The pdlogls command cannot be used during offline operation to determine whether or not a system log file is in overwrite disabled status. The number of system log files in overwrite disabled status can be determined from messages that are output during restart processing:

Explanation

KFPS01262-I, KFPS01182-I, and KFPS01263-I indicate that system log files logfg04, logfg05, logfg06, and logfg07 are used during the restart. These are the overwrite disabled files, so the number of system log files in overwrite disabled status is 4:

Reference note

• If pd_mode_conf=AUTO or pd_mode_conf=MANUAL1 is specified, automatic restart processing was executed several times after the unit terminated abnormally and these messages were output each time. The set of messages that was output during the first abnormal termination are the ones that must be used.
• If pd_mode_conf=MANUAL2 is specified and restart processing is not performed (the pdstart command is not entered), the number of system log files used as input information during restart (the value derived as described in 18.17.1(2) Determine the number of system log files to be used as input information during restart) is the number of overwrite-disabled files.
• If the number of guaranteed valid generations of synchronization point dump files is 2 (if pd_spd_assurance_count=2 is specified), the number of overwrite-disabled files may increase further. Check by using the method shown below in (2) Determining the number of system log files in overwrite disabled status (number of valid generations = 2).

In (1) above, the system log files in overwrite disabled status that were in existence after the most recent synchronization point dump generation was validated were identified. If the number of synchronization point dump guaranteed valid generations is 2, the files in overwrite disabled status that were in existence up to the point where the previous synchronization point dump generation was validated must also be identified. There are two ways to identify these files:

• Using the synchronization point dump validation completion message (KFPS02183-I)
• Using the synchronization point dump validation skip message (KFPS02179-I)

(a) Using the synchronization point dump validation completion message (KFPS02183-I)

The files in overwrite disabled status can be identified using the KFPS02183-I message and the pdlogls command:

Explanation

1. This is the message regarding validation of the previous synchronization point dump generation. The indicated system log file is logfg03 (generation number 3).
2. This is the message regarding the most recent synchronization point dump generation. The indicated system log file is logfg04 (generation number 4).

It is clear from the first message that logfg03 is also in overwrite disabled status. Therefore, logfg03 through logfg07 are all in overwrite disabled status:

(b) Using the synchronization point dump validation skip message (KFPS02179-I)

The files in overwrite disabled status can be identified from the KFPS02179-I message:

Explanation

1. Look for the KFPS01221-I message indicating that logfg04, which is the system log input start point during the restart, was allocated as the current file.
2. Look for the KFPS02179-I message indicating that the validation skips count was set to 1 while logfg04 was being used as the current file.
3. If the KFPS02179-I message was output while logfg04's predecessor (logfg03) was used as the current system log file, look for the KFPS02179-I message indicating the validation skips count = 1, and identify the system log file that was being used as the current file when that message was output. Then determine the additional number of overwrite-disabled system log files from the following table:
   

   Condition		Output of KFPS02179-I message while the previous system log file generation was allocated as the current file
   		Output		Not output
   		Validation skips count 1	Validation skips count = 1
   Output of KFPS02179-I message while the input start system log file was allocated as the current file at the restart	Output	(Number of files existing up to the point where the message indicating skips count = 1 was output) + 1	2	2
   	Not output			1

Note

The number of files in overwrite disabled status determined in (1) plus the number of overwrite-disabled files determined above cannot exceed the total number of system log files in the corresponding HiRDB server. If the total number of system log files is exceeded, the total number of system log files in the corresponding HiRDB server must be used as the total number of overwrite-disabled system log files.

In this example, the KFPS02179-I message was output while logfg04, which is at the system log input start point during restart, was allocated as the current file. The KFPS02179-I message was not output while its predecessor, logfg03, was allocated as the current file. Therefore, logfg03 and logfg02 are identified as the system log files in overwrite disabled status, and a value of 2 is added to the result of (1).
