I love to ask, then answer my own questions…

problem goes away if the following is performed:

Enable AIO in AIX operating system. These are two possible ways to do this:
As root:
1. From „smitty aio”
2. Change / Show Characteristics of Asynchronous I/O
3. STATE to be configured at system restart
4. Choose „available.”
5. Execute the following command:

/usr/sbin/mkdev -l aio0

This change does not require a reboot.
Consult AIX documentation for further details on enabling AIO at Operating System.

제목: ORA-01115 ORA-01110 ORA-27091 ORA-27072 Error: 5: I/O error
문서 ID: 559697.1 유형: PROBLEM
Modified Date: 12-FEB-2009 상태: MODERATED

Applies to:

Oracle Server – Enterprise Edition – Version: 9.2.0.8
IBM AIX Based Systems (64-bit)

Symptoms

After patching the OS with Patch IBM Technology Level 6 (5300-06) or Level 7 (5300-07), the application log started reporting the following errors:

ORA-01115: IO error reading block from file <file id> (block # <block number>)
ORA-01110: data file <file id>: <file name>
ORA-27091: skgfqio: unable to queue I/O
ORA-27072: skgfdisp: I/O error
IBM AIX RISC System/6000 Error: 5: I/O error

- The errors are not reported in the alert log file.
- Running dbv against datafiles from the error messages shows no errors.
- All the mandatory OS patches are applied.
- Oracle patch for Bug 5496862 – IO READING PROBLEMS AFTER INSTALLING IBM TECHNOLOGY LEVEL 5 (5300-05) was installed before patching the OS.

Changes

Patch IBM Technology Level 6 (5300-06) or Level 7 (5300-07) was applied to the OS.

Cause

The value of maxreqs (4096) was too low. This asynchronous I/O parameter specifies the maximum number of asynchronous I/O requests that can be outstanding at any one time and has as default value 4096.

Solution

Increase maxreqs to a value greater than or equal to 8192.
Steps:
1. run aioo -a command to double check current setting for aio0 device
2. run aioo -o maxreqs=<value> to set maxreqs dynamically
3. chdev -l aio0 -a maxreqs=<value> to set the value of maxreqs permanently for next reboot
4. run aioo -a to confirm change
5. restart oracle
NOTE: Values that fixed the errors: 8192, 16384 or 32768

Linux by default requires any NFS mount to use a so called
reserved port below 1024 and AIX 4.3 does by default use
ports above 1024. You can use the nfso command to restrict
AIX to the reserved port range as follows:

nfso -o nfs_use_reserved_ports=1

 showmount -a 10.1.0.88

mount 10.1.0.88:/nas/NASDisk-00003/public /mnt/storage
 mount 10.1.0.88:/nas/NASDisk-00005/SAPDQ /mnt/storage
nfso -o nfs_use_reserved_ports=1
