It also creates Db2 packages, if the automaticbind value is YES. The db2sqljcustomize option -longpkgname is specified. If the collection ID for the additional Db2 packages that you create is different from the collection ID in the serialized profile, you need to override the collection ID that is in the serialized profile. To optimize a query properly that contains character host variables, Db2 needs the length of the host variables. Change the code in your source program.

The -qualifier parameter applies to online checking only. Program preparation for SQLJ programs involves translating, compiling, customizing, and binding programs. Deploying CMP d2b during the application installation in the application server.
When you bind the packages, you need to specify the following bind option values: Therefore, the four package names are: All characters in this value must be uppercase characters. Type 4 Drivers that are pure Java and implement the network protocol for a specific data source. The general steps for enabling sb2 of an existing SQLJ application to additional database servers are:.
DB2 11 – Java -Binding SQLJ applications to access multiple database servers
When -zosDescProcParms is specified, the Db2 data server uses the specified or default value of -zosProcedurePath to resolve unqualified names of stored procedures for which SQL data type information is requested.
To ensure uniqueness of package names, specify -rootpkgname.
If you do not specify -rootpkgname or -singlepkgname, db2sqljcustomize generates four package names that are based on the serialized profile name. Customizing and binding SQLJ applications again without needing to reinstall the application. The db2sqljcustomize option -longpkgname is not specified.
These enhancements reduce the complexity of installing, deploying, and customizing SQLJ applications for both container-managed and bean-managed persistence. The SQLJ command runs without connecting to the database server. The SQLJ translator searches for. By default, when an SQLJ application runs, the Db2 database server looks for packages using the collection ID that is stored in the serialized profile.
Specify the serialized profile names, one on each line, in a file with the name file-name. If -longpkgname is specified, package-name must be an alphanumeric string of or fewer bytes.
db2sqljcustomize – SQLJ profile customizer
D2b a customized serialized profile at one data source that was customized at another data source: The translator uses the directory structure of the SQLJ source files when it puts the generated files in directories. In addition to accessing data at the location that is indicated by URL jdbc: A serialized profile name is of the sqqlj form:.
You cannot run db2sqljcustomize on individual files, and then group those files when you run db2sqljbind.
The -username value must have authorization to bind a package at the target data source. 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. If the collection ID for the additional Db2 packages that you create is different from the collection ID in the serialized profile, you need to override the collection ID that is in the serialized profile.
Application management command group for the AdminTask object. You can do that in one of the following ways: Specification of -zosDescProcParms can lead to more efficient storage usage at run time.
Deploying SQLJ applications
If -longpkgname is specified, package-name-stem must be an alphanumeric string of or fewer bytes. If -longpkgname is not specified, package-name must be an alphanumeric string of eight or fewer bytes.
The Db2 database server inserts that list into the SQL path for resolution of unqualified stored procedure names. You can run db2sqljcustomize to produce a customized serialized profile for an SQLJ program at one data source, and then use that profile at another data source.
If any generated package names are the same as the names of existing packages, db2sqljcustomize overwrites the existing packages. The SQLJ program preparation process.
