insert into  tst_string values ('ANE4175I Starting Full VM restore of VMware Virtual Machine ''mfujiwara'' target node name=''VC1_DC1'', data mover node name=''VC1_DC1_DM3''  (SESSION: 3780)');
commit;
select * from tst_string;
MESSAGE

Hi Frank,
It looks like message can be seen as delimited lsit of sub-messages, where a number of different characters (perhaps ',' amd ':') may serve as delimiters. Each sub-message may or consist (entirely or in part) of something you want to display.Yes. In my first case where is "ANR0166I" I want get the characteres before "," (e.g "OSOGBO," I want get "OSOGBO") excluding "(SESSION: 1506, PROCESS: 2)"
Would a user-define PL/SQL function be okay for you?Yes.. no problem.
I'm not good with shell script, but will try show what I want using SHELL commands:
See this example:
### I create a file named "tst_string"
$ vi tst_string
ANR0166I Inventory file expiration finished processing for node OSOGBO, filespace OSOGBO\SystemState\NULL\System State\SystemState, copygroup BACKUP and object type GROUP BASE with processing statistics: examined 43, deleted 43, retrying 0, and failed 0. (SESSION: 1506, PROCESS: 2)
## So I used a function sed to get my desired values. The command bellow is poor, but My point is the result.
$ cat tst_string | sed 's/ANR0166I.*node //g' | sed 's/, filespace//g' | sed 's/, copygroup BACKUP and object type GROUP BASE with processing statistics: //g' | sed 's/. (SESSION.*//g' | sed 's/, deleted//g' | sed 's/, retrying//g' | sed 's/, and failed//g'
OSOGBO OSOGBO\SystemState\NULL\System State\SystemState 43 43 0 0The result was:
NODE     FILESPACE                              Examined     Deleted     Retrying        Failed      
OSOGBO      OSOGBO\SystemState\NULL\System State\SystemState     43           43      0           0I will go check the links wich you mentioned.
Thanks
