Oracle RACcheck - RAC Configuration Audit Tool

This blogpost provides details of the RACcheck (RAC Configuration Audit Tool) . I have tried to run this wonderful tool on my RAC database on my laptop and wanted to share the output of the tool received, The detailed output from this tool is self explanatory and requires no narration. This tool is brought by RAC assurance team of Oracle. The tool is designed to audit various important configuration settings within an RAC System. The tool audits configuration settings within the following categories:

1. OS kernel parameters
2. OS packages
3. Many other OS configuration settings important to RAC.
4. CRS/Grid Infrastructure
5. RDBMS
6. ASM
7. Database parameters
8. Many other database configuration settings important to RAC.
9. 11.2.0.3 Upgrade Readiness assessment

The scope of the RACcheck health assessment tool is RAC databases servers, Grid Infrastructure, RAC databases, hardware, Operating System and RAC software. Starting with RACcheck 2.2.0, RACcheck functionality has been extended to Oracle Single Instance Databases, Oracle Restart Systems as well as RAC One node configurations.

CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to /u01/grid/oracle/product/11.2.0/grid_1?[y/n][y]

List of running databases registered in OCR
1. RAC
2. None of above

Select databases from list for checking best practices. For multiple databases, select 1 for All or comma separated number like 1,2 etc [1-2][1].

-------------------------------------------------------------------------------------------------------

74 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_raccheck.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[1-4][1]:- 1


*** Checking Best Practice Recommendations (PASS/WARNING/FAIL) ***




Log file for collections and audit checks are at

/home/oracle/RACCHECK/raccheck_082113_224408/raccheck.log

Running raccheck in serial mode because expect(/usr/bin/expect) is not available to supply root passwords on remote nodes


NOTICE:  Installing the expect utility (/usr/bin/expect) will allow raccheck to gather root passwords at the beginning of the process and execute raccheck on all nodes in parallel speeding up the entire process. For more info - http://www.nist.gov/el/msid/expect.cfm.  Expect is available for all major platforms.  See User Guide for more details.
