Oracle Automatic Storage Manager Disk Discovery, Oracle ASM Disk Discovery

Disk discovery is the mechanism used to find the operating system names for disks ASM can access. It is used to find all the disks that comprise a disk group to be mounted, the disks an administrator wants to add to a disk group, or the disks the administrator might consider adding to a disk group.
How A Disk is Discovered ?
While an ASM instance is initialized, ASM discovers and examines the contents of all of the disks that are in the paths that we designated with values in the ASM_DISKSTRING initialization parameter.
Disk discovery also occurs when:
1) Run the ALTER DISKGROUP…ADD DISK and ALTER DISKGROUP…RESIZE DISK commands
2) Query the V$ASM_DISKGROUP and V$ASM_DISK views :
What happens after ASM discovers a disk?
After ASM successfully discovers a disk, the disk appears in the V$ASM_DISK view

Delivered by FeedBurner

Disks that belong to a disk group, that is, disks that have a disk group name in the disk header, show a status of MEMBER in v$asm_Disk
Disks that were discovered, but that have not yet been assigned to a disk group, have a status of either CANDIDATE or PROVISIONED
The PROVISIONED status implies that an additional platform-specific action has been taken by an administrator to make the disk available for ASM. For example, on Windows computers, the administrator might have used asmtool or asmtoolg to stamp the disk with a header.
On Linux computers, the administrator might have used ASMLIB to prepare the disk for ASM.
The following SQL query shows one candidate and six member disks:
SQL>SELECT name, header_status, path FROM V$ASM_DISK;
NAME HEADER_STATUS PATH
——— ————- ———————
CANDIDATE /dev/rdsk/disk07
DISK06 MEMBER /dev/rdsk/disk06
DISK05 MEMBER /dev/rdsk/disk05
DISK04 MEMBER /dev/rdsk/disk04
DISK03 MEMBER /dev/rdsk/disk03
DISK02 MEMBER /dev/rdsk/disk02
DISK01 MEMBER /dev/rdsk/disk01
7 rows selected.
Disk Discovery Rules :
The rules for discovering ASM disks are as follows:
1) ASM can discover up to 10,000 disks (i.e) if more than 10,000 disks match the ASM_DISKSTRING initialization parameter, then ASM discovers only the first 10,000
2) ASM only discovers disks that contain a partition table. ASM does not discover a disk that contains an operating system partition table, even if the disk is in an ASM disk string search path and ASM has read and write permission for the disk
3) When adding a disk, the FORCE option must be used if ASM recognizes that the disk was managed by Oracle. Such a disk appears in the V$ASM_DISK view with a status of FOREIGN. In this case, we can only add the disk to a disk group by using the FORCE keyword
In addition, ASM identifies the following configuration errors during discovery:
1) Multiple paths to the same disk
In this case, if the disk is part of a disk group, then disk group mount fails. If the disk is being added to a disk group with the ADD DISK or CREATE DISKGROUP command, then the command fails. To correct the error, adjust the
ASM_DISKSTRING value so that ASM will not discover multiple paths to the same disk. Or if we are using multipathing software, then ensure that we include only the pseudo-device name in the ASM_DISKSTRING value.
2) Multiple ASM disks with the same disk header
This can be caused by having copied one disk onto another. In this case, the disk group mount operation fails.
Improving Disk Discovery Time :
The value for the ASM_DISKSTRING initialization parameter is an operating system–dependent value that ASM uses to limit the set of paths that the discovery process uses to search for disks.
When a new disk is added to a disk group, each ASM instance that has the disk group mounted must be able to discover the new disk using its ASM_DISKSTRING.
In many cases, the default value (NULL) is sufficient. Using a more restrictive value might reduce the time required for ASM to perform discovery, and thus improve disk group mount time or the time for adding a disk to a disk group.
Oracle might need to dynamically change the ASM_DISKSTRING before adding a disk so that the new disk will be discovered through this parameter.
The default value of ASM_DISKSTRING might not find all disks in all situations. If our site is using a third-party vendor ASMLIB, then the vendor might have discovery string conventions that we must use for ASM_DISKSTRING.
If our installation uses multipathing software, then the software might place pseudo-devices in a path that is different from the operating system default.

