ORACLE MML Load Library

[박형석_1]

On Oracle, i use rman.
So, i want to load SBT library.
Oracle engineer told me how to compile SBT library on HP.

cc -o libobk.so +DD64 -G -I. -ldld -DORA_BSP -DHPUX skgfqsbt.c

compile was success.

But, When rman ran and tried to make channel,
error was occurred.

ORA-27211: Failed to load Media Management Library

I don't know what is wrong.
help me.

Hi,

Error: ORA-27211: Failed to load Media Management Library

The cause for this error is User-supplied SBT_LIBRARY or libobk.so could not be loaded.

i.e Call to dlopen for media library returned error. The work around will be to retry the command with proper media library. Or re-install Media management module for Oracle.

If you RDBMS version is 9i, then in Oracle9i RMAN searches for the media management library dynamically when allocating a channel. RMAN searches for the libobk.so file which does not exist in the Oracle9i environment yet.

In this case create a reference to the Media Management Library by introducing a symbolic link called $ORACLE_HOME/lib/libobk.so which points to the 3rd party Media Management Library.

Example on SUN Solaris with Legato Storage Manager (LSM):

cd $ORACLE_HOME/lib
ln -s /usr/lib/liblsm.so libobk.so

I hope this helps.
