Operating Systems AIX Interoperability Oracle Clusterware - PowerHA/HACMP Post 302537476 by bakunin on Friday 8th of July 2011 10:02:15 AM

Having worked for some time on this issue I'd like to share my findings.

The initial issue was a system not being able to boot after Clusterware was installed. We found the following:

Clusterware installs a cluster daemon "ohasd" which is started in /etc/inittab in runlevel 2. Unfortunately the starting script never comes back if anything goes wrong.

As it is with usual HACMP-installations the Oracle binaries are being installed on a VG which is itself part of a HACMP-Resource group. Therefore the filesystem where the ohasd daemon is expected to be will not be there at system start (but only after cluster start and activation of the resource group).

The solution was to take the start routines and everything else installed by Oracle out of the systems start routines (inittab, rc-scripts) and put it in the start-scripts of the resource group. I will provide you with a list of what exactly we did when time permits. Still, ohasd, which effectively prevented system boot, was the biggest issue we encountered.

I hope this helps someone.

NAME
Jifty::DBI::Handle::Oracle - An oracle specific Handle object SYNOPSIS
DESCRIPTION
This module provides a subclass of Jifty::DBI::Handle that compensates for some of the idiosyncrasies of Oracle. METHODS
connect PARAMHASH: Driver, Database, Host, User, Password Takes a paramhash and connects to your DBI datasource. database_version Returns value of ORA_OCI constant, see "Constants" in DBD::Oracle. insert Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted. build_dsn PARAMHASH Takes a bunch of parameters: Required: Driver, Database or Host/SID, Optional: Port and RequireSSL Builds a dsn suitable for an Oracle DBI connection blob_params column_NAME column_type Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type. The current Oracle implementation only supports ORA_CLOB types(112). apply_limits STATEMENTREF ROWS_PER_PAGE FIRST_ROW takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW; distinct_query STATEMENTREF takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.
