====== Patch GRID_HOME ======


== Grid Patch 19.28 ==

You must use the OPatch utility version 12.2.0.1.46 or later to apply this patch.

  * Database: 37960098
  * Grid: 37957391 
    * opatch 12.2.0.1.46 or later (http://updates.oracle.com/ARULink/PatchDetails/process_form?patch_num=6880880)
    * a shared location on Oracle ACFS only needs to be unmounted on the node where the Grid home is being patched.

== Prerequisites ==
  * unzip Grid patch
<code BASH>
[root@oracle2]# mkdir /u01/Downloads/GI_19.28.0.0/
[root@oracle2]# cd /u01/Downloads/GI_19.28.0.0/
[root@oracle2]# unzip /mnt/mdl-nas3/3-Software/6-BDD/ORACLE/Oracle19c/Patch/LINUX/DATABASE_19.28.0.0.0/p37957391_GI_192800_Linux-x86-64.zip
[root@oracle2]# chown grid:oinstall /u01/Downloads/GI_19.28.0.0/ -R
</code>

== Step 1 – Check the OPatch Version ==

<code BASH>
[root@oracle2]# cd /u01/app/19c/grid_home/
[root@oracle2 grid_home]# OPatch/opatch version
OPatch Version: 12.2.0.1.48
OPatch succeeded.
</code>

== Step 2 – Run Conflict Checks (todo to every subpatches, in the patch number order) ==

<code BASH>
[grid@oracle2 ~]$ /u01/app/19c/grid_home/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/Downloads/GI_19.28.0.0/37957391/37960098

[grid@oracle2 ~]$ /u01/app/19c/grid_home/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/Downloads/GI_19.28.0.0/37957391/37962946

[grid@oracle2 ~]$ /u01/app/19c/grid_home/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/Downloads/GI_19.28.0.0/37957391/37962938

[grid@oracle2 ~]$ /u01/app/19c/grid_home/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/Downloads/GI_19.28.0.0/37957391/38124772

[grid@oracle2 ~]$ /u01/app/19c/grid_home/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/Downloads/GI_19.28.0.0/37957391/36758186

</code>

== Step 3 – Validate System Space Availability ==

<code BASH>
echo /u01/Downloads/GI_19.28.0.0/37957391/37960098  >  /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt
echo /u01/Downloads/GI_19.28.0.0/37957391/37962946  >> /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt
echo /u01/Downloads/GI_19.28.0.0/37957391/37962938  >> /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt
echo /u01/Downloads/GI_19.28.0.0/37957391/38124772  >> /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt
echo /u01/Downloads/GI_19.28.0.0/37957391/36758186  >> /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt

/u01/app/19c/grid_home/OPatch/opatch prereq CheckSystemSpace -phBaseFile /u01/Downloads/GI_19.28.0.0/patch_list_gihome.txt
</code>

== Step 4 – Apply the 19.28 Patch Using OPatchAuto ==
opatchauto is launched as ROOT, hence it has to be applied on both RAC nodes 
<code BASH>
/u01/app/19c/grid_home/OPatch/opatchauto apply /u01/Downloads/GI_19.28.0.0/37957391/ -oh /u01/app/19c/grid_home
</code>

== Step 5 – Verify CRS and ASM Services ==
<code BASH>
crsctl stat res -t