PMP aspirant should understand quality clearly

As a PMP aspirant you will have to learn more on quality management that starts with quality plan creation that comes as part of planning process group, performing quality assurance that is included in execution process group, performing quality control that is part of monitoring and control process group.
Now, if you are preparing for PMP exam first understand the quality definition clearly.
What does a quality mean for pmp aspirant?
As per PMBOK, quality is the degree to which project deliverable meets requirements. This is a relative term and should be noted that quality totally depends on requirements.
Now, comes two essentially important document on requirements, scope statement and requirements documentation
Scope statement – scope of the project including what is expected as deliverable is defined in scope
Requirements documentation – What is required as part of the deliverable is defined in requirements documentation
Say, a customer wants a login screen design
Scope statement – Need to develop login screen
Requirements document
Need a login screen with the following fields – username, password, forgot username, forgot password, register new user, submit button
Color coding details – Red button, white background, fields should be black in color, links should be blue in color when normal, clickable link should turn into black color
Login screen behavior – Must be able to accept new username, existing username should throw error, user should be activated, password should meet criteria
Activation Behavior – Every valid registered user should be activated, activation link will expire in 3 hours
Say based on the above example if the customer gets a login screen designed with yellow submit button. IS this a quality deliverable?
As per PMP certified project managers who are considered top notch in industry, the answer is NO.
Now, lets revisit the term quality definition – Degree upto which project deliverable meets requirements. There is a simple color code requirement breach on button. So, this is not 100% quality product as per customer

Fix USER ospid terminating the instance due to error 16038

One of my customer did perform storage upgrade. After the upgrade some of their database systems did not startup normally. I got a call to investigate this issue. There are two different cases with two different databases
CASE #1:
1) Logged into sql prompt and did issue startup command to make sure database can be mounted and opened. Database did not startup as expected
2) did navigate to dump destination diag location. Checked alert.log file to see what is going on. I found the following error
ORA-16038: log 2 sequence# 1234 cannot be archived
ORA-19504: failed to create file “”
ORA-00312: online log 2 thread 1: ‘d:\DATABASE\SHEA\LOGFILES\LOG2A.ORA’
ORA-00312: online log 2 thread 1: ‘d:\DATABASE\SHEA\LOGFILES\LOG2B.ORA’
USER (ospid: 5454): terminating the instance due to error 16038
System state dump requested by (instance=1, osid=5454), summary=[abnormal instance termination].
System State dumped to trace file d:\DATABASE\SHEA\TRACE\diag\rdbms\SHEA\trace\SHEA_diag_3343.trc
Dumping diagnostic data in directory=[cdmp_20160503091224], requested by (instance=1, osid=5454), summary=[abnormal instance termination].
ARC0: Error 19504 Creating archive log file to ‘d:\DATABASE\SHEA\ARCHIVE\SHEA_T0001_S1234_R998978.ARC’
Instance terminated by USER, pid = 5454
3) This error shows that online redo log file has some corruption. Hence, I cleared the online redo log file group and the issue is fixed
alter database clear unarchived logfile group 2;
startup;

In case 1 online redo log is corrupt and could not create archived redo log
In case 2 archiving cannot happen owing to insufficient space in archival destination

CASE #2:
1) Logged into sqlprompt and startup the database. Database did not startup as expected
2) Navigated to dump destination and checked alert.log file. The file recorded the following error:
ARC0 started with pid=20, OS id=11552
ARC0: Archival started
ARC0: Becoming the ‘no FAL’ ARCH
ARC0: Becoming the ‘no SRL’ ARCH
LGWR: STARTING ARCH PROCESSES COMPLETE
ARCH: Error 19504 Creating archive log file to ‘b:\DATABASE\SHEA\ARCHIVE\SHEA_T0001_S1234_R77897868.ARC’
Errors in file b:\DATABASE\SHEA\TRACE\diag\rdbms\SHEA\trace\SHEA_ora_2234.trc
3) As a first step I navigate to archived redo log destination. When I checked the space it is found to be closer to 100% full.
4) Moved some archived redo logs from this location to temp location
5) Database did startup without any issue
I notified system administrator to add more space, move these files back onto this location. System administrator mentioned that more space can’t be added for another 2 days. Here is my recommendation for both the cases
CASE #1 – We need to perform a full backup atleast once to avoid missing archived redo log issue
CASE #2 – We need to perform full backup so that archival gap issue can be avoided during restore and recovery. In this case full backup is not the only fix. If not I asked him to safely maintain the copied archives , tag it properly and store it until more storage space is added or once full backup is done

Fix error ORA-27370 job slave failed to launch a job of type EXECUTABLE

Oracle database can work with OS utilities. One typical usage is scheduling of jobs using crontab in linux, windows job scheduler in windows. This ensures that job scheduling is controlled by OS , not at database level.
Now, comes the logical question. Why do I need so?
Say, if the DB is busy or has some issues that does cause problem with triggering job using oracle supplied dbms_Scheduler this implementation method comes handy. There are times wherein you wonder what is the real use of initiating an oracle dbms_scheduler job using OS utility when db itself is down?

