameter in case the Security parameter is set to "SSL".

StatementConcentrator

Determines whether statement concentrator literals are enabled. Can be "Off" or "Literals". If this parameter is not specified, the behavior is determined by the server configuration.

StaticLatch

Determines whether to enable static blocking.

SysSchema

An alternative schema to be searched.

TargetPrincipal

The fully qualified Kerberos principal name of the DB2 instance owner for a target server. Used when the Authentication connection string parameter is set to "KERBEROS".

TraceFile

The name of a file to which all the connection trace information is written. If the file specified does not exist, then it will be created; otherwise, the new trace information will be appended to the end of the file. However, the path to the file must exist. If the filename given is invalid or if the file cannot be created or written to, no trace will occur and no error message will be returned. It is not recommended to use tracing in a multithreaded application, because all the threads will write to the same output file, and the output will be hard to decipher.

Transaction Scope Local

If there are several connections with the same connection string (which includes "Transaction Scope Local=true;") within a scope of TransactionScope, our provider will use only one connection internally. The default value is false. Not available in Mobile Edition.

TrustedContextSystemPassword

The password for the SYSTEM AUTHID of the trusted context.

TrustedContextSystemUserID

The trusted context SYSTEM AUTHID for the connection.

User

The DB2 login account.

Validate Connection

Specifies whether to validate connections that are being got from the pool.

WalletID

The encryption key wallet ID for U2 Data Server.

WalletPwd

The encryption key wallet password for U2 Data Server.
