/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/preupgrade_fixups.sql
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/postupgrade_fixups.sql
Execute fixup scripts across the entire
CDB:
Before upgrade:
1. Execute preupgrade fixups with the below
command
$ORACLE_HOME/perl/bin/perl
-I$ORACLE_HOME/perl/lib -I$ORACLE_HOME/rdbms/admin
$ORACLE_HOME/rdbms/admin/catcon.pl -l
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/ -b preup_kardbprd
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/preupgrade_fixups.sql
2. Review logs under
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/
After the upgrade:
1. Execute postupgrade fixups with the
below command
$ORACLE_HOME/perl/bin/perl
-I$ORACLE_HOME/perl/lib -I$ORACLE_HOME/rdbms/admin
$ORACLE_HOME/rdbms/admin/catcon.pl -l /oracle/app/home/cfgtoollogs/kardbprd/preupgrade/
-b postup_kardbprd
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/postupgrade_fixups.sql
2. Review logs under
/oracle/app/home/cfgtoollogs/kardbprd/preupgrade/
