HP drivers compatibility with Red Hat Enterprise Linux 7 kernel

Hi DBAs,

Recently I installed   Red Hat Enterprise Linux  7.3  on HP Hardware and applied latest redhat patches which upgraded the kernel version to 7.4 . I came across issue where I was getting hpdsa HP driver error while booting with latest kernel after applying latest Red Hat patches because the kernel version got updated to latest 7.4 kernel due to this issue Red Hat Linux Operating system was not booting up and was giving error. After doing some research and with assistance of Red hat Support I was able to figure and resolve this issue. Sharing details of the Error and Steps followed to resolve this issue.

Kernel details:


Error:Unable to handle kernel NULL pointer dereference 
                                           Modules linked  hpdsa


Observation and Resolution:

 There is a problem with Raid driver for Gen9 Server . We had installed the driver during installation but the module was close driver from HPE and it needs to be upgraded accordingly. Our updated kernel was not kernel for Red Hat 7.3 but is was for Redhat 7.4


Red Hat Enterprise Linux 7.0 (Maipo), June 10,2014   ; 4 years ago, uses Linux Kernel 3.10.0-123
Red Hat Enterprise Linux 7.1, (Maipo), March 5,2015 ; 3 years ago, uses Linux Kernel 3.10.0-229
Red Hat Enterprise Linux 7.2 (Maipo), Nov 19,2015 ;   3 years ago, uses Linux Kernel 3.10.0-327
Red Hat Enterprise Linux 7.3 (Maipo), Nov   3,2016 ; 2 years ago, uses Linux Kernel 3.10.0-514
Red Hat Enterprise Linux 7.4 (Maipo), Aug  1,2017 ; 1 years ago, uses Linux Kernel 3.10.0-693

Latest driver for HP can be found in below location:

https://downloads.linux.hpe.com/SDR/repo/spp-gen9/2018.03.0/packages



As we can see for 7.4 kernel we have a different driver available

Each Red Hat release has one kernel version and only fixes so from 3.10.0-514 they will make only 3.10.0-514.XYX ,so same kernel module will work but if you upgrade to newer Red Hat Kernel (7.4) than new kernel module is required.

Download the driver module kmod-hpdsa-1.2.10-123,rhel7u4.x86_64.rpm and copy to the server.
Boot the RHEL server with older version of  kernel(Red Hat Enterprise Linux 7.3 (Maipo), Nov   3,2016 ; 2 years ago, uses Linux Kernel 3.10.0-514) which is working fine and install the rpm as below:

rpm –ivh packagename.rpm
rpm -ivh  kmod-hpdsa-1.2.10-123,rhel7u4.x86_64.rpm

After successfully installing RPM verify the kernel version, HP Driver module version and reboot the server. Use below commands for validations.

#rpm -q kernel
#rpm -a|grep -i kernel*
#modinfo hpdsa
# init 6

Choose below kernel to boot the server:

Red Hat Enterprise Linux 7.4 (Maipo), Aug  1,2017 ; 1 years ago, uses Linux Kernel 3.10.0-693

Now it will work and the issue is resolved.

Enjoy Learning and Working on Red Hat Linux ...

Thanks,

clrg comand for Oracle Apps DBA in Oracle SuperCluster Environment

Hi All,

In Oracle SuperCluster Environment we use important command 'clrg' for stopping and Starting of Oracle Web tier and Concurrent Manager Services.

clrg stands for clresourcegroup, which assist us to manage resource groups for Oracle Solaris Cluster data services or  on Oracle SuperCluster Environment

Below are commands we use on Oracle Apps nodes as 'root' Operating system user on Solaris Environment where Oracle Supercluster is running:

In order to:
·         Stop application on only application server 1 to stop all opmn and concurrent manager services on apps server1 and server2 completely.

