It should be noted that the goal systems can be including but not limited to linux system, Windows systems, XP systemsSystem, Ios systems etc..Below so that linux system is goal systems as an example, the application is illustrated.
It should be noted that the system software of the goal systems can include goal systems inner nuclear layerSoftware, the file system of goal systems and bibliographic structure and database；In order in the step S13 in goal systemsUpgrade-system environment in the security upgraded to system software and reduce the risk to system software upgrading as much as possible,Using escalation policy upward under being carried out first to goal systems, i.e., such as kernel first in upgrade-system environment to goal systemsThe system softwares such as layer, file system and bibliographic structure are upgraded, while soft to system in upgrade-system environment in order to reduceThe upgrading risk of part, the system software of the goal systems need to obtain the soft of minimum underlying system software more by taking turns test onePart bag set so that the system software with minimum software kit set can be escalated into successfully in upgrade-system environmentWork(.The nonsystematic software of the goal systems can include but is not limited between application software, system software and application softwareInterface software etc., the wherein application software can be word processor (such as word, WPS), information management software, auxiliaryDesign software (such as CAD) and real-time control software etc..
Further, in order to ensure the complete upgrading to goal systems and upgrade successfully, in the step S13 describedBefore upgrading in upgrade-system environment to the system software, in addition to：Judge root partition in the goal systemsWhether idle storage space meets default system upgrade demand space, if if meeting, to the number in the goal systemsUnloading is carried out according to storehouse.If for example, the default system upgrade demand space for completing the complete upgrading needs to goal systems is1.3GB, if wherein the idle storage space of the root partition of the goal systems (such as linux system) is 1.8GB, it is seen that describedThe idle storage space of the root partition of goal systems meets system upgrade demand space, and in order to ensure having in goal systemsThe reservation of some data of importance, it is to avoid lost during system upgrade, thus before read apparatus is upgraded andIt is me to meet system upgrade demand space, and unloading is carried out to the database in goal systems, is realized to the data in goal systemsThe data retained are needed to carry out unloading in storehouse, so that sequential reduction is into the database.
Further, before the step S13 in the goal systems database carry out unloading, including：It is based onDefault data storage list, by the corresponding data conversion storage of database in the goal systems into goal-selling path.NeedIt is noted that the default data storage list can be when upgrading tool is developed, previously according to targetRunning situation statistics carries out management and control and the file and path list that retain the need for obtaining, can also be normal for goal systemsThe index list of essential file and catalogue during operation.According to the default data storage list, by the target systemThe corresponding data conversion storage of database in system realizes the file and mesh to needing to retain into specified goal-selling pathRecord carries out preset in advance reservation, it is to avoid during upgrading to goal systems, and the data for needing reservation are depositedThe generation of the loss problem of data in the corresponding database of storage list.Here, the form of expression of data conversion storage can be supportedThe migration of database in Relational DBMS (such as MySQL and sqlite), can also be support dynamic textThe migration of database in part system (such as Zettabyte FileSystem and zpool).
Further, before the step S13 based on default data storage list, by the number in the goal systemsAccording to the corresponding data conversion storage in storehouse into goal-selling path, including：
According to the type of the database, corresponding database instruction is determined；
It is based on the default data storage list and database instruction, the database in the goal systems is correspondingData conversion storage is into goal-selling path.
It should be noted that the type of the database can include but is not limited to be network database (NetworkDatabase), relational database (Relational Database), tree shaped data storehouse (HierarchicalDatabase), faceTo object database (Object-oriented Database) etc., wherein, the relational database can for Oracle, DB2,Sybase, MS SQL Server, Informax and MySQL etc..Different type of database, when being operated to databaseThe different database instruction of correspondence.
