Customizing and binding profiles for Structured Query Language in Java SQLJ applications Simplify the process of customizing and binding SQLJ profiles for your applications by performing these functions in the administrative console or with scripting. Do not re-customize the serialized profiles. If -longpkgname is not specified, package-name must be an alphanumeric string of eight or fewer bytes. All options are passed to the Java compiler and are not used by the SQLJ translator, except for the following options: You can do that in one of the following ways:

If the connection is to a Db2 on Linux, UNIX, and Windows systems server, database is the database name that is defined during installation.
Example of a simple SQLJ application
The default behavior is to do online checking. Use one of the following methods to bind the packages: Using the -collection parameter: Bytes-from-program-name IDNumber PkgIsolation Table 1 shows the parts of a generated package name and the number of bytes for each part.
Support for distributed transaction management. Letting db2sqljcustomize generate package names is not recommended.
Deploying SQLJ applications
Using a customized serialized profile at one data source that was customized at another data source: When you use db2sqljcustomize to create a single Db2 package from multiple serialized profiles, sqkj must also specify the -rootpkgname or -singlepkgname option. The SQLJ program preparation process.
The db2sqljcustomize option -longpkgname is specified. This driver is also known as: Customizing and binding SQLJ profiles with the db2sqljcustomize tool.
Customizing multiple serialized profiles together: Optionally does online checking to ensure that application variable types are compatible with the corresponding column data types. If -longpkgname is not specified, package-name must be an alphanumeric string of eight or fewer bytes.
You might also need to run the db2sqljbind command under these circumstances: For example, you might want to move your application from a test environment to a production environment.
The SQLJ command runs without connecting to the database server.
DB2 11 – Java -Binding SQLJ applications to access multiple database servers
When you run the programs at these data sources, the Db2 objects that the programs access must be identical at every data source. You can determine the location name by executing the following SQL statement on the server: Cached statements are often reused on the same Connection.
The SQL path is: Customizing and binding SQLJ sqlh with the administrative console or scripting. When you run the old version of the program, Db2 loads the old versions of the packages.
If the connection is to an IBM Cloudscape server, the database is the fully-qualified name of the file that contains the database.
Customization stores a new package timestamp in the serialized profile, which makes the new serialized profile incompatible with the original package. The translator puts the serialized profiles for file1. The number of packages and the isolation levels of those packages are controlled by the -rootpkgname and -singlepkgname options.
Installing the IBM Data Server Driver for JDBC and SQLJ
The XA Specificationavailable from http: Online checking is always recommended: When db2sqljcustomize runs, it creates a customized serialized profile. 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. After you bind the packages, you need to ensure that when the application runs, the Db2 database server at ZOS2 can find the packages.
Deploying CMP beans during the application installation in the application server. Command parameters -help Specifies that the SQLJ translator describes each of the options that the translator supports.