  # clrg offline opmn-rg
  # clrg offline cm-rg


 Start application on only application server 1:

   # clrg online cm-rg
  #  clrg online opmn-rg

·         Stop application on one application server (i.e Apps Server 1 or Apps Server 2):

 # clrg offline –n nodename opmn-rg
# clrg offline –n nodename cm-rg

·         Start application on one application servers (i.e Apps Server 1 or Apps Server 2):

 # clrg online –n nodename cm-rg
 # clrg online –n nodename opmn-rg

·         Monitor the cluster resources
 # clrg status
 # clrs status

·         Monitor the full cluster staus:

# cluster status

Example :

root@erpclusterapps1:~# cluster status

=== Cluster Resource Groups ===

Group Name     Node Name          Suspended     State
----------     ---------          ---------     -----
scalmnt-rg     erpclusterapps2     No            Online
               erpclusterapps1     No            Online

cm-rg          erpclusterapps2     No            Online
               erpclusterapps1     No            Online

opmn-rg        erpclusterapps2     No            Online
               erpclusterapps1     No            Online


=== Cluster Resources ===

Resource Name     Node Name          State      Status Message
-------------     ---------          -----      --------------
erp-fs-rs         erpclusterapps2     Online     Online
                  erpclusterapps1     Online     Online

cm-rs             erpclusterapps2     Online     Online - Service is online.
                  erpclusterapps1     Online     Online - Service is online.

cmlsr-rs          erpclusterapps2     Online     Online - Service is online.
                  erpclusterapps1     Online     Online - Service is online.

opmn-rs           erpclusterapps2     Online     Online
                  erpclusterapps1     Online     Online

Hope it is useful. Enjoy learning Apps DBA on Exadata / Supercluster Environment


Thanks,

Clonning Oracle EBS Applications and Database

Hi DBAs,

Clonning is one of the regular tasks done by Apps DBA & DBAs. I have done lot of clonning
in various ways,below is one such task.Hope you will like it. Theses steps are applicable for
Oracle EBS Release 12.1.3 and Database version is 11.2.0.4.0

Step 1: Source Environment Preparation Steps:
Run adpreclone.pl on DB and Application Tier
DB Tier:
cd $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME
perl adpreclone.pl dbtier
Application Tier:
cd $ADMIN_SCRIPTS_HOME
perl adpreclone.pl appsTier

Step 2: Take Backup of Database and Applications:
Database:
Use the below script to take full rman backup taken can be used for cloning on source Environment.
run
{
configure device type disk parallelism 6;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
allocate channel c3 device type disk;
allocate channel c4 device type disk;
allocate channel c5 device type disk;
allocate channel c6 device type disk;
backup full database format '/backup/rman/EBSTEST/juneDD/EBSTEST_Full%d_%s_%T_%U' database;
backup format '/backup/rman/EBSTEST/juneNN/EBSTEST_ARCH%d_%s_%T_%U' archivelog all;
backup current controlfile format '/backup/rman/EBSTEST/juneNN/control%d%t_control.ctl';
release channel c1;
release channel c2;
release channel c3;
release channel c4;
release channel c5;
release channel c6;
}

Note: Replace DD with the date or any other directory name as required.

Application Tier:
Compress the top directories using the below commands:
tar –cf /backup/PROD/appl/appsst<date>.tar /erpapp/apps/apps_st
tar –cf /backup/PROD/appl/techst<date>.tar /erpapp/apps/tech_st


Step 3:Copy and Extract Files to DEV Node:

Copy the appsst.tar and techst.tar to respective locations in DEV and extract using:
tar –xf appsst.tar
tar –xf techst.tar

Step 4:Preparing DEV for Refresh:

a) Shutdown Applications and Database Services
b) Take DEV backup if required
c) Take a backup of pfile
d) sqlplus ‘/as sysdba’
startup mount
alter system enable restricted session;
drop database;
e) cp initTESTEBS.ora initEBSTEST.ora
vi initEBSTEST.ora
db_name=EBSTEST
control_files='+DATA/TESTEBS/CONTROLFILE/ctr<new1>.dbf','+DATA/TESTEBS/CONTROLFILE/ctr<new2>.dbf ','+DATA/TESTEBS/CONTROLFILE/ctr<new3>.dbf '
export ORACLE_SID=EBSTEST
startup nomount


Step 5: Restore and Recover Database
Restore controlfile from backup of source Database which should be copied using scp to the
target DB server.

rman target /
restore controlfile from ‘<PATH OF CONTROLFILE BACKUP>’
alter database mount;
crosscheck backup;
delete expired backup;
crosscheck backup;
list backup;
Note:Find the latest sequence and thread number and use them in place of “SEQUENCE” and “N” in below script.

run
{
set until sequence <SEQUENCE> thread <N>;
configure device type disk parallelism 6;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
allocate channel c3 device type disk;
allocate channel c4 device type disk;
allocate channel c5 device type disk;
allocate channel c6 device type disk;
set newname for database to '+DATA';
restore database;
switch datafile all;
recover database;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
release channel c5;
release channel c6;
}
exit;

This completes the database restore and recovery.

