When this property is “false”, writing truncated data to the database or using such data in a query generates no exception or warning. Specifies whether to delay closing cursors until subsequent requests. The IFSFile class provides methods that operate on a file as a whole. This property does not affect numeric data. If set to “1”, database metadata will be retrieved by calling system stored procedures. The SystemStatus class retrieves system status information. This can be useful to improve the performance of complex join conditions.

Note that libraries cannot be longer than 10 characters in length. The transaction object has the same api as the pool object. If you have complicated programs that run for longer than 3 sec then you need to adjust the timeout parameter for those specific calls.
Trace messages are useful for debugging programs that call JDBC. What exception do you get? The following criteria determine which database is accessed:. When working with a Java class for the first time, this is useful for experimenting with the behavior of the Java class without needing to write and compile a Java program. Using the prepared statements usually consists of three parts: Comments Sign in or register to add and subscribe to comments.
With programs it is neccesary to define your input parameters first. Larger block sizes reduce the frequency of communication datahase the system, and therefore may increase performance. Specifies the database to use for a connection to an independent auxiliary storage pool ASP.
Specifies the base name of the SQL package. Specifies whether an intermediate java.
As an enhanced developer tool, jdbcClient also allows the use of reflection to involve methods on Java and JDBC objects. Specifies the host name and port of the middle-tier machine where the proxy server is running. The SystemStatus class can be used to retrieve information such as the total number of user jobs and system jobs currently running on the system, and the storage capacity of the system’s databawe storage pool.
Post as a guest Name. The SystemValue class databse the retrieving and setting of a single system value. Specifies the password for connecting to adtabase system.
A qaqqini file contains all of the attributes that can potentially impact the performance of the DB2 for IBM i database engine. Specifies how the system treats case while sorting records. Specifies the buffer size used to receive data through the socket connection between the front-end driver and the IBM i system. Library list The system uses specified libraries to resolve unqualified stored procedure names, and stored procedures use them to resolve unqualified names.
IBM i provides several means to run executable programs on the system. Data compression may improve performance when retrieving large result sets.
A programmer can use the classes to interact with a message queue allowing messages to be sent, received, or replied to. When used in conjunction with a variable, the! In this case, you again need to add jt IBM i provides file resources in two forms. The SystemValueList represents a list of system values on the server. Specifies the block size in kilobytes to retrieve from the system and cache on the client.
These properties determine which JDBC driver is used, and specify options related to level of database access, bidirectional string type, data truncation and so on. When tracing is enabled, tracing starts when the client connects to the system and ends when the connection is disconnected.
This property has no effect if the “secondary URL” property is set.
