RAC & Failsafe :: How To Know About Listener.ora Parameter And The Endpoints File

Apr 2, 2010

information on this listener.ora parameter and the endpoints file? There is no reference in the docs (except for a sample listener.ora file in the RAC Installation Guide, no explanation).

Following a clusterware with gPNP installation, the listener.ora file has only IPC addresses, plus this parameter:

LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))))# line added by Agent
LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3))))# line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2))))# line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1))))# line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON# line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON# line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON# line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON# line added by Agent

The endpoints_listener.ora file specifies the fixed and VIP addresses of the public NIC:

LISTENER_GR7244=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.196.182.201)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=10.196.180.44)(PORT=1521)(IP=FIRST))))# line added by Agent

The listener named LISTENER is in fact listening on both its IPC address, and the addresses in the endpoints_listener.ora file:

[grid@gr7244 admin]$ lsnrctl status listener
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 02-APR-2010 04:52:02
Copyright (c) 1991, 2009, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))
STATUS of the LISTENER

[code]...

The scan listener on this node is listening on its IPC address, and its VIP:

[grid@gr7244 admin]$ lsnrctl status listener_scan3
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 02-APR-2010 04:46:15
Copyright (c) 1991, 2009, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3)))
STATUS of the LISTENER
------------------------
Alias LISTENER_SCAN3

[code]...

I did wonder if this parameter and file could be part of the mechanism whereby a listener discovers the DHCP assigned VIPs on which it has to listen?

Networking And Gateways :: Add SID In Listener.ora File To Reload Listener?

Jul 5, 2010

In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?

As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.

RAC & Failsafe :: Listener - VIP Doesn't Migrate From One Node To Another

Apr 17, 2012

I have the following problem on a 10.2.0.4 Oracle on AIX 1.6...

I have 2 RAC nodes as the node # 2 goes down, the VIP migrated correctly to the node # 1, but the listener # 1 do not see the change, and just resolve to the local ip.

The same does not apply in the reverse case, when it drops the node N 1, the listener attends to the fallen VIP node and migrated.The configuration is correct and identical in both nodes, according to the documentation, but I can not find a reasonable answer.

IP node # 1.
scm1or01 192.68.60.11
scm1or01-VIP 192.68.60.13

IP node # 2
scm1or02 192.168.60.12
scm1or01-VIP 192.168.60.14

Below I write as I detect the problem: when scm1or02 is down:

scm1or01:/cots/oracle/app/oracle/product/10.2.0/db_1/network/admin> lsnrctl status
LSNRCTL for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Production on 11-APR-2012 19:56:46
Copyright © 1991, 2007, Oracle. All rights reserved.
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
STATUS of the LISTENER
[code]...

Also the listener.ora in scm1or01 starts how LISTENER, but the crsstat says:

scm1or01:/cots/oracle/app/oracle/product/10.2.0/db_1/network/admin>crsstat listener_scm1oro1 ONLINE

I do not understand the reason, I've rebuilt the configuration of the listener, and netmgr netca tools, but the problem persists.

Networking And Gateways :: Setting QUEUESIZE Parameter In Listener.ora

Jun 27, 2012

I am planning to set QUEUESIZE parameter in listener.ora. In a non-rac database, we can set in %ORACLE_HOME%/network/admin/listener.ora

(ADDRESS = (PROTOCOL = TCP)(HOST = servername)(PORT = portnumber)(QUEUESIZE=n))

How to set the QUEUESIZE in a RAC Database with SCAN feature. listener.ora inside the grid home contains the following information

LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3)))) # line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2)))) # line added by Agent
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON # line added by Agent

and the endpoints_listener.ora contains the following (edited the host and ip details for maintaining confidentiality)

LISTENER_HOSTDB02=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostdb02vip)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=<ip of hostdb02>)(PORT=1521)(IP=FIRST)))) # line added by Agent

As per my understanding, QUEUESIZE parameter can be set inside the endpoints_listener.ora

RAC & Failsafe :: Create Shared File System Between Two Desktop PC?

May 14, 2013

We are setting RAC between two machines(Desktop PC connected wirth LAN ....have storage Local to them and no Shared storage..Only NFS).We have shared the mount point by NFS.We do not have any shared storage but we need to share the RAW files to setup the OCR and VOTING DISKS.

The problem is:

1. We need to keep the RAW devices for OCR and voting disk common to the machines (Desktop PC..both Linux OELU5). I am able to create the raw file systems but that is local to one machine. I am not able to understand how to share the raw devices between two machines.

2. Tried to use ISCSI utility but that did not work. (How_to_use_iSCSI_Targets_on_Linux)

Scenario : One Machine has 500 GB Storage. Second machine has 80 GB Storage. Made private and public networks(Used two Network cards in LAN). All are communicating.

Problem : Need to make the storage 300GB (Out of 500 GB) of Machine 1 as shared storage. How can we do that? (Do we need any virtual software...ex .. vmware for that?)