Step 6: Configuring DEV Database

Now the Database is in Mount State with EBSTEST name.
Change the redolog file names of Thread 1 to +RECO
a. alter database rename file ‘+RECO/EBSTEST…’ to ‘NEW PATH’
alter database backup controlfile to trace
shut immediate
b. Rename trace file to ctrl.sql
vi ctrl.sql
Change “REUSE” to “SET”
Change “EBSTEST” to “EBSDEV”
Change “noresetlogs” to “resetlogs”
Change “archivelog” to “noarchivelog”
c. cp initEBSTEST.ora initEBSDEV.ora
Change db_name=AMDEV in initEBSDEV.ora
d. export ORACLE_SID=EBSDEV
e. sqlplus ‘/as sysdba’
@ctrl.sql
alter database open resetlogs;
f. Run Autoconfig

This completes the Database Cloning

Before starting cloning, modify FND Template as below:
cd $FND_TOP/admin/driver/fndtmpl.drv
txkWfClone.sh INSTE8_SETUP to txkWfClone.sh INSTALL_SETUP

Step 7:Clone Application Tier:
cd /erpapp/apps/apps_st/comn/clone/bin
perl adcfgclone.pl appsTier
Answer the prompts and do not start services once apply is complete

Step 8:Take a backup of context file 
vi $CONTEXT_FILE
Change the load balancing related parameters

Step 9:Start the EBS applications
5.11 adstrtal.sh apps/<password>

Post Cloning Steps:

a) Change logo
Upload the below logo to $OA_MEDIA/COMPLOGO_SC.jpg

b) Run the Data masking script:

 c) Cancel the Running/Pending Concurrent Requests
UPDATE fnd_concurrent_requests
SET phase_code = 'C', status_code = 'X'
WHERE status_code IN ('Q','I')
AND requested_start_date > SYSDATE
AND hold_flag = 'N';

UPDATE fnd_concurrent_requests
SET phase_code = 'C', status_code = 'X'
WHERE phase_code IN ('R','P');
Commit;

d) Disable Workflow Notification Mailer. Set the override address from OAM. Purge pending notifications.

UPDATE WF_NOTIFICATIONS
SET MAIL_STATUS = 'SENT', STATUS = 'CLOSED'
where status in ('OPEN', 'CANCELED')
and mail_status in ('MAIL', 'INVALID');

sqlplus apps/appspwd@db @$FND_TOP/patch/115/sql/wfntfqup.sql apps appspwd applsys

update wf_roles set NOTIFICATION_PREFERENCE=’DISABLED’,email_address=null;

e) Update per_all_people_f set email_address=null where email_address is not null;

f) Change the profile options:
Site Name to “DEV Instance”
Java Color Scheme to a color which is not same as PROD

e) Change the system, apps, sysadmin, xxcomp passwords
f) Add tempfile to Temp Tablespace
g) Change the URLs previously in Context File configured for Load Balancing in PROD and run autoconfig.

s_external_url http://testebs.COMPLOGO.ae:8000
s_login_page http://testebs.COMPLOGO.ae:8000/OA_HTML/AppsLogin
s_webentryhost testebs
s_webentrydomain COMPLOGO.ae

h) Update the Node information for all Concurrent Managers from Concurrent Manager Define to current node name and restart concurrent managers using adcmctl.sh
i) DEACTIVATE “Periodic Alert Scheduler”
j) Update Discoverer URL in Context File ( Application Tier - s_disco_url):
http://customsoadev.COMPLOGO.ae:7777
k) erpuat@COMPLOGO.ae shall be used as the Email ID for notifications in case if WF Notification Mailer is being enabled

Hope you followed clonning steps. Enjoy Apps DBA tasks.

Thanks,