In the embodiment of the application one, before the step S13, in the idle storage for the root partition for judging to obtain goal systemsSpace is met after the default system upgrade demand space, according to the type of the database, determines that corresponding database refers toData in database are carried out unloading, i.e., according to database instruction, by default data by order according to corresponding database instructionThe corresponding data conversion storage of the corresponding database in goal systems of list is stored into specified goal-selling path.For example,If the type of the database is mysql databases, it is determined that corresponding database instruction instructs for mysqldump, by thisData storage list correspondence corresponding in database data exports and are transferred to specify described and preset by mysqldump instructionsIn destination path, realize to the file retained the need in goal systems and the reservation in the path of catalogue, it is follow-up right to be also convenient forCorresponding data are reduced in database, it is to avoid need the data storage list retained corresponding data in database to existGoal systems carries out escalation process loss, it is ensured that the security of data.
Because the deployment way in goal systems is varied, to improve the service behaviour of goal systems, by goal systemsIt is deployed on the extremely limited DOM cards in space, and the requirement due to aol server to its own system environment is harsh, and it is necessaryEnsure the ability of the upgraded in offline of the goal systems, therefore when upgrading to goal systems, need to be according to the root of goal systems pointThe idle storage space in area is judged, to cause the idle storage space for different root partition, carries out different spacesOperation is handled, to ensure that there is goal systems enough spaces to be upgraded.
In the embodiment of the application one, the free time for judging the root partition in the goal systems before the step S13 depositsWhether storage space is met after default system upgrade demand space, in addition to：If it is not satisfied, then to being stored in the root partitionData carry out unloading, until the idle storage space of the root partition meets the default system upgrade demand space.ExampleSuch as, if the default system upgrade demand space for completing the complete upgrading needs to goal systems is 1.3GB, if wherein the meshThe idle storage space of the root partition of mark system (such as linux system) is 1.1GB, it is seen that the root partition of the goal systemsIdle storage space is unsatisfactory for system upgrade demand space, in order to ensure have enough idle storage spaces to enter goal systemsRow upgrading, therefore need the data stored in root partition carrying out unloading, to vacate the space of root partition, until the free time of root partitionMemory space disclosure satisfy that the default system upgrade demand space, and then be able to ensure that the root partition of goal systems has footEnough idle storage spaces carry out system upgrade.
Further, in order to avoid the goal systems root partition idle storage space threshold value (that is, institute in root partitionSome data are all carried out in unloading or root partition without any data of storage) still it is unsatisfactory for carrying out upgrading needs to goal systemsDefault system upgrade demand space, then unloading is carried out to the data that are stored in the root partition before the step S13Afterwards, in addition to：If the idle storage space threshold value of the root partition is unsatisfactory for the default system upgrade demand space,Root partition described in prompting user is unsatisfactory for the default system upgrade demand space.If for example, completing to the complete of goal systemsThe default system upgrade demand space that whole upgrading needs is 1.3GB, if wherein the goal systems (such as linux system)(that is, all data are all carried out in unloading or root partition without storage times the idle storage space threshold value of root partition in root partitionWhat data) be 1.2GB, then need to point out the idle storage space threshold value 1.2GB of the root partition of user's goal systems to be unsatisfactory forThe default system upgrade demand space is 1.3GB, to make user solve to enter the goal systems by way of artificially handlingThe problem of default system upgrade demand space required for row upgrading is not enough.Further, if to being stored in the root partitionData carry out unloading after, it is empty that the idle storage space threshold value of the root partition is unsatisfactory for the default system upgrade demandBetween, then need the data convert stored in the root partition by unloading into root partition, it is to avoid the data stored in root partition are lostLose, the idle storage space threshold value that user's root partition is reresented afterwards is unsatisfactory for default system upgrade demand space.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgradingSuccess, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Deletion is embedded in instituteState the upgrade-system environment in goal systems.In order to reduce the risk upgraded to goal systems, therefore in target systemEmbedded upgrade-system environment in system, the program upgraded for running to goal systems is simultaneously soft to the system in goal systemsPart is upgraded, and to avoid influencing each other between the program and system software for upgrading, is upgraded to goal systemsAfter success, the upgrade-system environment that need to be embedded in the goal systems is deleted, to save the storage resource of goal systems.