WARNING: aio_wait: errno = nn

Cause:

While the database server was waiting for an I/O request to complete, it generated error number nn on an operation that it was attempting to execute.

Action:

Contact IBM Technical Support at tsmail@us.ibm.com for assistance.

WARNING: Buffer pool size may cause database server to get into a locked state. Recommended minimum buffer pool size is num times maximum concurrent user threads.

Cause:

There are not enough buffers in the buffer pool. The database server could use all available buffers and cause a deadlock to occur.

Action:

Change the BUFFERS parameter in the ONCONFIG file to the number that this message recommends. For more information on the BUFFERS parameter, see BUFFERS.

warning: chunk timestamps are invalid.

Cause:

A sanity check is performed on chunks when they are first opened at system initialization. The chunk specified did not pass the check and will be brought offline.

Action:

Restore the chunk from a dbspace backup or its mirror.

Warning: unable to allocate requested big buffer of size nn

Cause:

The internal memory allocation for a big buffer failed.

Action:

Increase either virtual memory size (SHMVIRTSIZE), the size of the added segments (SHMADD), or your total shared-memory size (SHMTOTAL).
