4.6.2 Notes about upgrading
Note the following about upgrading an HADB client:
-
When performing a version upgrade of the HADB client, install an HADB client that corresponds to the version of the HADB server.
-
There are precautions regarding the installation data. Before upgrading the HADB client, for the Windows version of the HADB client, refer to the notes in (1) Installing an HADB client of 4.2.1 HADB client for Windows. For the Linux version of the HADB client, refer to the notes in (2) Installing an HADB client of 4.2.2 HADB client for Linux.
-
You must not change the OS user while the HADB client is being upgraded. If the OS user is changed, the HADB client might not be upgraded successfully.
-
You must not change the value of the ADBCLTLANG environment variable while the HADB client is being upgraded. If the value is changed, the HADB client might not be upgraded successfully.
-
Make sure that the versions of the HADB client and ODBC driver match. If the versions do not match, an error occurs before the HADB client connects to the HADB server.
-
From HADB 06-00, the name of the HADB ODBC driver will be changed to Hitachi Advanced Database ODBC Driver. Therefore, when using the HADB ODBC driver and performing a version upgrade of the HADB client from a version prior to 06-00, the following tasks will be necessary.
-
When using the Windows version of the HADB client
Before performing a version upgrade of the HADB client, re-registration of the registry key is necessary. To re-register the registry key, first delete the registry key by using the registry deletion command, and then register the registry key using the registry registration command. For details, see 4.2.1 HADB client for Windows.
Also, if you are using the ODBC driver name for the connection attribute (DRIVER) in the connection string of the SQLDriverConnectW function and SQLBrowseConnectW function, change the specified string from Hitachi Advanced Data Binder ODBC Driver to Hitachi Advanced Database ODBC Driver.
-
If you are using the Linux version of the HADB client
After upgrading the HADB client, change the driver name in the odbcinst.ini file and odbc.ini file from Hitachi Advanced Data Binder to Hitachi Advanced Database.
Also, if you are using the ODBC driver name for the connection attribute (DRIVER) in the connection string of the SQLDriverConnectW function and SQLBrowseConnectW function, change the specified string from Hitachi Advanced Data Binder ODBC Driver to Hitachi Advanced Database ODBC Driver.