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgradingSuccess, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on described defaultData storage list and the goal systems that is transferred under the goal-selling path in the corresponding data of database, it is rightThe database is recovered.If here, data storage list file essential when normally being run for goal systemsWith the index list of catalogue, for example, the recovery to living document system, especially to the corresponding storage pool of living document systemRecover, because living document system is during being upgraded, can cause to be built in the corresponding storage pool of living document systemVertical file system failure, therefore need according to living document system dependent instruction, data storage list correspondence is transferred to defaultData recovery in destination path is realized to protecting the need in goal systems into the corresponding storage pool of living document systemThe file stayed and the reservation in the path of catalogue, based on data storage list and can correspond to the goal-selling path of unloading rapidlyFind the data of unloading, additionally it is possible to accurately and quickly by the data recovery of unloading into goal systems.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgradingSuccess, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on described defaultData storage list, database instruction and the goal systems that is transferred under the goal-selling path in database pairThe data answered, recover to the database.Here, if desired recovering to the mysql databases in goal systems, thenIt is pre- based on this when the data in the database are recovered, it is necessary to call the corresponding database instruction of mysql databasesIf data storage list, will be in the goal systems that be transferred under goal-selling path before carrying out system upgrade shouldThe corresponding data of mysql databases, are imported and to the mysql databases, to realize the mysql databases of goal systemsIn the need for the data that retain recovered.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgradingSuccess, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on the dataList is stored, data scrubbing is carried out to its own system environment of the goal systems.Produced to remove in escalation processRaw file abnormal residual, will be described based on the corresponding file of the data storage list for needing to retain and the path of catalogueIt is all in addition to the path of the corresponding file of the data storage list and catalogue in its own system environment of goal systemsData dump, and then the abnormal residual of the uncontrolled file in its own system environment of goal systems will be entered in escalation processRow cleaning, it is ensured that the controllability and security of its own system environment of goal systems, and save the storage resource of goal systems.
In summary, in a kind of method for upgrading system that the application is provided, during in order to upgrade to goal systems, it is considered toTo goal systems its own system environment the bottom software and file system of the goal systems of itself are upgraded during,Influenceed by its own system environment, in some instances it may even be possible to the machine of delaying can be caused, therefore before upgrading to the goal systems, in the meshAn embedded upgrade-system environment in mark system, so that the ROMPaq needed for upgrade-system can be in the upgrade-system environmentRun, its own system environment separation of upgrade-system environment and goal systems is opened so that the upgrading of whole escalation processProgram is run in the case where departing from its own system environment, and then is no longer influenceed by its own system environment, can be completely free of literInteractional limitation between upgrade-system environment and its own system environment where level program operation, is reduced to target systemThe risk united during being upgraded.
Then above-described embodiment, in order to ensure the integrality upgraded to goal systems, before being upgraded, is also neededJudge whether the idle storage space of the root partition of goal systems meets default system upgrade demand space, if if meeting,The database retained needing system to need carries out unloading, and default data storage list is corresponding in goal systemsThe corresponding data conversion storage of database into specified goal-selling path, if if being unsatisfactory for, by what is stored in root partitionData carry out unloading, until the idle storage space of root partition meets the default system upgrade demand space of upgrading needs, ifData conversion storage in root partition is finished, default system upgrade demand space is still unsatisfactory for, then by all numbers of unloadingAccording to being restored in root partition, and the default system upgrade demand for pointing out user's root partition to meet system upgrade demand is emptyBetween.
