035
Explanation
During system initialization, the system could not find an entry point in the nucleus. The system
loaded one of the following:
- An incomplete nucleus
- An incomplete I/O configuration
- Both an incomplete nucleus and an incomplete I/O configuration
System action
The system enters wait state X'035'. The system places message IEA084W in the initial program load (IPL) write to operator (WTO) buffer.
Operator response
Do the following as soon as possible to find the WTO buffer and locate message IEA084W in the
buffer. Do not write a stand-alone dump before doing this procedure, since the dump might overlay
storage.
- Using the hardware Alter/Display facility, read the real address in central storage at X'14'. This address points to the IPL diagnostic area.
- Add X'28' to the address at real X'14', and also read this as a real address in central storage. The result is the 31-bit virtual address of the IPL vector table (IVT). Henceforth, all addresses are 31-bit virtual and you must switch to displaying Primary Virtual Storage to display remaining storage locations.
- Add X' E0' to the IVT address. The result is the 31-bit address of the IVTMQHP field. IVTMQHP contains the address of the message queue header (MQH).
- MQH + X'0' contains the address of the oldest message queue element (MQE) available. The message text for the oldest MQE begins at MQE + X'8'.
- Use MQE + X'0' of the oldest MQE to find the MQE of the next oldest message. Again, the message text for this MQE begins at MQE + X'8'.
- Repeat this sequence (using MQE + X'0' of the current MQE to locate the next MQE), until the message text for the appropriate message is displayed.
System programmer response
Do the following:
- Look in the stand-alone dump for message IEA084W. Note the entry point given in the message text.
- Use the IEHLIST program to print the SYS1.NUCLEUS directory.
- Search problem reporting databases for a fix for the problem. If no fix exists, call the IBM® Support Center. Provide the stand-alone dump and the SYS1.NUCLEUS directory listing.
