1、SAP GUI终端用户登录提示："rabax during sapgui logon"；检查/usr/sap/DEV/DVEBMGS00/work/dev_disp 日志：
*** WARNING => DpHdlDeadWp: wp_adm slot for W22 has no pid [dpxxwp.c 1362]
仍无法定位问题原因。
检查dev_rfc.trc发现
logsegment full
的字样。
2、检查数据库日志：/sybase/DEV/ASE-16_0/install/DEV.log中提示大量：
Can't allocate space for object 'syslogs' in database 'DEV' because 'logsegment' segment is full
3、临时解决方案，sapsa登录Sybase isql：>dump transaction DEV with no_log >go
4、调整DEV数据库的logsegment大小：
A.扩容数据库设备，增加15360MB；
>disk resize name="DEV_log_001", size="15360M"
>go
B.调整数据库服务器为单用户模式；
>use master
>go
>sp_dboption master, "single user",true
>go
>use DEV
>use go
>checkpoint
>go
C.执行sp_extendsegment
>alter database DEV on DEV_log_001=15360
>go
>sp_extendsegment logsegment DEV DEV_log_001
>go
D.查看当前log_size,可使用如下SQL语句；
https://benohead.com/sybase-size-of-data-and-log-segments-for-all-databases/
select db_name(d.dbid) as db_name,
ceiling(sum(case when u.segmap != 4 then u.size/1048576.*@@maxpagesize end )) as data_size,
ceiling(sum(case when u.segmap != 4 then size - curunreservedpgs(u.dbid, u.lstart, u.unreservedpgs) end)/1048576.*@@maxpagesize) as data_used,
ceiling(100 * (1 - 1.0 * sum(case when u.segmap != 4 then curunreservedpgs(u.dbid, u.lstart, u.unreservedpgs) end) / sum(case when u.segmap != 4 then u.size end))) as data_used_pct,
ceiling(sum(case when u.segmap = 4 then u.size/1048576.*@@maxpagesize end)) as log_size,
ceiling(sum(case when u.segmap = 4 then u.size/1048576.*@@maxpagesize end) - lct_admin("logsegment_freepages",d.dbid)/1048576.*@@maxpagesize) as log_used,
ceiling(100 * (1 - 1.0 * lct_admin("logsegment_freepages",d.dbid) / sum(case when u.segmap in (4, 7) then u.size end))) as log_used_pct
from master..sysdatabases d, master..sysusages u
where u.dbid = d.dbid and d.status != 256
group by d.dbid
order by db_name(d.dbid)
