Problems during initialization of HCD

If a problem occurs during initialization, HCD does one of the following:

• Issues a message and continues the initialization
• Terminates the initialization

Whether the initialization of HCD continues or terminates depends on the error that is encountered as explained in the following.

Initialization continues

If a UIM service routine encounters an error during initialization, HCD works without this UIM. HCD pops up messages on the user’s terminal to inform the user that messages were written to the message log.

Use the option List Installed UIMs to display the panel "Installed UIMs". On this panel, the UIM is marked as in error. (Refer to Query installed UIMs.)

If you do not have access to any UIM, check if your UIMs are correctly installed. In the HCD profile you can specify the name and volume serial number of the library that contains the UIMs (see Defining an HCD profile). If you do not specify a name in the profile, SYS1.NUCLEUS is assumed as default names for the UIMs.

Initialization is terminated

The initialization is terminated either with an abend or with a message.

In case of an abend, the dialog:

• Pops up message CBDA040I on the user’s terminal. The message informs the user that HCD has abnormally terminated.
• Puts message CBDA050I with abend code '00F' in the message log. The message also provides a reason code.
• Puts the message that is issued by a UIM service routine in the message log.

If an error is encountered in a UIM and if SYSUDUMP is allocated, an HCD abend '00F' is forced to provide a dump at the point where the error was detected.

Message CBDA041I

Means that HCD is not able to find the UIMs. If this message is issued during initialization using the "CIT" variable, make sure that the UIMs are installed in SYS1.NUCLEUS.

Table 25 and Table 26 show what the search argument and the problem data could look like.
