Checking the Shutdown Issue Caused by .proc.list File Corruption
1. Check the .proc.list File
This file is created at startup and deleted at shutdown.
[tibero@centro2 tbr2]$ ls -la total 0 drwxr-xr-x. 7 tibero dba 65 Apr 29 02:12 . drwxr-xr-x. 3 tibero dba 18 Mar 30 20:49 .. drwxr-xr-x. 2 tibero dba 23 Mar 30 20:49 audit drwxr-xr-x. 5 tibero dba 46 Mar 30 20:49 dump drwxr-xr-x. 7 tibero dba 91 Apr 29 02:07 log drwxr-xr-x. 3 tibero dba 85 Apr 29 02:12 out drwxr-xr-x. 2 tibero dba 237 Apr 29 02:10 path [tibero@centro2 tbr2]$ tbboot Change core dump dir to /home/tibero/tibero7/bin/prof. Listener port = 8629 Tibero 7 TmaxTibero Corporation Copyright (c) 2020-. All rights reserved. Tibero instance started up (NORMAL mode). [tibero@centro2 tbr2]$ ls -la total 4 drwxr-xr-x. 7 tibero dba 83 Apr 29 02:12 . drwxr-xr-x. 3 tibero dba 18 Mar 30 20:49 .. -rw-r--r--. 1 tibero dba 427 Apr 29 02:12 .proc.list drwxr-xr-x. 2 tibero dba 23 Mar 30 20:49 audit drwxr-xr-x. 5 tibero dba 46 Mar 30 20:49 dump drwxr-xr-x. 7 tibero dba 91 Apr 29 02:07 log drwxr-xr-x. 3 tibero dba 107 Apr 29 02:12 out drwxr-xr-x. 2 tibero dba 237 Apr 29 02:12 path
2. Check the contents of the .proc.list
Tibero 7 start at (2025-04-29 02:12:23) by 1000 shared memory: 140397178134528 size: 2147483648 shm_key: -1923932141 1 sem_key: 497944344 236 listener_pid: 3796 listener_port: 8629 listener_special_port: 8630 epa_pid: -1 3795 MONP 3797 MGWP 3798 FGWP0000 3799 FGWP0001 3800 FGWP0002 3801 FGWP0003 3802 FGWP0004 3803 PEWP0000 3804 PEWP0001 3805 PEWP0002 3806 PEWP0003 3807 PEWP0004 3808 PEWP0005 3809 AGNT 3810 DBWR 3811 RCWP
3. Reproduce the issue by intentional corruption
Tibero 7 start at (2025-04-29 02:12:23) by 1000 shared memory: 140397178134528 size: 2147483648 sh m_key: -1923932141 1 sem_key: 497944344 236 listener_pid: 3796 listener_port: 8629 listener_special_port: 8630 epa_pid: -1 3795 MONP 3797 MGWP
4. Unable to shut down
[tibero@centro2 tbr2]$ tbdown immediate /home/tibero/tibero7/instance/tbr2/.proc.list is invalid file. (line = 3, 6)
Cause
This occurs when the .proc.list file cannot be read due to ownership or permission changes, or abnormal file creation caused by user error.
Solutions
If the file still exists and cannot be restored, it must be deleted before proceeding.
1. Forcefully terminate the Tibero AGNT process
[tibero@centro2 tbr2]$ rm .proc.list [tibero@centro2 tbr2]$ ps -ef|grep tbsvr tibero 4352 1 3 02:20 pts/0 00:00:01 tbsvr -t NORMAL -SVR_SID tbr2 tibero 4354 4352 0 02:20 pts/0 00:00:00 tbsvr_MGWP -t NORMAL -SVR_SID tbr2 tibero 4355 4352 0 02:20 pts/0 00:00:00 tbsvr_FGWP000 -t NORMAL -SVR_SID tbr2 tibero 4356 4352 0 02:20 pts/0 00:00:00 tbsvr_FGWP001 -t NORMAL -SVR_SID tbr2 tibero 4357 4352 0 02:20 pts/0 00:00:00 tbsvr_FGWP002 -t NORMAL -SVR_SID tbr2 tibero 4358 4352 0 02:20 pts/0 00:00:00 tbsvr_FGWP003 -t NORMAL -SVR_SID tbr2 tibero 4359 4352 0 02:20 pts/0 00:00:00 tbsvr_FGWP004 -t NORMAL -SVR_SID tbr2 tibero 4360 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP000 -t NORMAL -SVR_SID tbr2 tibero 4361 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP001 -t NORMAL -SVR_SID tbr2 tibero 4362 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP002 -t NORMAL -SVR_SID tbr2 tibero 4363 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP003 -t NORMAL -SVR_SID tbr2 tibero 4364 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP004 -t NORMAL -SVR_SID tbr2 tibero 4365 4352 0 02:20 pts/0 00:00:00 tbsvr_PEWP005 -t NORMAL -SVR_SID tbr2 tibero 4366 4352 3 02:20 pts/0 00:00:01 tbsvr_AGNT -t NORMAL -SVR_SID tbr2 tibero 4367 4352 0 02:20 pts/0 00:00:00 tbsvr_DBWR -t NORMAL -SVR_SID tbr2 tibero 4368 4352 0 02:20 pts/0 00:00:00 tbsvr_RCWP -t NORMAL -SVR_SID tbr2 tibero 4602 2258 0 02:21 pts/0 00:00:00 grep --color=auto tbsvr [tibero@centro2 tbr2]$ kill -9 4366 [tibero@centro2 tbr2]$ ps -ef|grep tbsvr tibero 4604 2258 0 02:21 pts/0 00:00:00 grep --color=auto tbsvr [tibero@centro2 tbr2]$
2. Attempt to start
[tibero@centro2 tbr2]$ tbboot Change core dump dir to /home/tibero/tibero7/bin/prof. Listener port = 8629 Tibero 7 TmaxTibero Corporation Copyright (c) 2020-. All rights reserved. Tibero instance started up (NORMAL mode). [tibero@centro2 tbr2]$
3. If startup fails, remove shared memory and retry step 2
Use the tibero command
[tibero@centro2 tbr2]$ tbdown clean_shm
If the tibero command is not available, remove it directly from the OS
ipcs -m - check shmid ipcrm -m [shmid]
