Use the tool for registering HiRDB client environment variables to register environment variables in the registry.
To use the tool for registering HiRDB client environment variables, execute xxxx\UTL\pdcltadm.exe (xxxx is %PDDIR%\client in the HiRDB server and the HiRDB client installation directory in the HiRDB client).
The rest of this section describes procedures for registering environment variables in the registry with the tool for registering HiRDB client environment variables.
In an OLE DB connection, the environment variables registered with the tool for registering HiRDB client environment variables have priority over the user environment variables and the specifications in HIRDB.INI.
Client environment definitions set using this method become invalid when the Type4 JDBC driver is used. Client environment definitions that begin with PDJDB become invalid if this method is used.
Execute xxxx\UTL\pdcltadm.exe. The Tool for Registering HiRDB Client Variables dialog box is displayed.

Select either User Group or System Group, and click the Add button.
The HiRDB Client Environment Variable Setup dialog box is displayed.

After completing the setup, click the OK button. When the OK button is clicked, the client environment variable settings are registered in the registry, and the Tool for Registering HiRDB Client Variables dialog box is displayed again.
Click the Cancel button to cancel the client environment variable settings and return to the Tool for Registering HiRDB Client Variables dialog box.
After one or more environment variable groups are registered, a list of the registered environment variable group names is displayed, as shown in the next dialog box.

When an environment variable group name in the list is selected, the Delete, Configure, and Test buttons become enabled and can be clicked. Click the Configure button or double-click an environment variable group name in the list. The following dialog box is displayed:
![[Figure]](FIGURE/GMN0611.GIF)
Change the environment variable settings, and click the OK button. When the OK button is clicked, the new client environment variable settings are registered in the registry, and the Tool for Registering HiRDB Client Variables dialog box is displayed again.
Click the Cancel button to cancel the client environment variable settings and return to the Tool for Registering HiRDB Client Variables dialog box.
You can use a registered environment variable group to check whether a connection to HiRDB can be established for that group.
From the environment variable group name list in the Tool for Registering HiRDB Client Variables dialog box, select the environment variable group name for which connection to HiRDB is to be checked, and click the Connect button. The following dialog box is displayed:
![[Figure]](FIGURE/GMN0613.GIF)
Click Yes.
If connection to HiRDB is successful, the following dialog box is displayed:
![[Figure]](FIGURE/GMN0614.GIF)
If connection to HiRDB fails, the following dialog box is displayed. If the error is due to the contents of an environment variable, change the settings of the environment variable group.

From the environment variable group name list in the Tool for Registering HiRDB Client Variables dialog box, select the environment variable group name to be deleted, and click the Delete button.
The following dialog box is displayed:

The OLE DB provider trace is for troubleshooting only. Do not set this trace for any other investigation. Note that when a trace is performed, the performance of other operations may drop dramatically.
To set an OLE DB provider trace when the HiRDB client is connected to an OLE DB, open the Tool for Registering HiRDB Client Variables dialog box, and click the OLE DB Trace button. The following dialog box is displayed:
![[Figure]](FIGURE/GMN0616.GIF)
To perform a trace, select TRACE ON and then click the OK button. Note that the trace continues until you select TRACE OFF and click the OK button.
For the log file name, always specify the absolute path name of the file.
For the data size, specify the output size, in bytes, of the void*-type data dump.
When the multi-connection facility is used, the following environment variables cannot be set for each connection destination. These environment variables become invalid even if they are registered to a normal file or registry and specified in each connection destination.
