3. Creating an HDLM Environment
265
„ If the Oracle command
oracleasm
is executed for HDLM devices, the
KAPL05023-E message might be output to syslog.
If the following message indicating the successful completion of the
oracleasm
command is output after this message, there is no problem with HDLM operation.
oracleasm: succeeded
„ If you use HDLM with Oracle RAC 10g or Oracle RAC 11g and use ASMLib of
Oracle RAC 10g or Oracle RAC 11g, you must change the settings for the
ASMLib configuration file.
After installing ASMLib, do the following for each node:
1.
Execute the following command to create the ASMLib configuration file:
# /etc/init.d/oracleasm configure
2. Open the ASMLib configuration file (
/etc/sysconfig/oracleasm
).
3. Change the
ORACLEASM_SCANORDER
line as follows:
ORACLEASM_SCANORDER ="sddlm"
If an ASM disk defined in an HDLM device already exists, perform this
procedure, and then restart all the nodes.
This step must be done to enable the settings.
„ If you use HDLM with Oracle RAC 11g Release 2, shared file systems, which are
created by using ADVM (ASM Dynamic Volume Manager) or ACFS (ASM
Cluster File System), cannot be used for the archived REDO log file area.
