local node name olsnodes -l
activates logging olsnodes -g

Oracle Interfaces

display oifcfg getif
delete oicfg delig -global
set oicfg setif -global <interface name>/<subnet>:public
oicfg setif -global <interface name>/<subnet>:cluster_interconnect

Global Services Daemon Control

starting gsdctl start
stopping gsdctl stop
status gsdctl status

Cluster Configuration (clscfg is used during installation)

create a new configuration clscfg -install
upgrade or downgrade and existing configuration clscfg -upgrade
clscfg -downgrade
add or delete a node from the configuration clscfg -add
clscfg -delete
create a special single-node configuration for ASM clscfg -local
brief listing of terminology used in the other nodes clscfg -concepts
used for tracing clscfg -trace
help clscfg -h

Cluster Name Check

print cluster name cemulto -n

Note: in Oracle 9i the ulity was called “cemutls”

print the clusterware version cemulto -w

Note: in Oracle 9i the ulity was called “cemutls”

Node Scripts

Add Node addnode.sh

Note: seeย adding and deleting nodes

Delete Node deletenode.sh

Note:ย see adding and deleting nodes

En queues

displaying statistics SQL> column current_utilization heading current
SQL> column max_utilization heading max_usage
SQL> column initial_allocation heading initial
SQL> column resource_limit format a23;

SQL> select * from v$resource_limit;

Messaging (tickets)

ticket usage select local_nid local, remote_nid remote, tckt_avail avail, tckt_limit limit, snd_q_len send_queue, tckt_wait waiting from v$ges_traffic_controller;
dump ticket information SQL> oradebug setmypid
SQL> oradebug unlimit
SQL> oradebug lkdebug -t

Lighwork Rule and Fairness Threshold

downconvert select cr_requests, light_works, data_requests, fairness_down_converts from v$cr_block_server;

Note: lower the _fairness_threshold if the ratio goes above 40%, set to 0 if the instance is a query only instance.

Remastering

force dynamic remastering (DRM) ## Obtain the OBJECT_ID form the below table
SQL> select * from v$gcspfmaster_info;
## Determine who masters it
SQL> oradebug setmypid
SQL> oradebug lkdebug -a <OBJECT_ID>

## Now remaster the resource
SQL> oradebug setmypid
SQL> oradebug lkdebug -m pkey <OBJECT_ID>

GRD, SRVCTL, GSD and SRVCONFIG Tracing

Enable tracing ย $ export SRVM_TRACE=true
Disable tracing ย $ export SRVM_TRACE=””
