Recreate OCR/Voting Disk/SCLS Directories/Socket Files

OCR


 

If ocr has been deleted, then check the ocr mirror is ok and viceversa. It may be prudent to use the ocr mirror to create the ocr. If the ocr mirror and ocr have been deleted, then it may be restored from the ocr backups


 

Voting Disk


 

If there are multiple voting disk and one was accidentally deleted, then check if there are any backups of this voting disk. If there are no backups then we add one using the crsctl add votedisk command.


 

Socket files in /tmp/.oracle or /var/tmp/.oracle


 

If these files are deleted then stop the crs on that node and restart it agai. If the socket files for cssd is deleted then the crs may not come down then bounce the node.


 

SCLS directories


 

These are created by root.sh


 

If any of the above files cannot be restored then we will have to follow the following steps


 

Shutdown the crs stack on all nodes using command crsctl stop crs as root user

Backup the entire crs home

Execute <crs_home>/install/rootdelete.sh on all nodes

Execute <crs_home>/install/rootdeinstall.sh on primary node


 

The following command should return nothing

ps – e |grep –i 'ocs[s]d'

ps – e |grep –i 'cr[s]d.bin'

ps – e |grep –i 'ev[m]d.bin'

execute <crs_home>/root.sh on first node

after successful root.sh execution on first node execute root.sh on the rest of the nodes of the cluster


 

then

$/crs/install/racgons add_config node1:6251 node2:6251

For 11g as oracle execute the following code

$crs/install/onsconfig setif –global eth0/<ip>:cluster_interconnect eth1/<ip>:public

Add listener using netca. In case of error move listener .ora to another location and then run netca

Use appropriate srvctl commands to add asm, database, instance and services.


 

Execute cluvfy stage –post crsinst –n node1 node2

PRKH-1010 : Unable to communicate with CRS services

OS : AIX 5L Oracle 10g RAC Error message on one of the nodes PRKH - 1010 : Unable to communicate with CRS services I faced a typical issue.     The localconfig command has been used for a single instance RDBMS. There is absolutely no requirement to run localconfig on RAC system and it should never be used on RAC system as it will destroy the CRS configuration When the localconfig reset was run on only one system the following things happened. Ocr.loc was created at /etc/oracle/ora.loc. Cat /etc/oracle/ocr.loc is like : Ocrconfig_loc=<$ORACLE_HOME>/cdata/localhost/local.ocr Local_only=true   Cat /etc/inittab is like H1:35:respaw:/etc/init.d/init.evmd run >/dev/null 2>&1</dev/null H3:35:respawn:/etc/init.d/init.crsd run >/dev/null 2>&2 </dev/null H1:35:respawn:/etcc/init.d/init.dcssd run >/dev/null 2>&1 </dev/null<<< this one   As root Run the following scripts $ORA_CRS_HOME/install/rootdelete.sh $ORA_CRS_HOME/install/rootdeinstall...

vi Commands

What is vi? The default editor that comes with the UNIX operating system is called vi (visual editor). The UNIX vi editor is a full screen editor and has two modes of operation: Command mode commands which cause action to be taken on the file, and Insert mode in which entered text is inserted into the file. In the command mode, every character typed is a command that does something to the text file being edited; a character typed in the command mode may even cause the vi editor to enter the insert mode. In the insert mode, every character typed is added to the text in the file; pressing the (Escape) key turns off the Insert mode. While there are a number of vi commands, just a handful of these is usually sufficient for beginning vi users. To assist such users, this Web page contains a sampling of basic vi commands. The most basic and useful commands are marked with an asterisk (* or star) in the tables below. With practice, these commands should become automatic. NO...