Now, lets look at a typical issue that happened in one of our client sites. They had an executable created and scheduled via dbms_Scheduler, had a windows task scheduler job that will take care of triggering this executable run.
The client mentioned that backup did not happen as scheduled. They asked me to investigate further.
1) First I did navigate to user dump destination, looked at alert.log file and found the following error:
Errors in file D:\DATABASE\SHEA\diag\rdbms\shea\shea\trace\shea_j006_3412.trc:
ORA-12012: error on auto execute of job “SHEA”.”FULL_BACKUP”
ORA-27370: job slave failed to launch a job of type EXECUTABLE
ORA-27300: OS system dependent operation:accessing job scheduler service failed with status: 2
ORA-27301: OS failure message: The system cannot find the file specified.
ORA-27302: failure occurred at: jasec 9b
ORA-27303: additional information: The system cannot find the file specified
Errors in file
2) I did gather the job run details from dba_scheduler_job_run_Details view
spool job_run_Details.html
set markup html on
select * from dba_scheduler_job_run_details;
set markup html off
spool off
3) As a next step, I did look at the windows task scheduler. The job scheduled is in good shape. Action value is mapping to correct file location at OS level
4) Upon looking at job status at database level, the job is not broken
5) Now, I checked the services and found that Oraclescheduler service is stopped
Upon enquiry I found that they did install an application and stopped all oracle and realted services the day before. Once the maintenance is complete, they did start teh mandate services ORacleSHEA, OracleTNSListener but missed Oraclescheduler service. starting this fixed the

Fix RMAN-06059 error in single instance RAC environment

Have you ever wondered if there is an error that can compromise your job with your employer, this is none other than RMAN-06059 the archive log missing, compromises recover ability error
Lets consider the case of a normal single instance environment. When we try to perform backup plus archived redo log, perform backup of archived redo log alone issuing backup archivelog all, if you encounter the error RMAN-06059 expected archived log not found, lost of archived log compromises recover-ability that typically causes backup failure it is something to be noted.
At this point I always think about the way oracle corporation safeguard our job. Typically this error causes failure of backup that needs to be taken into consideration.

Now, let us see what causes this issue and how to fix it?
Archived redo logs form the heart and soul of performing safe, complete recovery of database. Note that missing archived redo logs will compromise data loss. The major reason behind this issue self-explanatory. RMAN is looking for an archived redo log file for backup, the file is missing
In real-time scenarios this can be result of initiating an RMAN backup on a user-managed backup environment. As part of user-managed backup, OS copy would have happened, file is removed physically. RMAN strategy would have been implemented. This entry is not updated in controlfile, causing the error
To fix it, run RMAN command : crosscheck archivelog all; Thsi updates the information in controlfile following which backup will be success
There are cases wherein the file is not part of recovery catalog, is not part of controlfile. To update this issue the command:
catalog start with ‘archivedloglocation’; Typically change in archival location that is not taken care of properly causes catalog to be out of sync. catalog command is an RMAN command that causes proper synchronization
Lets consider a RAC environment. It is typical in case of two node RAC to allocate two channels, perform backup using two channels. It is to be noted that parallelism should be set equivalent to or more than number of channels in RAC environment. IF not this error is caused
Log into RMAN, get details using command:
show all;
Change parallelism as needed. Say in case of three node rac with three channels, set this as follows:
show all;
configure device type disk parallelism 3;
Following this perform backup and this will be success

Oracle.DataAccess.Client.OracleException ORA-03135: connection lost contact fix

I got a call from one of my clients we support remotely. This is a customer hosting oracle database server as separate entity. Client applications do connect to the server in windows environment utilizing OLEDB. All websites have been working fine. All of a sudden the customer reported the following issue:
Oracle.DataAccess.Client.OracleException ORA-03135: connection lost contact
The error is self-explanatory as it says that the oracle client to server connectivity is lost. As a first step I tested to see if this issue has been happening on a continuous basis. It happened that this is an intermittent issue. Also, if the webpage is accessed from server there is no issue
Next step is to run fiddler capture while webpage is opened and I could not find real useful information from there

I checked sqlnet file setting expire_Time and this is not a big deal. Also, same setting was working fine all these days. Hence , this is not the cause of issue
I ran the trace from database server issuing
alter session set events ‘3135 trace name errorstack level 3’;
The trace files didn’t show something obvious. Also, no error that is of much significance is recorded in alert.log
Hence, it happened to me that this error is totally different and I did check the firewall settings. Now, comes the thief. Firewall was enabled by network admin by mistake causing issue with client server connectivity. They did fix the settings and this issue disappeared