Then above-described embodiment of the application, the corresponding data in goal systems is stored in the corresponding database of listData are carried out after unloading, run ROMPaq in the upgrade-system environment, to the system software in goal systems (for exampleKernel software in inner nuclear layer, file system and structured file etc.) upgraded, after the completion of upgrading to system software,By changing after boot manager (grub configurations), the goal systems is restarted, the grub configurations are by escalation process from describedSwitched in upgrade-system environment in its own system environment, to realize the switching to upgrade-system environment and its own system environment,And nonsystematic software (such as application software package) is upgraded in its own system environment, and by data storage listThe corresponding data convert being transferred under the goal-selling path specified will remove data storage list into corresponding databaseOutside all data carry out cleaning deletion, while the embedded upgrade-system environment is deleted, to save goal systemsStorage resource；By using embedded upgrade-system environment and the environment of its own system environment separation formula respectively to goal systemsSystem software and nonsystematic software are upgraded, and not only avoid limitation present in legacy system escalation process, it is ensured thatIt goal systems completely upgraded, and ensure that the integrality for the data for needing to retain, increasing is reduced to target systemSystem carries out the risk of upgrading presence.

Further, the update device 13 is additionally operable to：Delete the upgrade-system being embedded in the goal systemsEnvironment.In order to reduce the risk upgraded to goal systems, therefore upgrade-system environment is embedded in goal systems, for transportingThe capable program upgraded to goal systems is simultaneously upgraded to the system software in goal systems, to avoid for upgradingInfluencing each other between program and system software, after being upgraded successfully to goal systems, need to be embedded in the goal systemsIn the upgrade-system environment delete, to save the storage resource of goal systems.
Further, the update device 13 is additionally operable to：Described in the default data storage list and being transferred toThe corresponding data of database in the goal systems under goal-selling path, recover to the database.If here,The index list of data storage list file essential when normally being run for goal systems and catalogue, for example, to dynamicThe recovery of state file system, the especially recovery to the corresponding storage pool of living document system, because living document system is being enteredDuring row upgrading, the file system set up in the corresponding storage pool of living document system can be caused to fail, therefore need rootAccording to living document system dependent instruction, by the corresponding data recovery being transferred in goal-selling path of data storage list to dynamicIn the corresponding storage pool of file system, and then realize to the file retained the need in goal systems and the guarantor in the path of catalogueStay, the data of unloading can be quickly found based on the goal-selling path of data storage list and correspondence unloading, additionally it is possible to essenceReally rapidly by the data recovery of unloading into goal systems.
Further, the update device 13 is additionally operable to：Based on the default data storage list, database instruction andThe corresponding data of database in the goal systems under the goal-selling path are transferred to, the database are carried out extensiveIt is multiple.Here, if desired recovering to the mysql databases in goal systems, then the data in the database carry out extensive, it is necessary to call the corresponding database instruction of mysql databases when multiple, based on the default data storage list, it will carry outThe corresponding data of mysql databases in the goal systems under goal-selling path are transferred to before system upgrade, are ledEnter and to the mysql databases, to realize in the mysql databases by goal systems the need for the data that retain carry out it is extensiveIt is multiple.
Further, the update device 13 is additionally operable to：Based on the data storage list, to the institute of the goal systemsState its own system environment and carry out data scrubbing.In order to remove the file abnormal residual produced in escalation process, based on need protectThe corresponding file of the data storage list stayed and the path of catalogue, by its own system environment of the goal systems,All data dumps in addition to the path of the corresponding file of the data storage list and catalogue, and then will be right in escalation processThe abnormal residual of uncontrolled file in its own system environment of goal systems cleared up, it is ensured that goal systems itself isThe controllability and security of system environment, and save the storage resource of goal systems.
In summary, the application is by the embedded upgrade-system environment in goal systems, wherein, the upgrade-system environmentIts own system environment with the goal systems is separate；The system software and nonsystematic obtained in the goal systems is softPart；The system software is upgraded in the upgrade-system environment, if upgrading successfully, its own system is switched toEnvironment is upgraded to the nonsystematic software, realizes the liter of the system software in upgrade-system environment to goal systemsLevel so that the upgrading to the system software of goal systems departs from its own system environments, no longer by the shadow of its own system environmentsRing, and then avoid interactional limitation between the ROMPaq of system software and its own system environments, in embedded literAfter succeeding in level system environments to system software upgrading, the nonsystematic software to goal systems in its own system environment is switched toUpgraded, realize the upgrading to goal systems.
