Column |
Description |
Notes |
Glorefs |
Global references (database accesses).
Indicates the amount of work that is occurring on behalf of the current workload; although global references consume CPU time, they do not always require physical reads because of the buffer pool. |
|
RemGrefs * |
Remote global references (database accesses).
Indicates the number of global references that are generated on behalf of distributed cache cluster application servers. |
|
GRratio |
Ratio of global references to remote global references. |
|
PhyRds |
Physical reads from disk.
A high number of physical reads may indicate a performance problem; you can improve the performance by increasing the number of database (global) buffers. |
|
Rdratio |
Ratio of logical block reads to physical block reads, but zero if physical block reads is zero. |
|
Gloupds |
Global updates (sets or kills). |
|
RemGupds * |
Remote global updates. |
|
Rourefs |
Routine references (includes tag^routine). |
|
RemRrefs * |
Remote routine references. |
|
RouLaS |
Routine loads and saves (fetch from or save to disk).
A high number of routine loads/saves may indicate a performance problem; you can improve the performance by increasing the number of routine buffers. |
|
RemRLaS * |
Remote routine loads and saves. |
|
PhyWrs |
Physical writes to disk. |
|
WDQsz |
write daemon Queue size (in blocks). |
Not per second. |
WDtmpq |
Updated blocks in IRISTEMP. |
Not per second. |
WDphase |
Phase of the write daemon.
The most common phases are:
-
0: Idle (WD is not running)
-
5: WD is updating the Write Image Journal (WIJ) file.
-
7: WD is committing WIJ and Journal.
-
8: Databases are being updated.
|
Not per second. |
Wijwri |
Number of 256-KB blocks written to the WIJ.
This is non-zero when the WD is writing data to the WIJ. |
|
RouCMs |
Number of Routine Cache Misses. |
|
Jrnwrts |
Number of blocks written to journals. |
|
GblSz |
Number of seizes on the global resource; see Considering Seizes, ASeizes, and NSeizes. |
|
pGblNsz |
Percentage of NSeizes on the global resource; see Considering Seizes, ASeizes, and NSeizes. |
|
pGblAsz |
Percentage of ASeizes on the global resource; see Considering Seizes, ASeizes, and NSeizes. |
|
RouSz |
Number of seizes on the routine resource; see Considering Seizes, ASeizes, and NSeizes. |
|
pRouAsz |
Percentage of ASeizes on the routine resource; see Considering Seizes, ASeizes, and NSeizes. |
|
ObjSz |
Number of seizes on the object resource; see Considering Seizes, ASeizes, and NSeizes. |
|
pObjAsz |
Percentage of ASeizes on the object resource; see Considering Seizes, ASeizes, and NSeizes. |
|
ActECP * |
Number of active ECP connections. |
Not per second. |
Addblk * |
Number of blocks added to ECP Client’s cache. |
|
PrgBufL * |
Number of blocks purged from ECP Client’s cache due to global buffer shortage (on the ECP Client).
A high number may indicate a performance problem on the ECP client; you can improve performance by increasing the number of global buffers on the ECP Client. |
|
PrgSrvR * |
Number of blocks purged from ECP Client’s cache by ECP server. |
|
BytSnt * |
Number of bytes sent as an ECP Client. |
|
BytRcd * |
Number of bytes received as an ECP Client. |
|
WDPass |
WD cycle since startup. |
Not per second. |
IJUCnt |
Number of jobs that WD is waiting for to continue this cycle. |
Not per second. |
IJULock |
Indicates whether or not the IJULock flag is set .
If IJULock is set, all updates are locked out while the WD finalizes the write cycle. |
Not per second. |
PPGrefs |
The count of all process private global accesses. |
|
PPGupds |
The count of all process private global updates. |
