11G 新特性 --使用runInstaller 进行RELINK

I ) Oracle 11gR2 has two methods of relinking all product binaries in a home

1) Traditional relink with 'all' option only

The first method is the normal running the $ORACLE_HOME/bin/relink script, which now only accepts the‘all’ parameter (no other parameters are accepted)

% $ORACLE_HOME/bin/relink all
% $ORACLE_HOME/bin/relink ( By default it takes the 'all' parameter )

Note :  ‘Relink all’ is provided for backward compatibility. 

2) relink using runInstaller 

This runs the command:
 

  -relink : For performing relink actions on the oracle home
         Usage: -relink -maketargetsxml  [-makedepsxml ] [name=value]

Example :
$ORACLE_HOME/oui/bin/runInstaller -relink -waitForCompletion -maketargetsxml  $ORACLE_HOME/inventory/make/makeorder.xml  -logLocation $ORACLE_HOME/install ORACLE_HOME=$ORACLE_HOME > $ORACLE_HOME/install/relink.log 2>&1

II) Relink log location 

Case 1 
 If  relink is performed using OUI then  "$ORACLE_HOME/install/relink.log" is not created by default. 

To send the relink  output to $ORACLE_HOME/install/relink.log we need to redirect the output explicitly.

$ORACLE_HOME/oui/bin/runInstaller -relink -waitForCompletion -maketargetsxml $ORACLE_HOME/inventory/make/makeorder.xml -logDir $ORACLE_HOME/install ORACLE_HOME=$ORACLE_HOME > $ORACLE_HOME/install/relink.log 2>&1

Case 2 
In case of  " relink all " command, it always creates a new log file with a name "relink.log" and it will not append log information to the existing relink log file . The previous log will be saved with a timestamp ( Ex: relinkActions2009-09-14_09-01-10-PM.log )
