libgcc_s.so.1, ins_ctx.mk – Error while installing 11gR2 on OEL 5.3

leenus2b — Tue, 07 Sep 2010 05:48:34 +0000

While installing 11gR2 on Oracle Enterprize Linux 5 update 3, I faced below error during relink process

/lib/libgcc_s.so.1: undefined reference to `__stack_chk_fail@GLIBC_2.4′
collect2: ld returned 1 exit status
make: *** [ctxhx] Error 1

and

Exception String: Error in invoking target ‘install’ of makefile ‘/u10/app/SBLOSL/orsblosl/oracle/product/11.2.0/ctx/lib/ins_ctx.mk’

Upon investigating, I observed gcc version is 3.4.6, Where as oracle 11gR2 installer requires gcc version 4.1.x.

[orsblosl@rstnxovm9019 bin]$ ls -lart *gcc* *g++*

Hence I moved gcc and g++ in /usr/bin to backup directory and restored gcc.orig and g++.orig to gcc & g++ respectively.

Retry the relink lead to successful completion of the 11gR2 install.

Extracting Local database in siebel

leenus2b — Wed, 05 May 2010 07:27:32 +0000

1. Siebel Remote – Component Group needs to be enabled on the server.
This can be done by connecitng to server manager (srvrmgr) and executing

srvrmgr>list compgrp

If Siebel Remote is not enabled, need to execute the command

srvrmgr> enable component group Remote for server

Resatart Siebel server & verify Siebel Remote compgrp available on list compgrps command

2. Database Extract component (DbXtract) needs to be enabled on server

srvrmgr> list comp DbXtract

3. Generate New Database – Job needs to be executed

    Administration – Server Management > Jobs > New job
        > For Component/Job field select Generate New Database
        > For Requested Server field give
    In Job parameters applet Create New Value
        > Name column as SQL Any where database and value as sse_utf8.dbf
    Submit the job and ensure it was successful

4. Registering an employee as Siebel mobile webclient user

    Administration – Siebel Remote > Mobile Clients
    In Mobile Clients Applet
        > Mobile Client column
        > App Server Name as
        > UserID as user_available_as_employee

5. Executing DbXtract for the mobile user
    Administration – Server Management > Jobs > New job
        > For Component/Job field select Database Extract
        > For Requested Server field give
    In Job parameters applet Create New Value
        > Name column as Client Name and value as
        > Name column as Move Siebel Remote Cliet and value as True (For first time extract)
        > In Routing Model select value MOBILE CLIENT – EXTRACT ONLY
    Submit the job and ensure it was successful

Errors

Issue 1: After submitting Database Extract, the job was in Queued state for long time

issue can be identified as Siebel Remote compgrp / DbXtract comp was not enabled.

Issue 2: SBL-DBX-00038: No local database template found.

issue can be identified as not generated Database template

Issue 3: SBL-SMI-00077: Component error, see the trace file for more information

and in DbXtract_xxxxx.log contains
GenericLog GenericError 1 000000084b553068:0 2010-01-20 10:00:37 (smisched.cpp (894) err=1376333 sys=0) SBL-SMI-00077: Component error, see the trace file for more information

issue identified as not availability of Siebel mobile client users.

This can be confirmed by executing the command

select * from SIEBEL.S_NODE where NODE_TYPE_CD = ‘REMOTE’ and NAME=’SADMIN’ and EFF_END_DT is NULL;

which returns no rows (or) username for whom extract needs to be executed will not be in output

Using ‘at’ to schedule a job in Unix

leenus2b — Wed, 10 Mar 2010 18:44:55 +0000

Unix command ‘at’ can be used to schedule a task at specific time.To get into ‘at>’ command prompt use command ‘batch’.

[leenus@oracle ~]$ batch

at> at 5pm today

at> nohup tar -xzvf oracle.tgz > ~/nohup.out

at> mail -s “Scheduled task Completed” me@myhost.com << ~/nohup.out

ctrl+d to save the job.

To see the scheduled jobs we can give atq

To remove the scheduled job execute atrm -

Change Weblogic Listen Port: In Weblogic

leenus2b — Sat, 13 Feb 2010 03:09:57 +0000

Change Weblogic Listen Port:
In Weblogic server default Listen port is 7001. say, In DMZ servers open ports are between 10000-10999 in order to change Listen port (from back-end) we need to use WLST (weblogic scripting tool) utility if we need to change from back-end.

WLST tool can be invoken by wlst.sh from location $WEB_LOGIC_HOME /wlserver_10.3/common/bin

Idnetify the configured domain location , ( $WEB_LOGIC_HOME/domains/ )

wls:/offline> readDomain(‘/u10/app/HLDRET/orhldret/oracle/1013WCHome/WebLogic/wlserver_10.3/samples/domains/wl_server’);
wls:/offline/wl_server> cd(‘Server’)
wls:/offline/wl_server/Server> ls()

Killing hung database process..

leenus2b — Mon, 02 Nov 2009 04:15:09 +0000

Today We faced an issue, where an database process is kicking off again and again even we killed that in Database level.I identified that process was running as part of job in database (As the process corresponds to background process – j000 ) and followed the below procedure to kill that session.

I identified the job as ’203′ ,SID as ’80′ and username as ‘APEX_PUBLIC_USER’ etc., from dba_jobs_running using below query.

select jr.job,s.username,s.sid,s.lockwait,s.logon_time
from dba_jobs_running jr,v$session s
where jr.sid = s.sid
order by jr.job;

I used below query to broke the job before killing the session.

SQL> execute dbms_job.broken(’203′,TRUE);
begin dbms_job.broken
*
ORA-23421; job number 572400 is not a job in the job queue
ORA-06512: at “SYS.DBMS_SYS_ERROR” line 86
ORA-06512: at “SYS.DBMS_IJOB” line 514
ORA-06512: at “SYSDBMS_JOB”, line 240
ORA-06512: at line 1

I understood , I need to be the user who initiated the job to broke the job (or) have to use dbms_ijob package to broke the job as DBA.

BEGIN SYS.DBMS_IJOB.BROKEN(’203′,TRUE); END;
2 /

PL/SQL procedure successfully completed.

and used below command to kill the session and ensured no process is further kicked off..

alter system kill session ‘SID,SERIAL#’;

Generate Triggers in Siebel

leenus2b — Mon, 19 Oct 2009 16:25:43 +0000

General procedure for generating triggers is first removing triggers and then creating the triggers.
To acheive this, we will submit the job Generate Triggers twice with different parameters.

First for REMOVING triggers and next for CREATING triggers.

For Removing triggers we will give comp-specific parameter
REMOVE = TRUE
Trigger File Name = Trigger_remove.sql

For Creating triggers we will give comp-specific parameter
REMOVE = FALSE
Trigger File Name = Trigger_create.sql

Navigation:

Sitemap > Administration – Server management > Jobs

Create new job > Generate Triggers

From JOB PARAMETERS applet Select NEW and give the following component-specific parameters

EXEC                       ALL
MODE                     ALL
Privileged User       Table_owner (siebel_usr)
Privileged Pwd        Table_owner_pwd    (Siebel_usr_pwd)
Remove                  TRUE / False
Trigger File Name   Trigger_remove.sql / Trigger_create.sql (These sql files will be create in siebsrvr root directory and needs to executed manually if EXEC parameter was given as FALSE while executing jobs).

More info about triggers can be found at http://download.oracle.com/docs/cd/B40099_02/books/BPFWorkflow/BPFWorkflow_Admin_Policies4.html
