The translator puts the Java source file for file1. The db2sqljcustomize command performs these tasks: This value represents the transaction isolation level for the package. When you run the programs at these data sources, the Db2 objects that the programs access must be identical at every data source. The type 2 and type 4 connections can be made concurrently. The general steps for enabling access of an existing SQLJ application to additional database servers are:.

Drivers of this type are generally dependent on a native library, which limits their portability.
Do this by using the same values for -rootpkgname and -collection when you bind the new packages that you used when you created the original packages. See the DB2 documentation for a complete list of customization options.
If the data server finds a match, it obtains the information about the parameters for that stored procedure from the Db2 catalog. The four generated package names are of the following form: If the connection is to a Db2 on Linux, UNIX, and Windows systems server, database is the sqlm name that is defined during installation.
Letting db2sqljcustomize generate package names is not recommended. This driver aqlj also known as: You can compile the Java program separately, but the default behavior of the sqlj command is to compile the program. Specification of -zosDescProcParms can lead to more efficient storage usage at run time. You cannot use connection sharing in WebSphere Application Server if you use context caching.
The privilege set of the process must include one of the following authorities: Optionally does online checking to ensure that application variable types are compatible with the corresponding column data types. Run the db2sqljbind command against each of the database servers.
Supported drivers for JDBC and SQLJ
The general steps for enabling access of an existing SQLJ application to additional database servers are:. For example, suppose that sqoj want the translator to process two files: Multiple serialized profile names must be separated by spaces.
Valid -url, -username, and -password values must be specified. However, context caching can result in significant resource consumption in the application server, and might have unintended side effects if it is not used correctly.
Output For each source file, program-name. The application server provides functionality to use SQLJ as the persistence mechanism for enterprise beans that use container-managed persistence. Type 3 Drivers that use a pure Java client and communicate with a data server using a data-server-independent protocol.
A serialized profile name is of the following form:.
DB2 11 – Java -Binding SQLJ applications to access multiple database servers
Specify only those program preparation options that are appropriate for the data source at which you are binding a package. If -longpkgname is not specified, package-name must be an alphanumeric string of eight aqlj fewer bytes. A01 A02 A03 A The SQLJ command generates a Java source program, optionally compiles the Java source program, and produces zero or more serialized profiles.
If a bind fails when db2sqljcustomize runs if you want to create identical packages at multiple locations for the same serialized profile.
The translator puts the Java source file for file1. Because of the native code, their portability is limited. If -longpkgname is specified, package-name must be an alphanumeric string of or fewer bytes. A serialized profile file for each connection context class that is used in an SQLJ executable clause A serialized profile name is of the following form: Before the bind operation can work, the following conditions need to be met: Commands for SQLJ program preparation. If you specify more than one serialized profile name, and if you specify or use the default value of -automaticbind YES, db2sqljcustomize binds a single Db2 package from the profiles.
