The upgrading installation package is used for upgrading the target database.
It should be noted that the upgrade installation package for upgrading the target database is obtained in advance, and it may be uploaded to the server by the database administrator.
Specifically, the upgrade installation package is a compressed file, which includes a new home directory, that is, the home directory of the upgraded target database (at this time, the upgraded target database is not generated yet, and needs to be generated according to its home directory), so that the home directory of the upgraded target database can be obtained by decompressing the upgrade installation package.
And 102, deleting the original home directory of the target database.
Specifically, since the original home directory is the home directory of the target database, the original home directory needs to be deleted after the home directory of the updated target database is obtained
And 103, generating an upgraded target database according to the backup of the original home directory and the target home directory.
Specifically, the backup of the original home directory is obtained in advance, the executable files, library files and other information of the target database all exist in the original home directory, the original home directory has the configuration files of the target database, the target home directory has the upgrade files, but the configuration files are lacked, and the configuration files are needed for generating the upgraded target database, so that the upgraded target database can be generated according to the backup of the original home directory and the target home directory which are obtained in advance.
The method for upgrading the database, provided by the embodiment of the invention, comprises the steps of acquiring a home directory in an upgrade installation package, and taking the acquired home directory as a target home directory; deleting the original home directory of the target database; and generating an upgraded target database according to the backup of the original home directory and the target home directory. According to the technical scheme provided by the invention, the target family catalog in the upgrade installation package is obtained, and the upgraded target database is generated according to the backup of the original family catalog and the target family catalog, so that the automatic upgrade of the database is realized, the labor cost is greatly saved, and the upgrade efficiency is improved.
An embodiment of the present invention provides another method for upgrading a database, as shown in fig. 2, where the method includes:
And step 203, finding the original home directory according to the path information of the original home directory.
And step 204, backing up the original home directory to obtain the backup of the original home directory.
Specifically, step 204 can be implemented by steps 204a to 204 d:
and 204a, acquiring a storage space occupied by the original home directory, and taking the acquired storage space as a first storage space.
And step 204b, acquiring the residual storage space of the server, and taking the acquired storage space as a second storage space.
And 204c, judging whether the first storage space is larger than the second storage space.
And step 204d, if the first storage space is not smaller than the second storage space, backing up the original home directory to obtain the backup of the original home directory.
Specifically, if the first storage space is smaller than the second storage space, the original home directory cannot be backed up, and the program is reported in error.
And step 205, acquiring the home directory in the upgrade installation package, and taking the acquired home directory as a target home directory.
The upgrading installation package is used for upgrading the target database.
And step 207, generating an upgraded target database according to the backup of the original home directory and the target home directory.
The method for upgrading the database, provided by the embodiment of the invention, comprises the steps of acquiring a home directory in an upgrade installation package, and taking the acquired home directory as a target home directory; deleting the original home directory of the target database; and generating an upgraded target database according to the backup of the original home directory and the target home directory. According to the technical scheme provided by the invention, the target family catalog in the upgrade installation package is obtained, and the upgraded target database is generated according to the backup of the original family catalog and the target family catalog, so that the automatic upgrade of the database is realized, the labor cost is greatly saved, and the upgrade efficiency is improved.
An embodiment of the present invention provides another method for upgrading a database, as shown in fig. 3, where the method includes:
And step 302, acquiring path information of the original home directory according to the acquired environment variable configuration information.
And step 304, backing up the original home directory to obtain the backup of the original home directory.

And step 306, acquiring the home directory in the upgrade installation package, and taking the acquired home directory as a target home directory.
The upgrading installation package is used for upgrading the target database.
And 307, storing the obtained target home directory under the first path.
Specifically, the configuration file includes a parameter file, a monitoring file, a data file, an authorization license file, and the like.
All copied back to the newly decompressed database record. Wherein
Specifically, when a data file is copied back, it is necessary to pay attention that the data file may be stored in a database directory under backup of an original home directory or may be stored in a separate disk partition, and if the data file is stored in the database directory under backup of the original home directory, when a backup name of the original home directory is different from a name of the original home directory, the data file cannot be read, so that the database directory under backup of the original home directory is directly copied to a target home directory (i.e., under a first path), and a problem that the data file may not be read can be avoided.
And 311, generating an upgraded target database according to the configuration file and the target home directory in the first path.
Specifically, the configuration file and the target home directory contain all required files of the updated target database, so that the updated target database can be generated by running the executable file in the target home directory when the configuration file and the target home directory are obtained.
And step 312, judging whether the upgraded target database is successfully generated.
Specifically, in the process of actually generating the updated target database according to the configuration file and the target home directory copied to the first path, some special situations may occur, so that the update is unsuccessful, and therefore, it is necessary to further determine whether the updated target database is successfully generated.
Specifically, if the updated target database is successfully generated, after the database is normally started, the system.sh script of the updated target database can be executed, and the database dictionary can be regenerated, so that the database characteristics of the updated target database can be normally used.
And step 314, generating a target database according to the backup of the original catalog in the first path.
It should be noted that steps 313 and 314 are remedial measures performed in the case that the upgraded target database is not successfully generated, and if the upgraded target database is not successfully generated, the original database, i.e., the target database, may be regenerated.