Application Express Listener :: Log Errors When Uploading File?

Sep 28, 2012

I get an ERR-7621 from Apex whenever I do anything in an application the tries to read a file. For example importing images, css files, themes, or applications. Even the data loader app will get the error if you choose to load a "csv" file. The following appears in my Apex Listener Log (version 2 early adopter). I am running 4.1.1 of Apex and also have another server running the same where the problem does not exist. Following is the log output whenever the load occurs:

Recreate Parameter File When Lost Or Corrupted?

Jul 1, 2010

recreate paramater file if you lost init.ora or spfile.ora

STEPS

SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file 'D:ORACLEORA92DATABASEINITGPT2.ORA'
How to resolve ORA-01078 with LRM-00109 error?

For resolving these error, you should need to replace init.ora or spfile if you have backup of same files. If you don't have backup then go to alert.log and copy all parameters in one file and save as "init.ora". Modify same init.ora with some parameters which need single quotation mark " ' " like background_dump_dest,controlfiles,db_name and "dispatchers ......)". Connect as sysdba in SQL*Plus and execute command "create spfile from pfile=" or startup pfile or startup.

Write Shell Script To Parse Parameter File

Mar 29, 2013

I'm working on trying to write a shell script to parse a parameter file, but at the same time I want to be able to overwrite the parameter file settings with other command line settings. For instance if my par file had export/import settings for the username, password, schema, etc;

I wanted to run the same export/import with those settings for a different schema. I want to be able to put the schema=<different_than_par_file> after the parfile=<parfile.par and have the parfile be read and applied for everything except the different schema.

Right now I'm storing the cmd line and parsing it again looking for other parameters besides the parfile.

Application Express Listener :: Using PL/SQL Procedure / Function In Resource Template (listener 1.1.3)

Feb 15, 2013

I'd like to call an existing function/procedure from a resource template. For example, I have a procedure called 'rest' with an out parameter of 'p_out' - how do I use this within a resource template?

At the moment I have defined the template as type 'PL/SQL Block' and with the 'GET' defined as:

begin
myschema.rest(:p_out);
end;

APEX_PUBLIC_USER has been granted 'all' on the procedure. The p_out is populated with a piece of text.

When I call this resource, I get a '500 Internal Error' returned. I've tried adding p_out as an X-APEX-FORWARD parameter, but nothing seems to work.

Query-based templates seem to work OK.

I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.

also,everytime when i give lsnrctl>show current_listener it is showing "listener"

i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.

RAC & Failsafe :: ORACLE Server Failover Parameters In Windows Server Machine.config File

Jan 17, 2012

working on setting up connection between a Windows 2008 server and a pair of Oracle 11g DBs in a RAC Cluster. One Database (let's say DatabaseA) is in one data center, and the other (DatabaseB) is an a secondary, backup database. The RAC Cluster is all set up, working fine, etc. However, I Need to set up the machine.config file on my Windows Server, to go only connect to DatabaseA, unless it fails, in which case, we want it to connect to DatabaseB. Think we could do this if the host app server was Linux/Unix, but it is windows, and I just don't have the background as to the parameters to set up in the machine.config file. They are similar, but different, and we want a very specific behavior (use DatabaseA, unless fails, then DatabaseB). Application is .NET 4.0 app.

Application Express Listener :: APEX Listener With APEX 3.0 On 11gR2?

Jun 29, 2012

We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.

When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.

The APEX listener appears to be more than just a Java PL/SQL gateway.

Is there a minimum version of APEX the APEX Listener supports?

RAC & Failsafe :: CRS Is Not Starting?

Oct 13, 2011

I am getting problem while starting the CRS. Below is the necessary details:

1) I am using oracle 11g R2 RAC, with 2 node named RAC1 and RAC2

2) I have 3 diskgroup named DATA, DATA1, DATA2

3) OCR and voting disks are stored on ASM diskgroup

On node RAC1, CRS is started and /etc/oracle/ocr.loc is having the below entry:

ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA1

On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:

ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA2

note the difference in "ocrmirrorconfig_loc". The difference was occured because I updated the OCR location on RAC1 when RAC2 was down.

Now I am trying to repair the RAC2 using below command. This command must be run as root user when HA service is started but CRS must be stopped.

ocrconfig -repair -replace +DAT2 -replacement +DATA1

but this showing error "PROT-21: Invalid parameter", because to run this command diskgroup must be mounted. But diskgroup cannot be mounted until the CRS start. SO this is a conflicting situation.

RAC & Failsafe :: DB Migration To New SAN?

Apr 30, 2012

We have to perform migration for our RAC database to new SAN that is at new data centre. Since OS is IBM AIX, we can take backup from mksysb for VG and and storage will migrate data from OLD SAN to NEW SAN.

But even we restore VG and SAN data but since our old SAN is emc and new SAN is hitachi, so disk path for all the asm disk group will be changed.

So is there will be any way to rename this disk path for disk group..
