Brief of RACcheck.
..... RACcheck - The Oracle RAC Configuration Audit Tool
RACcheck is designed to audit vital configuration settings for the Oracle Database, single instance databases, as well as Oracle Real Application Clusters (Oracle RAC) databases. It also includes checks for Oracle Clusterware, Oracle Automatic Storage Management (Oracle ASM) and Oracle Grid Infrastructure.
RACcheck provides best practices recommedations considering the whole stack, including Maximum Availability Architecture (MAA) configurations and is therefore the ideal tool for regular health checks as well as pre- and post-upgrade best practices assessments.
Now Oracle replace/renamed Oracle RACcheck to ORAchk.
ORAchk- Health Checks for the Oracle Stack
ORAchk replaces the popular RACcheck to support a wider range of products. ORAchk version 2.2.4 is now available for download and includes the following key features:
RACcheck renamed to ORAchk
ORAchk daemon auto-start mode after node reboot (init integration)
Merge multiple ORAchk collection reports
Upload of installed patches to database
Collection Manager for ORAchk, RACcheck and Exachk (Document 1602329.1)
ORAchk signature file in /tmp on all nodes to verify last ORAchk run
New checks and bug fixes, including
30 Oracle Ebusiness AP module data integrity checks
12 new Database checks
8 new Solaris system checks
Linux x86-64* (Enterprise Linux, RedHat and SuSE 9, SuSE 10 & SuSE 11)
Oracle Solaris SPARC (Solaris 10 and 11)
Oracle Solaris x86-64 (Solaris 10 and 11)
* 32-bit platforms not supported, no planned support for Linux Itanium
**Requires BASH Shell 3.2 or higher to be installed
Supported Oracle Releases
When to Run ORAchk
After initial Oracle RAC deployment
Before planned system maintenance
After planned system maintenance
At least once every three months
It is recommended to run the tool as the database software owner (e.g. oracle). The user may run the tool as the Grid Infrastructure software owner (e.g. grid) and it will collect the same data but database credentials must manually be supplied to perform the database related audit checks. Typically when run as oracle the customer will have OS authentication set up for the oracle database software owner and the database login credentials will not be needed.
17 of the included audit checks require root privileged data collection . If sudo is not configured or the root password is not available, audit checks which require root privileged data collection can be skipped.
1. Enter 1 if you will enter root password for each host when prompted
2. Enter 2 if you have sudo configured for oracle user to execute root_orachk.sh script
3. Enter 3 to skip the root privileged collections
4. Enter 4 to exit and work with the SA to configure sudo or to arrange for root access and run the tool later.
Please indicate your selection from one of the above options for root access[1-4]:- 2

ORAchk Other Useful Options Not Covered Here
Using ORAchk Silently
ORAchk can be optionally run in “silent” or “non-interactive” mode in order to enable scheduling and automation
Is required only if customer does not want to use orachk daemon functionality.
Using ORAchk Daemon Mode Operation
This functionality permit non-interactive (batch or silent mode) execution on a regular interval.
When running ORAchk in daemon mode, the most recent and next most recent (if any) collection reports are automatically compared. If the mail address is configured a summary will be emailed along with attachments for the reports and the comparison report.
Report Comparisons with ORAchk
ORAchk has the ability to perform report comparisons between 2 ORAchk reports.
This allows for trending of Success Factor and Best Practice changes over time, after planned maintenance, etc within a user friendly HTML report.
ORAchk in Upgrade Readiness Mode
ORAchk can be used to obtain an automated 184.108.40.206 (or above) Upgrade Readiness Assessment.
The goal of the ORAchk Upgrade Readiness Assessment is to make the process of upgrade planning for Oracle RAC and Oracle Clusterware target versions 220.127.116.11 and above as smooth as possible by automating many of the
manual pre and post checks detailed in various upgrade related documents.

Recently installed Oracle Database on AIX 6.1 system I’ll post here the problems and solutions encountered during implementation.
As problems arise I’ll post new problems and solutions.
Installing Oracle Database 11gR2 (18.104.22.168.0) on AIX fail at Prerequisites Check. Missing : IZ97457 and IZ89165
IZ97457: SEA/VIO CLIENT HANG – INTERRUPTS DO NOT REACH THE TRUNK ADAPTER APPLIES TO AIX 6100-05
IZ89165: BIND64 CORES WITH -BLAZY OPTION ON 61TL6 APPLIES TO AIX 7100-00
An Authorized Program Analysis Report, or APAR, is a formal report to IBM development of a problem caused by a suspected defect in a current release of an IBM program.
IBM release an new APAR number for each TL.
IZ97457: SEA/VIO CLIENT HANG - INTERRUPTS DO NOT REACH THE TRUNK ADAPTER APPLIES TO AIX 6100-05
5300-11 - use AIX APAR IZ98424

6100-04 - use AIX APAR IZ97605
6100-05 - use AIX APAR IZ97457
6100-06 - use AIX APAR IZ96155
7100-00 - use AIX APAR IZ97035
IZ89165: BIND64 CORES WITH -BLAZY OPTION ON 61TL6 APPLIES TO AIX 7100-00
6100-03 - use AIX APAR IZ89304
6100-04 - use AIX APAR IZ89302
6100-05 - use AIX APAR IZ89300
6100-06 - use AIX APAR IZ89514
7100-00 - use AIX APAR IZ89165
In your case Oracle OUI don’t know if APAR is installed because it check only one APAR Number.
So see this example:
root:/> oslevel -r
#### Check if apar number IZ89165 is installed.
### Using APAR number required by Oracle
root:/> instfix -a -i |grep IZ89165
#### nothing found
root:/> instfix -a -i |grep IZ89514
IZ89514 Abstract: Linking with -blazy and -G or -brtl causes core dump
IZ89514 Symptom Text:
All filesets for IZ89514 were found.
So, just Ignore warning, if you make sure which APAR already installed.
Install Oracle 10g R2 on AIX 6.1 and the installation hangs at 83% in Prereqs Check.
I have installed the 22.214.171.124 Grid Infrastructure in different User and directory on the same system.
Oracle Grid Infrastructure for Standalone allows you to install the binaries to User (eg grid) different operating system User (eg Oracle) Oracle Database.
This helps in the administration and security. But I do not recommend doing this because many problems are still solved with workaround.
To solve this problem use note on MOS:
