PROT-1 PROC-26 ORA-12536: TNS:-Operation would block errors During GI root.sh

Hi,

Sometimes You can get ” PROT-1 PROC-26 ORA-12536: TNS:-Operation would block errors ” During GI root.sh .

 

Details of error are as follows.

Grid Infrastructure root.sh fails on node1,

Disk Group DATA created successfully.

PROT-1: Failed to initialize ocrconfig
PROC-26: Error while accessing the physical storage
ORA-12536: TNS:-Operation would block

2020/05/04 11:34:42 CLSRSC-157: Failed to create Oracle Cluster Registry configuration
2020/05/04 11:34:42 CLSRSC-259: Oracle Clusterware Repository configuration failed

 

 

This error is related with Insufficient ulimit setting for root user.

For linux:

# ulimit -a
....
open files (-n) 256
....
max user processes (-u) 128

 

For Aix:

the maxuproc ( Maximum number of PROCESSES ) was set too low

lsattr -El sys0 | grep maxuproc
maxuproc 128 Maximum number of PROCESSES allowed per user True

 

To solve this error, increase it to 16384

lsattr -El sys0 | grep maxuproc

maxuproc 16384 Maximum number of PROCESSES allowed per user True

 

After change the ulimit to the recommended value in orachk, re-run of root.sh will be successful.
