3.8.6 Notes

• You can enter replies only from a JP1/IM - View that is connected to the JP1/IM - Manager specified in the HOSTNAME_JP1IM_MANAGER parameter.

• Because there is a limit to the number of reply-waiting events that can be accumulated by JP1/IM - Manager, design your operations in such a manner that this limitation is observed.

• The character encodings that can be entered from JP1/IM - View are those within the range of the ASCII character encodings (excluding the control characters). If a character encoding outside this range is entered, an error message will be displayed. In such a case, re-enter a character encodings within the permitted range.

• When the adshecho and adshread commands are executed, JP1/Base closes a TCP/IP connection with the host specified in the HOSTNAME_JP1IM_MANAGER parameter and then establishes connection using a new port.

  The port that was being used becomes unavailable for a period equal to the OS's maximum segment lifetime (MSL) 2 (seconds). If the value of MSL is large or there are only a few ports, a shortage of ports might occur.

  For this reason, set MSL, the number of JP1 events to be output during a period of MSL 2 (seconds), and the number of ports to satisfy the following condition:

  n MSL 2 3 < number-of-ports

  n: Number of JP1 events that can be output by the user-reply functionality during a period of MSL 2 (seconds)

• In UNIX, when the user-reply functionality's management daemon starts, a file with the following name is created in the spool directory to manage reply-request messages in the shared memory:

  • .adsh_mqueue

  • .adsh_mqueue_logical-host-name (applicable when the user-reply functionality's management daemon is started on a logical host)

  Do not delete this file while the user-reply functionality's management daemon is running. When the user-reply functionality's management daemon terminates, this file remains and can be reused the next time the user-reply functionality's management daemon starts.

  In HP-UX, in addition to the above file, a file with the following name is also created in the spool directory:

  • .adsh_mqueueS

  • .adsh_mqueue_logical-host-nameS (applicable when the user-reply functionality's management daemon is started on a logical host)

  Do not delete this file while the user-reply functionality's management daemon is running. The file is deleted when the user-reply functionality's management daemon terminates.

• Before you shut down the OS, terminate the user-reply functionality's management daemon or service. If there are reply-request messages still waiting for replies when the user-reply functionality's management daemon or service stops, the daemon or service will cancel these reply-request messages and then stop. If OS shutdown processing is performed, the OS might be shut down before the reply-request messages are cancelled. If this happens, the accumulated reply-waiting events will remain in JP1/IM - View.
