ways to enable or disable or bypass maintenance mode during patching

1. run sql script

sqlplus -s apps/appspass @$AD_TOP/patch/115/sql/adsetmmd.sql ENABLE
sqlplus -s apps/appspass @$AD_TOP/patch/115/sql/adsetmmd.sql DISABLE

2. interactive adadmin

adadmin->(5) Change Maintenance Mode->(1) Enable Maintenance Mode

adadmin->(5) Change Maintenance Mode->(2) Disable Maintenance Mode


3. noninteractive adadmin

3.1 create defaults file:

adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/admydefaults.txt

(for email notification prompt, need to answer No. answer Yes to give an email address)

(the passwords for system and applsys are hashed).

3.2 use the defaults file:

adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/admydefaults.txt \ menu_option=DISABLE_MAINT_MODE interactive=n

adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/admydefaults.txt \ menu_option=ENABLE_MAINT_MODE interactive=n


4. adpatch options=hotpatch to bypass maintenance mode

Need to follow Oracle Support to use this options while the system is up. For other patches, shutdown application first and then use hotpatch option to apply patches without enable maintenance mode.
