【文章內(nèi)容簡(jiǎn)介】 改變對(duì)象 ?Odmdelete 刪除對(duì)象 2020/11/4 Dalian University of Technology 20 修改屬性值 odmget quniquetype=tape/scsi/scsd and attribute=block_size PdAt file vi file Modify deflt to 512 odmdelete o PdAt quniquetype=tape/scsi/scsd and attribute=block_size PdAt: uniquetype = tape/scsi/scsd attribute = block_size deflt = “512 values = 02147483648,1 width = type = R generic = DU rep = nr nls_index = 6 odmadd file 2020/11/4 Dalian University of Technology 21 修改 ODM屬性值注釋 ?Odmget命令在這個(gè)例子中會(huì)從 PdAt中選擇所有的記錄，選擇條件： uniquetype=tape/scsi/scsd, attribute=block_size。在此情況下，只有一個(gè)記錄是吻合的，這些信息被重定向到一個(gè)文件，可以用編輯器來(lái)修改。在這個(gè)例子中，屬性 block_size的默認(rèn)值改為 512. ?注意：在新值 512被加到 ODM中乊前，舊對(duì)象（它的block_size已被設(shè)置為空值）必須被刪除，否則你最終將會(huì)在數(shù)據(jù)庫(kù)中有兩個(gè)對(duì)象描述相同的屬性（ otherwise you would end up with two objects describing the same attribute in the database）第一個(gè)被發(fā)現(xiàn)的對(duì)象將被使用，結(jié)果可能會(huì)非?；靵y。這就是為什么要先刪除條目再增加替換的記錄。最后的操作是添加文件到 ODM. 2020/11/4 Dalian University of Technology 22 用 odmchange修改屬性值 odmget quniquetype=tape/scsi/scsd and attribute=block_size PdAt file vi file PdAt: uniquetype = tape/scsi/scsd attribute = block_size deflt = “512 values = 02147483648,1 width = type = R generic = DU rep = nr nls_index = 6 Modify deflt to 512 odmchange o PdAt quniquetype=tape/scsi/scsd and attribute=block_size file 2020/11/4 Dalian University of Technology 23 查詢(xún)數(shù)據(jù)庫(kù)條目 ?測(cè)試條件 = 等于 != 不等于 大于 = 大于或等于 小于 = 小于或等于 like 模糊查詢(xún) 2020/11/4 Dalian University of Technology 24 查詢(xún)數(shù)據(jù)庫(kù)條目 ?丌同的測(cè)試條件可以用布爾運(yùn)算符 連接 and, or ?通配符 * 匹配任意 多個(gè)任意字符 ? 匹配任意一個(gè) 字符 ?例子 ? lpp_name like bosext1.* //匹配 lpp_name的屬性以 bosext1. 開(kāi)頭的 ? uniquetype=tape/scsi/scsd and attribute=block_size 2020/11/4 Dalian University of Technology 25 軟件重要產(chǎn)品數(shù)據(jù) lpp: name = “ size = 0 state = 5 ver = 6 rel = 1 mod =0 fix = 0 description = Front End Printer Support“ lpp_id = 38 product: lpp_name = “ p_id = 5765C3403“ state = 5 ver = 6 rel = 1 mod =0 fix = 0 ptf = “ prereq = *coreq “ description = “ supersedes = inventory: lpp_id = 38 private = 0 file_type = 0 format = 1 loc0 = /etc/qconfig“ loc1 = “ loc2 = “ size = 0 checksum = 0 history: lpp_id = 38 ver = 6 rel = 1 mod = 0 fix = 0 ptf = “ state = 1 time = 1187714064 ment = 2020/11/4 Dalian University of Technology 26 軟件重要產(chǎn)品數(shù)據(jù)的內(nèi)容 ?當(dāng)在 AIX系統(tǒng)中安裝一個(gè)產(chǎn)品戒更新時(shí) ， installp命令用ODM維護(hù)軟件重要產(chǎn)品數(shù)據(jù)庫(kù)（ SWVPD） ?軟件產(chǎn)品的名稱(chēng) ?軟件產(chǎn)品的版本號(hào)、發(fā)行號(hào)、修定號(hào)、補(bǔ)丁號(hào)（ ， ) ?以前打過(guò)的補(bǔ)丁，已經(jīng)安裝在系統(tǒng)上 ?軟件產(chǎn)品的狀態(tài) Available (state = 1) Applying (state = 2) Applied (state = 3) Committing (state = 4) Committed (state = 5) Rejecting (state = 6) Broken (state = 7) $installp –C //清除 ing狀態(tài)的軟件 $
