Hi,

We had an issue where our  SAP ECC system was crashing due to LWP value reaching more than 56K.
The Unix team found from dtrace logs that the segkpsize had reached limit and hence the system was crashing. As a solution, the unix team    increased the value of segkpsize : 524288 and now the lwp upper limit is around 128K. The segkpsize was earlier set to segkpsize: 262144.
4. However now that we are tracking the lwps count on the CI-DB server, we are observing that between 12:00 and 20:30, the value of lwp's peaks upto 70K  and we are concerned that it would kep increasing.
5. On checking with  ps -leafo nlwp,user,pid,args | sort -nk 1 command we are seeing around 175 to 200 oracle processes running with 258 lwp units each.

We have some Queries and concerns to investigate incase this issue reoccurs or the number of lwp increases.

1. Is there any normal acceptable value for lwp count in heavly used SAP system. Our load at the moment is

prstat 2 5 | grep lwp

Total: 698 processes, 54951 lwps, load averages: 21.83, 25.52, 24.82

Total: 698 processes, 54951 lwps, load averages: 21.83, 25.50, 24.82

Total: 698 processes, 54951 lwps, load averages: 21.82, 25.47, 24.81

Total: 698 processes, 54951 lwps, load averages: 21.87, 25.45, 24.80

Total: 698 processes, 54963 lwps, load averages: 21.94, 25.44, 24.80

2. what are the factors in SAP that control the lwps count.
3. We can identify the process running with high number of lwp is there any way to relate them to SAP process and reduce the lwps consumption.
4. is this a Solaris 10 limitation.

Any help would be appreciated.

Thanks

Hi All,

I want to shrink my Oracle DB in production environment, because it was occupied 92% of storage allocated.

I have checked mos of the tablespaces are also reached to 98%, I have some old spool data around 170 GB showing in LOB segment, so If I delete that data, how can I retain my free space?.

Or any other way to shrink the DB inorder to increase the performance.

Kindly help me to resolve this problem.

Hi,

We are moving from a oracle 10g, Solaris 10 environment to Oracle 11, Solaris 11 environment. The Oracle 11 database will reside in a ZFS filesystem.

I am looking for inputs on the configuration of the oracle redo logs in a ZFS pool

I read an Oracle whitepaper where the recommendation is as follows

ZFS-POOL1: All datafiles; Recordsize=8k, logbias=throughput;compression off

ZFS-POOL2: Redologs; Recordsize:128K or 1M,logbias=latency;compression off

ZFS-POOL3: Archived logs;Recordsize:128K; logbias: througput

Can we configure the redologs and the datafiles in the same pool?

Can we configure the redologs with 'logbias=throughput' instead of 'logbias=latency'?

SAP note 1343733 does state that the redo logs should be in a different pool but is there anyone who has configured the redo logs in the same pool as the datafiles?

Regards,

Aj

Hi Colleagues,

I have a requirement to implement a High Availability for ECC on Solaris server. We are running ECC on HANA with distributed installation (ECC on Solaris, HANA on Linux). The High Availability on the HANA side is already taken care of. I would like to know the HA configuration option for the ECC. We will be installing Primary application server (CI) , ASCS, ERS and  3 Additional Application servers (Dialog instances) All of these will be installed with Virtual IPs on Solaris.I am interested in knowing about HA configuration options. As of now, Our plan is to install ASCS on node A and ERS on node B of a cluster with fail over configured for the SPOF components.We also want to configure failover for the CI and Dialog Instance, as we do not want any user sessions (work processes) to be cancelled when any of these instances fail. For this, Is it possible for me to configure Virtual IP based failover of the CI and Diolog Instances from the Production to Quality so that when the Prod failsover to QA, the QA will shutdown and be used for Prod? I would like to know how this kind of configuration works. How can QA be configured such that it can be used for QA as well as a passive node for Prod failover? I would like to know the high-level of how this process happens and how the filesystems and networks are configured for this to happen. Could you please shed some light on this topic.

Thanks!

hi experts,

we have a need that we want to alllow multiple login in sap to more than 100 users who share their logins, as we add the users to

I have an issue where I know that SAP lost connection to the Oracle Database at a certain time yesterday, and then the SAP system was restarted in the AM without issue. The problem I  have is that I can not find what the issue is as to why the Database lost connection to SAP ? Where would I go to find this information. I have searched the System log SM21 and it stops at the time when the database lost connectivity and starts back up again at the time when the SAP came back on line, the last messages indicate Oracle errors that are not found in T100 which I am not familiar with.

Messages like this...I have no idea what this means.

all of function GwRead failed, RC: -006

Database error 1116 at SEL access to table T100

facility=ORA#; arguments: [45]#ORA-01110: Message 1110 not

found; product=RDBMS; facility=ORA#; arguments: [45]

. ST03N show's me nothing about an Oracle DB error.

Any Ideas where I can find an error message that would help determine root cause. ?

Dear Colleague,

Can you please guide me through some SAP notes on how to set up the oracle user on 12c in order for our dba to do the administration tasks?

As we are confused in the SWPM installation there is an option where you can tick orasid .

But as i have understood since oracle 12c oracle user is the one used for administration.

And now there is a confusion.

I have explained that the oracle user should take care of the administration but few steps need to be done on oracle level for that.

Can you please advise?

Many thanks

Dear Experts,

please kindly help me, I need your strong support very much !!

Currently, I am working on a unicode conversion. After deleting the source system, it became necessary to restore it.

I had taken a full consistent backup of the database with BRBACKUP, just before the export. On wednesday I have

restored this backup without ANY problems !!!

On thursday (yesterday), it became necessary to restore the system once again, due to a bug in SMIGR_CREATE_DDL

(the import was failing). So I went on to restore the very same backup, which restored successfully on wednesday !!!

So, if it restored once, it means, that the backup is 100% valid and usable!

But yesterday, the restore failed, then I tried it again and the second time it failed as well !!! Exactly at the same percentage:

I have run dbv against sysaux.data1 - it came back fine, stating Total Pages Failing : 0 for everything!

I have asked our storage admin to have a look at it - he didn't find nothing !!! We have executed this command:

LANG=C cp /datadomain/backup_oracle/sap_backup/<SID>/beratvvl/sysaux.data1 /oracle/<SID>/sapdata4/sysaux_1/sysaux.data1

On the OS prompt and it finished successfully (the return code was 0) !!!

So, all this is a VERY BIG mystery, ESPECIALLY bearing in mind, that this backup restored once successfully !!

I've been reviewing threads with the similar problem, but nothing was relating to my case or giving some meaningful suggestions.

Please kindly advise on how to solve this! Many thanks in advance!
