ORAchk Health Checks For The Oracle Stack (ORACHK 2.2.4 and above)


Oracle Database 12c (12.0.1.*) and 11g (11.2.0.4) comes with new feature called RACcheck.
Although the RACcheck already exists before these releases. (In 2011 I posted about benefits of RACcheck)

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
  • Supported Platforms

  • 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)
  • AIX **
  • HPUX**
  • * 32-bit platforms not supported, no planned support for Linux Itanium
    **Requires BASH Shell 3.2 or higher to be installed

    Supported Oracle Releases

  • 10gR2
  • 11gR1
  • 11gR2
  • 12cR1
  • When to Run ORAchk

  • After initial Oracle RAC deployment
  • Before planned system maintenance
  • After planned system maintenance
  • At least once every three months
  • Install/Configure

    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.

    Download ORAchk

    Stage Location:
    It is recommended that the kit be staged and operated from a local filesystem on a single database server in order to provide the best performance possible.

    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.

    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 11.2.0.3 (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 11.2.0.3 and above as smooth as possible by automating many of the
    manual pre and post checks detailed in various upgrade related documents.

    Refer MoS Notes for more details:

    ORAchk Users Guide
    For details instructions on how to run ORAchk including troubleshooting steps, available options, etc.
