Attention all installation gurus/hacks...
I'm looking for suggestions, experiences, and best practices on safely
applying Oracle patches and minimizing database down time. By way of example
let's say we're going from server version 8.1.6.0.0 to 8.1.6.3.0. Let's also
say we're going to apply the 8.1.6.3.0 interMedia patchset. Here are some
generalized steps:
1) Uncompress/untar the patchsets to a staging area.
2) Whilst the database is up, run the installer to install all the requisite
software to a new $ORACLE_HOME.
old $ORACLE_HOME = /u01/app/oracle/product/8.1.6
new $ORACLE_HOME = /u01/app/oracle/product/8.1.6.3.0
export ORACLE_HOME=/u01/app/oracle/product/8.1.6.3.0
/u01/app/oracle/product/8.1.6/bin/runInstaller
3) Whilst the database is up, copy interMedia executables and libraries to
the appropriate sub-directores of the new $ORACLE_HOME.
4) Whilst the database is up, run the installer to install the new patches
pointing it to the staging area in step 1.
5) Shut everything down. Shutdown Oracle dependent processes like ctxsrv.
Shutdown the listener. Shutdown the database:
alter system checkpoint;
shutdown abort;
startup;
shutdown immediate;
Do not make any cold backups. Depend on RMAN backups for recovery should
anything go awry.
6) Relink oracle.
make -f ins_rdbms.mk ioracle
7) Change the PATH and oratab to reflect the new $ORACLE_HOME.
8) Startup the database, listener, and ctxsrv to make the application
available.
9) With everything up, run the SQL scripts to complete the patch:
@catalog.sql
@catproc.sql
@catrep.sql
create or replace java system;
-- interMedia stuff
@dr0pkh.sql
@dr0plb.sql
@dr0type.plb
10) scan/recompile invalid objects.
HERE'S THE PIVOTAL ISSUE...
Depending on resources step 9 could take about two hours. What are the
effects of executing this while the application is running? Comments and
suggestions?
TIA,
Steve Orr
