The default setting, 0 , instructs the driver to return an error message when unsupported characters are used. A value of 2 specifies that no default user ID should be provided if the connection string does not provide one. Setting this value to 1 allows the driver to translate this binary data to text data. If equidistant, round up. Use value 1 to turn on support for true ODBC auto-commit. For more information on setting this option see the fine-tuning record blocking topic. You would then use the integer to look up the employee picture large object from the large objects table.

This can really improve the processing of a reporting or web application that is listing data.
I have never understood this; I think sometimes it is change for the sake of change. Iseriex, execute the following VB code; you will not be able to call the procedure unless you do this. You can have a.
I have written many Midrange Guru Tips about packages, dynamic versus static SQL and the use of dtring markers so reference those articles or the resources section on my web site if you need to know how packages can help connection application. There is a good internet resource regarding connectionstrings of all flavors: The DBQ keyword, can also be specified as DefaultLibrariesallows you to specify the library list that the connection should have.
IBM Client Access ODBC Driver versus iSeries Access ODBC Driver – United States
ODBC has several API functions for querying the connected systems catalogues to find information on tables, indexes, columns, primary and foreign keys and permissions. This increases performance when accessing the initial rows.
This name change may impact some applications. Option 8 causes the iSeries to print your job log once the job ends. The only time to turn this off, IMHO, is when accessing large binary objects that are already compressed or do not lend themselves to compression as you are not gaining the benefit of compression an are incurring needless overhead.
Sometimes, if the package file is small, this can improve the performance of the ODBC application. When set, the driver will try to optimize the fetching of records when one record is requested by the application.
Connection string keywords
This option supports cases in which date values such as Specifies the maximum precision of decimal data that will be returned. I had a case where a statement had no markers but was taking a while to optimize because it was joining several legacy files together that had many logical files over each physical.
An empty-string indicates to use the user-profile’s default ofbc for database. Note that the string generator will not usually put options into the connection string if you choose the default value for the option.

You would then use the integer to look up the employee picture large object from the large objects table. Larger LOB thresholds will reduce the frequency of communication to the server, but will download more LOB data, even if it is not used.
Use only as directed by your technical support provider. Specifies the maximum LOB large object size in kilobytes that can be retrieved as part of a result set. This might not be advisable, as if you have a lot of files in a lot of libraries this can take quite a bit of time. Specifies whether to compress data sent to and from the server.
I have no idea what is going on with that argument, and setting it to or 0 seems to have no discernable effect. Option 16 tells the driver to add positioned updates and deletes to the package files. If an older version of Client Access is then installed, any datasources migrated to iSeries Access for Windows will fail to connect see Note.
In most cases, data compression improves performance due to less data being transmitted between the driver and the accesw. All of the above can be avoided by using a connection string rather than using an ODBC data source name when connecting. I use this value when coding user query applications to ensure that the user can only issue SQL Select or stored procedure calls. Specifies one or more debug options.
