Consider the case in which a user explicitly switches context at the server - level using the execute as login statement 假設(shè)用戶(hù)使用execute as login語(yǔ)句在服務(wù)器級(jí)顯式切換上下文。
If the execute as statement has been used to switch context , system user returns the name of the impersonated context 如果已使用execute as語(yǔ)句進(jìn)行上下文切換,則system _ user將返回模擬的上下文的名稱(chēng)。
To allow for other workers to run , the current running worker has to relinquish control of the scheduler or switch context 若要允許其他工作線程運(yùn)行,當(dāng)前正在運(yùn)行的工作線程必須放棄對(duì)計(jì)劃程序或切換上下文的控制權(quán)。
First , the application must switch context to the user performing the encryption decryption by issuing the seckfmswitchtoidfile call 首先,因?yàn)閼?yīng)用程序必須通過(guò)調(diào)用seckfmswitchtoidfile將上下文切換到執(zhí)行加密/解密的用戶(hù)。
When called without an argument within a batch that has switched context by using execute as , suser sid returns the sid of the impersonated context 當(dāng)通過(guò)使用execute as切換上下文的批處理中無(wú)參數(shù)調(diào)用時(shí), suser _ sid將返回模擬上下文的sid 。
When called without an argument within a batch that has switched context by using execute as , suser sname returns the name of the impersonated context 當(dāng)通過(guò)使用execute as切換上下文的批中無(wú)參數(shù)調(diào)用suser _ sname時(shí),將返回模擬上下文的名稱(chēng)。
Switching context between users for example , switching from admin - user to another user , and then back multiple times has performance implications 在用戶(hù)間進(jìn)行多次上下文切換例如,從admin用戶(hù)切換到另一個(gè)用戶(hù),然后又切換回來(lái)會(huì)帶來(lái)性能隱患。
Because for each process created , not only is just the tss descriptor used for maintaining context - switch context being loaded , but an ldt descriptor is being loaded too 因?yàn)閷?duì)于所創(chuàng)建的每個(gè)進(jìn)程,都不僅要加載一個(gè)tss描述符用來(lái)維護(hù)上下文切換的內(nèi)容,另外還要加載一個(gè)ldt描述符。 )
